Filed: 1988-11-11
Abstract: PURPOSE:To shorten the image up to the reception of a key input for a mode change by changing and accepting various modes without any new transfer process of a copying paper being transferred when the copying operation is stopped. CONSTITUTION:For example, a clear/stop key is turned on in a 3rd scan on a 1st document.

Title: Low pressure molding die
Inventor: NODA TOSHIO
IPC: B29C33/10
Filed: 1985-12-20
Abstract: PURPOSE:To obtain a semiconductor device with stable quality and high reliability by a method wherein a switching valve which is linked with an air vent is provided and air is exhausted out of a die through the switching valve. CONSTITUTION:A switching valve 8 is still closed and the air in a die is confined. A little molding resin 20 enters a cavity 34 through a gate 4 but is blocked by the pressure loss of the gate 4 and the air pressure in a cavity 5. Although the same pressure is applied to the molding resin in a runner 3, a flow resistance against the molding resin is much smaller than the flow resistance toward the gate 4 and as a result the molding resin 20 flows toward the runner 3 only. The air pressure in the die is gradually increased and, as a matter of fact, the injection pressure of the molding resin is increased. At that time, although it is easy for the molding resin to flow into a cavity close to a pot 2, as the air pressure is also increased, the flow is suppressed. At the time when it is completed to fill the runner with the molding resin, if the switching valve 8 is opened, the air is exhausted in the direction of evacuation in a short time by the pressure difference between the inside and the outside of the die. After that, all cavities are filled with molding resin.
