Title: Wafer scrubber
Inventor: SHIRAHATA KAZUHIRO
IPC: H01L21/304
Filed: 1990-11-02
Abstract: PURPOSE:To eliminate dust, foreign material, etc., which are attaching to a wafer without damaging the wafer by installing an exhaust section to eliminate by suction force the dust, foreign material, etc., which are attaching to the surface of the wafer. CONSTITUTION:A wafer 1 is sucked by a suction wafer stage 2 which is equipped with a static eraser 15. A suction force 4 works on the surface of the wafer from a suction exhaust section 3. When the suction exhaust section 3 moves in the moving direction 5, it eliminates dust, foreign material, etc., which are attaching to the surface of the wafer 1 together with the exhaust 7. The dust, foreign material, etc., which are attaching to the surface of the wafer 1 can be eliminated by exhausting air from the surface of the wafer 1 by suction force. Therefore, an yield of non-defective elements of the wafer can be increased without giving any damage to the wafer.

Title: Bridge system
Inventor: KIMURA KOICHI
IPC: H04L12/42
Filed: 1988-11-28
Abstract: PURPOSE:To use plural physically different LANs as one logical LAN by using the PPP (priority bit) and the RRR (reservation bit) of an AO field and applying priority control. CONSTITUTION:LANs 1, 2 are local area networks, ST10 - 13, 20 - 23 are stations connecting to the LANs 1, 2, and a BR is a bridge connecting the LANs 1, 2 mutually. When a frame data is relayed from the LAN 1 to a buffer BUS 12, a priority control section P1 of the BR sets a higher priority level to the reservation bit RRR in the AC field of a frame sent through the LAN 2 and the section P1 acquires the next transmission right with priority. Similarly, a priority control section 2 reserves a higher priority level to a frame sent through the LAN 1 to acquire the transmission right. Through the operation above, the residence of a frame in the bridge BR does not take place.

Title: Constant speed running control device for automatic speed change gear type vehicle
Inventor: TERATANI TATSUO
IPC: B60K31/06
Filed: 1985-12-27
Abstract: PURPOSE:To prevent the gear shift operation of an automatic speed change gear on an ascending slope from be frequently performed (busy shift), by enabling the transmission limiting function of the constant speed running controller to be started from the outside, and by enabling the limiting function to be released until the inclina tion of the slope is lowered below a predetermined value. CONSTITUTION:A constant speed running controller A carries out the on and off-control of a control valve by an output duty ratio value D in accordance with the difference between a running vehicle speed Vn and a desired vehicle speed VM stored in a mem ory. Meanwhile, a comparator CMP1 sets its output to 1 to set a flip-flop FF when the vehicle speed Vn is lowered below a predetermined value. Further, when the vehicle speed Vn returns above the predetermined value, a output of the comparator CMP2 is counted by an overdrive return timer TOD for setting the flip-flop FF. Then, the output Q of the flip-flop FF becomes an overdrive cut-off signal which is delivered to an automatic gear shift controller B. In this arrangement such a condition that the inclination of the road surface detected by a vacuum switch is lowered, is added as the condition for resetting the flip-flop FF.
