Abstract: PURPOSE:To enable a required size tubular or cylindrical fluororesin product to be obtained in highly dimensional precision without cutting work by a method wherein a fluororesin material is worked by sizing while it is being heated to a temperature higher than its melting point. CONSTITUTION:A retaining part 11a is formed on an outer peripheral surface of a piston 11. Further, a required caliber throttle part 12a is formed on an inner peripheral surface of a cylinder 12 which is freely movable in an axial direction of the piston 11.

Title: Data buffering system
Inventor: KASAI MINORU
IPC: G06F5/10
Filed: 1982-12-23
Abstract: PURPOSE:To perform reading asynchronously to and writing from a buffer of an RAM constitution by switching a read/write signal to an RAM from a write mode to a read mode and giving priority to a read request. CONSTITUTION:For example, a read request signal READ is inputted to an RAM control circuit 70 after writing operation starts and a write request and a read request overlap each other. In this case, when an effective read request signal READ is inputted, FFs 101 and 102 are set and an AND gate 104 outputs ''1''. Therefore, a multiplexer 50 switches an RAM-ADDRESS to the RAM10 from the output write address of an address counter 30 to the output read address of an address counter 40. Further, when the FF101 is set, an NOR gate 112 outputs ''0'', and consequently a read/write signal READ/WRITE' goes to ''1'' and the mode of access to the RAM10 is changed from the write mode to the read mode.
