Title: Theft proof device
Inventor: HARUMOTO SATORU
IPC: B60R25/04
Filed: 1995-03-17
Abstract: PURPOSE: To dispense with an input terminal exclusive to a theft proof device in a microcomputer to control an engine by stopping to operate the engine by a control means when a signal not likely to be outputted by a signal output means is inputted to the input terminal of the control means from a theft signal generating means. CONSTITUTION: When a Hi-Lo signal of 50Hz is inputted to an input terminal TE, a microcomputer 1 judges that a vehicle is put in a condition likely to be stolen, and prohibits current-carrying to an ignition device 4 and an injector 5, and stops to operate an engine. A theft sensor 2 can make the microcomputer 1 stop to operate the engine by outputting the Hi-Lo signal of 50Hz to the input terminal TE of the microcomputer 1. Therefore, since the input terminal TE to input an output signal of a test switch 3 to be used in engine control can also be used as an input terminal to input an output signal of the theft sensor 2, there is no need to arrange an input terminal exclusive to the theft sensor 2 in the microcomputer 1.

Filed: 1992-02-13
Abstract: PURPOSE:To effectively arrange many robots with high density by automatically calculating the real working area of each robot based on the attitude data on the robot obtained from the simulation carried out according to an operating program. CONSTITUTION:The moving attitude of a robot is simulated in each fixed cycle based on the robot shape and an operating program stored in a disk 2. Then the apex position of the robot contour shape approximate to a polyhedron is detected as the data on the three orthogonal axes in each cycle. A ball area is calculated with the coordinate positions consisting of the maximum and minimum axis data forming the apex position defined as the both ends of the ball area. At the same time, a rectangular parallelepiped area is also calculated with a segment connecting those coordinate positions together defined as a diagonal line of the rectangular parallelepiped. These calculated areas are stored in the disk 2 as a robot space. Meanwhile the minute spaces including apexes are integratingly stored in a RAM 4 in each cycle. Then an area formed with all stored minute spaces is stored in the disk 2 as a robot working space.

Title: Optical transmitter
Inventor: AZUMA TOORU
IPC: H04B10/572
Filed: 1981-04-17
Abstract: PURPOSE:To make an optical output constant without reference to fluctuations of temperature, a secular change, and variation in background light, by providing a background light breaker to an optical transmitter used for optical space communication, and thus cutting the background light. CONSTITUTION:A light emitting element 10 placed at the focal point of a lens 11 is driven by a light-emitting-element driving circuit 9 to generate an optical output according to an input signal. The optical output is collimated through the lens 11 and transmitted to a reception sie, but part of the optical output is converted into an electric signal by a photodetecting element 13 placed where the main beam of the light emitting element is not disturbed and then amplified by an amplifier 14 before being applied to the driving circuit 9. Since the influence of background light is removed from the photodetecting element 13 by a background light breaker 12, the output of this optical transmitter is made constant without reference to fluctuations of temperature, a secular change, and variation in background light.

IPC: F28F11/00
Filed: 1980-05-02
Abstract: PURPOSE: To detect quickly and accurately a minute leakage of a heat transfer medium for the closed type heat exchanger by a method wherein a detection is designed so as to determine whether or not a marking substance mixed in one heat transfer medium is present in the other heat transfer medium.

When the primary heat transfer medium leaks, the leaking medium drops into a vessel 6 as drain water 5 while the marking substance is mixed in a secondary heat transfer medium 4. The drain water in the vessel 6 is then introduced into a leakage detector 7 where ultraviolet rays are applied on the drain water to see if visible fluorescence is exhibited from the drain water, whereby the presence or absence of the marking substance is detected to ascertain the leakage of the heating medium 1.

Filed: 1997-03-13
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous detection and erroneous calculation by stopping transmission and outputting only the offset voltage of a receiver and a noise signal and obtaining an offset from the average value of the reception signal and performing offset compensation. SOLUTION: A transmission switch 3 is turned off, and an A/D converted 9 converts a reception signal to a digital signal in a state of only signal reception having been made. The reception signal includes an offset voltage when an offset adjustment deviates and can be obtained by calculating an average value. An average value calculation means 11 samples a plurality of reception signals for an offset voltage calculation period and obtains an average value and sends it to an offset-compensating means 10. The transmission switch 3 is turned for a normal measurement state. The offset compensation means 10 subtracts an offset voltage that is set by the average value calculation means 11 from a digitized reception signal received from an A/D converter 9. The signal is inputted to a frequency analysis means 12 to obtain the frequency of a target.  Further, the relative speed and distance of a target are obtained by a distance/speed calculation means 13.
