Title: Air blower
Inventor: TOMOHIRO TERUHIKO
IPC: F04D29/18
Filed: 1992-01-30
Abstract: PURPOSE:To provide the reduced noise and thickness of a small-sized axial and mixed flow blowers, and. improve pressure characteristics. CONSTITUTION:Because the front edge 8 and the rear edge 8b of a blade 8 are made to be a protruding curve on the downstream side, the meridian sectional shape of the blade 8 declines toward the downstream side around a hub 7, and inclines toward the upstream side at, the chip side when a blade wheel 6 is rotated around a rotating shaft. Because the inclination of the blade 8 is made larger on the chip side where flow rate and centrifugal force are high, the effect of restraining the development, of a border layer becomes large. Besides, because the blade rear edge 8b is formed into the curve with protruding part on the downstream side, the blade rear edge protrudes toward the downstream side from the line linking the hub and the downstream edge of an orifice even when the downstream edge of the orifice 9 is made to meet the downstream edge of the chip. With this constitution, force to send the flow toward the downstream side of the orifice 9 becomes stronger, thus it is possible to improve side of the orifice 9 becomes high load even when the air amount and the low noise are realized by using a thin orifice 9.

IPC: G03B17/20
Filed: 1996-01-30
Abstract: PROBLEM TO BE SOLVED: To display which format should be selected by using a recognizable index and also to make possible to accurately confirm a format area in the case a new format is selected, by displaying an intersection of 2nd and 3rd format areas on a screen. SOLUTION: A display KP showing the intersection of a format C and a format P is displayed as a point to a format H visual field frame. The intersection KP is displayed only as a point in the format H, so that the inconvenience at photographing is reduced. The display of the intersection KP is fixed, and in this case, the display is constituted of a liquid crystal electrode pattern. A visual field pattern HL showing the format H is formed to a pattern by vapor-depositing a metal film on the surface of liquid crystal glass, but in the case of constituting the frame HL, it is permitted to arrange another mask on the liquid crystal glass. A display C1 showing a boundary area of a format C and a display PL showing a boundary area of a format P, are displayed by liquid crystal as a linear pattern linking the intersections when each format is selected.

IPC: H01L21/306
Filed: 1986-01-27
Abstract: PURPOSE:To improve the precision of the pattern of the contact hole of the oxide film of the thinner one of Si oxide films by a method wherein, in case contact holes are formed in the Si oxide films having different film thicknesses by etching, a sidewall is formed by heat-treating a photo resist after the contact hole of the oxide film of the thinner one is opened and an etching is performed on the oxide film of the thickner one. CONSTITUTION:A pattern is formed on an oxide film 2 on the element forming region of an Si substrate and an Si oxide film 3 on the element isolation region of the Si substrate using a P-type photo resist 4 and the oxide films are etched using this photo resist 4 as a mask until a contact hole 7 of the Si oxide film 2 of the thinner one is opened. Then, if this Si substrate 1 is heated at a temperature of 180 deg.C for 30min, the photo resist 4 is softened and sags, whereby a sidewall 16 is formed on the inner peripheral surface of a side etching part 9. After such a heat treatment, the residue of the oxide film 3 of the thicker one is opened to form a contact hole 8. Thereby, in case the contact holes are simultaneously opened in the Si oxide films whose film thicknesses are different from each other, the precision of the pattern of the contact hole of the oxide film of the thinner one can be improved.

Title: Recording medium
Inventor: ITO HIROYUKI
IPC: G11B7/245
Filed: 1986-01-29
Abstract: PURPOSE:To obtain a recording medium which permits semi-permanent preservation of record and rewriting by consisting a recording layer of a specific thermotropic cholesteric mesomorphic glutamic acid ester copolymer. CONSTITUTION:The film of the recording layer consists of the thermotropic cholesteric mesomorphic glutamic acid ester copolymer expressed by the formula and forms hardly no liquid crystal structure at about an ordinary temp. without having the power to selectively reflect specific light. However, said film forms a cholesteric liquid crystal in a liquid crystal forming temp. region when the temp. thereof is increased by the irradiation of laser light thereon. The irradiated micro-region is quickly cooled and the cholesteric liquid crystal structure is fixed after the laser light moves. The record is thus held. The recording layer has the power to selectively reflect the light of a specific wavelength according to the cholesteric pitch when the cholesteric structure is once formed and therefore, the recording conditions are preliminarily so set that the wavelength conforms to the wavelength of the reading out laser light. The reading out is thereby easily executed by the difference in the reflectivity or transmitting.

Filed: 1998-01-13
Abstract: PROBLEM TO BE SOLVED: To provide a spindle motor in which the shake of a non-rotational synchronization component is small, which has a small starting torque, which is usable even in an inverted state and, moreover, which is excellent in impact resistance and whose efficiency is satisfactory. SOLUTION: Relating to a spindle motor device for surface opposition type disk, a damping member 100 is laid between a stator core 34 and a supporting frame 31. Since this device has such a constitution, the vibration energy of the vibration of the stator core 34 which is to be generated by rotor magnets 45 is converted into thermal energy by the damping member 100 and the vibration is damped. As a result, since the noise of a motor is lowered and also a vibration to be transmitted to a mounted disk can be damped, the vibrantion of the disk becomes smaller and the recording density of the disk is enhanced.
