Title: Method for soldering ic chip
Inventor: KAMIYANAGI KATSUMICHI
IPC: B23K26/21
Filed: 1989-01-26
Abstract: PURPOSE:To prevent the failure of a circuit wiring part by forming a metallic film which relieves the temp. gradient in the circuit wiring part by irradiation of laser light on the rear side of an IC chip. CONSTITUTION:The metallic film 10 which consists of Cr or the the like and has an adequate reflectivity to the laser light is previously formed by vapor deposition or sputtering on the rear surface of the IC chip 3. Nearly 60% of the laser light is absorbed by this metallic film if the IC chip 3 is positioned on a substrate 2 and is then irradiated with the laser light 8. The remaining laser light is converted to heat to increase the temp. at the relatively mild gradient in the thickness direction from the rear surface of the chip to the circuit wiring part 9 on the front. Solder bumps 7 are melted at a uniform temp. without generating the sharp temp. difference at the boundary between the IC chip and the circuit wiring part 9. The electrode patterns 6 on the substrate are thus soldered.

Title: Method and device for measuring inner profile of lining of refractories
Inventor: ASANO YUUICHIROU
IPC: G01B11/24
Filed: 1983-02-08
Abstract: PURPOSE:To make it possible to measure the inner profile of the lining of refractories accurately and to make the repairing work of the damage on the inner surface accurate, by applying accurate estimation from time to time during the measurement with respect to the curved shape of the central axis of a measuring lance, and correcting the measured result based on the above described application. CONSTITUTION:In general, the central axis of a hollow lance 3 is not a stright line as shown by l, but a curve such as l' due to gravidy and vibration, and is changed with time. Therefore measuring errors occur in the information with regard to the position of measuring point and the thickness of the wall of a furnace. In order to correct the error, a laser beam 14 is inputted into the hollow lance 3 usually separately, in the specified direction from the backward of a lance supporting part 4. A distance DELTAy from a reference point A on a detector to a light point B is detected by an optical position detector 15, which is provided in front of the lance. When DELTAy is imparted, the function form of the curve l' is determined. Therefore the geometrical conditions of a laser light projecting part 10 (x=x1) and light receiving part 11 (x=x2) are determined. By this method, the correct position of a laser spot 12b can be detected, and the accurate shape of an inner wall surface 2 of a furnace can be measured.

Title: Pump
Inventor: HIRUMA KOJI
IPC: F04B9/04
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To smoothly change a motion into a linear motion, to reduce vibration and to suppress generation of pulsation by providing a pump with a cylindrical cam which is formed in a free contour shape in a circumferential direction of a cylinder surface and has a groove in which a drive pin engaged with a connection rod is fitted. SOLUTION: Since a groove of a cylindrical cam 5 is formed in a sine curve shape, a piston 4 is vertically operated when the cylindrical cam 5 is rotated by a motor. With a balance of a torque of the motor and the length of a piston cylinder, the amplitude of the sine curve of the groove, its total length and a cycle can be properly designed. However, since a continuous groove without a final point is to be formed, the groove must be integral multiples of the since curve. In order to arrange a pump wherein an excessive load is not applied to the motor and vibration is reduced, the most preferable sine curve is such that the diameter of the cylindrical cam is nearly equal to the amplitude of the since curve, and that one rotation of the cylindrical cam 1 forms one cycle.

Title: Image pickup method for scanning type microscope
Inventor: HAKAMATA KAZUO
IPC: G02B21/00
Filed: 1990-01-29
Abstract: PURPOSE:To shorten the time necessary for image pickup by picking up an image in a main scanning fly-back time in addition to an ordinary main scanning time when an optical system and a sample dish are relatively moved so that main scanning and sub scanning by the light spot of illuminating light may be performed on a sample. CONSTITUTION:A continuous line T expresses a scanning locus in a period when an image signal S is fetched, and a broken line T' expresses a main scanning fly-back line. When the image signal S is fetched, digital image data Sd becomes one showing that image information on a line turns right and turns left alternately as for each data on one scanning line. Furthermore, the image signal S is fetched even in the sub scanning fly-back time, so that the image data Sd is arranged in order of the scanning lines 1, 2, 3... concerning a certain image but it is arranged in order of the scanning lines 525, 524, 523... concerning the image picked up next. Even though the digital image data Sd is arranged in such order, the image data Sd is inputted in an image reproducing device as it is so as to correct and reproduce the microscopic image of the sample when scanning display or recording system in the image reproducing device corresponds to such order of arrangement.

Title: Diagnostic device for image recording thermal fixing device and image recorder
Inventor: KIMIZUKA JUNICHI
IPC: G03G15/20
Filed: 1994-02-15
Abstract: PURPOSE:To diagnose the presence of a defect of a resistance type temp. senser such as a thermistor, etc., detecting a temp. of a thermal fixing device and to prevent abnormal heat generation in the thermal fixing device by impressing a voltage to the resistance type temp. senser, generating self heat generation and comparing detected resistances before/after the voltage is impressed to the temp. senser. CONSTITUTION:A voltage impressing means is constituted of a circuit impressing the voltage to make the thermistor 1 generate the self heat generation. When the thermistor 1 is self heat generated, the voltage exceeding the breakdown strength of an A/D converter port of a CPU 3 occurs on both ends of the thermmstor 1. Then for preventing the port from destroying, a resistor 12 and a diode 14 are used. Then, the resistance type temp. senser such as the thermistor 1, etc., provided in the thermal fixing device is self heat generated, and from the change in resistance values before/after the self heat generation, the resistance type temp. senser such as the thermistor 1, etc., is diagnosed. Thus, the presence of the defect of the resistance type temp. senser is judged in a remarkably short time without heat generating the thermal fixing device.

Title: Timing feeding system
Inventor: KAWASHIMA SEIICHI
IPC: H03K5/15
Filed: 1982-02-08
Abstract: PURPOSE:To obtain a system having almost no timing skew with simple constitution, by using a timing signal obtained by mixing the timing signal of plural phases of timings and a signal selecting pulses from the timing signal. CONSTITUTION:Signals 101, 201 and 301 are mixed timing signals including two-phase timings, and signals 102, 202, 302 and 303 are selection signals for picking up basic signals of each phase from the mixed timing signals. The signal 301 reaching an IC31 produces a skew with the timing signals at an input terminal of the IC in other logical package due to the dispersion at transmission from a timing generating source 1 to the input terminal of the IC31, but since the relation of the phase between the two timings is constant in the signal 301, no timing skew is produced in the IC31. Thus, the permissible maximum transmission time between the two timings is increased.
