Abstract: PURPOSE:To enable to stably connect a semiconductor package, wherein the pitch among terminals is short and numerous pins have been used, to a printed substrate by soldering without needing a high-degree work by a method wherein the semiconductor package is mounted on the printed substrate and the terminal parts thereof are heated. CONSTITUTION:Plate-type solders 6 and 7 are bonded respectively one sheet by one sheet to each of the connection surfaces of terminals 2 and 3 on both sides of a semiconductor package 1 through soldering fluxes 4 and 5 respectively. Then, the plate-type solders 6 and 7 are isolated by being cut into individual solder pieces 6' and 7' using a metal mold, etc. At this time, nearly a constant amount of solder is contrived to be left on each of the termianals 2 and 3. The semiconductor package 1 processed in such a way is mounted on a printed substrate 8, and after that, the terminals 2 and 3 are heated by a soldering iron, a laser, etc., and the terminals 2 and 3 are made a soldered joint to the printed substrate 8. As a result, as long as the thickness of the plate-type solders, etc., have been managed, the amount of solder to be supplied to each terminal can be controlled constant, thereby enabling to stably connect the terminals to the printed substrate.

The output signal of the subtracter 14 is therefore the signal sent from the amplifier 4 and sent to a DC amplifier 15 and a display circuit 16, which displays it. When a calibration mode is entered, on the other hand, a relay 9 or 10 is operated with the signal of a mode switch 12 and the signal of a calibration signal generator 7 or 8 if superposed upon the signal from the detector 1. The signal of this switch 12 is sent to the circuit 13 at the same time and the signal of circuit 13 is sent to the subtracter 14 and subtracted from the signal sent from the amplifier 4; and the subtraction result signal is sent to an amplifier 15 and the circuit 16 and the value obtained with the calibration signal is displayed.

Abstract: PURPOSE: To prevent the slip of tires at quick acceleration by quickening the rise up of an accelerator command voltage upto a certain value by the conducting-rate detection in soft start characteristics, then, giving the linear delay characteristic.  
     CONSTITUTION: When the accelerator 17 is fully opened in the starting on the flat ground, the chopper conducting rate (the conducting rate at which the car starts) is detected, a transistor TR 3  is in the conductive state during the time the output of an operation amplifier 26 is Low, and the voltage of a capacitor C 1  rises up quickly. Thereafter, the conductive rate increases, the output of the amplifier 26 becomes H, the transistor TR 3  becomes nonconductive, and the first delay characteristic is obtained with the time constant formed by resistors R 1  and R 2  and capacitor C 1 . Therefore, the accelerator command current I c  flowing in the acceleration command winding 22 varies similarly. The output waveform of a magnetic phase shifter varies depending on the increase in the current I c , a chopper circuit 14 repeats the conduction and nonconduction by a trigger circuit 24, the average voltage to be applied to the motor is varied, thereby the motor speed is conrolled.

Abstract: PURPOSE:To start arcing in a satisfactory condition free from deposition and scattering in pulsed arc welding with a consumable electrode by inputting the electric power in the arc start period with higher pulse current in shorter time so as to have the same value as the average value of welding current. CONSTITUTION:A command circuit 1 commands a base current power source BPS, a wire feed circuit WF and a pulse current control circuit 3 to start welding upon turning on of a welding start switch PB1 and at the same time a pulse current switch circuit 2 passes the pulse current which has a high pulse current value, short duration time and the same value as the average value of the welding current by the instruction from a start pulse setting circuit 7. A time limiting circuit TM is actuated by the detection DT for starting welding and after a specified time, a pulse signal switch circuit SW switches a pulse setting circuit 8 during welding to continue welding. Since the start input has the same value as the value of the input during welding, the sure arc starting is accomplished without deposition and scattering by melting of the electrode chip.

A CPU 2 receives this signal to issue a dot density control signal DPIC to a dividing circuit 5. In the dividing circuit 5, an FG pulse issued from a polygon motor M2 is divided to be outputted to a polygon motor drive circuit 4. At this time, the dot density control signal DPIC changes a dividing ratio. during a period of time after the completion of image forming before the ON operation of a next print signal PRINT, the CPU 2 changes over the DPIC signal immediately after the DPI signal is changed over to change over the number of revolution of the polygon motor M2.

Title: Method for changing control program for facsimile equipment
Inventor: IKUTOMO TOKUO
IPC: G06F13/00
Filed: 1992-05-07
Abstract: PURPOSE:To dispense with the work requiring manual aid by using a rewritable storage medium as a storage and sending and storing a control program through a communication line. CONSTITUTION:A rewritable storage medium is used as a storage part (hard disk) 8 to store a control program sent through a communication line B. The storage part 8 stores a microprogram in its one part area 8a, and stores an update microprogram for rewriting in its other part area 8b. A facsimile equipment A stores picture data read by a reading section 3 temporarily in a picture memory 5 at the time of transmission. A control section 1 compresses the picture data to send it to the destination device A from a line section 2. At the time of reception, the control section 1 expands the picture data to output the result from a recording section 4. The control for these is performed by the control program stored in the area 8a, and when a memory 5 is changed, the program can be changed, resulting in dispensing with the work requiring time and manual aid.
