Title: Device and method for operating set of server computer using double duty proxy server computer
Inventor: KATIYAR DINESH
IPC: G06F9/46
Filed: 1997-07-02
Abstract: PROBLEM TO BE SOLVED: To secure the clear function of a server set together with its technical precision and compactness. SOLUTION: A set of an SC(server computer) includes. a PSC (double duty proxy server computer) and a pair of Non-PSC (non-proxy server computers). A pair of CC(client computers) generate the RPC (remote procedure calls) to the objects stored in the set of the SC. The RPC include a non-client RPC to the PSC and the client RPC to the Non-PSC respectively. The PSC processes the client RPC only when a pair of Non-PSC cannot process the client RPC. The processing carried out by the PSC to the client RPC causes the transfer of information and accordingly the client RPC acquires the service from the Non-PSC.

IPC: H01L29/732
Filed: 1988-07-18
Abstract: PURPOSE:To improve a high-frequency characteristic by providing the following in prescribed regions of a well: a base diffusion layer; a doped region mounting on it for contact use; a base electrode formed on the region; an emitter diffusion region, of one conductivity type, formed in a part where the base electrode is not formed; a collector diffusion region. CONSTITUTION:A base-collector capacitance is generated on a contact face between a base diffusion layer and a well 4; however, the base-collector capacitance is reduced by an amount caused by a fact that a base-collector junction does not exist between a base electrode 7 and an emitter electrode 11 and a LOCOS 3. In addition, when a doped region 8, for contact use, utilizing a base contact window 6 is formed, a contact can be formed with good positional accuracy; after the base electrode 7 has been formed, the surface is covered with an insulating film; accordingly, the emitter electrode 11 does not come into contact with the base electrode 7. In addition, when an emitter diffusion region 9 is formed, the base electrode is utilized as a mask; accordingly, a size and a position can be decided accurately. Thereby, a high-frequency characteristic can be improved.

Abstract: PURPOSE:To check the damage of glass in the material metered in the tip part of a plunger to the minimum and consequently realize a favorable quality injection molded item by a method wherein a pressing line, which energizes the plunger in the direction of its retreat during its metering, is provided on an injection cylinder. CONSTITUTION:Under the state that a plunger 24 is located at its advancing limit and rotted at about 5-150rpm, material such as BMC or the like is charged in a stuffer 27 in order to push down the material with a stuffer plunger 30. By being pushed down, the material is sent forward through the outer peripheral part of the plunger 24 and a check ring 23 so as to be gradually accumulated in a barrel 22 ahead the plunger 24. In this case, high pressure is applied through a pressing line 78 to the left chamber 72 of an injection cylinder 72 connected to the rear of the plunger 24 in order to apply rightward pressure to a piston rod 73. As a result, the pressure opposing to the back pressure is applied to the plunger 24, resulting in making the retreating resistance of the plunger 24 during its retreat following metering smaller, and accordingly the retreat motion of the plunger 24 becomes smoother.
