Title: Precoat type filter
Inventor: INAMI ICHIRO
IPC: B01D37/02
Filed: 1988-02-05
Abstract: PURPOSE:To increase clad removal rate and make the backwashing cycle longer by precoating an element with an oxidized filter aid composed of ion exchange resin powder and constituting of a precoat type filter. CONSTITUTION:Oxidized ion exchange resin powder is prepared by oxidizing powdery ion exchange resin or pulverizing oxidized ion exchange resin. As element is precoated with a filter aid composed of said oxidized ion exchange resin powder to form a precoat type filter. As clad collection in the precoated layer by said filter is not only by means of a simple interruption filtration but also of occlusion in the resin particles by adsorption, dissolution and diffusion, and even ultrafine particles can be collected. As the collected clads are occluded in particles, clogging is relaxed and the degree of increasing pressure difference gets smaller.

Title: Detector for breaking of wire
Inventor: TANOGAMI ETSURO
IPC: G01R31/02
Filed: 1987-02-04
Abstract: PURPOSE:To securely detect an electricity feeder where the breaking of a wire occurs by detecting a voltage applied to the electricity feeder and a current flowing through the electricity feeder or its temperature. CONSTITUTION:When an electric contact 3a is closed while a green lamp 1a among 1a-1n has a wire break, the output of an AND circuit 12a is '0'. At this time, an electric contact 4a of a red lamp is opened, therefore, the output of a NAND gate 15a is also '0'. Consequently, the output of an OR circuit 14a varies from '1' to '0' and the output of a NAND circuit 15a is inverted from '0' to '1'. Consequently, an FF 16a is set and a wire breaking display device 17a illuminates. Therefore, it is confirmed that the breaking of a wire occurs to either of the green lamps 1a and red lamp 2a. Further, a temperature sensor which detects the heat generation of a pilot lamp is usable instead of a current detector.

Title: Semiconductor device
Inventor: NASHIMOTO YASUNOBU
IPC: H01L29/778
Filed: 1990-02-01
Abstract: PURPOSE:To reduce a series resistance between a source electrode and a gate electrode by setting secondary electron gas concentration except a part directly under the gate electrode to a maximum amount to be determined according to a difference of electron affinities between two types of semiconductors for forming a hetero junction and an impurity concentration in an electron supply layer. CONSTITUTION:A first undoped semiconductor layer 2 is epitaxially grown on a semi-insulating compound semiconductor substrate 1, a second N-type semiconductor layer 3 having smaller electron affinity than that of the layer 2 is epitaxially grown through a hetero junction, and source, drain electrodes 6, 7 ohmically contacted through a control gate electrode 12 formed thereon are provided. In this case, the electron concentration of secondary electron gas 5 generated in the layer 2 along a hetero junction boundary except a part directly under the electrode 12 is always set to a maximum concentration to be determined according to a difference of electron affinities of the layers 2, 3 and an N-type impurity concentration in the layer 3. Thus, a series resistance between the source electrode and the gate electrode can be largely reduced to improve the performance of a field effect transistor.

Title: Silver/silver halide reference electrode, its formation and ion-selective electrode
Inventor: TERAJIMA MASAAKI
IPC: G01N27/30
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To avoid mixture of heavy metal elements into a silver halide layer and correctly determine the activity of specific ions in a sample by using an oxidizing agent which does not influence silver halide generated. SOLUTION: A silver halide layer is formed by oxidizing a surface of a silver layer with a peroxide in the presence of a halide. At this time, if the used peroxide is, for example, hydrogen peroxide, the silver layer can be uniformly oxidized because the hydrogen peroxide foams severely during the reaction. Moreover, heavy metal elements originated from the oxidizing agent are prevented from being included in the silver halide because the hydrogen peroxide is dissolved to oxygen and water. The ion-selective electrode with an ion selectivity applied to the silver/halide silver reference electrode shows superior electrical responsivity.

The state of the intersected point A is the steady state of the furnace, and if the length of the arcs is increased to the point B together with the electric power to be supplied when, for example, the temp. of the slag 7 decreases, the temp. of the steel 6 is made invariable. Thus, the temps. of the steel 6 and the slag 7 are maintained adequately by controlling the electric power to be supplied and the length of the arcs in the above-mentioned way.

Abstract: PURPOSE:To remarkably improve unpleasant feeling on a user and a troublesome operation by rewinding a recording medium automatically to the forefront of a recording block where recording is interrupted when the recording medium at a dubbing side arrives at termination before the recording of a recording content is completed. CONSTITUTION:A master deck 1 converts a digital signal recorded on the recording medium to a voice signal. A display device 4 displays desired information at that time. A dubbing deck 2 is provided with a CPU, and when a cassette tape arrives at the termination in performing dubbing, the CPU judges that the interruption of music is generated if a signal existance state is shown by a no signal part detecting means, and issues a command to rewind the tape to a deck mechanism, and also, displays the interruption on the display unit 14, and stores the identification information of the music. Rewinding is stopped when a no signal part, that is, the program searching part of the music is detected. Therefore, it is possible to recognize the music in which the interruption is generated and the forefront part of the music and to respond to that immediately.
