Title: Semiconductor variable-capacity element
Inventor: KAMIYAMA KENICHI
IPC: H01L29/94
Filed: 1990-04-06
Abstract: PURPOSE:To attain a large variation in capacity and a large performance index and also to make a leak current small by forming an N-type semiconductor layer and others sequentially on a P-type semiconductor layer or by forming the P-type semiconductor layer and others sequentially on the N-type semiconductor layer. CONSTITUTION:After an N-type semiconductor layer 2, an insulating film 3 and an electrode 4 are formed on a P-type semiconductor layer 1, an ohmic electrode 5 is formed on the rear side of a crystal. When the layer 1 is grounded and a negative voltage is impressed on the electrode 4, the impressed voltage makes the layer 1 inject holes into the layer 2 and the injected holes reach an interface between the layer 2 and the film 3 and give a capacity value. When the negative voltage is increased, the number of holes increases exponentially and the capacity value of a variable-capacity element increases to a large extent. When the electrode 4 is set at 0V, the surface of the film 2 on the film 3 side turns to have a flat energy band structure and the capacity value of the variable-capacity element becomes minimum. In the case when the layer 1, the film 3 and the electrode 4 are formed on the layer 2 and a positive voltage is impressed on the electrode 4, the capacity value of the variable-capacity element becomes minimum as well. According to this constitution, a small variation in capacity and a large performance index are attained and a leak current can be made small.

Inventor: SASAKI HIDEMI
IPC: H04N5/225
Filed: 1990-04-09
Abstract: PURPOSE:To improve the operability by devising a mode changeover switch such that the video mode is set in interlocking with the closing of a cover, the changeover function is invalidated when the cover is further closed to select the camera mode forcibly and the function is validated when the cover is opened. CONSTITUTION:Since video and audio input output terminals 6, 7 are not in use at pickup, while a cover 8 is closed, even when a mode changeover switch 10 is in the video mode C, the switch 10 is invalidated by a camera priority switch 12 to obtain a camera mode B. On the other hand, when a monitor or the like is in use at pickup, since the terminals 6, 7 are used, then the cover 8 is opened. The switch 13 is opened, the switch 10 is validated and the video mode C is changed into the camera mode B. When a video tape is monitored, since the terminals 6, 7 are used, the cover 8 is opened, a switch 13 is opened and the switch 10 is valid, but no mode changeover is required because the video mode is selected. Thus, the operability is improved to prevent mis- operation.

Title: Drive system for reel turntable of tape recorder
Inventor: KOIKE TADASHI
IPC: B65H59/38
Filed: 1979-07-20
Abstract: PURPOSE: To obtain stable and constant tape running speed, by changing the rotating speed through the feedback of the torque of the reel turntable produced accompanied with greater tape winding diameter to the drive motor.  
     CONSTITUTION: The power of the motor 29 is delivered to the reel turntable 21 via the drive wheel 30, idler 28 and belt 31. The reel turntable 21 is not provided with the slip mechanism different from conventional systems. With the operating lever 27 shifted left, rewinding mode is obtained and with it shifted right, fast feed or reproducing mode is obtained. As the tape winding diameter of the reel turntable  21 is greater, the torque of the reel turntable 21 is increased. Since no slip mechanism is provided with the reel turntable 21, the torque operated to the reel turntable 21 is directly operated to the motor 29 so that the number of revolutions of the  motor can be lowered. Thus, the tape running speed always constant can be obtained.

Filed: 1989-04-14
Abstract: PURPOSE:To open and close a cassette cover without loading the cassette cover with simple constitution by providing two layers of magnets, superposing a 2nd magnet on a 1st magnet so that the polarity of the 2nd magnet is made different from that of the 1st magnet and releasing the attraction of the cassette cover. CONSTITUTION:When an arm 4 descends, a fixed magnet 11 is attracted to an iron plate 1b stuck to the cassette cover 1a. Meanwhile, while the arm 4 is descending, a motor 18 is driven and a movable magnet 12 starts to rotate. After the fixed magnet 11 is attracted to the iron plate 1a, the movable magnet 12 rotates completely by 180 deg. and magnetic force becomes strong, so that the iron plate 11b is attracted. The arm 4 ascends in such a state and the cassette cover 1a is opened, thereby exchanging a film. When the film is exchanged, the arm 4 descends again. However, it does not descend to the bottom but stops on the way. The magnet is made in a feeble state and the cassette cover 1b drops by gravity. Thereafter, the cassette cover is locked and discharged top an insertion port.
