IPC: G11C11/407
Filed: 1998-02-02
Abstract: PROBLEM TO BE SOLVED: To obtain a circuit capable of adjusting a time for delaying propagation also with respect to a higher clock speed after preparing a semiconductor circuit by connecting first and second gate elements in parallel, arranging a delay element to the second gate element in series and gate-controlling one of the first and second gate elements to output an input signal. SOLUTION: When the data values of SRAM (2a, 2b, 2c and 2d) are 1, 0, 0 and 0, a try state gate 4a comes into an enabled state and a signal inputted to an I/O pin passes through the gate 4a. Then the signal can be propagated to a logic block 13 by way of a delay time of one stage of a gate. At this time the outputs of try state gates 4b to 4d are in a high impedance state and never interferes with the output of the gate 4a. On the other hand, when the data values of SRAM (2a, 2b, 2c and 2d) are 0, 1, 0 and 0, the signal can be propagated to the block 13.

Title: Magnet packing
Inventor: TAKAYAMA HARUYUKI
IPC: F25D23/02
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To improve expandability and contractibility without lowering heat insulation, by setting a thickness of a site of a partition wall to be applied by a tensile force to a specific range when a door of air chambers divided by a plurality of partition walls is opened. SOLUTION: Since a site of a partition having a thickness is disposed at a site to be applied by a tensile force when a refrigerator door 3 is opened, an overall thickness of the partition wall applied by the force when the door 3 is opened is set to 0.7 to 2.5 mm. If the thickness is less than 0.7 mm, when the door 3 is opened, a thin part of a magnet packing 4 is excessively elongated, and the door is not smoothly opened. If it exceeds 2.5 mm, its expandability and contractibility become insufficient so that a sealing function is lowered. Thus, the pacing having suitable expandability and contractibility can be obtained without lowering the heat insulation.
