A frequency multiplier circuit device having a delay circuit including a plurality of delay elements, and a selector circuit for selecting the number of delay elements for every output stage of the delay circuit. A reference input signal and an output from the selector circuit for determining the period of the reference input signal are input to a phase comparator. The selector circuit is controlled on the basis of an output from the phase comparator to select the number of delay elements of the...

A method of making a digital photograph composed of a moving water element and still element by applying a known computer image processing system, and a digital photograph made by this method, involves taking a basic photograph indicating a realistic image of still elements and photographs taken by applying a series of shutter speeds. A series of digital images corresponding to the above-mentioned photographs are indicated on a monitor of the processing system, and an image indicating a realisti...

In the color image transmission system between a pair of computer image processing systems A & B, a common basic color such as R.G.B. basic color is firstly decided, then this common basic color is transmitted from the system A to the system B so that a digital image (X) is indicated on the monitor of the system B, the color matching operation is applied to the digital image (X) to substantially match the displayed color thereof and decide a correction value a from color data indicated on the mo...

Bearing pieces are formed on both sides of the rear end of a clincher arm which includes a clincher table for bending a staple at the front end thereof. A magazine member to which staples are loaded and a driver arm for driving out a staple fed from the magazine member are pivotally mounted on an axle, which is provided at the rear ends of the bearing pieces. A handle member is rotatably disposed above the driver arm. A rotation supporting shaft of the handle member is provided at a position som...

When transmitting an image between a pair of computer image processing systems A and B, a common color image Z is used as a medium image, the medium image is read as digital data into the computer of the system B from the system A, the color of the digital image displayed on the monitor of the computer of the system B is adjusted to substantially match the color of the common image Z by operating the conventional color adjustment system of the computer, the deviation from the origin (zero point)...

An electronic still camera includes a picture signal processing circuit and a compression processing circuit. A photographed picture signal is subject to compression processing in the compressing processing circuit after being processed in the picture signal processing circuit. Electric power supply from a power source circuit is controlled by a control circuit. Electric power is supplied only to the picture signal processing circuit at the time of picture processing, while electric power is sup...

Disclosed is a process for producing the magnesium salt of sulfonic acids and sulfuric esters comprising the step of neutralizing the sulfonic acids and sulfuric esters with an aqueous dispersion containing: (1) at least one neutralizing agent selected from the group consisting of magnesium oxide and magnesium hydroxide, and; (2) at least one neutralizing accelerator selected from the group consisting of benzoic acid, citric acid, malic acid, phosphoric acid, polyphosphoric acid and water-solubl...

In an electronic musical instrument, numerical values corresponding to respective notes are generated on a time-shared basis, the generated numerical values are cumulatively added for each note in synchronism with a predetermined time slot and carry signals coming out as results of the accumulations of the respective numerical values respectively constitute note frequency signals. By simplifying a tone source circuit in this manner and by selecting generated frequency signals in accordance with ...

An automatic calendar is provided which permits a regular change in the display from the end of the month to the first day of the next month to be achieved without requiring adjustment over a prolonged period of time, by employing a unique arrangement of numerals providing a display of date. The calendar comprises a unit's day display member having an indication of numerals in the sequence of 0, 1, 1, 2, 3, 4, 5, 6, 7, 8 and 9 at an equal interval, and a tens' day display member having an indica...

A fully electronic car clock with digital display is provided in which the counter circuit of the car clock is connected to a car battery through an engine key switch to be driven therefrom, and the clock display is interlocked with the engine key switch so as to be energized or deenergized in accordance with the ON-OFF position thereof in order to avoid draining the battery. A method of time setting the car clock is also proposed.
