Title: Manufacture of graphite powder for lithium ion secondary battery negative electrode
Inventor: JO TAKESHI
IPC: H01M4/587
Filed: 1999-07-05
Abstract: PROBLEM TO BE SOLVED: To enhance discharge capacity and charge/discharge efficiency by crushing a bulk mesophase having a specific amount of a volatile portion and then carbonizing and graphitizing it with no substantial crushing. SOLUTION: A graphite powder is obtained by carbonizing and graphitizing a bulk mesophase having volatile matter of 1-15 wt.% The bulk mesophase is produced as follows: Tar and/or pitch are used as a starting material and are heated in the presence of a nitrating agent to be polymerized. A nitric acid or the like is used for the nitrating agent and the added amount thereof is preferably 0.1-15 wt.% of the starting material. Additionally, a heating temperature is preferably set at 300 deg.C or above but less than 400 deg.C. The polymerized raw material is heated to be mesophased. A heat treatment is preferably conducted at temperatures of 400-600 deg.C. The generated mesophase is crushed before the carbonization and is not substantially crushed after the carbonization. Therefore, the mesophase is crushed to have desired grain size for the graphite powder at this stage.

Title: Noise suppression device for television signal
Inventor: SUENAGA SHINICHI
IPC: H04N5/21
Filed: 1989-07-24
Abstract: PURPOSE:To reduce quantization noise and random noise by improving the resolution of input and output television signals and revising an output level of an arithmetic means depending on the amplitude of the input television signal. CONSTITUTION:The resolution of an input television signal A inputted from an input terminal 1 is increased to 8-bit from a conventional 6-bit.

Title: Binder for injection-molding ceramic and method for removing binder
Inventor: FURUKAWA HIROFUMI
IPC: C04B35/64
Filed: 1988-08-02
Abstract: PURPOSE:To prevent generation of deformation and a crack of a molded ceramic body and to shorten time for removing a binder by utilizing urea resin incorporating the specified amount of a water-insoluble thermoplastic compd. as the binder. CONSTITUTION:This binder for injection-molding ceramic incorporates 5-20-vol.% water-insoluble thermoplastic compd. and consists of the balance urea resin. For example, as the water-insoluble thermoplastic binder, the substance obtained by mixing wax of a low molecular compd. or acrylic resin of a high molecular compd. with urea resin is utilized. Urea resin incorporated in the binder as a main component is dissolved out and removed by immersing the molded ceramic body which has been injection-molded while utilizing this mixture as the binder in water or by treating the molded ceramic body with steam in an autoclave. Thereby gasification and expansion of the binder are not caused and therefore a crack and deformation are not generated for the molded body. Further time for removing the binder can be drastically shortened.

When alphabetic characters or numerical characters will be inputted on the way of input of this character string, a mode switching key 1c is continuously depressed to input alphabetic characters or numerical characters as half size characters. When KANA characters or KANJI will be inputted after input of alphabetic characters or numerical characters, the mode switching key 1c is released to stop the operation, and KANA characters and KANJI are inputted as full size characters. Thus, the character string where half size chracters and full size characters are mixed is inputted with the easy operation.

Abstract: PURPOSE:To decrease crosstalks and to improve an extinction ratio by forming a thin film having the refractive index higher than the refractive index of optical waveguides and a thin film having the refractive index lower than the refractive index of the optical waveguides between an input side end face and electrodes. CONSTITUTION:A buffer layer 3 consisting of SiO2 is formed at 3000Angstrom  on the surface of a waveguide substrate 1 in order to decrease the absorption loss of TM mode light on the electrodes and to make low voltage operation and the electrodes 4 consisting of CrAu are formed atop this layer. The Si thin film 6 (900Angstrom ) having the refractive index higher than the refractive index of the optical waveguides 2 and the SiO2 thin film 5 (2000Angstrom ) having the refractive index lower than the refractive index of the optical wave guides 2 are formed over the entire surface of the region (about 5mm length) on the surface of the substrate 1 between the substrate 1 and the part formed of the input side end face fixed with a constant polarization optical fiber 7 and the electrodes 4. The above-mentioned film thicknesses sufficiently attenuate only the TE mode and do not attenuate the TM mode. The crosstalks are decreased in this way and the extinction ratio is increased.
