Title: Electronic part transfer head
Inventor: ABE SHIGETAKA
IPC: H05K13/04
Filed: 1992-02-17
Abstract: PURPOSE:To mount all the leads on solder without irregular pressing by providing a tip part having an attraction hole as a nozzle for attracting an electronic part and by providing the tip part movably while communicating it with a suction hole of a nozzle shaft. CONSTITUTION:A suction hole 7a of a mount part 7 and a suction hole 8a of a tip part 8 are communicated with a suction hole 1a of a nozzle shaft 1. When vacuum pressure is not applied, the tip part 8 is held not to drop by a projection 13. When vacuum pressure is applied and an electronic part 14 is attracted, the tip part 8 is sucked up and a spherical projection part 10 and a recessed part 11 of the mount part 7 come into contact with each other. A transfer head attracting the electronic part 14 attains above a substrate 16 and descends to land a lead 15 on paste solder 17 on a substrate 16. When the substrate 16 is aslant to a lower edge face of a lead of the electronic part 14, the tip part 8 slides with a suction hole communicated; thereby, the electronic part 14 slants along the slant of the substrate 16 and lands a number of leads 15 on the paste solder 17 to be pressed by uniform force.

Abstract: PURPOSE:To suppress the number of parts to be increased by inputting an address to the memory cell of one group as it is and inputting an address passed through one address selector to the memory cell of the other group. CONSTITUTION:Out of the address signals of (m+1+n) bits, the address signal of the high-order (m) bits is inputted to a memory cell 5b of the 2<n> pieces of groups 1 as it is, and the address signal of (m) bits is inputted from an address selector 3 to a memory cell 5b of the 2<n> pieces of groups 0.

Title: Temperature correcting device for optical refractive index measuring instrument
Inventor: KIMURA SHIGERU
IPC: G01N21/41
Filed: 1988-02-15
Abstract: PURPOSE:To shorten a measurement time and to simplify the circuit constitution by adjusting the output value of a temperature detecting element to the same variation component as the variation component of the output value of a sensor with time and detecting a refractive index from the difference between the output value of the temperature detecting element and the output of the sensor. CONSTITUTION:The light emitted by an LED (light emitting diode) 6 passes through liquid 10 to be measured and is refracted by the surface of a prism 7 and detected by a sensor 2. Then the refracting index of the liquid 10 is detected from the output of the sensor 2. At this time, a temperature correction is made at the same time according to the detected temperature of a thermistor 1. The output of the sensor 2 is processed by current-voltage conversion 4 to obtain a sensor output voltage E and the output of the thermistor 1 is processed by resistance-voltage conversion 3 to obtain a thermistor output voltage F, but an adjustment is so made at this time as to obtain the same variation component as the variation of the sensor 2 with time. The difference between those voltages E and F is calculated by an operational amplifying circuit 5, which outputs a sensor output voltage G after the temperature correction.
