Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To provide an easy assembling work and size reduction by forming a magnet integrally with a needle assy., and rotating the assy. by a magnet receiving a magnetic field generated from a magnetic coil. SOLUTION: A needle assy. 20 is mounted on an instrument plate 11. A plurality of magnetic coils 30 are arranged to annularly surround the assy. 20. Current responsive to a rotational speed of a system to be measured flows in each coil 30, which generates magnetism of a magnetic flux density different in response to the measured speed. The assy. 20 has a base 22, a needle 23 and a needle shaft 21. The shaft 21 is engaged with a support 13 provided at a central position of the coils 30 to rotatably hold the base 22 at the plate 11. A magnet 24 contained in the base 22 rotates the assy. 20 upon receipt of a magnetic force from the coils 30. Thus, the assy. 20 is formed integrally with the magnet 24 to eliminate a magnet rotor, thereby providing a constitution of an easy assembling work and size reduction.

Title: Facsimile equipment
Inventor: SAITO HAJIME
IPC: H04N1/40
Filed: 1989-09-29
Abstract: PURPOSE:To decrease dispersion in density and to improve the picture quality by providing a control means applying a drive pulse to plural heaters again when a recording medium is recorded in the random recording mode and a succeeding line picture data is not received before the end of application of the drive pulse to plural heaters. CONSTITUTION:Strobe signals S1-Sn are sequentially applied to a thermal head 8 in the random recording mode, and when a picture data of a succeeding line is not received before the end of application of the strobe signals, a drive pulse with a prescribed pulse width is applied again to the thermal head 8. Since the wait time from the end of application of the drive pulse to the thermal head 8 in the recording of a line till the wait time up to the start of application of the drive pulse of a succeeding line is reduced, the temperature decrease in the thermal head in the wait time is reduced and the dispersion of each line of the print density is reduced. Moreover, the dispersion in the print density is suppressed by increasing the application number of time of the drive pulse.

Title: Driver for wire dot printing head
Inventor: TANUMA JIRO
IPC: B41J2/30
Filed: 1989-09-29
Abstract: PURPOSE:To improve printing quality and to reduce power consumption by detecting a magnetic flux by using a detecting coil and a magnetic flux detector, and determining the end timing of excitation of an electromagnet based on the detection result. CONSTITUTION:A coil 23 of an electromagnet 24 selected by a wire election signal WS is excited by a current flowing through a passage P1. Accordingly, a magnetic flux in a core is varied with the current, and as the current increases, the magnetic flux in the core 21 is cancelled to be decreased. When the magnetic flux in the core is sufficiently reduced until an armature is released and a printing wire 12 starts moving forward, it is detected by a magnetic flux detector 3, a corresponding timing signal TA becomes 'L', and the excitation of the electromagnet 24 is stopped. As a result, a current supply from a power source Vcc is eliminated, but a current continuously flows through a path P2 due to electromotive force in the coil. This current is gradually lowered due to a resistance in the coil 23. When a timing signal TB from a timing extracting circuit 4 becomes 'L', a transistor 84 is turned OFF, thereby interrupting the path P2.

Title: Trouble detecting method for hydraulic control device
Inventor: SAKANE SHINSUKE
IPC: B60T17/22
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a trouble detecting method by which the accumulator pressure can be detected by a cheap means, and a trouble can be detected. SOLUTION: When the brake is depressed until the pressure state of an accumulator becomes a low-pressure state, a motor(MT) is driven to operate a pump. At this time, motor current is detected to estimate the accumulator pressure. Based on the estimated accumulator pressure and the detected value by a pressure sensing means (PS), a trouble in the pressure sensing means is detected. In this case, when the detected value by the pressure detecting means (PS) is high, it is judged to be in high pressure trouble.

