Title: Optical distance-measuring apparatus
Inventor: WATANABE HIROTADA
IPC: G01B11/00
Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To prevent a measuring error that a distance of an object outside a measuring range is output as a value within the measuring range in an optical distance-measuring method based on the principle of triangulation. SOLUTION: A light is cast on an object to be measured, and a scattering light by the object is condensed onto a light receiving element by a photodetecting lens, whereby a distance to the object from the condensed point is measured in the apparatus. A plurality of position sensors of different resolutions are used for the light receiving element 22, for example, a position sensor 22a of a good positional resolution having a photodetecting face corresponding in size to a measuring range and a position sensor 22b which does not have a so good positional resolution, but is inexpensive or easy to use. Accordingly, the generation of an error to judge the distance as indefinitely far is eliminated.

Title: Material-testing machine
Inventor: HIRAKI HITOSHI
IPC: G01N3/08
Filed: 1999-07-16
Abstract: PROBLEM TO BE SOLVED: To automatically switch from load speed control to retention control by capturing a time point when the aging change rate of a displacement-detection result exceeds a prescribed ratio as the transition time point of a test piece from an elastic region to a plastic region for controlling a load mechanism. SOLUTION: Both the ends of a test piece are gripped by gripping tools 14a and 14b provided between cross heads 11a and 12a of fixed and movable frames 11 and 12, and the movable frame 12 is moved up by the drive of a hydraulic ram cylinder 13 for applying pull to the test piece. The load, the displacement of the movable frame 13, and the extension of the test piece are detected by a pressure cell 41, a stroke detector 43, and an expansion meter 45, respectively, and are taken in by a control part 30. The control part 30 uses the load detection data for the load speed control of the hydraulic ram cylinder 13.  Also, when a difference ΔL between the most recent and last displacement data of the movable frame 13 and displacement data difference ΔL' in the case of the previous data sampling do not satisfy ΔL>=αΔL' (α is a prescribed coefficient), it is judged that the sample piece is still in an elastic region, and load speed control is continued. On the other hand, when they satisfy the expression, it is judged that the test piece has entered a plastic regions, thus switching to retention control.

Filed: 1988-08-15
Abstract: PURPOSE:To prevent an insulation resistance between the input side of a light-emitting part and the output side of a photodetecting part from being deteriorated by a method wherein a gap produced between an internal resin composed of a transparent substance and a reflecting film and an external resin of a molding resin is filled with an insulating oil. CONSTITUTION:A light-emitting element 2 is fixed to a lead 1a of a lead frame 1 and is connected electrically to the lead 1a by using a gold wire 9a; an optical signal is emitted by an electrical signal supplied to the lead 1a. A photodetector 3 is fixed to the other lead 1b and is connected electrically to the lead 1b by using a gold wire 9b; when it receives an optical signal, it sends an electrical signal to the lead 1b. Then, a transparent substance 4 is formed so as to cover these leads and elements; in order to reflect light and to enhance optical efficiency, a white resin is arranged as a reflecting film 5 so as to cover the transparent substance 4 at its outside; its outside is resin-sealed with a molding resin 7. A gap generated after a molding operation at a boundary face of the reflecting film 5 and the molding resin 7 is filled with an insulating oil 10 through a small hole 8; after that, the small hole 8 is sealed hermetically by using a sealing material 11. Thereby, a part between the lead 1a and the lead 1b is bridged by a water film; this prevents that an insulation resistance is deteriorated.

Title: Device and method for recognizing voice
Inventor: MUROI TETSUYA
IPC: G10L17/26
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To accelerate the voice recognition speed by word spotting.
