Abstract: PURPOSE:To improve accuracy in detection by installing a pair of electrodes, provided at a lubricating oil surface detector for detecting the lubricating oil surface by the change of the electrostatic capacity between a pair of electrodes, on a lubricating oil exhaustion level as well as parallel to the oil surface. CONSTITUTION:The flange part bottom face of a conductive sub-bearing 15 is positioned parallel to the lubricating oil surface 16a as well as on a lubricating oil exhaustion level (b). This bottom face is used as one electrode of a pair of parallel plane electrodes, and the other electrode 22 is fitted through an insulating spacer 21. This pair of parallel plane electrodes are thus installed parallel to the oil surface 16a on the lubricating oil exhaustion level (b). The electrode 22 is provided with holes 23 of specified diameter bored plurally. The electrostatic capacity value of an oil surface detector 20 and the oil surface 16a has an inverse proportional relation, and the electrostatic capacity value is changed largely in the vicinity of the exhaustion level (b), and detection sensitivity becomes large. Furthermore, the flow of lubricating oil becomes smooth at the holes 23 of the electrode 22 to prevent the generation of residual lubricating oil between the electrodes and thereby improve accuracy in detection.

Title: Bipolar transistor
Inventor: ISHIBASHI TADAO
IPC: H01L29/737
Filed: 1987-01-30
Abstract: PURPOSE:To obtain a bipolar transistor operating at the high speed by extending a base electrode layer from the surface of a base semiconductor layer to the surface of the first insulating layer part, and by extending an emitter electrode layer from the surface of an emitter semiconductor layer to the surface of the first insulating layer part through the surface of the second insulating layer part. CONSTITUTION:A base electrode layer 6 is extended at the opposite side to the side of an emitter electrode layer 7 from the surface of a base semiconductor layer 3 directly to the surface of first insulating layer part 8a of an insulating layer 8. The emitter electrode layer 7 is extended from the surface of an emitter semiconductor layer 4 to the surface of the first insulating part 8a through the second insulating part 8b of the insulating layer 8. As this configuration makes a base and collector junction area between the base semiconductor layer 3 and a mesa part 2b of a collector semiconductor layer 2 smaller sufficiently and also makes the base resistance value lower, its characteristics permit a bipolar transistor to be operated at the high speed.

Filed: 1990-01-31
Abstract: PURPOSE:To make an excellent optical scanning superior in print quality by providing a varifocal semiconductor laser light source, a collimator lens, a deflecting means, and a 1st and 2nd image formation system, and a control means. CONSTITUTION:Luminous flux projected from the collimator lens 3 has its luminous flux diameter controller by an aperture 4 and is incident on the 1st image formation optical system 5. The luminous flux which is transmitted through the image formation optical system 5 is reflected by a deflecting and reflecting surface 7 and made incident on a surface 10 to be scanned through the 2nd image formation optical system 9. Here, when the focus is displaced owing to variation in the radiation angle of the varifocal semiconductor laser light source 1 and a point P shifts to P' by a distance  , the image formation position in the subscanning direction shifts by beta<2>  by using the composite lateral magnification beta of the cylindrical lens 5A and a long-sized cylindrical lens 9. For the purpose, arcuate curvature of field is considered as a func tion of the deflection angle theta, and the radiation angle of the laser light source 1 is controlled so that beta<2>  =W(theta), thereby compensating the curvature of field in the subscanning direction excellently. Consequently, the optical scanning with high density can be made.

Title: Pressure measuring device of plasticizing material in injection molding and injection molding machine
Inventor: ODATE TAKAO
IPC: B29C45/77
Filed: 1989-01-31
Abstract: PURPOSE:To precisely measure the pressure of a plasticizing material in both a measuring process and injection process by measuring the pressure of the plasticizing material by a pressure sensor arranged on the rear or the front of an injection plunger. CONSTITUTION:A plasticizing material melted and plasticized by a preplasticizing mechanism 20, for example, molten resin is sent to a resin rich area 18 from the preplasticizing mechanism and a ram 34 and injection plunger 22 are moved backward to an initial position. Then even after filling of the resin rich area 18 with the molten resin, the preplasticizing mechanism 20 keeps sending the molten resin and the injection plunger 22 is pressed rightward by force of the molten resin. The resin pressure pressing the injection plunger 22 rightward presses a pressure sensor 32 of the rear of the injection plunger and the resin pressure is measured by the pressure sensor. The pressure of the plasticizing material in a measuring process is obtained easily in this manner. The resin pressure in the injection process acts upon the injection plunger 22 as reaction force, measured by the pressure sensor 32 of the rear of the injection plunger and also a variation of the resin pressure is secured reliably.
