Title: Video reproducing device
Inventor: KAWAMOTO HIROSHI
IPC: H04N9/83
Filed: 1988-01-20
Abstract: PURPOSE:To reproduce an image with a high grade by means of a comparatively simple constitution by using a luminance signal and a carrier signal obtained from the reproducing signal of a video head, and directly generating the primary color signal of RGB. CONSTITUTION:A reproducing signal Y+C of a video head 1 is converting- processing to the RGB primary color signal necessary for a color image reproduction. At such a time, the converting processing is immediately executed from a luminance signal demodulated from the reproducing signal Y+C of the video head 1 and a low band carrier chrominance signal C extracted from the reproducing signal Y+C of the video head 1, without going through the processing stages of a frequency conversion, a mixing, a color separation, and a burst detection. Thus, the processing operation frequency of the signal can be widely omitted, and the simplification of the constitution and the picture quality improvement of a reproduced image can be attained.

Title: Magnetic head
Inventor: OGAWA TAKAHIRO
IPC: G11B5/245
Filed: 1984-01-20
Abstract: PURPOSE:To improve the recording and reproducing characteristic at a low temperature by forming a gap spacer with a superconductor. CONSTITUTION:The gap spacer 5 is formed by using the superconductor between head halves 2 and 3 and thin film 51 made of superconductor is applies also to a wall face 41 of the tape side of a winding slot 4. When the superconductor constituting the gap spacer 5 reaches the state below the critical temperature and critical magnetic field, the electric resistance goes to 0, a permanent current is produced and the conductor becomes a perfect antimagnetic substance. Thus, no magnetic flux invades into the superconductor at all. The leaked magnetic flux near the gap is leaked to the tape, a strong magnetic flux density is produced and the recording efficiency is improved. Since the spacer 5 does not pass the magnetic flux when magnetic flux 7 is generated from the tape 6 at reproduction, the opposite side to the running face of the head 1, that is, the back core part receives the magnetic flux 7 so as to improve the reproducing efficiency.

Title: Method of fitting parts to ligneous board by ultrasonic wave
Inventor: TAKASUGI NORIHIRO
IPC: B29C65/00
Filed: 1987-01-19
Abstract: PURPOSE:To prevent a ligneous board from burning, by a method wherein a ultrasonic vibration is given to the ligneous board from the opposite side of the same by abutting fitting parts against the same. CONSTITUTION:Fitting parts 4 are mounted on a holding jig 7 by turning a protrusion 3 upward and then a ligneous board 5 is mounted on each of the fitting parts 4.... Then after a ultrasonic horn 2 is abutted against the ligneous board 5 by descending the same by actuating an air pressure cylinder 8, ultrasonic vibration is given by the ultrasonic horn 2. Burning does not happen as the ultrasonic vibration is transmitted to the circumference of the surface of the ligneous board 5 at the opposite position of the fitting part, and heat energy does not concentrate so as to burn the woody parts of the ligneous board 5. With this construction, each of the protrusion 3... turns fittable into the ligneous board 5 and the fitting parts 4 is welded to the ligneous board 5.

IPC: F01K7/44
Filed: 1991-01-30
Abstract: PURPOSE:To provide a steam turbine system capable of storing all the heat of surplus steam by supplying the surplus steam extracted from a boiler separately to a high pressure deaerator and a low pressure deaerator and controlling the amount of the extracted steam. CONSTITUTION:Steam is extracted from a steam turbine 2, controlled with a high pressure control valve 10, and supplied to a high pressure deaerator 11 to heat and deaerate water fed from a feed water tank 15 through a high pressure feed water line 18.

Title: Recording medium used for conduction transfer method
Inventor: KAWANISHI TOSHIYUKI
IPC: B41M5/26
Filed: 1988-01-21
Abstract: PURPOSE:To prevent scumming without degrading a transfer image by providing a scumming-preventive layer on a porous polymer gel containing an ink. CONSTITUTION:An ink-containing polymer gel layer 2 is provided on a conductive substrate 1, and thereon a scumming-preventive layer 9 is provided. The scumming-preventive layer is a thin layer of an organic or inorganic material capable of an electric conduction or a layer dispersing fine particles of an organic or inorganic material therein. If the polymer gel is an anion polymer gel, the application of a positive voltage to a recording electrode and a negative voltage to a return electrode causes the polymer gel to shrink toward the positive side, thus making the incorporated ink bleed on the side of a recording medium (paper). Therefore, when a recording signal 4 is applied to a title recording medium through the recording electrode 3, the ink of the appropriate part oozes out on the surface, and the oozed out ink is transferred to the paper (material to be recorded) pressurized by a pressure roller 6.

IPC: G01F15/00
Filed: 1995-01-25
Abstract: PURPOSE: To achieve a higher accuracy simply and at a lower cost by arranging a rectifier grating comprising a mesh or a honeycomb at a sub-path inlet to match the inner diameter of a sub-path. CONSTITUTION: A sub-path 1 is molded by metal, a synthetic resin or the like. A rectifier grating 2 set at an inlet part of the sub-path 1 is made up of a mesh comprising the metal and the synthetic fiber. An exothermic resistor 3 and a thermosensitive resistor 4 are set in the sub-path 1 behind the rectifier grating 2. Then, an applied current is supplied by a drive circuit 8 to heat the exothermic resistor 3 at a fixed temperature. The heating temperature is corrected by the thermosensitive resistor 4 to always keep a difference constant between the temperatures of sucked air detected in the exothermic resistor 3 and that in the thermosensitive resistor 4 regardless of the amount of the sucked air.  Therefore, a feedback control is performed by the drive circuit 8 to always keep the temperature difference between the exothermic resistor 3 and the thermosensitive resistor 4 constant by supplying a high current when a high current flows in a main air path and a low current when a low current flows.

Title: Developing method
Inventor: YOSHIDA MINORU
IPC: G03G9/08
Filed: 1988-01-21
Abstract: PURPOSE:To improve the reproducibility of narrow lines by including particles subjected to treatment for conduction in a developer and allowing the edge effect to produce proper results. CONSTITUTION:The developer consists of at least two kinds of toner, and toner having <=10<10>OMEGA.cm resistivity and toner having >=10<10>OMEGA.cm resistivity are mixed to obtain this developer. When this developer is used and a bias including an AC is applied between a photosensitive body and a developing device to develop an image, the electric field in boundary parts is strengthened because lines of electric force are concentrated to conductive toner, and the edge effect produces proper results because insulating toner is moved along these lines of electric force. Thus, the reproducibility of narrow lines is improved.
