Title: Temperature detection of rotor in centrifugal separator
Inventor: TAKAMURA TSUTOMU
IPC: B04B15/02
Filed: 1991-07-31
Abstract: PURPOSE:To detect the temperature of a rotor with good precision by sticking many pieces to be detected on the surface of a rotor and counting the number of the piece to be detected which reacts with temperature and, as a result, has been enlarged in reflectivity. CONSTITUTION:Many pieces 2 to be detected are radially arranged on the surface of a rotor 1 around a rotary shaft at every temperature of resolving power to the upper limit value from the lower limit value in a range of temperature detection. Pieces are stuck by coating wherein an adhesive or liquid material is used. A light emission diode 3 is fixed on the bottom face of a chamber 5. The bottom of the rotated rotor 1 is irradiated therewith. When irradiated light 7 collides against the pieces 2 to be detected, reflected light 8 is made incident on a photodiode 4 provided on the bottom face of the chamber 5 and converted into a pulse by a temperature signal detection circuit 10. This pulse is sent to a counter 13. On the other hand, a pulse generated at every one revolution of the rotor 1 is sent from a rotation detection device 11 and a rotation signal detection circuit 12. The counter 13 counts the number of the piece 2 to be detected wherein reflectivity has been enlarged while the rotor 1 makes one revolution. A CPU 14 converts and detects the temperature of the rotor 1 from the number this piece 2 to be detected.

Title: Table driving device
Inventor: TOMOTAKI KATSURA
IPC: B24B47/04
Filed: 1993-07-30
Abstract: PURPOSE:To move a table precisely without receiving the influence of the deflection component of a nut with the rotation of a feed screw by providing a connection part for connecting a fitting part of a nut holder to a part of the table, which is to be fitted to a guide part, through a ball rolling within the surface crossing the moving direction of the table. CONSTITUTION:A ball screw 14 is rotated by a driving motor 15, and a nut 16 is moved along the ball screw 14, and with this movement, a nut holder 17 is moved along a guide part 11a of a base 11. A table 10, which is connected to a fitting part 17b of this nut holder 17 through a connecting mechanism 20 as a connection part, is guided for movement by the base 11 and the hydrostatic guide surface of the guide 12. At this stage, with the rotation of the ball screw 14, the deflection component is generated in the nut 16 and the nut holder 17, but since the ball inside of the connecting mechanism 20 is rolled within the surface crossing the moving direction of the table 10, this deflection component is not transmitted to the table 10.

The exhaust hole 11 is fitted with a guide means which leads the return oil in the direction along the surface of the working oil captured by the reservoir 3 and precludes wave formation originating from falling of the return oil onto the oil surface.
Patent JP-H0851733-A (JP)
Title: Constant current control circuit
Inventor: OHASHI TOSHIHARU
IPC: H02M3/28
Filed: 1995-07-26
Abstract: PURPOSE:To obtain good constant current characteristics by inserting a constant voltage element between an amplifier for amplifying the voltage across a current detecting resistor and a control circuit for sustaining the supply current at a predetermined level. CONSTITUTION:A voltage corresponding to the supply current to a load (secondary battery) 7 appears across a current detection resistor R12 and amplified through an amplifier OP1. A control circuit 14 then sustains the supply current at a predetermined level depending on the output level from the amplifier OP1. Since a constant voltage element 13 is inserted between the amplifier OP1 and the control circuit 14, output voltage from the amplifier OP1 is fed to the control circuit 14 only when the output voltage level of the amplifier OP1 exceeds a level predetermined by the constant voltage element 13. Consequently, the amplification factor of the amplifier OP1 can be increased and the supply current is held at the predetermined level accurately regardless of the state of the load 7. This constitution realizes good constant current characteristics.

IPC: H02P1/28
Filed: 1981-11-30
Abstract: PURPOSE:To suppress the rush current at the time of changing a tap by automatically switching all taps of an autotransformer and starting a motor. CONSTITUTION:When a start pushbutton switch is closed, electromagnetic contactors 6-N, 6-1 are closed, and a voltage of 25% of full voltage is applied to a motor 1.

After several seconds, the contactor 6-N is closed, and the voltage of 42% of the full voltage is applied to the motor 1. Thereafter, the contactors 6-3, 6-4 are similarly sequentially closed, the voltage applied to the motor 1 is sequentially increased. In this manner, the rush current at the time of changing the taps can be suppressed.

A segment is assembled while being supported by the support 28. When the segment inclined and fixed in the longitudinal direction 33 interferes in an existing segment and the segment cannot be inserted, the adjusting device 34 is expanded and contracted, and the inclination is corrected. Accordingly, the inclination of the segment can be adjusted easily.

Title: Control circuit for damping force variable type hydraulic shock absorber
Inventor: KAKIZAKI SHINOBU
IPC: B60G17/015
Filed: 1982-10-30
Abstract: PURPOSE:To prevent the occurrence of a fire attendant upon the generation of heat in a motor and a harness as well as of any damages and the like attributable to overload in a driving circuit itself, by installing a current limit circuit in space between a driving motor of an adjuster for car's damping force adjustment and the driving circuit. CONSTITUTION:When a driving shaft 4a of a driving motor 4 for a damping force adjuster 8 between a car body and an axle happens to be locked during rotation for driving whereby an overcurrent is produced at the motor 4 side, a potential difference beyond the specified value is produced between the motor 4 side of a potential difference generating resistance 30 and a transistor 29 side, so that a transistor 32 comes into a state of being turned on, and thereby part of a base current of the transistor 29 flows into a collector terminal of the transistor 32. Therefore, the base current of the transistor 29 decreases as much as for a portion of the outflow and since a collector current is also decreased, a flow rate in an excessive driving current flowing into the motor 4 from a power source 28 can be limited by action of the transistor 32. Accordingly, and damages to these driving systems following the generation of heat in the motor 4 and the harness can be prevented from occurring.

Abstract: PURPOSE:To prevent malfunction due to the separation of a card module from a loading part accidentally from being generated, by detecting the separation of the card module from the loading part in the access state of a memory device by a detecting means, and regulating the control operation of an electronic equipment based on a detected result. CONSTITUTION:By drawing out a memory card 1 from the connector 2 of a printer main body, a loading/unloading state detecting signal of H level is outputted from a loading/unloading state detection mechanism 3 to an AND gate 5 before generating the non-contact state of the contact 1a of the memory card 1 to the contact 2a of the connector 2 on the process of drawing out. And furthermore, since a chip select signal CE of H level from a CPU4 is inputted to the AND gate 4, a signal of H level is outputted from the output terminal of the AND gate 5 to the interruption terminal of the CPU4. And the CPU4 starts an interruption processing keeping the connection state with an external memory, and the control operation performing until then is stopped. In such a way, it is possible to prevent the malfunction due to the unstability of readout data from being generated.
