Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To adjust and synthesize images without decoding re-compression by replacing a DC component of a sum of both outputs of an extract means for a DC component of a luminance signal in a received compression video signal V and a setup level setting means with a DC component of the luminance signal of the signal V. SOLUTION: One of compressed video signals V received from an input terminal 101 is given to a Y-DC extract device 102 and an A/D converter 104 converts the voltage set by a variable resistor 104 into a digital value to set a correction amount. An adder 105 adds a DC component of a luminance signal outputted from an extract device 102 and a correction amount of a setup level outputted from the A/D converter 104 and outputs a DC component of the corrected luminance signal. A multiplexer 106 being a signal replacement means receives the other signal V and replaces the DC component of the luminance signal with the output signal of the adder 105 and provides an output. Thus, the video image is edited at a low cost without deterioration in image quality without conducting decoding and compression.

Filed: 1993-02-12
Abstract: PURPOSE:To provide an apparatus for producing float glass capable of performing the operation for a long period even if the glass is high-strain point glass or a low-expansion glass by constructing hangers from Si3N4 or SiC. CONSTITUTION:This apparatus for producing beltlike glass (G) is obtained by forming a ceiling part of a molten metallic bath vessel 2 for housing a molten metallic bath l from a refractory 3 engaged with hangers 5 and continuously feeding molten glass to the bath surface of the molten metallic bath 1. In this apparatus, the hangers 5 are constructed from Si3N4 or SiC. In conventional apparatuses of this type, the hangers 5 have hitherto been constructed from austenitic nickel-chromium steel. Although uses of high-strain point glass and low-expansion glass have recently been enlarged, these glasses usually have a high viscosity and the temperature within the forming region need to be raised. The Si3N4 or SiC is extremely stable at high temperatures. The apparatus for producing the float glass operable for a long period even if the glass is high-strain point glass or low-expansion glass car be provided by constructing the hangers therefrom.

Title: Stabilizer detection apparatus
Inventor: OTSUKA JUN
IPC: G11B19/10
Filed: 1994-02-22
Abstract: PURPOSE:To prevent a disk from being turned at high speed in a state that a stabilizer does not exist by a method wherein, when the rotation of the disk is started, a servo waveform is detected, an angular velocity is computed and the existence of the stabilizer is detected. CONSTITUTION:A Hall motor 1 is coupled to a turntable, and it is turned and driven by a Hall-motor drive circuit 2. The waveform of the rise of a starting current for the circuit 2 differs according to whether a stabilizer is placed on an optical disk or not. Consequently, the waveform of the starting current is shaped to a pulse waveform by a waveform shaping circuit 3 provided with a comparator, and the existence of the stabilizer is detected by a microcomputer 4. Thereby, the nonexistence of the stabilizer can be detected in a short time of nearly one rotation, and it is possible to prevent an accident that the optical disk is detached from the turntable when it is turned at high speed.

Title: Magnetic field center measuring instrument
Inventor: KUMAGAI KEIKO
IPC: H05H7/00
Filed: 1989-02-28
Abstract: PURPOSE:To take an accurate measurement without trouble by arranging the magnetic center measuring instrument for a four-pole electromagnet in a magnetic field space surrounded with four magnetic poles and measuring the position of a measuring element optically. CONSTITUTION:This measuring instrument 2 is constituted by joining a float 7 with a superconductive body 1 and dipping the measuring element 15 which is heavy enough to become stationary at an optional position in a cooling medium 10 put in a heat- insulated container 16 in the cooling medium 10. The gravitational force operating on this body 1 is canceled by the buoyancy of the float 7 and the body 1 is freely movable in the cooling medium 10 without being affected by the gravitational force. Further, the body 1 when cooled below transition temperature where superconductivity is obtained becomes diamagnetic to remove magnetic flux from a material. Here, the body 1 moves in the cooling medium 10 and becomes stationary where the energy for removing the magnetic flux is least. This position is the center of the magnetic field of a magnetic space where the magnetic field in the magnetic field space surrounded with the four magnetic poles while the magnetic device is arranged in the space becomes zero and this position is measured by an optical means to find the magnetic field center directly.

Title: Stabilization of chloroprene
Inventor: TAKEDA TERUO
IPC: C07C21/21
Filed: 1979-04-19
Abstract: PURPOSE: To prevent the generation of α-and ω-polymer of chloroprene over a wide temperature range for a long time, and to make possible the following polymerization reaction without removing the stabilizer, by the use of a specific amount of a copper-containing material as a stabilizer.  
     CONSTITUTION: The α- and ω-polymerization of a chloroprene monomer is suppressed for a long time over a wide temperature range from a low temperature to a high temperature, by conacting the monomer with a material containing at least 0.1ppm (as copper based on the monomer) of copper, e.g. metallic copper, copper alloy, copper salts of inorganic or organic compounds, copper chelate compounds, copper mercaptides, etc. Since the amount of copper is very small, it is not necessary to remove the stabilizer before polymerization process, which is inevitable procedure in the conventional stabilizing process. Moreover, copper has an accelerating effect to the redox-type reaction.
