Title: Heat treatment for metal matrix composite material
Inventor: KOBAYASHI TOSHIRO
IPC: C22C47/00
Filed: 1993-02-19
Abstract: PURPOSE:To relieve thermal stress and to increase the strength of a metal matrix composite material as a whole by performing cooling treatment down to a specific temp. at the time of heat treatment of a metal matrix composite material. CONSTITUTION:A process, where cooling is done down to low temp. at least once, is added to the heat treatment process for a metal matrix composite material where metal (alloy) is used as matrix and ceramics and metal are used as reinforcement. It is preferable to regulate the cooling temp. to <=0 deg.C. Because thermal stress is relieved by the cooling, a crystallographical dislocation is generated in the matrix of the metal matrix composite material and the matrix is strengthened, and consequently, the whole metal matrix composite material is also strengthened and superior strength characteristics can be obtained. In this cooling process, the rate of change in temp. in a cooling stage down to a specific temp. is made dissimilar to that in a subsequent temp. rise stage, by which dislocation density increased by cooling is moved in the direction of dislocation source in the temp. rise stage to prevent the dissipation of the dislocation density in the interface between the reinforcement and the matrix.

Title: Signal transmission equipment
Inventor: IWASAKI YOSHIHIRO
IPC: H04Q9/00
Filed: 1986-02-14
Abstract: PURPOSE:To prevent the effect of high voltage noise and to protect the inside of a controller from a burn-out fault even when a transmission line is connected wrongly by connecting an overvoltage absorbing circuit to the transmission line and disconnecting the transmission line when an overvoltage takes place in the transmission line. CONSTITUTION:A switching element 29 is driven in response to a transmission data and a data is sent to an opposite controller through transmission lines 23, 24. Further, a data signal from the opposite controller is inputted via a photocoupler 27 and inputted to an electronic circuit in the inside of the controller and since a varister 25 is connected to the transmission line 24 is such a case, the overvoltage over the critical voltage of the varister 25 is not applied to the inside of the controller. Thus, burn-out of an electronic circuit in the inside of the controller is prevented. Further, if an overvoltage is fed to the transmission lines 23, 24 due to mis-wiring, a large current flows to the circuit of the varister 25, a fuse 26 is blown by the current and the controller is disconnected from the transmission lines 23, 24 being a cause to the application of overvoltage.

Abstract: PURPOSE:To obtain an excellent read signal by providing MR elements which are symmetrical above and below a yoke while they are equipped with center taps, supplying signal magnetic flux which is led out of the yoke to both the MR elements equally, and canceling higher harmonics of even order of a differential amplification output signal. CONSTITUTION:On a ferromagnetic material substrate 9 of Mn-Zn ferrite, etc., an MR element 4 is formed of Ni or Fe alloy and on the element, a bias wire and yokes 1 and 2 made of ferromagnetic bodies are formed across an electric insulating layer. The tip of the yoke 1 forms a gap 10 and an MR element 3 is formed on the yokes 1 and 2 and bias wire 5 across the insulating layer. Thus, the MR heads which are formed equally pick up signal magnetic flux from the magnetic body in a gap 6 and the magnetic flux is transmitted to the MRs 4 and 3 through the yoke 1. The magnetism of the both elements is biased with a bias current flowing to the bias line 5 positioned between the elements 3 and 4 so that the magnetism slants as about 45 deg.. Then the magnetism in the elements 3 and 4 is rotated with a DC sense current 12 and changes into resistance, which is sent to a differential amplifier to cancel the higher harmonics of even order.

Title: Fluid pressure clutch
Inventor: ISHIMARU TETSUTOKI
IPC: F16D48/02
Filed: 1979-03-19
Abstract: PURPOSE:To raise the clutch joining performance by canceling the piston pushing pressure caused by the centrifugal force at the time of rotation, which works on the staying working fluid. CONSTITUTION:The working fluid from the oil passages 22, 23 is constantly filled up in the fluid pressure chambers 15, 16. In case a shaft 19 rotates in this state, the  working fluid filled up and staying in the fluid pressure chambers 15, 16 receives the centrifugal force to work on the receiving surfaces 2, 3 of the piston 2 as the pushing pressure. This pushing pressure works each other as the tensileforce of the rod 4 after all to cancel the pushing pressure working on the receiving surfaces of both pistons meaning practically that the centrifugal fluid pressure caused by the rotation of the shaft 19 does not act on the receiving surfaces of the pistons of the fluid  chambers 15, 16. Accordingly it results in the improved clutch cut, improved fluid  pressure control responsibility, raised clutch joining performance, prolonged clutch lifetime and the raised driving safety.

Abstract: PURPOSE: To simplify the control circuit with such an arrangement for effecting current control of an inductance load with a semiconductor element by using a terminal voltage across a resistor as a feedback signal and driving an operational amplifier with positive and negative voltages on zener diodes as control voltage source.  
     CONSTITUTION: For controlling current flowing in a load 3 to a constant current with a transistor 4, constant voltage diodes 16 and 17 are connected in the same polarity orientation and in series with each otherbetween DC bus bars, with the positive voltage side of the juncture between the constant voltage diodes supplied as positive voltage source and the negative voltage side as negative voltage to an operational amplifier 10. Further, the negative current is detected as voltage drop across a current detection resistor 18 and supplied to the operational amplifier 10. Thus, the operational amplifier 10 compares the output voltage of a current setter 11 and a terminal voltage across a current  detection resistor 18, so that the current is controlled to a constant value determined by a current setter 11. In this way, it is possible to dispense with an independent power source or a current transformer and thus simplify the circuit.
