Title: Injection molding nozzle
Inventor: KATO SHUNICHI
IPC: B29C45/23
Filed: 1990-02-16
Abstract: PURPOSE:To mold an item insusceptible to deterioration of an oxygen barrier layer, by a construction wherein an opening part provided for a fifth restriction chamber for communication with a resin passage hole is extended in a retracting direction of a rod form valve so as to make communication between the fifth restriction chamber with the resin passage hole, and a front end face of the valve is formed as a tapered surface recessed in a retracting direction of the valve. CONSTITUTION:A front end face 28a of a rod form valve 28 is a tapered surface recessed to the inner side of the valve 28, namely, in a retracting direction of the valve 28. When only a resin in a fifth restriction chamber 16 is fed into a resin passage hole 27 in a final step, the resin flows through a resin passage 29 and via a front end part of the valve 28 into the passage hole 27 in the manner of spreading along the reverse-tapered shape of the front end part. Consequently, a resin with oxygen barrier qualities staying at the front end part of the valve 28 or the like is flushed away, and the oxygen-barrier resin or the like is completely pushed into a cavity 3 via a sprue hole 4. A front end part 29a of the passage 29 is normally open into the passage hole 27. A rear end part 29b of the passage 29 extends to such a position as to make communication between the fifth restriction chamber 16 and the passage hole 27 when the front end part of the valve 28 interrupts the communication between a first restriction chamber 12 and the passage hole 27.

Abstract: PURPOSE:To make it possible to use a memory unit without design change even if the memory unit has a fixed fault, by making it possible to designate freely relationship between write information and read information. CONSTITUTION:Write amplifier 5 writes the antilogarithm of inputted write information WD onto memory cell array 1 as it is or converts the antilograrithm to a complement to write it onto memory cell array 1 on a basis of write switching signal WS. Read amplifier 6 reads the antilogarithm of read information RD read out from array 1 as it is or converts the antilogarithm to a complement to read it on a basis of read switching signal RS. In case that the memory element used in a RAM memory unit designed already is substituted by a memory element where relationship between antilogarithm and complement is opposite, it is sufficient if one of signals WS and RS supplied from switches 7 and 8 is set oppositely and outputted. If a fixed fault occurs when the memory unit is used as a ROM, signals WS and RS are switched together and supplied, so that the memory unit can be utilized effectively even for fault.
