Abstract:
Hydrogen sulfide is dehydrogenated to generate a HS group and an S group. The HS group is oxidized to generate sulfuric acid, which is bonded to a metal. The S group is polymerized with a CH3S group to generate methyl trisulfide or methyl tetrasulfide, which is adsorbed to an adsorbent. Methyl mercaptan is dehydrogenated, for example, to generate a CH3S group. A portion of the CH3S group is oxidized to generate methanesulfonic acid, which is bonded to a metal. Another portion of the CH3S group is polymerized with the CH3S group itself to generate methyl disulfide, at least a portion of which is adsorbed to an adsorbent. Still another portion of the CH3S group is polymerized with the S group to generate methyl trisulfide or methyl tetrasulfide, which is physically adsorbed to an adsorbent. In this manner, malodor components including hydrogen sulfide and methyl mercaptan can efficiently be removed without producing or release of harmful secondary products. A simple-structure, compact deodorizing apparatus including appropriate metal oxide catalyst and an adsorbent material suitable for achieving the above deodorizing functions is incorporated in a toilet bowl.
Abstract:
This invention has as its object to provide a method and apparatus for controlling a vehicle air conditioner, which can obtain a combination of an outlet air flow rate V.sub.a and an outlet air temperature T.sub.o, which is desirable for comfort of a passenger, under a condition of air-conditioning control based on a heat balance equation. In order to achieve this object, this invention provides a method of controlling a vehicle air conditioner, including the first step of obtaining, from a heat balance equation, a plurality of combinations of the outlet air flow rates V.sub.a and the outlet air temperatures T.sub.o necessary for maintaining the passenger room temperature to be a predetermined target temperature, the second step of calculating comfort indices each representing the comfort level of a passenger on the basis of state amounts of factors which influence comfort felt by the passenger in the passenger room, and the plurality of combinations of the outlet air flow rates V.sub.a and the outlet air temperatures T.sub.o obtained in the first step, and the third step of searching a combination of the outlet air flow rate and the outlet air temperature, which can provide a comfort index closest to an optimal value of the comfort indices calculated in the second step.
Abstract:
An air conditioning control method of a vehicle includes the step of determining a target temperature of a passenger compartment of the vehicle, calculating a comfort index provided as a function of at least an outlet air temperature and outlet air volume flowing out of a heater-air-conditioner system in which air is treated to be introduce to a passenger compartment, setting a target comfort index, determining an optimized combination of the output air temperature and the output air volume which minimizes a deviation of the comfort index from the target comfort index, compensating the target temperature to reduce the deviation when the deviation is greater than a predetermined value. The optimized comfort level can be accomplished quickly through the control.
Abstract:
A method of and an apparatus for indicating a remaining fuel quantity for vehicles, designed to digitally indicate the quantity of fuel remaining in the fuel tank of a vehicle. The method of and the apparatus for repeating the operations of performing sampling detection of an amount of fuel remaining in the fuel tank of a vehicle, determining a center value for a plurality of remaining fuel quantity values detected by a microcomputer, determining limit values each thereof being apart from the center value by a predetermined amount, using any subsequent detected value exceeding the limit values as a new limit value, computing an average value of a predetermined number of detected sampling values, and indicating it on a display.
Abstract:
In a gasket of a cell comprising a marginal portion, an annular center portion and an intermediate portion integrally formed with each other, the intermediate portion of the gasket has an inwardly projecting annular thin wall surrounding the annular center portion with an annular space therebetween. The annular thin wall has, generally, an inverted frusto-conical shape and is provided at the outer surface thereof with an annular horizontal groove and a vertical groove intersecting with each other.
Abstract:
A sealing gasket of a cell comprises a circumferential marginal portion constricted between a metal casing and a terminal plate, a center collar through which a collector metal rod penetrates, and an intermediate portion integrally molded with the marginal portion and the center collar and having a thin wall portion tearable by a stretching force applied thereto. The center collar of the gasket is normally separated from the terminal plate but is movable toward the terminal plate by sliding on the collector metal rod in the event that the internal gas pressure within the cell is abnormally developed, whereby the thin wall portion of the gasket is stretched and torn to release the gas.
Abstract:
In an alkaline battery hermetically sealed by fusion of an insulator containing silicon oxide such as glass interposed between an annular metal cover electrically connected to one electrode of the battery and a metal member connected to the other electrode of the battery, an annular packing is disposed inside the annular metal cover in abutment therewith, and a metal collector plate is connected to the metal member and disposed below the insulator. The peripheral edge of the metal collector plate is tightly held against the inner periphery of the packing to define a closed space between the insulator and the collector plate.
