A vertical synchronizing system, in which a trigger signal produced by frequency doubling the horizontal sync signal and frequency dividing the resultant signal by 525 is compared with the vertical sync signal to bring the trigger signal into sync with the vertical sync signal.

This specification discloses a tuning indicator device for a television receiver, wherein a waveform having a slope depending upon the horizontal or vertical synchronizing circuit is sliced at upper and lower levels in accordance with a voltage which depends upon the state of tuning, and a rectangular wave is formed from the sloped portion of said sliced waveform to be indicated on the picture tube screen as a tuning indication signal.

An automatic frequency control (AFC) in which the sync signal and flyback signal are compared to detect the direction and amount of deviation of the flyback signal with respect to the sync signal, thereby producing AFC voltage pulses to control the oscillator of the horizontal circuit in the television set. The polarity of the pulses is determined by the direction or sense of deviation, and the pulse width is determined by the amount of deviation.

A fish detection sonar is provided wherein a receiver has a display device comprising a rotary disk having a display element mounted thereupon, and a scale disk disposed coaxially of and in opposed relation with the rotary disk; the ultrasonic signal transmitted from a transmitter into the sea is immediately received by the receiver so that the display element may be turned on or energized in response to the level of the received signal, thereby displaying the surface of the sea; and the receive...

A column-shift type, shift lever arrangement for operating an automatic power transmission includes a shift locking mechanism which prevents a vehicle's driver from changing the position of a transmission shift lever. The shift locking mechanism engages an annular groove formed in a compression rod at a location neighboring one end thereof so as to mechanically lock the movement of the shift lever arrangement, until the vehicular driver depresses a brake pedal once, after engine starting is perf...

An image-forming apparatus includes an electron source including one or more than one electron-emitting devices on a substrate, each electron-emitting device having a pair of oppositely disposed device electrodes, an electroconductive film connected to the pair of device electrodes and an electron-emitting region formed in part of the electroconductive film accompanied by a carbonaceous film which contains carbon or carbon compound as principal ingredient and is formed on and in a vicinity of th...

A hydrogen storing member which comprises at least two kinds of hydrogen storing materials comprising a first hydrogen storing material and a second hydrogen storing material capable of releasing or storing hydrogen in a range of at least one of temperature and pressure at which the first hydrogen storing material is in the .beta. phase having a high capacity for storing hydrogen.

In a motor device having a motor, a reduction mechanism and a housing with an installation leg integrally formed therewith by a pair of dies parting in an axial direction of an output shaft of the reduction mechanism, the installation leg is composed of a side surface coming in surface contact with a frame, a first recess portion for holding a nut whose entire inner surface is opened at least on one side of the housing in a die parting direction of the dies and a second recess portion for insert...

A hydrogen storing member which comprises at least two kinds of hydrogen storing materials comprising a first hydrogen storing material and a second hydrogen storing material capable of releasing or storing hydrogen in a range of at least one of temperature and pressure at which the first hydrogen storing material is in the .beta. phase having a high capacity for storing hydrogen.
