Title: Production of fluoroethane
Inventor: YAMAGAMI ISAO
IPC: C07C19/12
Filed: 1990-08-08
Abstract: PURPOSE:To obtain fluoroethane useful as a refrigerant, foaming agent, etc., by reacting chlorofluoroethane with hydrogen in the presence of a Pd catalyst supported on a preferably fluorinated silica carrier. CONSTITUTION:A compound expressed by formula I (X<1> to X<5> are H, F or Cl and at least one thereof is F) (e.g. 2-chloro-1,1,1,2-tetrafluroethane) is reacted with hydrogen in the presence of a Pd catalyst supported on a silica carrier at 180-300 deg.C to afford a compound expressed by formula II (Y<1> to Y<5> are H, F or Cl and at least one thereof is F). The amount of Pd supported on the carrier of the Pd/silica catalyst is >=0.05wt.%. Since the proper reaction temperature for the catalyst is low, excessive hydrogenating reaction is suppressed with hardly any formation of by-products. When a fluorinated silica carrier is used, acid resistance is high and adsorptivity of acidic substances is low. Thereby, since HCl or HF is removed from reaction points, side reaction is hardly advanced.

IPC: G06F12/08
Filed: 1989-08-14
Abstract: PURPOSE:To naturally execute information update processing for address extension by judging whether information for address extension concerning a memory area belongs to a task presently under execution or not, and rewriting the information to the information of the task under execution when the information do not belong to the task under execution. CONSTITUTION:When the extention memory area is accessed during task execution, the information from a task ID memory 2, to which an information group memory 1 for extended address belongs, are compared with the information from a task ID memory 3 under execution. When the information are not coincident, the information for the extended address do not belong to the task under execution. A trap signal 6 is sent out to an instruction sequencer 5 and control is moved to update processing. Then, the information belonging to the respective tasks held on a memory 7 are set to the information group memory 1 for address extension and simultaneously, the task ID memory 2, which is paired with the information, is also updated to the task ID presently under execution. Thus, it is not necessary to execute the update processing of the information for address extension each time the task is switched.

Filed: 1996-08-09
Abstract: PROBLEM TO BE SOLVED: To provide an air bag device for a vehicular seat, which can certainly open only the nominal joint parts without bringing about degradation of the appearance. SOLUTION: A reinforcing sheet S1 is provided on the rear surface of the gore part 17 of a vehicular seat, and because the sheet S1 has a strength higher than the gore part 17 and also an expansiveness not more than the gore part 17, the inflating force of the air bag concerned 10 is received by the sheet S1 , and no force will act directly on the gore part 17. Therefore, the gore part 17 will never be ruptured in any part on the way other than the joint parts H1 and H2 . As the air bag 10 spread forward, the rupture is made certainly from the nominal joint part H1 situated in front. There is no risk either that the appearance is degraded because the reinforcing sheet S1 is located on the back of the gore part 17.

Abstract: PURPOSE:To attain monitoring of a lot of signals by small size and at a low cost by a few digital circuits by constituting a titled circuit of plural pulse encoding circuits, a clock generating circuit, an ROM and two series-parallel converting circuits. CONSTITUTION:An input signal inputted to encoding circuits CODER1-4 from input terminals 1-4 is converted to a series digital code by a clock pulse from a clock pulse generating circuit CLK. A series-parallel converting circuit CONV1 converts an input code in parallel and outputs it, and supplies it as an address code to an ROM. A logical value in the ROM is set in advance so as to show whether a level of the input signal is normal or not. Accordingly, from the ROM, a result of decision as to whether the level of the input signal inputted to the terminals 1-4 is normal or not is outputted successively in series. When this series output is converted to a parallel output by a CONV2, an alarm signal corresponding to the input signal of the terminals 1-4 is outputted from output terminals 1'-4', respectively.
