IPC: B41N3/08
Filed: 1990-11-30
Abstract: PURPOSE:To obtain an additive for dampening water, in which an organic solvent, to which an organic rule is applied, need not be used completely, and to acquire dampening water getting no trouble on printing aptitude by containing the additive for dampening water in dampening water only by a proper quantity by containing at least one kind of specific lactic acid ester. CONSTITUTION:An additive for lithographic dampening water containing at least one kind of lactic acid ester, in which R in formula CH3CHOHCOOR represents a methyl group, an ethyl group, an isopropyl group or a butyl group, is manufactured, and an acid or salts, a water-soluble high molecular compound, a chelating agent, etc., may be comprised in the additive for dampening water. Since methyl lactate and ethyl lactate in said lactic acid ester are compatibilized with water at arbitrary ratios, they may be comprised in the additive for dampening water at any ratio.

IPC: H04N5/32
Filed: 1992-12-16
Abstract: PURPOSE:To provide the thin and compact planar image pickup device reducing distortion over a wide area by simultaneously scanning the plural divided areas of an image pickup plane while using a planar electronic source. CONSTITUTION:Electrons generated by plural fillament-shaped thermal cathodes 2 horizontally arranged at equal intervals are divided by vertical scanning electrodes 4, which are vertically separated into a certain number corresponding to the number of horizontal scanning lines by an electric field impressed between a back electrode 1 and a grid electrode 3, corresponding to vertical scanning lines. Next, the electrons are horizontally deflected by a horizontal deflecting electrode 6 equally to the width of a transparent electrode 9 and converted to image signals by a photoelectric convertion film 10 later.

Title: Solenoid valve
Inventor: WADA TOSHIYUKI
IPC: F16K31/06
Filed: 1995-11-29
Abstract: PROBLEM TO BE SOLVED: To prevent contaminant such as dust and iron powder of the outside from entering by arranging communicating passages in parallel with the center axis of a plunger on the outer circumferential face of a valve, without providing a discharge hole in a fixed iron core. SOLUTION: When current flows in an exciting coil 18, a fixed iron core 14 is excited so as to attract a plunger 13 toward the fixed iron core 14 against a spring 16. When the exciting coil 18 is de-energized, the plunger 13 is released from the fixed iron core 14, and the plunger 13 is pushed forward by the spring 16. In this way, an input port 21 is opened or closed with the extreme end part of the plunger 13 in response to energization or de-energization of the exciting coil 18. For preventing invasion of contaminant from the outside, the fixed iron core 14 is not provided with a discharge hole, control fluid stayed in the center part of the plunger 13 is discharged to an output port 22 part through communicating passages 23A formed on a valve 23 part. The communicating passage 23A can perform sufficient discharge because of the short flow passage length.

Inventor: KOBAYASHI TAKASHI
IPC: H05K3/28
Filed: 1989-12-25
Abstract: PURPOSE:To obtain a low cost and high reliability thick film multilayer interconnection device by a method wherein, after a lower layer wiring part is formed on an insulating board, a green sheet is applied and pressed and glass paste is applied to the surface and the whole laminated unit is baked. CONSTITUTION:A lower layer conductor 12 is formed on a board 11 and a green sheet 13 having a through-hole for connecting an upper layer conductor 15 to the lower layer conductor 12 is pressed against the board 11 and the lower layer conductor 12. Further, an overcoat glass layer 14 is printed on the surface and the whole laminated unit is dried and baked. After one baking process, the upper layer conductor 15 is formed. A long as a green sheet is employed, crackings 17 are produced in step parts. However, the glass component of the overcoat glass layer 14 penetrates into the crackings 17 and an electric short-circuit between the lower layer conductor 12 and the upper layer conductor 15 can be avoided by the overcoat glass layer 14 itself. With this constitution, only one baking process is sufficient and a low cost thick film multilayer interconnection device can be obtained and, further, a dielectric breakdown caused by microcrackings can be also avoided.

Title: Method and device for judgment of ream weight of medium
Inventor: SAWADA TAKETOSHI
IPC: G01B11/06
Filed: 1993-12-28
Abstract: PURPOSE:To accurately judge a ream weight of a medium by a method wherein a light is emitted on the medium such as a paper and an amount of the light that penetrated the medium is detected to be compared with a prescribed value indicating a ream weight (a thickness) of the medium to be measured and an amount of the emission light is rendered constant, thereby judging the ream weight. CONSTITUTION:A control section 3 can execute two action modes to judge a ream weight. That is, when a thickness of a medium 6 to be measured is less than a prescribed value C, an amount of an emission light of a light-emission section 1 is maintained constant and an amount of a reception light of a photodetector section 4 is detected. The amount of the reception light is compared with a threshold value stored in a table 3c (it is a boundary value by which it is judged whether the medium 6 is one-ply or multi-ply one in respect to each ream weight.), thereby detecting the ream weight of the medium 6. In the case where the medium 6 has a greater thickness, when the thickness exceeds the prescribed value C, the control section executes the other action mode so that the detection of the ream weight is carried out by adjusting the amount of the emission light so as to equalize the amount of the reception light. At that time, a table 3d wherein both of the threshold values obtained based on the amounts of emission lights in terms of one-ply and multi-ply medium are stored, is referenced in order to equalize the amount of the reception light.
