Patent JP-H03113767-A (JP)
Title: Fast forward/rewinding device
Inventor: NAGAFUNE YUKIO
IPC: G11B15/46
Filed: 1989-09-25
Abstract: PURPOSE:To speedily transport a tape from the beginning to the end of the tape at a high speed by controlling a tape speed for its fast forward/rewinding modes to be constant based on a supply side reel rotation signal at the fast forward time and a take-up side reel rotation signal at the rewinding time. CONSTITUTION:In the fast forward mode, a rotation direction selector SW 26 is switched on to the side of a supply side reel rotation detector 22 to detect the supply side reel rotation signal of a square wave. This detecting signal is differentiated by C2 and R8, and moreover peak-detected by D1, R9, C3 and R10. When a period of the reel rotation signal is shortened, a peak-detected DC voltage is raised to turn on Tr2, and an input voltage to be inputted to a capstan motor drive amplifier 12 is restricted by R11. At the fast forward/ rewinding time, SW1 is on by a command switch 13 to control a motor drive voltage not to make the reel rotate more than a fixed speed, thus transporting the tape at a constant speed on the whole. The same operation is performed in the rewinding mode.

Title: Diffraction grating
Inventor: MURAKAMI TAKASHI
IPC: H01S5/12
Filed: 1987-10-01
Abstract: PURPOSE:To realize a diffraction grating which has a flat surface applicable to a semiconductor laser by providing the sections exposed with plural layers of different refractive indices formed periodically on a substrate as a surface. CONSTITUTION:The sections of the layers 2, 3 grown to multiple layers by alternately growing the crystals of AlxGa1-xAs layers 2 and AlyGa1-yAs layers 3 on the flat GaAs substrate 1, then subjecting the layers to diagonal polishing are exposed on the surface. Part of incident light penetrates from the surface into the layers 2 and 3 when the incident light enters the diagonally polished surface in parallel therewith. Said light is, therefore, reflected near the part where the refractive index changes, i.e., the boundary faces of the layers 2 and the layers 3. Since the refractive index changes periodically, the Bragg reflections by which the phases of the reflected light are unified are generated and the diffracted light is obtd. This diffraction grating has the flat surface and, therefore, the thermal decomposition of the diffraction grating and the collapse of the rugged shape and the consequent annihilation of the diffraction grating are obviated even when exposed to a high temp.

Title: Thin wire detector
Inventor: WATANABE SATOSHI
IPC: G01B11/08
Filed: 1996-08-15
Abstract: PROBLEM TO BE SOLVED: To enable the detection of the presence or absence of a thin wire stably for a long time by detecting the change of light reception signals at the time when light beam intersects the thin wire with vibrating, etc., a light projecting element and a light receiving element so that the optical axis may pass the thin wire. SOLUTION: A light projecting element 1 such as a LED and a light receiving element 2 such as a photodiode are fixed to a light projecting and receiving element holder 9 in positions facing each other. The holder 9 forms a moving body together with a plate spring 3 to which a permanent magnet 4 is fixed. The permanent magnet 4 forms a magnetic circuit together with an electromagnet 5. Adding an AC current of the frequency of the natural frequency of the moving body to the electromagnet 5 vibrates the moving body, and the optical axis 8 formed of the elements 1 and 2 intersects a thin wire, which is an object to be detected, as vibrating. At this time, the quantity of received light changes. By processing this change by a differentiating circuit to obtain a signal of a preferable S/N ratio, and it is possible to detect the presence or absence of the thin wire.  By fixing the light projecting and receiving elements on a substrate to vibrate slits to arrange light beam to intersect the thin wire, a similar effect is obtained.

Title: Horizontal scroll system
Inventor: KOJIMA KAZUHIKO
IPC: G06F3/048
Filed: 1991-09-27
Abstract: PURPOSE:To perform the smooth, fast and horizontal scroll even on a graphic screen to take time for the displaying of a character. CONSTITUTION:When the instruction of a horizontal scroll to a graphic screen 1 to display a part of the content of a table 2 is received from an operator, a scroll processing part 3 performs the horizontal scroll in the right or left, and displays it at the graphic screen 1. An edge character erasing processing part 4, when it finds out that the half of the character exists in the right edge or the left edge, erases it. An edge character displaying processing part 5 displays the character found out by the horizontal scroll. An original edge character re-displaying processing part 6 displays the character not displayed before the horizontal scroll because of the fact that the character becomes half.

Title: Contour correction circuit for image
Inventor: KANEMASA ISAO
IPC: H04N5/208
Filed: 1991-09-27
Abstract: PURPOSE: To make distinctive a luminance signal with a low transition level and to prevent the loss of fine transition levels by making a correction quantity for an outline signal separated from an image signal large, when its level is small and small, when large. CONSTITUTION: A 1st delay unit 201 delays an inputted luminance signal by one line and inputs it to 2nd and 3rd delay units 202 and 211 and a differentiator 203. The signal is further delayed by one line through the delay unit 202 and supplied to the differentiator 203, which adds it to the luminance signal from a 1st input terminal 200 and the delay unit 202, and further subtracts the one-line delayed luminance signal from the delay unit 201 to send out a vertical outline signal. The outline signal is generated at the level transition part of the luminance signal and corresponds to the level of the level transition of the luminance signal. Further, the delay signal from the delay unit 201 is passed through the differentiator 203, an outline correction part 213, and a 2nd adder 212 to generate an outline-corrected luminance signal, which is sent out of an output terminal 217.  Consequently, the sharpness of a screen represented with the luminance signal corrected with the transition level can be improved.

Abstract: PURPOSE:To increase the displacement of a scroll under the condition of being regulated by forming an involute base circle into an ellipse or flat oval, in a scroll compressor in which respective involute laps of both driving and driven scrolls are engaged with each other. CONSTITUTION:In this scroll compressor, both driving and driven scrolls are opposed with each other, and respective involute laps 1 erected in both these end plates are engaged with each other. In this case, each involute base circle 2 of the involute laps 1 is set to be an ellipse or flat oval. In brief, the involute base circle 2 is set to lee, for example, the ellipse made up of defining the side of a major axis (a) as 'r+alpha' and the side of a minor axis (b) as 'r', respectively. In addition, the whole involute lap 1 is set up in a maximum outer radial circle 5, while an outermost tip 4 is set up in a position serving as the side of the minor axis (b), and then this outermost tip 4 is reached to the maximum outer radial ciecle 5. Therefore an involute pitch in a direction of the major axis (a) increases as far as a portion of alpha, so that an amount of displacement is increasable as far as this portion alpha.

Title: Switching system for diversity reception
Inventor: KAMIKAWA YUTAKA
IPC: H04B7/26
Filed: 1994-09-20
Abstract: PURPOSE: To provide a diversity reception switching system which simplifies the circuit constitution and doesn't repeat unnecessary switching operations by detecting the demodulated signal level by, using only the output of the antenna selected at present. CONSTITUTION: When a demodulated signal is not detected from an antenna 1a or 1b selected at present within a prescribed time, a control circuit 15 switches it to another antenna 1b or 1a. If a maximum output level is lower than a preliminarily determined reference value and is lower than the preceding detected maximum output level at the time of detecting the demodulated signal, the antenna 1a or 1b is switched. Thus, the demodulated signal level is compared with the reference value, and the antenna is not switched if the level is higher than the level measured in the preceding control step though being lower than the reference level, and therefore, diversity reception switching is possible with the reception circuit of one system. Consequently, the circuit constitution is simplified, and the antenna is switched only when switching is necessary.
