Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To heat sample reaction cases subjected to dispensation sequentially and continuously and then retain the heat of cases by providing a heating bath and a heat retaining bath independently. SOLUTION: A plurality of sample reaction cases M to be exchanged are previously retained at a target temperature in a temperature retaining bath 20. Cases M subjected to dispensation of reaction substance are fed to a heating bath 10 at a constant interval and heated sequentially and individually up to a target temperature. The heated case M is transferred, by a transfer means 30, from the heating bath 10 into the temperature retaining bath 20 and an arbitrary case M to be exchanged is discharge from the inside of temperature retaining bath 20 to the outside. Subsequently, each case M is deposited with reaction products in the temperature retaining bath and retained at a predetermined target temperature for a predetermined time after being transferred into the temperature retaining bath.  At the same time, new cases M subjected to dispensation are heated one by one in the heating bath 10 and transferred sequentially into the temperature retaining bath 20.

Title: Method and apparatus for computation of texel value for display of texture on object
Inventor: UORUTAA II DONOBUAN
IPC: G06T15/04
Filed: 1995-12-19
Abstract: PROBLEM TO BE SOLVED: To generate a texel value with the least number of section points while maintaining a texel accuracy decision criterion by selecting section points which draw respective scanning line segments most suitably along each scanning line and making the intervals of the section points as wide as possible. SOLUTION: The section points which draw the scanning line segments are adaptively selected along each scanning line and the intervals of the section points are made as wide as possible without exceeding a selected texel accuracy criterion. End points of scanning lines are adjusted to integer pixel coordinate positions by an adaptable method for truncation, discarding, or raising. When the spans are sufficiently long and the benefits of fractionation are gained very much, the spans of the scanning are fractionized into the least number of small sections at optimum intervals most suitably. After a section point is selected, accurate texel values at two integer end points are calculated first. Lastly, an approximate texel value of an intermediate pixel positioned between an adjacent end point of each scanning line and the section point is generated.

Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To preferably control the exothermic reaction and to easily assemble into a large-size device by using the reaction heat generated in the reaction to heat the starting gas to the required reaction temp. by indirect heat exchange based on the countercurrent principle. SOLUTION: As for the reactor, a reversal countercurrent reactor consisting of two concentric tubes comprising a tightly sintered aluminum oxide ceramic material is used. The inner tube 1 is equipped with a catalyst bed 3 at the upper end part, while the outer tube 2 is closed at the top end, namely, the top of the reactor. When the starting gas mixture is introduced from the lower side to the inner tube 1, the mixture passes through the catalyst bed 3 and turns downward in the ringlike space between the inner tube 1 and the outer tube 2. At the initiation of the reaction, it is necessary to heat the starting gas mixture and the catalyst to >=800 deg.C. This heating process is carried out by direct heating of the catalyst by a heater jacket or a current surrounding the outer tube 2.  After the reaction is initiated, it is enough to use the generated reaction heat to heat the starting gas mixture to the reaction temp.
