Filed: 1986-08-19
Abstract: PURPOSE:To make it possible to eliminate the necessity of readjustment of the amount of lift, by inserting a valve opening pressure adjusting screw, threadedly in the inside of a lift amount adjusting screw. CONSTITUTION:The amount of lift of a needle valve 2 is limited between the front end of a hollow cylindrical lift amount adjusting screw 5 fitted threadedly in a nozzle body 1 and a stopper 7 formed on the needle valve 2. Further, a spring 3 is stored in the inside of the lift amount adjusting screw 5, and a valve opening pressure adjusting screw 4 is threadedly inserted therein. With this arrangement, if it is required that the valve opening pressure is readjusted due to fatigue or the like of the spring, the valve opening pressure adjusting screw 4 is adjusted. At this stage, since the lift amount screw 5 is not moved, the valve opening pressure alone may be adjusted, thereby it is possible to eliminate the necessity of readjustment of the lift amount.

Title: Energy-sensitive resist material and device manufacturing process using said resist material
Inventor: DEIBUITSUDO ANTON MIKUSON
IPC: G03F7/30
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To provide an energy sensitive resist material and a device manufacturing process using this material. SOLUTION: The energy sensitive resist material which is a combination of a base body polymer and a condition agent polymer is formed on a substrate. The condition agent polymer and the base body polymer are phase compatible. The condition agent polymer has an average mol.wt. of about 5,000 to about 500,000g/mol and some extent of a polymer chain is terminated at a halogen group. The resist material is exposed in a pattern form to radiations, by which the latent images of the patterns are formed in the resist material. Energy depolymerizes the condition agent polymer. The condition agent polymer has substantially lower solubility in a developer for developing the patterns formed in a resist than the base body polymer. Then, if the resist material is of a positive type, the parts exposed to the radiations are substantially more soluble in the developer than the non-exposed parts.  The exposed parts of the resist material are selectively removed.
