Title: Cut off of adhesion between base ship and sea bottom ground and device therefor
Inventor: YOSHINO YUICHI
IPC: B63C7/28
Filed: 1989-04-13
Abstract: PURPOSE:To surely cut off the adhesion between a ship bottom and the sea bottom ground in simple ways by shifting the whole of wires which are laid in crossing at right angles in the longitudinal direction of a hull along the ship bottom of a base ship, in one direction, shifting the both edges of the wire alternately. CONSTITUTION:When the adhesion between the ship bottom A of a base ship 1 and the soft sea bottom ground B is cut off, a plurality of winches 4 installed onto the base ship 1 are driven alternately, when the tide level rises to the draft position C of the base ship 1. A plurality of wires 5 are taken up alternately, and the both edges of a wire 6 for separation are shifted alternately. Therefore, a water channel D is formed, and the sea water E is introduced into the water channel D, and the sea bottom A and the sea bottom ground B are separated. At this time, if the degree of adhesion between the ship bottom A and the sea bottom ground B is strong, an air compressor 10 is operated to jet air F from a nozzle 9 on an air hose 8. Therefore, the jetted air F is used as exfoliating agent, and the adhesion between the ship bottom A and the sea bottom ground B can be easily cut off.

Title: Method and system for supplying informations to the deaf
Inventor: HARUTOMUUTO TORAUNMIYURAA
IPC: G10L25/48
Filed: 1976-08-04
Abstract: In a device for presenting information to deaf persons an electroacoustic signal from a microphone is supplied to a high-pass and to a low-pass channel via an amplifier. The relation between the envelope potentials of the high-passed and the low-passed signals is sensed by means of logarithmic circuits and a differential amplifier, the output potential of which determines the frequency of a voltage controlled oscillator. By means of a dynamic-adapting signal, derived from the electroacoustic signal, an amplitude modulation of the oscillator output is provided. The accordingly obtained amplitude modulated signal is used to drive tactile or auditive transducers.

IPC: H01M4/88
Filed: 1986-04-22
Abstract: PURPOSE:To ensure an electrolyte entering passage and a gas diffusion passage as previously arranged without a break by mixing hydrophilic carbon powder, water repellent carbon powder, and water repellent binder, and hot-pressing, then immediately cooling to form a reaction layer. CONSTITUTION:A mixture of hydrophilic carbon powder, water repellent carbon powder, and water repellent binder is sintered by a hot-press, then immediately cooled, or cooled with hot-pressed to form a reaction layer.

CONSTITUTION:A vehicle's load capacity is detected by a car level sensor 1, and on the basis of a car speed signal by a car speed sensor 4 and a throttle opening signal and a shift position signal of a throttle sensor 7, if a shift position is at low speed, the speed/acceleration of a vehicle is set to a positive direction but at high speed to a negative direction, respectively, and when the load capacity being detected by a loadage detecting sensor is light in weight, it is set to the positive direction but heavy in weight to the negative direction, respectively, and furthermore when a throttle of the throttle sensor is closed, it is set to the negative direction but opened, to the positive direction respectively. Thus it is inferred by a fuzzy inference inferring the grade of a road surface on which a vehicle is traveling as in a fact that when car speed in the car sensor is high speed, it is set to the negative direction but low speed, to the positive direction respectively, whereby the grade of the traveling road surface is detected in this way.

Abstract: PURPOSE: To provide a method of installing the construction for a buried tank which can reduce the working period from the reclamation up to the use of the tank.  
     CONSTITUTION: Tanks 1 and 2 already manufactured and assumbled at a ship- building yard or the like and moored with an anchor on the sea. Then, for example, when the dredging is completed within partitions installed to compart the ocean, the tanks are towed by a ship and carried into the partitions. After they are sunk by pouring sea water or the like thereinto, dredged or carried soil fills the partitions to reclaim. In this case, the land thus reclaimed has a high water content subsurface because of a high level of underground water, which is unable to be used as a land as it is. To solve the problem, the surface layer 10 of the subsoil is chemically improved with a soil hardening agent to upgrade the earth strength, and then, superlaid with ordinary soil.

Abstract: PURPOSE:To detect accurately an optical input by providing the 2nd peak detector detecting the amplitude of an amplified signal from a filter and a comparator comparing the output of the 2nd peak detector with a reference voltage. CONSTITUTION:An output of the peak detector 4 detecting the amplitude of an output voltage Vout is amplified by an amplifier 5, fed back to an automatic gain control amplifier 3 so as to keep the amplitude of the output voltage Vout independently of the level of the optical input Vs. On the other hand, the noise component at the outside of the signal band in the output voltage Vout is extracted by a filter 6 and amplified by an amplifier 7, then the noise level is detected by the peak detector 8 and the noise level is compared with the reference voltage Vref by the comparator 9. When the level exceeds a prescribed level, the comparator 9 outputs an output signal Vdet representing the missing of the optical input Vs. Thus, the missing of the optical input is detected easily and the optical input is detected accurately.

Abstract: PROBLEM TO BE SOLVED: To produce a highly rigid cement having high compression strength, tensile strength, flexural modulus, and the like, by mixing an admixture comprising corundum of alumina containing chromium oxide or cobalt oxide, a gel of silicic acid and a glucose, with a cement. SOLUTION: This highly rigid cement contains corundum of alumina, a gel of silicic acid and a glucose as an admixture. The very hard and chemically stabilized corundum having crystals arranged in the constant direction is obtained by melting alumina containing chromium oxide and cobalt oxide and cooling the melted alumina. A water glass is obtained by adding water to sodium silicate obtained by melting silicon dioxide in the coexistence of a base, and heating the obtained mixture. A dilute hydrochloric acid is added to an aqueous solution of the water glass, and the resultant mixture is shaken to provide a gel. The obtained gel is dried to provide a xerogel, and the obtained xerogel is formed into a powder. The glucose is obtained by hydrolyzing a starch.  The cement has reducibility and strong adhesion because the crystal of the glucose becomes an equilibrium state of alpha-glucose, beta-glucose and linear glucose, and aldehyde group is present.
