    摘要： An object is to provide a method and a system for improving a residual stress in a tube body, with which the residual stress can reliably be improved without heating excessively. From an irradiation start angle θs to a first predetermined angle θ1 on the tube body, an intensity of a laser beam is gradually increased from 0.5 to the steady output of 1.0 output ratio; from the first predetermined angle θ1 to a second predetermined angle θ2, the intensity of the laser beam is set at 1.0 output ratio; from the second predetermined angle θ2 to an irradiation end angle θe, the intensity of the laser beam is gradually decreased from the 1.0 output ratio to 0.5; and at the irradiation end angle θe, the intensity of the laser beam is set to 0. All these steps are performed at one turn of rotation in the method and the system for improving residual stress in the tube body.

    摘要： An object is to provide a method and an apparatus for improving a residual stress in a tubular body, which are enabled to improve the residual stress reliably by clearly defining controlling rage for treatment conditions without depending on an installation state and configuration of the tubular body.

    摘要： A multiple-channel load driving apparatus has a plurality of driver circuits supplying drive currents individually to a plurality of loads. Of those driver circuits, at least one limits or stops the output thereof not only if an abnormality occurs in itself but also if an abnormality occurs in any other driver circuit. This configuration allows coordinated abnormality protection among the individual driver circuits, and thereby improves the safety and reliability of the load driving apparatus.

    摘要： An LCD panel module includes a common boosting converter, an LCD boosting circuit, an LDO control circuit, and constant current circuits for parallel-connected LED elements and series-connected LED elements. The LCD panel module is so configured that a type-switching unit can switch over between Type 1 in which the LED elements are connected in parallel and Type 2 in which the LED elements are connected in series. The common boosting converter preliminarily boosts a battery voltage supplied from a lithium ion battery to a low voltage or a high voltage and supplies the boosted voltage to the parallel-connected LED elements or series-connected LED elements respectively. The LCD boosting circuit boosts the low voltage and supplies it to an LCD panel, while the LDO control circuit steps down the high voltage and supplies it to the LCD panel.
