Title: Radiation sensitive resin composition
Inventor: TAKADA HIDEKAZU
IPC: G03F7/004
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To obtain the radiation sensitive resin composition high in sensitivity and superior in the pattern profile to be formed and suitably usable as a resist for forming large scale integrated circuits by incorporating an alkali-soluble resin and a phenol compound selected from specified compounds and a 1,2- quinonediazido compound. SOLUTION: The radiation sensitive resin composition contains the alkali- soluble resin and the phenol compound selected from the compounds represented by formulae I-III and the like and the 1,2-quinonediazido compound. In formulae I-III, each of R1 -R3 is, independently, an H atom or astraight or branched alkyl group optionally having a halogenated substituent or an alkoxy or alkenyl or hydroxyl group. A preferable content of the phenol compound is a 1-100 weight % of the alkali-soluble resin. This radiation sensitive resin composition effectively restrains occurrence of scum and provides superior developability and high resolution and high sensitivity and superior pattern profiles to be required at the time of manufacturing the large scale integrated circuits.

Title: Brake liquid pressure control valve
Inventor: AZUMA TOMIZO
IPC: B60T8/26
Filed: 1986-12-20
Abstract: PURPOSE:To enable execution of brake even when the one of a pair of brake systems is damaged, by a method wherein when a valve member is moved by a passage closing regulating member during axial movement of a plunger, a stepped piston is mounted movably in a direction in which a valve seat can be seated on the valve member. CONSTITUTION:When the one system is damaged, a liquid pressure is lowered, and a plunger 15 is moved. In which case, a passage closing regulating member 22 is moved along a stepped part 15a of the plunger 15 in a direction, in which it is separated from a stepped piston 18, through the force of a coil spring 29. In this case, when a brake pedal is stepped on with a force, the stepped piston 18 of the other system is moved in the direction of a valve member 21 by means of a difference in a pressure collecting area therebetween. An outer piston 32 is stopped at an upper surface 17a of a chamber 17, but only an inner piston 33 is moved, a valve seat 20 formed to the inner piston is seated on the valve member 21 to close a passage 19, resulting in disconnection of the feed of a liquid pressure. The valve member 21 and the valve seat 20 are repeatedly separated from and seat to each other like ordinary hydraulic control working to control a liquid pressure to a rear wheel brake.

Title: Error rate measurement method
Inventor: SUGIMOTO DAIKI
IPC: H04J13/00
Filed: 1996-11-15
Abstract: PROBLEM TO BE SOLVED: To provide the error rate measurement method in which a bit error rate is easily measured without taking frame synchronization. SOLUTION: At first a spread spectrum code pch PN is multiplexed synchronously with a transmission pilot signal on a reception signal. Then a traffic symbol demodulation circuit 4 demodulates the pilot signal itself. Since the pilot channel conducts the same processing as spreading data of 1 or 0 by a spread code of the pilot signal at all times, a bit error rate is measured by calculating a ratio of 1s and 0s by demodulating the channel.
