Title: Beam focus abnormality detector for laser beam machine
Inventor: MATSUNAGA MASAYUKI
IPC: B23K26/046
Filed: 1986-04-03
Abstract: PURPOSE:To improve detecting accuracy by providing a detector main body having plural temperature detection ends and detecting the abnormality via the temperature detected by the temperature detection ends. CONSTITUTION:The detector main body 10 provided with the plural temperature detection ends 12 is mated with a step part of a work table 8 and the positioning is performed. On this occasion, the detections ends are arranged fixedly on the detector main body 10 so that the tips of the detection ends are aligned with respect to a through hole 11 of laser beams 2. The laser beams 2 are projected and the radiant heat by the laser beams 2 is detected by the plural temperature ends such as thermocouples, etc., and compared with a preset normal detection output range. At this occasion, when a laser beam focus 7 is deviated, the detected temperature is different from a value at the normal time and the deviation of the focus 7 can be quickly detected. Accordingly, in this way, the abnormality detecting accuracy can be improved.

Title: Pipe fitting
Inventor: SUZUKI HIDEO
IPC: F16L37/40
Filed: 1995-03-31
Abstract: PURPOSE: To prevent the flow of fluid from being disturbed by forming a cylindrical body extending in the axial direction of a body at the rear end of a valve-element and arranging a spring to act a spring force against the valve element toward a valve seat inside the cylindrical body so that the spring is covered with the cylindrical body and not exposed directly to the inside of a plug body and a socket body. CONSTITUTION: A cylinder 25 is located behind a valve element structural body 23 on the axis of an inner hole 11 of a plug body 3, and formed integrally. Also the rear end of the cylinder 25 is open in order to insert a compressive spring 27. Then the compressive spring 27 is stored inside the cylinder 25 and a support hole 26a of a valve element support 26, and not exposed to the outside. By this, the compressive spring 27 used for a valve 4 is not exposed to the inner hole 11 of the plug body 3, and the cylinder 25 in which the compressive spring 27 is stored and the valve element support body 26 are exposed. Thus, because the compressive spring 27 is not present in the inner hole 11 of the plug body 3, fluid can flow through the inner hole 11 without being disturbed by the compressive coil spring 27.

Title: Cutter head for record disc
Inventor: KUROSE HIDEO
IPC: H04R9/16
Filed: 1979-06-18
Abstract: PURPOSE:To make light the cutter head and to increase the performance, by using the nitride ceramics for the delivery mechanism which delivers the driving force produced in the moving coil to the cutter stylus. CONSTITUTION:The drivers 181, 182 are coupled to the moving coils 111, 112 and the stereo signal fed to the moving coil is delivered to the cutter stylus 20 by means of a pair of delivery mechanism consisting of the couplers 191, 192 connected to the drivers. The delivery mechanism is formed with notride ceramics member of ultrahardness such as silicon nitride. By using nitride ceramics for the delivery mechanism, the oscillation system can be made light and the resonant frequency is higher and the fidelity of cutter head can remarkably be increased. Further, since the inner sound velocity is fast, the input signal to the moving coils can remarkably be reduced, allowing to increase the dynamic range.

Title: Light amplifying device by optical fiber
Inventor: NAKAZAWA MASATAKA
IPC: G02B6/00
Filed: 1983-04-27
Abstract: PURPOSE:To substantially enlarge a relay section by uniforming planes of polarization of the signal light and the pumping light by using the polarization retaining optical fibers to increase the light amplification gain. CONSTITUTION:The output light of the signal light source 1 and the output of the pumping light source 2 are mixed by a wave compounding device 3 and pass through a light amplifying fiber 9 and pass through a filter 5 to intercept the pumping light and extract only signal light. This signal light is coupled with the transmission optical fiber not shown in the figure in an injection end 6. The basic constitution is equal to the conventional one, but the feature is in that a polarization retaining optical fiber is used for a light amplifying fiber 9. In the polarization retaining optical fiber, a difference DELTAbeta of the propagation constant of two crossing polarization modes HE11X and HE11Y is enlarged and only one of these modes HE11X and HE11Y is propagated. By using the polarization retaining optical fiber, the signal light 7 and the pumping light 8 carry out the mutual action strongly over the whole length of the optical fiber 9 to substantially amplify the signal light 7.

Title: Braking force controller for vehicle
Inventor: OKAZAKI HARUKI
IPC: B60T8/48
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To restrain wasteful pump extended driving by estimating the remaining amount of brake fluid in a reservoir based on the operating status of an ABS control unit, and changing pump driving time after the completion of ABS control based on the estimation. SOLUTION: An estimating means is mounted, which estimates the remaining amount of brake fluid in a reservoir based on the output signal of a control block 62b and the monitor signal or the like of a monitor block 62c, in other words, the operating status of the ABS control unit 62. As a result, pump extended driving after the completion of ABS control is minimized for restraint of wasteful energy consumption and noise generation, therefore, it is possible to conduct ABS control without any trouble.

Title: Section information revision method in collection system of data corresponding to telephone set
Inventor: OSHIMA KENICHI
IPC: H04M11/00
Filed: 1989-03-30
Abstract: PURPOSE:To relieve a load given to a maintenance personnel by devising the method such that rewrite of a content (section information) of a section reference table is implemented from each telephone set even not from a maintenance console. CONSTITUTION:Sets of section information X1, Y1, X2, Y2... are expressed as, e.g. series numbers of 01, 02,.... Since the sets of section information are expressed by numerals because of series numbers, the section information is noticed to a private branch exchange(PBX) by using dial or pushbutton from each terminal equipment. The rewrite of section information in a section reference table 13 is attained by preparing only a conversion table converting the informed number (serial number) into the section information by the PBX. Thus, the rewrite of the section information is attained from a transferred telephone set side to the section reference table 13. Thus, the load of the rewrite in the maintenance console is relieved.

Title: Lighting system and liquid crystal display device
IPC: G09F9/00
Filed: 1992-03-31
Abstract: PURPOSE:To provide a liquid crystal display device preventing the nonuniformity of brightness generated on the irradiation face. CONSTITUTION:When fluorescent lamps 14 are lit up, prism bodies 21 are irradiated by light. In the prism bodies 21, the index of light refraction is larger toward a base body 11, and the irradiation light from each fluoresent lamp 14 is refracted in such a way as to irradiate a light diffuse transmission member 23 uniformly up to the middle part between the fluorescent lamps 14, 14. Efficient irradiation can be obtained because of the short optical path distance to irradiate the center of an irradiation opening part 13. The apparent luminescence face is formed on the light diffuse transmission member 23, and it is hard to generate the nonuniformity of light on this light diffuse transmission member 23. A liquid crystal display body 24 is also irradiated by uniform irradiation light from the back face, so that brightness can be made uniform.
