Patent JP-S6042862-A (JP)
Title: Photo-driven semiconductor device
Inventor: YOSHIDA MOICHI
IPC: H01L31/111
Filed: 1983-08-17
Abstract: PURPOSE:To enable to rapidly and easily perform the positional fixing of a semiconductor element by a method wherein an insulation cylinder is partly put in close contact with a coating resin protecting the peripheral edge of the element. CONSTITUTION:The insulation cylinder 5 constituting the package is provided with a ring-form step 5a in close contact with the surface circumference of the coating resin 7 adhered to the peripheral edge of the semiconductor element 1. In such a package, when the positioning of an electrode 3 and the photo output end of a light guide 6 which are fixed to the cylinder 5 and the light trigger photo receiving part of the element 1 is carried out, because of the contact of the step 5a with the resin 7, the outer peripheral surface of a conductor 2, the resin 7, and the step 5a form a space with a U-shaped cross-section. Therefore, since a hardened type resin 8 is cast into the U-shaped space after the positioning of the element 1, the resin 8 does not flow out. Accordingly, the positional slippage of the element 1 accompanying the flowout of the resin 8 does not occure, and then the reliability of the package can be improved.

Title: Piston mechanism for drive of cam plate
Inventor: KOUDA TOSHIHIDE
IPC: F04B9/04
Filed: 1983-08-17
Abstract: PURPOSE:To prevent excessive compression by furnishing a cam plate on a rotary shaft, placing a cam follower bearing in pressure contact with the peripheral surface of said cam plate, and by fitting the cam follower bearing on the cam follower center shaft connected with piston side. CONSTITUTION:A cam plate 10 with selectivity of any desired outside shape is furnished on a rotary shaft 9, and a cam follower bearing 14 coupled with a piston 6 is put in pressure contact by spring 16 with the peripheral surface of this cam plate 10. Thereby the rising speed of the piston 6 immediately before gas discharge out of the cylinder 7 is retarded to eliminate violent emission of the gas, which will contribute to uniformalization of the amount of gas emission. Thus excessive compression can be relieved.

Patent JP-S63314728-A (JP)
Title: Circuit breaker
Inventor: TAKAHASHI MITSUGI
IPC: H01H33/10
Filed: 1987-06-17
Abstract: PURPOSE:To obtain excellent high voltage shutoff performance by arranging a plural number of lower arc extinguishing grids below a top arc extinguishing grid, and providing the top arc extinguishing grid with an intermediate electrode which opposes an arc horn when the electrode closes. CONSTITUTION:Arc produced by the opening of contact points 3, 4 is absorbed in the direction of arc absorbing grids 6, 13 and the foot of the arc is attracted to a runner 14 and a horn 9. Since the horn 9 is located in a cut 13a of the top arc extinguishing grid 13 and the gap between its rim and the arc is very small, magnetic attraction force of the grid 13 is very strong. As a result, the foot of the arc shifts instantaneously to the tip of the horn 9 and the arc is divided between the horn 9 and an electrode 11, and between the grid 13 and the runner 14, and separates from the space formed between the contact points 3, 4. As a result, insulation near contact points of a small insulation distance after a current becoming zero is quickly recovered. Since an arc voltage between the horn 9, grid 13, and the runner is high, high voltage shutoff is possible.

Filed: 1984-07-20
Abstract: PURPOSE:To increase the transmission efficiency of electric power, to design easily a matching circuit, and to improve the stability by providing a capacitor for impedance matching, a high frequency coil, and a balance-unbalance converter. CONSTITUTION:The impedance of the high frequency coils is set to, for example, 200OMEGA equivalently through variable capacitors 5 and 6 for impedance matching. Then, they are coupled with a high frequency transmitter receiver having the balanced impedance by the balance-unbalance converter 7 which operates for the impedance conversion of one couple 4, and the impedance when the high frequency coil side is viewed from an input/output terminal 4 is 50OMEGA. The input/output impedance of the high frequency transmitter receiver is normally 50OMEGA, so impedance matching is therefore performed. This method is effective undoubtedly even when te impedance is not 50OMEGA, and constants of the variable capacitors are only varied. The converter 7 is indispensable to the maximization of the transmission efficiency of high frequency energy.

Title: Floor heating panel
Inventor: SASAKI TAKASHI
IPC: F24D3/16
Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To hardly generate a curvature irrespective of a wooden plate body by bonding and connecting integrally a flexible thin plate to the surface of the plate body on which a plurality of grooves are formed and using this surface as a bottom surface. SOLUTION: For example, a plurality of grooves 2 with width of 9 mm and depth of 9 mm are formed in the longitudinal direction of a wooden plate body 1 whose thickness is 12 mm. Conduits 3 whose outside diameter is 8.5 mm are buried in the grooves 2. A flexible thin plate 4 composed of a laminated body of an aluminium foil/nonwoven cloth/thermoplastic resin sheet is bonded to the surface on which the grooves 2 are opened. When a floor heating panel is laid, the surface to which the flexible thin plate 4 is bonded is directed downward and the surface to which the flexible thin plate 4 is not bonded is directed upward. When the floor heating panel is laud in this manner, the skin of the wooden plate body 1 is exposed. Since the entire surface of the plate body 1 absorbs or discharges water (moisture) uniformly depending on temperature change in an environment in which the floor heating panel is laid, a curvature is not partly generated.

Title: Production of optical filter
Inventor: KOTANI KYOKO
IPC: G02B5/20
Filed: 1998-06-02
Abstract: PROBLEM TO BE SOLVED: To make it possible to control the ratio of grating writing portion (refractive index modulation portions) by changing the positional relation during grating writing, thereby changing the refractive index modulation points. SOLUTION: When the positional relation between a phase mask 6 and a photosensitive fiber 10 is provided with an inclination, since the photosensitive fiber 10 crosses the direction diagonal to the direction where the intensity of diffracted light 8 is intensified, the period of the portions, where the refractive index changes, is made wider than when the fiber is installed in parallel therewith (1/2 of the period (Λ) of the phase mask). The spread of the period is equal with respect to the extension direction of the photosensitive fiber 10. When the end on the opposite side is fixed and the phase mask 6 and a fiber holder are provided with similar inclination, the offset symmetrical with the previous case occurs. Only the ratio of the refractive index modulation portions (refractive index change parts 12) is thus changed without changing the period of the gratings.

Abstract: PURPOSE:To facilitate the control of the ratio of Bi to Sb and to facilitate the production of sensors equipped with a desire marginal wavelength by a method wherein Bi and Sb formed into films not thicker than de Broglie wavelengths are stacked up one upon another. CONSTITUTION:An infrared sensor of this design consists of Bi thin films 3 and Sb thin films 4 stacked up one after another and is provided with leads 11. The thickness of the Bi thin films 3 and Sb thin films 4 should be not more than de Broglie wavelengths in the respective materials (615Angstrom  for Bi and 157Angstrom  for Sb), preferably not more than 1/10 of the wavelengths. Further, the total thickness of the Sb thin films 4 should be 10-25% of the thickness of the entire sensor. With the thicknesses of Bi thin films 3 and Sb thin films 4 being not more than de Broglie wavelengths, the sensor may approximate a solid solution of Bi and Sb in band structure, which produces an infrared sensor presenting a direct transition type band structure when Sb occupies 10-25%. A change in the percentage of Sb results in a change in the margin of detectable wavelength range.
