Title: Molding of foam and mold for foam molding
Inventor: ONO TSUKASA
IPC: B29C45/26
Filed: 1990-03-07
Abstract: PURPOSE:To decrease an amt. of adhesion of a residue caused by decomposition of a blowing agent by heating the neighborhood of the end part of a cavity of a mold by means of a heater heating locally the part. from the time just before a resin is filled in this end part to several sec or min after the filling is finished and cooling thereafter. CONSTITUTION:When a foamable resin compsn. with an amt. which is smaller than the vol. of a mold cavity 1 is injected in the mold cavity 1 while the compsn. is melted, the compsn. fills in the mold cavity 1 and reaches the end part of the mold cavity while it is expanded. When electric current is energized in a heater 5 before the resin compsn. reaches the end part, the end part of the cavity 1 is heated and the temp. is elevated and a gas contg. a decomposed residue of a blowing agent generated from the resin compsn. is not cooled and therefore, the wall of the mold cavity 1 is not adhered with the residue and it is evacuated from a vent channel 4. When the resin is filled in the mold cavity 1, heating is stopped and the temp. of the mold is lowered by passing cold water through a cooling channel 3. When the resin is solidified, cooling is stopped and a product is taken out.

Title: Time monitoring device
Inventor: TSURUYA HIROSHI
IPC: G05B23/02
Filed: 1981-04-14
Abstract: PURPOSE:To prevent the increase in a monitoring time even if the number of events to be monitored increases, by a method wherein a time out memory and a means for addressing the time out memory are installed to carry out an access of each entery of the time out memory. CONSTITUTION:After a controller 2 receives the number of events to be monitored and a time out value from a host device 1, it adds them to set them at a selection resistor 6 for a time out recording part. Meanwhile, each time the controller 2 receives a signal generated at a given interval, it brings a content of a time resistor 5 to +1 which is stored in the resistor 5 and simultaneously is set at a resistor 6. In an AND circuit 8, a theoretical product is made on a content of a request resistor 7 and a content of a time out recording part 4 at each bit, and the result is stored in a result resistor 9. Then, the controller 2 reads the content of the resistor 9, and if 1 is given, it is decided from said number of the event that a time out is produced, and it is reported to the host device 1. This permits a monitoring time, spent in the increase in the number of events, to be prevented from increasing even if the number of the events to be monitored increases.
