Title: Convergence measuring device
Inventor: UNO SHINICHI
IPC: H04N17/04
Filed: 1988-03-23
Abstract: PURPOSE:To enable high-precision convergence information to be obtained by getting the weight center of measurement pattern dots based on processed picture image data and, calculating the convergence information relative to this weight center. CONSTITUTION:When a measurement pattern displayed on the display surface of a color picture tube 10 with a pattern generating means 11 is imaged with an imaging unit 14, a picture image processing means 19 continues expansion processing on this picture image data until each gap between phosphor agents within one dot of the measurement pattern is vanished, to execute contraction processing on the picture image data which is undergone expansion processing. Based on this picture image data which is undergone the image processing, a convergence operating means 22 obtains the weight center of one dot of the measurement pattern and, calculates convergence information relative to this weight center. With this, regardless of the way a phosphor agent is scattered, the device can obtain the weight center accurately to work out the high- precision convergence information.

Title: Elimination of residual magnetism of electromagnet
Inventor: NIWA HIDEO
IPC: H01F13/00
Filed: 1989-03-20
Abstract: PURPOSE:To realize the highly reliable releasing of an object to be attracted by detecting the magnetic flux density of a core with a magnetic sensor, and interrupting the current supply to a reverse exciting coil when residual magnetism vanishes. CONSTITUTION:When a contact 11 is opened, contacts 13a, 13b are opened, and contacts 14a, 14b are closed. Thus a current circuit to an inverse exciting coil 4 is formed, and inclined to make a current flow in the direction inverse to an arrow A. However, on account of the inverse electromotive force of a coil 4, a current in the arrow A direction flows in the closed circuit constituted of the coil 4 and a varistor 18 for a short period. When the current attenuates and becomes zero, an inverse exciting current, which is restricted lower than an ordinary value by a limiting resistor 15, begins to flow in the arrow B direction, and inverse exciting magnetic flux is applied to a core 2, so that the residual magnetism is gradually cancelled. When the residual magnetism becomes zero, this state is detected by a magnetic sensor 5 installed in the magnetic path of the core 2, and an operation coil Fx turns to the non-operation state. Hence a contact Fxa is opened, so that the contact 14a, 14b are opened, and the current flowing for reverse excitation is ended. As a result, the magnetic flux in the iron core 2 vanishes, and a work 25 is rapidly released, so that the reliability of releasing can also be increased.

CONSTITUTION:A monochromatic light from a light-emitting element 1 is split into two beams by a light-wave-demultiplexing wave-synthesizing element 2 and is propagated as left/right-turning light within a sensor coil 6. The light is incorporated by the light-wave-demultiplexing wave-synthesizing element 2 and then reaches a light- receiving element 9 and then detects a strength of interference light. A DC component detection 10 stably controls the quantity of light of the light-emitting element 1. A fundamental wave is detected synchronously by a synchronization detection portion 17. A phase modulation element excitation control portion 15 has a basic clock and creates a sinusoidal wave of an input given to a phase modulation element 7. Synchronization signalsOMEGA and 2OMEGA (carrier signals) for synchronous detection are created at the synchronization detection portions 17 and 11. When an input Pa which gives an optimum phase is determined, a synchronization detection with a high sensitivity can be performed by fixing the value.
