摘要： A ring-shaped plate member (6) of a three-layer structure having an aluminium alloy material (8) disposed on the opposite sides of a copper alloy material (7) is formed by casting in the outer peripheral part (2) of a piston (1) made of an aluminium alloy where a piston ring groove (3) is to be formed. The ring-shaped plate member (6) and the piston (1) are joined integrally by remelting locally the junction part of the aluminium alloy material (8) of the ring shaped plate member (6) and the piston (1) by applying an electron beam thereto. Thereafter the piston ring groove (3) is formed in the copper alloy material (7) of the ring-shaped plate member (6). By this method, the piston for an internal combustion engine, such that the part of a hardened layer forming the piston ring is prevented from adhering to the piston ring and the hardened layer is prevented from cracking, is provided.

摘要： A capsule holder (2) of an intranasal medicator (1) is composed of an axially movable mobile member (8) and a fixed member (3), and on the outer periphery of the mobile member (8) is formed on external thread (8D) engaging with an internal thread (19C) of the drug spraying section (19). When a capsule (K) is pushed into a unilateral capsule pit (11), an air inlet (H1) is formed by a piercing tip (27A) of a pin (27). When the capsule holder (2) is screwed into the drug spraying section (19), the mobile member (8) is pulled up and the piercing tip (27A) is pulled out of the air inlet (H1). An air outlet (H2) is formed by a pin (28). The medicator (1) is provided with a built-in piercer to help the formation of the air inlet (H1) when the capsule (K) is pushed into the capsule pit. The medicator can be made compact as a whole, because the pins (27, 28) are designed to be short and the outer periphery of the capsule holder (2) is covered with a pump (15).

摘要： A device for detecting a vapourising rate of fuel to make appropriate volume adjustments for air-fuel ratio feedback control. When air-fuel ratio feedback control is started just after the start of an engine (S4), the temperature of exhaust gas is determined based on the temperature TW of cooling water (S5). When the exhaust gas temperature is low, a mean value alpha av of an air-fuel ratio feedback correction coefficient alpha is obtained (S6, S7), and the mean value alpha av is compared with a reference value (S8). When heavy fuel having poor vapourising properties is used, a large amount of HC is contained in exhaust gas. Since oxygen consumption increases accordingly, the control point of the air-fuel ratio feedback control expressed by the mean value alpha av is deviated toward the lean side. On the basis of this deviation, whether it is heavy fuel of slow vaporization or light fuel of fast vaporization is judged during air-fuel ratio feedback control (S9, S10).
摘要翻译：用于检测燃料的蒸发速率以对空燃比反馈控制进行适当的音量调节的装置。当发动机起动后开始空燃比反馈控制（S4）时，基于冷却水的温度TW来确定排气温度（S5）。当排气温度低时，获得空燃比反馈校正系数α的平均值αav（S6，S7），将平均值αav与基准值进行比较（S8）。当使用具有差的蒸气性质的重质燃料时，废气中含有大量的HC。由于耗氧量相应地增加，所以由平均值αav表示的空燃比反馈控制的控制点偏向瘦侧。在这种偏差的基础上，在空燃比反馈控制（S9，S10）中判断是否是缓慢蒸发的重质燃料或快速蒸发的轻燃料。

摘要： A method and an apparatus for learning a control value at the time of an internal combustion engine idling while performing a feedback control to bring an engine rotating speed to a target rotating speed. During a predetermined period of time after the manufacture of the engine, rapid learning rapidly eliminates a discrepancy between a control value and a target value, due to initial variations in terms of parts and terms, by setting a feedback control constant so as to increase a responsiveness and setting a large critical value for a feedback correction amount. Then for a gradually changing discrepancy between the control value and the target value due to deterioration of parts, friction of terms and so on, the learning is switched over to permit an ordinary, slow learning to be performed whereby an idling speed is rapidly and constantly converged into the target rotating speed on the basis of a favorable learned value.

摘要： A distance adjustable nozzle mechanism (25) is provided on a passage member (17) at portions on jetting sides of right and left chemical passages (20, 20). The distance adjustable nozzle mechanism (25) comprises fitting convex portions (26, 26) formed in the passage member (17), adjustable nozzles (27, 27) rotatably and detachably mounted to the fitting convex portions (26, 26), and tapered spray ports (28) communicating with the chemical passages (20) to extend along the fitting convex portions (26) and the adjustable nozzles (27), of which axes are eccentrically offset from an axis of rotation. Accordingly, upon the rotation of the respective adjustable nozzles (27), they move toward and away from each other by an extent of eccentricity from the axis of rotation, so that a nozzle pitch between the respective adjustable nozzles (27) can be simply regulated to match a distance between nasal cavities of a patient. Also, cleaning is made easy by dismounting the respective adjustable nozzles (27).

摘要： A fuel injection valve adapted to bring a fuel to be atomized injected from a fuel injection port into collision with supplementary air introduced from the outside, and accelerate the pulverization and atomization of the fuel is provided with injected fuel guide bores into which the fuel to be atomized is introduced in each of desired directions. Owing to this arrangement, the injected fuel from the fuel injection port impinges upon the supplementary air and the resultant mixture is introduced into the injected fuel guide bores as the pulverization and atomization of the fuel are accelerated, and the fuel diffusing and injecting direction is restricted by the inner surfaces of the injected fuel guide bores. Accordingly, the cross-sectional shape of the injected fuel is controlled to an optimum shape, and the deposition of the fuel on the inner surface of a suction port is reduced. Consequently, the fuel combustion condition can be improved, and , especially, the reduction of generation of HC and the improvement of fuel efficiency can be effected.

摘要： A refrigerant sensor adapted to generate an output in accordance with its quantity of contact with a liquid phase refrigerant is provided in an intermediate portion of a refrigerant circulating closed circuit in an air-conditioner, and the rotational speed of a compressor is detected, a judgement value set in accordance with this rotational speed and an output value from the refrigerant sensor being compared with each other to detect the shortage of the refrigerant. Owing to this structure, even when the liquid level of the refrigerant in the refrigerant sensor varies in accordance with an increase in the rotational speed of the compressor to cause an output the level of which is higher than that of an actual filling quantity of the refrigerant to be generated, a judgement value in proportion to this output level is set, and the shortage of the refrigerant can therefore be detected accurately. This can reliably prevent the occurrence of seizure, which is ascribed to the shortage of refrigerant, of the compressor.
