Abstract: PROBLEM TO BE SOLVED: To enable utilization of the original material such as low quality charcoal, heavy oil, and biomass as a fuel by continuously supplying the fluid fuel including the organic material and the alkali solution to a heat exchanger integrated burner, and burning the organic material underwater at a temperature and a pressure near supercritical state. SOLUTION: Organic material 1 is mixed with water by a slurry adjusting unit 2 so as to adjust the fuel slurry as a fluid fuel. The slurry and the alkali solution 3 are pressurized by each pump 4, 5 so as to be passed through a waste heat recording heat-exchanger 6. Heat from the mixture fluid is exchanged by the heat of the fluid flowed out of a heat exchanger integrated burner 7, and temperature of the mixture fluid becomes 400-700 deg.C. The heated mixture fluid is supplied to a heat exchanger integrated burner 7, and the air 8 as the oxidant gas is compressed by a compressor 9, and passed through the heat exchanger 6 for heating, and the compressed and heated air is supplied to the burner 7.  The organic material included in the mixture fluid is burned with the oxygen included in the air, and steam is generated by the combustion heat of the heat exchanger integrated burner 7, and electrical energy is extracted by a power generator 11.

Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for keeping a part of image data secret, opening them to public and keeping the secret information in the image data so as to be restored only by a specified information obtaining person. SOLUTION: A part 11 for keeping information secret restorably keeps secret a specified secret area in original picture data 2 by a specified system for keeping secret, prepares watermarked image data 3 by watermarking restoration information for returning the secret area to the original picture data in the original picture data 2 and preserves information to be a key for obtaining the restoration information as key information 4. An information restoration part 12 obtains the watermarked restoration information by the key information 4 and restores the image data in the secret area by the restoration information. In the case of keeping character information secret, a character display area for displaying an inputted character string later can be set in the image data instead of providing the secret area.

Title: Nonaqueous electrolyte secondary battery
Inventor: MATSUI TORU
IPC: H01M4/485
Filed: 1985-04-16
Abstract: PURPOSE:To form a nonaqueous electrolyte secondary battery having excellent charge/discharge behavior by employing a mixed crystal of MnO2 and chrome oxide as positive electrode active substance. CONSTITUTION:The positive electrode active substance is a mixed crystal of MnO2 and chrome oxide having Cr/Mn atomic ratio in the range of 0.02-0.2. When employing such active substance, expansion/shrinkage of the active substance particles due to intrusion/emission of alkali metal ions such as Li<+> through charge/discharge is low thus to reduce separation from conductive agent particles such as carbon black. Consequently, the current collecting condition is good even after repetition of charge/discharge cycle thus to suppress degradation of cycle. It will never function when Cr/Mn atomic ratio is lower than 0.02 while effective only for a primary battery when said ratio will exceed over 0.2 because of production of complex oxide of Mn and Cr and not preferable as secondary battery in view point of cycle characteristic.

Title: Crankshaft bearing of engine
Inventor: YAMAMOTO YUKIO
IPC: F02F7/00
Filed: 1988-04-01
Abstract: PURPOSE:To eliminate the generation of thermal stress on an abutting surface and to prevent vibration, noise and lowering of hydraulic pressure, by forming a crankshaft bearing part from light metal containing reinforcing fibers, and by giving a specific relationship to the volumetric rate of the reinforcing fibers. CONSTITUTION:A crankshaft bearing structure 1 in an engine supports a crankshaft 5 made of steel, and is made of light metal containing reinforcing fibers. The volumetric rate Vf (abscissa) of an inner peripheral part 9 does not vary with the distance (I) (ordinate) from its innermost layer 6c, but the volumetric rate Vf of an outer peripheral part 10 linearly decreases with the distance (I). Thus, since no thermal stress occurs on an abutting surface and a necessary rigidity is ensured by reinforcing fibers, it is possible to prevent vibration, noise and lowering of hydraulic pressure.

Title: Sensor for molten metallic level of low melting point metal
Inventor: INOUE SUSUMU
IPC: B22D17/30
Filed: 1980-06-18
Abstract: PURPOSE:To improve sensitivity, prolong life and facilitate maintenance and inspection by using a recrystalline silicon carbide molding in making the sensitive part of a sensor for molten metallic level to be installed in the automatic molten metal charger of a die casting machine. CONSTITUTION:The sensing part of a sensor 3 for molten metallic level to be installed in the crucible 1 of an automatic molten metal charger which feeds molten metal into a die casting machine is made of a recrystalline silicon carbide molding. Since the silicon carbide molding is hard to be wetted with molten metal 2 of low m.p. metals such as Al, Zn, or their alloys, no metal sticks on the surface of said molding. Since no oxide films are formed, detecting current is not blocked, and the initial sensitivity of the sensor is retained. This molding is not eroded at high temps., and is so hard that it is hard to break down. Hence, it is long in life. This sensor 3 retains the initial sensitivity and has a long life in spite of absence of maintenance; therefore, it offers saving of manpower and costs.

Title: Optical disk device and its recording and reproducing method
Inventor: YAGI KOSUKE
IPC: G11B11/10
Filed: 1994-04-20
Abstract: PURPOSE:To obtain an optimum ultra resolution phenomenon by reversing the rotational direction of a motor and switching the order of front and rear of reproducing data employing a memory during a reproducing and performing a track jump so as to keep the order of the data during a reverse reproducing. CONSTITUTION:During a reproducing, the rotational direction of a magneto- optical disk 2 is reversed and a reproducing is performed. At that time, the thermal distribution generated on an ultra resolution film is made reverse to the case of a normal rotation by reversing the rotational direction of the disk 2. By that means, the directions of crescent moon shaped reproducing spots by a magnetic ultra resolution phenomenon are made to match. Thus, the entering of the information of the pits adjacent to the line direction into reproduced signals is prevented and the signals which are recorded with a high density are accurately reproduced. On the other hand, the signals, which are reproduced through an optical head 1, are temporarily stored in a memory 11 through a reproducing amplifier 9 and a demodulation circuit 10. When data are taken out for data address switching, the memory 11 switches the order of the data and performs a track jump so that the data are read in correct order.
