Title: Method for inspecting parts in automatic parts feeding system
Inventor: MORI HIROKAZU
IPC: H04B7/26
Filed: 1983-02-28
Abstract: PURPOSE:To make possible the detection of defects in parts with ease and the simplification as well as miniaturization of the construction of an apparatus by inspecting the parts to be inspected without allowing them to stop moving through at least more than one optical fiber sensor while causing a reflective optical fiber sensor head to conduct reciprocation at high speed. CONSTITUTION:A sensor head 3 equipped with reflective optical fiber sensors 4, 4' is arranged opposite to a route where a part 1 flows and caused to conduct reciprocation at high speed by a mechanical transfer means in both the lefthand and righthand directions X, X' relative to the direction in which the part 1 flows as shown by an arrow Y and radiate light to the part 1 running on a rail 5. For instance, one sensor 4 is made to inspect whether a defect is present on the surface of the part 1, the other 4' being made to inspect whether a pinhole is present. The light emitted from a projector will be reflected at a proper level and received by a light receiver if the shape of the part 1 is not defective. In case there exists a pin brake 2a or a flaw 1a, the level at this spot differs and accordingly the presense of a defective shape of the parts 1 is readily identified by detecting the spot.

Title: Fm multiplex receiver
Inventor: KURODA TORU
IPC: H04B14/04
Filed: 1988-02-17
Abstract: PURPOSE:To reduce the effect of an error in the listening sense by receiving a broadcast ADPCM sound signal, utilizing the error detection capability of a (272, 190) code and applying interpolation while suppressing the increase in the absolute value of an ADPCM data in an FM multiplex broadcast using a higher frequency region than 53kHz of, e.g., an FM composite signal. CONSTITUTION:An FM multiplex signal received by an antenna is converted into a multiplex signal by a tuner section 201, then the multiplex signal is subject to QPSK demodulation in a QPSK demodulation section 202 and inputted to a RAM 203. A CPU 204 extracts data from the RAM 203 to apply error correction by a (272, 190) decoder 205. A CPU 204 extracts data from the RAM 203 and a (272, 190) decoder 205 applies error correction. In this case, interpolation is applied to the data after decoding and the resulting data is transferred to an ADPCM decoder 206. In this interpolation method, the interpolated value is made zero to reduce the change in the absolute value and the sample having an error is muted. If there is an error as a result, since the absolute value is not monotonously increased after the ADPCM decoding, the possibility of deteriorating the quality due to large mixed noise in a reproduced sound is precluded.

Title: Color cathode-ray tube
Inventor: TANAKA KASUMI
IPC: H01J9/227
Filed: 1990-02-13
Abstract: PURPOSE:To prevent a color drift on a display screen caused by the external magnetic field by forming phosphor dots formed at corner sections of the display screen into an ecliptic shape so that the long diameter is faced to the diagonal axis direction of the display screen. CONSTITUTION:Electron beams 2 are formed into a circular shape at corner sections of the display screen 3 of a color cathode-ray tube, and elliptic phosphor dots 1 are formed into an elliptic shape with the long diameter faced nearly to the diagonal axis direction of the display screen 3 of the color cathode-ray tube. When an electron beam is emitted from an electron gun, the electron beam is affected by the external magnetic field, its orbit is bent, and its landing position is displaced in the perpendicular direction to the diagonal axis of the display screen 3. The other color margin distance in the perpendicular direction to the diagonal axis is extended by the amount that the diameter (short diameter) of the elliptic phosphor dot is shortened in the perpendicular direction to the diagonal axis. The electron beam 2 is rarely miss-landed on the adjacent phosphor dot 1 in the perpendicular direction to the diagonal axis if the external magnetic field is about the normal magnetic field when the electron beam 2 is affected by the external magnetic field.

Abstract: PROBLEM TO BE SOLVED: To perform the input of data to an image processing means and the input/output of data to a system bus in parallel to each other by cutting the connection between the system bus and a buffer storage means via a separation means. SOLUTION: The local buses A23 and B21 can be separated from each other by a gate circuit 22 for a compression device 7 in an image processing mode. Thus, a control part 28 sends a signal to a bus bridge 20 in a write cycle (1) set to a RAM buffer 24 and the data are successively outputted to a local bus B from a buffer included in the bridge 20 synchronously with a clock signal. Then the part 28 sets the circuit 22 in a conductive state and outputs the data of the bus B to a local bus A. In a read cycle (2) and a DMA write cycle (4) of the buffer 24, the part 28 sets the circuit 22 in a non-conductive state and separates the buses A and B from each other. Thereby, both operations (2) and (4) can be simultaneously carried out.
