Filed: 1993-03-29
Abstract: PURPOSE:To enable the setting of information to a processor performing a unitary management of information and a computer site/terminal which is in an off line and to manage the set information by keeping conforwability. CONSTITUTION:A MPU 12 writes setting information including ID information 20a and exclusive control information 20b stored in a storage device 20 in an FD 30 in response to the instruction of an operator.

Title: Knocking signal processing circuit
Inventor: AKABOSHI TSUKASA
IPC: G01H17/00
Filed: 1982-04-27
Abstract: PURPOSE:To make possible the detection of knocking with high accuracy by a method wherein reference voltage and knocking voltage being detected are obtained from a sampling signal and both the voltages are compared, so that a knocking detection signal can be outputted. CONSTITUTION:The output of an oscillation detector 32 becomes a signal 54 via a band filter 34 and is divided into two pahts; one of them is applied to an input terminal of a voltage comparator 37 through a switching circuit 35 and the like. This signal is treated as knocking voltage Vn being detected. The other is applied to a switching circuit 40 and then the other input terminal of the voltage comparator 37 as reference voltage Vs. Of the two signals Vn, Vs applied to the voltage comparator 37, while the voltage Vn' being detected exceeds the reference voltage Vs', the voltage comparator 37 outputs a pulse train as a knocking detection signal through a second integrating circuit 38. Since variation in sensitivity can thus be corrected, knocking is detectable with high accuracy.

Title: Method for generating reference frequency
Inventor: OOSHIMA TAKESHI
IPC: H03L1/04
Filed: 1983-04-19
Abstract: PURPOSE:To obtain highly accurate and highly stable frequency simultaneously with turning on a power supply by using the output of a temperature compensating crystal oscillator until the stabilization of oscillation frequency of a highly stable crystal oscillator, and after stabilization, switching said output. CONSTITUTION:When the output of a thermostatic oven controller OVEN CONTROL reaches a prescribed value, an alteration switch SW2 inserted between an oscillation circuit of the highly stable crystal oscillator OCXO and a driving power supply for said circuit is closed to oscillate the OCXO and an alteration switch SW3 inserted between an oscillation circuit of the temperature compensating crystal oscillator TCXO and its driving power supply is opened by using the output signal of the OCXO. Thus, only the TCXO is driven until the stabilization of the oscillation frequency of the OCXO, and after stabilizing the frequency of the OCXO, the TCXO stops driving and only the output of the OCXO can be used.

Title: Ink-jet recording head and its manufacture
Inventor: KOTAKE NAOSHI
IPC: B41J2/16
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To provide an ink-jet recording head and its manufacture whereby the ink-jet recording head can be assembled simply and accurately without being influenced by accuracy at the time of molding. SOLUTION: A groove part 3 defining an ink passage is formed of a thick resin film layer 2 layered at the side of a substrate 1. A part of a nozzle plate 4 corresponding to the ink passage is made a flat part 6. Since a minute structure is eliminated to mold and process the nozzle plate 4, no consideration into a positional shift consequent to thermal shrinkage is necessary and the nozzle plate can be molded and processed easily. Since no minute groove interfering with laser light is present, nozzle holes 5 of a predetermined shape can be opened with a correct pitch in the nozzle plate 4. In addition, the ink passage and a heat-generating body accompany no shift when the substrate 1 is bonded to the nozzle pate 4. The substrate and the nozzle plate can be bonded simply after the ink passage and the nozzle hole 5 are registered, and therefore assembled easily.  The ink-jet recording head having individual ink passage of nearly uniform ink discharge characteristic is obtained in this manner.

Title: Controlling device for electronic circuit
Inventor: MATSUZAKI KENICHI
IPC: H05K13/00
Filed: 1992-02-20
Abstract: PURPOSE:To make it possible to reuse easily a driver section, a drive section or the like. CONSTITUTION:A drive section-attached driver 6, which integrates a drive section and a driver and the like with a bracket or the like, is mounted on an electronic circuit board presser board 5. When the driver and the drive section and the like are reused, the driver 6 attached to the drive section is removed as it is in once piece, and mounted on a different presser board 5. Two universal joints are installed to a drive shaft of the driver attached to the drive section so as to deviate the position of the drive section, which makes it possible to control a control element laid out at an interval smaller than the diameter of the drive section.

Title: Disc holder
Inventor: YOSHII TETSUJI
IPC: G11B17/028
Filed: 1985-04-03
Abstract: PURPOSE:To increase the intrinsic frequency of a disc in the holding state and to quicken the attenuation of vibration by depressing a turntable and a disc supported by the turntable with a pressing member formed in a diameter larger than a turntable outer diameter. CONSTITUTION:The outer diameter D2 of a disc pressing member 3 is formed larger than the turntable diameter D1 and inner diameter D3 is formed smaller than the D1. Thus, even when the clamping area standardized giving no hindrance to the running of a pickup is supported at the turntable side, since an area wider than the clamping area is depressed at the upper side of disc, the intrinsic frequency is increased, the attenuation of vibration is quickened and a disc tolerant to vibration is attained.

Title: Manufacture of stator for molded motor
Inventor: DOI YUUJI
IPC: H02K15/12
Filed: 1984-04-09
Abstract: PURPOSE:To prevent resin from entering a bearing inserting hole by sealing by holding the projection of a flange of a bracket in a molding die with a recess when simultaneously molding a winding and the bracket by resin molding. CONSTITUTION:A stator core 6, a winding 8 and a bracket 5 are integrally molded with molding resin 4, thereby molding a stator for a motor. This molding is performed by inserting the bracket 5 into a mandrel 3, clamping the mold together with an upper molding, and molding the resin. In this case, an annular projection 5d is formed on the flange of the bracket 5, and a recess 5e is formed on the opposed surface. The projection 5d and the recess 5e are closely contacted by mold clamping by holding with the upper neck 1a and the end face 3a of the mandrel 3. Thus, the resin 4 introduced to the outer peripheral line of the projection 5d at the molding time is stopped to be introduced into the inner peripheral side with the projection 5d and the recess 5e, thereby preventing a resin burr from forming on the inner surface 5b in the bearing inserting hole.

An oscillating lever 44 is revolved in the revolving direction of the capstan 35 (i.e. clockwise) by means of the rotary frictional power produced among gears 42 and 43 and the lever 44. The gear 42 is engaged with a gear 39 unified with a forward take-up reel drive disk 38, and at the same time the gear 43 is separated from a gear 41 unified with a reverse take-up reel drive disk 40. In a reverse record/reproduction mode, the motor 32 is revolved counterclockwise and therefore the capstan 35 is also turned counterclockwise. Then the lever 44 is reversed in the revolving direction (i.e. counterclockwise) of the capstan 35.
