Abstract: PROBLEM TO BE SOLVED: To perform the alignment of an LSI and a probe accurately for accurate probing to a miniaturized LSI electrode such as an area bump in the electric inspection of the LSI by an LSI tester. SOLUTION: An LSI 13, which is picked up from a tray part, is carried to a positioning stage part 2 by a handler part 9 at first.

Filed: 1991-10-22
Abstract: PURPOSE:To suppress a temperature rising of a cold storage chamber by operating a blower for a predetermined period after a door of the chamber is opened or closed. CONSTITUTION:When a compressor 12 is stopped, the air of a cold storage chamber raised at its temperature upon outputting and inputting of refrigerated food is returned to a cooler by the operation of a blower 9, and then discharged to a freezing chamber, the storage chamber. Since the compressor 12 is stopped, the air which passes the cooler is not almost heat exchanged to be an ambient temperature state. When the air of the ambient temperature is fed to the freezing chamber, a thermistor temperature sensor 26 mounted in the freezing chamber senses a high temperature to operate the compressor 12, to cool the cooler and to supply chilled gas to the storage chamber. Thus, a temperature rising of the storage chamber can be suppressed.

Title: Network communication system
Inventor: AKAO TAKASHI
Filed: 1984-12-28
Abstract: PURPOSE:To improve the efficiency of expansion by transmitting the data of the last terminal unit to the intermediate and the first stations by a manner that the right-side switch of the intermediate unit is converted in the receiving status and left-side switch of the last unit is in transmitting status. CONSTITUTION:The system consists of the n-pieces of terminal units TE1, TE2,...TEn which are loop-connected. All the units less the first one TE1 are of identical constitution. the difference between the first unit TE1 and the rest is that the former does not have the left-side switch. Of the unit TE2, the left- side switch SWL2 is connected to the input-side coupling transistor T<2>1, and the right-side switch SWR2 is to the output-side coupling transistor T<2>0. Between these two transistors T<2>1 and T<2>0, a receiving circuit RV2, a reception processing circuit RC2, a transmission processing circuit SC2, and a driving circuit DR2 are connected. Accordingly, any dedicated transmission line is not necessary between the first and the last terminal units. Additionally, in case of expansion of the system, what is needed is only to connect another unit to the last one, and therefore the expansion work becomes of improved efficiency.
