    摘要： A piston head block is provided with smaller exernal diameter at the portion where a cut-out for receiving a lubricant injection nozzle that remaining portion. With the smaller diameter, a clearance or gap is formed between the internal surface of an engine cylinder and the external surface of the smaller diameter portion. Therefore, during piston stroke, the smaller diameter portion, in which the lubricant injection nozzle receptacle cut-out is formed, becomes free from the transverse stress.

    摘要： There is provided an electric power applying circuit for applying a direct current power to a load. The electric power applying circuit includes an output buffer that (i) is supplied with, as power source voltages, positive and negative high voltages which are determined in accordance with a range of an applied voltage which is to be applied to the load, (ii) generates a voltage in accordance with an input voltage, within a range defined by the power source voltages, and (iii) applies the generated voltage to the load, a main amplifier that amplifies a voltage input thereto to generate the input voltage, and inputs the generated input voltage into the output buffer, wherein the main amplifier exhibits a higher accuracy in terms of voltage generation than the output buffer, and a floating power source that generates positive and negative floating voltages by using, as a reference, a voltage determined in accordance with a voltage output from the output buffer, and supplies the generated positive and negative floating voltages to the main amplifier as power source voltages thereof, wherein a difference in voltage between the positive and negative floating voltages is smaller than a difference in voltage between the positive and negative high voltages.
