Title: Manufacture of heat exchanger for vehicle
Inventor: SASAKI HAJIME
IPC: C23C2/04
Filed: 1990-03-02
Abstract: PURPOSE:To remarkably improve errosion resistance without lowering thermal conductivity and a heat radiation property by forming a predetermined pattern core with fins using copper alloy stripes and a tube and a plate plated with a Zn-based solder, and heating the core beyond the melting point of the Zn-based solder. CONSTITUTION:Copper alloy stripes are employed as a fin 1 material, and an adjacent tube 2 is plated with a Zn-based solder. A predetermined pattern core is formed with the fins, the tube, and a plate. The fins and the tube are joined by heating the core beyond a melting point of the Zn-based solder while Zn is forced to adhere to and diffuse into fin surfaces by evaporation thereof upon solder melting. For the Zn-based solder there is employed an alloy where there is added one kind or more among Al, Sn, Ag, Mn, Ni, Pb, Ti, Cu, Sb, Cr, and Mg to Zn taken as a base in the about 10% or less total amount. Upon melting the solder, a non-oxidative atmosphere is adopted, but for promotion of the Zn vaporization the condition is made a vacuum atmosphere with the degree of vacuum being 2-3Torr.

Title: Recovery system of break of power supply
Inventor: SAITOU KIYOSHI
IPC: G06F9/48
Filed: 1982-03-31
Abstract: PURPOSE:To perform correct restarting operation by allowing a next address of a processing program to be read on power supply recovery even if chattering occurs. CONSTITUTION:When a power source 1 is turned off, a power-supply on-off detection part 4 detects a fall of a voltage and outputs an off signal to a microprocessor 5. When the power source is turned on, the detection part 4 detects that and sends an on signal to the microprocessor 5. This microprocessor 5 loads a next address in a stack area of an RAM8. When the area is a power- supply break program area, a program counter stacked before it is loaded; when its value shows a normal processing program area, the state before the power source is turned off is maintained in processing. When no chattering is caused in the power-off operation, the program counter value indicating a stack point is read on power-on operation to continue the program.

Title: Controlling device for pelton wheel power plant
Inventor: NIIKURA YOSHIYUKI
IPC: F03B15/20
Filed: 1984-03-19
Abstract: PURPOSE:To eliminate the need for providing a remaining water channel, etc. and reduce cost for engineering works by making a specified selector valve an off-cam condition based on a certain rising value of frequency detected by a governor when shutting off a load in system, and shutting off flowing water only by a deflector and continuing an operation by a flow of stream. CONSTITUTION:When a load on system is shut off, a governor detects an unusual change in frequency and, when this frequency changes to exceed a certain rising value, an output signal is emitted, causing a selector valve 12 between a nozzle 2 and a needle distributing valve 9, to operate due to the output, to make a selector valve 12 an off-cam condition. Since the pressure oil of a neeld servomotor 4 is unable to move under this condition, a needle 3 has no relation with the move of the needle distributing valve 9 due to a follower cam, maintaining the needle 3 in an open state. Therefore, even if a deflector is rapidly closed, the needle 3 is left opened, allowing the flow of stream to continue. Due to the construction as stated above, it is not necessary to provide a remaining water channel and a large-capacity surge tank, sharply reducing a cost for engineering works.

In order to obtain the desired resistance value, breaks 30 are provided in one or plurality of the tape shaped resistors and trimming is achieved. In the case the resistors are manufactured so that resistance values of the tape shaped resisors 101-10n are the same (the width w and the length l are the same), the number of the resistors to be cut can be readily determined by measuring the  initial value. By combing the tape shaped resistors whose widths (resistance values)  are different, the resistance value of the resistor device 10 can be finely adjusted. In  this constitution, the current density in the tape shaped resistor can be equalized,  the breakage of wires or instability of the resistance value due to heat can be  avoided.

Filed: 1978-05-02
Abstract: PURPOSE: To tune the circuit to two types of tuning points, high and low, and to make common use the major circuit part, by providing one demodulation circuit and by changing over the tuning means with switch selection.  
     CONSTITUTION: When the switch 12 is connected to the contact 12a, the current from the DC power supply 13 flows to the diode 10, and the conduction of the diode 10 connects the variable capacitance 9 in parallel with the resonant capacitor 8. At this condition, the tuning frequency is lowered and the tuning frequency is changed by adjusting the capacitor 9. On the other hand, when the switch 12 is connected to the contact 12b, the diode 10 is inoperative. Only one resonance capacitor 8 is connected to the primary coil 7a of the tuning transformer 7, resulting in higher tuning frequency, and the tuning frequency is adjusted by adjusting the transformer 7. Thus, the provision of one demodulation circuit and the changeover of the tuning means with the selection of the switch enable the tuning of high and low types, and the major circuit 14 can be commonly used.
