Filed: 1989-02-28
Abstract: PURPOSE:To avoid a local increase in the congestion degree of wiring and to contrive the improvement of the connection rate of connecting pins by a method wherein the sum of the number of the connecting pins and the number of equivalent pins in a region available for arrangement in every lattice is uniformly distributed in the unit of a pin box on a chip. CONSTITUTION:All cells 12 on a chip are deployed at a forbidden region 10 along with their connecting pins 9 and the region 10 is represented by the virtual number of the connecting pins corresponding to its area. Then, the chip is divided in a lattice type, a region available for arrangement in every lattice 3 is estimated and the number of equivalent pins of the sum of the number of the connecting pins and the number of equivalent pins, which are included in each lattice, is found. At this time, the area of the region 10 is evaluated in the unit of the number of wiring grids, which ara decided by vertical wiring lattices 7 and horizontal wiring lattices 6, and this area is thought to be the number of the equivalent pins. A decision on the moving destinations of the cells 12 is limited in the adjacent 8 lattices. By this series of steps, the distribution of the equivalent pins can be made uniform in every lattice.

Title: Optical information detector
Inventor: MORIMOTO YASUAKI
IPC: G02B7/00
Filed: 1983-03-22
Abstract: PURPOSE:To perform both focusing and tracking quite independently of each othr in order to eliminate higher resonance by shifting a means which converts a light source or the light outputted from said light source into a plane waves in the direction vertical to an optical axis. CONSTITUTION:The semiconductor laser light 1 made incident to a collimator lens 2 is made incident to an objective lens 5 in the form of parallel plane wave to form a spot on an optical axis on a disk 6. The light emitting point of the light 1 or the lens 2 is set with a shift from the optical axis. Under such condition, the light beam outputted from the lens 2 advances in parallel but not parallel to the optical axis. Therefore, a spot is formed at a position on the disk 6 with a shift from the optical axis. In such a way, the focusing can be separated completely from the tracking by applying the function of a tracking actuator to the light 1. In such a way, higher resonance is prevented.

IPC: G06F7/38
Filed: 1989-02-27
Abstract: PURPOSE:To prevent sign inversion of data to continue correct operation by detecting overflow beyond an overflow margin by a second overflow detecting circuit to correct the operation result from a accumulator. CONSTITUTION:Input data X1 and an operation result X2 of the preceding operation cycle are inputted to an arithmetic logic unit (ALU) 2, and the ALU 2 operates these data, and the operation result is stored in an accumulator 3, and stored contents are outputted to an overflow detecting circuit 4, a sign flag detecting circuit 5, and a superoverflow detecting circuit 6. When the output value of the accumulator 3 is in the overflow state and the sign flag is changed by the operation in the ALU 2, the superoverflow detecting circuit 6 decides the occurrence of overflow beyond the overflow margin and gives data, where the output value of the accumulator 3 is corrected, to a input 7 of the ALU 2. Thus, the sign inversion phenomenon of data is prevented to always obtain correct operation results.

Further, a suction means 5015 for sucking ink in the cap member 5022 of a recording head is provided to suck and recover ink in the recording head. In this case, a suction rate that is a forced discharge rate is made greater than the internal volume throughout the ink flow path in an ink jet unit IJU being the recording head. As a result, ink passes through the ink flow path and is reliably supplied up to a nozzle part 401.

Abstract: PURPOSE:To lower the rate of releasing gaseous FP without increasing the interaction with a cladding pipe by packing raw material powder of high activity and raw material powder of low activity respectively into the diametral central part and diametral outer peripheral part in a press mold. CONSTITUTION:The raw material powder for the nuclear fuel to be used in this method is essentially composed of UO2 powder. The UO2 powder having >=3m<2>/g specific surface area, more preferably 5 to 15m<2>/g is used as the UO2 powder of the high activity. On the other hand, the UO2 powder having <=3m<2>/g, more preferably 1 to 2m<2>/g is used as the UO2 powder of the low activity. While the diametral central part 1 is constituted of the structure having the excellent holdability of the gaseous FP and a large crystal grain size, the outer peripheral part 2 is constituted of the structure having a relatively high creep speed and the small crystal grain size, by which the unclear fuel pellet is consti tuted. The rate of releasing the gaseous FP is lowered without increasing the interaction with the cladding pipe at the time of irradiation.

Abstract: PROBLEM TO BE SOLVED: To shorten the time when an OA equipments is occupied and to improve the processing efficiency and convenience in a network system by transferring the image data and various types of information between the OA equipment and a terminal equipment via a work space means. SOLUTION: A user notifies a general controller 108 of his name and password via his own terminal equipment. Then the controller 108 collates the name and password of the user with the registered contents and notifies the user of this collation result. Thus the access right is permitted only to the user whose name and password are registered. If the coincidence of collation is confirmed, the controller 108 inputs the reading conditions registered previously from a work space storage 106a via a work station 102a and sets a reading condition list to an OA equipment. Then the image data are transferred between the OA equipment and the terminal equipment via the controller 108 and a storage 106a (work station 102a).