Title: Rotary drum device
Inventor: MORI HIROAKI
IPC: G11B5/52
Filed: 1996-09-26
Abstract: PROBLEM TO BE SOLVED: To make an axis of a shaft coincide with that of a hole for fitting the shaft into and to lessen the impact of a shock when the shaft is press-fitted into the hole, by setting specific dimensional tolerances for an inner diameter on one side of a ring-formed groove in an axial direction and for another inner diameter on the other side of the groove in the axial direction respectively. SOLUTION: Being partitioned by a ring form groove, one inner diameter on the side of a fixed drum 2 in an axial direction is set to have a dimensional tolerance of an interference fit to a shaft, and the other inner diameter on the other side in the axial direction is set to have a dimensional tolerance of an interference fit to the shaft smaller than the former tolerance on one end rather than a clearance fit. And, the shaft is press-fitted to the fixed drum 2 from the other end. Since the shaft is fitted into the above-mentioned other inner diameter first, the impact is low, therefore, a permanent deformation due to non-coincidence in the diameters is little to cause a problem.

Title: Semiconductor storage circuit
Inventor: MIYAUCHI MASAYOSHI
IPC: G11C11/409
Filed: 1990-09-25
Abstract: PURPOSE:To increase an input/output speed of data even if a level of the data inclines to either of the power source potential side or earth potential side by making the constitution so that 1st and 2nd input/output lines for data are both precharged with a half of the power source potential. CONSTITUTION:When the high level and low level data of bit lines BL11, BL12 amplified by a sense amplifier SA1 are transmitted to the input/output lines IOL1, IOL2 for data through a row switch circuit 2, the input/output line IOL1 for data is charged from Vcc/2 level to the high level of (Vcc-Vgamma) level (Vgamma is the threshold voltage of a transistor Q11), and the input/output line IOL2 is discharged to the low level. The data transmitted to the input/output lines IOL1, IOL2 are supplied to an input/output circuit 4 and outputted to the outside as output data DT0. At this time, even in the case the level of transmitted data inclines to either of the power source potential Vcc side or earth potential side, the speed difference for charge/discharge becomes small since the charge/ discharge are made from an intermediate potential Vcc/2 between the power source potential Vcc and earth potential.

Title: Coupler connection confirming device for power equipment
Inventor: KAMIYOSHI TOYOHIKO
IPC: G01R31/02
Filed: 1995-09-06
Abstract: PROBLEM TO BE SOLVED: To surely perform the confirmation of connection of a coupler by incorporating the primary and secondary power cables of a coupler and power equipment in connection confirmation positions, and performing the connection confirmation of the coupler directly. SOLUTION: After connection of a coupler 4, the first and second switches 10 and 11 connected to external cables 8 are closed at the same time. At this time, if the pens 4x and 4y of the coupler 4 are connected both, an electromagnetic relay 13 is excited. Moreover, any one of the pins 4x and 4y of the coupler 4 is not connected, the electromagnetic relay is not excited, so it is judged that the coupler 4 is not connected yet. Next, in the same way as above, the coupler 4 is connected, and the switches 10 and 12 are closed at the same time. At this time, if both the pins 4x and 4z of the coupler 4 are connected, the electromagnetic relay 13 is excited. Moreover, unless any one of the pins 4x and 4z is connected, the electromagnetic relay 13 is not excited, so it is judged that the coupler 4 is not connected yet.

Title: Spindle oscillation prevention device for machine tool
Inventor: NAKAGAWA HIROSHI
IPC: B23B19/02
Filed: 1986-10-28
Abstract: PURPOSE:To prevent oscillation of a spindle, by connecting a drive shaft of a generator with a resistance load and fixed with respect to a machine tool to a spindle of the machine tool. CONSTITUTION:When a spindle 1 of a machine tool is rotated by a driving motor 4, the spindle 1 drives a generator 8 directly connected to it. The driven generator 8 produces an induced motive power depending on a magnitude of a field current and supplies a current to a resistance load 10. With the arrangement, torque necessary for power generation acts upon the spindle 1 as a viscosity resistance. A magnitude of the viscosity resistance can be easily regulated by changing the field current and/or the resistance load 10 of the generator 8. The addition of such a viscosity resistance prevents oscillation of the spindle 1 caused by the driving motor 4, whereby a cutting performance of the machine tool can be greatly improved.

