Title: Preparation of concentrated solution of platelet, its device and part
Inventor: IRIGUCHI NORIO
IPC: A61K35/14
Filed: 1980-10-03
Abstract: PURPOSE: To obtain a concentrated solution of platelet, by putting a porous filter membrane between the first chamber having an introduction path for polyplatelet plasma and the second chamber having an discharge path for nonplatelet plasma, followed by concentrating the polyplatelet plasma.  
     CONSTITUTION: The blood is fed to the centrifugal separator 13, and centrifugal force is applied to it to give polyplatelet plasma as a supernatant liquid. The fixed delivery pump 7 is operated, the polyplatelet plasma is introduced from the introduction path 2 to the first chamber 3, nonplatelet plasma is filtered by the porous filter membrane 1 (preferably the maximum pore diameter of ≤2μ, especially 0.1W 0.5μ), the nonplatelet plasma is discharged from the second chamber 5 and discharging path 4, and the polyplatelet plasma is concentrated by the first chamber 3. When the concentration is insufficient, the fixed delivery pump 10 is operated and it is joined with unconcentrated polyplatelet plasma and concentration is carried out again. Erythrocyte and leucocyte as a sedimentation component in the centrifugal separator 13 are returned from the blook tube 14 to the outside, and the concentrated polyplatelet plasma is discharged by operating the fixed delivery pump 8, thus to make continuous treatment possible.

Title: Manufacture of semiconductor device
Inventor: MANO TOSHIHIKO
IPC: H01L21/76
Filed: 1979-10-25
Abstract: PURPOSE:To attempt the high integration of elements by forming a P type stopper in a P type well by self-matching for self matching P type and N type wells. CONSTITUTION:SiO2 14 and Si3N4 15 are placed on an Si substrate 13 for opening. An N well 17 is made by applying a resist mask 16 on the Si3N4 15 and by ion implantation. The mask 16 is removed and SiO2 18 is made by performing selective oxidation by the mask 15. The mask 15 is eliminated and the removal of etching is applied to the SiO2 14 to leave SiO2 19. A P well 20 is made by ion implantation by the mask 19. The P well 20 is covered with SiO2 21 and a resist mask 22 is applied to the P well 20 to make a P type stopper 24 by selectively opening. In this composition, the P stopper will be formed by self-matching in addition to self matching P and N wells. So, the provision of mask alignment margin is unnecessary. Therefore, well area will be reduced by about 30 percent.

Title: Measuring apparatus of spectral sensitivity of optical sensor
Inventor: ASANO NOBUYUKI
IPC: G01J3/42
Filed: 1981-09-02
Abstract: PURPOSE:To perform measurement of spectral sensitivity in a short time, by detecting the light quantity of the one hand light having a different wavelength by a light quantity detector for measuring the spectral sensitivity and projecting the other hand light to an optical sensor. CONSTITUTION:Outputs of a light quantity detector 8 and a sample 9 are obtained under a dark condition by closing an optical path with an optical path shutter 4 and next, the outputs of the sample 9 and the detector are obtained by opening the optical path and controlling the light quantity at every wavelength. Further, the surface light quantity of the sample is obtained by subtracting the output at the time of the dark condition and also, multiplying a correction factor for obraining the surface light quantity of the sample by the output of the detector 8 and spectral sensitivity is obtained from sample output/light quantity. This process is repeated at every each wavelength. Hereby, measurement of the spectral sensitivity is measured in a short time because both outputs of the detector 8 and the sensor 9 are detected at the same time.

Title: Golf ball
Inventor: HANAZAKI YOSHIICHI
IPC: A63B37/00
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To perform hitting while avoiding an obstacle even when it is present in front of a target spot because a golf ball is curved in a prescribed direction and flown when it is hit by a normal hitting method by forming the surface of a spherical body so as to generate a difference in air resistance on the respective surfaces of the semispherical parts of the spherical body. SOLUTION: For this golf ball 1, many small circular dimples P are formed on the entire surface area of the semispherical part A and the almost circular area for which a pole E is a center of the semispherical part B is turned to an area N1 for not forming the dimples P. Then, when the area N1 is placed so as to face a golfer and it is hit by the normal hitting method, since the air resistance received on the area N1 is large at the time of flying, the air resistance received by the semispherical part B becomes large compared to the air resistance received by the semispherical part A and the golf ball 1 is curved in the direction of the semispherical part B, that is a left direction. Thus, in the case that a pond or a bunker or the like is present in front of the target spot on a golf course, hitting is performed in a curve shape so as to avoid it even by the normal hitting method.

IPC: H01J63/08
Filed: 1984-07-04
Abstract: PURPOSE:To enable given degrees of excitation and emission to be constantly produced during lighting by preventing electrons passing through the anode from remaining around the envelope wall. CONSTITUTION:A thermion-radiating cathode 1 and a meshy anode 2 located in front of the cathode 1, are installed in an airtight spherical envelope 3 made of transparent glass. The envelope 3 is charged with a gas at low pressure which can emit excited light when electrons strike it. The inner surface of the envelope 3 is coated with a phosphor as necessary. A second anode 4 consisting of a rough meshy conductor is installed along the inner surface of the envelope 3. The first and the second anodes 2 and 4 are adjusted to have almost equal electric potentials by an external circuit. By thus installing the second anode 4 catching electrons near the envelope wall, it is possible to constantly produce a given degree of emission during lighting.

Abstract: PURPOSE:To eliminate selecting operation of a cooking menu even if an operation dial is erroneously slightly rotated when a depression for starting cooking is conducted after the menu is selected by rotating the dial. CONSTITUTION:A control circuit 11 sequentially displays a plurality of cooking menus selectively when an operation dial 10 is rotated, and sets, when a desired menu is selected, heating cooking conditions corresponding thereto. The circuit 11 becomes a state for receiving an input of starting cooking by a depression when a predetermined time T is elapsed from when the dial 10 is finally rotated Since the circuit 11 receives an input by the rotation of the dial 10 at a rotating amount of a predetermined angle or more in this state, the set menu is not altered even if the dial 10 is erroneously slightly rotated upon depressing.

Title: Production of composite sintered parts
Inventor: HAYASAKA TADAO
IPC: C22C33/02
Filed: 1981-09-04
Abstract: PURPOSE:To obtain iron-copper-base sintered parts which are firmly joined into one body by combining a green compact provided with boss parts contg. substantially no B and a green compact provided with hole parts contg. B above prescribed ratio, both of which consist essentially of iron and copper respectively and sintering the combined green compacts. CONSTITUTION:Of the above-mentioned two green compacts to be joined, the green compact provided with bosses is of the compsn. contg. essentially of iron and copper and contg. no B or contg. <0.03% B. On the other hand, the green compact provided with hole parts consists essentially of iron and copper and contains >=0.03% B. Both are fitted to each other and are sintered, whereby intended iron-copper-base sintered parts are obtained. In other words, the former expands on progression of sintering for the characteristics of the iron-copper- type green compact, but the latter shrinks by suppressing the copper expansion phenomenon by the effect of B. Since the sintering progresses while the joining surfaces of both are held in tight contact with each other, the iron-copper sintered parts which are firmly joined to one vody are obtained.
