IPC: A61B1/00
Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent a tube from being damaged because the tube is caught between articulate rings of a bent pipe portion by coating an optical fiber bundle by double flexible tubes within the bent pipe portion and excising a part on a side facing an outer edge of the bent pipe portion of the flexible tube in a region adjacent to a distal end main body within the bent pipe part. SOLUTION: In a flexible inserting portion constituted by successively connecting a bent pipe part 3 and a distal end main body 4 with a distal side of a flexible pipe portion, an optical fiber bundle 8 for illumination in which an incident tip part is connected with a light source device is passed. This optical fiber bundle 8 is coated with a flexible protective tube 8. In a part located within the bent pipe portion 3, the outside of the protective tube 81 is coated with a flexible reinforcing tube 82. The bent pipe portion 3 is formed by connecting a plurality of articulate rings 31 so as to be freely tiltable and the part of the reinforcing tube 82 on a side facing inner peripheral surfaces of these articulate rings 31 is excised. As a result, even if the bent pipe portion 3 is bent and articulate rings 31 adjacent each other are abutted, the reinforcing tube 82 is prevented from being caught between the articulate rings 31.

Title: Thermosensitive recording material and recording method
Inventor: SAKAMAKI TERUO
IPC: B41M5/26
Filed: 1989-08-02
Abstract: PURPOSE:To easily perform printing by a simple recording apparatus and to naturally erase recording data by standing by using a redox dye colorless in a reduced state and forming a color in an oxidized state as the dye forming a recording layer to preliminarily set the same to a reduced state by a reducing agent. CONSTITUTION:A redox dye discolored (developed and erased in color) in an oxidized state-reduced state and a reducing agent are infiltrated in a base material 1 to from a recording layer. When the redox dye is methylene blue, L- ascorbic acid is pref. used as the reducing agent because the redox potential of L-ascorbic acid becomes lower than that of methylene blue within a range of pH 4 or less. When the base material 1 impregnated with the recording layer is heated by a thermal head 4, the heated region forms a color to print a character 5. The printed character 5 is returned to the original colorless state by standing to becomes the same color as a ground color 6 and, as a result, recording data is naturally erased.

Inventor: SAITO JUNJI
IPC: H01L21/20
Filed: 1988-08-16
Abstract: PURPOSE:To electrically isolate a substrate from an active region also in a longitudinal direction, to prevent an electrical interference between semiconductor devices from being caused and to enhance an integration density by a method wherein a compound semiconductor interlayer isolation layer where the surface of the substrate has been supplied excessively with arsenic is grown, ions of oxygen are implanted selectively from the surface and a highresistance isolation layer reaching the compound semiconductor interlayer isolation layer is formed. CONSTITUTION:A semiinsulating GaAs substrate 1 is attached to a susceptor 15 in a crystal growth chamber 11 at an MBE apparatus; a shutter 18C of a first As molecular beam source furnace 17 is opened; while the substrate is being irradiated with an As molecular beam, a temperature of the substrate 1 is raised to, e.g., 750 deg.C; a thermal etching operation is executed for about three minutes. When this thermal etching operation is executed, an interface level between the substrate 1 and a semiconductor layer to be grown on it amounts to about 10<11>cm<-2>, and is reduced by about one digit as compared with a conventional one; even when a buffer layer is formed to be thin, a compound semiconductor layer becomes of good quality. An active layer 3, an electron supply layer 4 and a contact layer 5 are grown one after another on it; after that, oxygen is implanted selectively; an interelement isolation layer 7 is formed.

Title: Wiper arm and vehicular wiper
Inventor: TERAI TADAYOSHI
IPC: B60S1/34
Filed: 1997-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a wiper arm and vehicular wiper which can remarkably reduce the wind noise caused when a vehicle is traveling. SOLUTION: A wiper arm 12 of vehicular wiper 10 is equipped with a retainer 16. A pair of side walls 18, 20 constituting the retainer 16 and overhanging to such a direction as to allow their leading edge sections 18A, 20A to approach each other, is formed into a section of an inverted triangle as a whole. Further, the height to an upper wall 22 of the leading edge section 20A which is located downstream of a relative air flow, is set lower than that of the leading edge section 18A which is located up stream. This arrangement allows the relative air flow to flow along smoothly from the side wall 18 to the side wall 20 without becoming a turbulent flow, and a vortex flow hardly occurs in the rear of the side wall 18. Therefore, the vortex flow does not hit the side wall 20, so the cavity tone is not caused, and further, wind noise due to the vortex flow itself does not occur either.

Abstract: PURPOSE:To reduce a ripple of a signal at a pass band due to a TTE by increasing the impedance considerably higher than that of a conventional converter so that the electric reflection in the surface acoustic wave converter and a termination electric circuit is made less when the surface acoustic wave filter is formed. CONSTITUTION:A regular weighting coefficient is not applied to all of 100 taps in the 1st embodiment, but no weighting coefficient processing is applied to taps whose numbers are (3m-1) and 3m (m is a positive integer) and the regular weighting coefficient processing is applied only to taps whose tap numbers are (3m-2) (where 3m-2<=n). That is, since the (n) is set to 100, the number of taps subject to weighting coefficient application are '1, 4, 7, 10,...100' and the application of the weight coefficient to number of taps (3m-1) and 3m is culled out.

Abstract: PURPOSE:To decrease sectional defect parts and to improve a yield by constituting the above device in such a manner that the parts near both front and rear ends of an extruded shape material clamped at both ends by both front and rear clamping members are mounted on shape holding members thereof, by which the shape of the extruded shape material is maintained.

The transfer of the deformation of the side wall parts crushed by the clamping members to the intermediate part of the extruded shape material does not arise even if the extruded shape material is pulled in a longitudinal direction. The deformation in the parts near both front and rear end of the extruded shape material is minimized and the sectional defect parts of the extruded shape material are decreased. The amt. to be cropped at both front and rear end parts of the extruded shape material is decreased in this way and the yield is improved. The fluctuations in the size and shape are decreased and the need for a leveling operation is eliminated.

Title: Method for etching pressure control in dryetching device
Inventor: ONO YASUYUKI
IPC: H01L21/302
Filed: 1986-08-29
Abstract: PURPOSE:To cut down the time for stabilizing the pressure in a vacuum vessle by a method wherein the opening degree of a variable throttle valve is set up at specified value to control the pressure in vacuum vessel at a specified value, later the pressure value is monitored to adjust the opening degree of variable throttle valve to real time. CONSTITUTION:In order to specify the etching pressure of a reactive gas led from a gas leading-in pipe 5 to a vacuum vessel 1, the opening degree of a variable throttle valve 9 is arbitrarily set up by a pressure controller 8 to lead the reactive gas in the vacuum vessel 1. At this time, the opening degree of throttle valve 9 is kept constant. Later, when the pressure in vacuum vessel 1 monitored by a vacuum gauge reaches within, e.g., + or -20% (to be set up arbitrarily) of the set up pressure, the pressure value in vacuum vessel 1 monitored by the vacuum gauge 7 is inputted to the pressure controller 8 to adjust the opening degree of variable throttle valve 9 to real time for controlling the etching pressure of a semiconductor substrate 20. Through these procedures, the pressure in vacuum vessel reaches the specified set up pressure by two step pressure control process adopted to cut down the time for stabilizing the pressure in vacuum vessel 1.
