Title: Stepping motor drive
Inventor: KOBAYASHI KOICHI
IPC: H02P8/06
Filed: 1999-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent the timing of initial position detection from being different between the forward and reverse rotations of a stepping motor. SOLUTION: This stepping motor drive is provided with a stepping motor 3, capable of forward and reverse rotation serving as its driving source and consists of a driving member 2 connected to the stepping motor 3 to operate, a detecting part 8 for conducting signal detection according to the operating position of the driving member 2, and a control part 7. The control part 7 sets the initial position of the driving member 2 at a position where the driving member 2 is rotated forwardly by the number of prescribed steps from an ultimate position to which mechanical regulation is applied, so that the driving member 2 starts its operation therefrom. The stepping motor 3 is rotated once in reverse to conduct the signal direction at the signal detecting area of the detecting part 8 and verify that the driving member 2 operates as prescribed.  The stepping motor 3 is rotated forwardly to move the driving member 2 to a target position. When the driving member returns from the target position to the initial position, the stepping motor 3 is rotated in reverse to return the driving member 2 to the signal detecting area for signal detection and verify that the driving member 2 operates as prescribed, and the stepping motor 3 is rotated normally to set the driving member 2 to the initial position.

IPC: H01P1/15
Filed: 1996-10-29
Abstract: PROBLEM TO BE SOLVED: To provide a compact diode switch by forming a 1st and 2nd transmission lines in the layered products and connecting a capacitor in parallel to the 1st transmission line to extremely shorten the length of this line. SOLUTION: An Ag electrode is formed by screen printing on a layered product sheet produced by a doctor blade, so that a pattern is formed, laminated and bonded on the sheet to be baked in a single body. The terminal electrodes 603, 604, 605 and 606 are formed on the side faces of the layered product. The terminal of a semiconductor device 602 containing two diodes is connected to the pattern electrode, and a chip capacitor 607 is connected to another pattern electrode. That is, the length of a 1st transmission line can be extremely shortened when a capacitor is connected in parallel to the 1st transmission line. As a result, a compact diode switch is obtained and accordingly a portable telephone set containing a switch circuit or a high frequency circuit can be miniaturized.

Title: Wiper control device
Inventor: NOMURA TETSUYA
IPC: B60S1/08
Filed: 1990-10-26
Abstract: PURPOSE:To perform wiper control matching the feeling of a driver even during the stop of a vehicle by detecting the number of revolutions of an engine and performing fixed intermittent operation according to an amount of rainfall. CONSTITUTION:During running of a vehicle, a microcomputer MC detects it based on the number of revolutions of an engine whether or not an engine is in an idling state. When it is not in an idling state (a vehicle runs), auto wiper control is effected. Meanwhile, when it is detected that an engine is in an idling state (a vehicle is stopped), it is discriminated whether the operation mode of the wiper before a stop is a high speed or a low speed continuous operation mode. When it is an intermittent mode, since it is equivalent to a time when an amount of rainfall is comparatively low, operation of a wiper is effected such that the wiper is inoperative for five seconds and operated for five seconds at a time. Meanwhile, in the case of a high speed or low speed continuous operation mode, the wiper is inoperative for two seconds and operated for two seconds at a time.

Filed: 1997-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent an operator from inputting another operation instruction to a device erroneously by canceling the instruction with a control part even when it is inputted whilst a reproduction is executed according to an operation instruction. SOLUTION: When an operation instruction is inputted to an input part 1, after a control part 2 stores it in a storage part 3, the part 2 reads out the operation instruction to instruct it to a reproduction part 4 and makes the reproduction part 4 execute the operation instruction and also the part 2 raises a flag indicating that the part 4 is executing the instruction in a memory being in the control part 2. When a new operation instruction is inputted to the input part, the part 2 allows an output part 5 to generate an output concerning an alarm in characters when the part is a display and in a voice when the part is a speaker and also the part 2 cancels the new operation instruction.  When the part 2 judges that the part 4 completed the operation instruction, the part 2 pulls down the flag indicating that the part 4 is executing the instruction and also it stops the output concerning the alarm of the output part 5 to make the device a standby state.

Title: Production of magnetic recording medium
Inventor: CHIBA KAZUNOBU
IPC: G11B5/84
Filed: 1989-11-07
Abstract: PURPOSE:To allow the application of a fluorocarbon lubricant without using a fluorocarbon solvent by applying the emulsion of the fluorocarbon lubricant on the surface of a magnetic layer. CONSTITUTION:The major point with this medium is to apply the emulsion contg. the fluorocarbon lubricant as its internal phase on the surface of the magnetic layer. Namely, there is no need for dissolving the fluorocarbon lubricant in a molecular state and, therefore, there is no need for using the fluorocarbon solvent which is heterofore considered to be the only good solvent of the lubricant and such is extremely preferable in terms of environmental maintenance. The liquid to be used for constituting the outer phase of the emulsion is general-purpose org. solvents and water which are all easily available and do not exert any influence at all on economy. The liquid of the outer phase is evaporated away after the application of the emulsion and, therefore, the coated film formed is thin and uniform and the lubricity thereof is good.

Filed: 1993-11-17
Abstract: PURPOSE:To widen the selection width of a transistor and to reduce leakage current by constituting the device so that a control signal may be simultaneously inputted to each of plural transistors. CONSTITUTION:When the control signal is inputted to an input terminal B, the control signal is simultaneously inputted to two transistors TR1 and TR2 through wiring parts Lb1 and Lb2. Therefore, in this state, acurrent supplied to the wiring part La from a power source circuit is grounded by continuing the transistors TR1 and TR2, so that output from an output terminal 0 is in an off-state. Next, when the input of the control signal to the input terminal B is turned off, the current of the wiring part La is hardly made to flow on the side of the transistors TR1 and TR2, so that output from the output terminal O is in an on state and power is supplied to a transferring device or the like. Therefore, the on and off control of the output from the output terminal 0 is adequately performed by switching the control signal on and off.
