Patent JP-H05291911-A (JP)
Title: Reset circuit
Inventor: SAKIHAMA KAZUHISA
IPC: H03K5/13
Filed: 1992-04-14
Abstract: PURPOSE:To prevent malfunction of an internal LSI by turning on complementarily two MOSFETs based on an input signal so as to send the signal while eliminating chattering. CONSTITUTION:When a level of an external reset terminal 5 is set from an L to an H after lapse of a sufficient time after application of power, a P- channel MOS TR 2 is turned off and an N-channel MOS TR 12 is turned on. As a result, a potential at a node 10 falls down quickly, an output signal of an inverter 4 goes to an H level to activate a signal fed to an internal LSI. When the level of the signal at the terminal 5 is set to an L, the FET 2 is turned on and the FET 12 is turned off. When a potential of the node 10 exceeds an input threshold level of the inverter 4, an output signal of the inverter 4 changes from H to L. Thus, the output signal of the inverter 4 responds to a rise time of an external reset signal at a high speed and to a fall time of the signal very slowly and any chattering is eliminated from an output of the inverter 4 even when the signal at the terminal 5 includes any chattering.

Title: Optical scanner
Inventor: BURUUSU REIMONDO HOWAITEINGU
IPC: G02B27/00
Filed: 1993-04-21
Abstract: PURPOSE: To minimize the interference between a directly transmitted scanning light beam and light reflected back inward by the exit face of a medium by most suitably adjusting movement paths of the beam and the medium. CONSTITUTION: A light beam forming system 18 generates a light beam which has an elliptic section having a major axis and a minor axis. A scanner 20 deflects the light beam 50 at a prescribed flat scanning angle in the scanning direction of a scanning line on an incidence face 68. A film medium 24 is so moved that the scanning light beam is scanned as a continuous line on the medium. The film medium 24 is inclined at a certain angle to the horizontal scanning angle of the deflected light beam 50, and the interference between incident light and reflected light from the exit face is minimized at all points of the light beam 50 deflected at the horizontal scanning angle.  When the light beam whose section is expanded to an ellipse is rotated in the cross scanning direction of the film medium, a smaller angle of inclination is required in comparison with a beam having a circular section or a non-rotated elliptic beam, and it is effective furthermore.

Title: Semiconductor light emitting element
Inventor: NAKAMURA MASARU
IPC: H01S5/00
Filed: 1981-06-19
Abstract: PURPOSE:To protect a semiconductor light emitting element body against an excessively high input by flowing most of a current through another P-N junction which does not contribute to the light emission at the abnormal time (at the time of excessively high input). CONSTITUTION:A P-N junction 13 to become a light emitting region is formed between an N type GaAs layer 11 (a first semiconductor crystalline layer)and a P type GaAs layer 12 (a second semiconductor crystalline layer), an N type GaAlAs layer 14 (a third semiconductor crystalline layer) is formed, and the P-N junction having large junction area and high barrier potential difference is formed between the layers 12 and 14. Thus, most of the applied current flows through a P-N junction 15 against the excessively high input, but least amount of the current flows through the junction 13 which contributes to the light emission. At this time, a high resistance layer 17 produces a voltage drop when the output impedance of an excessively high input source is low, thereby operating so as not to apply the excessively high voltage to the junction 13.
