Title: Method of laying signal wire covered with soft material in pipe
Inventor: IMAMURA MINORU
IPC: H02G1/08
Filed: 1992-02-10
Abstract: PURPOSE:To get a laying method which does not damage a signal wire when laying a signal wire covered with a soft material in a pipe. CONSTITUTION:A signal wire a is laid by inserting a coil 10 first, making use of an inserter 11, and inserting the signal wire 1 into a pipe 1 via the coil 10, and withdrawing only the coil 10. Hereby, the signal wire a is never damaged by burrs since it is protested with the coil 10 at insertion. As a result, since the signal wire covered with ordinary synthetic resin or the like can be used, the cost of the signal wire is low, and also since the resistance in insertion is small, the insertion work is very easy.

Filed: 1980-02-29
Abstract: PURPOSE:To make the read on high speed and extend the operation margin, by reducing the load capacity of the bit sense circuit array at the signal read time and by preventing every memory block from being influenced by unbalanced wiring capacities. CONSTITUTION:Data from memory cell array 21 read out through a pair of data signal input/output lines 23 of bit sense circuit array 22 is transferred to the first and second data signal input/output parts 26 and 27 of data signal transfer circuit 25. At this time, since MOSFETs 51 and 52 of circuit 25 are nonconductive by the control pulse, input/output parts 26 and 27 are cut off from the third and the fourth data signal input/output parts 28 and 29 of circuit 25, and the load capacity through a pair of input/output lines 301 is reduced at the data read time to perform high- speed read. Further, when FETs 51 and 52 are conductive, read data of input/ output parts 26 and 27 which are differentially amplified by MOSFETs 53-57 sufficiently are applied from input/output parts 28 and 29 to multiplexer 31 without  the influence of unbalance of the wiring capacities, and thus, the operation margin  is extended.

Title: Particulate filter and production thereof
Inventor: WATANABE YOSHIMASA
IPC: B01D39/20
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To reduce the production cost of a roll-shaped particulate filter. SOLUTION: A bag-shaped filter material unit 13 (13a, 13b) is preliminarily formed by inserting a corrugated plate as a separation member between two filter flat plates comprising a nowoven fabric made of a metal in a lamination state and welding the end parts of the filter flat plates 5. A plurality of the filter material units 13 (13a, 13b) are wound into a roll shape in a laminated state to form a filter unit 10. Since a process for mutually welding the filter flat plates after the filter material units are wound into a roll shape can be avoided, the production time and cost of a particulate filter can be reduced.
