Title: Production planning method, production planning device, article production method and recording medium
Inventor: TANI SHIGERU
IPC: G06Q50/04
Filed: 1997-09-08
Abstract: PROBLEM TO BE SOLVED: To reduce the possibility of losing an optimum solution and obtain an efficient production plan. SOLUTION: The production request quantity of each sort and the available time of each equipment are set as constraint conditions (step 100). In case of a specified continuous condition being uneffected, resource allocation operation is performed (step 104). In this operation, minimum production time and maximum production time every sort and every equipment are computed under the constraint conditions. Proposed sorts and equipments, and production time are selected from the minimum production time and maximum production time on the basis of the know-how (continuity and preparation frequency) of production processes (step 106). Since the constraint conditions change because of selecting the proposed sorts and equipments, the constraint conditions are updated (step 108), and this process is repeated until the continuous condition is uneffected.  Since resource allocation is thus performed while sequencing using know-how, the possibility of losing an optimum solution is reduced, and an efficient production planning can be obtained.

IPC: G11C17/18
Filed: 1990-09-17
Abstract: PURPOSE:To contrive the reduction of electric consumption by providing a circuit which decodes all bits in the output data of Y selector and invalidates chip enabling signals. CONSTITUTION:When the readout signals of a central processing circuit are invalidated, the enabled states of a data output buffer 5 and an address input buffer 1 are invalidated by the chip enablement from a chip enabling input buffer 7, and when all the bits of the output data of the Y selector are '1', the chip enablement through the chip enabling invalidation circuit 8 is invalidated. Thus by the chip enabling invalidation circuit 8 which decodes all the bits of the output data of the Y selector 6 and invalidates the chip enabling signals, the chip enabling signals that determine a major part of the electric consumption can be invalidated. Consequently, the reduction of the electric consumption is attained.

Title: Device structure of semiconductor device
Inventor: SOEJIMA MASAMOTO
IPC: H01L29/73
Filed: 1989-09-19
Abstract: PURPOSE:To reduce an element isolation width by a method wherein a graft base diffusion layer of a bipolar transistor is formed in common with a P<+> drain diffusion layer of a P-channel MOSFET and a P-type base diffusion layer and an N<+> emitter diffusion layer of the bipolar transistor are surrounded by the P<+> drain diffusion layer. CONSTITUTION:A dummy gate electrode 9 is formed simultaneously so as to cover a part in which a P-type base diffusion layer and an N<+> emitter diffusion layer of an NPN bipolar transistor are to be formed. Then, ions of boron are implanted to form a P<+> drain diffusion layer 6a and a P<+> source diffusion layer 6b. Gate electrodes 6 act as a mask when the ions are implanted; the P<+> drain diffusion layer 6a and the P<+> source diffusion layer 6b are formed in a self- aligned manner with the gate electrodes 8. The part where the P-type base diffusion layer and the N<+> emitter diffusion layer of the NPN bipolar transistor are to be formed is masked with the dummy gate electrode 9; as a result, the P<+> diffusion layer is not formed; however, the part is surrounded by the P<+> drain diffusion layer 6a as a graft base diffusion layer. In this manner, it is possible to sharply reduce an element isolation interval between the NPN bipolar transistor and a P-channel MOSFET.

Title: Air bag device
Inventor: YOSHIMURA HISAFUMI
IPC: B60R21/16
Filed: 1994-10-07
Abstract: PURPOSE: To equalize the contact friction between an air bag equipped in a vehicle and an interior member when the air bag is unfolded. CONSTITUTION: A folded air bag 200 is contained in an air bag module 100 equipped in the instrument panel of a vehicle. At the mounting section of the air bag 200 to the air bag module 100, one end of an inclusion cloth 300 is fixed, and the other end of the inclusion cloth 300 is a free end. When an inflator is activated, causing the air bag 200 to push and open a door 130 for unfolding, the air bag 200 contacts the door 130 and a windshield 50, receiving friction. However, since the inclusion cloth is caught between the air bag 200 and the door 130 or windshield 50, fixed friction force secures smooth development of the air bag 200.

CONSTITUTION:At the recessed section 11 of the lower surface of a cover body cover 6, the position of the upper end section 10 of a packing 9 is adjusted, and the section 10 is fitted in the section 11. In the meantime, when the induction heating coil 21 of a cover body manufacturing device is energized then heat is to be-generated from the heating plate 18 of a magnetic body. However, in this case, a holder 19 is a nonmagnetic body, and so from it, the heat is not to be generated. In its state, a device main-body 17 is set on the cover body cover 6 and descends, and then the heating plate 18 comes in contact with the rib end of the rib 14 of the cover body cover 6, and the rib 14 is heated. The heating plate 18 descends further, and the rib 14 is pushed to be deformed, and at the same time, the plate 18 descends continuously till the upper end section 10 of the packing 9 is retained by the thermally deformed rib 14.
