CONSTITUTION:The magnetic field in a prescribed direction is generated in the spacing part 3 of the yoke core 2 when the coil 7 is energized. A magneto- optical effect is then generated in the magnetic fluid 5 and controls the light transmission characteristics, such as transmitted light quantity and transmitted light intensity and, therefore, the on-off of light are controlled by on-off controlling the energization and de-energization of the coil 7. In addition, medium gradation light can be transmitted by regulating the current of the coil 7. The response speed of the on-off actions is extremely faster than the on-off actions of the conventional electrooptical elements and a high contrast ration is assured. The correct resolution of the medium gradation, etc., is obtd. when this element is applied to a display, etc. Further, the material st of the fluid 5 is extremely low and, therefore, the cost of production is reduced.

Title: Video signal processing unit
Inventor: KANAZAWA MASARU
IPC: H04N9/69
Filed: 1993-12-14
Abstract: PURPOSE:To attain accurate color reproduction while keeping preferable gradation reproduction. CONSTITUTION:A signal processing circuit 5 applies inverse transformation of a gamma characteristic of a display device with a gamma of 2.8. When output signals r', g', b' are directly inputted to the display device, colors are reproduced accurately but gradation is not preferably reproduced. A signal processing circuit 6 obtains a 'representative signal level d' from received signals r, g, b and provides simply an output of a maximum value. The maximum value is used because no luminance is reduced for a fresh bright color. In the case of an input of (r: 1.0, g: 0.0, b: 0.0), the mean value is 0.33, and the correction of the difference from gamma indicates of multiplication of about 0.9 with respect to the level, and the color is unchanged on the display device but gets dark. When the maximum value is employed, the correction value is 1.0 to reproduce a fresh color.

Abstract: PURPOSE: To obtain a daily dish edible with a new unique taste in which a core material is mixed with a dough by rolling the core material comprising a daily dish of fishes and shellfishes in the Japanese-style confection dough having a new flavor according to a specific method. CONSTITUTION: Raw materials for Japanese-style confection such as an egg, sugar, wheat flour and rice flour are initially mixed with a seasoning such as salt or SAKE (Japanese rice wine), a foaming agent comprising carbonates and water and the resultant mixture is then formed into a flat beltlike shape and half-baked to afford a dough. A core material obtained by processing a roasted fish prepared by roasting a salmon or an eel or a processed product of fishes and shellfishes such as a walleye pollack roe into a suitable size so as to be edible is then placed on the dough and rolled therein to prepare a rolled material. The resultant rolled material is subsequently baked for several min until bubbles are produced in the interior and exterior of the dough.  Thereby, a baked material is obtained and finally branded to afford a daily dish, which is vacuum packaged so as to pressurize and sterilize the daily dish. The resultant package is then cooled to provide the objective product.

Filed: 1988-12-12
Abstract: PURPOSE:To realize a soliton transmission by exciting an Er fiber amplifier by means of a semiconductor laser light at a specific wavelength and amplifying and reproducing the optical soliton at the specific wavelength. CONSTITUTION:An Er fiber amplifying exciting light source 1' consists of a high output semiconductor laser at a wavelength 1.40 to 1.50mum. A dichromic mirror 2 makes the exciting light at a wavelength range 1.40 to 1.50 pass through, and reflects signal light at the range 1.53 to 1.56mum. Exciting light 1 and signal light 3 is transmitted and reflected with the use of a mirror 2, synthesized, guided to an optical soliton amplifying Er fiber 7, and an amplified optical output is guided to an optical fiber 4. The optical soliton amplifying Er fiber 7 is the Er fiber amplifier of a single mode optical fiber obtained by doping a rare earth element Er as a laser amplifying medium. It obtains a gain at 3dB/m, and obtains the gain at 10 to 15dB by the Er fiber 7 at a length 3 to 5m. Thus, since the soliton can be easily amplified by a small device, the soliton transfer is attained.

Abstract: PURPOSE: To utilize a flow passage space to a cylinder on one side as a flow passage space to a cylinder on the other side by connecting air supply passages to two inlet valves in such a way that a screw boss part for a cylinder head bolt is nipped therebetween. CONSTITUTION: In a cylinder head 1, air supply passages 9, 9' to inlet valves 4, 4, of a cylinder 2 are connected in such a manner that a boss part 18 is nipped therebetween, and air supply passages 10, 10' to inlet valves 5, 5' of a cylinder 3 are also connected in such a manner that the boss part 18 is nipped therebetween. Consequently, the inlet valves 4', 5 use a stream 19 in common, and the inlet valves 4, 5' use a stream 20 in common. As a result, since a flow passage space to the cylinder 2 can be utilized as a flow passage space by the cylinder 3 when the inlet valves 4, 4' of the cylinder 2 are closed, a large flow passage cross sectional area for filling air can be ensured.
