Title: Positioning accuracy compensation method in printed circuit board finishing machine
Inventor: NAGASAWA KATSUHIRO
IPC: B23Q15/22
Filed: 1991-12-18
Abstract: PURPOSE:To make yet higher accurate positioning and machining achievable by compensating any possible error due to accuracy from the manufacturing standpoint of a PCB machine itself. CONSTITUTION:In the case where a traveling route of a table 3 is tilted or moved in zigzag to an X-axis of a printed circuit board finishing machine, this table 3 comes to be displaced in the Y-axial direction in consequence. An amount of Y-axial displacement in an optional position in the X-axial direction of the table 3 is then measured, and on the basis of the measured result, travel of a cross slide 6 is compensated, whereby yet more accurate position takes place. Likewise, as for displacement of the cross slide 6, the travel of the table 3 is compensated. In addition, since inclination of the traveling route of a saddle 9 to the Z-axis comes out as the X-axial displacement, each travel of the table 3 and the closs slide 6 is compensated, thus accurate position is performed.

Abstract: PURPOSE:To melt a metal in a high-purity state without contaminating the metal at the time of melting the metal in a crucible made of a water-cooled copper strip-shaped segments by induction heating by fixing a calcia-based refractory to the crucible bottom face and forming a thin skull on the bottom face in the course of melting. CONSTITUTION:Many strip-shaped segments (a) consisting of a watercooled copper pipe are assembled, and an active metal such as Ti and Zr, their alloy, a high-melting-point metal such as Cr, etc., are melted by an induction power in a crucible enclosed by an induction heating coil (b). In this case, a calcia- based refractory (c) is fixed only to the bottom face, and the melting condition is adjusted to form the solidified crust (skull) of the molten metal in 2-40mm thickness. The calcia layer (c) contains >95% CaO, <6% CaF and <2% of an oxide such as SiO2, and the density after sintering is controlled to 40-90% of the true density and the thickness to 5-60mm. Consequently, impurities such as oxygen are not infiltrated unto the molten metal (d), and the uncontaminated molten metal is obtained.

Abstract: PROBLEM TO BE SOLVED: To quickly connect a metal tube and a joint, such as a flange, at low costs and to obtain a strong fixing force by forming a projecting part engaged with a groove from the inner surface of the metal tube in a portion of the outer periphery of the metal tube. SOLUTION: A joint 2 is composed of a screw part 3 and a nut part 4 and provided with a cylindrical tube connecting hole 5 slightly larger than the outer diameter of a metal tube 1 and a U-shaped groove 7 is provided in its small diameter hole 6a in an axial direction. The joined structure of the metal tube 1 and the joint 2 is constructed in such a manner that the large diameter part 1a of the metal tube 1 is locked in the large diameter hole 6b of the tube connecting hole 5 and a reverse U-shaped projecting part 8 formed in a part of the outer periphery of the metal tube 1 is deeply engaged with the groove 7 from the inner surface 9 of the metal tube 1. Thus, since the projecting part of the metal tube is deeply engaged with the groove of the tube connecting hole of the joint by tube expansion or pressing in, the relative rotations of the metal tube and the joint are prevented and strongly fixed.

Title: Refrigerator equipped with automatic ice making machine
Inventor: SUMIHIRO KATSUSHI
IPC: F25C1/24
Filed: 1990-11-30
Abstract: PURPOSE:To indicate the replacing timing of water in a feed water tank optimally and prevent malfunction in indication due to noise and the like at the same time by a method wherein the existence of water supplied into an ice making pan is decided based on a detecting temperature detected by a temperature sensor while counting operation is started by a control signal outputted when it is decided that the water exists and a feed water tank is set. CONSTITUTION:A control circuit 8 receives the supply of a detecting temperature signal from a temperature sensor 12 and decides the existence of water fed into an ice making pan. In this case, when a feed water tank is set, a feed water tank switch 6a is closed and the input of the control circuit 8, on which a positive voltage is impressed from a terminal 82 through a resistor 81 until that time, becomes a grounded potential and, therefore, an output of the control circuit 8 resets a timer 9. Count lock enters automatically in the reset timer 9 and the timer counts a predetermined time necessitating the replacement of water. The potential of a count-up output at a time point when the counting is finished becomes a high potential and conducts current for a switching transistor 9 through a base resistor 10a whereby an indicator 7 consisting of a LED is driven and a lamp is lighted.

Title: Semiconductor laser and its manufacture
Inventor: SUZUKI TAKAFUMI
IPC: H01S5/12
Filed: 1996-12-17
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor laser whose wavelength uniformity can be enhanced by a method wherein an active layer and a light guide layer are formed by a selective growth method. SOLUTION: An active layer 13 which induces and dicharges a laser beam and a light guide layer 14 which distributes and feeds back the laser beam by a diffraction grating 20 are formed continuously by a selective growth method. When a mesa structure by the respective layers 13, 14 is formed by the selective growth method, the mesa width of the respective layers 13, 14 is changed so as to correspond to the opening width of a mask as a region width by the selective growth method. At this time, the mesa structure is formed by the selective growth method by making use of a 111B plane as a side face, its growth progresses, a layer width is narrowed, and the growth speed of a layer thickness becomes fast.  When a change in the layer width and a change in the layer thickness are opposite, a change in an equivalent refractive index due to the change in the layer width and a change in an equivalent refractive index due to the change in the layer thickness are compensated alternately, and the equivalent refractive indexes can be made nearly definite. As a result, a semiconductor laser can be manufactured to a desired oscillation wavelength, a production error is compensated, and it is possible to manufacture the semiconductor laser whose oscillation wavelength is uniform.

Title: Photosensor
Inventor: KANDA MASAHIKO
IPC: A61B5/0245
Filed: 1990-11-29
Abstract: PURPOSE:To achieve a higher measuring accuracy with a better light shielding state as photosensor by arranging a photosensor to detect a quantity of light received with the other light emitting element when light is emitted from any one of a plurality of light emitting elements to control an amount of emission of the light emitting elements. CONSTITUTION:A light emitting element 13 has LED chips LED1 and LED2 and a CPU1 is provided in a processor for measuring a pulse and a blood pressure value to control an amount of emission of the light emitting element 13. When any one of the LED chips LED1 and LED2 emits light, the other element detects the quantity of light thereof. Reception outputs of the chips are applied to amplifiers 4 and 5 through switches 33 and 34 of an analog switch 3 to amplify and converted into digital signals with an A/D converter 6 to be applied to the CPU1. The switches 31-34 of the analog switch 3 are changed over by a control signal from the CPU1. This enables the canceling of a drift of the amount of emission because of temperature changes in the LED chips LED1 and LED2 thereby eliminating the need for photo diodes.
