Title: Light transmissive medium, space light modulation method and space light modulation element
Inventor: SUGIYAMA YASUYUKI
IPC: G02F1/1333
Filed: 1997-05-13
Abstract: PROBLEM TO BE SOLVED: To provide remarkably rapidly responsible space light modulation method and space light modulation element by using a light transmissive medium orienting/ diffusing liquid crystal particulates with a specified maximum size or below. SOLUTION: The light transmissive medium 11 is formed by diffusing the liquid crystal particualtes 12 into light transmissive material 13. The maximum size of the liquid crystal particulates is made 150 nm or below from viewpoints of an extent of scattering due to a diffractive index difference between a liquid crystal particle and the medium, and response, etc., for applying a voltage. Then, electrodes 14 are arranged in the shape holding this light transmissive medium 11 between them. When a polarizing plate 1 is set so that polarization of 45 deg. for a (y) axis passes through, the polarization 4 of incident light passing through the polarizing plate 1 causes a phase difference in respective polarization components of y, z by the diffractive index anisotropy of the light transmissive medium 11 to become elliptic polarization 5.  Partial light transmits through this elliptic polarization 5 by the polarizing plate 1 and the polarizing plate 2 having a selective polarization direction 6 orthogonally intersecting with the polarizing plate 1 according to the elliptic rate of the elliptic polarization. That is, transmission light 20 is observed.

Title: Method for eluting heavy metal
Inventor: MATSUDA KIMIAKI
IPC: C01G49/00
Filed: 1988-05-18
Abstract: PURPOSE:To easily elute heavy metals from an ion exchange resin having functional groups from which heavy metals are not easily eluted by using an eluant contg. mercaptocarboxylic acid. CONSTITUTION:When heavy metals adsorbed on an ion exchange resin having functional groups not ensuring easy elution are eluted, an eluant contg. mercaptocarboxylic acid such as thiomalic acid or thioglycolic acid is used. The heavy metals belonging to the groups IB and VIII of the periodic table such as Au, Ag and Pt can be eluted with the eluant at a relatively low concn. and the elution rate and speed can be increased. The resin can be reutilized after elution and the expensive heavy metals are recovered and reutilized.

Abstract: PURPOSE:To fusion-connect a pipe and a pipe coupling securely by fitting a ring made of a leaf spring whose tube part is formed in a conical form making the inner side of the coupling main body in a smaller diameter, to the end of the entrance side of the pipe. CONSTITUTION:When a pipe 8 is inserted to the inside of a coupling main body 1, the pipe 8 expands the small diameter part 9 at the tip of a ring 3 by its tip at first, and enters to the inside further from the ring 3, and then, it is put in to the coupling main body 1 while cutting the outer peripheral surface of the pipe 8 which is the surface to be connected, by the first edge 13 of the tip small diameter part 9 of the ring 3, following the movement in the inserting direction. And when the pipe 8 is once fitted to the coupling main body 1, the removal of the pipe 8 is blocked while the relative positions of the pipe 8 and the coupling main body 1 in the diameter direction is fixed, by biting-in of the second edge 14 of the tip small diameter part 9 of the ring 3 to the pipe 8, even though the pipe 8 is going to move in the direction of removal, and the pipe 8 cannot be removed from the coupling main body 1.

Title: Manufacture of thick-walled steel pipe
Inventor: TAKIGAWA NOBUTAKA
IPC: B21D5/00
Filed: 1979-09-27
Abstract: PURPOSE: To prevent the generation of cracks at the end face of the steel plate undergoing the bending work, by previously removing the burr from the sheared edge of the plate before forming into the pipe, at manufacturing the steel pipe with the specified thick wall.  
     CONSTITUTION: At manufacturing the thick-walled steel pipe with the wall thickness shown by t/2R>2% (where, (t) is for the wall thickness, and R is for the neutral radius of the thick wall), the steel plate is sheared and is cold formed into the steel pipe; hereupon, only the burr on the side where the outer surface of the steel pipe coincides with the burr, is cut off or ground off. The removing process for the burr can be attained by only the chamfering work or by cutting off the whole edge. Besides, as the removing method, either one of the machine cut, the gas cutting, etc., can be employed. By the present method, the crack to be generated at the pipe end is perfectly prevented, so that the quality of the steel pipe is improved.

IPC: H04N19/587
Filed: 1993-04-27
Abstract: PURPOSE:To obtain the device with less picture quality deterioration even when the device is simplified by subsampling an anticipation residual error as to a frame of acyclic prediction so as to reduce number of picture elements thereby executing in-frame coding and reducing the quantity of arithmetic operation.

The input picture signal is delayed and given to an anticipation subtractor 4 till two I frames required for 2-thetaway anticipation are inputted to the buffer 3. The subtractor 4 subtracts an inter-frame anticipation signal given from a anticipation device 12 from the picture signal and an anticipation residual signal is fed to a sub sampler 5. The anticipation residual signal in the sampler 5 is filtered corresponding to the sub sampling and both the signals in the vertical and horizontal directions are interleaved. The anticipation residual signal is inputted to a buffer 6 at a speed in matching with the output of the sampler 5 and outputted to an in-frame coder 8 in matching with the processing speed of the in-frame coder 8 from buffer 6.

Abstract: PURPOSE:To obtain a prober which can accurately measure the discrepancy between a reference electrode and a probe needle in a short time, simply and without a mistake by a method wherein an intersecting point of scribing lines is recognized, the reference electrode of an IC chip situated in a predetermined position is recognized by means of the intersecting point and the electrode is aligned with a contact maker. CONSTITUTION:An IC chip 3 on a semiconductor wafer 1 is formed via scribing lines. Before a probing operation is executed, an intersecting point C of the scribing lines is recognized at an alignment operation to detect the discrepancy between the semiconductor wafer 1 and a probe needle 8 as a contact maker. A prober 4 accurately obtains the position of a reference electrode 18a on the basis of information on the distance between the intersecting point C of the scribing lines which is inputted to the prober 4 in advance and the reference electrode 18a on the IC chip 3. The reference probe needle 8 is moved to the position of the reference electrode 18a and can accurately be aligned. As a result, a situation that the reference electrode 18a is mistaken by an operator is not caused, and the alignment operation can be finished in a short time.

Abstract: PURPOSE:To determine the sequence of a nucleic acid with high accuracy by eliminating the distortion of an electrophoretic pattern by uniformizing the temp. of an electrophoretic gel, by preparing the support plate of the electrophoretic gel from electric insulating ceramics with high heat conductivity. CONSTITUTION:An electrophoretic separation gel 2 is held between two support plates 3 and both ends thereof are immersed in an electrolyte tank 1 and a high voltage DC power source 5 is provided to form an electric field in the gel 2. As the material of the supports 3 interposing the gel 2 therebetween, electric insualating ceramics with high heat conductivity, for example, SiC ceramics containing Be, B, Al or a compound thereof as a sintering aid is used. At this time, heat is generated during electrophoresis because of Joule heat but, because the support plate 3 is made highly heat-conductive, the temp. gradient in the gel is reduced. As a result, the distortion of the electrophoretic pattern of the specimen is not generated and the determination of the base sequence of the nucleic acid can be performed at a high speed with high accuracy.
