Title: Apparatus and method for exposing charged particle beam
Inventor: YAMADA AKIO
IPC: G21K5/04
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To independently inspect elements of an exposure apparatus so as to shorten preparing processes and enhance an availability factor by forming reference marks of different reflection coefficients on sample screens, detecting variations in strength of a reflection electron and a sample current, and setting a change coefficient for correction. SOLUTION: An input setter 65 sets input data in registers 62, 64, so that a converter and an amplifier 60a drive a beam deflector DEF inside an exposure apparatus, to change a position of an electron beam EB. When reference marks having different reflection coefficients are formed at a sample screen and a stage screen, respectively, variations in intensity of a reflection electron and strength of a sample current can be detected via an analog/digital converter and amplifiers 67, 68. The input setter 65 detects response characteristics of the variations in strength by the use of a response signal analyzer 66, and sets a change coefficient for correction and conversion with respect to a pattern correcting unit 15 in the case of an allowable value or higher.  Consequently, elements of the exposure apparatus can be inspected independently, thus shortening preparing processes and enhancing an availability factor.

Abstract: PROBLEM TO BE SOLVED: To cooling a high temperature parts even if pressure is raised to a high value so as to suppress raising of steam pressure by changing a control signal of temperature control means into a control signal on the basis of pressure of steam when pressure of steam is raised to a high temperature. SOLUTION: When an abnormal condition of some kind is generated, for example, a failure is generated on an intermediate pressure drum pressure control valve 11 or a control circuit, and an output of a pressure detector 13 of an intermediate pressure drum is raised to a high value, its output is converted into a control signal higher than a control signal 17S from a temperature controller 17 through a pressure controller 19, and is supplied to a high value selector 18. As a result, the selector 18 is switched and the control signal 19S is supplied to a temperature control valve 12. The valve 12 is opened wider according to an input, and a steam flow rate is increased. It is thus possible to cool a high temperature parts 8, and it is also possible to suppress raising of steam pressure.

Title: Semiconductor device
Inventor: SONOBE KAORU
IPC: H01L23/50
Filed: 1987-04-30
Abstract: PURPOSE:To alleviate a thermal impact stress at the time of mounting a printed substrate by bonding a stress alleviating member made of a shape memory alloy having specific transformation characteristic on the rear face of a semiconductor element placing base. CONSTITUTION:A semiconductor element 1 is secured onto the upper face of a semiconductor element placing base 3. A stress alleviating member 7 made of shape memory alloy, such as Au-Cd alloy having thermal elastic martensite transformation and stress induction martensite variation characteristic is secured to the rear of the base 3. The Au-Cd alloy which contains 46.5-50 at% Cd has its martensite transformation point at approx. 58 deg.C. Since the transformation temperature hysteresis width is 30 deg.C or less, when the member 7 resin-sealed at approx. 170 deg.C is cooled, a thermal elastic martensite transformation occurs, a volumetric change of 0.4% or less occurs, and it is softened. Thereafter, since it becomes high temperature at the time of mounting by flowing solder to a printed substrate, the member 7 is reversely transformed to absorb the thermal impact stresses of the base 3 and the resin 8, thereby alleviating the stress of the whole package.

IPC: B60K17/10
Filed: 1994-05-23
Abstract: PURPOSE:To prevent the generation of rotational dispersion to left and right axles so as to improve straight advance stability by connecting one vertical input shaft interlockingly to the pump shafts of left and right hydraulic pumps through a drive train. CONSTITUTION:Power from an engine is transmitted to a pulley 25 on one input shaft 24 and then transmitted to left and right pump shafts 3L, 3R from the input shaft 24 through a drive train in a housing so as to drive left and right hydraulic pumps PL, PR at the same rotating speed. Hydraulic motors are respectively driven by oil pressure from the respective hydraulic pumps PL, PR so as to be able to perform the continuously variable speed change of left and right axles. Pressure oil from a charge pump driven by either one of the left and right pump shafts is simultaneously fed to closed circuits for connecting the respective left and right hydraulic pumps to the respective left and right hydraulic motors. Since the left and right hydraulic pumps are driven in common, the generation of dispersion to the left and right axles is prevented so as to improve straight line stability.

Title: Artificial leg with extension auxiliary mechanism
Inventor: OKUDA MASAHIKO
IPC: A61F2/64
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To provide an artificial leg with an extension auxiliary mechanism generating extension torque only when the angle of the bending of the curve of a knee is small. SOLUTION: The knee joint 80 of a thigh artificial leg 170 is multiaxial and a front link 130 and a rear link 150 constitute a constrained chain with a thigh member 110 and a crus member 120. The extension auxiliary mechanism 1100 including a compression spring is supported between the member 120 and the link 150. The extension torque by the mechanism 1100 is determined by the product of force accompanying the deformation of the compression spring and a distance from the operating line of the force to the rotating center of the link 150. In this case, at a stage where the curving angle of the knee exceeds 15, the axis of the compression spring forms nearly a straight line with a connecting part 170 of the link 150 and the number 120, thereby a distance related with the extension torque is made nearly zero to make the extension torque itself nearly zero.
