Title: Semiconductor laser element and semiconductor laser device using it
Inventor: KOBAYASHI MASAMICHI
IPC: H01S5/00
Filed: 1983-07-01
Abstract: PURPOSE:To contrive the increase in reliability and the prolongation of life time of the titled device by the prevention of chip inclination and thereby improvement of thermal diffusion by a method wherein the neighborhood of both side edges of the chip is provided with a buried hetero junction in parallel with a buried hetero junction. CONSTITUTION:An N type GaAlAs 4, a GaAs active layer 5, a P type GaAlAs 6, and an N type GaAs 7 are superposed on an N type GaAs substrate 2. Mesa grooves 18 and 19 are provided, and a stripe 20 about 10mum wide and a wider auxiliary stripe 21 are formed. The pitch of the stripe 21 is about 300mum. Next, the burial of a P type GaAlAs blocking layer 9 and an N type GaAlAs 10 in the grooves 18 and 19 by a liquid epitaxial method causes partial swelling. Zn is diffused through an SiO2 mask 11, resulting in the formation of a connection layer 12 reaching the P-layer 6. Au electrodes 13 and 14 are attached, which electrode 13 is formed discontinuously at the center of the stripe 21. Thereafter, the wafer 17 is cut at the center of the stripe 21 and split along a cleavage line in the direction perpendicular to the stripe 20, and accordingly a chip 1 is obtained. The chip 1 does not incline because of the swellings at the center and on both sides, thus being improved in thermal diffusion by uniform wetting to a solder 15; therefore the titled element of high reliability and long life time can be obtained.

Abstract: PURPOSE:To enable measurement of a settlement distance of a piping with respect to the axial direction thereof, by a method wherein a laser light is emitted at an observation end of the piping and reflected at a measuring end thereof to perform a computation from a measurement data obtained with a distance measuring device and an angle measuring device. CONSTITUTION:A distance measuring device 12 is set at an observation end of a piping 1 and a laser light 3 is emitted from a laser light emitter 4 aiming at a reflection mirror 2 on the measuring end side. Then, an external driver box 16 is operated observing the position of a gap 14 in an angle measuring device 17 with an external video monitor 5 to adjust a position at which the laser light 3 hits the reflection mirror 2 passing through the gap 14. Then, machine heights lA and lB and an angle theta are measured with devices 12 and 17 and when measurement data thereof are inputted into a data recorder 19, a settlement distance L is computed by a specified formula. This enables observation of the degree of progress in settlement deformation by measuring a settlement distance L when the piping 1 is checked and inspected.

Title: Optical deflector
Inventor: HAMAGUCHI IWAO
IPC: H04N1/113
Filed: 1982-07-08
Abstract: PURPOSE:To reduce a phase shift and to obtain excellent picture quality by setting a magnetic field ripple generated by a motor to an integer multiple of the number of reflecting surfaces of a rotating polygon mirror. CONSTITUTION:A beam emitted from a semiconductor laser 1 is modulated by a recording signal to make a main scan in the axial direction of a photosensitive drum 6 through the rotation of the rotating polygon mirror 4 and also to make a subscan through the rotation of the photosensitive drum 6, forming an electrostatic latent image corresponding to a picture to be formed thereupon. The most important cause of the phase shift of the motor 3 which deteriorates the quality of the picture originates from a magnetic field ripple of the motor 3, so the magnetic field ripple is canceled by being adjusted to an integer multiple of the number of surfaces of the rotating polygon mirror 4. Thus, the phase shift is reduced and deviation due to speed unstableness are both reduced.

Title: Imbalance correcting method for pressure plate and pressure plate
Inventor: KIMURA HIROSHI
IPC: F16D13/71
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To reduce imbalance of a pressure plate by previously providing plural projections, and cutting the projections to correct imbalance. SOLUTION: A pressure plate 12 has plural cylindrical projections 12a for correcting imbalance. In an imbalance correcting method for the pressure plate 12, the imbalance of the pressure plate having projections 12a is measured by using a measuring apparatus such as a balancer or the like. According to the measurement result, the projection 12 in the position corresponding to imbalance is cut by a drill corresponding to the amount of imbalance. Thus, as the projection 12a is independent of the strength of the pressure plate 12, even if the projection 12a is cut, the strength of the pressure plate 12 is not lowered. Further, the correction range of imbalance can be enlarged.

Title: New form strength omega-steel
Inventor: IKETANI SHOZO
IPC: E04C3/04
Filed: 1995-04-07
Abstract: PURPOSE: To improve strength by providing a plurality of omega-shaped ribs on the circumference of a cylindrical shape steel. CONSTITUTION: A rib 2 is made into omega form to improve tensile strength, compression strength and torsional strength. A work having a high field dependency such as reinforcement working is dispensed with to improve the constructing precision in a construction site, and the dispersion in strength is also prevented. Since the sectional area can be minimized, the resource can be saved, and this steel can be used alone for a column or beam. Further, when concrete 4 is used together, compression force is enhanced, and when hoop construction method is used together on the inside because of the circular form, strength and safety are improved. When it is used for a foundation pile, the contact area with the ground is increased to improve the bearing capacity of soil. Thus, a reinforcement or steel work can be dispensed with to reduce the cost, and the strength can be also improved.

IPC: H01L27/115
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To make it possible to improve the polarizing characteristics of a ferroelectric capacitor element, to reduce the leakage current of the element and to improve the dielectric breakdown voltage by forming the structure of a protective film covering the element in two layers, and forming the upper layer film as an Si oxide film with TEOS as a material with ozone used as an oxidizer. SOLUTION: In a capacitor element (ferroelectric capacitor element) using capacitor protective films 10, 11 having a ferroelectric unit 8 sandwiched between electrodes 7 and 9, the films 10, 11 covering in contact with the element are formed in a two-layer structure. The film 10 is formed as a film 10 formed by a sputtering method or a spin-on-glass(SOG) film except a CVD method. An Si oxide film using tetraethyl orthosilicate(TEOS) is formed thereon as the film 11 at the substrate temperature of 350 to 500 deg.C, and then the film 11 is heat treated at a high temperature. Thus, the deterioration of the ferroelectric capacitor film quality due to the reducing reaction is prevented. Further, the increase in the leakage current or the element is suppressed to prevent the decrease in the dielectric withstand voltage.

Title: Air conditioning system
Inventor: KAWAI TAKAMASA
IPC: B60H1/00
Filed: 1998-04-28
Abstract: PROBLEM TO BE SOLVED: To prevent the actual blast quantity from changing even if the detected value of a room temperature detecting means fluctuates by fixing a target wind quantity until the increase/decrease change quantity of a blast quantity variable exceeds a predetermined quantity when the direction of the increase/decrease change of the blast quantity variable is reversed. SOLUTION: A blast characteristic map determines a target wind quantity VM2 in stages based on a blast quantity variable VM1 so that a predetermined hysteresis characteristic can be obtained between a target wind quantity when the blast quantity variable VM1 is changed in the increasing direction and a target wind quantity when the blast quantity variable VM1 is changed in the decreasing direction. When the direction of the increase/decrease change of the blast quantity variable VM1 is reversed, the target wind quantity VM2 at that time is fixed until the increase/decrease change quantity of the blast quantity variable VM1 becomes two stages or above, and the actual blast quantity can be prevented from changing even if the detected value of an internal air temperature sensor fluctuates.  The actual blast quantity can be prevented from changing without reducing the number of change stages of the blast quantity.
