Title: Fluid pressure control unit for dual piping system
Inventor: FUJITA TOMOHIRO
IPC: B60T8/26
Filed: 1981-04-14
Abstract: PURPOSE:To stabilize the output fluid pressure of an active system, and to facilitate the working step of air vent by utilizing a retainer for limiting the displacement of a balance piston to a necessary and satispactory value. CONSTITUTION:A control piston 11 and a control spring 14 regulate the fluid pressure in an active system (a), and a balance piston 15 exposed to an output fluid pressure chamber a2 in the active system (a) regulates the fluid pressure in a follow-up system (b). The displacement of the balance piston 15 toward the output chamber a2 of the active system is limited by a retainer 24 to a value necessary for actuating a valve 17. Therefore, the volume of the output fluid chamber a2 does not greately change, even if the actuation of the balance piston 15 is delayed due to seal resistance or the like, duly causing occurrence of overshooting, thereby the output fluid pressure is stabilized. Further, the working step of air vent is facilitated, since the balance piston 15 is prevented from pushing the control piston during the air vent work.

Abstract: PROBLEM TO BE SOLVED: To increase the activation concentration of an imputity diffusion layer, and realize low resistance contact with metal. SOLUTION: In the surface of an Si substrate 1, an impurity diffusion layer 4a is formed with which an Al electrode 6 is in contact from above. The surface layer 4a contains Ge concentration of at least 1×10<21> cm<-3> as impurities for changing the lattice constant, in the thermally non-equilibrium state. The lattice constant of the surface layer 4a is set larger than that of Si containing the same concentration Ge in the thermal equilibrium state. Thereby the height of a Schottky barrier of a contact formed between the surface layer 4a and the electrode 6 is decreased. The surface layer 4a contains electrically active B as impurities for imparting carriers. The concentration of B is higher than or equal to the solubility limit in the thermal equilibrium state in Si. By containing Ge, the mobility of the carrier in the surface layer 4a becomes larger than the mobility in Si.

Filed: 1990-03-09
Abstract: PURPOSE:To perform complicated processing with the small number of instruction codes by substituting the instruction code of an instruction group stored in a buffer for instruction group for the instruction code stored in an instruction queue when a prescribed instruction code is detected. CONSTITUTION:When the instruction code stored in an instruction register IR 7 is the one for instruction group, a fetch operation from a memory 1 by a memory access circuit 3 is suppressed, and a transfer bus 4 to a queue is invalidated. Instead of that, the instruction group stored in a buffer 11 for instruction is transferred to the instruction queue 5. Therefore, the instruction to be executed next in the instruction group goes to the instruction group placed in the buffer 11. At this time, the instruction code stored in the queue 5 is invalidated, and the instruction group transferred to the queue 5 is executed, and after that, the circuit 3 fetches the instruction code from the memory 1, and transfers it to the queue 5. In such a way, it is possible to execute plural instructions with only one code for instruction group placed in the memory 1.
