Title: Static random access memory
Inventor: EKI KENU
IPC: G11C11/419
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To simultaneously carry out read operation and write operation to different memory banks while keeping a one-port structure, by determining the number of memory cells of a plurality of memory banks. SOLUTION: A read-enable clock signal and a write-enable clock signal are set to the same clock frequency. Supposing that the number of memories of an SRAM is N and every memory cell can be serially accessed, accessing to data is sequentially carried out from the first memory cell to an Nth memory cell while both read and write enable clock signals are at a high level. The write enable clock signal rises earlier than the read enable clock signal, and therefore a read operation is not executed when data are written to the first memory cell. A collision of read and write operations is not brought about. At the write time to an Ath cell, data banks are always separated by different paths in accordance with a length of A memory cells of an area 10.

Title: Fully inverted soi mosfet
Inventor: SUGANO TAKUO
IPC: H01L29/786
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a high-performance transistor which constitutes the next- generation semiconductor integrated circuit for which superhigh-density integration and extremely low power consumption are required. SOLUTION: In a fully inverted SOI MOSFET, the termination of an electric force line from a gate in an ionized impurity in a space charge layer is eliminated by distinguishing the space charge layer by making a top silicon layer sufficiently thin and, in addition, the termination of the electric force line from the gate to substrate charges is suppressed by making the top silicon layer and an insulating film between substrates sufficiently thicker. Since the top silicon layer is made sufficiently thinner in the SOI MOSFET, the top silicon layer underlying the gate is set to an inverted state in which the space charge area is distinguished over the whole area of the top silicon layer when the transistor is operated and the control of channel charges by means of a gate electric field can be made more efficient.  Consequently, an improvement of characteristics, such as the suppression of short-channel effects, etc., can be expected from the transistor.

Title: Traction device for towing tractor
Inventor: KAJINO KATSUO
IPC: B60D1/26
Filed: 1990-05-11
Abstract: PURPOSE:To prevent the slip-off of a draw bar pin during its upward thrust motion by moving a draw bar link along the slotted hole of a draw bar lever, and bringing the contact face of the draw bar link into strong contact with the contact face of a draw bar bracket. CONSTITUTION:When a draw bar pin 2 is thrusted up by a truck, a draw bar link 3 is also about to move upward in linkage with the upward motion of the draw bar pin 2. Since one end of the draw bar link 3 is connected to a draw bar lever 4 through a connecting pin 34 inserted through a slotted hole 40, the draw bar link 3 moves in the direction B along the slotted hole 40. As a result, the contact face 30 of the draw bar link 3 comes in contact with the contact face 10 of a draw bar bracket 1. The upward thrust force acting upon the draw bar pin 2 thereby escapes onto the base 11 side of the draw bar bracket 1 to stop the ascent of the draw bar pin 2. The draw bar pin 2 is therefore prevented from slipping out of the draw bar bracket 1.
