IPC: G01B11/00
Filed: 2008-06-25
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a thermal chamber which houses a measuring apparatus becoming large for the reason of a stage becoming large for mounting a substrate according to a recent tendency toward making a substrate large-size, needs to enlarge its temperature control unit in order to maintain a temperature performance for a space in a blast booth, since the inner volume of the space becomes large, and so an atmosphere capacity required for controlling temperatures is made large.  <P>SOLUTION: The thermal chamber has a structure in which the blast booth of the thermal chamber is supported by a support clasp projecting from a stage part, a trestle of the measuring apparatus, and only a stage part above a stony bed is kept at a constant temperature.

Abstract: <P>PROBLEM TO BE SOLVED: To make setting of the number of persons scheduled to be imaged unnecessary, and to record an image captured when the number of persons to be captured included in an image capturing range has changed.  <P>SOLUTION: A CPU 2 detects faces of persons included in an image captured by an image capturing part 1 to count the number of faces in response to detection of a full depression operation of a shutter button. Then, the number of counted faces is stored in a predetermined region of a memory part 3. After that, the CPU 2 detects the faces included in the captured image again, and counts the number of faces. When the number of counted faces is equal to or less than the number of faces stored in the predetermined region of the memory part 3, the CPU 2 repeats processing for detecting the faces included in the captured image to count the number of faces. At the same time, when the number of counted faces exceeds the number of stored faces, the captured image is recorded in recording media 5 after lapse of a predetermined time.  <P>COPYRIGHT: (C)2010,JPO&INPIT

Title: Detection method of detecting temporal change generated when contact fatigue damage is generated
Inventor: MATSUBARA YUKIO
IPC: G01M13/00
Filed: 2008-07-02
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that data obtained by comparing signals output from a component in which damage is generated in advance and a component without damage are used as an index indicating the occurrence of contact fatigue damage, because it takes time to detect the change point, i.e. a signal indicating the change, generated in the component at the moment of the occurrence of contact fatigue damage in the component having a contact part regarding power transmission of a motor vehicle or the like.  <P>SOLUTION: After hydrogen is charged into the component, rolling contact fatigue test is performed with conditions similar to the actual use conditions of the component, and the temporal change of the signal arising from the component is detected. Thus, the change point, i.e. the signal indicating the change, generated in the component at the moment of the occurrence of contact fatigue damage is precisely detected more efficiently in a shorter time than in a case in which hydrogen is not charged into the component.  <P>COPYRIGHT: (C)2010,JPO&INPIT
