Patent JP-S63221403-A (JP)
Title: Industrial robot device
Inventor: KATO HISAO
IPC: G05B19/18
Filed: 1987-03-11
Abstract: PURPOSE:To easily control three absolute axes X, Y and Z of the robot software to the reference surface for installation of a robot by providing said reference surface, the measurement surfaces of three directions having the specific relations with the reference surface, and a detecting means which detects the actual shift value between the measurement surface and the tip of the robot arm. CONSTITUTION:A robot arm 4 is set horizontal to the lower surface of a flange 7. A gamma axis is turned with an MDI operation so that the light 14 of a projector 13 set on the lower surface of the flange 7 projects a surface ABC vertically. Thus the robot tip is moved up to a desired position. When the MDI command value is different from the light receiving information value (actual measurement of tip shift) of each surface, a computer 15 corrects a RAM 17 so that the absolute axes X, Y and Z are correctly controlled onto a reference surface 9 for robot installation. In such a constitution, a teaching action is not needed in a confronting state between the robot and an equipment. Thus the working efficiency is improved before the start of the robot operation.

Title: Detector circuit
Inventor: OOO YOSHIHISA
IPC: H04N5/14
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To provide an output of a current whose flowing direction is set in the same direction by changing reversibly the direction of current among a capacitance terminal and plural circuits in the circuit operation of comparison and discrimination for plural kinds of input signals whose current flowing direction is not definite. SOLUTION: This circuit is provided with plural detector circuit sections A, B consisting of plural transistors(TRs) P1 -P8 and Q1 -Q8 and selected alternatively for the operation of signal comparison/discrimination and with a single capacitance terminal TC connected to both the plural detector circuit sections in a way that the current flowing direction is opposite to each other for the connection to the plural detector circuit sections. Since the single capacitance terminal is used in common for the plural detector circuit sections and provide an alternative output of currents whose flowing directions from the plural detector circuit sections are opposite to each other, the one circuit copes with current flowing in both positive and negative directions.  Thus, the one circuit is enough for comparison and discrimination of plural kinds of signals whose current flowing directions are opposite to each other.

Title: Contactless ignition device
Inventor: FUJINO HIROYO
IPC: F02P5/155
Filed: 1984-03-23
Abstract: PURPOSE:To prevent power transistor from rupture and heating, and contrive miniaturization as well as reduction of cost of the same by a method wherein the device is provided with an operating level control circuit which elevates the detecting level of an ignition signal detecting unit and shortens the time of conduction of an ignition coil upon switching spark-advance into lage angle side. CONSTITUTION:When an engine is started, an A.C. signal Vp (ignition timing signal), synchronized with the revolution of the engine, is generated in the terminal A of a pickup coil 40. When the signal Vp becomes negative, the transistor 37 is put ON and primary current flows through an ignition coil 41 while a high voltage is generated in the coil 41 when the signal Vp is changed from negative to positive. An operating level control circuit 55 elevates the bias level of a transistor 30 and shortens the conduction time (t) thereby preventing the increase of the primary current 1c as a battery voltage VB increases. On the other hand, ignition is effected at zero cross point regardless of the battery voltage VB and the revolving number of the engine, therefore, the position of ignition may be stabilized.

IPC: G11B7/00
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To provide a device capable of controlling access to an optical disk so as not to cause overflow and underflow in a buffer memory having simple circuit constitution. SOLUTION: When write-in to a next track is started, whether or not the data of a maximum recording data amount or above of one track on an optical disk exist in a buffer memory 14 is discriminated in a unit of blocks. When the blocks storing the data exist more than required ones, the write-in to the track is performed, and when not, the write-in is interrupted. At a reproducing time, when a free area for more than the data amount read out from one track doesn't exist in the buffer memory 14, the read-out from the optical disk is interrupted. When the blocks more than required ones don't exist, the access is interrupted, so that the underflow and the overflow don't occur while one track is under recording/reproducing. Further, since the blocks are used as a unit, constitution of a discriminant circuit is simplified.

Title: Preventing method of false determination of estimation of power swing of generator
Inventor: ISHIBASHI SATORU
IPC: H02H3/48
Filed: 1990-03-07
Abstract: PURPOSE:To detect separation of a generator at a high speed and also to prevent false determi nation of a system by providing a generator separation detecting unit which determines whether or not the generator is separated from a system line, by using a voltage and a current of the generator, and also a power swing estimation computing unit and a power swing determining unit. CONSTITUTION:An undercurrent relay element 15 receives a generator current as an input and the output thereof is connected to an inhibit input end of an inhibit circuit 16. A power swing estimation computing unit 12 receives the generator current and a generator voltage as inputs and the output thereof is connected to the other end of the circuit 16. The relay element 15 detects that the generator current does not flow, and it does not operate when a generator 14 is connected to a system line, and operates when a prescribed formula is satisfied. When a fault of the system line is detected, in this constitution, the computing unit 12 starts computation. When a power swing is determined as the result of the computa tion, the generator 14 is regarded as separated from the system line and the determination of the power swing becomes ineffective finally, when the relay element 15 is in a state of operation. Since the relay element 15 is ordinarily in a state of nonoperation, the result of computation of the computing unit 12 becomes final determination of the power swing as it is.
