The present invention provides a golf ball with preferred hit feeling, controllability and satisfactory level of flying performance and cut resistance. The golf ball comprises a core and a cover covering the core, wherein said cover is mainly made of a mixture composed of an ionomer resin and a diene type rubber at a weight ratio (ionomer resin:diene rubber) of 95:5-60:40 and said diene type rubber is crosslinked by a crosslinking agent.

A surface acoustic wave resonator has a plural number N of interdigital transducers arranged in a sequence on a piezoelectric substrate to generate N surface acoustic wave signals with a predetermined frequency f.sub.0 and having phase difference of 2.pi./N radian therebetween. Oscillation circuits are individually connected to the N interdigital transducers and generate N oscillation signals with the same frequency f.sub.0 and having phase difference of 2.pi./N radian therebetween. These oscillation signals are multiplied together to generate a signal with frequency N times the predetermined frequency f.sub.0.

An output correction method for a proportional-output type O.sub.2 sensor including an oxygen concentration detecting element formed by an oxygen-pumping element and a cell element, each of the oxygen-pumping element and the cell element being composed of a wall of a solid electrolytic material having oxygen ion-conductivity, and a pair of electrodes having the wall interposed therebetween. The oxgen-pumping element is supplied with an output voltage corresponding to a difference between a voltage developed between the electrodes of the cell element and a predetermined reference voltage, and current flowing in the oxygen-pumping element is detected. A correction resistance supplies information indicative of a deviation of an air-fuel ratio detected by the sensor with respect to a predetermined reference air-fuel ratio. A correction value is determined on the basis of the information and the direction of flow of the current. The detected current is corrected by the use of the determined corrected value. A desired air-fuel ratio is calculated on the basis of the corrected current.

An apparatus for producing an oxygen enriched gas having a compressor for supplying air under pressure, a unit for producing a gas enriched with oxygen from the air supplied from the compressor, a gas storage tank for reserving the oxygen enriched gas produced from the producing unit, a flow rate setting unit to set a flow rate of the oxygen enriched gas delivered from the gas storage tank, and a regulating unit for adjustably regulating an oxygen concentration of the oxygen enriched gas in response to a change in a requirement of an oxygen concentration of the oxygen enriched gas obtained at an outlet of the apparatus.
摘要:
A method for controlling the flow rate of supplementary air supplied to an internal combustion engine via at least one supplementary air passage bypassing a throttle valve arranged in the intake air passage, by means of at least one control valve arranged across the at lease one supplementary air passage. The valve opening of the control valve is decreased with a decrease in the engine rotational speed, when the throttle valve is detected to be in a substantially fully closed position and at the same time the engine rotational speed is higher than a predetermined value which is higher than an idling speed of the engine. Preferably, the at least one supplementary air passage comprises a plurality of air passages, and the at least one control valve comprises a plurality of on-off valves arranged across respective ones of the air passages. One or more of the on-off valves are selectively opened in response to the extent of engine warming-up and/or an increase in engine load.
摘要:
A fuel supply control method for internal combustion engines, which is capable of stabilizing the engine rotational speed to a desired idling speed immediately after the rotational speed of the engine at idle suddenly changes due to an external disturbance such as a change in the electrical load on the engine. The fuel quantity to be supplied to the engine is determined in accordance with operating conditions of the engine in the idling condition, and the determined fuel quantity is corrected by a correction value which is determined in response to the difference between a desired idling speed of the rotational speed of the engine and an actual value thereof. When the absolute value of a detected rate of change in the rotational speed of the engine is larger than a predetermined value, the correction value is corrected to thereby correct the determined fuel quantity.
摘要:
An apparatus for piling rod-shaped articles in a container, in which a hopper member having at least one levelling means such as a swing pin is employed in combination with a push means. The rod-shaped articles temporarily collected in the hopper member are pushed out into the container by the push means at least every one layer thereof thereby to make an orderly pile of the rod-shaped articles in the container.
摘要:
In a stratification operation, O2 is injected from an oxygen injector during valve opening of an intake valve. Therefore, the injected O2 flows into a combustion chamber immediately after the injection, and forms a layer having a constant spread in the combustion chamber. Meanwhile, the working gas in the combustion chamber forms such a layer as to cover the O2 layer on a wall surface of the combustion chamber in conjunction with formation of the O2 layer. In other words, in the combustion chamber, an inner layer with a high O2 concentration and an outer layer with a high working gas concentration are respectively formed.
