Obtained is a passenger conveyor that, in the case of the elongation of a step chain of the passenger conveyor, causes a hydraulic cylinder to move a lower-part step chain wheel, thereby absorbing a slack in the step chain and tensioning the step chain with any push-out force. In a passenger conveyor provided with a step chain tensioning device that, in the case of the elongation of a step chain, causes a lower-part step chain wheel to move, thereby absorbing a slack in the step chain and tensioning the step chain with any tensioning force, the step chain tensioning device includes a tensioning device section, which has a hydraulic cylinder and pushes out the lower-part step chain wheel with a push-out force of the hydraulic cylinder on a side where the step chain is tensioned, and a pressure device section, which has a pressure piston to which a load by a weight is applied and causes the hydraulic cylinder of the tensioning device section to constantly give any tension to the step chain via a hydraulic oil due to the pressure of the pressure piston.

摘要:
An SOI layer is formed on a substrate of a semiconductor device, and one or more elements are formed on the SOI layer. One or more grooves are formed in a substrate of the semiconductor device by removing part of the substrate. The groove is formed directly below an element for which dielectric loss caused by the substrate is assumed. Because silicon crystal constituting a dielectric is only present thinly at the groove or is completely absent therefrom, the dielectric loss of the element located above this groove is then very small. If this element is a constituent element of a high frequency circuit, the high frequency circuit thus displays high responsiveness and stability with respect to high frequency signal processing.

In a disk array apparatus which includes disk units so as to have a redundancy and which carries out, in response to a data writing instruction or a data reading instruction from a host computer, a data writing operation or a data reading operation between the disk units and the host computer, detector/memory section (211) detects, as a faulty unit, one of the disk units in which an abnormality occurs on any one of the data writing operation and the data reading operation. A disconnection managing section (212a) temporarily disconnects the faulty unit as a temporarily disconnected unit to make the disk array apparatus operate in a temporary degenerate mode. An instruction-execution controlling section (212) forces the disk units except the temporarily disconnected unit to execute the data writing operation or the reading operation between the disk units except the temporarily disconnected unit and the host computer by the use of the redundancy when the disk array apparatus receives, during the temporary degenerate mode, the data writing instruction or the data reading instruction from the host computer. A retry section (212c) carries out retry for the temporarily disconnected unit in parallel to the data writing operation or the data reading operation executed between the disk units except the temporarily disconnected unit and the host computer.

There is disclosed a laser beam output optical unit adjustment method and apparatus, which can perform inspection and adjustment of a laser beam unit and a laser scanning optical system including this unit used in a laser beam printer within a short period of time. The laser irradiation position is roughly adjusted using a wide-field position detector, and focus rough adjustment is then performed using a narrow-field position detector. Thereafter, fine adjustment of the irradiation position and focus fine adjustment are performed using the narrow-field position detector. An image enhancement tube capable of a high-speed gate operation is arranged in a laser scanning region, and instantaneously takes a beam spot during laser scanning. An image processing devices analyzes the taken spot image, and a calculation unit calculates various data.
