IPC: B01J23/75
Filed: 1988-02-05
Abstract: PURPOSE:To increase reactive selectivity by permitting a catalyst carrier consisting of spinel crystal to carry transition metal selected from among Mo, Co, Ni and W as a catalytic activate component and thereby forming a catalyst for hydrogenation. CONSTITUTION:The carrier is made from an aq. nitrate solution 2 or 3 elements selected among Al, Mg, Co, Ni and Ga, mixed them stoichiometrically so as to form the spinel crystalline structure and spray thermal decomposed it.

Title: Latch circuit
Inventor: KOYA HIROSHI
IPC: H03K17/687
Filed: 1986-02-07
Abstract: PURPOSE:To attain high speed operation by applying an input data to a gate of the 1st complementary field effect transistor (TR) so as to eliminate the need for the direct drive of the input data to a parasitic capacitance of a data storage means. CONSTITUTION:A passing control signal D is brought into a high level at the data latch, the 2nd complementary field effect TR 24 is turned on, and an input data signal B, e.g., a high level signal is fed. The high level input data signal fed to an input node 28 turns on an N-channel TR, while a P-channel TR is turned off and a ground potential is sent to an output node 29 via the 2nd complementary field effect TR 24. The inverted input data signal B is stored in inverters 25, 26 and when the passing control signal D goes again to a low level, the output node 29 is cut off from the 1st complementary field effect TR 23. Since the input data signal B has only to drive only the gate parasitic capacitance of the 1st complementary field effect TR 23 in this way, high speed operation is attained.

Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To obtain a small size inverter apparatus at a low cost by controlling ON and OFF the one upper-/lower-arms of a single phase bridge inverter circuit with a drive signal of the first signal wave, and then controlling ON and OFF the other upper-/lower-arms of a single phase bridge inverter circuit with a drive signal of the second signal wave.

When the triangular carrier signal Vc and second signal wave are in the relationship of the second signal wave >Vc in the second comparison arithmetic circuit 17, Q4 starts the operation to become OFF from ON and Q3 starts the operation to become OFF from ON. As a result, the inverter as a whole can be reduced in size and formed in the low price.

Abstract: PURPOSE:To prevent the erasure of data by writing the produced data onto a flexible disk when an error trap occurs. CONSTITUTION:A switch is provided (steps 11 and 12) to designate whether the data designated previously is written on a flexible disk or not with occurrence of an error trap together with a means which sets (step 13) a new instruction including a saving variable name in its parameter when the data is carried out, and a storage means where a data saving processing flag to which the presence or absence of the data saving is written and a saving variable name store table are set in a work area.

Title: Multi-element thin film magnetic head
Inventor: SASAKI TAKUMI
IPC: G11B5/31
Filed: 1984-02-17
Abstract: PURPOSE:To realize a multi-element thin film magnetic head which is scarcely affected by magnetic fluxes leaking out from adjacent tracks, by cutting out two chips different in azimuth angle from a bonding block, and joining them with a conductive spacer in between. CONSTITUTION:Two chips having different azimuth angles are cut out from a bonding block which is formed in such a way that layers 8a, 9a, 8b, and 9b of a magnetic substance, such as ''Permalloy'', etc., are formed on non-magnetic substrates 6a, 7a, 6b, and 7b made of glass, etc., and they are joined with a non-magnetic layer which becomes a magnetic gap in between. The magnetic head of this invention is manufactured by joining them with a conductive spacer 13 having a thickness which is almost the same as the distance between the chips between them and installing windings to the joined body. Because of the azimuth effect, influences of magnetic fluxes leaking out from adjacent tracks can be minimized. Moreover, crosstalks can also be reduced because eddy currents produced in the spacer 13 prevent the leaking magnetic fluxes from passing through.
