Title: Image forming device
Inventor: TAKADA AKIHIRO
IPC: G03G21/00
Filed: 1989-10-20
Abstract: PURPOSE:To prevent damage to an original and to improve workability of copying by first stopping a carrying device when paper jamming of a transfer paper is detected during an image forming action, and then stopping an original traveling device after the completion of the ejection of the original is detected. CONSTITUTION:When jamming (paper jamming) is detected by carrying switches 20a and 20b during the image forming action, the carrying device is stopped and the carrying of the transfer paper is stopped, and next when ejecting completion of the original from the original traveling device 22 and 23 is detected by an ejecting switch 25a, the original traveling devices 22 and 23 are stopped by the control device. Therefore, even when jamming is generated, the action of the original traveling device is continued until the original is ejected. Thus, since at the time of generation of jamming, the originals from the original traveling devices 22 and 23 are always ejected, the original is never damaged and the next image forming action can be carried out smoothly.

Title: Double feed type single cavity molding equipment
Inventor: HARARUDO HANSU SHIYUMITSUTO
IPC: B29C45/28
Filed: 1987-10-29
Abstract: This invention relates to a manifold housing for a valve gated single cavity injection molding system. The heated manifold housing (14) has a dome portion (40) and a base portion (38) which is secured to a heated nozzle (10) with aligned central bores (22, 42) through which the valve pin (44) extends. Hydraulic actuating mechanism is mounted inside the manifold housing to reciprocate the valve pin (44) between open and closed positions. The melt duct (52) in the manifold branches from a central inlet (20) into two separate arms (54, 56) with smoothly curved bends which extend to join the central bore (42) on opposite sides of the valve pin (44). Providing two streams of melt which meet at the valve pin avoids the problem of streaking and slow melt flow on one side of the valve pin.
