Title: Electric shock preventing circuit
Inventor: MIYAMOTO TOSHIHIDE
IPC: H02H5/12
Filed: 1991-05-22
Abstract: PURPOSE:To protect a worker against electric shock in live area (access area). CONSTITUTION:When a worker stretches his hand into an access area 101 for the purpose of maintenance, optical path between a projector 3 and a light receiver 4 is blocked. The light receiver 4 notifies blockage of optical path to a microprocessor 6 and a current interrupting switch 5 is opened by means of a switching command circuit 7 and a switching operating unit 8. Consequently, current flow through a current path 102 is interrupted automatically, and an indicator lamp 9 is lighted. When the arm of the worker gets out of the access area 101, current flow through the current path 102 is reset automatically in reverse manner and the indicating lamp 9 unlights.

Title: Method for cutting wafer-protecting film
Inventor: FUNAKOSHI KEIGO
IPC: H01L21/683
Filed: 1985-05-30
Abstract: PURPOSE:To protect the circumference of a wafer from a cutter in the absence of proficiency in hand-work by a method wherein an adsorption table is caused to rotate, the cutter is guided so that it may be positioned in the vicinity of the wafer circumference, and a protecting film is cut along the wafer circumference. CONSTITUTION:A wafer 50 is adsorbed to the upper surface and secured thereon. A vacuum type adsorption table 6, to work for example for the application of a protecting film to the wafer 50, is installed, capable of rotation and elevation. The wafer 50 is adsorbed to the adsorption table 6, applied with a tape-shape protecting film, and then the tape-shape protecting film applied to the wafer 50 is disconnected from the rest of the tape-shape protecting film. Next, the adsorption table 6 is caused to go up, causing the protecting film to be pelled off from the portion not rotatable. The adsorption table 6 is caused to rotate and a cutter 48 is guided so that it may be positioned in the vicinity of the circumference of the wafer 50, for the cutting-off of the protective film along the circumference of the wafer 50. The cutter 48 may be guided, for example, by a cam 21, with its external appearance very similar to the shape of the wafer 50. The cam 21 is caused to rotate in synchronism with the adsorbing table 6 for the guidance of the cutter 48.
