Title: Method of chemically metal coating bad-electroconductive supporter comprising inorganic material
Inventor: BOGENSCHUETZ AUGUST F
IPC: H05K3/38
Filed: 1986-07-02
Abstract: Process for chemically metallizing an inorganic substrate, which is a poor conductor of electricity, e.g. a ceramic material or glass. The surface of the substrate is chemically activated so that chemical bonds are more readily formed with a subsequently applied, inorganic adhesion promoter. The adhesion promoter in turn facilitates chemical bonding with a subseqently applied metal layer, e.g. a copper layer, which is applied by a wet chemical method. The activation step and the step of applying an adhesion promoter, in combination with at least one thermal treatment, results in an adhesive strength between the metal layer and the substrate surface which equals or exceeds the adhesion strength of the surface of the substrate material.

Title: Method of correcting nonuniformity of thermally printed paper surface whole region
Inventor: ANSONII RICHIYAADO RABINSUKII
IPC: B41J2/36
Filed: 1989-06-16
Abstract: PURPOSE: To eliminate nonuniformity in a print density across a space and thereby to attain uniformity by determining the number of pulses to be applied to a thermal print head by a prescribed arithmetic processing on the basis of a correction factor determined from the average of the number of heat pulses being applied, the number of print lines and the number of pulses corresponding to an image density to be printed on the lines. CONSTITUTION: An image to be printed is represented by a matrix 20 composed of density pixels arranged in rows and colunms. In regard to each density element, the uncorrected number N of pulses is obtained from an input density value expressed by D by using a correspondence table 32 incorporated in a computer 30. The uncorrected number of pulses thus obtained is recorded in a pulse matrix 34 so that an Ltotal row of the number Ni L of pulses be given. An average value N is taken out from the matrix of this number and the number of this value is inputted to a correspondence table 38. A prescribed correction factor A, the total number LT of lines and the number L of lines being inputted, a correction algorithm calculates the corrected number of pulses.  The uncorrected number N of pulses is coupled with the corrected pulses for each correction algorithm in a coupling block 36 and thereby the corrected number Ni L of pulses is given.

Title: Hysteresis circuit
Inventor: OKAWA SHINKEN
IPC: H03K3/353
Filed: 1984-07-25
Abstract: PURPOSE:To set freely a logical threshold volage level by using an inverter consisting of two pairs of MOSFETs to form a hysteresis circuit. CONSTITUTION:A part consisting of FETTp1, Tp2, Tn1 and Tn2 is equivalent to a complementary MOS inverter A. For the input/output characteristics of the inverter A, about half of the input H-level voltage is equal to the logical threshold voltage (broken line) as long as the ON resistance of an FET at the p channel side is equal to the ON resistance of an FET at the n channel side. Then the logical threshold voltage is shifted toward H as shown by a solid line in case the ON resistance of the n channel side is larger than that of the p channel side. Then the logical threshold voltage is shifted toward L as shown by a 1-dot chain line if the ON resistance of the p channel side is larger than that of the n channel side. Thus a logical threshold voltage lvel can be freely set.

Title: Method for forming coat
Inventor: AOKI MOTOHISA
IPC: B05D1/40
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To prevent a spiral mark, the marring of a lower layer and the generation of a bubble in the process to smooth a coat by rubbing from appearing and thereby, enable the formation of the coat with a smooth and uniform surface by providing a curved face with a specified curvature in a direction in which a smoothing member runs and an orthogonal direction with the described direction. SOLUTION: A coating liquid discharged to an object 1 to be coated generates a pool on the peripheral edge of a contact point in a smoothing member 20. However, the coating liquid finding its way into the downstream side of the contact point in the pool by the discharge of the coating liquid moves to the object 1 side to be separated from the pool and entrain the object 1, because a gap between the smoothing member 20 and the object 1 becomes wider by the curvature of the smoothing member 20 and the curvature of the object 1, resulting in the deterioration of a liquid retaining force under the effects of surface tension. Thus, the coating liquid settles on the object 1.  In this case, the coating liquid advancing to the peripheral edge of the pool shows a deteriorated liquid retaining force and entrains the object 1 even on both sides of the smoothing member 20, i.e., on both sides in the axial direction of the object 1 as the gap between the smoothing member 20 and the object 1 becomes wider on account of the curvature of the smoothing member 20.

Filed: 1989-06-16
Abstract: PURPOSE:To reduce the number of component parts of a substrate transfer device by constituting it in such a way that reciprocal and up and down movement of a substrate feed member is done by the same drive source. CONSTITUTION:After a rotary solenoid 52 is operated and the regulation by a substrate stop lever 51 is reset, a drive motor 24 is driven, and a feed member 21 is fed via a linear drive bearing 28. At this time, the feed number 21 is lowered to the position where feed bars 22, 23 become roughly horizontal together with the movement of the linear drive bearing 28, and feed claws 26, 27 come in contact with a substrate. Thus, a substrate on a supply conveyor 1 is fed onto a work table 18 by the feed claw 26, and the substrate on the work table 18 is fed onto a discharge conveyor 20 by the feed claw 27. When completion of the feed of the substrate by the feed member 21 is detected by a balance weight 45 through reflection of light of an optical sensor 47, the movement of the drive motor 24 is stopped and the feed of the feed member 21 is completed.

Filed: 1990-06-15
Abstract: PURPOSE:To purify water such as polluted water or sludge in low cost and to efficiently solidify a solid substance by adding a size having a carboxyl group and a salt containing a metal ion substituted with H of the carboxyl group to polluted water under stirring. CONSTITUTION:Sludge recovered from rivers is received in a stirring container and, for example, CMC having a carboxyl group and a salt containing a metal ion (e.g., calcium chloride) are added to said sludge to be mixed therewith under stirring. Concretely, when sludge (muddy water) W is introduced into a stirring tank in such a state that the opening and closing valve 2A of a sludge dehydrating apparatus 1 is closed and a stirrer 4 is operated, the sludge W is stirred. Therefore, a size and a slat are charged in the stirring tank 2 to carry out stirring for 5min. The water falling in a dehydrating cylinder 3 flows out of water passing holes 3B... to be recovered by a receiving tray 5. When a screw conveyor 6 is driven by operating a driver 6A, a settled solid is pushed toward a discharge port 3C and pressure gradually becomes high in a taper part 3A and, therefore, the settled solid is dehydrated to be discharged from the discharge port 3C.
