Title: Measuring instrument for relative position of formed pit
Inventor: ITO YUJI
IPC: G11B7/26
Filed: 1989-05-02
Abstract: PURPOSE:To accurately and easily measure the relative position of a formed pit by measuring a time from a reference clock pit pulse generated by a clock pit pulse from an optical head on one side arranged precedingly in the rotational direction of an optical disk to the clock pit pulse from the optical head on the other side. CONSTITUTION:A reference trigger generation circuit 21 generates the reference clock pit pulse by the clock pit pulse from the optical head 17 on one side arranged precedingly in the rotational direction of the optical disk 11 out of two sets of optical heads 17 and 18. A window generation circuit 22 opens a detecting window for prescribed time after the lapse of prescribed time behind the reference clock pit pulse, and a reference clock generation circuit 24 generates a reference clock. The reference clock is counted during a time from the time when the reference clock pit pulse is generated from a reference trigger generation circuit 21 to the time when the clock pit pulse is generated from the optical head 18 on the other side while the detecting window of the window generation circuit 22 is opened, and the relative position of each clock pit can be calculated. Thereby, it is possible to accurately and easily measure the relative position of the formed pit.

Title: Light-activated thyristor and its manufacture
Inventor: MIYAMOTO MASATO
IPC: H01L29/747
Filed: 1994-05-26
Abstract: PURPOSE:To positively turn off a light-activated thyristor by stopping the application of light and at the same time simplify manufacturing process. CONSTITUTION:A resistor R and an insulated-gate transistor Q1 are connected in parallel between a cathode gate region 4 of a thyristor SCR consisting of PNPN four-layer structure and a cathode region 5. A series circuit of two diodes D1 and D2 is connected between the gate of the insulated-gate transistor Q1 and the cathode region 5 of the thyristor SCR. The gate of the insulated-gate transistor Q1 and a voltage sensing region 6 of the thyristor SCR are connected. By connecting two diodes D1 and D2, a transition reduction rate DELTARSD of the resistance between the source and drain of the insulated-gate transistor Q1 is reduced to 1/2 as compared with that of a conventional configuration, thus easily bypassing leak current IL generated inside the thyristor SCR and positively turning off the thyristor SCR when the application of light is stopped.

Abstract: PURPOSE: To protect the iron of the feed water heaters and drain pipes of thermal power plant or the like from corrosion, by introducing a feed water treating agent such as ammonia from the heated steam pipes and drain pipes of te heaters and the heaters themselves.  
     CONSTITUTION: The feed water treating agent, introduced into a high-pressure feed water heated steam pipe 14A from a pump 20 through a pipe 21, flows into the main body container 27 of a feed water heatr 11 and is then mixed with the drain of the heater. The mixture flows into a low-pressure feed water heater 10, through a drain pipe 15A. At that time, the treating agent introduced into the drain pipe 15A flows into the heater 10, too. Since the treating agent introduced into the high pressure steam pipes 14AW14D and the high-pressure feed water heater drain pipes 15A W15C flows to the low-pressure feed water heaters 8W11 sequentially, the iron on the inside surfaces of the drain pipes 15AW15C and the main body containers 27 of the heaters 8W11 is protected fom being eroded by steam etc

Title: Valve device
Inventor: YUKIHIRO MAKOTO
IPC: F16K41/02
Filed: 1985-05-27
Abstract: PURPOSE:To operate a valve without an increase in diameter of a valve stem of a packing portion more than required by providing a self-sealing heat-resisting packing adapted to operate only at the time of an abnormal high temperature such as a fire or the like outside the conventional packing for sealing a fluid round the valve stem to be used in combination therewith. CONSTITUTION:In the normal use condition, a fluid between a valve stem 25 and a valve cover 16 is sealed by a soft packing 37. In such a condition, a heat-resisting packing 44 is not pressed to the valve stem 25 not to be damaged. When a valve is subjected to a high temperature such as a fire, an annular disc 39 is first fused due to a temperature rise of the valve to flow out to an escape space 40, so that a packing presser loses the axial support force, and the heat-resisting packing 44 mounted on the forward end of a taper projection 38 is forced to slide along the taper surface of a taper seal hole portion 42 and pushed up by the fluid pressure applied to the cross-sectional area of the soft packing 35, thereby to seal a fluid round the valve stem 25.

Abstract: PURPOSE:To prevent parasitic motion by supporting a weight member in a housing freely floatably, and by fixing this housing at an adequate position in a pickup system. CONSTITUTION:Near the center of the inside bottom part 10A of a main body 10, a bar body 12 is stood and the nearly plane bottom part 10A is applied with lubricating oil 14, through which an annular weight member 13 is supported. The weight member has about 200mg-5g weight and about 1cm diameter. A fixing device 15 of an adhesive tape is provided at the outside bottom part 10B of the main body 10 and stuck, for example, to the top surface, etc., of a head shell. Consequently, the weight member sets itself in motion repulsing parasitic motion to absorb energy, which corresponds to the speed of the parasitic motion, by its motion proportional to the speed. Since the energy of the parasitic motion varies a little with stylus force, the weight member is varied necessarily corresponding the stylus force.

Title: Polarizing element
Inventor: TANABE YUZURU
IPC: G02F1/1335
Filed: 1996-05-08
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive polarizing element which can be easily processed by filling a space between substrates with an optically anisotropic material into a laminar state which makes an angle to incident light. SOLUTION: An optically anisotropic material 2 such as a liquid crystal is held between two transparent substrates 1, 1 a so that the interfaces of the material 2 and the substrate 1 are tilted to incident light. When laser light 3 of 650nm wavelength enters the polarizing element, polarized light having a parallel polarizing plane to this paper, namely, P-polarized light 4 transmits straight through the element since the refractive index is equal, while polarized light having a perpendicular polarizing plane to the paper, namely S-polarized light 5 is refracted and outgoes from the position 8μm displaced from the outgoing position of the P-polarized light. Thereby, the incident light is accurately divided into components of different polarizing directions by the polarizing element.  The polarizing element can be formed only by filling the space between transparent substrates such as glass supporting bodies with an optically anisotropic material 2 such as a liquid crystal polymer so that the material 2 is tilted to the incident light.
