IPC: H01S5/323
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To improve the adhesive property of a light-emitting chip by performing the die bonding of a light-emitting chip such that a first thin film containing a metal whose electronegativity is at a specific value is formed at a second, main surface side to a support via a conductive adhesive, while a first thin film faces opposite a support surface. SOLUTION: A double heterostructure, where an n-type layer 2, an active layer 3, and a p-type layer 4 are laminated successively, is provided on the first main surface of an oxide substrate 1, and an area above the p-type layer 4 is formed in a ridge shape, thus centering emission at the active layer 3 that is equivalent to an area below a p-type electrode 11. A light-emitting chip is die-bonded to a heat sink which is a support 30, while its surface faces upward via a conductive adhesive 23. A first thin film 21, made of metal such as Ti whose electronegativity is less than 2.0 is formed at the second main surface side of the oxide substrate 1. By forming the first thin film 21, the adhesive property between the oxide substrate 1 and the conductive adhesive 23 is improved, thus enhancing the adhesion property of the light-emitting chip.

Abstract: PURPOSE:To effectively eliminate the effect of the chromatic aberration of an image forming optical system on two-color image recording by setting the image forming optical system based on one laser light flux as a reference, and the beam waist of the other laser light flux large. CONSTITUTION:The image forming optical system 5 is set, based on one laser light flux as the reference, and the beam waist of the other laser light flux is set large, in two laser light fluxes from light source devices 1A and 1B, having different wavelengths.

Filed: 1989-10-06
Abstract: PURPOSE:To sufficiently lessen curvature of radius of a curled portion while securing the thickness of a rim portion sufficiently to make it possible to apply the rim to a wheel having a high pressure tire by forming the thickness of the curled portion in a flange portion thinner than the thickness of the other rim portion. CONSTITUTION:A light alloy made laminated rim is formed by curling inwards the flange portion 1 thereof. In this case, the thickness of the curled portion 2 is formed thinner than the other portion of the flange portion 1 and the thickness of the rim. At the time of curling, a plurality of V-shaped grooves are formed along a curve line in the curved portion of the curled portion 2. At the time of manufacturing, in a process wherein a light alloy made circle material is drawn deeply to press the rim and also just before a process wherein the flange portion 1 is curled, after the thickness of the curled portion 2 is cut to be thinned, two pressed and curled cups are joined. The flange portion 1 is thereby curled with a sufficiently small radius of curvature while the thickness of the rim is secured sufficiently.

Abstract: PURPOSE:To allow a sequence program to execute also difficult operation or the like by connecting an interface between a sequence program control part and a high level language control part so as to transmit/receive data. CONSTITUTION:A sequence program 3 is formed so that a start code or the like for high level language or data or the like required for operation is outputted to a position required for operation based upon the high level language.

Title: Manufacture for disk-shaped recording medium
Inventor: AKIMOTO YOSHIHIRO
IPC: B05D1/40
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain a recording medium which can suppress thickness nonuniformity of thin film and can suppress tilt angle errors and read errors, by maintaining a specified relationship between film thickness, viscosity, revolution per unit time of substrate and revolution time of a substrate of a thin film formed of a resin settable by ultraviolet rays. SOLUTION: The thickness T μm of a thin film formed of a resin settable by ultraviolet rays is set to satisfy T=(-13710+7687×ρ<1/2> )/(R×t<1/2> ). In the equation, a viscosity of the resin set with ultraviolet rays is ρ cps, a revolution per unit time of a substrate is R rpm, a revolution time of the substrate is (t) sec. When the thickness of the thin film of the resin set with ultraviolet rays is not smaller than 100 μm, a thickness irregularity of the thin film of the relatively large thickness, i.e., not smaller than 100 μm is restricted to not larger than ±5% if the viscosity of the resin at 25 deg.C is 1400 cps or larger and the resin is applied only once. Good productivity is achieved.  The viscosity is enhanced by increasing a quantity of low molecular polymers, whereby cross- linking performance is lowered, a Young's modulus and a shrinkage percentage are reduced and a tilt angle can be suppressed.

Title: Electric brake system
Inventor: KUBOTA MASAHIRO
IPC: B60T13/74
Filed: 1999-09-17
Abstract: PROBLEM TO BE SOLVED: To ensure given deceleration according to the travel of brake pedals despite of a change in the coefficient of friction of brake pads, prevent an overload on motor due to a reduction in the coefficient of friction, and warn the driver about the reduction in the coefficient of friction. SOLUTION: A gain as the function of pedal travel and motor driving current is corrected to bring actual deceleration to a given level in accordance with the pedal travel, and the motor is driven accordingly, so that given deceleration is ensured according to the pedal travel despite of a change in the coefficient of friction. The coefficient of friction is estimated on the basis of the actual deceleration and motor driving current, and a proof motor current Ia to offer proof deceleration Ga is detected. If the proof motor current Ia exceeds a maximal motor current Imax, the function expression is corrected so that the motor current Im changes below the maximal motor current Imax in accordance with the pedal travel. In this state, deceleration according to the pedal travel is no longer obtainable, which notifies the driver about the reduction in the coefficient of friction.

Title: Reel for packaging electronic part
Inventor: YOKOYAMA MASAKI
IPC: H01G13/00
Filed: 1989-10-11
Abstract: PURPOSE:To reduce space between the turns of wound embossing tape and prevent reverse winding thereof by a method wherein a reel is provided with a groove part into which the beginning part of the embossing tape is inserted, the width of the groove part is made greater than the height of the tape recess and one side of a groove exit is provided with a stepped part suffuciently high to permit the first turn of a part of the embossing tape. CONSTITUTION:A beginning part 11a of embossing tape 11 is inserted into a groove part 17 of a reel 15 and the embossing tape 11 is wound with a part 11b of its first turn extending along a stepped part 18 from the exit of the groove part 17, successively rolled up into form of a roll. Since the width of the groove part 17 is greater than the height of the recess part 12 of the embossing tape 11, the beginning part 11a can be inserted smoothly into the groove part. The reel 15 is provided at one side of the exit of the groove part 17 with a stepped part 18 sufficiently high to permit the first turn of the part 11b from the beginning part 11a. For this reason, the second and subsequent turns of the embossing tape 11 are made nearly circular, thereby leaving little space between each turn of the embossing tape 11 and preventing reverse winding thereof.
