Title: Battery charging method
Inventor: BROTTO DANIELE C
IPC: H01M10/44
Filed: 1999-06-11
Abstract: PROBLEM TO BE SOLVED: To avoid generation of a battery which is charged insufficiently by invalidating the end of charging method based on temperature when a temperature changing rate has exceeded the first threshold value within the predetermined period and the validating again when the temperature changing rate becomes smaller than the second threshold value. SOLUTION: A controller calculates a temperature changing coefficient (dT/dt). When dT/dt is smaller than the threshold value X, it is determined whether a counter value is higher than or equal to the threshold value A. When the counter value is higher than the threshold value A, battery charging is continued (ST5 to ST9). When dT/dt is larger than the threshold value X, end of charging process based on the temperature is invalidated. Next, battery temperature is detected and dT/dt is calculated to determine the comparison result of comparison with threshold value Y (ST11 to ST14). The controller repeats these steps until the predetermined time has passed while the dT/dt becomes smaller than the threshold value Y. When any condition is matched, end of the charging process based on the temperature is validated again.

Title: Data conversion system using three-dimensional isoparametric smoothing method
Inventor: HARADA MASANORI
IPC: G06F17/50
Filed: 1989-06-27
Abstract: PURPOSE:To improve the calculation accuracy of a finite element method by distributing the position data on the nodal points of elements of a hexahedron so as to secure the equal distances among the nodal points in each direction of the orthogonal coordinates and then moving the nodal points to secure a clean alignment of those element. CONSTITUTION:The position data on the nodal points of elements of a hxahedron obtained by a 3-dimensional solid mesh generator are distributed so that the equal distances are secured among the nodal points in each direction of the orthogonal coordinates X - Z via a single direction equal distributor. Then those nodal points are moved by a 3-dimensional isoparametric smoothing method so that each element has a clean form. That is, the nodal points are equally distributed in the direction Z when the grids are produced in the three directions. Under such conditions, a point (0, 0, 0 ) are set at the end of the direction Z and therefore not moved. Then a point (0, 0, 1) is moved to the middle point between adjacent points (0, 0, 0) and (0, 0, 2) in the direction Z. As a result, the elements approximate to a right hexahedron and the calculation accuracy is improved with a finite element method.

Abstract: PURPOSE:To facilitate the manufacture of planar type n-p-n transistor withstanding voltage in the reverse direction exceeding 700V by a method wherein Ga is thinly diffused from P layer side of N type semiconductor substrate to compensate and eliminate the inversion layer. CONSTITUTION:The expansion of depletion layer at p-n junction disturbing high voltage withstanding activity of planar type transistor is under the influence of depletion layer of Si substrate surface mainly caused by diffusion mask or Na<+>, K<+> ion in the surface protecting thermal oxide film. For example, N<+> layer is formed by means of P diffusion from back side of N type Si substrate and selective diffusion of B and P from surface successively utilizing the thermal oxide film as a mask to form p type based and n type emitter. Then Ga is diffused over the surface up to the area of 5X10<15>-1X10<17> and the thickness of 0.1- 1.7mu before providing electrode. Through these procedures for diffusing Ga, the planar type semiconductor device with high withstand voltage conventionally hard to be available may be manufactured easily.

Abstract: PURPOSE: To detect whether the container of a copying machine, etc., contains conductive powder or not, by making use of variation in the impedance of a high- frequency oscillation coil by an adjacent conductive body.  
     CONSTITUTION: On an external wall close to the bottom of side plate 4 of hopper 1 of a copying machine, detection coil 5 constituting one part of a high-frequency oscillation circuit is installed. The output of this oscillation circuit is led to a circuit composed of a rectifier circuit, switching circuit and display lamp.

Detecting this makes it possible to display whether there is powder left in hopper 1 or not. Further, the detection coil is fitted to any other transport pipe than the hopper to detect the existence of the powder in the transport pipe. In this way, the existence of the conductive powder in the container which can not be confirmed by the eye can easily be detected.