Title: Grid resistor
Inventor: MASUDA YOSHIHISA
IPC: H01C3/10
Filed: 1992-09-24
Abstract: PURPOSE:To reduce the noise generation when a current is applied, and to prevent the shortening of life of a grid resistor by a method wherein the plate thickness of the resistor pieces on both ends, among resistor pieces, is made thicker than that of the resistor pieces in the middle part. CONSTITUTION:In a grid resistor in which striplike resistor pieces are arranged in a plurality of rows leaving the prescribed intervals, the plate thickness of the resistor pieces 2A and 2B on both ends, among resistor pieces 2A, 2B...2N, is made thicker than that of the resistor pieces in the intermediate part. As a result, the vibration, caused by the electromagnetic force added to outside direction against the resistor pieces on both ends, can be reduced by the improvement in rigidity obtained by the increase in plate thickness of the resistor pieces of both ends, the generation of noise by the vibration when current is applied can be reduced, and the shortening of life of the resistor can be prevented.

IPC: H01F27/08
Filed: 1984-12-04
Abstract: PURPOSE:To reduce an accessory loss and to prevent frequent adjustable speed of changes of load electric current of a transformer by variable speed controlling an induction motor of a cooler for the transformer with a variable voltage and variable frequency inverter. CONSTITUTION:A rate-of-change limiter 10 is provided between a function generator 8 and a variable voltage and variable frequency inverter 9. A load current of a transformer 1 detected by a current transducer 7 is changed into a frequency signal corresponding to a load factor of the transformer by the generator 8, and is added to an adder 10a in the limiter 10. An output of the adder 10a is level-detected by a comparator 10b. Then, a variable speed control by the inverter 9 changes slowly the number of revolutions. Therefore, reduction of an accessory loss will be effected and a frequent adjustable speed by a change of a load electric current of the transformer will be prevented.

Title: Clock phase setting circuit
Inventor: OIKAWA YOSHINORI
IPC: H03K5/13
Filed: 1989-09-29
Abstract: PURPOSE:To output a clock signal with a desired phase difference automatically in a range even when the frequency of an input clock signal is changed by generating a clock signal having a phase difference by a period of 1/2<m> from a phase of the input clock signal automatically. CONSTITUTION:An input clock signal CLKi is counted by a counter CTR and the result of count is fed to delay circuits DL0-DL(n-1). Then the signal CLKi is sequentially retarded by a time tau each and the counter CTR is brought into the holding state when the retarded clock signal is deviated from the input OLKi signal by nearly 1/2 period. Then the output of the counter CTR is shifted at a shifter SIFT by (m-1) bits and the result is fed to the delay circuits DL 0-DL(n-1). Thus, the delay of nearly 1/2 period is grown into a delay of nearly 1/2<m>, and an output clock signal CLKo having a phase difference by a period of 1/2<m> from a phase of the input clock signal CLKi is generated.

IPC: F25D23/02
Filed: 1988-10-11
Abstract: PURPOSE:To prevent the dewing on the surface of the decorative panel by a simple construction and facilitate the assembly process by disposing screw holes for attaching the decorative panel and a height difference for a reinforcement plate around the rim of the door main body, covering the screw heads with a gasket, and fitting a reinforcement plate to the lower part of the door main body. CONSTITUTION:A through-hole 17 is disposed in the main body 14, and the main body 14 and a decorative panel 15 are fixedly joined together with screws 18. The screws 18 are installed from the inside of the cabinet, and the screw heads are covered with a gasket 16. A reinforcement plate 20 for attaching the decorative panel 15 is fitted to the lower part of the main body 14. When a refrigerator having the present heat insulated door is set as a part of a system kitchen, a coordinated visual impression is obtained since the same surface material and color tone are used for the door decorative panel 15, while the reinforcement plate 20 is hidden from the frontal view because of the height difference 15a. The heat insulation performance is ensured by the insulation material 7 filled in the door main body 14. In regard to the attachment of the decorative panel 15 to the door main body 14, there is no need for a complex construction as was seen in the prior art because the reinforcement plate 20 is fitted to the lower part of the main body 14 and the attachment screws 18 are covered under the gasket 16, facilitating the assembly process. Therefore, the heat insulated doors can be manufactured at less cost.
