Title: Catalytic thermal cracking catalyst of nitrogen dioxide
Inventor: KATOU YASUYOSHI
IPC: B01D53/94
Filed: 1982-11-09
Abstract: PURPOSE:To obtain a catalyst applicable to a catalytically reductive denitration method of ammonia for suppressing N2O as a byproduct, by constituting the same from one prepared by supporting oxide of one or more of a metal element selected from Mn, Co, Cr and Cu by a carrier. CONSTITUTION:The titled catalyst is constituted of one prepared by supporting oxide of one or more of a metal element selected from a group comprising Mn, Co, Cr and Cu by a carrier. Powders comprising oxides of these metal elements are mixed in a dry or a wet system and the resulting mixture is dried, molded and baked to obtain an objective catalyst. Thus obtained catalyst can preliminarily convert NO2 contained in exhaust gas to NO in good efficiency in a denitration process due to catalytic reduction for ammonia and, as the result, the generation of N2O as a byproduct in denitration reaction is suppressed and a denitration process for NO2-containing gas can be realized in a high denitration ratio.

Title: Printed wiring board
Inventor: SATO TOMIO
IPC: H05K3/34
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To realize a low price printed wiring board by employing such a structure as a required quantity of solder is stored at a snaking part of a lead pattern thereby reducing production cost of printed wiring board. SOLUTION: A printed wiring board 2 is provided, on the surface thereof, with lands 3 for mounting electronic components 1 and external mounting terminals 4 for connection with an external circuit wherein the lands 3 are connected with the external mounting terminal 4 by means of a print pattern 5 which is exposed partially through recesses 6. Since a required quantity of solder is stored at a deformed part 7 of the print pattern 5, heat storage capacity is enhanced as compared with a structure for connecting linearly through a print pattern and thereby transmission of heat to an electronic component 1 can be retarded. Since no adhesive is required for bonding an electronic component, manufacturing cost is reduced and a low price electronic component is realized.

Title: Magnetic tape reproducing device
Inventor: HIDA YOSHIYUKI
IPC: G11B15/467
Filed: 1989-07-27
Abstract: PURPOSE:To accurately detect a synchronizing signal and to perform the stable tracking by counting a period of the detected synchronizing signal with counters when the synchronizing signal is detected by a synchronization detecting circuit and controlling the starting time and the ending time of the counters with signals to be outputted from a continuous Hi detecting circuit and a continuous Lo detecting circuit. CONSTITUTION:An output of a comparator 131 tends to generate a beard in the vicinity of its rise and fall. Even in this case, the commencement and completion of two counters 134 and 135 are controlled by using a detecting output of the continuous Hi detecting circuit 132 for detecting the continuation of Hi for a prescribed time and a detecting output of the continuous Lo detecting circuit 133 for detecting the continuation of Lo in level for a prescribed time when a Hi section and a Lo section of the output of the comparator 131 are counted by the two counters 134 and 135. Thus, a malfunction of a time measuring circuit due to noise can be prevented. By this method, the accurate synchronizing signal can be detected, and the accurate tracking is feasible, and hence the stable reproducing device can be obtained.
