Title: Surface-modification of sic whisker
Inventor: SUGIHARA TAKAOMI
IPC: C30B29/62
Filed: 1990-08-02
Abstract: PURPOSE:To obtain an SiC whisker useful as a composite reinforcing material for ceramic and effective in improving the breaking toughness of the composite material by using a polysilazane as a reaction substrate and forming an Si3N4 coating film on the surface of SiC whisker. CONSTITUTION:A polysilazane is dissolved in an organic solvent, SiC whisker is dispersed in the solution and the obtained dispersion is filtered, dried and baked in a nitriding atmosphere at 1100-1600 deg.C to form an Si3N4 coating film on the surface of the SiC whisker. The concentration of the SiC whisker dispersed in the organic medium is preferably 50-200g/l. Since polysilazane is highly hydrolyzable, the drying after the filtration is preferably carried out under condition avoiding moisture as far as possible.

Abstract: PURPOSE: To provide the logic circuit to be surely operated even at the time of different signal voltages by connecting first and second resistors respectively between the emitter and base of a switching transistor(TR), of which the emitter is connected to a power source, and to the base. CONSTITUTION: For example, respective mute terminals 1 and 2 generate the first and second different mute signals of 5V and 3.5V at the time of mute. Corresponding to the first mute signal, potential difference between the emitter and base of a (p) type switching TR Tr1 , which is connected with the power source of 5V and connects resistors Rl and R2 of required resistance values respectively between the emitter and the base and to the base, is turned to 0V, the TR Tr1 , is turned off, nTR Tr3 and Tr4 are turned on, and a voice input is muted not to be outputted. Corresponding to the mute signal of 3.5V from the mute terminal 2, the potential difference between the emitter and base of the TR Tr1 is not turned to 0V but turned to a voltage lower than the threshold value of TR Tr1 through the resistors R1 and R2, and the TR Tr1 is not turned on.  Thus, the mute logic circuit can be provided to be surely operated even when the different signal voltages are used together.

Title: Photoelectric converter
Inventor: SHIMANAKA MASAYA
IPC: H04N1/401
Filed: 1993-07-29
Abstract: PURPOSE:To detect the quantity of dispersion in picture elements precisely matching a wavelength at a high spectral sensitivity with a wavelength at a high reflecting characteristic of a reference object color. CONSTITUTION:A white light 1a emitted from a light source 1 is reflected in a reference object 2. Since a high spectral ratio reflectance of a color of the reference object 2 corresponds to a high spectral sensitivity of a photoelectric conversion element, a reflected light 1b has a wavelength in matching with that of a high spectral sensitivity of the photoelectric conversion element 3. Since a level of an electric signal from the element 3 receiving the light 1b is sufficiently high, the effect of noise is very less. The reflected light 1b with respect to the light 1a is received by the element 3 and converted into an electric signal 10c, and a correction means 9 corrects the signal 10c based on a reference level 2d of a storage means 8 to obtain a picture signal 10c. Since the level of the electric signal 2c of the element 3 is sufficiently high, the reference level 2d receives less noise effect. Thus, the reference level 2d used to detect the quantity of the dispersion in picture elements accurately is obtained.

Title: Compound structure o-ring
Inventor: KOBAYASHI OSAMU
IPC: F16J15/10
Filed: 1996-07-18
Abstract: PROBLEM TO BE SOLVED: To seal a vacuum state and corrosive fluid effectively by making a rubber core material to a supercritical fluid extraction processing part, in the O-ring with a compound structure formed by installing a coating layer on the surface of an O-ring shape rubber core material. SOLUTION: A coating layer is installed on the surface of O-ring shape rubber core material, in the O-ring with a compound structure. The O-ring shape rubber core material formed in a solid shape or hollow shape by s compression molding method is processed by a supercritical fluid extraction(SFE). The SFE processing is carried out by using an arbitrary fluid which can form a supercritical state at a temperature, by which a rubber shape substance is not deteriorated, or less. In a pressure condition, the supercritical state is different by the kind of an used fluid and a processing time is also different by an extraction liquid, flow rate and the kinds of core material. After this SFE processing, an usual temperature and usual pressure state are returned by the decompression speed of about 10-200kgf/cm<2> /hr and the temperature reduction speed of about 5-72 deg.C/hr.  Thus, the coating layer is formed on the surface of O-ring shape rubber core material SFE processed.
