Title: Method and device for opposed type hydraulic forming
Inventor: ONOE HIDEO
IPC: B21D24/16
Filed: 1988-01-30
Abstract: PURPOSE:To perform bending and reducing in one stage by forming an upper cutting edge on an upper die to be freely movable in the up-and-down direction to cut a stock by cooperating with a lower cutting edge formed on a lower holder and making a liquid in a high pressurized condition after cutting the stock by down movement of the upper die by forming a projection on the lower holder so that the stock freely abuts on the projection. CONSTITUTION:The peripheral face of a large diameter part 15 of an upper die 14 slide on and contacts with the inner peripheral face of an upper holder 11 when a stock 17 is pinched by the upper holder 11 and a lower holder 12 and the upper die 14 is moved down. By downward movement of the die 14, the stock 17 is gradually formed and is cut by slide and contact of an upper cutting edge 15a with a lower cutting edge 12a. In that time, the stock 17 abuts on the upper side corner of a projection 13 to avoid a liquid 18 from penetrating between the stock 17 and the upper die 14 but a residual liquid 18a stays in the prior state. When the die 14 moves down, bending work is performed by a stepped part 20 together with progress of reducing work by a corner part 19 of a small diameter part 16. The sealed liquid 18a is highly pressurized and is discharged from between a holder and the die 14 after final forming. Hence, bending and reducing are performed in one stage.

Title: Amplification system
Inventor: SAWAZAKI KENICHI
IPC: H03F1/26
Filed: 1981-02-17
Abstract: PURPOSE: To achieve low-noise amplification in an ultrahigh frequency range, by utilizing the output of an ultrahigh frequency oscillator whose frequency varies with an input signal voltage.  
     CONSTITUTION: A signal voltage E 0  to be amplified is applied between terminals 11 and 12. The thickness of an air layer at the semiconductor junction part of a varactor diode D constituting a ultrahigh frequency oscillator 10 varies by ΔC 1  on the basis of the voltage E 0 . This variation causes the oscillation frequency f 1  of the oscillator 10 vary by ΔF 1 . The output of the frequency f 1 +Δf 1  of this oscillator 10 is supplied to a mixer 21 together with the output of the frequency f 2  of an ultrahigh frequency oscillator 20 to generate an intermediate frequency f 3 =f 1 +Δf 1 -f 2  by conversion. This signal f 3  is amplified by an amplifier 22 and then applied to a frequency discriminator 23, from which an amplified signal voltage is obtained. Thus, low-noise amplification in the ultrahigh frequency range is achieved.

Title: Fsk receiver
Inventor: YOSHIHARA TAKAO
IPC: H04B3/54
Filed: 1991-01-23
Abstract: PURPOSE:To prevent a reception error by providing a gate circuit interrupting a high frequency signal for a prescribed time period only at a specific phase of a commercial frequency voltage to the receiver so as to attenuate the high frequency signal with a large amplitude. CONSTITUTION:A gate circuit 12 interrupting a high frequency signal is provided between a signal demultiplexer circuit 13 and an FSK demodulation circuit 8. The gate 12 is switched by an output signal from a phase detection circuit 6A to switch an output signal of a secondary winding of a coupling transformer 4 to interrupt high frequency signals f1, f2 for a prescribed time width only at phases of a commercial frequency voltage close to 0 deg. and 180 deg.. Since an intermittent part exists in an input signal to a BPF circuit 7 by a control signal, the high frequency signal with a large amplitude is attenuated at the intermittent part and even when a signal with a small amplitude comes, the high frequency signal does not give influence on the signal with a small amplitude.

Title: Duplex optical communication system
Inventor: OKAYAMA HIDEAKI
IPC: H04J14/00
Filed: 1990-01-31
Abstract: PURPOSE:To connect lots of subscriber terminal equipments with a few number of wavelengths and to attain optical wavelength multiplex communication with high accuracy and at broad band by using a different wavelength for each call setting so as to attain a duplex optical communication between an exchange and a subscriber terminal equipment. CONSTITUTION:In the case of making a call setting from a subscriber terminal equipment 20a to an exchange 10, a wavelength of a wavelength variable light source 22a is tuned to a wavelength lambdaa and a call request signal is superimposed on an output light by an optical modulator 23a. A receiver 13a of a station 10 receives the signal and selects a nonuse wavelength lambdan and superimposes the operating information onto the light lambdaa by an optical modulator 12a and sends the result to a terminal equipment 20a via an optical fiber 30. A receiver 21a of the terminal equipment 20a reads the superimposing information and sends a call acknowledge signal to start communication to the station 10. At the communication the terminal equipment 20a uses an optical modulator 23a to superimpose the information onto the light lambdan and sends the result to the station 10 via the optical fiber 31. The station 10 uses the receiver 13n to receive the signal lambdan and uses the optical modulator 12n to superimpose a signal onto the output light from a light source 11n and sends the result to the terminal equipment 20a via the optical fiber 30. Thus, a different wavelength is used for each call setting in this way.
