IPC: B41F27/00
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To enable the tip of an anvil to be drawn out of the formed bend of a printing plate with a simple construction. SOLUTION: On each of anvils 104, 106 on which the vertical end parts of a printing plate 12 are positioned and arranged respectively, legs, which are mounted on both ends of the anvil in the crosswise direction of the printing plate 12, are pivotally supported by a bracket through a shaft 260.

Title: Cathode-ray tube
Inventor: FUKUDA KUMIO
IPC: H01J29/50
Filed: 1981-04-02
Abstract: PURPOSE:To make the correction of the degree of the concentration of electron beams variable by carrying out the concentration of the electron beams by installing an auxiliary electrode surrounding electron beam paths between a third and a fourth grid electrode, which constitute the main lens of a three-electron- beam gun. CONSTITUTION:An auxiliary electrode 53, which has an opening 531 surrounding electron-beam passing holes 41R, 41G and 41B, is placed between a third grid electrode 47 and a fourth grid electrode 48, which constitute the main lens of a three-electron-beam gun. The auxiliary electrode 53 and the third grid electrode 47 are made to have the same electric potential. The degree of the concentration of the three electron beams is controlled by changing the distance X between the electrodes 53 and 47, as well as the thickness of the electrode 53. By the means mentioned above, since the degree of the concentration can be controlled only by altering the form of the electrode 53, the most suitable concentration can be realized by using the same electron gun irrespective of the size of a cathode-ray tube.

Title: Manufacture of ceramic chip carrier
Inventor: NAKAMURA YOSHIFUMI
IPC: H01L23/12
Filed: 1992-03-05
Abstract: PURPOSE:To prevent shortcircuit with ant adjacent through-hole and to divide a ceramic substrate without pulling a conductor to one side to cause breakage at a through-hole part or without generating cracks by applying cupric oxide paste of low viscosity whose volume is larger than that of copper to a through- hole which becomes a side electrode. CONSTITUTION:A green sheet wherein conductor print and via burying are carried out is thermo-compressed and laminated to form a through-hole. It is notched to connect each through-hole if necessary. Cupric oxide-based conductor paste is printed on the inner wall of a through-hole to form a conductor layer 35A. A lamination wherein print is performed is unbound and burnt in nitrogen atmosphere. A scribe line 41 is formed on a through-hole of the burnt substrate and the substrate is divided into pieces. Since cupric oxide paste applied to a through-hole is deoxidized and becomes a thin conductor film after burnt, a ceramic substrate can be divided into pieces without generating cracks, etc.

Title: Semiconductor laser excited solid-state laser
Inventor: YAMAGUCHI SATORU
IPC: H01S3/094
Filed: 1989-03-02
Abstract: PURPOSE:To provide a solid-state laser being small-sized, having a high efficiency and capable of providing beams of high quality by using an optical coupling device consisting of two distributed index lenses arranged in series and having a focus commonly with each other for collecting semiconductor laser output to optically pump the solid-state laser element. CONSTITUTION:Oscillation light from a semiconductor laser 1 as a light source is collected by a first distributed index lens 2a which converts the light into parallel beams. A second distributed index lens 2b arranged so as to have a focus commonly (to be cofocal) with the first distributed index lens 2a converges the beams to make a beam spot within a solid-state laser element 3 whereby the laser element 3 is pumped optically. A constant size of real image can be obtained regardless of variation of a distance between the light source and the first distributed index lens. Since the distributed index lenses 2a and 2b are arranged cofocally, beam spots (10a, 10b) can be converged into constant sizes regardless of variation of distance from the semiconductor laser chip (arranged at 9a) to the first distributed index lens (from 9a to 9b).

Abstract: PURPOSE: To produce a getter agent which adsorbs org. gases well and does not cause scattering of powder by coating the other surface except one surface of a plate-like alumina molding with water glass and firing the same.  
     CONSTITUTION: Bayer's aluminum hydroxide or the like consisting essentially of Al 2 O 3 , SiO 2 , etc. is molded to form an alumina molding 1. Thence, the other surface except the surface 1a functioning as a getter out of the surfaces of said molding 1 is coated with a water glass layer 2 and is fired at about 400W 700°C, whereby a getter agent 3 is formed. An adhesive 4 is coated on the outer side of the water glass later 2 for adhering and fixing the getter agent 3. Hence, the percolation of the adhesive 4 into the alumina material 1 and the degradation of the getter function are obviated. When the getter agent 3 is used by adhering and fixing the same to a required place of a switch, a relay, etc., the production of the powder is prevented by the layer 2 and the degradation in the function of the switch, the relay, etc. is prevented.

Title: Blade installation structure of turbo-machinery
Inventor: SAKATA SHIYOUJI
IPC: F01D5/30
Filed: 1982-03-29
Abstract: PURPOSE:To prevent a hair crack caused by fretting from growing into a large crack by separating the fretting occurring point from any high stress ocurring point in a blade fixing groove. CONSTITUTION:A blade fixing groove 6 consists of a bearing surface 6a that bears centrifugal force, an ''R'' (a rounded corner) of a groove corner part 6b, and a bottom surface part 6c. The ''R'' of the groove corner part 6b is formed in such a manner that it meets with the bearing surface 6a at right angles. Since the surface pressure acting on the bearing surface 6a acts perpendicularly to the surface 6a, compressive stress due to surface pressure is induced at point b or b' and no tensile stress occurs so that the growth of a crack can be prevented.

The alloy is then subjected to compressive working divided into a plurality of times through a state with plastic working stopped in the axial direction. At this time, after applying a positive plastic macro-strain in one specified direction, a negative plastic strain is applied in the same direction in a plurality of times so that the compression up to ≥-0.1 logarithmic strain is necessarily made free. As a result, the residual flux density can be increased by about 0.2kg as compared to continuous compressive working equal to this working method in the total quantity of compressive strains.

Abstract: PURPOSE:To reduce visual deterioration of a pattern form of an original image by a method wherein the forming position of a recording head is shifted by several dots in the main scan direction and sub scan direction, and recording is performed so that the superimposed state of different colored recording dots varies discretely and two-dimensionally. CONSTITUTION:An original image position x of a recording dot on a main scan line is expressed by a square cell mark, and its address is x1-y1, x2-y1, x3-y1 to x11-y1. Since a shift quantity of a main scan line at this subscan position y1 is one dot left centering an axial line yc following a pattern sy1, all data on the main scan line are at first shifted left by one dot. Then, shift in the sub scan direction of the shifted recording dot on the main scan line is performed following a pattern sx1. The xo-th recording dot is not shifted since it is on an axial line xc of the pattern. X1 is shifted upward by one dot and x2 is shifted downward by one dot. Then, x3 is not shifted. Dot shifting in the sub scan direction is performed thus following the pattern sx1.
