Title: Resin mold deflashing apparatus for electronic device
Inventor: FUSE YOJIN
IPC: H01L21/56
Filed: 1990-11-27
Abstract: PURPOSE:To accurately remove flashes without damaging other portions by detecting position of mold flashes adhered between a mold body and a lead pin of an electronic device and then thermally removing flashes by irradiating the mold flashes with a laser beam. CONSTITUTION:First, on the basis of a detected signal from a device position detecting means provided at the lower area of a transfer apparatus, this transfer apparatus is driven so that flashes 3 in the lateral line of the front area are located just under a laser beam irradiation block 8A. When positioning is completed, a laser beam source 19A generates a laser beam. The flash 3 in the extreme left end of the lateral line in the front area is heated and removed. In this case, an air jet is blown toward a beam spot position from an air jet blowing block 9A to remove the flash 3. Thereby, burrs may be removed without damaging the other regions.

Inventor: NAKAGAMI SHUICHI
IPC: G06K19/07
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To freely prepare protocols for controlling a non-contact type IC card (RFID) and to accelerate the processing speed. SOLUTION: Various kinds of controls are performed while using a CPU 21 in place of a conventional logic circuit and a part of a register file 1 provided inside the CPU 21 is directly connected through an RF signal line 8 to an FSK circuit 14 and a PSK circuit 15 as data transmitting and receiving means. Therefore, the data received by the FSK circuit 14, for example, can be directly inputted to a 15th register R15 without interposing an I/O port so that processing steps for inputting/outputting data can be reduced compared with the conventional case of inputting data through the I/O port. Besides, by changing the control program of the CPU 21 stored in an EEPROM 23, control protocols for instruction execution can be freely prepared.
