Abstract: PROBLEM TO BE SOLVED: To obtain the subject composition, having a high silicon content, providing a coating film having a high hardness and high scuff and heat resistnaces and excellent in preservation stability by usually dispersion a gel consisting of a specified alkoxysilane compound in a solvent. SOLUTION: This composition is obtained by dispersing a gel obtained from an alkoxysilane compound of the formula (R<1> O)n -Si-R<2> 4-n [R<1> is a 1-4C alkyl; R<2> is an alkyl, an aryl, etc.; (n) is 3 or 4] (preferably tetramethoxysilane prepared by reacting silicon with methanol). A method for adding, e.g. water to the alkoxysilane compound and carrying out the hydrolyzing and condensing reaction is cited as the method for preparing the gel. In this case, water in a >=1 equivalent amount for the alkoxy groups in the alkoxysilane compound is preferably used. The gel dispersion is usually performed in a solvent. A pigment, a powder and an additive for improving coating film properties may further be added and dispersed in the objective composition.

Title: Transmission control system
Inventor: ISHIBASHI YUTAKA
IPC: H04L5/16
Filed: 1987-08-10
Abstract: PURPOSE:To reduce a processing quantity required for the inversion of transmission right by awaiting a succeeding transmission data for a time even when no transmission data exists in a transmission data buffer and sending the data after the transmission data arrives thereby reducing the number of times of transmission right inversion. CONSTITUTION:If a transmission data is lost from the transmission data buffer 2 before a consecutive transmission data counter 4 reaches a predetermined value, the operation of a transmission right timer 5 is started and the arrival of the transmission data is awaited from the transmission data generating source 6 to the transmission data buffer 2. When the transmission data arrives in time, the transmission control circuit 1 sends the transmission data 7 to a transmission medium 3 to stop the operation of a transmission right timer 5. If hot arrived, the transmission right is transferred. Thus, the number of data awainting the acquisition of the next transmission right as the result of arrival after the transfer of the transmission right is reduced and the number of times of inversion of the transmission right is decreased.

Title: Language analyzing device
Inventor: KOYAMA NORIKO
IPC: G06F17/28
Filed: 1987-08-11
Abstract: PURPOSE:To reduce storing capacity, to ease dictionary retrieval and to shorten a necessary time for the retrieval by sharing the contents of a dictionary for converting language notation and a knowledge dictionary for analyzing the language. CONSTITUTION:The titled device is constructed with sharing index data 6 by a notation converting dictionary part 4 used in a notation converting part and an analysis dictionary part 5 used in an analyzing part. Accordingly, the index data, which are registered in one dictionary part, can be used in the other dictionary part and the dislocation of a dictionary is erased. Further, since the index data are mutually shared, the memory capacity goes to be reduced for constructing the dictionary. The dictionary index data, which are used for the notation converting processing, can be also used for the language analyzing processing as they are. Thus, the storing capacity can be reduced, the dictionary retrieval can be eased and the necessary time for the retrieval can be shortened.

Title: Photographing device
Inventor: ITOU YUUJI
IPC: G02B7/04
Filed: 1981-12-11
Abstract: PURPOSE:To decrease unnecessary length of optical path and to reduce the size of a titled device by disposing a pair of optical elements for focusing of which the combined refracting power changes when the elements are relatively displaced within the plane perpendicular to the optical axis in the optical path of a photographing system. CONSTITUTION:When the eyegrounds Ef is illuminated by putting an observing light source 22 on, the primary fundus image Ef' is formed by an objective lens 1. The luminous flux from the image Ef' passes through a stop 2 and is made into parallel light by a positive lens 3. The parallel light is made incident to a variable refracting power lens 4, by which the magnification is changed; thereafter, the light is made incident to a stationary lens 5. Since a photographinc lens Z is set at a focal length, the image is formed as the secondary image Ef'' of a desired magnfication on a film 10. If the lens elements 4a and 4b are changed in mutually opposite directions by operating a moving mechanism with the sharpness of the fundus image as a measure, the combined magnification of the lens 4 changes; therefore, the image Ef' and the film 10 are made conjugate. Thus, the size of the device is reduced by moving the lens 4 in proximity to the stop 2.

Title: Constant voltage circuit
Inventor: NITTA SHOZO
IPC: G05F3/30
Filed: 1989-08-03
Abstract: PURPOSE:To make output voltage vary in following perfectly the variation of supply potential so that the potential difference of the output voltage from the supply potential is kept always constant by making the fundamental configuration of this constant voltage circuit of a band gap circuit, and adding a feedback loop to it. CONSTITUTION:As for the operation of the constant voltage circuit, because the feedback loop 10 is added to this circuit, when negative supply potential VEE falls, for instance, the on-current of a transistor (TR) Q5 increases, and since it permits larger quantity of a current to flow through a resistor R4, the base potential of the TR Q1, as a result, the emitter potential falls, and the output voltage Vref falls. On the contrary, when the negative supply potential VEE rises, the on-current of the TR Q5 decreases, and since it permits smaller quantity of the current to flow through the resistor R4, and base potential of the TR Q1, as a result, the emitter potential of it rises, and the output voltage Vref rises. Thus, the output voltage Vref comes to vary in following perfectly the variation of the negative supply potential VEE, and the potential difference of the output voltage Vref from the negative supply potential VEE becomes alway constant.
