Abstract: PURPOSE:To prevent the resonance generation of the hydraulic pressure variation by constituting a hydraulic passage for supplying hydraulic pressure from a hydraulic pressure generating source to a brake cylinder to be selected according to the traveling state of a vehicle by a selector valve and a parallel hydraulic passage. CONSTITUTION:The hydraulic pressure generated in a master cylinder 1 is supplied into the calipers 6 and 7 of the right and left front wheels and the calipers 8 and 9 of the right and left rear wheels through the hydraulic passages 3 - 5, and a long partial flow hydraulic passage 21 is branching-connected through a selector valve 20 into a hydraulic passage 4, and the other edge is directly connected to the hydraulic passage 4 on the master cylinder side 1. In the state where a brake pedal 2 is operated, if the car speed is within a prescribed range (about 100 - 120km/h) and the brake power G is less than 0.2G, the selector valve 20 is turned ON, and in other traveling state, the selector valve 20 is turned OFF. Therefore, the resonance of the hydraulic vibration is prevented by selecting the length of the hydraulic passage used in each operation state.

Title: Manufacture of ceramic pellet for nuclear fuel
Inventor: TOKAI KAZUTOSHI
IPC: G21C3/62
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a ceramic pellet where tungsten is widely dispersed by tusing a raw material powder containing a mixed powder of UO2 and WO3 as a forming body, heating the sintered body of a solid solution being obtained by heating in a reduction atmosphere, and depositing tungsten (W). SOLUTION: After a raw material powder containing a mixed powder of UO2 and WO3 is formed into a pellet-shaped forming body, it is heated in a slight oxidation atmosphere. As a result, UO2 becomes UO2- X(0<X<0.2a ) and reacts with WO3 at a heating temperature of 700 deg.C or higher, thus forming solid solutions (UWO6 , and UW3 O12 ). The solid solutions form a liquid phase by heating again for performing liquid-phase diffusion. Since a sintering phenomenon progresses faster in the liquid phase, WO6 and UW3 O12 are diffused uniformly by a heating process, thus obtaining a sintered body with sufficiently progressed sintering. When the sintered body is heated in a reduction atmosphere, W is deposited by reduction, thus resulting in UO2 or UO2 +W, so that a ceramic pellet containing UO2 where sintering has fully progressed and W that has uniformly diffused into the pellet.

Title: Method of adjusting electron beam exposure apparatus
Inventor: ISHIZUKA TOSHIHIRO
IPC: H01J37/304
Filed: 1981-06-18
Abstract: PURPOSE:To improve working efficiency and to increase work efficiency by a method wherein an electron beam is scanned in two directions crossing a mark on a sample and then a focus and astigmatism are corrected using a detected electron signal attained on a CRT. CONSTITUTION:A mark 13 placed on the surface of an exposed sample 12 is used to carry out adjustment. The mark 13 is formed of, for example, an Au film in a rectangulr pattern which has side faces in coincidence with the X and Y direction, respectively. An electron beam is alternately deflected and scanned at a conatant speed in the X and Y direction in an area near the Au pattern, and reflected electrons are detected by a reflected electron detector 11. Thus detected signal is displayed on a CRT17 through an amplifier 16. Since the surface of the Au pattern reflects larger number of electrons and the surface of a silicon substrate reflects smaller number of electrons, there occurs a difference between both signal levels. Thus, it becomes possible to easily correct the focus and astigmatism for each exposed sample and also to improve exposure accuracy for patterning.

A piston 23 is thereby reset with light force. When the crank arm 13 reaches the bottom dead center, a bottom dead center sensor 42 detects this, and the top-bottom dead center reacting valve D is switched to open the air passage 29.
