Title: Amplifier circuit for switching gain
Inventor: MURAKAMI MITSURU
IPC: H03G1/00
Filed: 1982-05-13
Abstract: PURPOSE:To fix an operating point by connecting an amplifier with common load and constant current source when selecting amplifiers with different gain in case of necessity. CONSTITUTION:A VHS type VTR in an NTSC system doubles a color burst signal at recording and halves the burst signal at reproduction. In a color signal processing circuit, differential amplifiers 19, 21 having low gain are connected in parallel through differential amplifers 20, 22 having high gain and switching transistors 23, 24 respectively. Since the common load and constant current source can be used at the operation of each differential amplifier, the DC potential of an output signal can be prevented from variation at the switching of the amplifier.

Title: Proportional solenoid valve drive output correcting device
Inventor: TAMAI SEISHIN
IPC: F16K31/06
Filed: 1989-03-31
Abstract: PURPOSE:To make the oil pressure constant by allowing a CPU to sense the current value flowing through a proportional solenoid valve fitted on the transmission of an agricultural working vehicle, comparing the output therefrom with a reference value specified for the solenoid valve, and correcting the output On time due to pulse width modulation either to Long or Short. CONSTITUTION:By a transistor circuit 2 in connection with a CPU 3, the output current flowing through a solenoid 22 is supplied restrictedly with the output On time in the output periods due to pulse width modulation to be controlled by interrupt processing of the CPU 3. Immediately before each output time goes out, the output current value is sensed by a calculational amplifier 23 and sent to the CPU 3. The CPU 3 compares it with a reference current value for the pre-registered output On time. According to the result therefrom an output On time correcting circuit A makes correction so that the output On time becomes shorter when the lubricant temp. in the transmission concerned 6 at starting of the work is low and when the current value flowing through the solenoid 22 is large. This enables maintaining the oil pressure constant at all times regardless of the current value flowing through the solenoid 22.

Title: Resistance diffusion joining method
Inventor: INOUE SHINICHIRO
IPC: B23K3/04
Filed: 1993-04-08
Abstract: PURPOSE:To prevent occurrence of peeling at a joining surface after heat treatment by interposing a copper alloy intermediate layer softer than a copper alloy member between a copper alloy member and steel member. CONSTITUTION:A 75 Cu-25 Zn plating layer 2 of 20mum thickness is formed on the surface of a steel member 1, placing a brazing filler metal 3 thereon and a copper alloy intermediate layer 4 of 0.5mm, this is sandwiched by Ag-W electrode to be pressed and energized. After joining the intermediate layer 4, a brazing filler metal 5 is placed on the intermediate layer 4, further a copper alloy sliding member 6 is placed thereon to be pressed and energized, obtaining the required joining member. As a result, as the copper alloy intermediate layer 4 of 0.2 proof stress of <30kgf/mm is sandwiched between a steel member 1 and copper alloy sliding member 6 of 0.2 proof stress >=30kgf/mm, after joining and heat treatment, peeling of the joined part does not cause. By this method, the occurrence of peeling at the joined surface after heat treatment is prevented.

Title: Suspension bridge
Inventor: HIGAMI YUUICHI
IPC: E01D11/00
Filed: 1992-04-03
Abstract: PURPOSE:To prevent the torsional deformation of a bridge girder by positioning the connecting section of a hanger on the horizontal extension of an aerodynamic center to a side wind of the bridge girder when the bridge girder is hung down by the hanger. CONSTITUTION:When a bridge girder 5 receives a side wind W, the force of the side wind works to the aerodynamic center A of the bridge girder 5, and is transmitted linearly over hanger connecting sections 4a positioned on the horizontal extension 7 of the aerodynamic center A. Consequently, no couple of forces is generated in the bridge girder 5, thus preventing the torsional deformation of the bridge girder 5 based on the side wind W. Since torsional deformation is inhibited, a flutter is difficult to be generated. Accordingly, allowance can be acquired regarding wind resistance, the degree of freedom at the time of a design is improved, and the bridge girder 5 can be lightened.

IPC: B23K9/12
Filed: 1998-03-13
Abstract: PROBLEM TO BE SOLVED: To provide the feeding device for the welding wire, by which weld quality by electric welding can be improved. SOLUTION: The wire W drawn out from a wire drum 10, is wound in the state of a mono-layer on the outer peripheral surface of a forming drum 30. By this operation, since the wire W is almost uniformly heated by an outer peripheral plate 36 by high frequency induction heating, even when the fluctuation (dmax→dmin) of the winding diameter of the wire W, occurs by the fact that the wire W is wound in a multilayer state, a curve with a prescribed curvature by the prescribed outside diameter D of the outer peripheral plate 36, is given to the wire Wb. Consequently, even the wire W wound in the multilayer state on the wire drum 10, since the curve with the prescribed curvature by the forming drum 30, is given to the wire We fed from a wire nozzle 22, the tip part of the wire for the welding, can be positioned with high precision near a welding electrode 12.

Abstract: PURPOSE:To generate an image signal which is progressive scanning and has doubled frame frequency from an interlacing scanning image signal by reading the image signal for each one horizontal scanning alternatively from each memory at doubled speed than recording. CONSTITUTION:After installing a magnetic disc 1 in a reproducing machine, the track of the external circumference side is scanned with one magnetic head 3A and the track of the internal circumference side is scanned with another magnetic head 3B simultaneously with the magnetic disc 1 rotated at 60rps.

The memory 5A and 5B are constituted so that they read an input signal for each one horizontal scanning at doubled speed than recording. A switch 6 selects output of memory 5A and 5B alternatively for each 31.7mus. Thus, the output 17 from the switch 6 is the image signal which is progressive scanning and has frame frequency of 60 cycles per second.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of positional displacement in a nozzle device and a flow control valve even when instantaneous service interruption is generated during the operation of the nozzle device and the flow control valve. SOLUTION: The generation of instantaneous service interruption is decided when the next zero cross signal is not input even after the passage of a first setting time tS after the input of a last zero cross signal to a controller 21, and each motor 4c, 5d driving a nozzle device and a flow control valve is stopped while the recovery of instantaneous service interruption is judged when the zero cross signal is input again before the passage of a second setting time tR after the stoppage of the motors 4c, 5d, and the nozzle device and the flow control valve are reworked from the state before the stoppage of the motors 4c, 5d by re-driving the motors 4c, 5d.  When the zero cross signal is not input even after the passage of the second setting time tR, the controller 21 is reset, the nozzle device and the flow control valve are returned to the place of an origin once after the recovery of instantaneous service interruption, and the nozzle device and the flow control valve are operated again.
