摘要： PROBLEM TO BE SOLVED: To provide a method by which the conventional step of exchanging masks in accordance with the dimensional rank of a singulated substrate can be eliminated, because the dimensional classification of the singulated substrates becomes unnecessary, and, at the same time, an inexpensive fine resistor can be manufactured easily. SOLUTION: This method of manufacturing resistor includes a step of forming a first resist layer 27 on the upper surface of a sheet-like insulating substrate 21 so as to cover protective layers 24 and 26 and, at the same time, a second resist layer 28 on the rear surface of the substrate 21, and a step of forming a plurality of slit-like first split sections 29 for dividing the substrate 21 into a plurality of strip-like substrates by separating a plurality of pairs of upper-surface electrode layers 22. This method also includes a step of forming a plurality of pairs of side-face electrode layers 30 on the internal surfaces of the first split sections 29 by electroless plating the insulating substrate 21 containing the split sections 29 with nickel, and a step of patterning the side-face electrode layers 30 by peeling the first and second resistor layers 27 and 28 from the substrate 21.

摘要： PROBLEM TO BE SOLVED: To realize more accurate measurement for resistance value at the time of grooving on a resistor film, by measuring the resistance value by a fourcontact method using a lead chuck holding a lead wire as contacts, and causing the timing for holding the lead wire to be earlier than the timing for holding the film resistor. SOLUTION: A glass chuck 1 and a chuck holder 6 hold and continuously connect grooves 16 and 16a, respectively, through which a lead wire 32 of a film resistor 31 is led in and out, and the inside of the distal end at one end is tapered. A lead chuck 4 is fixed on an insulating plate 5, mounted on the chuck holder 6 with a fulcrum pin 9, and the distal end thereof has a through- hole 17, thus holding the lead wire 32. A pair of contacts on the lead chuck 4 are electrically insulated from each other and connected independently with cables 14. An insulator sleeve 12 is connected with the chuck holder 6. In addition, an arm 10 turns the lead chuck 4 by the movement of a dog 11 driven by an opening lever 22, fitted from outside of a shaft 13 for driving rotation and linear movement.

摘要： PURPOSE:To obtain a thin paint layer of a definite shape by a method wherein a tip nozzle port is formed to be flat and a paint of a definite amount is discharged to the surface of an electronic component directly from the upper part when the electronic component transferred at definite intervals and the nozzle port are crossed. CONSTITUTION:A transfer means 1 transfers many resistance components R at definite intervals; one pair of handdling tapes 3 are transferred horizontally in one direction by using a plurality of carrier rollers 2 which have been arranged so as to be faced in accordance with a length between both lead wires (f). One pair of positioning disks 4 which have been arranged and installed at the inside of the tapes 3 are shaft-supported by using a common horizontal shaft. A paint container 8 is attached in a state that a nozzle 9 is tilted from the bottom toward the oblique lower part; a paint P of a definite amount each is supplied from a tip nozzle port 9a of the nozzle 9. The nozzle port 9a is formed to be flat so as to match a painting shape to the surface of the resistors R. Thereby, a thin paint layer of a definite shape can be formed.

摘要： PURPOSE:To communicate a message at the prescribed time and to recognize a person located at a remote location by providing a receiver receiving a signal from a transmitter, connecting a directional antenna to a receiver, driving the antenna in every direction, measuring the direction of location of the transmitter and the strength of a radio wave and converting the distance. CONSTITUTION:An antenna 6 is driven by a motor 7 in every direction and the direction directed by the antenna is stored by a control section 9. A radio wave with a prescribed frequency sent by a transmitter is received via the antenna 6 by a receiver 8 and the receiver 8 measured the strength of the radio wave. The distance between the transmitter and the receiver is converted from the strength of the radio wave at the strongest intensity to recognize the distance and the direction of the transmitter is recognized from the direction of the antenna stored by the control section 9 and the result is displayed on a display device 10. Thus, a person carrying the transmitter and visiting to somewhere can listen to the message stored at the routine time and the person carrying the receiver can recognize the location of the opposite party at that time.
