Title: Optical information reader
Inventor: KAWAMURA YASUKAZU
IPC: G06K7/015
Filed: 1979-12-07
Abstract: PURPOSE: To realize a miniaturization with a simple mechanism and facilitate an easy mass production for an optical information reader, by controlling the focus position of the optical system by an actuator consisting of a unit of piezoelectric resonator pulse two coils attached to the resonator.  
     CONSTITUTION: The resonator 18 attached with the optical system block 17 is supported by the springs 25W32 in a vertical/horizontal movable way. The piezoelectric ceramics 19 and the yoke 20 are attached to the resonator 18, and the magnets 21 and 22 plus coils 22 and 23 are installed inside the magnets and coils. Thus an actuator is constituted. The actuator receives the horizontal and vertical forces when the current flowing to the two coils is in the same way and in the opposite way to each other respectively. In such constitution, a variation of phase occurs to the reflected light in case the optical system is out of the pattern track. This variation is detected by the phase wave detector 34, and the fixed current is supplied to the coils 23 and 24 by the compensation signal generated from the compensation signal generator 35 to give the vertical or horizontal vibration to the resonator 18. As a result, the optical system can be made to follow onto the pattern in an accurate way. This following is also possible even when the focus has some shift.

Title: Production of soft ferrite magnetic material
Inventor: NARUTANI SATORU
IPC: H01F1/34
Filed: 1991-06-28
Abstract: PURPOSE:To provide ferrite material of finer crystal grain and higher density compared with the conventional material and simplify the production by permitting a spinel ferrite powder aggregate to directly discharge and successively performing pressurization and conduction simultaneously. CONSTITUTION:A spinel ferrite powder aggregate is permitted to directly discharge and pressurization and conduction are simultaneously performed successively after the discharge. For example, 450wt.ppm CaCO3 and 100wt.ppm V2O5 are mixed to material whose basic composition has 52.75mol% Fe2O3, 26.50mol% MnO and 20.75mol% ZnO. The material is heat treated to be spinel in nitrogen atmosphere which contains 0.5vol.% oxygen at 1150 deg.C for two hours and is air-cooled in nitrogen. Then, the material is ground to allow 1.5mum average grain diameter, dried and filled in a 20mm diameter cylindrical cavity. The pressure is reduced to 0.5Torr, a superimposed direct current pulse voltage is applied for 45 seconds and plasma discharge is allowed. Then, 2000A current is conducted for 1.5 minutes, the material is cooled to 250 deg.C and released from a die.

Title: Optical recording medium
Inventor: ITO KAZUHIKO
IPC: G11B7/24062
Filed: 1986-07-07
Abstract: PURPOSE:To improve the storage stability by forming a rugged resin layer to the surface on the light reflecting layer of a base having the light reflecting layer so as to eliminate the deterioration in the recording characteristic. CONSTITUTION:A resin layer 8 having ruggedness 7 on the surface is formed on the light reflecting layer 6 formed to the base 5 of the optical recording medium 4. Then a laser light 9 is focused as a spot to a prescribed part of the surface of the optical recording medium 4 as above to deform the ruggedness of the part thereby changing the reflectance of light for desired recording. The quantity of the change in the light reflectance depends on the pitch 10, the height 11 and the tip shape of the ruggedness 7 formed on the surface of the resin layer 8 and in order to obtain a large light transmissivity change, the pitch 10 of the ruggedness 7 is preferably 0.5mum or below and the height 11 is preferably 0.4mum or below. Since no modification such as oxidation and corrosion exists different from a metallic thin film, no deterioration in the recording characteristic exists and the storage stability is also improved.

Abstract: PURPOSE:To improve the reliability of operation even when a pipeline, connecting an indoor unit to an outdoor unit, is long by a method wherein the outdoor unit and the indoor unit are provided with a pressure reducing device for cooling and a pressure reducing device for heating respectively while the pressure reducing effect of the pressure reducing device is changed by a temperature difference between temperature detectors provided on a pipeline connecting both pressure reducing devices in respective units. CONSTITUTION:When an operating mode is cooling upon trial running, an electronic expansion valve 4a is set at a predetermined opening degree So and another electronic expansion valve 4b is set at the maximum opening degree Smax. Upon heating, the expansion valve 4b is set at a predetermined opening degree So and the expansion valve 4a is set at the maximum opening degree Smax. An absolute temperature difference value is operated by a temperature difference operating device 12 from the detecting temperatures of temperature detectors 11a, 11b while the length L of a pipeline connecting an indoor unit to an outdoor unit is obtained from a diagram. The opening degree So of the expansion valve is operated by an electronic expansion valve opening degree determining device 13 from the temperature difference and the opening degree of the expansion valve 4a is set at So upon cooling while the opening degree of the expansion valve 4b is set at So upon heating. The length L of the pipeline is indicated by a light emission diode or the like and operation is shifted into the normal operation. A pressure reduction is set optimally in accordance with the length of the pipeline and, therefore, stabilized operation can be effected even when the length of the pipeline connecting indoor and outdoor units is long.

Title: Power factor improving circuit
Inventor: TOMIOKA ICHIRO
IPC: H02M3/155
Filed: 1994-06-17
Abstract: PURPOSE:To simply enhance the power factor of a control circuit by turning on a thyristor by the trigger signal of a current detector to control the duty factor of a switching element in a constant-current range. CONSTITUTION:Since a thyristor T is, when the potential generated at a current detecting resistor R1 by the conduction of a switching element 8 arrives at the gate trigger potential of the thyristor T, conducted to shunt a gate signal, a switching element S is stopped. Since the thyristor T is continuously conducted while there is a gate drive signal, the element S is not again conducted within this duty factor. Since the thyristor T is operated by a constant current via the resistor R1, the duty factor of the gate drive signal of the element S is so controlled as to follow up the input signal. As a result, the current density of a low voltage is raised via an inductor L, and the current follows up to the entire slope of the input voltage.

CONSTITUTION:The light 25 radiated from a radiating end surface 14a of a semiconductor laser 14 is made incident in the direction tilted in the track width direction by an angle theta against the direction vertical to an optical recording medium surface 28. Then the light 26 reflected by the track guide grooves (not shown where) formed continuously in the direction vertical to the surface 28 does not virtually return to the surface 14a and goes to the detecting surfaces of photodetectors 16a and 16b. The bias voltage is applied to both electrodes 18a and 18b for photodetectors set on the surfaces of both photodetectors 16a and 16b in the direction opposite to a common electrode 19. Therefore, the reflected light 26 is received by photodetectors 16a and 16b and a track signal can be obtained by the difference signal of output between both photodetectors 16a and 16b.
