Abstract: The pipelined central processing system (CSS) units of a multiprocessor system are tightly coupled to connect in common to a system bus for sharing main memory and input/output controllers/devices. The CSS includes several circuit boards for the different VLSI circuit chip pipelined stages and associated control circuits in addition to the bus interface unit (BIU) circuits. Each board includes one or more unusual event (UEV) detector circuits for signaling when the behavior of a stage is abnormal. The UEV fault signals from each board are collected by the BIU board. When a UEV fault is detected, the BIU board circuits prevent any further communications with the system bus and broadcasts the UEV fault signal to the other boards causing the different pipelined stages to emulate the completion of the instructions within the pipeline thereby flushing it. It is thereafter placed in a nonpipelined mode. Control circuits execute a UEV handler microcode routine which reads the contents of syndrome registers included on each board containing the UEV indicator states in addition to error signals into register file working locations. The UEV signal is then cleared enabling the BIU to resume communications with the system bus. A unique trap is constructed for signaling the operating system software if the UEV fault was external or internal to the CSS. Also, the contents of all working locations are written into an extended trap save area which enables the operating system to make its own independent decision as to whether the system's integrity has been jeopardized.

Abstract: A positive displacement pump (10) especially designed for home use comprises a crankcase housing (14) and a cylinder block (18) joined thereto, the cylinder block containing a cylindrical bore (20) whose longitudinal axis is at a predetermined angle relative to the longitudinal axis of the pump's drive shaft (30) journaled in the crankcase housing (14). A piston (52) having a central longitudinal bore (64) formed inward from one end thereof and which includes a timing window (66) extending through its side surface, is fitted into the cylindrical (20) bore and coupled to the drive shaft (30) by a pin (58) which is journaled in a spherical bearing (46). A suction port (22) is formed through the wall of the cylinder block on one side surface thereof and on the opposite side surface, 180° away, is a high pressure discharge port (24). When the pump is driven, the piston (52) both rotates and reciprocates causing the timing window (66) in the piston (52) to sweep by the inlet or suction port (22) where a charge of liquid at low pressure is allowed to enter the hollow piston (52). As the piston (52) rotates, the timing window (66) moves to a point where it is ultimately in line with the discharge port (24) when the piston (52) is at a top dead center position. By canting the pin (58) of the piston (52) relative to its longitudinal axis compensation for the unequal hydraulic forces acting in the transverse direction on the piston (52) results. An improved lubrication system (104) incorporating grease as the lubricant is also employed.

Abstract: Compound semiconductors belonging to groups III-V have a crystalline structure of the zinc blende type. Wafers sliced from a single crystal ingot on {100} planes have four cleavage planes. Two parallel cleavage planes are equivalent. But two cleavage planes perpendicular with each other are unequivalent. The etching speeds on the unequivalent cleavage planes are different from some pertinent etchant. 
     A difference of the mesa direction and the reverse-mesa direction along unequivalent cleavage planes exists in compound semiconductors unlike silicon semiconductor. 
     By etching process using a pertinent etchant natural anisotropic patterns appears on the rear side on a wafer to denote the mesa direction on the front surface by nature. Natural patterns have generally elongate shapes parallel with each other, resembling lines or ellipsoids. The direction of the longer side is the mesa direction on the front surface. Otherwise artificial parallel patterns can be formed on the rear surface to denote the mesa direction by photoetching process using photoresist and a mask with anisotropic pattern. This invention is especially useful for rectangular or square wafers which have not orientation flats on the peripheries.
