Title: Protection system for generator equipment
Inventor: YAMAMOTO KAZUHIRO
IPC: H02H3/16
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To obtain a protection system of generator equipment, which can stop a failed generator using only ground overcurrent relays. SOLUTION: An AND gate GATE1 decides whether a generator G1 whose neutral is grounded is in operation from a breaker 52G1 and a neutral switch 42G1 of the generator G1. AND gates GATE2-GATE4 output the trip commands of other generators G2-G4, when a ground overcurrent relay 51GG1 of the generator G1 with the grounded neutral, ground overcurrent relays 51GG2-51GG4 of the respective other generators G2-G4 and the ground overcurrent relay 51GG0 are in operation. A timer T1 outputs the trip command of the generator G1 with the grounded neutral, when the ground overcurrent relay 51GG0 operates continuously for a period longer than a predetermined time.

Abstract: PURPOSE:To control the quantity of the extension of a lens at a high speed by installing a light emitting element at a position equivalent to an image pickup surface, irradiating an object with spot light through an image pickup lens, and forming an image of its reflected light on the image pickup surface through the same lens. CONSTITUTION:Light from the light emitting element 6 at a position equivalent to a point on the lens optical axis of the image pickup surface 3 passes through an aperture 5 and is reflected partially by a half-mirror 4 to illuminate the object 1 through a part E off the center part of the image pickup lens 2. The reflected light from the object 1 forms an image on the image pickup surface 3 through the lens 2 and half-mirror 4. When the object 1 is at the position shown by a solid line, the image of the light source 6 is formed on the optical axis of the lens 2, so its reflected light forms the image on the lens optical axis of the center part of the image pickup surface 3. The light from the light source 6 is irradiated as spot light above the object when the object is positioned as shown by a dotted line 1' or below the object when the object is as shown by a dotted line 1'', and the center of the reflected light from the object is therefore incident on the lower part and upper part on the image pickup surface 3 respectively.

Abstract: PURPOSE: To improve focus characteristics in the whole current amount area of an electron beam with a simple structure so as to obtain excellent resolution, and reduce moire in a small current area by forming a fixed non-uniform electric field in a deflection magnetic field so as to compensate the deflection of the electron beam.

Thereby, focus characteristics in the whole current area of the electron beam are heighten without applying a dynamic focus voltage so as to improve resolution, and also the occurrence of moire in a small current area can be suppressed.

Title: Mos field effect type semiconductor circuit device
Inventor: TAKEI HIDEKI
IPC: H02H7/20
Filed: 1980-12-27
Abstract: PURPOSE:To make a P-N junction diode for prevention of destruction provided in an MOS field effect type semiconductor circuit device to be used both as a field film destruction prevention element by a method wherein the P-N junction diode for prevention of destruction is provided in parallel with a resistor circuit for prevention of destruction connected in series to a gate, and the diode thereof is arranged at the lower part of the field insulating film in a pad region. CONSTITUTION:A P type diffusion layer 7 is provided at the lower part of a field insulating film 2 at the lower part of an input/output terminal 1 to constitute a P-N junction diode for prevention of destruction, and a terminal 5 is provided to constitute also a resistor for prevention of destruction. Accordingly when an abnormal voltage is applied to the input/output terminal, the forward directional or the reverse directional current path of the diode is formed to perform protective action, and a voltage generated during the delay time of operation of the diode is not applied directly to a gate film owing to action of the resistor. Therefore because electric potential difference between the input/output terminal and the substrate at the lower part of the field film is eliminated, destruction of the field film is not generated, and effective utilization of the substrate at the lower part of the pad can be attained to enhance integration.
