Title: Detecting apparatus of position of object using optical fiber
Inventor: INOUE KAORU
IPC: G01B11/00
Filed: 1987-04-20
Abstract: PURPOSE:To make it possible to secure a wide detection area by constructing a plurality of optical fibers on the photodetector side so that they have different directivities from one another. CONSTITUTION:An optical fiber sensor 1 is provided at least with one light- emitting element and a plurality of photodetectors having different directivities from one another. Data on the quantity of light at a prescribed reference position of an object measured by the optical fiber sensor 1 are stored in RAM. A digital signal processor 11 receives as an input the data on the quantity of light of the optical fiber sensor 1 at arbitrary positions of the object to be measured except for the reference position, compares said input data with the data of the reference position read out of RAM and detects the position of the object from the quantity of deviation obtained through comparison.

Title: Signal processing circuit
Inventor: EDO YASUHIRO
IPC: H03K5/04
Filed: 1989-04-17
Abstract: PURPOSE:To obtain a stable pulse width by prolonging the time of a one-shot signal with a delay circuit, and preventing an input signal whose level is once increased from decreasing with a control circuit. CONSTITUTION:When an input signal changes from '0' to a level '1', since a level at a node 13 goes also to '1' a transistor(TR) 25 is cut off. Since TRs 25, 26 are cut off, a level at a node 12 connects to ground to assist the change from '1' to '0' thereby bringing the level rapidly to '0'. Since the TR 26 is not closed till the signal passing through the delay circuit and outputted reaches '0', the level of the node 13 remains '1'. When the node 14 reaches '0', the level of the node 12 goes to '1' and the level of the node 13 goes to '0'. Thus, even when the width of the input signal changes, the output pulse width is made constant.

Filed: 1985-05-10
Abstract: PURPOSE:To make possible the easy rotation of a bobbin and the consequent easy execution of winding by meshing an outside driving gear with a gear provided to the bobbin. CONSTITUTION:A core 8 consisting of ferrite which is a high permeability material consists of a back core 10 molded to a cylindrical shape and a gap part 9 which is simultaneously molded.

On end of a conductor for the coil is fixed thereto and the gear part 13 is meshed with the outside driving gear and is rotated to form a coil part 14. The core part of an erasing head is thus assembled. The number of the parts to be used is thereby decreased and the laborious assembling operation of the core and coil is made extremely easy. The inexpensive production of the erasing head is thus made possible.

Abstract: PURPOSE:To improve drivability by correcting the signal of a karman vortex type air flow sensor according to the number of engine revolution when the engine is in low-speed high-load operation state where Karman vortex is disturbed, thus improving the linkage between control zones. CONSTITUTION:In order to control fuel feed, the information supplied from an air flow sensor 1, engine revolution-number sensor 5, and a throttle opening sensor 4 for detecting the loaded state of the engine from the opening of a throttle valve 8 is read-in, and it is judged if the operation state of the engine E is within a prescribed karman vortex range or not. If the operation state is within the karman vortex rage, the correction coefficient in proportion to the erroneous operation of the air flow sensor 1 is multiplied with the fuel injection pulse time, and the second pulse control signal thus obtained is supplied into a fuel injection valve 2 from a computer 3, having preference to the first pulse control signal, and thus karman synchronous fuel injection is performed.

Abstract: PURPOSE:To enhance diagnostic accuracy, to reduce the operation load of an operator and to prevent an examinee from receiving an unpleasant feeling, by mounting a detection means for detecting the angle of rotation of a top plate and a control means for controlling the number of rotations of a top plate driving motor corresponding to a detection signal. CONSTITUTION:When a top plate 7 is rotated, the angle of rotation of a top plate driving motor 14 is detected by an angle detection circuit 11 and converted to a voltage signal by a voltage signal converter circuit 12 receiving the detection signal of said circuit 11 and the top plate driving motor 14 is controlled by a motor rotation control circuit 13 so that the number of rotations of said motor 14 are increased or decreased corresponding to the angle of rotation of the top plate 7. As a result, even when the top plate 7 is not rotated at constant angular velocity, the top plate 7 is always rotated at constant angular velocity. Therefore, the top plate 7 having an examinee 6 placed thereon can be stopped at a desired position and, therefore, diagnostic accuracy is enhanced and the operation load of an operator can be reduced and a diagnostic time can be reduced without giving an unpleasant feeling to the examinee 6.

Abstract: PURPOSE:To accurately and smoothly attain the track jump by applying operation processing to a track jump drive signal while adding the displacement of a recording/reproducing processed body by the restored elastic force of a midpoint support to a signal corresponding to a jump. CONSTITUTION:A track jump (TJ) trigger T and a TJ direction signal S are fed to a TJ pulse generating circuit 21 from the host side in a TJ circuit 20 and a signal S1 in response to the jump is sent to a differential amplifier 22. The amplifier 22 receives the signal S1 and the displacement signal S4 of an actuator ACT 11 from an AGC circuit 32 to apply the operation processing so as to exclude the effect of displacement of the ACT 11 in the track direction thereby outputting a TJ drive signal S2. The signal S2 is fed to an adder 33 via a switch 23, where the signal S2 is added by a track servo drive signal S3 excluding the effect of the restored elastic force from a track direction drive servo circuit 18 and the result is fed to a tracking coil 15. Thus, the coil 15 is operated and an objective lens 7 is track-jumped to a proper position.

Abstract: PURPOSE:To reduce the energy consumption by connecting an anti-parallel circuit of diodes in series to a first load and connecting light emitting diodes of anti-parallel connection, which constitute a photocoupler capable of emitting light in both directions, in parallel to said anti-parallel circuit. CONSTITUTION:When a first load 3 is made conductive, a voltage drop is generated between both ends of diodes of an anti-parallel connection circuit 15 by the current flowing to the load 3, and two light emitting diodes 16 of anti- parallel connection are caused to emit light alternately, and a photo transistor TR 9 constituting the photocoupler is turned on.

Further, an n type epitaxial layer 4 of the third layer is further grown on the layer 3. The resistivity of the layer 4 is similar to the epitaxial layer of the first layer. Then, in order that an oxidized film 5 is formed on the surface of the wafer and a p type emitter layer 6 is consecutively formed, boron ions are, for example, implanted through the film 5. Subsequently, a p type emitter layer 6 of approx. 1mum in depth is formed by annealing it in nitrogen. In this manner, an aluminum electrode 7 (4mum thick) is formed by vacuum deposition and photoetching technique on the silicon wafer in which the formation of a junction is finished, and the wafer is divided into 4mm.-square chips.
