Abstract: PURPOSE:To improve the durability of a solenoid valve and suppress noise and vibration by suppressing the switching operation of the solenoid valve in the nonoperation state of an operating lever by setting the insensitive band having a large value when the operating lever is in nonoperation state. CONSTITUTION:A setting means 16 such as a comparator for setting a plurality of insensitive bands having different values is installed between an operating lever and the comparators 12 and 13. When the setting means 16 detects from the signal of the operating lever that the operating lever is in nonoperation state, the setting means 16 outputs the set value delta1 for the insensitive band having a large value. Said set value delta1 is input into the comparators 12 and 13, and the range of the insensitive band is widened to suppress the switching operations of the solenoids 4a-7a of each solenoid valve. In case of other than the nonoperation state, the set value delta2 of the insensitive band having a small value is input into the comparators 12 and 13, and each solenoid valve is switching-operated with high precision.

Title: Treatment of resist
Inventor: SUZUKI SHINJI
IPC: H01L21/30
Filed: 1987-03-20
Abstract: PURPOSE:To prevent damage to a resist film caused by ultraviolet ray application by a method wherein the resist film is provided in a atmosphere under a reduced pressure and the ultraviolet rays are applied to it. CONSTITUTION:A wafer 5 coated with resist 4 is placed in an atmosphere whose pressure is reduced to lower than 20 Torr and an emitted light containing ultraviolet rays is applied to the resist 4. As the source of the emitted light, a high voltage mercury lamp 1, a low voltage mercury lamp, a metal vapor discharge lamp with a light emitting tube in which inert gas, halogen and metal are enclosed or a microwave excited electrodeless discharge lamp is employed. The intensity of the light application is low at first and gradually increased step by step. With this constitution, the outward exhalation of gas produced in the resist 4 is promoted so that the gas produced inside the resist 4 can be discharged outside quickly without filling up the inside of the resist 4. Therefore, the deformation of the resist film, foaming, or damage to the resist film 4 such as peeling off can be avoided.

Title: Forging method of outer race of universal joint
Inventor: OOMORI SHIYUNJI
IPC: B21K1/14
Filed: 1979-05-25
Abstract: PURPOSE:To make working easy and make material yield good by restraining the end face of the pressing surface to make the reduction ratio on the working side smaller than the stem part and pressing the same by determining the sequence of deformation at the time of forging. CONSTITUTION:When a heated circular cylindrical blank is put in a die 2 and the blank is pressed by advancing a punch 1, the blank is backward extruded upward and is forward extruded downward. When the blank deforms upward, it abuts against an outer punch 3 are receives the elastic restoring force of a spring 5. When  the deformation progresses, the blank retreats by being pushed by the outer punch  3 and contacts the shoulder part 1' of the punch 1, after which the outer punch 3  also presses the blank and the punch 1 and outer punch 3 advance by the stroke S.  At this time, the upper end part of the built-up thickness is crushed by receiving  the upsetting force of the outer punch 3, by which the formation of the thin-walled  part is assisted and the end face is made flat. After the hermetic closing at the top  end of the blank, the deformation becomes the stem part alone. This method makes  possible the volume production of the outer races of universal joints.
