Title: Method for measuring diameter of rivet of can lid
Inventor: TAKEDA HIROSHI
IPC: G01B11/08
Filed: 1986-12-17
Abstract: PURPOSE:To automatically perform highly accurate measurement, by a method wherein a can lid is placed on a turntable and the rivet part of the can lid is illuminated from above by ring-shaped diffused light and photographed by a camera. CONSTITUTION:The rivet 6 of the can lid 2 placed on a turntable 1 is uniformly illuminated by the soft light due to the diffusion plate 5 provided to the under surface of a ring light 4. When the central upper part of the rivet 6 is photographed in this state by a video camera 3, the top surface of the rivet 6 becomes a white image and the outside part thereof becomes a black image to obtain an image having a sharp boundary part. This image is converted to a video signal and the diameter of the rivet 6 at a specific position is automatically operated by an image processor. This measured value is recorded and displayed on a monitor picture and the diameter of the rivet 6 can be read by the scale of said picture. Next, the turntable 1 is rotated by a required quantity to perform the same measurement and, even when there is an error in the rolling mesh direction of the can lid, more precise measurement can be performed.

Title: Optical fiber lighting device
Inventor: SUDA MANABU
IPC: G02B6/00
Filed: 1996-10-24
Abstract: PROBLEM TO BE SOLVED: To use the device to light up an instrument, etc., by arranging a light source in contact with one end of an optical fiber, and providing frosted glass type unevenness on the outer peripheral surface of the optical fiber to its overall length and guiding light out. SOLUTION: The surface of the optical fiber 1 is formed into a lusterless uneven surface like frosted glass to provide the uneven surface 2. The light source is fitted to one end of the optical fiber 1 by using light source fittings 3 and electric power is applied through a lead wire 4. A reflecting plate 5 which totally reflects light is fitted to the other end. Thus, a light emission body for the optical fiber 1 is constituted. Namely, the outer periphery of the optical fiber 1 is frosted and then the light entering the optical fiber 1 is not only reflected, but also almost all transmitted through the uneven surface 2 since the outer peripheral surface which should reflect the light efficiency is uneven. Then the whole optical fiber serves as a light emission body to illuminate the outside.

Filed: 1994-12-02
Abstract: PURPOSE: To prevent electric leakage and break caused by adhesion of conductive ink and disconnection at an interface to an end face and an electrode of a base by a method wherein a laminated piezoelectric member is bonded to the base larger than the laminated piezoelectric member in width by insert-integral molding through a thermosetting resin material, and the other flat part of the base serves as a flat electrode-forming surface. CONSTITUTION: A laminated piezoelectric member 1 is bonded to a resin base 7 through an unsatd. polyester resin by insert-integral molding. The resin base 7 is larger in width than the laminated piezoelectric member 1 and is provided with angular holes 8 for aligning the base 7 in insert-molding. Holes 9 used for aligning in assembly are each formed outside the hole 8. The flat part of the base 7 on which the laminated piezoelectric member 1 is not overlapped serves as a flat electrode-forming part 16 later. The surface of the composite other than the lower surface is metallized. Since the laminated piezoelectric member 1 is bonded to the base 7 by insert-integral molding, a boundary 10 between the two is improved in airtightness and adhesion.  Therefore, ink or other water content does not penetrate through the boundary, and a conductive electrode can be metallized without disconnection at the boundary.

Title: Sheet carrying device and automatic document carrying device
Inventor: HIROSE AKIRA
IPC: B65H3/18
Filed: 1990-11-05
Abstract: PURPOSE:To obtain a sheet carrying device in which a belt is hard to be contaminated and which has excellent carrying performance by giving an electrostatic attraction to the carrier belt, allowing the carrier-belt to approach a sheet, and allowing the sheet to be attracted to the carrier-belt and held by it, by means of a connecting and separating means only when the sheet is carried and fed. CONSTITUTION:After document sheets S are loaded on a document loading table 15, the sheets S are set so that they can be carried, the number of the copy sheets is set by a document-operation display panel unit, and a copy start key is depressed. Simultaneously, a carrier-belt 12 is charged by a specified AC--voltage to generate a non-uniform electric field, and a pressing member 16 pushes the belt 12 against a sheet S on the document loading table 15 for the sheet S to be attracted to the belt, and then rises. At this time, the belt 12 attracting and holding the sheet S raises the attracted sheet S to separate it from other sheets S, and to feed the document sheet to a contact glass 13 side. On the other hand, electro static attraction caused by the non-uniform electric field completely attracts the sheet S abutting on the belt. Thus, the attracted sheet S is positively carried up to the glass 13, and thereby incorrect carrying of the sheet such as deviation of position, diagonal feed, etc., can be prevented.

Title: Method of and device for analyzing heartbeat fluctuation
Inventor: SHIMAZU MIKIO
IPC: A61B5/16
Filed: 1997-10-31
Abstract: PROBLEM TO BE SOLVED: To calculate at high time resolution the power of a frequency component involved in heartbeat fluctuation which takes the form of a non-stationary signal. SOLUTION: A heartbeat interval calculating part 102 obtains heartbeat interval time-series data which are at unequal time intervals, by calculating heartbeat intervals from biomedical signals measured with a biomedical signal measuring part 101. An equal-interval data originating part 103 originates heartbeat interval time-series data which are at equal time intervals, by interpolating and resampling heartbeat interval time-series data which are at unequal time intervals. A discrete binary wavelet converting pat 104 splits the heartbeat interval time-series data which are at equal time intervals into wavelet factors for a plurality of frequency bands through discrete binary wavelet conversion.  For each area of minimum time resolution corresponding to each of the frequency bands, each power calculating part 105a-105f calculates half the square of the maximum value of the absolute value of the wavelet factor as the power of that area. The fluctuation with time of the power of the frequency component involved in heartbeat fluctuation is thus calculated.
