Title: Electrophotographic recorder
Inventor: KAWAMURA SHIZUO
IPC: G03G15/08
Filed: 1991-03-11
Abstract: PURPOSE:To eliminate the rotational irregularity of a photosensitive body without making the device expensive. CONSTITUTION:A load means 60 which prevents the photosensitive body 14 from being rotated because rotation is transmitted from a developing roller is constituted by providing O-shaped rings (friction members) 53 and 53 between the shafts 14a and 52a of the body 14 and the bearings thereof 56 and 56. At a developing time, the body 14 receives rotational load by the load means 60 and it is rotated without being followingly rotated because the rotation is transmitted from the developing roller. Then, the gear 52 of the photosensitive body and the driving transmitting gear thereof are rotated during the backlash thereof under a state that they are meshed by always being biased to one side.

IPC: C23C16/48
Filed: 1987-03-25
Abstract: PURPOSE:To easily form a W film on the surface of an insulator by radiating UV on the surface of each substrate having the insulator while in contact with a gaseous WF6-H2 mixture. CONSTITUTION:A film of an insulator such as silica, phosphosilicate glass or borophosphosilicate glass is formed on each of Si plates, part of the film is photoetched and the resulting substrates 1 are arranged in a reaction chamber 7 provided with UV sources 5. The chamber 7 is evacuated from the exhaust ports 6 and the substrates 1 are heated to 400 deg.C with a heater 2 to remove gas adsorbed on the surfaces of the substrates 1. While the substrates are kept at 250 deg.C and a gaseous WF2-H2 mixture as gaseous starting material is allowed to flow parallel to the surfaces of the substrates 1 from a gas feed pipe 3, UV is radiated on the surfaces of the substrates 1 from the UV sources 5. WF6 is reduced by H2 to deposit W on the insulators of the substrate 1. When the gaseous WF6-H2 mixture is allowed to flow perpendicularly or obliquely toward the surfaces of the substrates 1, W can be deposited on the insulators of the substrates 1 and the other parts.

Title: Data base inquiry expression processing system
Inventor: OGINOYA KAZUJI
IPC: G06F17/30
Filed: 1988-03-25
Abstract: PURPOSE:To reduce the overhead due to numerous steps required for conversion and to efficiently operate a system by adopting a tagged vector expression structure and an order table which determines the processing order of operators and successively converting intermediate results to a CNF/DNF expression at each time of detecting a partial tree. CONSTITUTION:Each character successively taken out from an inquiry expression described with operators and predicates is discriminated as a predicate or an operator: and when it is a predicate, it is converted to a tagged vector expression form by a tagged vector converting part 12 and stacked in a predicate stack 4. When it is an operator, the order table is referred to discriminated whether the priority level of this operator is higher than that of the preceding operator at the top of an operator stack 3 or not, and the operator taken out from the inquiry expression is stacked in the operator stack 3 when the priority level of this operator is higher. When the priority level of the preceding operator in the operator stack 3 is higher, a partial tree converting part 14 is instructed to apply the preceding operator to partial trees in the top and the next position of the predicate stack 4 and CNF/DNF conversion is executed. Thus, the expression of the CNF/DNF form is easily generated from the inquiry expression without passing analytic trees.
