Patent JP-H03166739-A (JP)
Title: Method for soldering
Inventor: SUTEFUAN PIIITAA RETSUGU
IPC: H05K3/34
Filed: 1990-10-02
Abstract: PURPOSE: To execute soldering at a low temperature, in which adhesive is not deteriorated by immersing pads on a substrate with eutectic alloy and executing solder plating or executing coating. CONSTITUTION: Fitting is executed by the mutual operation of solder and eutectic alloy lower than the melting point of solder. Namely, coating is executed in a range with which solder balls 7 of the substrate are brought into contact by an alloy of 63% of tin and 37% of lead, and a chip 1 is arranged on the substrate. Then, the solder balls 7 are arranged with alloy pads 9. When the temperature of the device is raised to the melting point of the alloy by using a thermoid 10, pad alloy 9 becomes a melting state. Since the solder balls 7 have miscibility with respect to the melting alloy 9, the materials of the solder balls 7 melt into the melting alloy 9, a continuous change occurs in the composition of the melting mixture, and the melting point rises.  When the compositor of the melting mixture becomes out of eutectic composition, the melting point reaches a temperature at which the melting mixture is solidified, and the junction is completed. Thus, the temperature by which fitting can be executed can be lowered.

Title: Control device for vehicle
Inventor: HATTORI TOSHIHIRO
IPC: F16H59/08
Filed: 1985-11-22
Abstract: PURPOSE:To reliably accomplish gear parking by generating a select signal to an electronic control device by selection of parking position, and performing gear speed change after a key switch is turned off. CONSTITUTION:When a selector lever 7 is switched to P-range, X signal is input to a control device 9 by action of the respective X contacts of ON switch of a selector switch 7a and B switch to judge whether the gear position of a speed change gear 6 is first speed or not. If it is a gear position other than the first speed, a command is given to an actuator 5 to shift the gear position to the first speed. Even if a key switch is OFF, the operation is retained, with a main relay connected for a designated time by inputting X signal to the control device 9. Accordingly, after the key switch is turned off, the gear is reliably forced to enter a speed change step with a large speed change ratio by operation of the selector lever after the lapse of time, so that gear parking can be accomplished in case of slope parking.

Abstract: PURPOSE:To reduce power consumption while maintaining the speeding-up properties of the speed of response by using a first power supply having high voltage when a solenoid is driven and flowing holding currents through the solenoid by employing a second power supply lower than the first power supply after the solenoid is operated once. CONSTITUTION:When a driving signal D is transmitted, Tr1-Tr3 are all turned ON, currents flow through a first power supply E1, the transistor Tr2, a solenoid L, R, the transistor Tr1 and a resistor RS, and currents flowing through the solenoid rapidly increase.

Currents gradually reduce owing to a resistance section made to be contained in the solenoid, a current value finally reach E2/R (where RS is neglected because of a small value), and only the holding currents of the solenoid flow.
