Title: Multi-channel reception recording/reproducing device
Inventor: WATANABE MASAO
IPC: G11B20/02
Filed: 1989-02-02
Abstract: PURPOSE:To receive the high frequency signals of plural broadcasting or transmitting stations with a simple system constitution and to record/reproduce plural information by collectively recording and reproducing the signals of different high frequencies in the form of high frequency signals undergone the conversion of frequencies. CONSTITUTION:The high frequency signals of plural broadcasting or transmitting stations which are supplied from an input device 8 and amplified by a high frequency amplifier 9 are mixed with the high frequency signals of a local oscillator 10 via a frequency mixer 11. These mixed signals undergo the band limitation of frequencies via a BPF 12 and are amplified by a high frequency amplifier 13. These amplified high frequency signals are recorded and reproduced by a recording/reproducing device 14. The high frequency signals which are reproduced and amplified by a high frequency amplifier 15 are mixed with the high frequency signals of the oscillator 10 via a frequency mixer 16. These mixed signals are led to a receiver 19 via an output device 18. The high frequency signal of a specific broadcasting or transmitting station is selected out of those high frequency signals led to the receiver 19. Thus the receiver 19 can obtain the information. As a result, the system constitution is simplified.

Filed: 1992-02-12
Abstract: PURPOSE:To sufficiently diffuse both N-type impurities and P-type impurities which have been introduced into gate electrodes by a method wherein an N-type gate electrode is annealed longer than a P-type gate electrode. CONSTITUTION:Arsenic to be used as N-type impurities is ion-implanted into a polycrystalline silicon film 17 on the side of an N-type MOSFET; after that, an annealing operation is performed at 1000 deg.C for about 20 second. Then, polycrystalline silicon films 17a, 17b are patterned; gate electrodes for the FET are formed. Ton seeds whose type is the same as that of a channel for the MOSFET are ion-implanted, in a self-aligned manner, into the gate electrodes as well as a P-type well layer and an N-type well layer on bothe sides of them; they are diffused; N-type diffusion layers 18a, 18b and P-type diffusion layers 19a, 19b which are to be used as source regions and drain regions are formed. As ion implantation conditions, arsenic is used for an N-type region and boron is used for a P-type region. After that, the gate electrodes 17a, 17b and the diffusion layers 18a, 18b, 19a, 19b are annealed at 1000 deg.C for 20 seconds. Thereby, it is possible to complete the FET in which the impurities the have been diffused sufficiently into the N-type and P-type gate electrodes.

Title: Gear type torque converter
Inventor: MURAYAMA KATSUHIKO
IPC: F16H3/72
Filed: 1987-02-04
Abstract: PURPOSE:To form an output shaft gear to change its axial torque in no relation to the range of rotary speed of an input shaft gear, by mounting planet gears to a supporting frame providing a brake device in which the planet gear is able to revolve on its own axis while the planet gear freely rotates around concentrically with input and output shafts with the different direction of rotation. CONSTITUTION:An output shaft gear 2 rotates reversely to an input shaft gear 1, and planet gears 3 move in the same direction to the direction of rotation of the gear 1. And in case of holding a supporting frame 4 in a free condition, almost no axial torque of the gear 1 is transmitted to the gear 2 because the gear 3 generates the sane phenomenon to the roller in a rolling bearing device. While in case of completely holding the supporting frame 4 by a brake, all the axial torque of the gear 1 is transmitted to the gear 2 through the gear 3. Next, when the gear 1 maintains its rotary speed to a fixed value, the axial torque, transmitted to the gear 2, has no relation to the range of speed of the gear 1 changing in proportion to the change of brake force to the supporting frame 4.

Filed: 1993-02-15
Abstract: PURPOSE:To supply stable constant voltage power regardless of the magnitude of the fluctuation of a primary power supply by detecting the voltage of the primary power supply and changing the conversion ratio of a transformer. CONSTITUTION:When the voltage of a primary power supply 1 is normal, a drive circuit 8 is driven by the signal of a pulse width control circuit 9, a transistor 4 is operated by a switch, and load 7 is supplied with constant voltage power. When the voltage of the primary power supply 1 exceeds the voltage control range of the pulse width control circuit 9 and a voltage drop is generated, the voltage of the primary power supply 1 on the outside of the pulse control of an input voltage drop is detected by an input voltage detector 12, the detecting signal is output to a drive circuit 13, and a transistor 11 is operated, thus changing the winding ratio of a transformer 10, then transmitting power. Since the winding ratio of the transformer 10 is altered at that time, the pulse width of the pulse width control circuit 9 is reduced, and the range of output voltage control is shifted, thus stabilizing output voltage.

Abstract: PURPOSE:To enable a single element to perform a flip flop operation and obtain a large degree of the multiplication, by providing two rooms with extensible elastic partitions in a face-to-face relation with a space apart from each other in the enclosed fixed-wall room. CONSTITUTION:When a room 7, consisting of an elastic partition 2, is in a state of low pressure, a fluid at a constant pressure fed from a supply port 17 flows going into the room 7 through a throttling port 18 and into a room 9 from a small hole 6 in an end face 4, being discharged through a discharge port 16 having a throttling port 15. When a pressure change positive with respect to the steady pressure value in a room 8 is inducted from an inlet-outlet port 14, an elastic partition 3 is extended to permit an end face 5 to approach the end face 4 causing a flow resistance of the hole 6 to be increased for the fluid to flow out from said hole. Accordingly, a pressure in the room 7 is raised to extend the elastic partition 2. Finally the end faces 4, 5 are closely attached to allow a pressure in the room 7 to be equal to that from the supply port 17. The fluid at this pressure fed from an outlet port 12 drives the fluid operating device.
