Title: Target detecting apparatus
Inventor: NAKADA TAKESHI
IPC: G01S17/88
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To provide a target detecting apparatus in which a binarization processing operation can be simplified and by which a target can be extracted with high accuracy by a method wherein observed images, at different wavelengths, which are imaged in a visible near-infrared region are used and a difference is computed and processed on the basis of luminance information on a part selected by an operator in the respective observed images and on the basis of the observed images. SOLUTION: In an image which is displayed on a first image display part 15 in a target detecting and processing part, an operator operates a cursor displayed inside an image by using an image-coordinate position indication part 19 so as to select a part whose luminance level is low. In the same manner, a part whose luminance level is low is selected by a second image display part 18. At this time, in a target detecting apparatus, information in a first image memory 13 in which an image at a wavelength band (a) is recorded is input by a subtraction processing part 20, and luminance information on a part selected from luminance information on every pixel in the image is subtracted by an optical-path luminance subtraction processing operation at the wavelength band (a).  In the same manner, also a second image memory 16 performs a subtraction processing operation at a wavelength band (b). In a division processing part, the ratio of the value of the wavelength band (a) to that of the wavelength band (b) is computed by a ratio computing and processing operation so as to find the ratio of respective pixels, and it is compared with a threshold value by a binarization processing part 22 so as to stored in an image memory 23.

Title: Turbine
Inventor: WATANABE TADAAKI
IPC: F02B39/00
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To restrain peeling caused on an impeller of a turbine, to maintain efficiency in an extensive flow rate region and to miniaturize the turbine by providing the impeller having a vane provided with an overhung part or a cutout part having an angle of sweep back on a front edge. SOLUTION: Exhaust gas from an engine flows in a trubine casing 1 and flows in a turbine impeller 3 through a scroll 4. At the time when a turbine is driven at a design point, a relative inflow angle and an inlet blade angle of exhaust gas to the impeller 3 coincide with each other, and exhaust gas smoothly flows along an impeller vane 3a. At the time when the turbine is driven separated from the design point, there is made a difference between the relative inflow angle and the inlet blade angle, and when a flow flows in a front edge of the impeller 3a at a large angle of attack, a vortex growing from an overhung part 3b having an angle of sweep back or a cutout part is a screw type vertical vortex in aparallel with the flow, and a central axis is in parallel with the flow.  This vortex flow 6 strong and stable, supplies a flow high in total pressure to peeling caused on the overall vane and restrains a scale of peeling small.

IPC: F04C18/02
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To make the resistance to separation equal to a compressive separating force even if the operating condition of a compressor varies.

Abstract: PURPOSE:To improve an identification character for an object by using linear polarized light having a polarized surface in a specified direction as detection light, emitting detection light in a direction corresponding to an optical identification character, rotating the polarized surface by a prescribed angle and receiving only rotated linear polarized light through a filter. CONSTITUTION:When a card is carried to a place where an identification seal 3 is confronted with a light projecting/receiving unit 5, the identification seal 3 is irradiated with detection light from a light-emitting element 6 having the linear polarized surface in the specified direction. Then, it is doubly refracted by a hologram forming layer 11a, and refracted light reflected in a light- reflecting layer 11b is emitted in a direction corresponding to the refraction characteristic of a hologram as linear polarized light where the polarized surface is rotated by 90 degrees with respect to incident light. Then, light is received in one of the parts of a light-receiving element 7. When light which is made incident on the light-emitting element 7 is not linear polarized light having the polarized surface rotated by 90 degrees with respect to detection light having the linear polarized surface in the specified direction, it is cut off by the filter 9 and is hardly received by the light-receiving element 7.

IPC: H01M10/06
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To keep high rate discharge characteristic equal to or more than the conventional battery and at the same time improve the trickle lifetime. SOLUTION: By limiting the surface area per 20 hour rate capacity of a negative electrode plate to be 24-30 cm<2> /Ah, the trickle lifetime is improved, even if the conventional positive electrode grid alloy is used, and high rate discharge capacity is kept in the same level as the conventional battery. By limiting the surface area of the negative electrode, an oxygen gas absorbing reaction velocity is suppressed, and the amount of lead sulfate in the negative electrode produced by the oxygen gas absorbing reaction is reduced. Reduction current based on the reduction of lead sulfate in trickle charge is decreased, and trickle current can be made to decrease. As a result, the trickle lifetime is improved.
