Title: Scroll compressor
Inventor: KARATO HIROSHI
IPC: F04C18/02
Filed: 1995-12-06
Abstract: PROBLEM TO BE SOLVED: To prevent insufficiency of lubricant oil in an oil sump at the bottom of a compressor, by arranging an oil groove to the large shaft part of a crankshaft detachably supported to a main bearing so that lubricant oil in the main bearing is discharged on an electric motor side, and also arranging to the lower part of the baring part, spouting preventing means for discharged lubricant oil. SOLUTION: In a scroll compressor, intake refrigerant gas is discharged from an injection pipe 12 to the outside of a sealed compressor 1 after being taken from an inlet pipe 9 into a compression mechanism part 4 so as to be compressed. In this case, a doughnut disk 101 is arranged as spouting preventing means to the lower part of a bearing part 5 so that lubricant oil 10 in an oil sump 10a can be discharged to the lower space of the disk 101, that is, above an electric motor 7, by being passed through the oil groove of the large shaft 6b of a crankshaft 6 after being pumped up by an oil pump 11 so that bearing parts 5b, 7 and so on have lubricated through an oil hole 6a.  Hereby, the lubricant oil 10 discharged from a main bearing 5b can be prevented from being sucked into the compression mechanism part 4 by being passed through a sealed space, therefore, an appropriate lubricant oil amount can be always supplied to the compression mechanism part 4.

Title: Apparatus for molding resin sealed part of electronic part
Inventor: KANDA KATSUTOSHI
IPC: B29K105/20
Filed: 1991-12-02
Abstract: PURPOSE:To certainly and efficiently find that the wire of the diode mounted on a lower mold has come out of the wire fitting groove of the lower mold. CONSTITUTION:A sensor is provided to a lower mold 42 and brought into contact with an upper mold 41 when both molds 41, 42 are regularly clamped to detect the claming state of the molds. After the parting line surfaces of both molds 41, 42 approach each other up to 1mm, clamping pressure is set to 50kg and the time required before the sensor comes into contact with the upper mold 41 is measured. When this time is 1sec or less, molding operation is continued as it is. When the sensor does not come into contact with the upper mold 41 even after 1sec or more is elapsed, it is judged that a wire has come out of a wire fitting groove to stop molding operation. By this constitution, the leak of a resin to the gap generated between the parting line surfaces can be prevented and the mold can be protected.

IPC: H05B6/12
Filed: 1990-11-22
Abstract: PURPOSE:To reduce generation of noise by making the oscillation frequency of an inverter circuit a value by which no resonance occurs with the inherent oscillation frequency of a pan, and thereby preventing generation of 1/2 resonance being a source for generating noise in an audible range. CONSTITUTION:An invertor circuit 16 is composed to supply a current to a coil 2 by making the oscillation frequency thereof different from a value two times the inherent oscillation frequency of a pan 1. Namely, noises in the audible range caused by 1/2 resonance and strong oscillation as the inherent oscillation of the pan 1 is in conformity with 1/2 oscillation frequency of the coil 2, which hardly occurs, due to the shapes or material qualities of the pan 1 is prevented form generating by making the oscillation frequency of the inverter circuit 16 for supplying a current to the coil 2 have no value two times the inherent oscillations of the pan 1, thereby preventing 1/2 resonance of the pan 1. With this arrangement, no harmful effect of noise caused by generation of 1/2 resonance is given to a user of a cocking unit, which enhances living atmosphere. It is thus possible to reduce generation of noise.

Title: Gas auxiliary injection molding to carpet layer
Inventor: KEISU POORU KUROBUKAA
IPC: B29L31/30
Filed: 1991-11-07
Abstract: PURPOSE: To prevent the tearing or crushing of a carpet layer by injecting a fluid into a molten synthetic resin to forcibly expand the synthetic resin within a mold cavity not only to bond the molten synthetic resin to the surface of the substrate of the carpet layer but also to prevent the same from penetrating into the carpet layer. CONSTITUTION: A carpet material 14 is held between split molds 46, 48 and a thermoplastic material 82 is injected into the mold by an injection spool 84 while nitrogen 80 is injected into the mold by an injection nozzle 86. Nitrogen 80 advances toward both ends of a cavity 88 to be ready to form, for example, an inner runner 16. Nitrogen 80 is stopped within the inner runner 16 and the cavity of the mold is filled with the thermoplastic material 82 by the pressure of nitrogen. Since the thermoplastic material penetrates in a latex liner 74 to entangle the filaments of a carpet layer 14, the carpet layer 14 and a thermoplastic liner 12 are well bonded.

Title: Phosphor screen
Inventor: NAKAOKA YASUYUKI
IPC: H01J29/28
Filed: 1991-12-03
Abstract: PURPOSE:To provide a phosphor screen having an excellent long-term reliability by embedding glass around a phosphor and providing a thin metallic film of high reflectance between is glass and the phosphor. CONSTITUTION:After a glass substrate 1 is coated with a graphite portion (BM) 5, holes for embedding a phosphor 2 are formed in the resulting substrate 1 so as to cause exposure of a glass surface. Then, Ag is precipitated onto the hole side faces through silver mirror treatment to form a thin Ag film 4. Then, a phosphor 2 is filled in each hole. Thereafter, filming is performed using an organic film, after which a thin Al film 6, a total reflection film, is laminated and heat treatment is conducted to form a phosphor screen. This phosphor screen prevents a light of the phosphor from laterally escaping, by the thin Ag film 4 around the phosphor 2, so that the luminance is enhanced. Further, although the reflective film between the phosphor 2 and the glass 3 is made of Ag, the present phosphor screen is not limited thereto but permits use of any metal having a high reflectance.

Abstract: PURPOSE:To reduce the extent of electrode consumption without entailing any excessive temperature rise even if a diameter of nobel metal is reduced, by insetting the columnar nobel metal in a specified hole in a state of being projected, and making a tip part directly contact with a good conductive metal. CONSTITUTION:A columnar complex 401 sealed with a good conductive metal 201 in the inner part of anticorrosion nickel alloy 101, is manufactured by means of plastic working, and the alloy 101 at a tip part of this complex 401 is removed. Then a section circular hole, reaching to the metal 201, ia bored in a tip face of the complex 401. After removing the tip part of a complex 406 bored with this hole, only a part of the alloy 101 is removed so as to a straight part 11 become concentric with the hole. At this time, the columnar noble metal 3 is inset in the hole of the complex 401 so as to make the tip directly contact with the metal 201 in a state of being projected, thus the noble metal 3 is joined to the alloy 101 by means of laser beam welding. If so, the metal 201 makes heat of the noble metal 3 escape, so that even if a diameter of the noble metal 3 is reduced, there is no excessive temperature rise, thus consumption of an electrode is reduced.
