Title: Scroll fluid machine
Inventor: KAAI MASAFUMI
IPC: F04C18/02
Filed: 1990-02-20
Abstract: PURPOSE:To reduce the power of a motor or the like required for friction welding by forming one of the end plates of fixed and revolving scrolls and the lap part thereof with different materials, relatively turning the end plate and lap part kept in contact at jointing surfaces and jointing the end plate and lap part to each other with heat generated due to friction. CONSTITUTION:The end plate 8 and lap part 9 of a revolving scroll 8 are formed with different materials. While the end plate 8 being kept in contact with the lap part 9 at jointing surfaces, the lap part 9 is turned with the predetermined turning radius epsilon relative to the end plate 8 for generating frictional heat, thereby melting and welding the jointing surfaces under pressure in an axial direction. By keeping the turning radius epsilon of a crankshaft 28A at less than a half of the wall thickness gamma of the lap part 9 in keeping the contact of the edge 9A of the lap part 9 with the front 8A of the end plate 8 and slidably turning the aforesaid lap part 9, motor torque transmitted to the jointing surfaces via a rotating shaft 28 or the like can be efficiently converted to frictional heat, and the time of exposure of the jointing surface of the front 8A to the atmosphere can be shortened. As a result, the jointing surfaces of the end plate 8 and lap part 9 can be effectively heated.

Title: Pattern feature extractor
Inventor: ASAI HIROSHI
IPC: G06K9/00
Filed: 1979-04-02
Abstract: PURPOSE: To simplify the collation of features by extracting as features, enabling the discrimination or collation of a fingerprint, the number of swell lines between feature points near a pattern and the congestion degree of feature points, in addition to feature points of the pattern and directions at the points.  
     CONSTITUTION: Fingerprint picture 0 is scanned in two dimensions, quantizing scanner 1 converts picture shade information at each quantization point into an quantized signal, and core-line generating unit 2 converts the quantized signal output synchronizing with the scan of this unit 1 into a core-line pattern. This core-line pattern is applied to feature-point detector 3 to detect the position of the pattern feature of a partial pattern consisting of adjacent picture elements of the core-line pattern signal and the position is stored in core-line pattern memory 7. Further, direction detector 4 detects and applies the direction of the pattern feature to memory 7 and relation detector 5 regards respective pattern features as center features to select other pattern features surrounding them as relation features, and consequently the number of swell lines residing between features and the congestion value of center features are detected and applied to feature memory unit 6.

Title: Commutation circuit of thyristor
Inventor: MIMURA MUNEHIKO
IPC: H03K17/732
Filed: 1978-04-04
Abstract: PURPOSE: To reduce the variation in the base current, to reduce the power loss of commutation transistor and to obtain low cost and small sized circuit, by inserting the additional inductance to the collector current path of the transistor.  
     CONSTITUTION: During the commutation period from the thyristor CR to TR 1 , the voltage drop due to the resistor Re and inductance Le of wiring being the common impedance to which the base current IB and the collector current i c  pass, is caused to increase the ON voltage of TR 1  resulting in increasing the power loss. Accordingly, even during the commutation period, if the desired base current is supplied, since excessive base current is caused after commutation, the variation in the current is reduced by inserting the additional inductance in series with the path of the thyristor current ICR and the inductance L o  in series with the path of the collector current i c  of TR 1 , to reduce the power loss of the commutation TR 1 .

Title: Resist pattern forming method
Inventor: ARAYA TATSUJI
IPC: G03F7/30
Filed: 1992-02-27
Abstract: PURPOSE:To prevent the generation of resist residues after development without impairing sectional shapes and dimensional accuracy by exposing and developing a resist film via a mask on a substrate, then subjecting the resist film to additional exposing and developing. CONSTITUTION:A positive resist is applied on the surface of the substrate and is then baked to form the resist film 2 at a desired film thickness. The resist film 2 is subjected to UV ray exposing via the mask 3. The exposing time of the time is set at about 80% of the optimum values of the sensitivity and film thickness of the resist film 2. The resist film is thereafter developed with a prescribed developer. Since the exposing time is set slightly lower, the resist residues are generated on the substrate 1. The entire surface of the resist film 2 is then irradiated with the UV rays for a short period. The exposing time is set at about the difference between the optimum values of the photosensitivity and film thickness of the resist film 2 and the previous exposing time. The resist film is thereafter developed by the prescribed developer. The resist residues on the substrate 1 are annihilated such developing. Even more, the collapse of the sectional shape and the degradation in the dimensional accuracy in the resist patterns are obviated.

Title: Manufacture of pva solution for phosphor slurry
Inventor: MATSUYAMA HIROMI
IPC: B05D7/24
Filed: 1996-02-28
Abstract: PROBLEM TO BE SOLVED: To increase the stirring speed and avoid foaming by preventing a polyvinyl alcohol(PVA) solution for phosphor slurry from being kept at the stirring state at a high temperature for a long time, and setting it to the stationary state before foaming occurs. SOLUTION: Stirring vanes in a tank are rotated by a motor at 32rpm higher than the conventional 28rpm to stir PVA and water. The mixture is first stirred for 30min without being heated, it is stirred and heated to the prescribed temperature (e.g. 80 deg.C) for about 120min, then it is retention-heated and stirred for heat retention (80 deg.C) for 70min, for example. The mixture is stirred for 5min and kept stationary for 10min, and the retention heating and stirring is intermittently repeated for 70min. The mixture is then stirred while being cooled to the room temperature, and it is kept stationary to complete a PVA solution. The solubility of PVA into water is increased, and homogeneity is improved. The problem of the stepchild-like or gelatinous PVA caused by heterogeneity can be prevented.
