IPC: B29L31/34
Filed: 1985-08-31
Abstract: PURPOSE:To form a voidless molded article, by making the diameter of the upside of an about cylindrical tablet smaller than that of the bottom side. CONSTITUTION:A tablet 1 is constituted by making epoxy resin powder into the tablet in a state of a truncated cone and the diameter of the upside of the same is made smaller than that of the bottom side of the same. As for the tablet 1, though the bottom side is expanded and deformed slightly through concentration of pressure loading of a plunger 4 to the bottom side when pressure molding of the tablet 1 is performed by putting the tablet 1 into a pot 3, a part other than which is not deformed. In other words, the tablet 1 is molten from the bottom side while the same is kept at about the initial form as it is and fluidized. Therefore, involvement of air becomes hard to occur. As an air accumulator 5 can be made on the upper part of the truncated cone, whose part is communicated with the outside through a gap between the plunger 4 and inner circumferential surface of the pot 3, the air in the air accumulator 5 is dispersed outside easily at the time of pressurizing by the plunger 4. Therefore, the involvement of the air becomes extremely little.

Abstract: PURPOSE:To make the structure of the end of a tube simple and achieve high efficiency and a long service life by using a pellet which is a metal substrate having a mercury alloy in a caved part formed in at least a part of it as an electrode and putting a metal near the mercury alloy. CONSTITUTION:Pellets 15, 16 which are metal substrates having a mercury alloy 13 in a caved part formed in at least parts of them are used as electrodes and a metal is put near the mercury alloy 13. The pellets 15, 16 can thus contain a large amount of mercury. Since heat generated in the electrode parts 1, 2 is transmitted to the end part of a tube through the metal rod 7, temperature of the electrodes is lowered and long lives of the electrodes are obtained. If the metal is made a metal rod, the structure of the electrodes becomes simple and glow enters in the gap formed between the caved parts of the pellets 15, 16 and the metal rod 7 and voltage decrease of a cathode is lowered owing to, so called hollow cathode effect and cathode loss is lowered. As a result, a low pressure discharge lamp having high efficiency is obtained.
