Title: Manufacture of semiconductor device
Inventor: FUSHIDA ATSUO
IPC: H01L21/768
Filed: 1990-11-06
Abstract: PURPOSE:To reduce effective aspect ratio by leaving an Al, film or Al alloy film on the side walls of a contact hole and a viahole, and fusing and fluidizing said Al film or the like to fill the bottom parts of the contact hole and the via hole. CONSTITUTION:In order to obtain more excellent contact between a TiN film 12 and an Al film 13, a new Ti film may be sandwiched between the films 12 and 13. In this case, the TiN film 12 and the new Ti film constitute a first intermediate conducting film. The Al film 13 is etched back so as to leave the TiN film 12 as a barrier conducting film, and an Al film 13a is left only on the side wall of an aperture part 10a. This device is moved in a heat treatment chamber without being in contact with the air, and heat-treated at 500-550 deg.C for 60 seconds, thereby fusing and fluidizing the Al film 13a. As the result, the film thickness is gradual decreased from the side wall to the bottom part of the aperture part 10a. An Al film 13b having a recess type section is buried.

Title: Air-conditioning machine equipped with scroll compressor
Inventor: OKAMOTO JOJI
IPC: F04C18/02
Filed: 1988-11-30
Abstract: PURPOSE:To increase the discharging amount of oil upon high-speed operation by a method wherein a passage to discharge oil in a back pressure chamber is provided and the passage is opened upon the high-speed operation. CONSTITUTION:Oil, supplied from the oil supplying hole 3b of a crankshaft 3 to bearings 8, 4b, flows into a back pressure chamber, in which a pressure is low, and is discharged into a compression chamber through a pressure equalizing hole provided on the mirror plate of a rotating scroll, however, the back pressure chamber is filled with the oil when the supplying amount of oil for the bearings has exceeded a discharging capacity and mixing loss, effected by balance weights, is generated. Further, when oil enters into the notch 4a of a frame, the outer periphery of the rotating scroll compresses the oil and an input is increased. An oil discharging hole 1d, communicating the outer periphery of the mirror plate of the rotating scroll, the low-pressure side of a wrap and the compression chamber, is provided to discharge the oil from the back pressure chamber into the compressure chamber during the rotating operations of both scrolls, however, the discharge of the oil is insufficient when high-speed operation is effected. Therefore, an oil discharging pipe 13, communicated with a frame 4 forming the back pressure chamber and penetrating through a sealed vessel 6, is projected to the outside to discharge the oil, filling the back pressure chamber fully, effectively upon the high-speed operation whereby the mechanical loss may be reduced and the deterioration of performance may be prevented.

Abstract: PURPOSE:To reduce probability of a hole opened at an end seal part by forming seal width of a center part including a back seal part wider than seal width of both sides. CONSTITUTION:A long object made of a package bag material A formed in a cylinder is end-sealed and cut at appropriate upper and lower parts, and a seal part B is formed at the lower part to provide a pillow-type package bag. In the seal part B, seal width of a back seal part (c) is formed wider than seal width of both sides, and the seal part B is formed by sealing an entire center part including the back seal part (a) with a seal bar in a conventional method. The end-sealed part B thus formed at the lower part of the package bag may less probably suffer from a hole opened at the back seal part since seal width of the center part including the back seal part (a) has been formed wider than seal width of both sides.

Abstract: PURPOSE:To utilize the site effectively, and improve the cooling effect by a method wherein the outdoor unit of an air conditioner is stored in an attic, and at the same time, the front surface of the outdoor unit is covered by a louver window. CONSTITUTION:For the title air conditioner, the air outlet of an outdoor unit 2 is arranged to face a ventilation port which is provided in an attic, and at the same time, the front surface of the outdoor unit 2 is covered by a louver window 4. When an exhaust fan 6 of the outdoor unit 2 is operated, air which is drawn from air intake ports 5 being formed on the front surface side and rear surface side is heat-exchanged by a heat-exchanger 7, and is discharged from an air outlet 3. When air is drawn from the air intake port 5 on the rear surface side, the air pressure of the attic reduces, and therefore, the outside air is drawn from the other ventilation port, and the ventilation of the attic is performed. For this reason, a site to install the outdoor unit 2 becomes unnecessary, and the land can be effectively utilized, and at the same time, the appearance of a building is not spoiled. Also, by the forcible ventilation of the attic, warmed air is emitted to the outside, and the temperature of the attic decreases, and therefore, the cooling effect is not spoiled.
