A pair of trousers including two leg coverings for covering two legs of a wearer, respectively, each of the leg coverings including a front and a rear half, one or both of the front and rear halves having a crease line extending over a vertical length thereof, and two side portions extending along the crease line on both sides of the crease line, respectively; and one or more adhesive tapes which connect respective inner surfaces of the side portions to each other over an entire length of the si...

A collapsible rear view mirror apparatus comprises a rear view mirror, a mirror arm, a support member to be fixed to an automobile body, and a ball-and-socket joint constituted by a ball element, a first socket element to be fixedly attached to the support member, and a second socket element movable within this support member. The ball element is secured to the base portion of the mirror arm. The ball element has at least one ridge on its surface. The second socket element has on its concave sur...

A diversity system using a phase control circuit for combining respective outputs of a plurality of routes of different path lengths transferring the same analog signal. An analog variable delay circuit, which is capable of controlling its amount of delay by varying the repetition frequency of clock pulses, and a low-pass filter connected to the output of the analog variable delay circuit are inserted in each route other than a reference one of the plurality of receiving routes. A phase differen...

In a method for measuring chlorophyll of a leaf of a plant, the light having passed through the leaf is divided into a light component of a shorter wavelength the amount of which changes with the amount of chlorophyll and another component of a longer wavelength the amount of which does not change with the amount of chlorophyll. The amount of these two components are measured at the same time and the difference therebetween is used for determining the amount of chlorophyll contained in the leaf....

A frequency synchronizing system for satellite communication, in which a reference frequency coming from a communications satellite is received by a receiving circuit. A first frequency variable oscillator is provided for generating a transmission signal. A second receiving circuit is provided for receiving through the communications satellite the transmission signal which is the output from the first frequency variable oscillator, A first frequency control circuit is provided for controlling th...

An image forming apparatus having a developing unit for developing a latent image electrostatically formed on a photoconductive element or similar image carrier by a developer, or toner, to produce a toner image, and a cartridge removably mounted on the apparatus for supplying a toner thereto. An operator is directed through the steps of toner re-supply from the removal of the used toner cartridge to the insertion of a new toner cartridge while watching instructions which sequentially appear on ...

A feed forward microwave power amplifier having a divider for dividing an input signal into two parts, a first main amplifier for amplifying one of the divided signals, means for providing a part of the output of the first amplifier as a signal S.sub.1, means for providing a signal S.sub.2 by another output of the divider, a subtractor for providing the difference between S.sub.2 and S.sub.1, a second amplifier having the same gain as that of the first amplifier for amplifying this difference, a...

A fluorescent display device capable of forming a die bond layer into a desired and uniform thickness, resulting in minimizing adverse affection of thermal stress occurring during the manufacturing and accurately accomplishing wire bonding operation to lead to an improvement in its reliability. Also, a method for manufacturing the device. The fluorescent display device is so constructed that an insulating bank of a frame-like shape is provided between a die bonding pad and bonding pads and a die...

A controlled induction motor device employs a three-phase induction motor whose rotor has a rotor winding of a relatively large resistance to reduce the electrical time constant of the rotor to be equal to or less than the reciprocal of the frequency of the three-phase AC power which is supplied to the motor. A controllable rectifier is inserted in one of the three-phase AC power lines supplying power to the motor in order to intermittently supply the three-phase power to the motor, whereby the ...
