Title: Transmission buffer circuit
Inventor: SUGIMURA KAZUHIKO
IPC: G06F12/16
Filed: 1999-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a new transmission buffer circuit with a circuit configuration by which a malfunction time due to a temporary noise or the like is minimized and which is self-restored so as not to have effect on succeeding communication. SOLUTION: The transmission buffer circuit is provided with a write end address latch circuit 15 that latches a value of a write end address of a write side address counter 12 and informs a read side address counter 13 about it. This write end address latch circuit 15 uses the value of the write side address counter 12 to self-restore the value of the read side address counter 13 when the read side address counter 13 malfunctions due to an external temporary noise or the like.

Title: Support frame for wafer line
Inventor: KIMURA SHIGERU
IPC: H01L21/677
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To smoothly separate a wafer from a wafer line by preventing the wafer from falling sideways. SOLUTION: A wafer line Wa is supported on support tubes 1 of support shafts 2, 3 and 4 by placing a fixing member onto receiving seats, the wafer line Wa is locked by moving a locking shaft 10 to the locking position A, and the fixing member 5 is removed from the wafer line Wa. One endmost wafer W is sucked by suckers 29 and moved horizontally leftward as shown in Fig. Therefore, the wafer W climbs over the support tube 1 of the support shaft 2, turned by taking the tube 1 as a support point so as to be twisted, and forcibly extracted from between the support tube 1 of the support shaft 2 and a locking tube 9. The twist rotation of the wafer W facilities the separation of the wafer W from the wafer line Wa. Since the wafer is transported in a state where the fixing member faces upward, it can be prevented from falling sideways.

Abstract: PURPOSE:To make the reduction of the diameter of working roll possible and to drastically enlarge the capacity of shape control while making use of the feature of 2H mill which is suitable in the surface quality of plate in a plate mill, especially a skin-pass mill. CONSTITUTION:Contact with a working roll is cut off by reducing the diameter of a back-up roll 1 in the part corresponding to the width B of plate.

Filed: 1984-05-15
Abstract: PURPOSE:To make it possible to lead out an electrode which has better leveling and does not cause a step coverage problem without increasing contact resistance between the electrode and the semiconductor substrate, by a method in which, after the silicon being buried partially is changed to metal silicide with high melting point, high melting-point metal is deposited thereon to bury the entire window for taking out the electrode. CONSTITUTION:An electrode lead-out window 3 is formed through the insulating layer 2 over the N type silicon layer 1. After a doped polycrystalline or amorphous silicon layer 5 is buried into the window 3 partially, it is changed to tungsten silicide at the surface or as a whole by being reacted with tungsten hexafluoride WF6. Next, by flowing hydrogen in place of nitrogen, a tungsten layer 4 can be rapidly grown on the polycrystalline or amorphous silicon layer 5 to bury the entire window 3. Thereafter, the tungsten layer 4 or an aluminum layer coated thereon may be employed as a wiring layer.
