Abstract:
A microcomputer includes an instruction decoder and a program counter. The instruction decoder decodes fetched instructions and outputs a control signal ordering execution of the fetched instruction. The control signal from the instruction decoder includes a component controlling fetch cycles which triggers a fetch cycle at the beginning of each instruction cycle to fetch the operand for the instruction currently being executed and midway through each instruction cycle to fetch the OP code for the next instruction. The program counter is responsive to the triggering of each fetch cycle to increment its counter value so as to keep the counter value consistent with the address being accessed in each fetch cycle.
Abstract:
Wafers are previously positioned so that the wafer orientation flat is oriented in a particular direction. A transporting means then moves and places the previously positioned wafer on a bonding stage where bumps are formed on the wafer by means of a bonding head. The transporting means has a sensor for detecting the position of the orientation flat of a wafer on the bonding stage from a position above the bonding stage, thereby avoiding the adverse effects of heat from the bonding stage during orientation flat detection.
Abstract:
A base member obtained by cutting a cylindrical body having a center axial line at a maximum asymmetric angle &agr;0 with respect to a plane orthogonal to the center axial line of cylindrical body is prepared. Next, the thus obtained ellipsoidal asymmetric cut surface of the base member is shaped along a peripheral surface of an imaginary cylindrical body having a radius R0, into an asymmetric cut curved-surface. Then, a monochromator Si crystal is bonded to the asymmetric cut curved-surface of the base member. Both the asymmetric angle and the radius of curvature for a desired wavelength within a wide wavelength range can be simultaneously tuned only by the &phgr;-axis rotation.
Abstract:
It relates to a quinazoline compound useful as a medicine exhibiting an inhibitory action on calmodulin-dependent cGMP-PDE.A quinazoline compound represented by the general formula (I) or a pharmacologically acceptable salt thereof: ##STR1## (wherein R.sup.1, R.sup.2, R.sup.3, R.sup.4 and R.sup.5 may be the same or different from each other and each represents a hydrogen atom, a lower alkyl group or the like; and R.sup.6 and R.sup.7 may be the same or different from each other and each represents a hydrogen atom, a carboxyl alkyl group or the like).
Abstract:
To speed up data transfer, one embodiment of the invention features a transmission gate arrangement which pre-charges and transfers data in internal and external buses with the same timing and which further initializes the internal bus and a device such as an ALU, every bus cycle. A second embodiment speeds the data transfer in the buses by providing two data transfer paths through the interconnected buses and reducing the combined resistances of the internal and external buses.
Abstract:
A microcomputer universal package has testing terminals and switching circuitry for selecting first and second operations. In the first operation, as an evaluator type, a test device is connected to the testing terminals of the package. In the second operation, as a piggyback type, a rewritable ROM (EPROM) is connected to the testing terminals of the package. The testing terminals are automatically switched for the particular operation by the switching circuitry. Accordingly, the same device can be used as the evaluator type chip and the piggyback-type chip, which reduces the time and the cost of developing the program. In addition, since the piggyback-type chip, the evaluator-type chip, and a mask-type ROM chip can be constructed with the same pin arrangement, the program can be evaluated by the evaluator-type chip in the mask-type ROM mounting board that becomes the final product without requiring an interface board.
