Title: Simulation method for flatness
Inventor: HAYASHIDE YOSHIO
IPC: G06F19/00
Filed: 1995-06-21
Abstract: PURPOSE: To carry out simulation without being limited by a pattern configuration of a wiring layer. CONSTITUTION: A surface of a semiconductor device is divided into a number of cells. For each cell 111, a polishing velocity (r) of the cell 111 is calculated at r=r0 .g/d to an occupation rate (d) of a projection part 301 inside the cell 111. A constant (r0 ) is a polishing velocity when all the cells are flat and a coefficient (g) is given at g=1+c.(a height of the cell 111 - a height of a peripheral cell) by using a positive constant (c). A height at each time is updated as a height at the next time by using the polishing velocity (r). Then a polishing velocity at the next time is calculated by using an updated height of each cell. The above treatment is repeated.  Since a polishing velocity is thereby calculated by using an occupation rate of a projection part inside each cell and a height of each cell at each time, there is no limit on a pattern configuration of a wiring layer and simulation can be performed for a device of any pattern configuration.

Title: Control system for cache memory
Inventor: SHINANO JUNZO
IPC: G06F12/08
Filed: 1987-06-22
Abstract: PURPOSE:To perform the instruction executing processes of a CPU within a block transfer period by providing a means which transfers the unit data which is under block transfer to a cache memory from a main memory to the CPU. CONSTITUTION:In case a data fetch request is received from a CPU 1 and no request data is stored in a cache memory 2, the data on a request address is stored in a register 7 and the block transfer is started to the memory 2 from a main memory 3 via a memory has 5. The unit data on the bus 5 which is under the block transfer is stored in a buffer register 8 along with the address of said data. A comparator 9 compares the address of the register 7a with the contents of the register 8 by a signal 11 received from the memory 2 and showing a block transfer state every time the unit data is transferred. When the coincidence is obtained from aid comparison, the data is sent to the CPU 1 via a unidirectional buffer 10. The CPU 1 continues its processing with the received data. Thus the block loading and instruction executing jobs are carried out in parallel with each other and therefore the throughput is improved.

     CONSTITUTION: A bundle of unidirectionally extending fibers F is provided in the body 1 of a connecting rod between its large end 2 and small end 3 so that the bundle is located almost in the middle of the thickness L of the rod along the length of a wrist pin. The end Fa of the bundle of fibers at the small end 3 is divided into two around a wrist pin hole 4 so that the rod part around the hole is reinforced with the fibers. Light alloy is filled as a matrix M on the fibers F. When the thickness L along the length of the wrist pin  and the diameter D of the wrist pin hole 4 are related to each other as L/D=1.0W35, the sum of the depths of the chamfered sections 5 on both the edges around the hole 4 or the sum of the radii of curvature of the chamfered sections is set equal to 10W25% of the thickness L.
