摘要： The principal surface of a substrate made of a group III-V compound semiconductor material is about a (100) plane. A light emitting lamination structure is disposed on the principal surface. In the light emitting lamination structure, a quantum well layer is sandwiched by a pair of carrier confinement layers made of a semiconductor material having a band gap wider than a semiconductor material of the quantum well layer. The pair of carrier confinement layers are sandwiched by a pair of clad layers made of a semiconductor material having a band gap wider than the band gap of the semiconductor material of the carrier confinement layers. Thicknesses of the quantum well layer and the carrier confinement layers, as well as compositions of the semiconductor materials thereof, are set such that light emission recombination of electrons and holes occurs in the quantum well layer and not in the carrier confinement layers.

摘要： Each parameter is provided with increase/decrease switches and a slider. In a case where a user desires seamless rough control of the value of a target parameter, the user is to use the slider. In a case where the user desires easy control of the value of the parameter with the smallest unit of the resolution, the user is to use the increase/decrease switches. Since the slider specifies a parameter value in accordance with the position of the manipulated slider, the range within which the parameter value can change is determined on the basis of the current parameter value and the maximum value and the minimum value of the parameter. Because the increase/decrease switch increases/decreases a parameter value by “1” at each manipulation, the range within which the parameter value can change by a single manipulation of the increase/decrease switch is “±1”.
摘要翻译：每个参数都带有增减开关和滑块。在用户期望对目标参数的值进行无缝粗略控制的情况下，用户将使用滑块。在用户期望以最小的分辨率单位容易地控制参数的值的情况下，用户将使用增减开关。由于滑块根据操作滑块的位置指定参数值，所以基于当前参数值和参数的最大值和最小值来确定参数值可以改变的范围。由于增加/减少开关在每次操作时将参数值增加/减少“1”，所以参数值可以通过增加/减少开关的单次操作而改变的范围为“±1”。

摘要： A double-cylinder construction which can be used not only in large-sized compression molding machines but also in small-sized or medium-sized compression molding machines. In the double-cylinder construction of the present invention, a ram slidably fitted within an outer cylinder is provided in the center thereof with a hollow part. A rod slidably fitted in said hollow part is fixed to the bottom of said outer cylinder without penetrating said bottom thereof, and said rod does not contain an oil passage within. The double-cylinder construction always contains a certain amount of oil within and this self-contained oil is moved back and forth within the double-cylinder construction when the ram is being moved up and down. Therefore, the amount of oil supplied to the double-cylinder construction from outside is very small.

摘要： In a power supply device, the controller outputs a control signal specifying a voltage value. The voltage conversion unit converts a first voltage to a second voltage in response to a control signal specifying a voltage value output from the controller. The voltage conversion unit converts the first voltage to a start voltage, as the second voltage, in response to a first control signal specifying a start voltage value output from the controller and further converts the first voltage to a target voltage, as the second voltage, in response to a second control signal specifying a target voltage value output from the controller. A transition period of time is intervened between generation of the start voltage and generation of the target voltage during which the controller outputs a third control signal specifying the intermediate voltage value between the start voltage value and the target voltage value.
