Title: Catalyst for dehydrogenation reaction
Inventor: ABE TOSHIHIRO
IPC: B01J35/02
Filed: 1979-10-22
Abstract: PURPOSE: To obtain a catalyst for dehydrogenation reaction, having a high side reaction suppression as well as a high selectivity, by supporting a compund of Fe, etc., on a metallic material structure partitioning a fluid pathway leading from inlet to outlet.  
     CONSTITUTION: A dehydrogenation catalyst, on which a monoolefin or alkylated aromatic compound is dehydrogenated to form conjugated diene or alkenylated aromatic compound, is obtained by holding one or more of the compounds of Fe, Cr, or other elements on a metallic material structure having plural pathways leading from the inlet to the outlet of fluid, partitioned by thin walls. The catalyst can lower the whole pressure of reaction system because of less pressure loss and also can raise the selective formation of objective compound because of its high side reaction suppression.

Title: Detecting method of ground fault
Inventor: KAJIWARA YOSHIHIRO
IPC: H02H3/38
Filed: 1995-06-01
Abstract: PURPOSE: To detect a ground fault and to know the direction thereof by incrementing a condition establishment counter on the basis of a phase angle of a zero-phase current to a zero-phase voltage and by detecting the ground fault from a value of the counter. CONSTITUTION: Based on an output signal of a digital filter of a filter part 11, an arithmetic part 12 carries out computation of the respective effective values for a commercial frequency of zero-phase voltage and current, computation of a phase difference and determination of a lead/delay of the zero-phase current in relation to the zero-phase voltage, makes determination as to whether each effective value is a set value or above and as to whether a phase angle of the zero-phase current in relation to the zero-phase voltage is within a set range, and increments a condition establishment counter (f) by one only when all of these AND conditions are established, while it clears a condition failure counter (g) at the same time.  A time point when the condition establishment counter (f) reaches a specified value comes to be the point of detection of a ground fault and a value set initially in the condition establishment counter (f) comes to be the time of detection of the fault.
