Title: Method and device for measuring temperature distribution
Inventor: YANO KENJI
IPC: G01J5/60
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To provide a device for measuring temperature distribution capable of measuring a surface temperature of a measured member with high accuracy. SOLUTION: The device for measuring temperature distribution 10 uses a first filter 34 for passing light of a wavelength selected from a high radiation area, which is higher than radiation intensity EBG at the room temperature, of a radiation intensity curve L1 corresponding to the wavelength of a blackbody at an approximately lowest temperature in a range of measured temperature in the temperature distribution, and a second filter 36 for passing light of a wavelength which is shifted from a first wavelength λ1 so that the wavelength is not more than one-third of the first wavelength λ1 and has a wavelength difference not less than the sum of a half-width Δλ1 of the first wavelength λ1 and a half-width Δλ2 of a second wavelength λ2 . Accordingly, a signal with sufficient radiation intensity is obtained, its S/N ratio becomes high, and light of the first wavelength and light of the second wavelength which are adjacent each other are obtained so that a prerequisite of a measurement principle of a two color thermometer that 'the wavelength dependence on the emissivity can be ignored in two adjacent wavelengths and emissivity can be approximated by ε1 =ε2 ' is surely established, and highly accurate temperature distribution can be obtained.

Title: Grain quality evaluating device
Inventor: HONGO ARATA
IPC: G06T1/00
Filed: 2001-04-10
Abstract: PROBLEM TO BE SOLVED: To automatically evaluate grain quality by mechanization. SOLUTION: The picked-up images of grain appearance of the front and back surfaces of grains picked up by image pickup means are recorded by a recording means. An analyzing means obtains recorded images from the recording means, divides the grain images of every piece into a plurality of quadrants, and analyzes each individual quadrant. The results of analysis are arithmetically processed by Mahalanobis analysis dependently on each quadrant to obtain the results of evaluation on the logical sum of its front and back. A quality display is added to the grains, or the grains are divided into previously specified classifications according to the results of evaluation.  When the image pickup of the image pickup means includes front and back transmitted light images from at least one direction, the processing of the analyzing means is limited to the center parts of the grains in the longitudinal direction and performed only on crack detection.

Title: Led lamp
Inventor: TAKAHASHI YUJI
IPC: H01L25/18
Filed: 2001-04-12
Abstract: PROBLEM TO BE SOLVED: To reduce the thickness of the opening and the outside shape of a case of a LED lamp, increase its brightness and realize a superior radiability. SOLUTION: In bending the lower ends of leads 3b,..., 3f backwards, not only lead supporting parts 2e but also cuts 2b at the top end of an opening 2a can receive a stress exerted on a case 2 and hence there is no fear of breaking the lead supporting parts 2e, if their thickness is reduced, thus reducing the thickness of the case. Red light emitting elements R1, R2 take their p-sides as light emitting surfaces to increase the brightness. Green light emitting elements G1, G2 and a blue light emitting element B1 are mounted in a flip chip structure through Zener diodes ZD1, ZD2, ZD3 with a sapphire substrate taken as a light emitting surface, thus increasing the brightness. Wires 4 interconnect the elements to form anode-common circuits, this reducing the thickness of the opening 2a. The leads 3b,..., 3f mounting the elements are independent to make the radiability superior.

Title: Imaging device
Inventor: SAKURAI JUNZO
IPC: H04N5/341
Filed: 2001-04-23
Abstract: PROBLEM TO BE SOLVED: To enhance the S/N ratio of an imaging signal by preventing the inflow of a dark current, from a vertical transfer path VCCD to a photodiode PD. SOLUTION: In order to prevent charges from being held over a long time beneath a vertical transfer electrode V2 adjacent to a photodiode PD, a positive middle voltage M is applied to vertical transfer electrodes V3 and V4, and a negative low voltage L is applied to vertical transfer electrodes V2 and V1 during a horizontal transfer interval. Consequently, charged are stored in a potential well formed beneath the vertical transfer electrodes V3 and V4, but no potential well is formed beneath the vertical transfer electrodes V2 and V3, and a potential barrier is formed. Inflow of dark current from a VCCD to a PD can be prevented, by employing a drive system for vertically transferring a line of signal charges for each blanking interval, while storing/holding signal charges not in the electrodes V3 and V4, but rather than in the electrodes V2 and V1.
