Title: Manufacture of semiconductor device
Inventor: OKAMOTO YUTAKA
IPC: H01L27/11
Filed: 1989-08-31
Abstract: PURPOSE:To reduce the vertical stepped portion due to an interlayer insulating film of each polycrystalline silicon layer at an aluminum wiring contact part and hence improve step coverage of the aluminum wiring by providing a process of removing the interlayer film between wiring layers except the part which required dielectric strength. CONSTITUTION:SiO2 for example is deposited by a CVD process to form a first interlayer insulating layer 11. Then, a polyside structure second wiring layer 2 is deposited on the first interlayer insulating layer 11 for patterning. Thereupon, there is removed part of the second interlayer insulating layer 14 except the portion required for dielectric strength between the second wiring layer 2 and a third wiring layer 15. Hereby, there can be reduced the vertical stepped portion of a contact hole on the side of the second wiring layer 2 side where an aluminum contact is formed, thus ensuring satisfactory step coverage.

Inventor: HAMADA AKIYOSHI
IPC: G02B7/34
Filed: 1986-09-24
Abstract: PURPOSE:To execute a focus detection even by a dark image forming optical system, by providing a luminous flux control means for bringing an adjacent side part of each split luminous flux to an incidence control at the time point when the luminous flux is split or thereafter. CONSTITUTION:An image forming luminous flux 1 which has passed through a first image forming means is split by splitting means 3, 4 and thereafter, turned toward second image forming means 5, 6, respectively, by different optical paths. As for each split luminous flux 1a, 1b, an incidence to the second image forming means 5, 6 of the mutual adjacent side parts is controlled by a luminous flux control means 8 at the time point of the split, or before reaching the second image forming means 5, 6 after the time point of the split. In this way, as for each second image forming means 5, 6, right and left two- split ranges each related to the whole range of the maximum image forming luminous flux are made incident separately on the second image forming means 5, 6, can be condensed to different positions on a photodetector 7, the sum of those condensing luminous flux ranges becomes equal to the image forming luminous flux, and even in case of an image forming lens whose F-number is large, a sufficient contrast for detecting a focus is obtained.

Title: Half-open shutter device
Inventor: SATO YOSHINOBU
IPC: G03B9/36
Filed: 1989-08-31
Abstract: PURPOSE:To perform highly accurate shutter control by releasing a shutter under full-power-feed control in its initial stage and then by constant speed control in following stages. CONSTITUTION:When a shutter blade begins to be opened, a signal associated with the motion of a shutter plate 21 as an opening member is detected by a photointerrupter 11 and a position detection signal (e) is inputted to a control circuit 3 through a photointerrupter waveform shaping circuit 10. The control circuit 3, when receiving a signal indicating the end of a motor full-power-feed time from a timer circuit 4, switches current control over the shutter release to the constant speed control. For this constant speed control, the voltage is reduced when the releasing speed of the shutter blade analyzed with the signal (e) is larger than a predetermined target value to reduce the releasing speed, but when the releasing speed is less than the target value, the voltage is increased to accelerate the releasing speed.

Title: Composite perception sensor for robot finger
Inventor: NAKAMURA KUNIO
IPC: G01J5/12
Filed: 1991-09-05
Abstract: PURPOSE:To realize a highly durable and easily miniaturizable composite sensor to enable a finger of a robot to perceive both the pressure and the hot and cold sense by using a pyroelectric organic film. CONSTITUTION:A hot and cold sensing part 2 of a pyroelectric organic film 1 is set at a part recessed from the contact face with an object. The infrared radiation from the object is detected in a contactless manner without receiving the pressure resulting from the contact, and the temperature data alone can be detected. Reading of signals is controlled by a signal from a pressure sensing part 5, and the hot and cold data is obtained only when the robot grasps the object. Accordingly, a composite perception sensor for finger which is highly durable and easily turned compact is obtained.

Title: Laser beam irradiation si surface treating device
Inventor: AOTO NAHOMI
IPC: H01L21/302
Filed: 1985-10-11
Abstract: PURPOSE:To reduce damage to and permit cleaning the surface of an Si substrate after etching at the same time while performing etching on the Si substrate at higher speed by providing a heater in a target. CONSTITUTION:A heater 15 is provided in a target 14 whereon an Si substrate 13 is set up and a current is permitted to pass through a current introducing terminal 16. Inert gas, fluorine gas, chlorine gas, hydrogen gas or the mixed gas of them is irradiated on the Si wafer 13 on the target 14 from an ion source in the same way as normal ion etching and an etching is performed. The chlo rine gas, fluorine gas and hydrogen gas are adsorbed in the Si substrate surface in atmospheres of these gases, or in a vacuum wherein these gases have been filled and then are exhausted. In case there exist an Si-Cl bond, an Si-H bond and an Si-F bond on the surface, there is a large possibility that Si chloride, Si hydride or Si fluoride on the surface is desorbed by a temperature rise or the irradiation of a CO2 laser beam 1 because the back bond of Si is weaker than that of a normal Si-Si bond. At this time, contaminated impurities being adsorbed firmly on the surface are desorbed along with Si on the surface and the surface is cleansed.

Abstract: PURPOSE:To obtain a favorable crystalline resin molded article free from sink mark and having a thick wall part and a thin wall part, by a method wherein a melted crystalline resin is charged into a metallic mold with heating under pressure, is cooled at a specified temperature and a specified pressure, and then a molded article is taken out. CONSTITUTION:The metallic mold is heated to a temperature of not lower than the crystallization starting temperature of the crystalline resin by passing hot water through passing holes provided in supporting bases 7, 8. Then, a metallic male mold 5 is raised, and a melted form crystalline resin blank material 6 is charged into a metallic female mold 4. Next, the female and male molds are pressed to a pressure of 2- 10kg/cm<2> by a pressure molding machine so that the resin blank material fills up parts which constitute the thick wall part and the thin wall part after molding. Subsequently, the metallic mold is cooled by passing cooling water through the passing holes provided in the supporting bases or the mold, thereby cooling the resin blank material, and when the internal temperature of the thin wall part of the blank material reaches a temperature approximate to the crystallization starting temperature, the pressure exerted on the mold is raised to 25-50kg/cm<2>. When the internal temperature of the thick wall part reaches a temperature approximate to the crystallization finishing temperature, the molded article is taken out from the metallic mold.

Title: Brushless motor equipped with flat core
Inventor: SUNAGA SOSUKE
IPC: H02K21/12
Filed: 1991-08-12
Abstract: PURPOSE:To sustain sufficient characteristics by bending a salient pole, at the tip thereof, into reverse L-shape and forming a field magnet to have a reverse L-shaped cross-section thereby preventing fluctuation of rotor during rotation. CONSTITUTION:Salient pole 9a of a stator core 9 is bent downward, at the tip thereof, into a reverse L-shape. A field magnet 10 opposing through an air gap to the reverse L-shaped salient pole 9a is a plastic magnet having reverse L-shaped cross-section copying the salient pole 9a and molded integrally with a case 5. Since the planar part of the reverse L-shaped magnet 10 is contained in an unnecessary space defined by winding an armature coil 2, flux is partially generated in the axial direction from the field magnet 10. A rotor R including the field magnet 10 is thereby attracted to the stator core 9 with relatively strong urging force thus eliminating unstable vertical fluctuation during rotation.
