Title: Heterodyne relay system
Inventor: KITAHARA YUJI
IPC: H04B7/15
Filed: 1986-02-28
Abstract: PURPOSE:To reduce phase jitter and nonlinear distortion while keeping the high frequency stability by selecting the frequency (f0) of a deviation frequency oscillator to a specific relation with respect to a transmission/reception frequency difference (fS). CONSTITUTION:The relation of f0=fS+ or -fIFX2 is given in the deviation system, where f0 is the oscillation frequency of a deviation frequency oscillator, fS is a transmission/reception signal frequency difference and fIF is an intermediate frequency in the heterodyne relay, the nonlinear distortion caused in the transmission section and the reception section is compensated at every relaying while the high frequency stability is being kept. Since the reception station oscillating frequency fRL is lower than the reception signal frequency fR in this case, the phase of the nonlinear distortion component is unchanged. Since the distortion component of the oscillated frequency of the transmission section is higher than that of the transmission signal frequency fTL in a transmitter 6 depending on the deviation frequency system, the phase is converted by 180 deg., the polarity is inverted from that of the nonlinear distortion caused by the transmitter 6 and the nonlinear distortion component is reduced.

Title: Picture reader
Inventor: HONMA TSUYOSHI
IPC: H04N1/04
Filed: 1986-02-28
Abstract: PURPOSE:To prevent the excess transfer of a picture signal by stopping immediately an original read when a picture signal input enable signal from an external device is not obtained during the transfer of picture signal. CONSTITUTION:An original reader uses a CCD picture signal section signal obtained from a timing generating circuit 209 to supervise the presence/absence of the input of a control signal ACK of an interface circuit 207 from an external device 250.

Title: Throttle device for pneumatic tool
Inventor: KANEKAWA YUJI
IPC: G11B21/02
Filed: 1989-02-22
Abstract: PURPOSE:To eliminate the overs and shorts of a clamping time, enable clamping at a defined torque, and eliminate the waste of a working time by providing a pneumatic circuit for operating a pneumatic tool only for a certain set time merely by once pressing the push button of a throttle valve. CONSTITUTION:When the air feeding circuit 6 of a control box 1 is in an open condition, as the throttle valve 29 of a pneumatic tool is opened by once pressing a throttle button, air reaching the throttle portion pushes the valve body of the throttle valve 29 against a return spring to keep same in an open condition. On the other hand, since a relay valve becomes a closed condition through an air signal circuit, air which is collected in an air tank 5 to keep the air feeding circuit 6 in an open condition is gradually released into atmosphere, to make the air feeding circuit 6 into a closed condition. Since the flow of the air in the air tank 5 is limited by the flow control of a throttle valve, it takes time for the air feeding circuit to get from the open condition to the closed condition, enabling the pneumatic tool to continue operating during this time.

IPC: C23F4/00
Filed: 1986-02-28
Abstract: PURPOSE:To prevent consumption of electric power according to frequency conversion by generating glow discharge via a device having voltage trailing characteristics without using an oscillator even if using a commercial electric power source. CONSTITUTION:Electric power supplied from a commercial electric power source 1 is fed to a reaction chamber 3 via a leakage transformer 2 wherein commer cial voltage is risen until voltage required to glow discharge without converting frequency and also stabilized discharge is obtained by voltage trailing character istic. In other words, when discharge is started between a dummy base body 5 for etching and an electrode plate 4 for glow discharge, current is allowed to flow by using this leakage transformer 2. In such a case that voltage is reduced according to increase of current, when reduced until some degree, the prescribed amount of electric power is stationarily fed and a discharge state for stable etching can be maintained. In such a way, electric power sup plied from the commercial electric power source 1 can be effectively fed.

Title: Temperature controller
Inventor: IKEHARA TAKASHI
IPC: G05D23/19
Filed: 1982-03-19
Abstract: PURPOSE:To increase the lifetime of a relay contact, by latching the coil of a latch relay connected to a heater with the signal which is supplied via a Schmitt circuit and a hysteresis means by the temperature of detection and therefore reducing the opening/closing times of the relay contact. CONSTITUTION:Transistors TR27 and TR26 are turned on and off when the temperature of a heater 2 is lower than that set by a volume 25 with a high level of resistance of a thermistor 31. At the same time, a temperature detecting means A is set at an H output, and TR15 and TR14 of a Schmitt circuit B are turned off and on respectively with TR4 and TR11 turned on. Thus an inverting means D has an L output, and a TR8 is turned off. Then a charging current flows instantaneously to a capacitor 6 to close and latch a contact 3A. When the heater 2 conducts to raise up the temperature, the state of each part is inverted. Then the capacitor 6 is discharged to release the latching state. In this case, the temperature of the thermistor 31 drops, and the TR15 is turned on. Thus the base potential of the TR26 is set at a high level owing to a diode 22 and a resistance 21, and the temperature of the thermistor 31 is lowered less than the level obtained when the heater 2 is turned off. Then the thermistor 31 is finally turned on to draw a hysteresis.

Abstract: PURPOSE:To permit one person to freely execute the re-stringing and tension adjustment of a gut by using a roller and a pin for a part to turn the stringing direction of the gut. CONSTITUTION:At the time of stringing the gut anew, gut supporting frames 11a and 11b are fitted in the recessed part of a frame 34, and an elliptic gut supporting frame is formed. Thereafter, a gut 9 is made to penetrate through a start point hole 34d, the gut 9 is hooked to a roller 12, to a roller 14,..., to a roller 16, next, to a roller 18, to a roller 20,..., and to a roller 24, and the stringing is completed in a horizontal direction and a vertical direction.
