Title: Phase difference measuring system between fm modulation wave and modulation signal
Inventor: NAKAZAWA SOUICHI
IPC: G01R25/00
Filed: 1978-12-13
Abstract: PURPOSE: To ensure the measurement of a high accuracy by fetching the modulation signal and the FM carrier signal out of the composite signal to set the cross over point between the envelope lines of each signal to the zero point and then measuring the mutual phase difference based on the relationship between the zero point and the modulation signal.  
     CONSTITUTION: The composite signal of the FM modulation wave and the modulation signal is supplied to distributor 1, and the output is distributed into three systems A, B and C each. System A is applied to compounder 8 via delay circuit 2 to give the phase change of 180°, and system B is applied to compounder 8 via delay circuit 3, low pass filter 4 and attenuator 5 each to fetch the modulation signal. While system C is applied to compounder 8 via buffer 7, band pass filter 6 and then buffer 7 again to fetch the FM carrier signal. Each signal is compounded through compounder 8, and the crossover point between the envelope lines of each signal is set as th zero point. Thus the mutual phase difference can be measured based on the relationship between the zero point and the modulation signal.

Title: Device for supplying solder wire to soldering spot
Inventor: EGAMI KAZUO
IPC: H01L21/52
Filed: 1998-06-04
Abstract: PROBLEM TO BE SOLVED: To prevent molten solder from adhering to the soldering spots of a lead frame, etc., in excess of a required amount without reducing the diameter of a solder wire which is fed to the soldering spots by appropriate lengths, by forming constrictions on the solder wire at the intervals equal to the appropriate lengths. SOLUTION: A solder wire 5 is fed toward a lead frame 1 by appropriate lengths L by intermittently rotating feed rollers 6 and 7. Then constrictions 10 are formed on the solder wire 5 at the intervals equal to the appropriate lengths L by repeating such operations that the wire 5 is clipped with constriction forming punches 8 and 9 by bringing the punches 8 and 9 nearer to each other in an interlocking way of the intermittent rotations of the rollers 6 and 7. Then the rollers 6 and 7 descend toward the frame 1 while holding the wire 5 between them and bring the front end of the wire 5 into contact with the surface of the island section 3 of the frame 1. Consequently, the front end of the wire 5 is melted by the heat of the frame 5 and adheres to the surface of the island section 3 as molten solder 11.

IPC: H01L21/027
Filed: 1994-07-07
Abstract: PURPOSE:To correct the image deterioration due to the exposure by shifting to a position in the different optical axial direction by a method wherein the sensing raw material having non-linear sensitivity characteristics of the latent image reaction concentration to the incoming light intensity is used for shifting the focal point to the position in the different optical axial direction for expo sure to increase the effective focal point depth. CONSTITUTION:A non-linear sensing raw material has the focal point changing means forming the focal point on the position in the different optical axial direction. A specific pattern on a reticle is projected on a wafer 26 coated with a sensing raw material by a projection optical system 19 so as to shift the reticle in the optical axial direction by the first reticle shifting means 21 after the exposure for the second exposure. After respective exposures, the reticle is further shifted in the optical axial direction by the second reticle shifting means 22 for the du exposures. Through these procedures, the deterioration in the optical image due to the conventional focal shifting method in the different optical axial direction can be compensated, thereby enabling sufficient exposure amount margine to be secured.

Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To prevent lowering of a heat-exchange amount by a method wherein a condensate guide composed of a microgroove in a V-shape in cross section extending from the lower part of a tube to the upper end of a slit cut. SOLUTION: A condensate guide 10 composed of two microgroove in a V- shape in cross section extending from the upper and lower ends of two slit cuts 3, positioned between vertically adjoining tubes 2, to the vicinity of the tubes is formed in a fin plate 1. Condensate gathering on the under surface thereof along the outer peripheral surface of the upper tube 2 is sucked in the groove of the condensate groove 10 and moved to the upper end of the slit cut 3. The condensate flows between the slits 3 and flows to the lower end thereof, and guided from a lower end to the condensate guide 10 again, and moved to the lower tube 2.  Since condensate adhered to the under surface of the tube 2 and suspending is decreased incurring of a pressure loss of an air flow 5 flowing through an air flow passage 6 is reduced, contact with an air flow 5 is effected on the downstream side of the condensate, and heat- exchange performance is improved.

Filed: 1985-07-16
Abstract: PURPOSE:To capture fine particles at high concn. and high temp. continuously and easily by capturing fine particles contained in gas stream at high temp. utilizing adsorbing effect of electrically charged fine liquid particles. CONSTITUTION:In the separation and removal of several kinds of fine particles contained in gas stream at high temp. such as exhaust gas, hot gas contg. fine particles are introduced through a gas introducing pipe 1, and liquid such as water is fed through a hollow cat-whisker 3. Since the liquid in the hollow cat-whisker 3 is heated in the hot gas stream, the viscosity is reduced when the liquid is discharged to the gas stream. Since, moreover, the liquid is ejected to the electric field formed between the hollow cat-whisker 3 and a cylindrical electrode 4, the surface tension is reduced by the electrostatic effect, the liquid is splitted by colliding with a conical surface of the cylindrical electrode 4, promoting thus formation of fine particles.

Abstract: PURPOSE:To eject a cassette surely by operating the holding unit of a cassette transfer means according to the operation of a cassette ejecting means and regulating the operation of the ejecting means by the holding unit until the cassette reaches a prescribed height at an eject time. CONSTITUTION:When an ejecting button is depressed, cam gear 34 is rotated through the decelerating gear interlocked with a motor. BY this rotation, roller 39 brought into contact with inclined cam 35 is depressed to cause cassette arm 44, which is put on roller 40 at the right end of arm 38, and the cassette holder to start ascending to the ejecting position. In this time, depression of depressing part 95 of cassette arm 44 is released in contact part 94 of inject arm 76, and force is given in the cassette contact direction by spring 78, however, cam hole 79 of inject arm 76 is controlled to arc-shaped protrusion 74 of cam gear 34, thereby regulating rotation. When cam gear 34 advances rotation and the cassette ascends to the ejectable highest position, arc-shaped protrusion 74 is desconnected, and injecting arm 76 starts rotating while causing the face of cam hole 79 and the end of protrusion 74 to contact with each other, thus starting cassette ejection.

Abstract: PROBLEM TO BE SOLVED: To prevent the breakaway of a fitting, and allow no deformation of a fall-out preventive fixture by blocking the recessed portion of a luminaire main body with the fall-out preventive fixture, and supporting the luminaire main body with a support step in a state where the installation of the luminaire main body is completed so that no external force is applied to the fall-out preventive fixture. SOLUTION: A fall-out preventive fixture 3 is caused to intervene between a fitting piece 7 interposed in a recessed portion 5 and a luminaire main body 1 so as to block the recessed portion 5 to prevent the breakaway of the fitting. The fall-out preventive fixture 3 is formed of approximately C-shaped sheet material which is cut away with a spacing 23. Thereby, such strength is maintained as the luminaire main body 1 can be supported at a fitting operation time. In a state where the installation of the luminaire main body 1 is completed, the luminaire main body 1 is supported with a support step 8 so that no external force is applied to the fall-out preventive fixture 3 to allow no occurrence of the deformation of the fall-out preventive fixture 3.  Since a cutout is formed in the fall-out preventive fixture 3, the insertion operation thereof between the luminaire main body 1 and the fitting piece 7 becomes easy, and since the cutout spacing 23 is formed, the mutual overlapping of cutout end faces is prevented.
