Title: Laser working device
Inventor: KUWABARA KOUJI
IPC: B23K26/08
Filed: 1982-10-27
Abstract: PURPOSE:To enable punching operation by plural pulses and to punch a thick material at a high speed by controlling the moving speed of laser light on a work and the moving speed of the work at the same speed. CONSTITUTION:The laser light 2 from a laser light generator 1 is reflected by an oscillating plane mirror 3, and is condensed by a condenser lens 4 so as to be irradiated to the working point 8 on a work 5. Since the mirror 3 is rotated in an arrow direction 7 around a fulcrum 6, the point 8 moves in an arrow direction 9. On the other hand, the work 5 on a moving table 10 is likewise moved in the arrow direction 9 by a driving device 11. If the moving speed of the point 8 is made to coincide with the moving speed of a moving carriage 10, the laser light 2 is irradiated to the same spot on the work 5. A punching operation for one hole is thus made possible by plural pulses without stopping the work 5.

Title: Nonimpact printer
Inventor: SENSUI KIYOSHI
IPC: G06K15/12
Filed: 1980-12-26
Abstract: PURPOSE:To enhance reliability of a printing result to a great extent, by using a mechanism for detecting surface potential of a photoconductive drum together with an abnormal state detection mechanism based on the conventional mark reading. CONSTITUTION:A photoconductive drum 7 is charged to +V1 on the part A by applying positive charge from a high voltage corona charger 1. Upon irradiation of laser beams the potentials on the irradiated parts drop about to a standard level 0V. In an electrophotographic mechanism 3, toner charged to +V2 attches onto the parts irradiated with the laser beams, that is, the places of 0V, and the attached toner is transferred onto a printing paper 6 with a corona charger 5 for transfer having -V5. When the charger 1 gets out of order and positive charge is not given, the surface potential on the part C become +V2, and when an excessive amount of toner attaches to the drum surface on account of trouble of the electrophotographic mechanism 3, the surface potential of the part C becomes +V3. Therefore, detection of the surface potential of the photoconductive drum corresponding to this region unsuitable for printing permits trouble of each part to be detected.

Title: Sense amplifier
Inventor: KACHI YOSHIO
IPC: G11C11/34
Filed: 1982-10-27
Abstract: PURPOSE:To obtain a high speed as well as a wide dynamic range and at the same time to ensure a latching function by using two differential sense amplifiers and applying a positive feedback between these two sense amplifiers. CONSTITUTION:It is supposed that digit lines D and D' are precharged. In such a case, the potential of an output terminal O is decided by the ON resistance ratio between a PchMOSFET11 and NchMOSFET13 and 15. So is with a terminal O'. Here NchMOSFET25 and 15 function as constant current sources respectively. If an address is selected and a difference of potential is produced between lines D and D', either one of these two lines is changed to a high level with the other changed to a low level respectively. The sensitivity of a sense amplifier is increased since the working points of both FET15 and 25 are at a saturated region. In such a way, a positive feedback is applied to two differential amplifiers to invert the output at a high speed.
