Title: Rubber composition for tire tread
Inventor: UCHIO TAKAYUKI
IPC: C08K5/34
Filed: 1988-02-24
Abstract: PURPOSE:To obtain a rubber composition for tire tread, improved in a coefficient of friction, by mixing a diene rubber with a specified tung oil, a triazine accelerator and a resin. CONSTITUTION:This rubber composition for tire tread comprises 100pts.wt. diene rubber, 5-20pts.wt. tung oil based on glycerides of eleostearic acid and oleic acid, 1-3pts.wt. triazine accelerator and 1-30pts.wt. resin. The triazine accelerator used means a derivative of a compound having a triazine ring. Diene rubbers include a styrene/butadiene synthetic rubber, a butadiene rubber, and isoprene rubber and a natural rubber. When the amount of the tung oil used is below 5pts.wt., the effect of improving roll workability is small, while when it exceeds 20pts.wt., the coefficient of friction is decreased, which is not practical. Examples of said resins include coumaron resin, rosin and phenol resin, and rosinous resin is mainly desirable.

Title: Multiple access communication system
Inventor: NAKAMURA MAKOTO

Filed: 1985-03-06
Abstract: PURPOSE:To improve the line utilizing efficiency even if >=2 kinds of line connection requests with different channel capacity exists by assigning each information so that a consecutive channel with large channel capacity. CONSTITUTION:In case of transmission, in general, to mobile stations 201-20n, since a band of, e.g., 5 times is required in comparison with the transmission to fixed stations 101-10n, when a transmission connection request to the fixed stations 101-10n exists, an idle channel f2 for one channel's content is retrieved from a low frequency band for assignment. When a communication connection request to the mobile stations 201-20n exists, an idle channel for 5 channel's content (e.g., a low frequency region than the f20) is retrieved from a high frequency band for assignment. In the assignment above, the line setting occupy ing one channel's content is concentrated always on the low frequency region and the line setting occupying 5 channels' content is concentrated to the high frequency region. Thus, the call loss is reduced remarkably in comparison with the conventional system where the line is set at random in this case.

Title: Operation control system for decentralized processor
Inventor: KITAURA YOSHISHIGE
IPC: G06F1/00
Filed: 1985-03-06
Abstract: PURPOSE:To attain the unmanned operation of a decentralized processor even in a hardware or software trouble mode, by performing automatically the recording of troubles and the restart of operation with no intervention of an operator. CONSTITUTION:The power supply of a decentralized processor DPU is applied to operate the DPU through a center system CPU. Then a loading action is through with the initial program of the DPU after about 3min from application of the DPU power supply. Thus the operation of the DPU is started. When a hard ware or software trouble occurs at the DPU in its operation mode, the control is shifted to a trouble processing mechanism TPU. Then the trouble information is recorded to an external memory EMU, and a stop instruction is delivered to a remote power supply controller RPU for restart of operation of the DPU. The RPU detects the stop instruction and cuts off the power supply of the DPU. Then the DPU restarts its operation automatically since the start command is always delivered to a communication circuit from the CPU after the operation of the DPU is started.

Abstract: PURPOSE:To effectively execute an element isolation operation of an integrated circuit by a method wherein a first element isolation region is formed between an active layer and a substrate and a second element isolation region is formed between semiconductor devices. CONSTITUTION:A P-type GaAs layer as a first element isolation region 12 doped with Be is formed on an undoped semiinsulating GaAs substrate 11. An undoped semiinsulating GaAs epitaxial layer 13 is grown by a vapor growth method; ions of Be are implanted by making use of a metal pattern a a mask; a P<+> type element isolation region is formed as a second element isolating region 14. A region of the epitaxial layer 13 where the ions have not been implanted is an element isolation region. If a number of elements formed on the substrate 11 are separated mutually by using a P-region, the elements can be electrically insulated completely. Since the elements are n-type field-effect transistors, an electron which has been leaked from a source 16 and a drain 17 can be stored completely by a potential of the P-region. By this setup, an element isolation operation of an integrated circuit can be executed completely.
