Title: Heat recording printer
Inventor: NOMURA ZENICHI
IPC: B41J2/36
Filed: 1990-06-29
Abstract: PURPOSE:To obtain the above heat recording printer which provides a uniform and constant density for each gradation by controlling a means for selectively transferring corrected data in a predetermined order and according to the information on gradation. CONSTITUTION:As the information on a line given to a corrected data producing circuit 10, the last two digits of the number assigned to the lines by the numerical order in which the lines are to be printed and in a binary-coded notation, are used. The storage elements 10a of which the corrected data producing circuit 10 are provided with specific preset data. When the printing is effected in the above-mentioned setting, the corrected values appear repeatedly every four lines in the output of the corrected data producing circuit 10. Since, in general, the printing device using a thermal head is capable of printing about 6-12 lines per 1mm, the printing repeated every four lines gives the human eyes such an illusion that the vision has the corrected value plus 1/4, whereby the generation of a correction pulse width being 1/4 of the minimum correction unit is realized.

Title: Induction heating rice cooker
Inventor: BETSUSHI TOKUJI
IPC: A47J27/00
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To obviate a cooling fan, and effectively use a lower dead space of a display panel by providing a base board where an electric circuit part is mounted on the opposite side of an inner pan, a display panel inclining downward to the side and a heat sink projecting in a space formed on the side of the base board. SOLUTION: When an inner pan 5 is heated by induction heating, its heat is transmitted not only to a heating object in the inner pan 5 but also to the front side of a rice cooker main body 1 by going over an inner body 2 and a protective frame 3. Since a surface on which an electric circuit part 13 of a base board 14 is not mounted is exposed to the front side of the rice cooker main body 1, heat from the inner pan 5 is reflected by this base board 14, and is hardly transmitted to the electric circuit part 13. A heat sink 15 extends up to a front side dead space through a rectangular hole 8 bored in a vertical wall part 7a of a base board holder 7. Moreover, in the heat sink 15, since an upper part and a side part are surrounded by a shielding rib 9 between the base board 14 and the vertical wall part 7a, the heat is hardly transmitted to an upper space.

Title: Starting controller for spark ignition type multi-cylinder internal combustion engine
Inventor: NODA TORU
IPC: F02D45/00
Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To certainly prevent a misfire due to insufficient of fuel supply to a part of cylinders after initial explosion, and improve start performance, by starting ignition after starting fuel is supplied to the whole cylinder at least one time. SOLUTION: When engine starting operation is executed, cranking is started by a controller 1, however at this time, when an initial REF signal is detected from a crank angle sensor 3, the width of this signal is compared with the number of POS signals and the like, thereby cylinder judgment is executed. At the same time, a starting fuel injection amount, fuel injection timing and ignition timing are calculated on the basis of information from a sensor detecting the condition of the engine of a water temperature sensor 4 and the like, and starting fuel is sequentially ejected to each cylinder. At this time, while ejection is executed from #1 cylinder, #2 cylinder meets ignition timing, however, ignition is controlled not to be executed until starting fuel is supplied to the whole cylinder, that is, to #4 cylinder.  Hereby, misfiring cylinders due to insufficient of fuel can be eliminated, and smooth start can be ensured.

Title: Liquid phase oxidation wet type desulsurization apparatus
Inventor: ONISHI SHOHEI
IPC: B01D53/14
Filed: 1989-07-07
Abstract: PURPOSE:To improve the gas-liquid contact efficiency, the clogging due to solid sticking, the cavitation due to bubbles, and the highly required power by communicating the lower liquid reservoirs of an absorption tower and an oxidation tower, and circulating the absorption liquid through a degassing vessel. CONSTITUTION:The matter to be oxidized in a gas 1 is absorbed and removed in a absorption tower 6, and an absorption liquid is accumulated in a lower liquid reservoir 18. This absorption liquid 3 unoxidized yet flows into a lower liquid reservoir 19 of oxidation tower 7 through a natural communication pipe 9 so that the need of liquid taking-out pump is eliminated. The matter to be oxidized is aerially oxidized by an air-liquid mixing unit 10 in the lower part of the oxidation tower 7, and the required power of an injection pump 14 and blower 15 is lowered because of the low level of liquid surface. Moreover, as the absorption liquid 5 containing bubbles after oxidation is subjected to the ari-liquid separation in a degassing vessel 8, a taking-out pump 16 is prevented from cavitation. A gase out phase oxidation system is modified into this system with low cost, and the gas-liquid contact efficiency and the solid sticking problem, etc., are improved.

Title: Digital/analogue converter
Inventor: GYOTEN TAKAAKI
IPC: H03M1/66
Filed: 1988-07-13
Abstract: PURPOSE:To prevent a phenomenon that an output signal is continued to be outputted even if an input becomes zero by permitting a low level detector detecting that a level continues more than a prescribed constant in input digital data to detect the input to be zero and controlling the output of a D/A converter to zero. CONSTITUTION:The addition circuit 2 of the D/A converter adds quantized digital input data D1 and output data Nq of a prediction filter 6 and a quantization unit 3 re-quantizes the output D1 of the circuit 2 so as to make it to be (m) bits. The relation of (m) bits and (n) bits of input digital data D1 at that time is set to be m>n. A quantization error detector 4 outputs the quantization error Nq of the quantization unit 3, the filter 6 inputs the error Nq of the detector 4, executes a filter processing by a prescribed transfer function, outputs a negative numeral and inputs it to the adder 2. The low level detector 1 compares data D1 with a constant Th and controls the D/A converter 5 so as to make the conversion output of the converter 5 to be zero when 'zero' of data D1 is continuously detected for more than a prescribed time.

Title: Compressor
Inventor: OGURA MASATOSHI
IPC: F04C29/02
Filed: 1982-10-06
Abstract: PURPOSE:To separate oil effectively from low speed to high speed rotation of compressor by partitioning chamber into two and providing oil separators having different function respectively. CONSTITUTION:Under high speed operation of compressor, oil separated in a delivery pressure chamber 9 will assure minimum supply even if collection of separated oil from an oil separation chamber 12e has delayed. Under low rotation of compressor, flow speed of refrigerant to be delivered through a delivery port 12c is lowered to reduce oil separation effect due to expansion of refrigerant in the delivery chamber 9 but since the time required for passing through said chamber 12e is lengthened, oil separation effect is improved. Under high speed, a separator where separated oil is collected quickly will exhibit effect while under low speed, another separator having high separation effect will function thus to perform effective oil separation from low to high speed.
