Abstract: PURPOSE: To allow excellent centering at the time of clamping an optical disk in a turn table by giving energizing force in a mutually approaching direction to a centering member freely slidably provided in a spindle shaft and to a clamp member provided opposing to it. CONSTITUTION: The spindle shaft 77 is freely slidably externally engaged with the centering member 92 which is engaged with the center hole 97 of a video disk 2 so as to execute centering to it against the shaft 77 and the turn table 86.

Title: Luster measuring device
Inventor: IGARI MOTOO
IPC: G01N21/55
Filed: 1981-09-03
Abstract: PURPOSE:To measure the luster of the surface of an object to be inspected exactly even in the case of the rugged state on the surface of said object having directional properties, by projecting and receiving a light on the surface of said object in all the directions of 360 deg. and measuring the amount of omnidirectional received light continuously. CONSTITUTION:When a cylindrical rotating shaft 6 is rotated while irradiating a light beam 12 from a light projecting device 4, the beam 12 is reflected at a  plane mirror 6 which is set at a prescribed angle of inclination, and is made  incident at 45 deg. angle to the crossing point P with an optical axis 5 on the  surface of the object to be inspected through the surface of an inner peripheral  mirror 7a of a cylindrical mirror 7. While, the reflecting light at the point P is  received by a photodetector 8 fixed at the back surface of the plane mirror 6  through the other surface area on the inner mirror surface 7a of the mirror 7.  This light receiving action is performed continuously in accordance with the  rotation of the mirror 6, and the luster degree is decided by making the voltage  output of the element 8 outputted through a rotor 10 and a brush 11 in all the  directions average.

Title: Optical head
Inventor: OMURA TAKUJI
IPC: G11B7/09
Filed: 1985-06-26
Abstract: PURPOSE:To obtain an optical head having a simple structure and a quick access time by attaching various optical elements to a substrate having a floating surface flat part and an escape part. CONSTITUTION:Various optical elements are attached to a substrate 16, and when a disk 19 rotates, the substrate 16 receives a positive pressure and floats up from the disk 19 by a prescribed minute quantity. By this prescribed floating quantity, when the disk is rotating, a distance between the disk 19 and a hologram lens 13 becomes constant. In this state, light which is emitted from a semiconductor laser 11 passes through a half mirror 12 and the hologram lens 13, and forms a focus just on the surface of an information carrier surface 20. The light which is reflected by the information carrier surface 20 is made incident on a four split detector 15 through the hologram lens 13, the half mirror 12, and an astigmatism generating lens 14. In this way, when the disk is rotating, a distance between the information carrier surface 20 and the hologram lens 13 can be made constant without providing a focus mechanism.

Title: Power supply
Inventor: KANBARA TAKASHI
IPC: H02M5/27
Filed: 1993-06-10
Abstract: PURPOSE:To block steep current flow upon polarity inversion of current at an inverter section. CONSTITUTION:The voltage from a DC power supply VS is converted into a DC voltage at a flyback type converter section 1. DC power thus converted is then inverted into AC power at an inverter section 2. The voltage across a capacitor C1 connected with the output of the inverter section 2 is fed, as a power supply voltage, to a load circuit 3. The inverter section 2 is provided with an impedance element Z for discharging the capacitor C1 through switching elements Q1, Q3 at the time of polarity inversion. Charges in the capacitor C1 are decreased by means of the impedance element Z at the time of polarity inversion thus suppressing the overcurrent flowing into the converter section 1 and the inverter section 2.

Title: Optical communication method
Inventor: TOBA HIROSHI
IPC: H04B10/278
Filed: 1987-06-05
Abstract: PURPOSE:To eliminate the need for addressing a transmission signal by using an optical multiplexer/demultiplexer as an optical branching/inserting device and assigning at least one optical frequency specific to each node. CONSTITUTION:Optical inserting devices 41-4n are optical multiplexers/ demultiplexers whose transmission frequency is fixed and optical inserting devices 51-5n are optical multiplexers/demultiplexers whose transmission frequency is variable. One frequency each (fi, fj, fk) is assigned to nodes 61-6n and the transmission frequency of the optical multiplexer/demultiplexer used as a branching device belonging to the node is fixed to its value. For example, in accessing the node 61 from the node 62, the transmission frequency of the optical multiplexer/demultiplexer 52 of the node 62 is tuned to the frequency fi at first, the light source frequency of the node 61 is set as the frequency fj and the optical multiplexer/demultiplexer 41 of the node 61 is set in advance to transmit only the frequency fi. Thus, the signal having the frequency fi sent from the node 62 is received selectively.

Title: Disk-shaped optical recording medium
Inventor: HASE FUMIO
IPC: G11B7/24073
Filed: 1984-07-06
Abstract: PURPOSE:To protect surely the data in a fixed information region consisting of a fixed program region and address region by forming the protective pits which are finer than the data pits of the tracks of said fixed information region and generate a high-frequency component to said tracks. CONSTITUTION:The laser beam 13 emitted from a laser generator 12 arrives at a medium 1 by passing through an optical modulator 14, a beam splitter 15, a projecting lens 16, a tracking mirror 17 and an objective lens 18. The illuminance of the beam 13 is high in the stage of recording and is low in the stage of reading. The beam 13 reflected from the medium 1 in either case is split by the beam splitter 15 and is passed through a photodetector 20, an amplifier 21 and a demodulating circuit 22, by which the beam is made into the reading out data. Whether the high-frequency component generated from the pits 10 is included in the data or not is detected by a high-frequency detecting circuit 23. The output from the generator 12 is decreased by a laser change-over circuit 24 when the high-frequency component is detected during writing. The irradiation of the beam 13 having the strong illuminance to the tracks 3 of the fixed program region 4 and address region 8 is thus obviated and said regions are safely protected.

Abstract: PROBLEM TO BE SOLVED: To reduce a loss of a recitifier circuit in a charging circuit of a storage battery. SOLUTION: In a step-up circuit 10 of a charging circuit, a coil 13 and a first switching element 14 are parallelly connected to a capacitor 12. To a gate terminal of the switching element 14, an oscillation circuit 15 is connected. A thermoelectric couple 21 is connected to an input terminal of the step-up circuit. To an output terminal between the coil and the switching element, a second switching element 22 for rectification is connected. A gate terminal of the switching element 22 is connected to the oscillation circuit through an inverter 23. The source-to-drain saturation voltage VDS of the switching element 22 is about 30100mv, so a loss in the voltage VDS is very much smaller than the forward voltage VF of conventional rectifier diodes and thereby a charging efficiency of the charging circuit can be remarkably increased.  By not operating the second switching element 22 when electromotive voltage is low, a back flow of current to the step-up circuit side from a storage battery can be prevented.
