Inventor: HIRAIKE FUMIAKI
IPC: G03B7/099
Filed: 1980-04-15
Abstract: PURPOSE:To check the movement of members moving at the exposure by disposing photoelectric elements in the positions where the light past a photographing lens deviates from the optical path entering the film plane so that the light entering the film plane side and the light reflected from the film plane side can be received. CONSTITUTION:Such photoelectric elements 5 and 6 by which the light entering the film plane side and the light from the film plane side can be received are disposed in the position outside the optical path of the light entering the film plane past a photographing lens 1. The outputs of these photoelectric elements B-D giving the movement information of members moving at the exposure, a diaphragm 2 and a movable mirror 3, are inputted to operational amplifier circuits F-H, which send the signals to a comparing part by receiving the output of the photoelectric element A for setting exposure conditions, so that the signal whether the movement of the moving members was accomplished or not is displayed in a display part of the operation command signal is sent to a control circuit. Thereby, the movement of the moving members is checked.

Abstract: PURPOSE: To provide a wire bonder with which the recognition accuracy of chips on a heater block is improved, the heat expansion and contraction of tool horns are prevented and the accuracy of bonding position is improved. CONSTITUTION: A cylindrical cover 21 is installed around a tool horn 15 and a capillary is projected from a lower opening 21A of the tip of it.

Abstract: PURPOSE:To provide a PWM signal generator for generating a plurality of high frequency PWM signals by performing time shared control of an adder, a comparator and a counter. CONSTITUTION:An ON width data of PWM1 signal is fetched from an 8 bit latch 3 and set in an 8 bit latch 9. A digital comparator 27. compares each corresponding bit of a free-run counter 26 up counting with a predetermined clock a and the latch 9. When each bit matches each other, a digital comparator 27 outputs '1' for inverting the output from a TFF 29 for toggle operation. An OFF width data of PWM 1 is then fetched from a latch 5 and an adder 63 adds the data to the value of the latch 9 and the sum is set in the latch 9. Similar comparison is performed again and when each bit matches, output from the TFF 29 is inverted. With regard to a PWM 2, similar operation is repeated for a latch 10 and the output from a DDF 30 is inverted.
