Abstract: An information searching system includes an encoding apparatus and a searching apparatus. The encoding apparatus inputs information to be stored, encodes the input information in layers, and then stores the resulting per-layer encoding information in a database. The searching apparatus acquires information that has been thus encoded in layers in order from the upper layers thereof, compares the encoded information for an acquired search query to the encoded information for potential matches on a per-layer basis, decodes the information for the potential matches that resemble the search query on the basis of the comparison results, and then outputs the decoded information for the potential matches that resemble the search query. In so doing, searches are conducted rapidly and with reduced computational load.

Abstract: A steam re-compression vacuum dryer includes a vacuum tank for accommodating waste; a first steam duct for removing steam from the vacuum tank; a steam compressor for compressing steam removed from the vacuum tank via the first steam duct and for producing a vacuum pressure in the vacuum tank; a steam condenser disposed in and/or thermally coupled to the vacuum tank; a non-condensing gas exhausting device for automatically exhausting non-condensing gas from the steam condenser; and a condensation water exhausting device for automatically exhausting condensation water from the steam condenser. If desired, a gas heater can be provided on the first steam duct to heat gas withdrawn from the tank through this duct. This gas heater may use steam discharged from the steam compressor as a heat source. The steam condensing device can be disposed in the vacuum tank, or it can be integral with an outer surface of the vacuum tank (e.g., the tank wall may have a double wall construction).

Abstract: A cooling tank 1 for cooling water 2b by bringing water 2b in direct contact with hardly-water-soluble refrigerant 2c having a larger specific gravity than that of water, which tank 1 has an inside space 3 above water surface in the tank 1 and the pressure P.sub.t of the space 3 is kept below the saturation pressure P.sub.0 of the refrigerant 2c at water freezing point (P.sub.t .ltoreq.P.sub.0). The tank 1 also has a refrigerant extraction hole 6a for extracting gas-phase refrigerant 2c, an outlet 14a for drawing cooled water 2b, and an upward passage 30 for refrigerant extending from the bottom of the tank 1 to the water surface therein, which passage 30 guides ascension of that refrigerant 2c which settles at the tank bottom toward the space 3 above the water surface.

Abstract: An ice making refrigerant mainly consists of at least one compound selected from the group of normal perfluoropentane, cycloperfluoropentane, isoperfluoropentane, and fluorohydropentane. The refrigerant may also consists of pentane mixed with a sufficient amount of one or more of the above compounds for making the refrigerant substantially incombustible. The refrigerant is highly resistant to combustion and free from destroying the stratospheric ozone layer. Ice is produced by mixing the refrigerant in liquid phase with water at a pressure higher than the saturation pressure P.sub.0 of the refrigerant for 0.degree. C. and then ejecting the water-refrigerant mixture into a tank at a pressure below the above saturation pressure P.sub.0, so as to evaporate the refrigerant and let the water freeze by the latent heat of evaporation of the refrigerant.

Abstract: The method stores heat in ice by freezing water through its direct contact with a hardly-water-soluble refrigerant; i.e., water is mixed with the refrigerant at a high pressure to produce a liquid mixture while preventing evaporation of the refrigerant, and the liquid mixture is jetted from a nozzle into a space at a lower pressure, whereby the refrigerant evaporates at the lower pressure and the water in the liquid mixture is frozen into sherbet-like ice and dispersed over a wider area than in the case of non-sherbert-like ice. A device based on the method uses a heat-insulating water tank whose top space above water level therein is kept at a pressure P2 lower than saturation pressure P0 (P2<P0) of the refrigerant for water freezing point 0.degree.C. A mixer mixes the refrigerant of liquid phase and water at a pressure P1 which is higher than the saturation pressure P0 of the refrigerant for water freezing point 0.degree.C.

Abstract: An ice storage refrigerating apparatus of direct contact type comprises a closed crystallizer tank containing water therein and a refrigerant circulating system. A refrigerant consisting essentially of a hydrocarbon having four carbon atoms and/or a hydrocarbon having five carbon atoms is brought into direct contact with the water contained in the crystallizer tank to form ice in sherbet form which is used for heat exchange to provide chilled water used for air conditioning.

Abstract: A method of forming clathrate ice in a supercooled water-based liquid contained in a vessel is disclosed. Initially, an oscillator device is located in the liquid in the vessel. The oscillator device is then oscillated ultrasonically so that small crystals are formed in the liquid. These small crystals serve as seed crystals for ice formation in the liquid and thereby prevent supercooling of the liquid. Preferably, the oscillating device is controlled by a thermostat which initiates operation of the oscillator device when the temperature of the liquid is lowered to the freezing point. Thereafter, the operation of the oscillator device is terminated when ice is sensed in the liquid by an ice sensor.

Abstract: An ignition apparatus for internal combustion engines for preventing input noises out of an ignition signal line from affecting the ignition timing of the engine to make knocking or a start malfunction. A bistable circuit is provided for eliminating such input noises. The bistable circuit is associated with a Schmitt circuit which serves to energize or de-energize an ignition coil for inducing a discharging voltage. The Schmitt circuit is overridden by the bistable circuit for a time interval corresponding to a time for which such input noises exist. Afterwards, the Schmitt circuit receives as an input the ignition signal synchronizing with an engine speed and controls the ignition timing.

The casing has an open end or face in which the core is mounted in proximity to an engine driven rotor. The interconnecting leads between the coil and substrate board include terminal plates 6 and short straps 7 to avoid spurious high frequency radiations and induced signals.
