Title: Cylinder valve
Inventor: KOYAMA FUMIO
IPC: F16K15/14
Filed: 1981-10-02
Abstract: PURPOSE:To decrease the inclination of a valve plate and to reduce stress of the valve plate, by inserting a guide ring provided with a guide surface having a wider width than thickness of the valve plate into a guide hole of the valve plate. CONSTITUTION:Width of a guide surface (inner circumferential surface) of a guide ring 7 is constituted larger than the thickness of a valve plate 1, and the valve plate 1 is installed on a guide part 3a of a valve bolt 3 through the guide ring 7. A gap which is naturally necessary for a smooth action of the valve plate 1 is formed between a guide surface of the guide ring 7 and the guide part 3a of the valve bolt 3, but the valve plate 1 guided by the guide part 3a without giving a little inclination is ascended or descended as the width of the guide surface of the guide ring 7 is constituted large.

Title: Optical disc device
Inventor: KANEDA NORIYA
IPC: G02B7/28
Filed: 1983-08-29
Abstract: PURPOSE:To prevent malfunction at the lead-in time of automatic focusing control by providing the titled device with stoppers for restricting the movement of an objective lens. CONSTITUTION:A stopper 61 for determining the lower limit position of an objective lens and a stopper 62 for determining the upper limit position are formed to locate the focal position of the objective lens at the shunting time in an optical disc base material 11. At the lead-in time to automatic focusing, the moving range of the objective lens is reduced less than twice the thickness of the optical disc base material 11 so that the focal position of the objective lens does not cross the surface of the optical disc base material 11. Since the opposite side of the recording side 12 of the optical disc base material 11 is not detected, a differential amplifier can output only the S-shaped characteristics obtained from the real recording side 12. Therefore, the focal position of the objective lens can be prevented from being set in a side other than the recording side.

Title: Manufacture of color filter and the color filter
Inventor: TAKAHASHI HIROKI
IPC: G02B5/20
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To save liquid by making the film thickness of pigment dispersed resist uniform while suppressing the formation, sticking, etc., of foreign matter. SOLUTION: A wire bar 54 is formed by winding a rod 54a spirally with a stainless steel thin wire 54b. The wire bar 54 is rotated to gather pigment- dispersed resist in recessed parts 56 formed between adjacent thin wires 54b and apply it to an upper substrate 11, and processes for exposure, development, etc., are performed to form a colored layer. The width of the area where the thin wire 54b is wound is made wide and the wire bar is rotated to apply a protecting agent gathered in the recessed parts 56 to the upper substrate 11 where the colored layer is formed, thus forming a protection layer more widely than the colored layer. Liquid of the pigment-dispersed resist can be saved.  Even if the pigment-dispersed resist is left at the periphery part of the upper substrate 11, the remaining resist is covered with the protection layer, so the generation of dust and foreign matter due to the residue of the pigment-dispersed resist or unevenness like liquid drooping can be suppressed.

Title: Rolling diaphragm
Inventor: KITA YASUO
IPC: F16J3/06
Filed: 1982-09-09
Abstract: PURPOSE:To achieve smooth rolling by making the rigidity at the rolling section of a rolling diaphragm for partitioning a cylinder having non-circular cross- section into two to be low at the portion having small apparent end face curvature while to be high at the portion having large curvature. CONSTITUTION:A cylinder 40 is formed to have non-circular cross-section or oval cross-section, for example, where the inserted piston 30 is formed to have similar cross-section with that of the cylinder 40. A diaphragm 10 is supported at the central portion by the piston 30 while at the outermost circumference by the cylinder 40 to partition the cylinder 40 into two. Here the portion (alpha) of the rolling section of the diaphragm 10 having small apparent end face curvature is made thin to lower the rigidity while the portion (beta) having large curvature is made thick to increase the rigidity. Consequently the expansion/shrinkage performance at the portion (alpha) is improved to absorb the variation of the circumferential length while to suppress the circumferential motion due to said variation.

Title: Production of optical fiber preform
Inventor: HASEGAWA NORITO
IPC: C03B37/018
Filed: 1998-06-05
Abstract: PROBLEM TO BE SOLVED: To obtain an optical fiber preform through such process that the flame throwing angles of respective nozzle chips are made smaller as the outer diameter of a quartz tube shrinks due to heating so as to always envelop the quartz tube in good balance with the flame from the nozzle chips even if the tube is narrowed and prevent the tube from getting flat. SOLUTION: This optical fiber preform is obtained by the following process: the variable mechanism section 8 for nozzle chips 6 works as follows: a cylinder 12 actuates in response to control signals inputted into a control box 14 to effect extending/shrinking of a piston rod 13, thereby the nozzle chip bodies 7 swing in the arrow direction and the flame throwing angles α of the respective nozzle chips 6 are made variable; when the outer diameter of a quartz tube gradually gets smaller as a deposition process proceeds, the information is inputted into a control unit, which then calculates the flame throwing angles αof the respective nozzle chips 6 based on an arithmetic program and outputs the result toward the control box 14; based on the result, the piston rod 13 gradually shrinks, resulting in gradually smaller flame throwing angles α.

Filed: 1984-07-28
Abstract: PURPOSE:To perform super precise grinding by constructing such that the fluid pressure in static pressure pocket is regulated to set the inclination between a grinding wheel and a work and the cutting amount in micron order. CONSTITUTION:In order to set the relative inclination theta between a griding wheel 22 and the face to be machined of work, the pressure of working fluid to be fed respectively into first and second static pressure pocket 17, 18 is regulated to incline the upper face of the table 1 against the grinding wheel 22. While in order to regulate the micron order cutting, the fluid pressure in first pocket 17 provided in the upper face at the guide section 16 is differentiated from that in second pocket 18 provided in the lower face. Then the differential pressur is regulated to move a micron order table 12 up and down thus to set the cutting amount. Since the inclination between the grinding tool 22 and the work 13 and the micro cutting amount can be set quite accurately, precise grinding is achieved.

Filed: 1979-12-06
Abstract: PURPOSE:To carry out the control of operating mode automatically by recording another control signal in an address signal part of a recording medium of a video disk etc., and detecting it during reproduction and controlling the operating mode automatically. CONSTITUTION:A sequential video information has 54,000 in number from a recording track 10 corresponding to the first TV frame to a recording track 11 of the final TV frame. Frame numbers from ''00001'' to ''54,000'' are given in order from the first frame, the respective signals are recorded as address signals of binary signal type during blanking period and used for the information retrieval. Accordingly, the difference of numbers corresponding to the adjacent tracks during the reproduction is always 1, while the difference of the signal corresponding to the address signal having no program information is always 0. Therefore, if this difference is detected, the information retrieval and address signals other than it can be discriminated and the latter is used for the operating mode. By such construction, the control of the operating mode is automatically carried out.
