Abstract: PURPOSE:To surely suck and hold a work having a recessed step part at different positions by equipping a valve body to close a passage by the difference in atm. before and after the respective passage of between a suction pad and vacuum generation device, on a work suction device. CONSTITUTION:A valve device is provided between the branch pipe 6 located between a suction pad 14 and housing 7, and the main pipe 8 located between a vacuum generation device 15 and the housing 7. A spherical valve body 3 is incorporated in the valve device between each branch pipe 6 and each duct line 5 passed to a main pipe 8. The valve body 3 is ordinarily pressed to a valve seat 4 provided at the pipe 6 side by the valve body return spring 1 provided at the duct line 5 side. A hole 44 for circulating air is pierced on the valve seat 4. The valve body 3 happens to get in touch with a seal face 2 against the spring 1 in case of the pressure from the pipe 6 side being large. Consequently, in case of holding a work 11 by its suction, a pad 14 closely fitted to the work 11 completely holds the work 11 when each suction pad 14 is approached to the work 11 and the passage generating vacuum leakage is closed by the valve device.

Title: Field effect transistor
Inventor: ITOU MICHIKO
IPC: H01L29/78
Filed: 1994-10-28
Abstract: PURPOSE: To obtain an insulated gate field effect transistor excellent in cross modulation characteristics in which reduction of chip size can be realized. CONSTITUTION: The insulated gate field effect transistor has no electrode for source part or drain part in an element forming region. The source diffusion layer 4 and the drain diffusion layer 5 make a contact at source and drain lead-out parts. Since a drain electrode is eliminated and a contact is made through the diffusion layers 4, 5, the drain region is restrained from increasing due to the voltage thus obtaining an MOSFET excellent in cross modulation characteristics. Furthermore, since the source electrode can also be eliminated, the element region is decreased and reduction of chip size can be realized.
