Title: Differential pressure controller
Inventor: TAKIGUCHI ETSUO
IPC: G05D16/00
Filed: 1981-09-18
Abstract: PURPOSE:To hold accurately a constant pressure, by separating a pressure chamber and a residual pressure chamber from each other through a diaphragm and detecting the position of the diaphragm to generate a control signal and providing a differential pressure controller which applies this control signal to a reducing valve. CONSTITUTION:Air is sent from a compressor into a low-pressure casting furnace 12  through a pressure controlling valve 14 and a solenoid switching valve 16a, and a pressure is held for a certain time to perform the low-pressure casting. Next, the valve 16a  is closed, and a solenoid switching valve 16a is opened, and air for control of residual  pressure is sent into the furnace. Simultaneously, a reducing valve 34 is opened to lower  the pressure in the furnace. This pressure lowering is transmitted to a pressure chamber 24 of a differential pressure controller 20 through a pressure piping. Since air controlled to a required residual pressure is sent to a differential pressure chamber 26 from  the pressure piping connected just after a residual pressure controlling valve 18, the  differential pressure is detected by a diaphragm 22 of the controller 20, and a proximate switch is operated in the state where the differential pressure chamber 26 is completely balanced between the dropping air pressure in the pressure chamber and the required residual pressure in the residual pressure chamber 26, and the valve 34 is closed  in this state.

Title: Amplifier for eliminating distortion by combining hyperbolic tangent transfer function and hyperbolic sine transfer function, and method therefor
Inventor: FINOL JESUS L
IPC: H03F1/32
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To provide an amplifier that eliminates distortion by combining a hyperbolic tangent transfer function and a hyperbolic sine transfer function and to provide its method. SOLUTION: A differential amplifier 10 receives a differential input signal (VIN). A 1st attenuator 12 attenuates the input signal and the attenuated signal is inputted to a hyperbolic tangent amplifier 16. A 2nd attenuator 14 attenuates the input signal and the attenuated signal is inputted to a hyperbolic sine amplifier 18. Signals to be inputted to the hyperbolic tangent amplifier and the hyperbolic sine amplifier are attenuated independently. Each transfer function of the hyperbolic tangent amplifier and the hyperbolic sine amplifier consists of a linear region and a nonlinear region. An adder 26 sums outputs of the hyperbolic tangent amplifier and the hyperbolic sine amplifier so that the nonlinear region of the hyperbolic tangent amplifier acts like canceling the nonlinear region of the hyperbolic sine amplifier.  The overall transfer function of the differential amplifier is linear over a wide amplitude range of the input signal because the nonlinear regions of the amplifiers are cancelled together.

Abstract: PURPOSE:To stabilize printing quality by providing a free roller which contacts the ends of a plurality of ink kneading rollers and causing the free roller to perform printing action by its own weight according to a force received from the ink kneading roller. CONSTITUTION:Metallic ink kneading rollers 7, 7' are made of light metal such as aluminium, and the tack value of ink gradually increases as it is kneaded and, subsequently, its adhesive force which works in a tangential direction at a contact point between a rubber form roller 5 and a metallic roller 7 with an unfixed shaft end increases. Then when the tack value of ink becomes proper for printing, the adhesive force of ink and the combined force of the weights of a heavy object 16 and the metallic roller 7 are balanced to cause the metallic roller 7 to begin revolving on the periphery of the rubber form roller 5 whenever the adhesive force of ink increases, even if slightly. Consequently, it is possible to easily judge whether the property of printing ink is suitable by observing a change in the position of the shaft of the metallic roller 7, thereby contriving stabilization of printing quality.

Title: Auto-strobe photographing device
Inventor: SERIKAWA YOSHIO
IPC: H05B41/32
Filed: 1985-07-09
Abstract: PURPOSE:To photograph with a strobe of large capacity practically by providing a trigger signal generating means which generates a trigger signal to allow plural strobe light emission light sources to emit strobe light successively or to allow them to emit light again simultaneously with completion of charging of these strobe light emission light sources. CONSTITUTION:Charging completion and shutter full opening are discriminated by a trigger signal generating circuit 8, and a one shot pulse in the high level is generated in the first trigger signal S3 and is sent to the first strobe device 1 to start strobe light emission. When shutter full opening and charging completion are discriminated by a trigger signal generating circuit 10 and a one shot pulse in the high level is generated in the second trigger signal S9, strobe light emission of the second trigger signal S9, strobe light emission of the second strobe device 2 is started. When a photometric part 3 detects that the reflected light from an object of the first and second strobe light emission reaches a correct exposure value, a one shot pulse in the high level is generated in a light emission stop signal S11 to stop light emission of the strobe device 2. Thus, strobe photographing equivalent to that using the strobe of large GN is performed with the strobe of small NG.

Title: Generation method for modulation signal in optical scanner
Inventor: SHIMADA KAZUYUKI
IPC: G02F1/01
Filed: 1986-06-25
Abstract: PURPOSE:To set the on off ratio of a light source in one dot almost constant by synchronizing picture element data transferred by a picture element clock with a picture element clock by means of the 1st flip flop and delaying said data by half the picture element clock by means of the 2nd flip flop. CONSTITUTION:The picture element data is inputted to the input D of the 1st flip flop 10. Since the inversion signal of the picture element clock, that is, a signal obtained by delaying the phase of the picture element clock by 180 deg., is inputted to the input K of the 2nd flip flop 12, the inverse of the output Q of the flip flop 12 ends up a signal obtained by delaying the inverse of a signal Q by half the picture element clock. After all the 1st flip flop 10 synchronizes the picture element data with the picture element clock, and by the output Q, signal 1 (the inverse of Q) and the 2nd flip flop 12, said data is delayed by (t). Signals 1 (the inverse of Q) and 2 (the inverse of Q) are impressed on a NAND gate 16, which takes their AND. As a result a modulation signal can be obtained.

Title: Cassette tape recorder
Inventor: SAIKAI TAKAO
IPC: G11B27/28
Filed: 1986-06-25
Abstract: PURPOSE:To prevent a crosstalk trouble by padding the null part of a tape position management track and a part except address data with the frequency signal of the lower limit of an audio frequency or below the audio frequency. CONSTITUTION:The frequency signal of the low limit of the audio frequency or below the audio frequency is recorded on an area 15 part by a cassette tape. For instance, if the signal of a frequency of 10Hz is recorded on the area 15, at the time of a fast feeding, a rewind searching the frequency of this area 15 becomes 200-300Hz of 20-30 times, can be completely reproduced by a reproducing head and becomes a frequency enough to detect an FM part 16 immediately after this area 15. At the time of an ordinary sound reproduction, since the frequency of the area 15 of a low frequency of 10Hz, a low cut filter can be used, and since it can not be listened to the ear of a human being even without using the low cut filter, if it enters a sound signal, the trouble does not appear actually. Thereby, the cross talk trouble to a sound track can be reduced.
