摘要： The present invention is directed to a production method for a nitride compound semiconductor element including a substrate and a multilayer structure 40 supported by an upper face of the substrate. First, a wafer 1 to be split into individual substrates is provided. A plurality of semiconductor layers composing the multilayer structure 40 are grown on the wafer 1. By cleaving the wafer 1 and the semiconductor layers, a cleavage plane in the multilayer structure 40 is formed. In the present invention, a plurality of voids are arranged at positions in the multilayer structure at which a cleavage plane is to be formed. Thus, cleavage can be performed with a good yield.

摘要： An assembly (20) for controlling movement of an automatically moveable door panel (22) includes a sensor (30, 32, 34) positioned on at least one of a door panel (22) or a door frame member (24, 26). The sensitive portion provides an indication of when an object is in contact with or in very close proximity to a sensitive portion. A sensitive portion is established over an area of the door or door frame member at which an object may become caught during automated door movement. A disclosed example includes using an electromechanical film as a sensor so that the sensitive portion is responsive to pressure applied by the object on the sensitive portion. Another disclosed example includes a field effect sensor that generates an electric field that is at least partially interrupted when an object contacts or comes in very close proximity to the sensitive portion. Automated movement of a door is controlled responsive to an indication of the presence of an object in a location where the object may become caught during automatic movement of the door.

摘要： To provide a double-deck elevator characterized by the fact that by increasing the story height adjustment range in the direction in which the two cars approach each other, it is possible to increase the degree of building design freedom. Two up/down cars (6), (7) arranged in outer frame (5) are connected with each other by means of pantographic mechanisms (11) that can effect an expansion and contraction operation, and the two cars (6), (7) are driven to move towards each other or away from each other by means of pantographic mechanisms (11). The pantographic mechanisms (11) are arranged in the spaces between vertical beams (5a) and the two cars (6), (7) and each has a pivot point at the longitudinal central portion of vertical beams (5a) extending vertically in outer frame (5). Due to the pantographic mechanisms (11), the story height adjustment range in the direction in which the two cars (6), (7) approach each other is not restricted.

摘要： It is to provide an optical disc recording apparatus and a recording power control method that are adapted to high-speed recording and can set an optimal erasing power with high accuracy. A test writing signal detector reproduces a test writing signal of a predetermined mark length or space length with varied power, and detects the number of error mark signals and an amplitude value of an envelope. A controller obtains a first threshold Pe0 of the erasing power based on the number of error mark signals in a region where laser power is low, and obtains a second threshold Pe1 of the erasing power based on the amplitude value in a region where the laser power is high. Then, the controller sets an optimal value of the erasing power from an average value of the first and second thresholds.
