Title: Optical disk reproducing device and reproducing method
Inventor: AKIYAMA ATSUSHI
IPC: G11B7/00
Filed: 1999-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce noise included in reproduced signals. SOLUTION: A laser diode 20 emits laser beams having prescribed pulses to irradiate a magneto-optical disk 1 through an objective lens 3. The laser beams reflected from the disk 1 are separated into two polarized components and received by photodetectors 21 and 22. Current signals outputted from the photodetectors 21 and 22 are converted into voltage signals by I/V converters 5 and 6. Delay lines 7 and 8 delay the voltage signals based on the amount of the delay given by a controller 16. Delayed voltage signals S1 and S2 are inputted into a differential amplifier 9. The amplifier 9 outputs reproduced signals RF based on the signals S1 and S2. The signals RF pass a low pass filter 10 and is outputted to a noise detector 17. The controller 16 determines the amount of the delay in accordance with the output of the detector 17.

Title: Apparatus for liquid-phase epitaxial growth
Inventor: MIZUNO TSUGUNOBU
IPC: C30B19/06
Filed: 1993-01-12
Abstract: PURPOSE:To provide an apparatus for liquid-phase epitaxial growth capable of enlarging the area of a part having a uniform thickness of a single crystal film and simultaneously preventing a substrate from breaking in working by keeping the epitaxial growth surface of a ground substrate away from contact with a substrate holding jig. CONSTITUTION:A ground substrate 8 held by a substrate holding jig 9 is dipped in a crucible where a single crystal raw material is melted to carry out the epitaxial growth for a prescribed time. Thereby, a single crystal film is grown on the surface of the ground substrate. The substrate holding part has plural pawl parts (9e) for elastically holding the ground substrate from the outer peripheral direction. Since the pawl parts are kept in contact with only the peripheral surface of the ground substrate, the film thickness is not partially increased in the epitaxial growth surface of the ground substrate.

Title: Solar cell built-in camera
Inventor: SUZUKI RIYOUICHI
IPC: G03B17/02
Filed: 1978-02-24
Abstract: PURPOSE: To make it possible to extract an electromotive force, even if solar cell units are partially shielded, by short-circuiting the solar cell which is shielded by the hand of a photographer during photography so that it is rendered inoperative.  
     CONSTITUTION: A voltage level difference corresponding to the electromotive force of a solar cell is impressed between the two input terminals of comparator circuits 27 to 32 which are connected in parallel with the solar cells 21 to 26 connected in series. If, in this instance, the incident light upon the unit 24 is shielded so that the electromotive force of the unit 24 is lowered, the potential difference between the two terminals of that unit is reduced to substantial zero so that the output of the comparator circuit 30 is reduced to a lower level. Thus, a transistor 36 is rendered conductive so that the solar cell 24 is short-circuited through the emitter and collector of the transistor. As a result, the current to be generated by the remaining solar cells flows through the transistor 36 so that the secondary battey can be charged.

Abstract: PURPOSE:To prevent the generation of characteristic deterioration due to the repetition of overlight operation by forming a recording layer, which reversibly generating a phase change between a crystal phase and an amorphous phase corresponding to a condition of the irradiation energy of laser beam, from a specific ternary alloy. CONSTITUTION:A data recording medium is constituted of a substrate 1 and the recording layer 3 provided on the substrate 1 and reversibly generating a phase change between a crystal phase and an amorphous phase corresponding to a condition of the irradiation energy of laser beam when receiving the irradiation with laser beam. The recording layer is composed of a ternary alloy having the same composition as the alloy {(InSb)100-Y/200TeY/100}100-Z(InTe)Z (wherein Y and Z are set to 20<=Y<=45 and 0<=Z<=60 as well as Y=30 and 60<=Z<=80) of InTe and In50-X/2Sb50-X/2TeX (wherein X is 20<=X<=45). By this method, characteristics such that In50-X/2Sb50-X/2TeX rapidly crystallize and easily becomes amorphous even when the recording layer is irradiated with relatively low laser beam power and the stable amorphous characteristics possessed by InTe can be obtained. Since InTe has a stable composition, the composition of the ternary alloy is not changed even when overlight operation is repeated.

Filed: 1994-02-18
Abstract: PURPOSE:To recover quickly without the need of large electric power source and suppressing evaporation of freezing mixture when a permanent current switch is quenched by flowing a circulating current of permanent mode from a first electric power source and allowing a direct current to flow in the same direction as the circulating current to the permanent current switch from the second electric power source.

Connecting a bypass circuit 5 between lead wires 6, 6' that connect the permanent current switch 2 with the second electric power source 4, most of the circulating current is bypassed by the bypass circuit 5 when the permanent current switch 2 is quenched. Then allowing a current that is in the reverse direction with the bypass current and a little smaller than the bypass current to flow in the bypass circuit 5, the quenched permanent current switch 2 recovers the superconducting state.

Abstract: PURPOSE:To manufacture a high-sensitivity optical-information recording medium at low costs without increasing the number of manufacturing processes by a method wherein, when a recording layer is formed, a recording auxiliary layer is formed simultaneously by using a microcapsule containing a coating solution. CONSTITUTION:Microcapsules 4 which have been electrified to a recording pigment solution 3 in which an organic pigment has been dissolved in a solvent are dispersed on a transparent substrate 1; the solution is coated uniformly by a coating operation.
