Title: Solid fuel firing stove
Inventor: HATSUTA RIYUUTAROU
IPC: F24B1/10
Filed: 1980-05-13
Abstract: PURPOSE: To burn completely and smokeless and minimize the occurrence of public nuisance by a method wherein there are provided a circular arc shape grate equipped with a coal feeder therewithin and a secondary air discharge port above the inlet of a combustion chamber.  
     CONSTITUTION: The grate 9 is formed and inclined within a coal storage chamber 2 and in a circular arc shape at the lower part of the combustion chamber 3. The feeding of coal at a proper rate is performed by the coal feeder 10 provided on the grate 9 and reciprocated with crank mechanism. The mesh of the grate 9 is somewhat fine as to prevent unburnt solids from falling down therefrom. The secondary air is regarded as of major importance in combustion and consequently the discharge port 14 is provided above the inlet of the combustion chamber in order to discharge the air flow necessary enough for combustion obliquely aslant and downwards. Furthermore, the combustion chamber 3 is taken up enough room for unburnt gas to burn completely. As a gas burner 16 is used for ignition, so the smokeless combustion is possible immediately after the lighting of coal.

Title: Image processing unit and image processing method
Inventor: SUMIYA SHIGEAKI
IPC: B41J2/525
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To improve image quality around a low density area by dividing image data in the low density area of a color space finer than the data in other areas, storing correction data to coordinates of a lattice point in the color space, transforming the data into coordinates of the lattice point and reading the correction data at the lattice point. SOLUTION: A color space is divided into lattice points and correction data of each color component are stored in each lattice point 300. In the case of desiring a corresponding color, gradation correction data of each color component of R, G, B to be required are checked for each lattice point 300 and the result is stored in a color correction table memory. A proper division number is decided based on the balance between the capacity of the color correction table and the image quality. That is, a pre-conversion of gradation number is performed so that received original color data ORG are color data on a lattice point of a color correction table memory, and then color correction is conducted by referencing the color correction table memory and then post- gradation number is performed. Thus, complicated interpolation arithmetic operation is omitted.

Title: Optical fiber measuring element
Inventor: TSUKUNI HIROYUKI
IPC: G01N15/06
Filed: 1988-03-15
Abstract: PURPOSE:To convert the pressure and density of a fluid atmosphere to be measured directly to a light signal by providing an optical fiber of a single body as a light emitting part and optical fibers which lie in a row as a light receiving part to the fluid atmosphere to be measured and to an atmosphere as a reference. CONSTITUTION:Laser light 1 is emitted from the optical fiber 2 of the light emitting part and is entered to the optical fibers 3 of the light receiving part. The fluid atmosphere 4 to be measured and the reference atmosphere 5 for the purpose of comparison are set in this embodiment, in which the atmosphere 4 is set as the light emitting part side atmosphere 6 and the atmosphere 5 as the light receiving side atmosphere 7. The laser light 1 is bent in course by a difference between the refractive index n1 of the atmosphere 6 and the refractive index n0 of the atmosphere 7. Since the bending angle of this time is unequivocally determined by the respective refractive indices n1, n0, the course of the laser light 1 can be determined by the fluid atmosphere to be measured if either of the atmosphere 6 or the atmosphere 7 is determined as the reference atmosphere and the other as the fluid atmosphere to be measured.

Title: Stress measuring apparatus utilizing iron loss
Inventor: NAKAMURA TADAMASA
IPC: G01R33/12
Filed: 1979-05-23
Abstract: PURPOSE: To improve the measuring accuracy by making the hysteresis loss larger than the over current loss with the primary coil of the magnetic sensor utilizing iron loss excited by the square wave AC voltage.  
     CONSTITUTION: The AC power to the primary coil 4 causes the magnetic flux outputted from the magnetic sensor 3 to flow in parallel along the stress of the magnetic material 1 to form the closed magnetic circuit through the magnetic core 6 of the  sensor 3. Therefore, the magnetic characteristic of the material 1 varies with the  stress thereof. The iron loss is converted to the stress by the iron loss detection part  14 composed of the secondary coil 5 of the sensor for extracting the corresponding  secondary voltage, the voltmeter 8, the power meter 9 and the arithmetic circuit 10,  where the stress is indicated on the indicator 11. In this case, when the square  wave AC voltage is applied on the coil 4, the hysteresis loss exceeds the over current loss so much that the hysteresis loss in the iron loss directly related to the  coercive force related with the material 1 is allowed to be detected thereby improving the measuring accuracy.

Title: Dry recording method
Inventor: SUZUKI KATSUMI
IPC: G03G15/20
Filed: 1980-05-14
Abstract: PURPOSE:To prevent a recording form from being stained by setting the longer carriage time of the recording form between a heat-fixing device and a carriage roller than the time when toner particles solved by the heat-fixing device are solidified by being cooled. CONSTITUTION:A carriage roller 11 is at a distance L2 from a fixing device 6 and this distance is greater than the distance L1 of a conventional device. This distance L2 from the heat-fixing device 6 is so determined that toner particles t0 solved by the fixing device 6 on a recording form P will reach the carriage roller 11 after being solidified completely. None of toner particles t0, therefore, sticks to carriage roller 11, which never gets stained, so that the recording form will not be stained.

Title: Alloy for seal-bonding glass and its manufacture
Inventor: SAKAMOTO DAIJI
IPC: C22C38/52
Filed: 1980-05-13
Abstract: PURPOSE: To obtain an inexpensive alloy with sufficiently high reliability by adding a relatively small amount of Cr and/or Co to an Ni-Fe alloy.  
     CONSTITUTION: This alloy is obtd. by adding 1W3wt% Cr and/or 0.5W5wt% Co to an alloy consisting of 37W43wt% Ni and the balance essentially Fe. After applying a cold working strain, the alloy is annealed in a wet hydrogen atmosphere under about 10 -22 W10 -18  atm. partial pressure of oxygen to obtain a product. By adding Cr and Co to such an Fe-Ni alloy, an oxide film is made dense to enhance the adhesion to the base alloy. Cr and Co added in excess of the upper limit result in an excessively low transition point and an excessively high coefft. of thermal expansion, respectively. By further adding about 0.05W0.35% Si to said composition, the adhesion of the oxide film to the alloy is enhanced to increase the seal bonding strength, yet excess Si lowers the transition point and increases the coefft. of thermal expansion excessively.
