Title: Driver for pulse motor
Inventor: NARUSE MAKOTO
IPC: H02P8/32
Filed: 1978-09-14
Abstract: PURPOSE:To improve the transient response of a pulse motor, by feedbacking a voltage induced in an excitation winding to an exciting current to purely electrically add a braking force. CONSTITUTION:An exciting current is sequentially switched to the excitation windings A, A', B, B' of a four-phase pulse motor through switching elements SWA, SWA', SWB, SWB'. Exciting currents IA, IB are controlled constant by constant voltage circuits QA, QB which include series resistors R1, R2. Voltages ea, eb are induced as shown by b3, b3' in Fig. When a rotor tooth approaches a magnetic pole B rightward in stopping the pulse motor by the excitation of poles A, B, the induced voltage ea increases negatively and the other induced voltage eb decreases positively. At that time, the exciting current IA increases but the other exciting current IB decreases. The same phenomenon takes place when the rotor tooth approaches the pole leftward. As a result, a braking force is effectively applied to the pulse motor by the induced voltages and the transient vibration of the motor is quickly damped.

Abstract: PURPOSE:To obtain a superconductive ceramic paste having low electrical resistance in applying to semiconductor devices or printed circuit boards, by adding metallic Cu powder to a superconductive ceramic paste using a high- temperature superconductive ceramics powder. CONSTITUTION:The aimed ceramic paste obtained by adding metallic Cu powder to high-temperature Tc superconductive ceramics expressed by the formula, such as Y-Ba-Cu-O based, La-Sr-Cu-O based or Sc-Ba-Cu-O based ceramics. The above-mentioned paste consists of a high-temperature superconductive ceramics powder and a dispersion medium for dispersing the afore-mentioned powder and imparting suitable handleability as a paste. The superconductive ceramic powder is used in an amount of preferably 60-90wt.% in the paste. The dispersion medium is constituted of a binder, plasticizer and high-boiling solvent. The electrical resistance of wiring a materials in a printed circuit board can be reduced to zero at the liquid N2 temperature of above by using the paste of this invention.

Title: Sample sucking device
Inventor: SASAKI TOSHIYUKI
IPC: G01N1/00
Filed: 1992-05-01
Abstract: PURPOSE:To surely prevent the suction of blood cell by stopping the suction of plasma or serums when a detection electrode with a lower end protruded from a first suction nozzle detects the surface of the blood cell while the plasma or serums are sucked through suction nozzles. CONSTITUTION:The impedance between a first and second suction nozzles 4 and 5 measured while a holder 7 is lowered changes when each nozzle reaches plasma or serums 2. The voltage value obtained by converting 13 the impedance is compared 14 and 15 with set values X and Y. When the voltage value is equal to the set value X, namely, when the voltage value is equal to the voltage of the plasma or serums 2, the voltage value is inputted to a CPU 9 and the CPU 9 stops the lowering of the holder 7 after a prescribed period of time has elapsed. Then, the CPU 9 actuates a first suction driving section 11 and the nozzle 4 sucks the plasma or serums 2. In such a state, the impedance between the nozzle 4 and a detection electrode 6 is measured and compared with a set value W after the impedance is converted 16 into a voltage value. As a result, the CPU 9 judges that the nozzle 4 will suck blood cell 3 and stops the plasma or serum sucking operation of the nozzle 4 by controlling the deriving section 11 when the front end of the electrode protruded downward from the nozzle 4 by a prescribed dimension L is detected reaching the blood 3.

