Title: Disk driver
Inventor: KONNO MAKOTO
IPC: G11B21/02
Filed: 1995-03-10
Abstract: PURPOSE: To provide a disk driver having a function correcting a thermal off- track. CONSTITUTION: A correction piece 29 whose thermal expansion coefficient is different from that of a disk is combined with a carriage arm 25 being a part of a head carriage 20 having a lower carriage 21 loading a magnetic head 23 and an upper carriage 22 loading another magnetic head, and the carriage arm is deformed, making an engagement part between a pin 26 and a drive shaft 30 a fulcrum, by the deformation action of the correction piece according to an ambient temp. change. Thus, the positional deviation of the magnetic head 23 loaded on the head carriage is corrected. Further, by constituting the upper carriage of a length shorter than the lower carriage with material having the rate of thermal expansion larger than the lower carriage, the positional deviation of the magnetic head caused by a difference between both lengths is corrected.

Title: Reverse charge preventing device
IPC: H02H3/34
Filed: 1992-03-09
Abstract: PURPOSE:To provide a reverse charge preventing device which can effectively stop a distributed power source system in response to opening, etc., of a breaker or a switch of a high voltage distribution line even when an output of the system is balanced with power consumption of a load. CONSTITUTION:Switches 6 such as semiconductor switches, etc., are provided at low voltage distribution lines 3 of a system in which distributed power source systems 5 are interconnected to the lines 3. When a signal due to opening of a breaker, etc., of a high voltage distribution line 1 is received via a communication cable 8, the switch 6 is operated for a short time to ground-fault or short- circuit the line 3. Thus, an effective voltage change occurs at the line 3, and the system 5 is effectively stopped.

Title: Flexible magnetic disk device
IPC: G11B19/02
Filed: 1992-03-09
Abstract: PURPOSE:To improve magnetic efficiency by joining two back cores to a first magnetic core in different planes. CONSTITUTION:The magnetic head mounted on the magnetic disk device has two magnetic gaps for recording/reproducing 4A and for erasing 3A. Magnetic circuits are closed by adding back cores 6a, 6b which can be separated from the head. Thus, the magnetic core between the gaps 4A, 3A is made in one body without having a magnetic separation layer. The magnetic gap 4A for both of recording and reproducing is formed to have the length between >=0.45mum and <=0.55mum and depth between >=5mum and <=40mum from the sliding surface of both cores to a medium. The back cores 6a, 6b are joined to the first magnetic core 1A on different planes.

Abstract: PURPOSE:To decrease the disconnection defects of source wirings by forming 1st source electrode wirings of the same material and forming 2nd source electrode wirings thereon, thereby forming the source electrode wirings into two- layered structures at the time of forming picture element electrodes. CONSTITUTION:The source wirings are formed into two-layered structures 3, 10 and the patternings thereof are respectively separately formed with a display device formed by using thin film transistor arrays and, therefore, even if a patterning defect or the like is generated in either of the wiring layers by cracks, defective coverage and dust, etc., the wires are connected by another layer and the disconnection defect is consequently, prevented. The probability that the pattern defect or the like arises in the same place is extremely low. The disconnection defects of the source wirings are thereby decreased with the same number of stages as heretofore.

Filed: 1990-03-02
Abstract: PURPOSE:To surely execute belt deflection preventing control independently of a belt carrying speed by detecting a deflected position detecting pattern to execute deflection preventing control so that a deviation signal to be a movement control variable is synchronized with a position signal based upon pattern detection and formed based upon a reference pulse fixing its duty ratio. CONSTITUTION:Many deflected position detecting patterns 4 having the same shape whose width rectangular to the axis direction of a driving roller is gradually increased and continuously formed along the belt carrying direction are detected to execute deflection preventing control. Namely, the output of a photosensor 3 is shaped by a waveform shaping circuit 10 and detected by a detector 11 and the detected signal is converted into a deviation signal, which is outputted to a belt moving means 12. The reference pulse to be used by the detector 11 is synchronized with a position signal based upon the detection of marks 4, its duty ratio is fixed and a reference pulse for a phase comparator 14 is formed by a PLL circuit 13 based upon the position signal. Thus, the reference position of the axial direction can be fixed independently of the carrying speed of the belt and deflection preventing control can surely be executed.

IPC: H04M7/06
Filed: 1998-02-18
Abstract: PROBLEM TO BE SOLVED: To transmit a response message while arbitrarily selecting a signal link when testing plural No.7 signal links. SOLUTION: A No.7 signal transmission/reception part 1-2-1 of a No.7 protocol tester 1-2 sends No.7 messages simultaneously received from plural links to a No.7 signal processing part 1-2-2, which analyzes the received No.7 messages and sends the analyzed results to a scenario control part 1-2-3. The scenario control part identifies a reception link name from the message analyzed results of the respective links, determines a variable name to store the reception link number according to the scenario stored in a scenario storage part 1-2-5, sets the reception link number to the determined variable and stores it in a variable storage part 1-2-4.  When transmitting a message corresponding to the received No.7 message, link numbers are extracted out of variable names stored in the variable storage part and according to the scenario stored in the scenario storage part, the link number to be transmitted is determined. Corresponding to an instruction of the scenario control part, the No.7 signal processing part prepares a No.7 message containing the link number to be transmitted and transmits it through the No.7 signal transmission/reception part.

Title: Connector of feed bar
Inventor: IMANISHI SHIYOUZOU
IPC: B21D43/05
Filed: 1979-04-27
Abstract: PURPOSE:To disconnect feed bar from taper block and automatically disconnect the feed bar by feeding pressure fluid and letting cylinder move upward. CONSTITUTION:When pressure fluid is supplied to a pressure fluid feed hole 9c, the cylinder 9 moves upward and the ascending of the cylinder 9 is defined by a hook part 13a.

The feed bar 1 is put in the unrestrained and freely held state. Following to this, the feed bar 1 on the corbel side is moved upward by, e.g., the uperward operation of a moving bolster, and is carried out in the horizontal direction together with the dies by the travelling operation of the moving bolster in the state that it is disconnected from a feed bar rest 12, taper block 11, remaining side feed bar, etc.
