Title: Photodetecting device
Inventor: NAKAMOTO HIROSHI
IPC: G02B6/42
Filed: 1988-01-18
Abstract: PURPOSE:To obtain the photodetecting device having a high optical coupling efficiency, and also, being miniature by providing a concave reflection mirror having a desired concave surface by inclining it against the photodetecting surface of a photodetector which has been placed on a circuit board, so as to be opposed to an emission end face of an optical fiber. CONSTITUTION:A light beam which has been emitted like a conical body using a horizontal axis as an axis from an emission end face of an optical fiber 10 is projected to a concave surface 21 of a concave reflection mirror 20, and reflected in the direction of a photodetector 1 thereby. In this case, the concave reflection mirror 20 has, for instance, a desired concave surface 21 such as a paraboloid of revolution, therefore, a reflected light is condensed to the photodetecting surface 3 of the photodetector 1. That is, since the reflected light is condensed to the photodetecting surface 3, even in case of a narrow and small photodetecting surface, the optical coupling degree of the optical fiber 10 and the photodetector 1 is high. Also, the optical fiber 10 can be installed adjacently in parallel to a circuit board 5, therefore, comparing with the case when the axis center of the optical fiber has been mounted vertically to the surface of the circuit board 5, the mounting work is facilitated, and also, the photodetecting device is miniaturized.

Abstract: PURPOSE:To make low-unit cost of production and miniaturization achievable by promoting the simplification of structure. CONSTITUTION:In this document conveyor, both surfaces of a feed roller 32 and an opposite roller 33, constituting a conveyor roller conveying a document to a document reading part 10 at a specified speed, are formed with the same characteristic material, and if this feed roller 32 is rotated and driven, the opposite roller 33 is made so as to be dragged into rotation together in terms of design. In addition, if one document gets into space between the feed roller 32 and the opposite roller 33, these rollers 32, 33 are dragged together, conveying the document as keeping it intact, and supposing double-feed of the document has occurred, the opposite roller 33 is not turned at all, so that only the lowermost document is conveyed by rotation of the feed roller 32.

Title: Information reproducer
Inventor: TANAKA SHINICHI
IPC: G11B20/10
Filed: 1984-01-19
Abstract: PURPOSE:To allow reading of information securely and stably from the reproducing signal whose duty ratio is changed by controlling a duty ratio digitally. CONSTITUTION:When a duty ratio of a reproducing signal is right, a shaped reproducing signal obtained by wave-shaping said signal comes to have the same waveform as that of an original digital signal (a), but when a duty ratio has deviated, pulse width changes as shown by a signal (c). If, for instance, it is assumed that positive pulse width has become wider, a digital signal (d) having the same waveform as that of the original digital signal (a) can be obtained by delaying a rising edge. Namely, a right digital signal can be reproduced even from the reproducing signal having a deviated duty ratio by controlling appropriately the difference of a delay time in accordance with the deviation of a duty ratio.

Title: Ultrasonic motor and electronic device therewith
Inventor: IINO AKIHIRO
IPC: H02N2/00
Filed: 1999-01-14
Abstract: PROBLEM TO BE SOLVED: To stabilize self-oscillation to enable generation of a large drive signal, by providing a polarizing portion for detection to detect a drive signal based on the excitation of the polarizing portion for drive to the position including the part which provides maximum distortion of vibration for exciting a piezoelectric vibration body. SOLUTION: The polarizing portion for detection 7c is in the symmetrical positional relation at the center of node of the flexure vibration wave when the first polarizing portions for drive 7a are vibrated to generate the flexure vibration wave in an elastic body 6. Since the polarizing portion 7c for detection deflects similar to the first polarizing portion 7a and also symmetrically deflects to a large extent for the center, a drive signal including large drive frequency component f0 is detected for unwanted frequency component. Namely, the drive signal includes much component of drive frequency f0 and also includes a less amount of unwanted frequency component to improve detection sensitivity of drive frequency f0.  Therefore, sufficient detecting area can be acquired without reducing the excitation area of the first polarizing portion 7a, thereby maintaining the driving force and obtaining a large drive signal.

Title: Focusing detector
Inventor: UTAGAWA TAKESHI
IPC: G03B13/36
Filed: 1986-01-20
Abstract: PURPOSE:To form a focus detector at high accuracy by varying a weight coefficient for multiplying an output corresponding to both ends of a picture element and that corresponding to central parts except said ends with respect to a difference between picture element outputs of a pair of photoelectric element arrays and a correlation quantity signal. CONSTITUTION:In case of a front pin, images on the photoelectric element arrays 5 and 6 move downward and upward, respectively. In case of a back pin, they moves upward and downward reversely. Where outputs from photoelectric elements p1-p4 and those from photoelectric elements p'1-p'4 are x1-x4 and x'1-x'4, respectively, a signal processing circuit 7 obtains correlations IN and ID from these photoelectric outputs. Provided that the IN is the mutual correlation functions, and the ID is auto-correlation function, that is, denotes the contrast of the image. When a standardized correlation function IO=IN/ID is obtained, a signal IO comes to zero without fail where a focus position alphais given. When the front pin gamma or the back pin beta is given, the IO comes to '1' without wail.