Title: Optical recording medium and reproduction method therefor
Inventor: HARADA TOSHIO
IPC: G11B7/24065
Filed: 1994-05-26
Abstract: PURPOSE:To facilitate application to a medium other than a magneto-optical recording medium and to a mark edge recording without requiring a high optical intensity while realizing density recording/reproduction of information through super resolution effect by providing a mask layer containing photochromic color molecules. CONSTITUTION:A mask layer 12, a recording layer 13, a reflection layer 14, and a protective layer 15 are laminated sequentially on a transparent substrate 11 made of polycarbonate to form an optical recording medium. The mask layer 12 contains photochromic color molecules which absorb a reproduced light of corresponding wavelength to cause photochemical reaction thus developing a color. Transmission of the reproduced light is retarded in the colored region 3 and the reproduced light reaches the recording layer 13 only at the faded part in the first half part of a reproduced light spot 1. Consequently, a recorded mark 2 is read out at an effective reproduction spot 4 having smaller region than the reproduced light spot 1. Since super resolution effect is achieved, the line recording density is enhanced resulting in the high density recording/ reproduction of information.

Title: Cooling and heating apparatus
Inventor: YAMAZAKI TAKAI
IPC: F25B29/00
Filed: 1985-05-28
Abstract: PURPOSE:To decrease running costs, by forming and storing ice in a heat accumulating tank at the time of cooling by utilizing electric power at night, and storing warm water at the time of heating. CONSTITUTION:At the time of cooling, refrigerant is compressed to a saturated vapor pressure corresponding to a condensing temperature by a compressor 3, sent to a condenser 4 and liquefied. The pressure of the condensed liquid is reduced to the saturated vapor pressure corresponding to a temperature, which is 1-2 deg.C lower than the freezing point of brine in an expanding value. Thereafter, the liquid is atomized into a heat accumulating tank 1 through nozzles 7. The refrigerant liquid absorbs the heat from the brine and is evaporated. The refrigerant reaches the sucking side of the compressor. The heat of the brine in the heat accumulating tank 1 is absorbed by the vapor of the refrigerant liquid, and ice crystal is yielded in the brine. At the time of heating, cooling water (brine) used in the condenser 4 is sent to the heat accumulating tank 1 by a cooling water pump 9 and returned to the condenser 4 again. When the water passes the condenser 4, the heat of the refrigerant is absorbed and the temperature is increased. Therefore in the heat accumulating tank 1, the heat yielded in condensing the refrigerant is accumulated. The above described operation is conducted using midnight electric power service.

Title: Piezoelectric type finely moving element and finely positioning device using thereof
Inventor: HIGOMURA MAKOTO
IPC: G05D3/12
Filed: 1984-06-02
Abstract: PURPOSE:To aim at miniaturizing a semiconductor manufacturing device having a finely moving device, etc., by incorporating a pressure detecting piezoelectric element in a laminated type piezoelectric element so that the displacement of the finely moving device is feedback-controlled to a desired value in accordance with a voltage delivered from the pressure detecting piezoelectric element. CONSTITUTION:When a desired displacement value is given to a displacement-pressure transducer circuit 6, the output voltage 6 of the tranducer circuit 6 is amplified by a piezoelectric element driving voltage amplifier 8, and is then applied to a driving piezoelectric element 2a. Thereby a strain is generated in the piezoelectric element 2a to deform a parallel spring mechanism 1 so that a tool bed is finely displaced by a predetermined distance. At this time a pressure for deforming the parellel spring mechanism 1 is generated in a laminated type piezoelectric element 2, and therefore the voltage applied to the driving piezoelectric element 2a varies. Accordingly, the displacement value of the piezoelectric element 2 tends to come off from its desired value, however at this time a generated voltage in accordance with the generated pressure is detected by a voltage detecting amplifier 7 through a pressure detecting piezoelectric element 2b and an electrode 5. The output voltage of the amplifier 7 is fed-back to the voltage delivered from the transducer circuit 6 to control the voltage of the piezoelectric element 2a.

Abstract: PURPOSE: To prevent overturning and to change a direction by attaching shake stop fittings for which the upper part and lower part of two freely extendable and contractible and lockable lot bars are universally joined to the four corners of a device. CONSTITUTION: The base part of an upper fitting 101 and the upper part of the rod bar 103 are universally joined by an upper universal joint 102 and are mutually rotatable. The small lot bar 103 is inserted to the inner part of the large rod bar 105 and both are locked at a desired position when a lock fitting 104 is fastened.
