Abstract: PURPOSE:To obtain a compact and light weight tape recorder with a simple constitution where no fault is produced even with a simultaneous operation of plural operation buttons, by giving the priority to the reproduction in case both reproduction and rapid traverse buttons are operated simultaneously. CONSTITUTION:In case an FF button 31 or an REW button 32 and a play button 23 are pushed simultaneously, a head substrate 21 moves forward. Then projected parts 21a and 21b of the substrate 21 have a horizontal touch to each other, and therefore a rapid traverse idle plate 24 is kept at a neutral position. A rapid traverse gear 16 has no engagement with a relay gear 11 together with a left reel driving disk 10. While a play idler plate engages the gear 11 or the disk 10 regardless of the buttons 31 and 32 to secure a play mode. In other words, the priority is given to the button 23 in case the button 31 or 32 and the button 23 are pushed simultaneously.

Abstract: PURPOSE:To decrease the mechanical stress, by a method wherein the print image read from a memory is vertically shifted each vertical axis according to a fixed printing paper feeding speed and supplied to a printing mechanism so that the print image may be horizontally printed. CONSTITUTION:For the print image from an input terminal 5, some vertical lines thereof are temporarily stored in a memory 1 with a control part 2, read and devided by the straight line of theta in inclined angle to the horizontal direction and at an interval of L1 in unit print length of a print mechanism 3.

Title: Gas purification catalyst and its preparation
Inventor: HASHIMOTO AKIRA
IPC: B01J23/56
Filed: 1983-07-19
Abstract: PURPOSE:To obtain inexpensive catalyst which has long life for the use at specific high temp. also, by supporting CeO2 and Pd on carrier consisting essentially of calcium aluminate. CONSTITUTION:Carrier is prepd. without performing sintering by setting a compsn. consisting essentially of calcium aluminate as binder and adding aggregate, and if necessary several additives. CeO2 and Pd are supported on the surface of the carrier. The catalyst is inexpensive since the carrier is prepd. without performing sintering. There is no need for wash coating because of its high specific surface area. The catalyst has high performance in spite of small content of CeO2 and Pd because CeO2 and Pd are dispersed uniformly by the effect of CaO contained in the carrier. The carrier causes only slight sintering even if it is used at >=900 deg.C. Therefore, only slight deterioration of performance of the catalyst is caused. Sintering of catalyst compsn. at high temp. is also slight by the interaction of CeO2 and Pd, therefore, the life of the catalyst is sufficiently long.
