Abstract: PURPOSE:To make the operation of a FF circuit stable by replacing 2nd and 4th switching elements by 1st and 2nd impedance elements respectively. CONSTITUTION:The 1st impedance element 61 acts like as if disconnecting the output side of the 2nd inverter 52 from the input of the 1st inverter 51 when the 1st switching element 41 is turned on and like transferring the output of the 2nd inverter 52 to the input of the 1st inverter 51 to keep the input level while the 1st switching element 41 is turned off.

Abstract: PROBLEM TO BE SOLVED: To effectively deal a packaged condition clustering on one side created at vacuum packaging in a slanted condition. SOLUTION: This packaging machine is provided with a multipurpose vacuum position Pb in addition to an ordinary vacuum position Pa. After vacuum package treatment at the ordinary vacuum position, a packaged article (m) sent by the movement of a transfer belt 1 is treated as necessary at the multipurpose vacuum position and thus a packaged condition clustering on one side can be easily corrected. To be specific, by placing the packaged article in a pressure reduced atmosphere using a second chamber box 3b provided at the multipurpose vacuum position, a strong vacuum condition is temporarily weakened. In this condition, the packaged condition clustering on one side can be corrected by, for example, slightly slanting the packaged article in an opposite direction from the ordinary vacuum position.

IPC: B01J23/38
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To inhibit the sulfur poisoning of an NOx occluding element such as an alkaline metal, an alkaline earth metal or a rare earth element beyond the present effective level and further enhance the cleaning activity by making a porous oxide carrier bearing a specific metallic oxide and a precious metal carry the NOx occluding element. SOLUTION: First a composite oxide consisting of the atoms of metals such as Ti, Zr, Si and Ce and a noble metal atom is borne by a porous oxide carrier, and then the composite oxide thus borne by the carrier is decomposed. Since the atoms of the metals such as Ti, Zr, Si and Ce and the noble metal atom are set in a close proximity to each other on the atomic level in the composite oxide, it is possible to bear the oxides of TiO2, ZrO2, SiO2 and CeO2 and the noble metal as proximity fine particles on the porous oxide carrier. In addition, an NO occluding element such as an alkaline metal, an alkaline earth metal, a rare earth element or the like is borne by the porous oxide carrier. The porous oxide carrier is preferably γ-Ale2O3.

IPC: G01R31/14
Filed: 1989-06-05
Abstract: PURPOSE:To output a sine wave ultra low frequency with high efficiency and high accruacy even when L,C, and R or their mixed load is driven by performing phase control by a switching means. CONSTITUTION:When a power source frequency is f0, a power source cycle t0 is (1/2f0) and when an ultra low output frequency f/f0 is (n), a switching period T is t0+(t0/n). A switch driving circuit 3 turns on switching elements 2a and 2b for previously set width in a cycle T. The elements 2a and 2b are connected to one terminal or the other terminal of the secondary side S of a transformer 4 alternately. When the output waveform AC of the secondary side S is switched, the polarity of a switched output voltage is inverted in every half cycle of the waveform. Consequently, a pulse train whose amplitude varies smoothly is obtained and the phase of the pulse train leads the phase of a power source by t0/n. The pulse train is smoothed by a filter 5 to generate the target ultra low frequency P.
