Title: Original size detector for copying machine
Inventor: SUGANO HISAO
IPC: G03B27/62
Filed: 1985-11-26
Abstract: PURPOSE:To minimize the influence of the opening/closing operation of an original cover and to detect original size accurately by arranging an original size detector without crossing the surface of the original cover at right angles regardless of the state of the original cover surface when the original cover is held on one side end on a copying machine. CONSTITUTION:The original size detector 4 is provided under original platen glass 2 so that light emitted by a light emitting element 7 passes through a mirror 8 and a lens 5b and is converged on the top surface of the original platen glass 2 and reflected light from an original surface passes through a lens 5a and the mirror 8 and forms an image on a photodetecting element 6. The plane containing the optical axis between the light emitting element and lens and the optical axis between the photodetecting element and lens is not perpendicular to the glass surface and the light which is emitted by the light emitting element and then reflected irregularly by the original surface is photodetected by the photodetecting element to judge whether or not there is the original. Therefore, the original cover 3 never crosses the plane containing the optical axes between the light emitting element and lens, and the photodetecting element and lens throughout the opening/closing operation.

Title: Hearing aid with musical interval adjusting function
Inventor: ARAI YASUHIKO
IPC: H04R25/00
Filed: 1998-09-21
Abstract: PROBLEM TO BE SOLVED: To reduce a sense of displeasure and to allow the user to easily hear sound by applying A/D conversion to an acoustic signal picked up by a microphone without the use of a signal model and by applying interpolation processing to the converted signal so as to increase the number of sampled signals thereby converting a frequency spectrum and restoring a time length to an original length. SOLUTION: A musical interval conversion rate adjustment means 41 acts so as to output a musical interval conversion coefficient C to an acoustic signal interpolation means 21 and a time length correction means 31. The acoustic signal interpolation means 21 uses a method such as linear interpolation, quadratic curve interpolation or spline interpolation to interpolate a value between sampled signals so as to re-sample signals at a sampling frequency of fs/C (Hz). On the other hand, the time length correction means 31 acts like restoring only a time length of a discrete acoustic signal to an original length without changing a musical interval by using, e.g. the PICOLA method or the like. Since the musical interval of the received acoustic signal is adjusted to a musical interval offering the easiest hearing, articulation of words can remarkably be enhanced.
