Title: Manufacture of through-hole circuit board
Inventor: HASHIMOTO TETSUYA
IPC: H05K3/40
Filed: 1987-10-20
Abstract: PURPOSE:To enhance through-hole conduction yield and to improve workability drilling a hole which penetrates the insulation layer from both sides in a laminated body forming a film where conductive layer is coated at least at one side and by hardening conductive materials by filling conductive materials from the direction where the hole was drilled. CONSTITUTION:A film 4 where a conductive layer 3 is coated on at least one surface of a laminated body 1 where conductive layers 3 and 3' are laminated at both sides of an insulation layer 3 is formed. Then, a hole 5 for through-hole is drilled at the laminated body 1 where the film 4 is formed and a conductive material 6 is filled into the hole 5. Any substance which is superb in wetting properties with the conductive layers 3 and 3' and is connected to them electrically after curing by post-process can be the conductive substance 6 which includes for example solder paste and conductive adhesive. Then, conductive adhesives are cured at room temperature, by heating, or by irradiation of ultraviolet rays, while solder paste is pre-heated as needed, is subject to reflow, and then to cooling hardening.

IPC: B41M5/155
Filed: 1986-11-05
Abstract: PURPOSE:To enhance color forming properties, raw preservability and stability of developed color images, by providing a color forming recording layer comprising an electron-donative colorless dye and an electron acceptive compound of a specified formula on a base to produce a recording material. CONSTITUTION:An electron donative colorless dye and an electronacceptive compound of formula I (wherein R1 is hydrogen or an alkyl, R2 is a bivalent group, and Ar is an aromatic ring) are added to an aqueous solution containing about 0.25-10% of a water-soluble high molecular weight material, followed by dispersing by agitating in a ball mill or the like to prepare a coating liquid. The weight ratio of the colorless dye to the electron acceptive compound used is preferably 1:10-1:0.1. The coating liquid is applied to a base such as a raw paper, a woodfree paper and a synthetic paper to provide a color forming recording layer, thereby obtaining a recording material. The coating weight of the coating liquid is generally about 2-10 g/m<2> as solid components.

Title: Picture input device
Inventor: IWATA SHIYOUTAROU
IPC: B25J19/04
Filed: 1987-10-19
Abstract: PURPOSE:To improve positioning accuracy and to expand a picture to an effective field by using a mirror unit having a function for inputting a picture in two recognizing areas selectively to a TV camera. CONSTITUTION:When a rotary mirror 3a is turned to the side of a reflecting mirror 4a, a picture inputted from one recognizing area 6a to the mirror unit 5 is reflected by the mirror 3a, inputted to the TV camera and detected as a picture. When the mirror 3a is turned to the side of a reflecting mirror 4b, a picture inputted from the other recognizing area 6b to the mirror unit 5 is reflected by the mirror 3a, inputted to the TV camera 1 and detected on a screen. Since the screens are selectively detected as individual both sides, the same effective field as a case using no mirror unit 5 can be obtained at the same scale, and since a long distance between respective recognizing areas can be obtained similarly to an ordinary method, positioning accuracy can be improved.

Title: Image forming device with paper refeeding means
Inventor: MURAMATSU HIDEO
IPC: G03G15/00
Filed: 1987-10-19
Abstract: PURPOSE:To prevent the occurrence of jam by prohibiting the next manual paper feeding until the end of forming a second image at the time of carrying out manual paper feeding under a paper refeeding mode and when a sheet of paper is positioned on a prescribed position of a paper refeeding tray. CONSTITUTION:At the time of a paper refeeding mode, midway while a sheet of paper which is manually fed by a manual paper feeding means and on which the first image is formed by an image forming part is being sent to a paper refeeding unit 103 by means of invertingly conveying rollers 56, 57, as its front end is detected by a sensor, a back restricting board 65 which is on standby in the position of a B5-size shorter side is moved in the g' direction after a defined timer time and then, is stopped as the rear end is detected by the sensor. Then, side restricting boards 62, 63 are mutually approachingly moved and, as sensors 381, 382 are brought into contact with the sheet of paper, they are stopped to carry out positioning. Then, by driving a paper refeeding roller 38, the sheet of paper is sent to the picture forming part to form the second image and, during this time, manual feeding by a manual paper feeding means is prohibited. After the second image is formed, as the restricting boards 62, 63, 65 are returned to their original positions, it becomes possible to carry out the next manual feeding. Thereby, the occurrence of jam can be prevented.

Title: Fluid actuator
Inventor: SNITGEN JOSEPH D
IPC: F15B11/032
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To combine load applied by a primary cylinder with load applied by a secondary cylinder by incorporating a specified valve device for controlling a fluid flow between two cylinders. SOLUTION: A pressure fluid in an accumulator 20 is supplied through a fluid coupling 30, a filter 34 and a regulator 36 to a control valve 52 by the operation of an on/off switch 32. When the control valve 52 is put in the illustrated position, the pressure fluid is supplied to solenoids 42, 50 to put valves 40, 46 in the illustrated postitions. The valve 46 forces pressure fluid to flow through a port 78 into the right part of a chamber 72 of a cylinder 16, thereby elastically pressing a piston 82 to the left and releasing the fluid in the left side of a chamber 92 of a cylinder 18 through a valve 46 to the atmosphere.  A solenoid valve 42 puts a valve 40 in the illustrated position, thereby transferring the pressure fluid in the left of the piston 82 from the chamber 72 to the right of the chamber 92, whereby load applied by piston rods 116 and 122 is increased to intensify the pressure.

Title: Electroplating method
Inventor: OTSUKA KAZUHISA
IPC: H05K3/18
Filed: 1992-10-01
Abstract: PURPOSE:To enable the easy setting of the plating film thicknesses of respective surfaces without the insertion of shielding plates and without the change of the construction of the plating cell itself by separately controlling the currents flowing to a material to be plated from anodes facing the respective surfaces discretely with the respective surfaces. CONSTITUTION:The deposited film thickness of plating is known to be nearly proportional to the quantity of electricity and the current values from the anodes facing the respective surfaces are controlled by constant current power sources 6, 7, by which the deposited film thicknesses of the respective surfaces are easily set. The plating film thicknesses of both surfaces are nearly equaled by passing the currents proportional to the plating areas of the respective surfaces from the anodes facing the respective surfaces in the case of execution of patterned electroplating on, for example, a printed circuit board varying in the plating areas of both surfaces. The plating at different thicknesses on both sides is easily obtd. by setting the current values from the anodes facing the respective surfaces at a desired plating film thickness ratio if the plating varying in the film thicknesses of both surfaces is desired.

Title: Knock detector for internal combustion engine
Inventor: YAMADA JUNJI
IPC: F02D45/00
Filed: 1990-10-03
Abstract: PURPOSE:To obviate any filter and miniaturize the knock detector by letting a peak hold circuit have a low-pass filter function, setting cur frequency to the upper limit value of knock frequency. CONSTITUTION:An interface circuit is inserted into space between knock sensor and an analog-to-digital converter 3, and it is composed of a peak hold circuit 26, an amplifier 27 and a gain controller 28. Here a condenser C1 in the peak hold circuit 26 outputs a peak level while it resonates with a resistor RF, fulfilling a low-pass filter function. In brief, cut frequency of a low-pass filter can be set to the upper limit value of knock frequency. With this constitution, since it is unnecessary to install any filter there, a knock detector can be thus miniaturized.
