Title: Photo electromotive force element
Inventor: MUROZONO MIKIO
IPC: G01J1/02
Filed: 1978-08-23
Abstract: PURPOSE:To improve short-wave sensitivity and also to reduce the cost of an element by leaving a 1st semiconductor layer of one conduction type in an island or belt shape and by forming a 2nd semiconductor layer of the conduction type opposing to that of the 1st semiconductor layer. CONSTITUTION:At the side where the phote detection surface of substrate 21 is formed, several island-shaped exposure parts 21' of substrate 21 are left to form high-impurity-density diffusion layer 22. Short-wavelength light through a reflection- preventive film is effectively converted into electric energy, which is led out via external electrode 25. Diffusion layer 22 may be 1 to 1.5mum in depth. Then, island- shaped regions 21' are designed only with their diameter not more than 100 to 140mum.

Title: Reel rest driving device for tape player
Inventor: AKITA KAZUNORI
IPC: G11B15/30
Filed: 1985-05-13
Abstract: PURPOSE:To wind surely a magnetic tape to improve the capacity with respect to wow or the like by applying the first and the second torques to a reel rest device from the first and the second rotating bodies provided on the same providing shaft and engaging and releasing them surely with an idler base. CONSTITUTION:The rotation of a motor 101 is transmitted to a pulley 310 from a motor pulley 102 through an idler belt 180. The rotation number of the motor 101 is reduced by a diameter ratio of the motor pulley 102 to the pulley 310. The rotation of the pulley 310 is transmitted to a slip gear 250 of the reel rest device through a gear PL320 from a gear idler PL314 press-fitted to the upper part of the pulley 310. The rotation number of this reel rest 201 is determined by a pitch diameter ratio of the slip gear 250 to the gear idler PL320. The elastic force of a spring reel 249 is used to abut the slip gear 250 on a felt 245 for the purpose of absorbing the difference of rotational speed between the slip gear 250 and the reel rest 201.

Title: Noise cancel circuit
Inventor: MIYAKE KIMITAKE
IPC: H04N5/21
Filed: 1986-05-06
Abstract: PURPOSE:To remove noise in the edge part of a signal waveform without deteriorating picture quality by detecting parts whose levels change beyond the prescribed level out of an input or output video signal and synthesizing the detected parts with a signal passing through a bypass filter and the input or output video signal. CONSTITUTION:If the level of an output signal suddenly changes to produce the edge part 17, the output waveform of the bypass filter 8 develops the differential waveform of the edge part 17. Generally the differential waveform and the waveform of a signal (a) develop the noise N. When the differential waveform is passed through a limiter 9, it becomes a waveform C cut at the prescribed level of the limiter. As figure shows, the noise N at the level of the limiter is removed out of the waveform. Moreover the edge part of the waveform does not become dull and the distortion of the waveform never occurs.

Title: Screen device
Inventor: KIMURA SAKAE
IPC: G03B21/56
Filed: 1989-04-24
Abstract: PURPOSE:To easily spread a screen when it needs to be used and to easily fold it when it need not to be used by attaching a flexible screen which can be folded to a rib part which radially unfolds. CONSTITUTION:In the case of spreading the screen, a movable cylindrical body 24 is moved along a supporter 10 to the tip side of the supporter 10. The movable cylindrical body 24 gets over an pawl 26 and stops at a position where it abuts on a stopper 25. Since the pawl 26 is restored by a spring which is installed in the supporter 10 at such a time, the cylindrical body 24 is prevented from returning to a home position. When the cylindrical body 24 is moved upward, the rib part 20 is pushed up by an auxiliary rib part 23 whose center side is supported by the cylindrical body 24 and is turned centering around a turn supporting part 19, so that a screen main body 22 attached to the turn supporting part 19 is spread. By turning the lower end part 11 of the supporter 10 centering around a fulcrum pin 13 in a state where a screw 14 for fixing is loosened, the angle of the lower end part 11 against the supporter 10 can be set at an optional value. The bottom end side of the lower end part 11 is supported through a knob 16, which is used also as a supporting leg.

Abstract: PURPOSE:To positively balance a temperature in a container with an open air temperature by setting the pressure in the container to larger initial pressure than an absolute value of the set pressure, and thereafter, allowing the pressure in the container to escape to the outside and varying positively the pressure in the container to the set pressure. CONSTITUTION:When pressurized air from a regulator 2 passes through solenoid valves SV1, SV2...SV5 and supplied to a container 5 and a master 6, since original pressure is larger than initial pressure P0, pressure in the container 5 and the master 6 rises quickly. Subsequently, when the pressure in the container 5 reaches the pressure P0, a switch 9 operates and the solenoid SV1 is closed. Thereafter, in a test pressure leading-in process, a supply port of the solenoid valve SV2 is closed, and also, an output port of the valve SV2 and an exhaust port are connected. As a result, the container 5 and the master 6 are connected to a secondary side of a secondary regulator 3, pressurized air corresponding to differential pressure DELTAP of the pressure P0 and the test pressure Pt is emitted to the outside from the regulator 3, the pressure in the container 5 and the master 6 falls to the pressure Pt, and a temperature in those containers is balanced with an open air temperature in a short time.
