Title: Finite element method
Inventor: HATTA SHINICHIRO
IPC: G06F17/50
Filed: 1991-03-26
Abstract: PURPOSE:To facilitate an analysis of a finite element method when an energy functional is not expressed in a secondary form of an unknown number. CONSTITUTION:When the nodal point value is obtained as an unknown number with division of an analysis area, a simultaneous differential equation or difference equation is produced for the attenuated vibration including an energy functional expressed in an optional analysis function. Then the solution of the equation is converged for calculation of the unknown number. In such a constitution, the analysis and the handling can be simplified even in a system where the members larger than the secondary value of the unknown number emerging in a Lagrange's equation like the motion, inharmonious vibrator and relativistic motion equations, etc., of a multi-particle system having an interaction of a complicated double body potential.

The support member 22 is positioned while the machine screws 25a to 25c are kept loosened, and then the machine screws 25a to 25c are tightened.  When the positioned support member 22 is fixed, only a force in parallel with the optical axis is applied to the support member 22 because the rotation control members 23a and 23b are provided between the heads of the machine screws 25a to 25d and the support member 22. Therefore, the position detecting device 21 is fixed being prevented from getting out of position.

Abstract: PURPOSE:To decrease the number of pinholes on the surface of a substrate and improve the surface-smoothness of the substrate by modifying the surface of a substrate with a thin film of silica or silica alumina formed by sol-gel method. CONSTITUTION:A surface of a substrate is coated with or a substrate is dipped in a metal alkoxide solution having a viscosity adjusted to several cPs by sol-gel method. The solution is hydrolyzed in air and converted into a vitreous or crystallized material by heat-treatment to form a thin film of silica (SiO2) or silica alumina (SiO2.Al2O3) on the substrate surface. The heat-treatment is carried out at a relatively low temperature (e.g. 400 deg.C) for about 30min. The thickness of the glass thin film formed on the substrate surface is >=0.3mum and the film has uniform thickness and smooth surface. When the film thickness is less than 0.3mum, the effect of coating treatment becomes insufficient and the smoothness may be deteriorated.

Title: Radiation detector
Inventor: FUTAHASHI TOKUAKI
IPC: G01T1/20
Filed: 1991-03-05
Abstract: PURPOSE:To improve the S/N ratio and spatial resolution in a radiation detector using a scintillator. CONSTITUTION:A radiation detector comprises a colimeter unit having colimeters for a plurality of channels, a scintillator unit having scintillators 25 for the plurality of channels corresponding to the colimeters 15 for respective channels, and a light convergence means, e.g. a microlens 11, formed in the protection glass 40 arranged at the output end of each scintillator 25. Radiation beam 31 coming into a colimeter 15 for a certain channel is colimated to go into a corresponding scintillator 25 and converted to a light beam 33. This converted light beam 33 is converged by the microlens 11 and is led to the photo-electric surface 7 of a photo-electric converter such as a photomultiplier and impinges on a predetermined position corresponding to the channel. Since the light beam 35 coming into the photo-electric surface 7 is fully converged, generation of optical crosstalk between channels is prevented and thus space resolution and S/N ratio are improved.

Title: Power supply device
Inventor: KIZU YOSHIHIKO
IPC: G05F1/56
Filed: 1985-03-27
Abstract: PURPOSE:To obtain a stable power supply which can change the set level of the output voltage with use of a hybrid type differential amplifier of the normal specifications, by using the 2nd comparator to perform the control so that the indication of a setting means is neglected when the output voltage is lower than a prescribed level. CONSTITUTION:The output voltage V0 is monitored by the 2nd comparator 6, and the setting output of a setting part 42 is neglected by a logic gate 52 when the voltage V0 is lower than a prescribed level VOL. Meanwhile a current ISINK serving as the analog output of an operating part 32 is kept at '0'. This prevents a case where the potential of an error comparator 2 is set at a negative level when a power supply is applied and before the level of the output voltage is raised up. While a mask is removed when the voltage V0 exceeds the level VOL and the part 32 flows the current ISINK according to an indication of the part 42. Thus a voltage control part is controlled at a balanced point of the comparator 2. Then the voltage V0 is stabilized at its set level.

Title: Battery pack
Inventor: HAMAZAKI RYOICHI
IPC: H01M10/60
Filed: 1999-03-10
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive simple structure and improve durability against vibration, or dropping, and safety by covering the outer circumference with silicone rubber and specifying a heat conductivity of the silicone rubber. SOLUTION: The outer circumference of this battery pack is covered with silicone rubber 3 with a heat conductivity of 2.9×10-3-7×10-3 cal/(cm.sec. deg.C). In this way, in spite of increase of a battery temperature due to a short circuit in a battery, heat of the battery is dispersed via the silicone rubber, so that a temperature rise can be suppressed, and consequently, safety can be improved. In addition, when a battery insertion port of the silicone rubber 3 is narrowed by 1.5% of the battery diameter for a cylindrical battery, for example, tight adhesion with the battery outer circumference can be accomplished easily, so that the heat conductivity can be improved further.  If Shore hardness(Hs) of 70-90 is provided for the silicone rubber 3, exterior strength can be secured, and consequently, protection, shape stability, vibration resistance, and impact resistance of the battery can be improved.
