Title: Detector of discontinuity in heated transparent element with improved reliability
Inventor: HARII SHIEAA KUUNTSU
IPC: B32B17/10
Filed: 1989-01-13
Abstract: PURPOSE: To find discontinuity existing in either position of a heating circuit being conveyed on a transparent body containing coating by applying electric power to transparent bodies existing in different two regions, and measuring the difference of voltages in the two regions. CONSTITUTION: A conductive coating 13 is placed on the inner side of an outer glass plate 10, and a bottom bus bar 15 and a top bus bar 16 come in contact with the coating 13. Lead wires 23, 24 of a voltage sensor are extended from a terminal region 22 in parallel to bottom extending belt plates 20, 21 and come in contact with the end of the bottom bus bar 15, and the conductive coating 13 is divided into two separate circuits by a discontinuous part 30 in the top bus bar 16. The lead wires 23, 24 of the voltage sensor are connected to a comparator 31 with lead wires 32, 33, reference voltage is supplied to the comparator 31 with a lead wire 34 from a power supply 25, voltage between the lead wires 32, 34 is compared with voltage between the lead wires 33, 34. A trouble on one side of a heating circuit is detected.

Title: Steering system for outboard motor
Inventor: MATSUMOTO OSAMU
IPC: B63H25/42
Filed: 1989-01-11
Abstract: PURPOSE:To keep off any missteering due to inertia force at time of sudden starting by forming each damper chamber being interconnected by a throttle hole at both ends in the sliding direction of a sliding member to be slid by crosswise rocking operation of an outboard motor. CONSTITUTION:When an outboard motor body 7 receives rocking force in both directions as a whole by starting force of an engine 11, a pivot shaft 5 tries to rotate in the same direction with this rocking motion. With this, a screw piston 16 moves up and down by an external thread 18. With this vertical motion, oil in a damper chamber 21 at the upper side or the lower side is moved to the damper chamber 21 at the opposite side by way of a throttle hole 22. A damper effect is produced by resistance of the throttle hole 22 at this time, thus rocking motion in the outboard motor body is checkable. With this constitution, any missteering due to inertia force at time of sudden starting or the like is thus preventable.
Patent JP-H05190322-A (JP)
Title: Load drive circuit
Inventor: SAKAI MASAYOSHI
IPC: H01F7/18
Filed: 1992-01-14
Abstract: PURPOSE:To reduce the delay of the load operation stop in a drive circuit for an inductive load. CONSTITUTION:When a load 4 is actuated, rectified outputs V1 and V2 are produced and a high voltage obtained by summing both outputs is supplied to the load 4. When a specified time has passed after the actuation, the output from a differentiating circuit 6 is stopped and consequently, the rectified output V2 is also stopped; the load 4 is kept operating on a low voltage originating only from the rectified output V1. When the load drive is stopped, therefore, the energy stored in the load 4 is lower than the conventional, which reduces the delay of the operation stop. Inserting a Zener diode into a load feed circuit can further reduce the delay of the operation stop.

Title: Automatic focusing device of video camera
Inventor: URATA SHINJI
IPC: G02B7/36
Filed: 1982-01-19
Abstract: PURPOSE:To make a photographic lens irrelevant to driving relation in focusing by varying the distance between a lens fitting part and an image pickup surface by a foucing detection signal. CONSTITUTION:Light of subject to be photographed passed through the photographic lens 14 is split and guided to an image pickup device 7 and a focusing detector 9. According to a focusing state, the detector 9 outputs a detection signal through a signal processing circuit 10. When the detection signal does not show a focusing state, a motor driving circuit 11 operates to drive a motor M and then the lens fitting part 15a moves to vary the distance (l) between a member and the device 7. Consequently, the lens 14 moves and when focusing is obtained, the motor M is stopped. Consequently, the lens 14 becomes irrelevant to driving relation in focusing and any lens is applicable.

Abstract: PROBLEM TO BE SOLVED: To improve reliability for a noncontact type IC card or the like mounting a logic integrated circuit device by realizing a circuit device having a chip crack detecting function. SOLUTION: In a noncontact type IC card or the like provided with an antenna wiring AW, a resistance wiring RW for detecting chip cracks is formed along four sides of a semiconductor substrate CHIP of a logic integrated circuit device LSI, and a set input terminal and a reset input terminal are formed. A flip-flop in which an output signal turns into an internal reset signal IRST, a first delay circuit which contains the resistance wiring RW as a resistor R1, delays an external reset signal RST by a specific delay time, and transfers the signal to a cassette input terminal of the flip-flop, and a chip crack detecting circuit BD which receives practical resistance change of the resistor wiring RW and discriminates the generation of chip cracks in the semiconductor substrate CHIP are installed.  The detection circuit BD contains a second delay circuit, which delays the external reset signal RST by a specific delay time and transfers the signal to the reset terminal of the flip-flop. The delay time is longer than the delay time of the first delay circuit in the normal state but is shorter than the delay time, when chip cracks are generated.
