Title: Pearl for jewelry and working method therefor
Inventor: SAKATA MINETO
IPC: A44C17/00
Filed: 1998-05-22
Abstract: PROBLEM TO BE SOLVED: To remarkably reduce limitations in the design of jewelry by forming a hole at a position not piercing through the core of a pearl. SOLUTION: Concerning the pearl for jewelry prepared by forming a pearl layer 3 around a core 2, a hole 11 not piercing through the core 2 is formed on the pearl layer 3 and the inside of the pearl layer 3 is filled with resins 12. Thus, since a gap between the surface of the core 2 and the pearl layer 3 is reinforced by the resins 12, even in the case of a hole 11 formed at the position not piercing through the core 2 while originally the pearl layer 3 is floated from the surface of the core 2, there is no danger that strength is lowered. Therefore, since the hole 11 can be formed at the position out of the core 2, the limitations in the design of jewelry can be remarkably reduced.

IPC: H01L27/10
Filed: 1989-06-19
Abstract: PURPOSE:To improve speed for a read only IC memory by arranging Y decode signal wiring between the elements of a logically constituted Y selector and arranging the high-order Y selector element closely to a sense amplifier load circuit. CONSTITUTION:When the sense amplifier load of a memory cell array is con nected by the Y selector in the AND constitution of two steps, a Y selector 2 in the second step is arranged close to a sense amplifier 1 and Y decode signal wirings 3 and 4 are arranged between the selector 2 and a Y selector 5 in the first step. Then, output data signal connecting wiring 7 is connected between the selectors 2 and 5 so as to cross the wirings 3 and 4. Thus, wiring capacity for a part crossing the wirings 3 and 4 is attached to a connecting point between the selectors 2 and 5. Wiring capacity to be attached to the other selector in the second step is not always the capacity to be driven by the sense amplifier load circuit 1 separated by the Y selector. Accordingly, the wiring can be shortened between the sense amplifier load and Y selector and the speed for the read only IC memory is improved.

When this dividing process is through, the number of divisions is obtained so that the cutting pitch is maximum for divided areas PGi and PG2 respectively. At the same time, the segments L11-L16 and L21-L23 connecting the centroids W1 and W2 of both divided areas are divided by the decided number of divisions. Then the tool paths are decided in consideration of the dividing points of those divided areas.
