Title: Anisotropically conductive joint member
Inventor: KOBAYASHI KOJI
IPC: H05K1/14
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of migration at the joint of, e.g. a display panel made from an Ag or Al electrode by incorporating a specified amount of an organic or inorganic ion exchanger into an insulating adhesive containing conductive particles. SOLUTION: Conductive particles in an amount of at most 15vol.% are added to an insulating adhesive containing, e.g. an epoxy resin and a curing agent for epoxy resin to give an adhesive composition. This composition is compounded with 0.02-25wt.% organic cation exchanger represented by, e.g. the formula R.SO3 H or RCOOH, organic anion exchanger represented by, e.g. the formula R.NCl, R.N, R.NH, or R.NH2 (wherein R is a hydrocarbon group), or inorganic ion exchanger comprising, e.g. green sand, synthetic zeolite, or permutite, having a mean particle diameter of at most 3μm. The ion exchanger is mixed with a solvent and subjected to ultrasonic dispersion or dispersed by a homogenizer to prevent agglomeration. The dispersion is mixed with a resin solution before use.  The ion exchanger will incorporate metal ions dissolving out from an electrode when an electric current flows so that the occurrence of migration is prevented.

Title: Film unit with lens
Inventor: IMAMURA TAKASHI
IPC: G03B15/03
Filed: 1997-03-03
Abstract: PROBLEM TO BE SOLVED: To prevent a user from receiving electric shock in a stroboscope device by the infiltration of an electrolyte soln. such as sea water by subjecting the outer surface of a metal conductive member which connects the circuit board of a stroboscope circuit to the terminal of a stroboscopic tube to insulation treatment. SOLUTION: The whole body of a conductive plate 60 which electrically connects one electrode of a stroboscopic tube to the pattern of a circuit board consists of a copper plate produced by folding and having good conductivity. The one end 60a is soldered to one electrode of the stroboscopic tube, while the outer end 60b is soldered to the part on a circuit board to be connected to the main capacitor on the circuit board. Most of the conductive plate 60 except for the ends 60a, 60b is subjected to insulation treatment to form an insulating part 60c on the outer surface. Thereby, even when an electrolyte soln. such as sea water infiltrates into the joints between the front cover and the back cover of the unit, the user can be prevented from receiving electric shock by a high voltage current stored in the main capacitor and the short circuit thereby can be prevented.

Title: Semiconductor radiation detector
Inventor: SATO KEIJI
IPC: G01J1/02
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To make it possible to detect radioactive rays in different energy bands, by perpendicularly projecting radioactive rays into the impurity region of a first conductivity type on a silicon semiconductor substrate of second conductivity type, and detecting the signals thus obtained on a semiconductor substrate-by-semiconductor substrate basis. SOLUTION: A large number of PIN diodes 1 are laminated with spacers 2 made of insulator in-between. Radioactive rays are perpendicularly projected into the larger face, that is, the ordinary light receiving face, of the PIN diodes 1 where a p<+> -type impurity region is formed. From this it follows that the PIN diodes 1 in the lower layers detect radioactive rays of high energy that has penetrated the upper layers. The intensity of radioactive rays in high energy bands is relatively higher at the lower layers. Thus the signals of the PIN diode 1 element that are generated by radioactive rays' being incident upon the PIN diodes, are independently input to a pre-amplifier through a capacitor, and reverse voltage is applied on the cathode side in common.

Title: Counter circuit
Inventor: ARAI SEIJI
IPC: H03K23/40
Filed: 1989-02-27
Abstract: PURPOSE:To attain high speed calculation even in the case of the occurrence of multi-bit by dividing high-order and low-order bits of the result of address increment, detecting the occurrence of carry at the low-order bit and informing the result to the high-order bit. CONSTITUTION:Let the increment of an address be 1, the level of a control signal C1 goes to 1 and a transistor(TR) 43 of an AND circuit stacked laterally using the low-order 16-bit of the address as FFFEH is turned on. Then, the outputs of an AND gate 67 and an OR gate 70 are logic '0', carry input circuit 23 is not turned on and no carry is outputted. When the address is incremented to be FFFFH, TRs of the AND circuit are all turned off and the output goes to logic '1'. Since the signal C1 and the gates 67, 70 are logic '1', the circuit 23 is turned on and a carry is outputted. Thus, the low-order bit detects the occurrence of the carry, and informs it to the high-order bit to attain high speed calculation.

Abstract: PURPOSE:To aim at the promotion of shortening in a car braking distance while keeping off a wheel lock, by judging the height of a friction factor mu of a road surface on which a car is running and thereby changing the setting value that determines the generating timing of a decompression signal. CONSTITUTION:Setting values (a differential velocity DELTAV for setting a simulated velocity V, a maximum tilt angle theta1 capable of taking the simulated velocity V and a slip ratio S1) for low friction factor mu road use are stored in a memory 14 in advance, and in time of braking, the simulated velocity V is calculated from wheel velocity Vw by a wheel velocity detector 11 at an operational part 13 on the basis of these setting values. Next, a velocity Von making a decompression signal for an actuator 15 used for braking fluid pressure control turn to ON with the tilt angle is determined. Then, a low peak velocity Vlp is found out of the acceleration of the wheel velocity Vw, and when this Vw comes to a valve off velocity Voff, the decompression signal is made to turn OFF. In addition, that whether a difference between Von and Vlp is smaller than a fixed value A or not is judged, and when small is the case, it is judged to be a high friction factor mu road so that the setting value is changed to that for high friction factor mu road use.

Title: Sizing of very fine metal wire
Inventor: SOGA KAZUYA
IPC: B21C1/00
Filed: 1988-02-29
Abstract: PURPOSE:To make it possible to prevent a very fine metal wire from discoloring and suffering reduction in bindability and adhesion during sizing, by cold- drawing a nickel-plated wire of a specified diameter without using any lubricating oil and sizing it. CONSTITUTION:A very fine wire plated with nickel (nickel alloy) of a diameter of 0.01-0.5mm is cold-drawn and sized. According to this process, the final drawing can be performed without using any lubricating oil; therefore, no oil remains on the surface of the very fine wire so that its discoloration due to the presence of oil can be improved. Since the final drawing is performed after the wire is plated with nickel, a lubricating action resulting from the plating can be attained, the life of a drawing die can be retained to an extent substantially equivalent to that in the case in which cold drawing is performed by using a lubricating oil. Since the sizing is performed after the wire is plated with nickel, the wire can be prevented from rusting even when the sizing agent is a water-soluble one.
