Title: Inspection device of wiring-circuit board
Inventor: KONDOU SHIYOUICHI
IPC: G01R31/02
Filed: 1991-02-27
Abstract: PURPOSE:To enable a connection resistance to be reduced and a conduction inspection accuracy to be improved by applying a conductive adhesive mass on a rear surface of a multilayer wiring-circuit board and then short-circuiting all pads on the rear surface of the multilayer wiring-circuit board electrically. CONSTITUTION:A metal (copper etc.) foil 9 with a terminal for measurement 10 is applied to a conductive adhesive mass (no metal powder etc., are mixed) 8 which is applied on a multilayer wiring-circuit board 4 and the wiring-circuit board 4 is placed on a stage 6. The terminal 10 and a probe needle 2 are connected to a resistance measuring equipment 1 and a resistance of a circuit passing a wiring pattern for I/O 3 which is connected from a rear surface of the wiring-circuit board 4 to a front surface can be measured by allowing the probe needle 2 to contact a pad 4 on a surface of the wiring-circuit board 4. By comparing the measured resistance with a desired resistance, presence or absence of conduction of the wiring pattern 3 can be judged. After conduction inspection is completed, the wiring-circuit board 4 is dipped into a supersonic washing equipment, thus enabling an adhesive mass 8 to be laminated and then dried naturally.

Title: Brass vaporizer, manufacture thereof and hot-air heater using the same
Inventor: MATSUBARA RYUJI
IPC: C22C9/04
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce high temperature creep deformation of a brass vaporizer by adding a specified amount of Sn and Cu to the brass vaporizer. SOLUTION: A brass vaporizer 1 for a hot-air heater has a liquid fuel entrance 2 at the lower center thereof and a liquid fuel exit 3 at the central portion thereof. Further, the brass vaporizer 1 is formed with a U-shaped heater fixing portion to which a heater is fixed. The brass vaporizer 1 contains 0.8-4.0 wt.%, preferably 1.5-4.0 wt.% of Sn and 57.0-62.0 wt.%, preferably 59.0-62.0 wt.% of Cu. Thus, when used in the temperature of 400-550 deg.C, the Sn concentration in a β-phase of a crystal structure can be rendered not less than 1.5 wt.%. As a result, the strength of the β-phase is improved by the solid solution of Sn to reduce the high temperature creep deformation rate. Also, in a temperature of not more than 500 deg.C, a γ-phase is deposited in the crystal structure to improve the strength, thereby reducing the high temperature creep deformation rate.

Title: Synchronizing of sampling time
Inventor: SHUDO ITSUO
IPC: H02H3/28
Filed: 1988-03-11
Abstract: PURPOSE:To decrease the number of transmission bits and to operate the transmission passage more effectively, by controlling in two stages consisting of the control of sampling time and that of sampling numbers. CONSTITUTION:First of all, the sampling time is controlled. A formula shows the sampling error  T between a main station SS1 and a slave station SS2 both necessary for the control of the sampling time. The slave station SS2 performs synchronous control over a sampling signal generation circuit of itself so that the deviation  T will be zero and is caused to follow up the sampling cycle of the main station SS1. Then the synchronous control of sampling numbers is performed. Since the synchronous signal receiving time tm to measure at the main station SS1 changes in accordance with the delay time td of the transmission passage, it counts the value td into which the delay time is expressed in the sampling time unit. The main station SS1 transmits a synchronous signal with a sampling number M0. The sampling numbers are thereby synchronized so long as the slave station SS2 controls the synchronous signal so that the sampling number of the self-station to receive the synchronous signal will always be of the value set forward by tautd as compared with M0.
