Abstract: PROBLEM TO BE SOLVED: To attain a laminate integration and electric interconnection between wiring layers by a continuous press of a laminate of conductive metal foils to plastically deform the top ends of conductive bumps to connect them to the conductive metal foil surface, forming through-type conductor wiring parts, using a continuous press. SOLUTION: A roll-like electrolytic Cu foil is a support base. Ag paste is charged in recesses of a cylindrical roller surface, the roller is positioned to the foil to transfer a bump forming compsn. to the surface of the support base 1 and it is heated to form conductor bumps 2. A synthetic resin sheet 3 is prepared, faced the formed bumps 2 and primarily pressed to pierce the bumps through the sheet, the roll-like electrolytic Cu foil 4 is laid on the bump-pierced surface and secondarily pressed by a continuous press to easily plasticize the resin sheet and plastically deform the top ends 6 of the bumps due to the secondary press of the bump top ends to the conductive metal foil surface. Thus it is possible to attain a reliable laminate integration and electric interconnection between wiring layers at high reliability.

IPC: G01B17/02
Filed: 1983-07-01
Abstract: PURPOSE:To prevent the leading-in phenomenon and perform measurement with a high precision for a long time by providing a transducer with a leading-in preventing supporting roller which is brought into contact with a carrying roller of an object to be measured and is turned. CONSTITUTION:Supporting rollers 32 are set in both side parts of a transducer 2. In the initial stage of the leading-in phenomenon, spacer rollers 8 are led in the ingot advance direction of an arrow (b), and the transducer 2 is moved in the same direction of the arrow (b) in accordance with this leading, and supporting rollers 32 are brought into contact with carrying rollers 4 and are turned. Therefore, the movement of the transducer 2 is stopped. The transducer 2 is brought into contact with carrying rollers 4 through supporting rollers 32, and the frictional resistance is extremely low because of rolling contact. A pressing force f2 is generated in such degree that it can be ignored; and even if the phenomenon that spacer rollers 8 are led in the ingot advance direction of the arrow (b) occurs, the movement of the transducer 2 is stopped.

Title: Optical information reproducer
Inventor: NAKANISHI TOSHIHARU
IPC: G06K7/12
Filed: 1978-09-26
Abstract: PURPOSE: To reduce the occurrence frequency of the crosstalk by securing reproduction of the mark information at the different positions from each other for the adjacent pages of the optical recording medium which records the information and the mark information in the munus unit.  
     CONSTITUTION: In case the reproduction is given to the information within each page on optical recording medium 11, center position X and Y coordinate position of the page are referred to as, for example, X 0  and Y 0 , along with the X and Y coordinates at the center position of the light set up at the reproduction starting time referred to as X 1  and Y 1  respectively. Thus the deflecting amount of light deflector 2 is set to such initial value as to secure the inequalities of X 0 >X 1  and Y 0 >Y 1 . The deflecting amount to receive the initial set is decided based on the X and Y coordinate position signals which are supplied to light deflection driving circuits 29 and 30 to the X and Y directions each. Then the mark information within the minus unit is detected. And based on the detection signal, the correction is given to the deflecting amount in the X and Y directions of deflector 2 to secure the coincidence for center position between the munus unit and the light. In such way, the occurrence frequency can be reduced for the crosstalk.

Title: Performance testing method of adsorbents mainly composed of solid bases
Inventor: IGARI YOSHIMASA
IPC: B01D15/00
Filed: 1977-10-01
Abstract: PURPOSE: To enable the performances of adsorbents mainly composed of solid bases for water treatment to be readily tested by charging the adsorbents into an aqueous acid solution to allow hydration reaction to take place and plotting the pH changes of the solution occuring at that time with respect to the time.  
     CONSTITUTION: An inorganic base adsorbent such as MgO is charged in an aqueous acid solution of preferably 0.01 to 0.05M concentrations. Upon lapse of a fixed induction period (a), reaction induces rapidly and pH sharply rises. After the lapse of this initial reaction period (b), the post reaction period (c) in which pH rises gradually begins and in the final the pH reaches the theoretical balance pH conforming to the intensity of basicity of the treating agent. In this way, with the agent of good performances, the periods (a) thru (c) are clearly identified, wherein the period (a) is short and a drastic change in pH is observed in the perios (b). With the treating agent of poor performances, the distince identification of the periods (a) thru (c) is undiscernible and there is no drastic change in pH. From the relationship of pH/time, the performances are readily determined

Abstract: PURPOSE:To facilitate the compression of text data for displaying a Japanese language document by rearranging characters in order of a larger frequency of a appearance and registering them in a file, and outputting a value of location from the head of the registered characters as compressed text data. CONSTITUTION:In a character-string of text data to be compressed, characters are sorted in order of a larger frequency of appearance, and each character is registered in a file 7 in sorted order. Subsequently, a value of location on the file 7 of each registered character is obtained, and by the value of location, each character of the text data to be compressed is represented. That is, each character of the text data to be compressed is converted into the value of location. Each converted character is outputted to a compressed data text file 8 as compressed text data. By excuting such data compression, the memory capacity for storing the compressed text data can be made small.

Title: Deflection yoke
Inventor: OTSU SHINJI
IPC: H04N3/16
Filed: 1993-04-22
Abstract: PURPOSE:To make the deflection yoke small by placing a cancel coil to a terminal board of the deflection yoke or a printed circuit board. CONSTITUTION:A drum core 8a of a cancel coil is placed to a front side of a tip of a terminal board 6a fixed to a tail end 5a in the deflection yoke 10a so that a center line is set to a right angle. When a deflection current is supplied to the deflection coil, a magnetic field is generated to deflect an electron beam and a picture is obtained on a screen. In this case, a deflection magnetic field is leaked to the outside of the deflection yoke. The cancel coil generates its magnetic field to cancel the leaked magnetic field. Thus, the size of the cancel coil is made small and the entire deflection yoke is made compact.

Abstract: PROBLEM TO BE SOLVED: To stably and separately feed various sheets by changeably constituting an actuating outside diameter of a retard rotary body for rotating the sheets in the returning direction by pressing the sheets to a feed rotary body. SOLUTION: In a sheet required to set larger retard force by a retard roller 25 because of being easily fed in diplicate, the claw part 41b2 is removed from the locking part 41a2, a movable collar 41b is moved in the arrow D direction, and the claw part 41b2 is locked again on the locking part 41a2. An interval between a fixed collar 41a and a movable collar 41b expands thereby, a roller member 40 supported by the inclined parts 41a1, 41b1 is elastically deformed, a radius R up to the outer periphery reduces, and retard force increases. While, in a sheet required to set retard force small, the movable collar 41b is moved in the arrow E direction to be fixed. An interval between the fixed/movable collars 41a, 41b narrows thereby, the roller member 40 is deformed, the radius R up to the outer periphery enlarges, and the retard force reduces.
