IPC: H04N5/44
Filed: 1997-07-03
Abstract: PROBLEM TO BE SOLVED: To improve the detection accuracy of noise level components while including external noises and to cancel image distortion or noise sound caused by diversity operation by detecting the noise component of a pedestal in the equivalent pulse domain of a received video signal and comparatively detecting noise levels at two spots. SOLUTION: The pedestal noise at the first half section of the equivalent pulse domain after the vertical synchronizing signal of the received video signal is detected and the noise level held by a sample-and-hold(S/H) circuit 26 IS inputted to a comparator circuit 28. The pedestal noise in the latter half section is detected and inputted to the comparator circuit 28 while being lowered rather than the level held by an S/H circuit 17 by an attenuator 27. The comparator circuit 28 outputs 'L' when the level of the attenuator 27 is lower than the level of the S/H circuit 26. When the external noise is mixed, 'L' is outputted from the comparator circuit 28, a switch circuit 29 is opened and the output of a comparator circuit 28 erroneously operated by the external noise is inhibited by the switch circuit 29.

Title: Analysis device
Inventor: OGAWA KIYOSHI
IPC: G01N23/225
Filed: 1992-07-06
Abstract: PURPOSE:To prevent the appearance of gear backlash, and enable a rotary holder to continue rotation, regardless of a rotating direction, by providing a magnet on the rotational axis of the holder, arranging a plurality of electromagnets around the magnet and selecting the magnetic pole of each electromagnet via the control of current supplied thereto. CONSTITUTION:When a sample holder 1 is made to rotate on the operation of a motor 7, backlash appears due to the play of the engagement section of gears 3 and 6, and the mechanical structure of the motor 7. The magnetized state of each electromagnet is changed by controlling current supplied from a control section 8 to an electromagnet group. As a result, repellent and attracting forces are generated between electromagnets 5 and a magnet 4, and a clockwise rotating force is thereby generated. Thus, a force acts in a direction opposite to the rotating force of the axis 2 of the holder 1. Current supplied to the electromagnets 5 arranged around the magnet 4 is selected sequentially at every 45-degree rotation of the axis 2. According to this construction, a force opposite to the rotating direction of the axis 2 is continuously applied and, therefore, the backlash of the gears 3 and 6 can be prevented from occurring.

Abstract: PROBLEM TO BE SOLVED: To prevent the formation of the bridge of a material to be crushed supplied to the center part on a table by attaching a bridge collapsing member extending toward the required position above the center part of the table to the side surface part of a roller. SOLUTION: A rod-shaped bridge collapsing member 23 extending toward the required position above the center part of the table 4 is attached to the side surface part of a roller 7. At a time of the crushing of coal, the table 4 is horizontally rotated and the rod-shaped bridge collapsing member 23 extending toward the required position above the center side surface part of the roller 7 becomes a form performing relative revolving motion with respect to the table 4. Therefore, for example, even if the moisture of coal supplied from the part above the center part of the table 4 is much and the flowability thereof becomes inferior and a coal bridge is formed at the center part low in centrifugal force of the table 4, the coal bridge is collapsed by the bridge collapsing member 23 to be prevented from growth.

Title: Metallic gasket
Inventor: MATANO YASUHIRO
IPC: F16J15/08
Filed: 1989-07-11
Abstract: PURPOSE:To prevent the occurrence of leakage by a method wherein a tubular member in a C-shape in cross section formed such that a metallic sheet having a low thermal expansion coefficient is laminated to the inner side of an outer metallic sheet having a high thermal expansion coefficient is formed in an annular manner, and also when a piping temperature is decreased, the diameter of the C-shaped pipe is increased to close a gap between flange couplings. CONSTITUTION:A metallic sheet 2 having a low thermal expansion coefficient is laminated to the inner side of a metallic sheet 1 having a high thermal expansion coefficient to form a tubular member in a C-shape in cross section, which is formed in an O-ring annular body. This constitution decreases the outer diameter of the opening part of a metallic gasket forming an annular body since the outer metal 1 is expanded more widely than the inner metal 2 when the temperature of fluid in a piping is increased. Since the outer metal 1 is shrunk more widely than the inner metal 2 when the temperature of fluid in the piping is decreased, the opening is spread and the outer diameter of the metallic gasket is also increased. Thus, even when a distance between the flanges of the pipings is increased, no gap is produced between the metallic gasket and the flange, and a flange coupling is usable even for a piping system for high temperature high pressure superheat steam and the like.

Abstract: PURPOSE:To make the effect of the inclination of a disc hardly inflicted by providing only high frequency component for two-devided outputs from photoreceiving sensor and performing synchronous detection dividing the output difference by the output sum. CONSTITUTION:A signal processing circuit 7 consists of high pass filters 71 and 72 to receive outputs divided into two in the radiant direction of the optical disc 5 from the photoreceiving sensors 61 and 62, a first adder to add outputs from the high pass filters 71 and 72, a second adder for the substraction of the outputs, a synchronous detector 75 for the synchronous detection by the output from the second adder 75 with that from the first adder 74, and a low pass filter 76 to output the tracking error signal by receiving the output from the synchronous detector 75. With this structure, if the optical disc declines to provide 1% variation of quantity of light, only 1% variation is received because the tracking error signal is generated from a high frequency signal. This permits the tracking error detection which is hard to be affected by the inclination of the disc.

Title: Circuit for correcting tracking of antenna circuit
Inventor: OHASHI TAMAKI
IPC: H04B1/16
Filed: 1987-07-20
Abstract: PURPOSE:To correct the characteristic curve of a synthesized capacity to a channel selecting voltage to a linear state, by connecting a voltage changing circuit to one electrode of a varactor diode facing the other electrode, across which the channel selecting voltage is applied, so that the change of the synthesized capacity becomes smaller in an area where the channel selecting voltage is high. CONSTITUTION:A voltage changing circuit 7 is provided so that the anode potential of a varactor diode 6 in an auxiliary tuning circuit 4 can change in the increasing direction, namely, the potential difference across both sides of the diode 6 can become lower than an actually applied channel selecting voltage when the channel selecting voltage applied across the cathode of the varactor diode 6 changes in the increasing direction in an area where the channel selecting voltage is high. When the channel selecting voltage applied across the cathode of the diode 6 is represented by V1, the variable voltage of the voltage changing circuit 7 is applied across the anode of the diode 6 so that the voltage V1 can become another voltage V1' which is apparently lower than the voltage V1. Therefore, the characteristic A of the synthesized capacity can be corrected to a linear state in the area where the channel selecting voltage is high.
