IPC: H01P1/04
Filed: 1991-02-04
Abstract: PURPOSE:To realize the mount structure eliminating a gap of an input/output transmission line connection part of a function circuit module with respect to the mount structure of the microwave and millimeter integrated circuit. CONSTITUTION:Slits 11,12 are provided alternately from the front side and the rear side of a stage part 5 mounting a metallic carrier or a metallic package to a case so as to allow the stage part to be expanded/contracted to depress the said metallic carrier or metallic package from both sides.

Title: Ventilating fan for gas range
Inventor: TAKASHIMA KATSUO
IPC: F24F7/013
Filed: 1985-02-25
Abstract: PURPOSE:To make noise form a ventilating fan low, by preventing current wave forms from pulsating when the number of revolution of a capacitor induction motor is changed, by providing a plurality of capacitors of which capacitances are different from each other on the side of a power source, and by selecting one of the capacitors by selectively changing the capacitors. CONSTITUTION:A plurality of capacitors 6 and 7 of which capacitances are different from each other are provided in parallel between a capacitor induction motor 1, which drives a ventilating fan for gas range, and an electric power source 5. The capacitors 6 and 7 can selectively be selected and be contacted to the therminals 9 and 10 of a changing switch 8. When the changing switch 8 is thrown into the terminal 9 or 10 to drive the motor at medium speed or at low speed, sinusoidal waves are formed in any case as well as is the case that the switch is thrown into the terminal 13. As a result low noise and stabilized operational characteristics can be obtained in the capacitor induction motor 1.

Title: Connection structure of ic chip and its method
Inventor: YAMAMOTO MICHIHIKO
IPC: H01L21/60
Filed: 1992-01-28
Abstract: PURPOSE:To prevent generation of short-circuit between adjacent solder bumps, when the pitch of IC chip electrodes is fine. CONSTITUTION:An IC chip 21 is provided with a solder layer 29 of low melting point under an electrode 23. A wiring board 31 is provided with a solder bump 36 of high melting point on a connection pad 33. Said bump 36 is composed of a barrel type solder part 36a and a circular cone type solder part 36b. When themocompression bonding is performed at a heating temperature wherein the solder layer 29 is fused but the solder bump 36 is not fused, the barrel type solder part 36a is not crushed in the lateral direction but the cone type solder part 36b is suitably crushed via the solder layer 29 by a metal bump 28. Thereby the solder bump 36 is not stretched in the lateral direction as a whole, so that short-circuit between the adjacent solder bumps 36 can be prevented when the pitch of the electrodes 23 is as fine as 100-150mum.

Title: Ultrasonic wave microscope
Inventor: KANDA HIROSHI
IPC: G01H3/12
Filed: 1983-03-07
Abstract: PURPOSE:To obtain a signal equivalent to a transmitted signal from a transmitting structure from a reflecting structure, by providing a specified constitution for a sample table supporting a sample. CONSTITUTION:The upper surface of a sample of a living thing 5 having a certain thickness is l1 and the lower surface thereof is l2. An acoustic reflecting body 6 is lined on the lower surface l2. An ultrasonic wave is inputted into the sample 5 in water 8 from a probing system 10 from the upper part over the sample 5. A part of the ultrasonic wave is reflected by the interface l1. The most of the wave is propagated in the sample 5. The wave, which is propagated in the sample 5, is reflected by the interface l2 and outputted into the water 8 through the sample 5 and the interface l1. The wave is detected by the probe 140 as the reflected wave. The reflection at the interface l2 is almost perfect, and the reflected signal, which is very larger than the reflected signal from the interface l1, is obtained. Since the signal from l2 passes the sample and is outputted, the signal equivalent to transmitted signal is obtained.

IPC: B22D11/04
Filed: 1987-02-19
Abstract: PURPOSE:To obtain good shrunk section of molten metal and to enable continuous drawing by arranging circumferential coils at near boundary of a tundish nozzle and a mold as eccentrically toward upside and changing an AC current-time changing ratio, as less at increasing the current and as larger at decreasing the current. CONSTITUTION:An electromagnetic field generating means 18, consisting of the first coil 34 and the second coil 35 at near boundary of the nozzle 14 of the tundish 1 and the mold 3, as surrounding the boundary, is arranged. Axial center of the coil 35 is dislocated as eccentrically toward upside, to make constricting force toward upside to molten metal flow larger and to obtain good shrunk section by gravity compensation. Further, the time-changing ratio for AC exciting current generated in the coil 18 makes less at increasing the current 61 and larger at decreasing the current 62, to turn constantly the constricting force toward centripetal. Sticking of a solidified shell to the mold 3 is prevented by flowing of lubricating oil 46 through the cercumferential nozzle 42 at near the shrinking starting point 44 of the molten metal flow, to execute smoothly horizontal continuous casting drawing. The above- mentioned electromagnetic generating means 18 may generate large current at underside coil by arranging plural bar-type coils toward axial direction.

IPC: F24S90/00
Filed: 1984-02-28
Abstract: PURPOSE:To solve the shortage of heat collecting amount in winter and effect efficient heat collecting operation by a method wherein a temperature detector, detecting refrigerant temperature and switching a four-way valve into a refrigerant reverse circuit, is provided and first bypass pipe is provided in parallel to a pressure reducer while the second bypass pipe is provided from the intermediate piping of the heat collector to the outlet pipeline thereof. CONSTITUTION:In case an atmospheric temperature is low in winter, the evaporating temperature of refrigerant in the heat collector 5 is reduced and frosting is caused on the surface of the heat collector 5. In this case, the refrigerant temperature is detected by the temperature detector 8 to switch the four-way valve 2 into a defrosting circuit and flow the overheated compression gas of a compressor 1 to the outlet of the heat collector 5 and the intermediate area of the same collector 5, whereat heavy frosting is readily caused, through the second bypass pipe 9. The frost is molten and the refrigerant is condensed and liquefied by the condensing heat and the refrigerant flows into the condenser 3 through the first bypass pipe 7 and is heated by water, sent from a pump 12, through the heater 13, thereafter, is returned to the compressor 1 through the four-way valve 2 after being evaporated and gassified. When the defrosting of the heat collector 5 is finished, the refrigerant temperature at the inlet port thereof is increased and the temperature detector 8 detects it to switch the four-way valve into a heat collecting operation circuit. Accordingly, the heat collecting operation may be effected even in such low atmospheric temperature that causes frosting by only effecting the defrosting operation for a short period of time.
