Title: Welding method for preventing weld crack by electron beam
Inventor: MIYAZAWA TAKASHI
IPC: B23K15/00
Filed: 1981-02-02
Abstract: PURPOSE:To prevent the longitudinal crack of a down slope part through lowering of cooling rate by controlling beam current gently at the start of the down slope and further agitating molten pool by beam deflection. CONSTITUTION:In the stage of shifting from a section 7 of steady penetration in electron beam to a down slope, beam current Ib is controlled to a gentle slope to prevent the generation of an imperfect solidification mode in a part 8. Further, just prior to the shift to the down slope, the molten pool is agitated by rotating the electron beam in a circular shape C or oscillating (d) the same in the welding direction, whereby the segregation of a metallic compound on account of an increased rate of cooling is suppressed and the longitudinal crack of a welded part W is prevented.

Title: Refrigerator
Inventor: KATAGAI KIYOSHI
IPC: F25D19/04
Filed: 1988-01-25
Abstract: PURPOSE:To improve evaporating capacity in an evaporating dish for defrosting water without damaging the capacity of a refrigerant circuit by mounting a first refrigerant circuit which includes a cooler for cooling the refrigeration room and a second refrigerant circuit which includes a cooler for a cold room and filling a refrigerant of boiling point in the first circuit. CONSTITUTION:Since a refrigerant R502 is filled in a first refrigerant circuit 72 and the temperature of a cooler 18 for a refrigeration room can be -40 deg.C or lower, first and second refrigeration rooms 14, 15 can be cooled up to very cold temperature lower than -30 deg.C. The temperature of the refrigerant discharged from a first compressor 62 is very high and the other temperature of a condenser 64 for a first evaporating dish is higher than that of another condenser 65 for a second evaporating dish. Defrosting water from the cooler 18 for a refrigeration room and the other cooler 44 for a cold room is introduced in an evaporating dish 66 and heated and evaporated by the condenser 64 for the first evaporating dish. Since the condenser 65 for the second evaporating dish is placed lower than the condenser 64 for the first evaporating dish, heating is prevented, the condensers 64, 65 for both the evaporating dishes are radiated efficiently and the cooling capacities of the refrigerant circuits 72, 80 can be maintained efficiently.

Title: Fabric presser elevating and lowering device
Inventor: OGAWA MASAO
IPC: D05B29/02
Filed: 1998-01-27
Abstract: PROBLEM TO BE SOLVED: To reduce the operating load of a knee lever by simple constitution. SOLUTION: When a knee lifter lifting lever 27 is operated in the direction of an arrow A, a presser bar guide bracket 26 is pressed up by the lever 27 to elevate a presser bar 23. When the lever 27 is engaged with the bracket 26 after this, the bracket 26 is supported by the lever 27 to hold the bar 23 at an elevated position. When a knee lever 26 is operated in the direction of an arrow D, a lifter 50 pushes up the bracket 26 to release the engaging between the bracket 26 and the lever 27. Thereby, cam operation and lever operation by the lifter 50 are operated at the elevated position of the bar 23 to reduce the operation force of the lever 36.

IPC: H01L33/00
Filed: 1994-01-12
Abstract: PURPOSE:To allow growth of a buried layer by removing the part, having no protective film, on a III-V compound semiconductor film containing InP, In and As by etching using a gas obtained by thermally decomposing arsenic chloride, and regrowing a compound semiconductor crystal at the removed part thereby forming a mesa of desired profile without causing any thermal damage on the crystal. CONSTITUTION:A double hetero epitaxial crystal is grown on an InP substrate having an active layer of InGaAsP followed by deposition of SiN which is then patterned into stripe by lithography. The wafer having the stripe protective film is then subjected to mesa etching with bromate and placed in an epitaxial furnace which is eventually evacuated and the temperature thereof is raised before second mesa etching is performed using a gas produced by thermally decomposing arsenic trichloride. The wafer is transferred into a second growth chamber immediately after mesa etching and the growth of burying layer is started. The PNP burying of InP crystal is performed independently in different growth chambers.

Title: Storing method for trace information of transmission line
Inventor: HAMADA TAKUSHI
IPC: H04L69/40
Filed: 1980-02-08
Abstract: PURPOSE:To make it possible to detect the fault positions of a transmission line by resetting FF with a signal from an event generation informing line or resetting FF with a signal outputted when a time counting circuit has completed a fixed time counting. CONSTITUTION:A signal indicating frame receiving which is supplied from transmission control circuit 6 through frame receiving information line 62 resets time  counting 201 through or gate 202. A circuit error information input completing signal supplied from trace control circuit 12 through input information line 63 sets  FF203 and, at the same time, starts time counting circuit 205 to start counting for a prescribed time. The output of FF203 keepts circuit 201 reset status through or gate 202. Time counting is continued until a signal from event generation informing circuit 61 resets FF203 through or gate 204 or a signal outputted when circuit 205 has completed a fixed counting resets FF203. Thus, fault positions of the transmission line can be easily detected.

Title: Optical-quantity measuring circuit
Inventor: TANAKA MAKOTO
IPC: G01J1/46
Filed: 1989-01-25
Abstract: PURPOSE:To obtain the result of the measurement of the quantity of light in an accurate digital value all the time by taking out the stored value in a latch circuit as the measured value of the quantity of the light which is received with a light sensor in measuring circuit using a charge storage type optical sensor. CONSTITUTION:A counted value is changed in response to the rise-up of a counting pulse CP in a counter 40. At this time, a synchronizing circuit 20 makes a latch circuit 30 read the counted value after the end of the counting operation of the counter 40 in synchronization with the fall-down of the counting pulse CP in the reverse direction. Thus, the storing of the erroneously counted value during the counting operation can be prevented. For example, ON/OFF operations in transmission gages 21 and 22 based on the counting pulses CP in the synchronizing circuit 20 are reversed, and an inverter 23 and a NAND gate 24 can be switched. At this time, an output S from a light sensor 10 is imparted to said deformed synchronizing circuit. Reading is instructed to the latch circuit 30 at a logic value L based on the synchronous output SS. When the deformed synchronizing circuit formed in this manner is connected to the regular synchronizing circuit, the reading of the erroneously counted value in the latch can be positively prevented.

Title: Ic card module
Inventor: GOCHI HIDENOBU
IPC: G06K19/077
Filed: 1988-01-26
Abstract: PURPOSE:To enhance humidity resistance without damaging the strength of a module, by bringing the potting resin of a semiconductor chip to a multilayer structure using a resin containing a filler and a resin containing no filler. CONSTITUTION:In the case of a two-layer structure as a module for an IC card, since the surface of said module is covered with a resin 6 containing a filler 8, the penetration of moisture through the interface of the filler in the surface layer and the resin is prevented even when said surface is mechanically polished. Even if moisture is penetrated in the second layer 6 from a pinhole, there is no gap in the interface of the filler 8 and the resin 5, because the first layer 5 is not polished and the penetration of moisture can be prevented by the interface of the first and second layers 1, 2. Since a semiconductor chip 2 and an Al wire 4 are covered with the potting resin 5 containing the filler 8, heat conductivity and strength are not deteriorated. A multilayer structure may be formed by further inserting a humidity-resistant layer or hard layer between to layers.
