Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a fault detecting method and a fault detecting device which is more robust against an error in position/angle and realizable as easily as possible. SOLUTION: An image picking up part 12 picks up the image of an inspection object, an image inputting part 14 generates an image and an inspection image extracting part 20 extracts one or plural images at prescribed positions and with prescribed sizes in the image as an inspection image.

Title: Electronic scan antenna
Inventor: SHIRAMATSU KUNIAKI
IPC: H01Q3/26
Filed: 1984-04-19
Abstract: PURPOSE:To increase the antenna effective diameter by distributing element antennas even at inapplicable places and feeding these antennas from active modules set at places where the element antennas are thinned. CONSTITUTION:Active modules b1-bn are connected to element antennas a1-an respectively. A phase shifter is provided together with a high output amplifier, a low noise amplifier and a transmission/reception switch. A power distribution synthesizer (c) distributes the signals sent from a transmitter (e) to modules b1- bn via a duplexer (d). The reception signals of antennas a1-an are synthesized via modules b1-bn. Then the electric power is supplied to element antennas A1- AN set at places where the distribution of active modules is impossible at the back of the element antennas from active modules B1-BN of the elements that perform no transmission/reception owing to thinning via feeders l1-lN. Thus the antenna effective diameter is increased.

Title: Driving circuit for motor
Inventor: SAKIKAWA TADASHI
IPC: H02P1/22
Filed: 1980-06-13
Abstract: PURPOSE:To prevent the breakdown of a circuit by a method wherein, when control signals for normal and reverse revolution are inputted at the same time, one of the signals is cancelled. CONSTITUTION:When voltage is applied on a terminal A, transistors Q2 and Q3 are turned to ON position and a motor M revolves normally. Also, when voltage is applied to a terminal B, transistors Q1 and Q4 are turned to ON position and the motor M revolves reversely. On the other hand, when the voltage is applied to both terminals A and B, a protective transistor Q5 is turned to ON position by the aid of the voltage of the terminal A and the transistor Q4 is turned to OFF position. As a result, the motor M revolves normally in the same way when the voltage is applied to the terminal A only. Through these procedures, the breakdown of the circuit due to an erroneous handling can be prevented.

IPC: C03B11/08
Filed: 1995-04-05
Abstract: PURPOSE: To obtain a glass optical element of a high accuracy by placing a specific glass material into a mold having a thin film for preventing the fusion on a forming surface consisting essentially of silicon carbide or silicon nitride, thermally softening the glass material and press forming the softened glass material. CONSTITUTION: A forming mold having at least a forming surface comprising a material consisting essentially of silicon carbide or silicon nitride and further a thin film for preventing the fusion formed on the forming surface is used to place a glass material having <=530 deg.C transition point and <=565 deg.C yield point without containing PbO as a glass component in the forming mold. The glass material is then press formed in a thermally softened state to afford the objective glass optical element. Since the occurrence of cracking or pullout caused by glass fusion due to the oxidation of the silicon carbide or silicon nitride constituting the forming surface of the mold can remarkably be suppressed, a long life of the forming mold used is obtained and the resultant glass optical element is remarkably reduced in defects.
