Title: Image display device
Inventor: MATOBA HIROSHI
IPC: G06T1/60
Filed: 1990-01-23
Abstract: PURPOSE:To give an effective function to an application field wherein high speed and accurate drawing processing is required by enabling a dual-port RAM to control information power from a serial port with a serial clock. CONSTITUTION:For a X1 display, a value whose bits assigned to the serial-out clock of a latch 2 repeat 1 and 0 in set in a register 4 at a period required for the X1display by the dual-port RAM 7. This value T is found by determining the assigned bits of an input to the serial-out clock of the RAM 7, a clock period, the numbers of bits of a latch 2, registers 3 and 4, and an adder 5, etc. For X2 enlargement, when the value of the register 3 is denoted as T/2, the increment of the latch 2 which increases with each clock becomes 1/2 and the serial-out issue decreases to a 1/2 frequency. Consequently, the application field where the high speed and accurate drawing processing is required is given the effective function.

IPC: H01L21/52
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to prevent pellet from peeling off even if a small pellet size is used by gradually increasing heating temperature, and, when the temperature reaches the peak, reducing it. SOLUTION: The temperature profile for the method for the manufacture of semiconductor devices is as follows: To reach the first zone, temperature is increased to 150 deg.C in 0.02 minutes, and the temperature is maintained for 0.5 minutes till the second zone. Subsequently, heating is performed at 150 deg.C for 0.5 minutes in the third zone and fourth zone, and at 200 deg.C for 1.0 minute in the fifth through eighth zones, and then the temperature is reduced to 25 deg.C in 0.25 minutes. As mentioned above, the heating temperature is increased, and when the peak is reached, it is reduced. Thereby semiconductor pellets can be protected against abrupt temperature rise, and reduction in bonding temperature can be prevented.  Further, by lengthening the time it takes to increase heating temperature, thermal decomposition of Ag paste can be more effectively prevented, and bonding failure can be prevented.

Abstract: PURPOSE:To save the power consumption of a driving transistor in a step motor driving circuit by reducing the feedback resistance value of a resistor connected between the input and the output of the standard voltage of a comparator for comparing the current detecting voltage of phase windings of a step motor with the standard voltage at overdrive time. CONSTITUTION:A transistor T1 is conducted by applying a drive pulse DP thereto to flow a current through phase winding 1. The winding current is detected by a detecting resistor RI, and compared with a standard voltage Vr by a comparator 2. While the winding current detecting voltage is lower than the voltage Vr, the output of the comparator 2 is high level to conduct a transistor T2. When both voltage become equal, the output of the comparator 2 becomes low level to turn the transistor T2 off. There is relationship of Rf1>Rf2 between the feedback resistors Rf1 and Rf2. When the motor is stopped, the resistor Rf1 is connected to shorten the output inverting period of the comparator 2. When the motor is overdriven, the resistor Rf2 is connected to lengthen the output inverting period.
