Title: Oil pan for engine and molding device for the same
Inventor: OKUDA TSUTOMU
IPC: F01M11/00
Filed: 1999-08-04
Abstract: PROBLEM TO BE SOLVED: To provide an oil pan which is easy to produce and excellent in durability, with a capacity to secure a necessary amount of oil. SOLUTION: An oil storage chamber 6 is provided inside an oil pan 1 and projecting walls 14 are provided on both side walls 7 of the oil pan 1. The projecting walls 14 are formed integrally with the side walls 7, such that the projecting walls 14 project outward from the side walls 7. Further, the projection walls 14 define an auxiliary oil chamber 15 in communication with the oil storage chamber 6. Unlike conventional oil pans, the oil pan 1 can be molded simply and at low cost by pressing without the necessity of troublesome work such as fixing the projection walls to the side walls by welding. Furthermore, since there is no connection portion between the projection walls 14 and the side walls 7, the oil pan 1 excels in strength and durability.

Title: Vent hold device for rim molding tool
Inventor: SHIRAKAWA MASAO
IPC: B29B7/84
Filed: 1990-08-24
Abstract: PURPOSE:To exhaust continuously gas in a recessed section of a molding tool such as a boss by providing a space for storing gas while the gas is compressed by molding pressure on the outside of the recessed section of the molding tool and communicating said space with the recessed section of the molding tool by means of a narrow passage. CONSTITUTION:Injected resin is pushed into a space 3 for storing gas through a narrow passage 4 communicating a molding tool recessed section 5 with the space 3 for storing the gas while compressing the gas in the recessed section 5 of the molding tool to raise the gas pressure in the space 3. When the resin fills completely the recessed section 5 of the molding tool and reaches an inlet of the narrow passage 4 communicating with the space 3, the volume of the space 3 is adjusted by turning an adjusting screw 1 so as to almost balance the pressure of gas pushed in with the molding pressure. As the gas pressure in the space 3 for storing the gas and the molding pressure are almost balanced as above-mentioned, the force for the action of infiltrating the resin into the narrow passage 4 gets smaller, and the resin cannot be infiltrated into the space because of fluid resistance in the narrow passage 4, surface tension of resin and the like, which eliminates the generation of blockage and molding can be carried out continuously without excess or shortage.

Title: Animal syncytium strain excreting nerve growth factor and production of nerve growth factor
Inventor: HAMADA ATSUSHI
IPC: C12N5/00
Filed: 1987-09-07
Abstract: PURPOSE:To efficiently produce NGF useful for the growth, regeneration, maintenance or the like of nerves, by fusing a mouse submandibular cell with a Chinese hamster-originated V79 cell and culturing the obtained syncytium strain in a serum-free medium. CONSTITUTION:Chinese hamster-originated V79 cells are treated with ethyl methanesulfonate to screen a clone resistant against 6-thioguanine. A mouse glandula submandibularis is extirpated, cut in small pieces and subsequently treated with tryptophane/EDTA to disperse its cells, thereby providing mouse submandibular cells. Two kinds of these cells are mixed with each other and treated with PEG 1500 to cause a fusion between the cells. The resulting syncytiums are cultured in a HAT medium and screened to give the objective syncytium having a high NGF (nerve growth factor) content. The syncytium is cultured in a serum-free medium, and the NGF is isolated from the supernatant of the cultured product.

Title: Mobile communication system
Inventor: TAJIMA ATSUSHI
IPC: H04W16/32
Filed: 1985-10-07
Abstract: PURPOSE:To attain communication with high quality similarly as an MSS having a large transmission power even in an MSS having a small transmission power by installing plural slave base stations with small transmission power in an area in service of a main radio base station of a large transmission power. CONSTITUTION:A communication line between the main radio base station MBS and a mobile communication exchange station AMS is the same form as that of a conventional system, but a part (or all) of them is connected with a slave radio base station PRS and a mobile station MSS 27 with a large transmission power communicates with an MBS 15 only. On the other hand, an MSS 28 of a small transmission power selects a nearby PRS among PRSes 17-21 to apply communication. However, the MSS 28 with small transmission power located near the MBS 15 makes communication while the transmission power of the MBS 15 is reduced from the maximum value. Since the MSS 28 with a small transmission power always makes communication with a PRS (or MBS) located in the vicinity, excellent communication is ensured even with a small transmission power.
