    • A stylus for a capacity change detection type disc system which reads information signals such as audio or video signals out of a track which is formed in a disc surface as an arrangement of pits corresponding to the information signals has a body portion which is made of a diamond. Argon plus ions are implanted in the stylus body portion from the surface of the diamond portion to graphitize the diamond to provide a conductive layer which serves as a detecting electrode portion. The graphitizing rate is highest at the surface portion of the electrode portion which consists of the formed conductive layer. The graphitizing rate changes from the surface portion toward a portion remote from the surface portion, where the graphitizing rate is lowest, with a variation rate smaller than that of the graphitizing rate which would result from a single implantation of ions into the diamond.

    • A multi link type piston-crank mechanism comprises an upper link that has one end pivotally connected to a piston of the engine through a piston pin, a lower link that is pivotally connected to the other end of the upper link through an upper pin and rotatably disposed on a crank pin of a crankshaft of the engine; and a control link that has a base end part swingably held by a body of the engine and a leading end pivotally connected to the lower link through a control pin. An axis of the piston pin is offset relative to an axis of the piston in thrust and counter thrust directions. When the piston comes to BDC, a part of the piston takes a position below a lower edge of a corresponding cylinder of the engine and the upper pin is offset relative to the axis of the piston pin in the same direction as a pin offset direction in which the axis of the piston pin is offset in the thrust and counter thrust directions relative to the axis of the piston.

    • Provided is a fuel cell system which can properly control a refresh operation. A controller controls the refresh operation so that an output voltage does not exceed an avoidance voltage even after the refresh operation. Specifically, the controller estimates the output voltage after the refresh operation from the output voltage before the refresh operation and controls execution of the refresh operation so that the estimated output voltage after the refresh operation does not exceed the avoidance voltage. For example, if before the refresh operation, when judging that the estimated output voltage after the refresh operation does not exceed the avoidance voltage, the controller executes the refresh operation.
    • 提供了可以适当地控制刷新操作的燃料电池系统。 控制器控制刷新操作,使得即使在刷新操作之后输出电压也不超过回避电压。 具体地,控制器从更新操作之前的输出电压估计刷新操作之后的输出电压,并且控制刷新操作的执行,使得刷新操作之后的估计输出电压不超过回避电压。 例如,如果在更新操作之前,当判断刷新操作后的估计输出电压不超过避免电压时,控制器执行刷新操作。

    • In a reciprocating piston engine employing a variable compression ratio mechanism linked to a reciprocating piston for variably adjusting a geometrical compression ratio by varying at least a piston top dead center position, so that the top dead center position obtained at a low geometrical compression ratio is set to be lower than that at a high geometrical compression ratio, responsively to a controlled variable, a controller is configured to set a target compression ratio to a high value at low engine load operation, and to a relatively low value at high engine load operation. A substantially entire area of a crown of the piston, defining a part of a wall surface of a combustion chamber, is formed of a non-metallic material having a higher heat-insulating and heat-reserving property as compared to a base structural material of each of the combustion chamber and the piston.
