Title: Forming method of dam for preventing outflow of sealing resin in semiconductor element
Inventor: INABA TOYOKAZU
IPC: H01L23/28
Filed: 1986-09-03
Abstract: PURPOSE:To simplify the process, by using an adhesive resin, in which a thermally expanding material is kneaded, forming a dam at the stage of a circuit substrate, thereby omitting the mounting of a dam part at the mounting step of a semiconductor element. CONSTITUTION:A resist resin 12, in which thermally expanding microcapsules are kneaded, is applied to a specified position on a circuit substrate 11 by a printing method. The resist resin 12 is heated and hardened. Then, the applied part is expanded and hardened. Thus an upheaved dam 13 is formed. The circuit substrate, which has the dam formed in this way, is used for mounting a semiconductor element. After the semiconductor element 14 is mounted, a packaging resin 13 is injected. The packaging resin is blocked by the dam 15, and a packaging can be formed in a specified shape. Since the dam is formed in the manufacturing stage of the circuit substrate, a cumbersome step for mounting the dam at the later stage can be avoided.

Title: Evaporator
Inventor: NOMURA OSAMU
IPC: C02F1/04
Filed: 1981-12-22
Abstract: PURPOSE:To decrease the discharging rate of steam, to prevent the decrease in efficiency, and to make the suction rate of a steam bleeder adequate by providing plural gas venting ports of different heights on the heating side of an evaporator, and bleeding steam mainly from the gas venting port which is lowest above the liquid level. CONSTITUTION:In order to set the rate of evaporation (evaporating capacity) of an evaporator 1 at a prescribed value, a water level is set in a control mechanism 8. In the stage of changing the evaporating capacity of the evaporator 1, the level of the condensed liquid is changed to comply with load capacity by the mechanism 8. In this time, gas vent valves 21, 21', 21'' are controlled by the liquid level control mechanism in the mechanism 8. For example, in the case of raising the level of the condensed liquid from the lowermost position, the gas vent valves that submerge the liquid level are closed so that the gas vent valves which are lowest above the liquid level are always opened. Since there is some air that is blown upward in the evaporator 1 and arrives at the upper part, this air is bled through a gas vent port 20.
