Title: Optical microscope
Inventor: KAWADA SATOSHI
IPC: G02B21/06
Filed: 1990-09-18
Abstract: PURPOSE:To realize manifold illumination and easy space coherence control by employing such constitution that the light source of the illumination system of an optical microscope is formed in a LED array, and the shape itself of the light source can be changed by light control. CONSTITUTION:The light source of the illumination system is comprised of high luminance light emitting diodes 2 on each of which the light control can be applied independently, and it is arranged on the front side focal point plane of a condenser lens 4. The illumination strength can be controlled by the number of light of light emitting diodes 1, and also, the shape of the light source itself is changed by selecting the pattern of the light emitting diode to be lit, thereby, zonal illumination, oblique illumination, and dark field illumination can be performed. In such a way, the miniaturization and light weight of a chemical microscope can be attained, and also, the manifold illumination i.e. a various kinds of space coherence control can be easily and quickly performed.

Title: Recording method
Inventor: DAITO CHIAKI
IPC: B41M5/28
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To realize a writing property, which is nearly the same as that of plain paper, prevent from curling and make a high speed and high resolution recording possible by a method wherein colors are developed in a coloring agent of a recording paper by applying heat energy without contacting with the one layered recording paper, which is prepared by adding a coloring agent to a base paper component. SOLUTION: When a pulsed light is applied from a semiconductor laser 6, to which light is condensed by a condensing lens 7, to a recording material 1, the temp rature of an irradiated portion of a pulp fiber 2-containing recording material 1 rises quickly. Due to this temperature rise, an electron donable component 4 and an electron acceptable component 5 are melted and reacted with each other, resulting in developing color. After that, when the irradiation of the semiconductor laser 6 is gone, the material quickly cools down. However the developed color is retained. By prolonging the irradiation time of the irradiating semiconductor laser 6 at this time, a region, which is heated and reaches a coloring temperature, is widen, resulting in allowing to control the magnitude of a recording spot.  Further, by enlarging the absorption coefficient to the coloring wave length of the semiconductor laser 6 of the recording material 1, an energy is efficiently absorbed and an efficient color development results.

Title: Production of copolyether polyol
Inventor: IMAMURA KAZUYOSHI
IPC: C08G65/28
Filed: 1996-09-20
Abstract: PROBLEM TO BE SOLVED: To produce a copolyether polyol while preventing the compositional ratio from fluctuating by distilling the water formed as a result of reaction out of the reaction system by vaporizing it together with tetrahydrofuran, removing the water from the distillate and returning the tetrahydrofuran to the reaction system. SOLUTION: Tetrahydrofuran (hereinbelow referred to as THF) and a 2-10C diol (e.g. neopentyl glycol) are fed into a reactor fitted with an agitator, a distillation device and a condenser, and a specified amount of a heteropoly acid catalyst (e.g. phosphotungstic acid) is added to the mixture. The entire mixture is heated to 30-90 deg.C and agitated for about 15hr, and the water formed in an amount larger than that used in the reaction is distilled out of the reaction system together with THF. The distillate is sent to the bottom of a molecular-sieve-packed adsorption tower to adsorptively remove the water from the distillate. The distillate devoid of the water is withdrawn from the top of the tower and wholly returned to the reactor. After the reaction, the reaction solution is left in a quiescent state at room temperature to separate it into two layers. The upper layer is withdrawn, and Ca(OH)2 is added thereto to precipitate the contained catalyst, which is removed by filtration. The THF is removed from the filtrate by distillation to leave a transparent copolyether polyol.
