Filed: 1987-07-27
Abstract: PURPOSE:To improve the sensitivity of a detector by providing a junction field- effect transistor for using only a single gate in the input stage of a current- voltage converter for converting a current signal from a ray sensor into a voltage signal. CONSTITUTION:An ray sensor 1 outputs pulse current (i) by means of incidence of rays. Output current (i) is converted into a pulse voltage signal (v) by the use of a current-voltage converter 2. That is to say, the current-volage converter 2 is equipped with a junction field-effect transistor (a) son the input stage thereof, and the output power (i) from the ray sensor 1 is supplied in a gate. Further, the source of a junction field-effect transistor 2a is earthed, and drain is connected to the input of an amplifier 2b. And 2c represents feedback resistance and 2d indicates a capacitor for current integral. Next, the voltage signal (v) is amplified by the use of an amplifier 3 and introduced in a counter and the like as a detecting signal. Therefore, the input capacity can considerably be reduced, and the sensitivity of the detector can be improved.

Title: Ship propelling and steering device
Inventor: SAWADA MASASHI
IPC: B63H25/42
Filed: 1983-10-11
Abstract: PURPOSE:To simplify propelling and steering devices on a stern by providing a propeller for steering, which can idly rotate in the adverse direction, at the back of a propeller for thrusting, and making the rotary shaft of said steering propeller swingable in its horizontal plane. CONSTITUTION:Propulsive force on navigating is obtained by a thrusting propeller 2 and bevel gears 11, 12 are normally in a separated condition, allowing a steering propeller 3 to idly rotate in the reverse direction. When steering is carried out, the rotary shaft of the steering propeller 3 is swung horizontally by means of a steering mechanism, through a tailer 6, causing the back stream of the thrusting propeller 2 to be changed into a right or left propulsive force, to make a hull 1 rotate. On the other hand, when the steering propeller 3 is actively reversed by means of a driving mechanism 7 by connecting the bevel gears 11, 12 while navigating, a function as a double-reverse propeller can be obtained. Also, when the hull 1 is to be separated from a quay wall using the steering propeller 3 as a thruster, the propeller 3 is driven, with its rotary shaft perpendicular to the longitudinal direction of the hull and the bevel gears 11, 12 connected.

Title: Three-dimensional image pickup device
Inventor: OSHIMA MITSUO
IPC: G06T7/00
Filed: 1992-07-16
Abstract: PURPOSE:To secure the relative position accuracy of a photo-sensitive surface and reduce the burden on a corresponding point searching device by integrating two photo-sensitive surfaces, whose picture elements are arranged two- dimensionally, on one semiconductor chip. CONSTITUTION:In a package 20, a solid image pickup element 30 is die-bonded (fixed), where the first and second photo-sensitive surfaces 31, 32 are integrated on one semiconductor chip. One image forming device 51 has an optical axis H1 and builds an image on the first sensitive surface 31, while another image forming device 52 has an optical axis H2 and builds an image on the second sensitive surface 32. On these surfaces 31, 32, a number of sensitive elements 31a, 32a for photoelectric conversion are arranged two-dimensionally. The light from an object to be photographed passes through the optical axes H1, H2 and reaches the surfaces 31, 32. As these are integrated within the same semiconductor chip, their relative position accuracy depends directly upon the manufacturing accuracy of the semiconductor integrated circuit, being the order of magnitude of ums or below. Therefore, difficulty for adjusting the relative positions of the surfaces 31, 32 with each other is eliminated.

Title: Device for progressive encoding and decoding of multilevel image by stepped precision
Inventor: NAKAMURA HIROBUMI
IPC: H04N19/85
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To prevent a boundary line between blocks from being made visible by successively narrowing lattice intervals presumed on an image, generating lattice point-shaped pixel positions with intervals for each lattice interval, and referring to the whole closest encoded picture elements which are present with equal distances in the surrounding specific directions of the picture elements. SOLUTION: The surrounding specific directions of picture elements are defined as four directions. An image to be encoded storing mechanism 4 stores an image 2 to be encoded, and an encoding level counting mechanism 5 counts encoding levels from the preliminarily decided maximum value to a minimum value 1 in the descending order. A pixel instructing mechanism 6 generates the set of the positions of vertical and horizontal second-dimensional directions of the encoded picture elements in the encoding level instructed by the encoding level counting mechanism 5. A predictive encoding mechanism 7 operates the predictive encoding of the picture elements whose encoding levels are instructed from the maximum value to the minimum value 1 by the pixel instructing mechanism 6, and outputs encoded image data 3.  A control mechanism 9 controls the whole multilevel image encoding device 1 including the middle end of the encoding based on an encoding stop signal 8 from the outside part of the encoding device.

Title: Image pickup method in scanning type microscope
Inventor: HAKAMATA KAZUO
IPC: G02B21/36
Filed: 1990-07-18
Abstract: PURPOSE:To prevent an image from blurring by detecting illumination light passing specific positions inside assumed innermost main scanning ends and starting sampling operation on every scan once the passage is detected. CONSTITUTION:Two reflected patterns 61a and 61b at the positions B1 and B2 inside the assumed innermost scanning ends A1' and A2' of laser light 58 are slit and the parts are made low in reflection factor, so that the output S4 of a photodetector 62 varies periodically. This signal S4 is inputted to a sampling clock generating circuit 35 to generate a sampling clock S3, which is inputted to an A/D converter 51 to prescribe the sampling period of an analog image signal. A wave-shaped signal S9 is generated with the signal S4 and one pulse rises every time the positions B1 and B2 are passed. Then the image signal begins to be sampled when the pulse is inputted, and consequently even if a scanning end varies, the image signal begins to be sampled without fail when the positions B1 and B2 are passed, so the image having no blur is obtained.

IPC: G06T7/00
Filed: 1992-07-17
Abstract: PURPOSE: To provide a collation method which distinguishes forged signatures from a true signature and is dependent upon dynamic signature characteristics. CONSTITUTION: A reference set of true signatures is obtained in an initial phase C10. Numerical calculation of a set of dynamic characteristics 140.1, 140.2, and 140.3 of a reference signature is performed. The most characteristic partial set of these characteristics is selected and is statistically analyzed to obtain a set of parameters for signature collation. A member's signature is accepted or rejected based on coincidence with parameters (160 and 170). A collation method in a higher level can be applied to the accepted signature. A means 050 which accepts the signature by the collation method in a higher level is energized to allow the member to access a system.

Title: Focus detector
Inventor: KODAMA SHINICHI
IPC: G02B7/28
Filed: 1989-07-20
Abstract: PURPOSE:To detect a focal point independently of a pattern of an object by extracting only a video signal of a picture element having an angle with respect to a vertical and a horizontal direction from video signals as a focal point detection signal. CONSTITUTION:An object image formed onto an image pickup element 2 by an image forming optical system 1 is photoelectric-converted into a video signal. Then only a signal obtained from a picture element of a direction having an angle with respect to a vertical and a horizontal direction is used as a focal point detection signal and a signal obtained from other picture elements is used as an output video signal at the detection of a focal point thereby branching the video signal outputted from the image pickup element 2 respectively. The focal point detection signal is sent to a focal point detection block 3, from which a focal point evaluation signal is outputted to a control block 6. Since a picture element having an angle with respect to a vertical and a horizontal direction is used as the focal point detection signal in this way, the focal point is detected independently of the pattern of the object.
