Abstract: PURPOSE:To prevent lubricating oil from overflowing or becoming short in a pump by providing a pair of oil separators in mid course of a compressed air feeding line in series and sucking and returning oil separated in downstream oil separator by an oil pump rotated integrally with a gas pump. CONSTITUTION:In a vane pump 1 as a gas pump, when a rotor 7 is rotated, air is sucked from a vacuum tank 8 to a pump chamber P through a suction port 11, and then compressed by contraction of the pump chamber P and fed to a compressed air feeding line 2 through a discharge port 12. In this case, two oil separators 31 and 33 are provided in mid course of the compressed air feeding line 2 in series, and an oil conducting line 33 for the oil separator 31 on the upstream side is connected to a top wall of a closed oil tank 5. On the other hand, an oil conducting line 34 for a downstream oil separator 32 is connected to a suction port 41 of an oil pump 4. Then a discharge port 42 of the oil pump 4 is connected to a side wall of the tank 5 through an oil discharge line 54. Thus oil separated in the downstream oil separator 32 is sucked forcibly to the oil pump 4 and collected to the tank 5.

Title: Solid electrolytic capacitor
Inventor: KADO YUTAKA
IPC: H01G13/00
Filed: 1989-12-26
Abstract: PURPOSE:To ensure the welding strength of a lead terminal by fastening an electrode foil in the folded portion of the lead terminal before welding. CONSTITUTION:An aluminum-based foil having a coarse surface is anodized to form a dielectric film. The foil with the dielectric film, as an electrode, is grasped in a folded portion 3 of a lead terminal 2. The folded portion is welded both sides to form an electrode l. The dielectric film of the electrode 1 is coated with conductive polymer film such as pyrrole, thiophene, aniline, or furan. This permits welding current to flow to the joint uniformly. Since the joint is under pressure, the welding proceeds while sponge-like stuff or the dielectric film on the electrode is removed. Therefore, a double-sided strong weld is obtained.

IPC: H04N1/113
Filed: 1992-12-22
Abstract: PURPOSE:To speedily form images and to form images with high picture quality by emitting laser beams before the speed of a scanning means reaches image formation enable speed. CONSTITUTION:The revolving speed of a polygon 3 on standby is lowered rather than the speed during a copy operation. Therefore, when the copy operation is started, the operation to accelerate the revolving speed of the polygon 3 is started, and when the polygon 3 reaches the copy enable revolving speed, image formation is performed. In this case, before the polygon 3 reaches the high-speed revolution, the laser beams are emitted by using a means for detecting the revolving speed of the polygon 3 and a means for changing BD timing from the data. The beam emitted from a semiconductor laser 1 is turned to almost parallel light by a collimator lens 5 and an iris 2 and made incident to the polygon 3 with a prescribed beam diameter. The polygon 3 is revolved in the direction of an arrow at equal angular velocity.

IPC: H01L23/50
Filed: 1989-12-28
Abstract: PURPOSE:To secure adhesion of respective leads by making at least a surface of each lead of a copper material and forming a blackened reduced coating on a face in contact with at least mold resin of the copper material and a base. CONSTITUTION:In a board 10 for mounting electronic parts, at least a surface of each lead 11 is formed of a copper material as well as a blackened reduced coating 16 is positively formed on a face in contact with at least mold resin 30 of the copper material and a base 12.

Title: Film projector
Inventor: SATOU MINEKO
IPC: G03B27/50
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To prevent a situation that the shadow of a holder is reproduced on an image or an original range is erroneously detected by providing a light shielding plate for regulating a reading range in the case of reading the image on film other than specified size. SOLUTION: The light shielding plate 11 and a housing part 10 therefor are provided on an original platen glass 9. The plate 11 is usually housed in the housing part 10 and pulled out by holding a knob 12 in the case of shielding a projected image. A reading part performs reading operation concerning a range where a Fresnel lens exists. When the plate 11 is pulled out, image formation is performed only at a part where the light is not shielded by judging that the image does not exist at that part. Thus, the reading area of the projected image is optionally regulated, and the situation that the shadow of a mount for holding the film, for example, is read or the original area is erroneously detected is prevented. Then, faulty reading caused by excessive light quantity is also prevented.
