Title: Pointing device and output data processing method
Inventor: OKUMURA FUJIO
IPC: G06F3/0354
Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To provide a pointing device which can be miniaturized and also can be used as a pen type mouse by using a two-dimensional photosensor having a window, a light source and a fiber array plate. SOLUTION: A position detector 10 consists of a two-dimensional photosensor 30 having a window which includes plural photodetector elements having the light transmitting windows formed on their backs and the electronic switches arranged in a matrix form, a light source 1 which is placed at the back side of the photosensor 30 and a fiber array plate FAP which is placed at the surface side of the photosensor 30 and includes a bundle of short optical fibers 9 having the diameters larger than those light transmitting windows. As no lens is used at the sensor part which reads a pattern, the distance between the photosensor 30 having a window and a pad 20 having a pattern can be reduced down to about 1-2 mm. Furthermore, the distance can be set at only 1 mm or so between the light source 1 and the photosensor 30 since the source 1 can be placed adjacent to the photosensor 30.

Abstract: PURPOSE: To obtain the subject compound having a high purity, by separating from a mixture of ethylphenol isomers by utilizing a simple means of using a specific host compound capable of selectively forming a host guest complex with m-ethylphenol. CONSTITUTION: This method for the separation and purification of m-ethylphenol comprises contacting a mixture of ethylphenol isomers containing m-ethylphenol with a host compound consisting of tetraphenylphosphonium bromide or 1,1-di(4- hydroxyphenyl)-cyclohexane to precipitate a material containing a host guest complex of m-ethylphenol, and then separating a solid from a liquid. Preferably, by adding 0.2-2 fold mol host compound to the above isomer mixture, heating up to 100-150 deg.C to provide a uniform phase and then cooling to (-)5-15 deg.C, the complex crystals are precipitated. Further, in order to obtain the object compound from the above complex, the complex is preferably heated at 150-200 deg.C under a reduced pressure sufficient for vaporizing m-ethylphenol at that temperature to decompose and vaporize the complex.

Title: Method for setting waiting time after pouring molten metal in molten metal feeding equipment
Inventor: KAWAKURA TSUKASA
IPC: B22D17/30
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To provide molten metal in a die cast machine at the optimum timing while the temperature drop of the molten metal in a ladle is controlled to a minimum. SOLUTION: A ladle 14 of a molten metal feeding device 3 feeds the molten metal in a melting furnace 1 to a pouring sleeve 23 of a die cast machine 2 while reciprocating between the molten metal ladling position P1 and the molten metal pouring position P2 . The waiting time after pouring the molten metal until the ladle after finishing the pouring at the molten metal pouring position P2 starts the retraction toward the molten metal ladling position P1 , is calculated by making a correction with the difference between the mean cycle time of N shot of the die cast machine 2 and the ideal cycle time with the waiting time before the pouring of the ladle 14 at the molten metal pouring position P2 is minimized as a reference. Even when the cycle time of the die cast machine 2 is fluctuated, the waiting time before pouring the molten metal at the molten metal pouring position P2 is prevented from being increased, and the temperature drop of the molten metal in the ladle 14 can be avoided.

Abstract: PURPOSE:To make a bright, high-performance lens system possible with a small number of lenses by causing a first lens, which is a radial heterogeneous lens having positive refractive power, to meet specific conditions. CONSTITUTION:A first lens which is a radial heterogeneous lens having positive refractive power, a second lens having negative refractive power, and a third lens having positive refractive power are disposed in sequence from the side of an object.

By meeting the conditions represented by the expressions I-IV the radial heterogeneous lens is concave and the medium has positive refractive power and the whole lens system also has positive refractive power. The expression III indicates the condition for correcting chromatic aberration well. The system therefore has high refractive index and works as glass of low dispersion.
