Title: Driving method of rolling mill
Inventor: MATSUMIYA KATSUYUKI
IPC: B21B35/00
Filed: 1982-08-05
Abstract: PURPOSE:To prevent an unevenness of driving torque undertaken by an upper and a lower work rolls, etc., by driving a work roll at one side and driving another one through a back-up roll at a peripheral speed lower than the exit speed of a material to be rolled, in a multi-roll mill. CONSTITUTION:In rolling a plate material 4 by a four high-roll mill, etc., a lower work roll 1b, for instance, is driven through a spindle 6. An upper work roll 1a is not directly driven, but an upper back-up roll 5a is driven through a spindle 8 to drive the upper work roll 1a at a roll peripheral speed VO2 equal to an exit speed V2 of a material 4 to be rolled or lower than it. Thus the distribution of rolling loads of the upper and the work rolls 1a, 1b is made unsymmetrical between them. Accordingly the problems of the unevenness of driving torque between the upper and the lower work rolls 1a, 1b, etc. are eliminated because the lower work roll 1b undertakes the rolling torque.

Title: Welding method by laser
Inventor: YAHAGI SUSUMU
IPC: B23K26/21
Filed: 1977-11-15
Abstract: PURPOSE:To carry out a good welding making control of welding easy, by shifting the laser light from the axis center of the material to be processed and enlarging welding extent. CONSTITUTION:The material to the processed 11 and the sleeve 12 are inclined about 45 against the laser light L and are support freely roratable centering around the axis center O of the material 11. Next, light axis of the light L is set parallel to X axis shifting the length l, standardizing X and Y axis making the center of the material 11 as intersecting point. Welding of joining part by laser is carried out by irradiating the light L on the weld point Q, rotating the material 11 and the sleeve 12 centering around the center O. By the above method, thickness is substantialy increased and welding extent is enlarged by increasing heat energy of the laser light. Accordingly, laser welding having a high mechanical strength, is carried out and a good welding condition is able to obtain without bringing out an accident, such as hole making etc., by abnormal heat absorption.

Title: Noise reducing circuit
Inventor: NAMIKI KOUSHIN
IPC: H03H11/04
Filed: 1984-07-02
Abstract: PURPOSE:To reduce low frequency noises without varying its sound quality by varying a low frequency component level when the output of a high-pass filter means becomes larger than the output of a low-pass filter means, and allowing the low-pass filter means to whether or not there is a low frequency signal with an enough level to mask low-frequency noises sufficiently. CONSTITUTION:A playback audio signal is supplied to a high-pass filter circuit 5, which extract high frequency signal which easily generates a low frequency noise. Consequently, the low frequency noise which can not be measured directly is detected indirectly. When the output of the high-pass filter circuit 5 is larger than the output of the low-pass filter circuit 2, a low frequency noise is easy to generate, there is no signal which masks the low frequency noise, and even when the gain of the low frequency signal is lowered, there is no large variation in sound quality. Further, when the playback audio signal has a spectrum which easily generates a low frequency noise and there is no signal component masking it, frequency characteristics of a variable filter circuit 4 are varied to lower the low frequency range.

IPC: G11C11/406
Filed: 1989-05-30
Abstract: PURPOSE:To assure the refresh of a DRAM even in a stop mode of a microcomputer and to attain an intermittent action and the reduction of the power consumption by using a system clock supply circuit which discriminates the clocks to be supplied to a CPU and a DMA controller from each other and controls the supply and its stop of the clocks. CONSTITUTION:The system clocks are divided into a clock 112 to be supplied to a CPU 104 and a clock 113 to be supplied to a DMAC 106. Both clocks 112 and 113 are kept stopped during a stop mode of a microcomputer. When a refresh request is produced to a DRAM 106, the DMA clock 113 is supplied again and then stopped when the refresh action is through. Then a clock control circuit 12 controls both clocks 112 and 113 so as to set the stop mode again. As a result, an intermittent action is attained and the power consumption can be reduced.

IPC: F16D65/28
Filed: 1977-11-17
Abstract: PURPOSE: To provide a braking system for a brake motor, which system utilizes the pressing force of the brake and the reaction force of the releasing force thereof.  
     CONSTITUTION: When a current is carried to a motor, a rotor 27 revolves, and simultaneously the current is carried to an electromagnet 12, and a lever 14 pulls a frame 19 to the right side by the attraction of an electromagnet 13. Simultaneously, since the lever 14 pulls a mounting shaft 16 to the left side, friction material 21 and 21' are separated from a friction disc 22 thereby to make the revolution of the disc 22 free. Then, when the current is shut off, the attraction of the electromagnet 13 is released, and hence the lever 14 presses the mounting shaft 16 to the right side with a pin 30 as a fulcrum, thus the friction material 21 being pressed against the disc 22. Simultaneously, since the pin 30 is forced to the left side to pull the frame 19 to the left side, the friction material 21' mounted thereon is pressed against the friction disc 22 to stop the rotation of the friction desc 22.

CONSTITUTION:A fuel gas recirculation line 9 is provided so that it extends from an outgoing fuel gas line for a fuel cell 4 to an incoming fuel gas line therefor. A blower 10 for causing an outgoing fuel gas to flow through the circulation line 9 and a valve 11 for regulating the flow rate of the outgoing fuel gas through the line 9 are used so that the loss of the pressure of the fuel gas in the fuel cell 4 is measured by a pressure difference meter 12. A controlling indicator 13 performs control while the recirculated quantity of the outgoing fuel gas is detected by a flow meter 14, to keep the pressure loss at an aimed level. In the algorism of the controlling indicator 13, an aimed level for the recirculation flow rate of the fuel gas is determined by proportional integration on the basis of the difference between the aimed level for the pressure loss and the measured value thereof, and the degree of opening of the recirculation flow rate regulating valve 11 is determined by proportional integration on the basis of the difference between the aimed level for the recirculation flow rate and the measured value thereof and then applied to the valve. The pressure loss of the fuel gas in a fuel cell stack is thus always kept not lower than a prescribed level, to equalize the fuel flows in the fuel cells of the stack to each other.
