Inventor: SATO KAZUMI
IPC: F16C17/02
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To improve the durability of a dynamic pressure fluid bearing. SOLUTION: A shaft 2 integrally combined with a rotary polygon mirror 1 rotates in noncontact under the dynamic pressure of a fluid film formed between it and a sleeve 3. The dynamic pressure creating grooves 2a, 2b, etc., of the shaft 2 are formed by plating the main body 20 of the shaft 2 with a corrosion-resistant first plating layer 21, adhering a resist pattern to it, plating it with a second layer 22 and removing the resist pattern. The bottom faces of the dynamic pressure creating grooves 2a, 2b, etc., are constituted of the corrosion-resistant first plating layer 21, so that a bearing improves in its durability.

Title: Manufacture of semiconductor device
Inventor: MIYAZAWA HISASHI
IPC: H01L21/302
Filed: 1988-11-01
Abstract: PURPOSE:To prevent a high melting point metal film from peeling and yield of IC's from deteriorating by a method wherein when an electrode opening is to be etched on an insulation film on a semiconductor wafer, an opening located in a region corresponding to a dicing line is also etched together. CONSTITUTION:An opening 5 is made by patterning on a region corresponding to a dicing line together with an opening 4 for a source drain electrode on a resist film 3. Then, with the patterned resist film 3 used as a mask, an insulation film 2 is plasma-etched. In process of etching, since intensity of C-O coupling spectrum generated by reaction of mixed gas of CF4 gas and CHF3 gas and an SiO2 film is increased by at least 100 times compared with the case where only the opening 4 for the source drain electrode is etched, changes in spectrum intensity can be closely observed. This therefore enables appropriate etching by stopping etching at a point where the spectrum intensity rapidly decreases.

Title: Microfilm picture information reader
Inventor: SUZUKI HIROAKI
IPC: G03B27/32
Filed: 1984-12-28
Abstract: PURPOSE:To set automatically picture information with proper size to a display screen by detecting the vicinity of an edge of a read picture based on a signal from a read sensor and deciding a picture tip position to be outputted based on it. CONSTITUTION:The subscanning is progressed reversely from a home position XH up to a read start position XO in the pre-scanning stage, and when a subscanning address reaches the vicinity of a point XS (edge of picture area C), the picture signal is lost. The content of an address memory XS is not revised by an output of an edge detection circuit. When the reverse progress of the pre-scanning is executed up to an XO, a signal level is changed again and it is possible to update the XS, the X is a limit value to be set and depends on the relation between a retrieval mark and read accuracy and a picture information region 1. Then the relation of XS=XS-B as a picture signal, its location by ensuring a scheduled space B is inadvance from the edge address XS obtained in this way.

Filed: 1986-11-20
Abstract: PURPOSE:To prevent damage of a tape by independently applying braking to a supply reel and a winding reel at servo-off state depending on the tape winding state and the tape running state to make both the braking distance equal. CONSTITUTION:The tape running direction, a tape running speed, moment of inertia of supply reel and movement of inertia of winding reel are detected by a braking controller 21 at production of servo-off, and a reel having a longer braking distance is judged to be the winding reel 102 based on the moment of inertia of the supply reel 101 and the winding reel 102 at first, a brake instruction is issued to a winding reel drive circuit 17 to apply braking to a winding reel motor 2. Then a brake instruction is issued to a supply reel drive circuit 16 with a delay time in response to the ratio of the moment of inertia of the supply reel 101 and the winding reel 102 and the tape feed speed to apply braking to the supply reel motor 2. Thus, both the brake distance of the supply reel 101 and the winding reel 102 is made equal. Thus, the tape 103 is neither tensed nor slacked, then damage to be inflicted on the tape is prevented.

IPC: H03M1/10
Filed: 1985-12-10
Abstract: PURPOSE:To decrease the deviation of appearance probability of data codes, to conduct the test of an optional through-rate and to reduce a test time by adjusting the amplitude of a sinusoidal wave signal inputted to a test object A/D converter and giving a DC offset component to the sinusoidal wave signal whose amplitude is adjusted.

That is, the amplitude of the sinusoidal wave signal is set smaller than the input range of the DUT 6 to change the DC offset within the input range of the DUT 6 thereby setting the through-rate at each point of the DUT 6 to an optional value. Further, the amplitude of the sinusoidal wave signal is set larger than the input range of the DUT 6 to make the DC offset zero, thereby conducting the test without using a small through-rate part.

Title: Production of uo2 powder having improved fluidity
Inventor: HASEGAWA SHINICHI
IPC: G21C3/62
Filed: 1984-12-28
Abstract: PURPOSE:To obtain UO2 powder having improved fluidity free from clogging in a hopper in high yield, by drying ammonium biuranate precipitate into a specific water content, granulating the precipitate with an ammonium salt as a binder, drying the granulates at a specific temperature, and reducing the granulates through calcination. CONSTITUTION:UF6 is vaporized under heating, brought into contact with pure water and hydrolyzed to give an aqueous solution of UO2F. This aqueous solu tion or an aqueous solution of UO2(NO2)2 is blended with an aqueous solution of ammonia to form precipitate of (NH4)2O.2UO2 (ADU for short). The precipi tate is filtered off, washed, dried, and ground to give ADU powder, and the powder is reduced through calcination, to produce UO2 powder. In the above- mentioned operation, in the drying process of ADU precipitate, the water content of the ADU powder after drying is adjusted to 20-35wt.%, an ammonium salt accompanying the ADU powder is used as a binder to granulate the ADU powder, which is dried at 110-180 deg.C, and the particle diameter of the granules A after drying is adjusted to 50-1,500mu. UO2 powder having improved fluidity free from clogging in powder hopper is produced.

Title: Noncontact optical range finder and range finding method
Inventor: TAKAHASHI AKIRA
IPC: G01B11/24
Filed: 1992-09-22
Abstract: PURPOSE:To allow accurate measurement of distance upto the surface of a specimen regardless of the surface roughness by varying the spot size of projecting light depending on the surface shape of the specimen. CONSTITUTION:Light emitted from a light source 1 passes through a variable aperture diaphragm 3 and projected through an optical projecting system 2 onto the surface of a specimen 4. Spot size of the projecting light is regulated several times as large as the pitch of the surface roughness of the specimen 4 through the diaphragm 3. When the surface of the specimen 4 is as high as the surface 4a, the light beam impinges on a receiving optical system 5 while being shifted by an angle alpha1 to form a spot at position 6a of a position detector 6. Similarly, when the surface of the specimen 4 is positioned at 4b or 4c, the light beam is shifted by an angle alpha2 or alpha3 to form a spot at a position 6b or 6c thus producing a signal proportional to the intensity of received light. Since the spot size can be selected depending on the pitch of surface roughness of the specimen 4, accurate measurement of distance can be realized.
