Title: Preparation of metal oxide catalyst and catalyst burner
Inventor: HANAKADA YOSHIO
IPC: B01J23/64
Filed: 1995-03-08
Abstract: PURPOSE: To prevent the lowering of activities following oxygen dissociation at high temperature while temperature control properties are retained by reducing the metal oxide constituting a catalytically active component and then oxidizing it again. CONSTITUTION: A catalytically active component is composed mainly of a metal oxide having the equilibrium relation of an oxide, a metal + oxygen (reversible relation between oxide and metal + oxygen), for instance, palladium oxide at a specified temperature. The component is carried on a heat-resistance substance carrier to prepare a metal oxide catalyst. In this case, the catalytically active component, for instance, palladium oxide, is reduced. Then the component is oxidized again. Heat stability is improved by the above constitution, and oxygen can be dissociated at higher temperature. A honeycomb type catalyst is provided in a gas feed line 6 by utilizing this catalyst, and fuel gas is fed from a fuel gas feed opening 6a and flowed as mixed gas and burnt.

Abstract: PROBLEM TO BE SOLVED: To correct the attitude of a thread member wound on a veneer by providing a correcting body abutting on a plurality of lines of the thread member longitudinally wound on a roll in forward movement to hold it and bringing each held thread member in a stretched state in descending. SOLUTION: An arm 73 is actuated to abut a correcting body 76 on the downstream longitudinal direction of a roll 3. A plurality of lines of a thread member 35 is sucked and held by the correcting body 76 through a suction port provided on the side facing the roll 3 of the correcting body 76. After the suction and holding, a moving block 71 is lowered with the position to the roll 3 of the correcting body 76 locked. Consequently, the thread member 35 is laid in a stretched state until the moving block 71 reaches the descending limit position even if the end of the thread member 35 is entangled in the fiber of a veneer, or the suspending position is displaced by the entanglement in the fuzzy fiber on the surface, and the entwinement is solved. When the holding state is released, the thread member 35 is suspended right down, and the attitude is corrected.

IPC: G01R31/30
Filed: 1988-03-04
Abstract: PURPOSE:To secure a means for securely and easily monitoring clock burn-in operation by widening the width of clock pulses by prescribed time width when a clock waveform is monitored. CONSTITUTION:When the clock waveform is monitored by the dynamic burn-in device for screening a semiconductor device, the width of clock pulses is widened by the time width which is long enough to monitor a normal clock period, e.g. by a multiple of the wavelength, and the device is put in operation at the normal clock period after the monitoring operation. Namely, a basic clock generating circuit 1 generates basic clock pulses and a dummy clock waveform generated by a dummy clock generating circuit 2 is put together with the clock pulses by an OR circuit 6, whose output is outputted from a driver circuit 7. The dummy clock waveform is superposed upon the basic clock waveform and the synthesized waveform is supplied to the device. The synthesized clock waveform is outputted repeatedly at a period set with a time setting switch 3 and also supplied to the device, so that it is monitored as a return waveform with the clock waveform.

Title: Visual field frame displaying camera

IPC: G03B13/16
Filed: 1988-03-04
Abstract: PURPOSE:To correctly adjust a visual field frame by arranging a visual field switching part on the optical path of a finder optical system, and providing said part with plural visual field frame displaying means changing visual field frames by turn-on/turn- off control based on range-finding information obtained through automatic focusing. CONSTITUTION:Based on range finding information obtained by an autofocusing (AF) range arithmetic part 12, a liquid crystal driver 14 is controlled. The visual field switching part 8 is provided with plural liquid crystal cells 15a-15c. The liquid crystal driver 14 removes visual field frames by controlling the plural liquid crystal cells 15a-15c to turn on/off them, and corrects various visual field frames. AF range finding is performed through a release semi-press switch SW 11 to drive a focus lens. If releasing is not carried out after the visual field frames are corrected by driving the liquid crystal driver 14 and AF range-finding area display is corrected, operation returns to the start point. On the other hand, if releasing is carried out, operation returns to the start point through exposure. In such a way AF range finding is carried out, and the visual field frames are corrected. Thus, the high accuracy finder optical system switching the visual field frame in response to a photographing distance can be obtained.

Title: Logic circuit for bipolar cmos structure
Inventor: ANDO KOICHI
IPC: H03K19/08
Filed: 1990-02-28
Abstract: PURPOSE:To perform the high-speed operation by using the inverted signal of a signal, which is inputted to the basse of a first bipolar transistor TR, as the gate input of a MOS TR which discharges the base electric charge of a second bipolar TR. CONSTITUTION:When an input signal IN is switched from the low level to the high level, a bipolar TR Q2 is turned on, but an N-channel MOS TR MN1 is turned on to discharge the base electric charge of a TR Q1. Therefore, the TR Q1 is turned off when the TR Q2 is turned on. An N-channel MOS TR MN3 provided to discharge the base electric charge of the TR Q2 is turned on after the input signal is switched from the low level to the high level. Since discharging of the base electric charge of the TR Q2 is started then, discharging of the base electric charge of the TR Q2 is completed when the input signal is next switched from the high level to the low level and the TR Q1 is turned on. Thus, the through current does not flow because TRs Q1 and Q2 are not simultaneously turned on.
