Title: Semiconductor laser element and fabrication thereof
Inventor: TSUNEKANE MASAKI
IPC: G02B6/122
Filed: 1992-08-26
Abstract: PURPOSE:To permit efficient capturing of oscillation light by providing a current block layer closely to an optical guide layer in a window region, making the current block layer transparent for the oscillation light, thereby minimizing leakage current entering into the window region. CONSTITUTION:Oscillation light from a quantum well active layer 3 is guided in a p-buried guide layer 5 provided closely to a resonator surface 40 in a window region and then emitted from the right and left resonators 40. Since the p-buried guide layer 5 is transparent for the oscillation light and the oscillation light is not absorbed by the resonator surface 40, thermal fracture does not take place and stabilized operation is ensured upto high output. Furthermore, an n-current block layer 7 having different conductivity type is provided closely on the optical guide layer 5 in the window region in order to suppress leakage current entering into the window region effectively. The n-current block layer 7 does not absorb the oscillation light and thereby does not deteriorate the oscillation characteristics of laser element.

Title: Slurry coating jig
Inventor: OGUMA MIKIO
IPC: B05C3/12
Filed: 1984-11-28
Abstract: PURPOSE:To eliminate the adhesion of a a slurry to the blank part of a core material, by providing a projection to the leading end of the roll of a slurry coating jig and positioning the upper end of the surface, which is contacted with a core material, of the roll above the lower surface of a slit. CONSTITUTION:In the coating of a slurry in the manufacturing of a battery electrode plate, a core material 1 is passed through the vat filled with the slurry and drawn up through a slit 8. At this time, from the part contacted with the blank part of the core material, the slurry is scraped by opposed rolls 12 arranged so as to be mutually pressed to the lower surface of the slit 8 by a spring 9. Therefore, even if the slurry penetrated between the lower surface of the slit 8 and the upper surface of the roll 12 is gradually pushed out to the leading end side of the roll 12 during coating work, said slurry is blocked by the projection 16 provided to the leading end of each roll 12 an does not reach the surface of the core material. As a result, the slurry is prevented from again adhering to the blank part.

Title: Exhaust gas purifying structure
Inventor: KUSUDA TAKAO
IPC: F01N3/02
Filed: 1987-10-05
Abstract: PURPOSE:To prevent occurrence of crack by applying compressing force between ring stoppers and holding the opposite ends of a honeycomb structure. CONSTITUTION:Opposite ends of a honeycomb structure 1 to be utilized as a catalyst converter or a filter of an internal combustion engine are held by ring stoppers 6a, 6b. A spring 10 is arranged between inner and outer containers 4a, 4b, then compressing force is applied between the stoppers 6a, 6b. Since the outer circumference of the honeycomb structure is compressed axially to cancel tensile force subjected to the outer circumferential section, occurrence of crack can be prevented.

Title: Apparatus for controlling defrosting of dehumidifier
Inventor: MORI YUUJI
IPC: B01D53/26
Filed: 1983-12-29
Abstract: PURPOSE:To contrive to decrease electrical inputs and to increase dehumidifying capacity without rendering the heat inertia of an electric heater for defrosting wasteful by turning off the electric conduction of said heater due to a defrosting finish signal and thereafter operating a compressor and a fan motor after the lapse of a set time. CONSTITUTION:In a dehumidifier provided with a refrigerating cycle consisting of a compressor 1, a condenser 2, a decompression device 3 and an evaporator 4, when the evaporator 4 is frosted, a sensor 7 for defrosting signal sends a start signal for defrosting at X point of time, and sends a finish signal for defrosting at a Y point of time. At the Y point of time, an electric heater 6 for defrosting is stopped only and the compressor 1 and a fan 5 are not actuated at the period Y-Z preset by a timer and the defrosting is continued by the heat inertia of the electric heater 6 and finished till a Z point of time. Since the electrical input is not used at the period Y-Z, energy consumption is economized and the defrosting can be started immediately because the temp. of fins of the evaporator 4 is lower in comparison with a conventional method.

Title: Surface treated steel sheet for lead frame having superior corrosion resistance, solderability and adhesion
Inventor: HIGUCHI YUKINOBU
IPC: C25D5/26
Filed: 1986-10-22
Abstract: PURPOSE:To obtain stock for a lead frame having especially superior corrosion resistance, solderability and adhesion by forming a Cu coating layer of a prescribed thickness on a Cr-contg. steel sheet contg. specified amounts of C, acid- sol. Al and Cr. CONSTITUTION:The above-mentioned stock is obtd. by forming a Cu coating layer of 1.5-10mum thickness on a Cr-contg. steel sheet consisting of, by weight, <=0.30% C, 0.005-0.10% acid-sol. Al, 3-11% Cr and the balance Fe with inevitable impurities. One or more among 0.05-1% Cu, 0.05-3% Ni and 0.05-0.5% Mo may be incorporated into the steel sheet so as to improve the rust preventiveness and corrosion resistance. Those elements give higher potential in combination with Cr in a corrosive environment and reduce the potential difference between the steel sheet and the Cr coating layer, so the deterioration of the rust and corrosion resistances by the preferential corrosion of Fe can be further prevented.

Title: Apparatus for plasma treatment
Inventor: SAKAZUME SHUNSUKE
IPC: H01L21/3065
Filed: 1986-10-22
Abstract: PURPOSE:To realize the manufacture of a semiconductor device at a good yield rate by an apparatus wherein a process chamber is separated from a plasma-generating chamber and the plasma-generating chamber is connected to the process chamber via a plasma-intake pipe. CONSTITUTION:After a wafer 13 has been fixed on a stage 12 and the inside of a process chamber 10 has been evacuated through a vacuum exhaust hole 11 to obtain a prescribed degree of vacuum, a gas for processing use is introduced into a plasma-generating chamber 14 through an intake 15. If an AC voltage is applied to a solenoid 16, a plasma is generated inside the plasma- generating chamber 14. At this moment, a ring-shaped magnetic field is generated with the solenoid 16 inside the plasma-generating chamber 14. Because charged particles inside the plasma move in a cycloid form along the line of magnetic force at the magnetic field, they hardly go out from the magnetic field and hardly give a shock to the wafer. In addition, because a neutral radical is introduced through an obliquely-shaped plasma-introduction plate 18 into the process chamber 10 and produces an effect on the wafer 13, the radical can reach the central part of the wafer sufficiently. It is possible, therefore, to process the wafer 13 uniformly.
