Title: Compressor controller for vehicle
Inventor: HAJIKANO TSUYOSHI
IPC: B61D19/02
Filed: 1995-02-16
Abstract: PURPOSE: To promote a low noise typification as securing the extent of safety by installing two compressors and also each electric motor driving these comprossors separately, and operating these motors in alternately switching them according to pressure in a tank where compresssed air is stored. CONSTITUTION: When compressed air in a tank is wasted with the travel of a vehicle, a comtact 34a of at least one side pressure governor 34 is closed. 'Therefore a coil 60 of a switching relay 54 is magnetized and thereby two contacts 56 and 58 are switched. Subsequently voltage is impressed on a first time limit relay 82 via a contact 62a of a first release switch 62 and a contact 16a of a low voltage detector 16. Accordingly a coil 78 of a first relay 66 is magnetized and a contact 70 is closed, whereby a coil 74 is magnetized and a first electric motor 4 is thus driven. In consequence, a first compressor is operated and the caressed air is fed to the tank. When pressure in the tank goes up and comes to the upper limit value, the contact 34a of the first pressure governor 34 is opened, so any drive of the first electric motor 4 is stopped.

Title: Pattern formation and device therefor
Inventor: OKUMURA MASAHIDE
IPC: G03F7/20
Filed: 1987-02-12
Abstract: PURPOSE:To form a fine pattern at high speed and with high precision by a method wherein each merit of an electron beam lithography means and a light exposing (transfer, projection and lithography) means is utilized to bear roles in common. CONSTITUTION:A light exposure ends instantaneously, but as a single stroke drawing technique is used for an electron beam lithography, it takes a long time to form a pattern. Accordingly, if fine patterns (electron beam lithography patterns) 1 and 2 only are lithographed with an electron beam, a pattern can be formed in a very short time and if a light exposure and an electron beam lithography are performed in parallel, a pattern can be formed in higher speed. For example, by using a combined device of a lithography equipment using a field emission type electron gun and a projection type exposing device, a pattern forming region is simultaneously lithographed and exposed at the same time as the pattern is formed.

Title: Negative type photoresist composition
Inventor: TODOKO MASAAKI
IPC: H01L21/027
Filed: 1990-02-09
Abstract: PURPOSE:To make improvement in transparency to UV light and far UV light and definition by incorporating an alkali-soluble resin contg. an arom. group, and ammonia salt having the reactive group and a compd. having a photoreactive group or reactive group as essential components into the above compsn. CONSTITUTION:An alkyl compd. of 5 to 30C contg. >=1 azide groups or an alkyl compd. of 5 to 30C contg. >=1 epoxy group or double bonds and the alkali-soluble resin contg. the arom. group are incorporated as the essential components into this compsn. The dissolution inhibiting ability of the ammonium salt depends on the structure of this salt; the dissolution inhibiting ability is high as the chain length of the alkyl group is longer, i.e. as the number of the carbon atoms is larger. The dissolution inhibiting ability is higher as the number of the long chain alkyl groups is larger. Further, exposed parts are made insoluble in an alkaline developing soln. by convering the short chain alkyl ammonium salt to a long-chain alkyl ammonium salt by exposing in the case of the short chain of the alkyl group of the alkyl ammonium salt. Unexposed parts are not changed in the solubility and patterning is possible. The improvement in the transparency to the UV light and far UV light and the definition is made in this way.
