Title: Electrode for fuel cell
Inventor: TANAKA TOMOJI
IPC: C25B11/03
Filed: 1990-11-19
Abstract: PURPOSE:To generate electricity or electrolyze effectively as a fuel cell instead of a platinum electrode by forming an electrode as a porous compact by casting silicon manganese, silicon iron and/or the like in a casting mold or by sintering/ processing these metals as granulated powder. CONSTITUTION:By casting silicon manganese, silicon iron, silicon nickel, silicon silver or silicon selenium in a casting mold, or by sintering after making these metals into granulated powder, an electrode for a fuel cell is formed. Here, an electrocast brick 4 is embedded in a metallic tube 3 by ascending/descending high pressure press boards 1 and 2 vertically, and metallic powder of a packing is spread all over the space between the tube 3 and the brick 4 so that cushioning nature can be given. Furthermore, cavity body type copper electrodes 6 and 7 are inserted into both edges of the brick 4, and they are cooled by circulating cooling water in the cavities. They are processed by means of compression while ascending/descending the press board 1 vertically, and voltage is impressed upon the copper electrodes, and a sintered body is heated as an electric resistance by means of red heat. Thereby, the granulated powder is sintered so that a porous electrode 10a and the like can be formed.

Title: Plastic cap
Inventor: DOI KOICHI
IPC: B65D41/32
Filed: 1988-12-14
Abstract: PURPOSE:To make it easy to fix the engagement a plastic cap to the chin part of a container at the time of capping and prevent a band from breaking by making the shape of the flat cross section of a pilfer proof band an approximately polygonal shape. CONSTITUTION:A pilfer proof band 2 is provided at the lower end of a skirt shaped side wall 4 through a perforation type weakened line 5. The perforation type weakened line 5 is composed of perforated windows 5a and bridge parts 5b between them. The shape of the flat cross section of the pilfer proof band 2 is made a polygonal shape for which wide parts 10 and narrow parts 11 are alternately formed. On the inner wall side of the wide parts 10, a taper shaped thickened part 13 is formed. At the same time, above the wide part 10, only perforated windows 5a are formed, and the bridge part 5b is not placed at all. In the meantime, above the narrow part 11, at least at both side ends, bridge parts 5b are placed. By doing this, the thickened part 13 can easily go across a chin part A at the neck of a container. In addition, when the thickened part goes across the chin part A and engages with the chin part A, the engaging force becomes extremely strong.

Abstract: PURPOSE:To remove noises and to improve the S/N of a signal by using an analysis part which converts a signal containing noises into a feature vector and a neural network which outputs the index of a representative vector in a corresponding cluster when the feature vector is inputted. CONSTITUTION:The voice signal which contains noises is converted by the analysis part into an autocorrelation coefficient 02 and the maximum value 104 is detected as dummy power by a maximum value detection part 103 and normalized by a normalization part 105. The normalized autocorrelation coefficient 106 is inputted to the neural network 107 in hierarchic structure wherein the units of the input layer, intermediate layer, and output layer are weighted and coupled and the neural network 107 outputs the index 108 of the representative vector in the best corresponding cluster.

IPC: H04N5/235
Filed: 1989-11-30
Abstract: PURPOSE:To improve the resolution of a video image by compressing a white level, expanding a black level via a nu circuit at rear light, applying rear light correction while keeping the gradation of background and increasing the gain of a high frequency component of a video signal. CONSTITUTION:A high frequency signal subject to gamma correction at a gamma correction circuit 9, separated by an LPF 11 and an HPF 12 and extracted from the HPF 12 at rear light correction is subject to noise component elimination at a base noise clip circuit 13 and the resulting signal is inputted to a variable gain amplifier circuit 21. In this case, a control section generated by a rear light correction control signal generating circuit 10 is inputted via a control line 22 to the circuit 21 to control the signal so as to increase the gain for the high frequency component. Thus, the signal of an input waveform is subject to rear light correction at a nu circuit 8, an output signal whose white level is compressed and whose black level is expanded is obtained, however, since the high frequency component at the white level is kept high and no deterioration in the resolution of the video image is caused.

Filed: 1986-12-26
Abstract: PURPOSE:To perform stable selective epitaxial growth by using a mixed gas of SiC4 and H2 as the reaction gas, and performing a selective epitaxial growth of Si under a reduced pressure, thereby simplifying the control. CONSTITUTION:A substrate 1 is placed within a depressurized reaction chamber 11 and heated by a heater 12. As the reaction gas, a mixed gas of a SiCl4 and H2 which was bubbled by H2 is used. The SiCl4 gas is controlled by a flow meter 17 and the H2 gas is controlled by a flow meter 16. And the flow rate of each gas is controlled to a value suitable for a selective epitaxial growth, for instance, 500cc/min. for SiCl4 and 80l/min. for H2. Whereupon, one flow rate control of SiCl4 will be enough, while the prior method requires two flow rate controls of SiH2Cl2 and HCL. With this, the control is simplified and a stable selective epitaxial growth is performed.

Title: Bulletproof helmet
Inventor: NAGAI KANETOMO
IPC: F41H1/04
Filed: 1993-12-15
Abstract: PURPOSE:To enhance impact absorption against bullets or the like, and further reduce the weight of a bulletproof helmet and enhance its sitting features by placing expanded polystyrene having a specific foam magnifying power inside the helmet body as an impact absorption material against bullets or the like. CONSTITUTION:Expanded polystyrene is placed inside a helmet body 1 which is a bulletproof member and joined with a double face tape or an adhesive. The optimum expanded magnifying power is specified to be from 30 to 50 times, which makes it possible to provide excellent impact absorption. When the expansion magnification power is lower than 30 times, the impact absorption will be reduced accordingly, and it will be necessary to increase the thickness of the helmet body, which will result in the increase in the weight. It is difficult to manufacture helmet provided with foams of 50 times of expansion, and the impact absorption will be accordingly reduced, which is unfavorable to the helmets. It is advisable that the thickness of expanded polystyrene be set within the range from 15 to 30mm, which are usually adopted. This construction makes it possible to enhance elastic performance, and reduce the weight of the helmets.
