Abstract: PURPOSE:To improve efficiency of a system and reduce blower power by providing a nitrogen oxide reducing method comprising a supplying process for supplying hydrogen gas, and a reducing process for applying contact reduction to combustion exhaust gas in which the hydrogen gas is supplied in a catalyst device at a low temperature atmosphere 250 deg.C or less so as to reduce nitrogen oxide. CONSTITUTION:The combustion device of a stirling engine comprises a combustion chamber 1, a fuel supplying part 2 for supplying fuel into the combustion chamber 1, an air supplying part 3 for supplying air, a discharging passage 4 for discharging exhaust gas from the combustion chamber 1, a catalyst device 5 arranged in the discharging passage 4, and a hydrogen gas supplying part 6 connected to the discharging passage 4 passing the inside of the combustion chamber 1. In the hydrogen gas supplying part 6, nearly 80 weight% in a mixture made from fuel and water becomes hydrogen was by heat in the combustion chamber 1, and then supplied into the catalyst device 5 in the discharging passage 4. It is thus possible to reduce and eliminate nitrogen oxide in exhaust gas discharged from a combustion device by such a way that hydrogen gas is supplied, and then contact reduction is applied to the gas in the catalyst device 5.

Title: Semiconductor integrated circuit device
Inventor: SUZUKI KAZUHISA
IPC: H01L27/092
Filed: 1999-08-23
Abstract: PROBLEM TO BE SOLVED: To reduce leakage currents in a MOS transistor, while the generation of a punch-through in the P-N junction part formed in a triple well at the measurement of a stand-by current is prevented in a semiconductor integrated circuit device. SOLUTION: An inverter 1 of a CMOS constitution consists of a transistor 2, which is formed into a triple well and is provided in an N-type well 5 formed in a P-type semiconductor substrate 4, and a transistor 3, which is provided in a P-type well 6 formed in the well 5. The threshold voltage of the transistor 2 is set high, and the threshold voltage of the transistor 3 is set low. At the measurement of a stand-by current, a supply voltage VDD is applied to the well 5 as a well potential and a well potential VSBB=VSS+β (β=1.5 V or thereabouts) is applied to the substrate 4 and the well 6. Thereby, since a voltage which is applied between the P-N junctions in the respective transistors 2 and 3 can be made low, generation of a punch-through in the P-N junction part formed in the triple well at the time of the measurement of the stand-by current is prevented, and a leakage current in the transistors 2 and 3 can also be reduced.

Title: Facsimile transmission reception method and transmitter-receiver
Inventor: SUZUKI TADAAKI
IPC: H04N1/387
Filed: 1990-09-06
Abstract: PURPOSE:To prevent a small original at a receiver side from being printed out with reduction by allowing a sender side to convert picture element data in a same sequence as the read of main scanning along a short side direction of the original when the original is read through main scanning along the long side direction of the original. CONSTITUTION:Picture element data read from originals set in mixture and with different sizes by a read section 1 through the main scanning in a direction orthogonal to the moving direction of the originals are stored in a storage section 3 and an original discrimination section 2 discriminates the set direction of the originals. Then a data conversion section 4 reads the picture element data while the order of the main scanning and the subscanning is replaced when the main scanning is implemented along the long side direction of the set original and reads the picture element data in the same order as the read of the original when main scanning is implemented along the short side direction of the set original. The picture element data read in this way are sent sequentially via a transmission section 5. When the read picture element data is printed out by a print section 7, the data is reproduced with nonmagnification or reduction depending on the size of the reproduced original and the width of the print paper.

Title: Symbol reader
Inventor: OKAMURA HIDEKI
IPC: G06K7/015
Filed: 1989-09-11
Abstract: PURPOSE:To surely read a symbol attached onto a reading surface despite the small error of the angle of an image sensor by turning the sensor in order to change the visual field position corresponding to the reading surface of the image sensor. CONSTITUTION:A head 1 is moved while touching to a symbol 2 or the symbol 2 is moved while touching to the head 1. Thus an image sensor 5 receives the reflected light from the symbol 2. If the head 1 is tilted, the symbol image moves on the sensor 5. Thus a process circuit 8 detects the tilt of the head 1 based on the movement of the symbol image. When the symbol image reaches the rotational center part of the sensor 5, an element corresponding to the rotation center part receives and detects the reflected light from the symbol 2 to drive a rotary means 11. Thus the sensor 5 is turned by a prescribed angle. As a result, the symbol image is totally included in the visual field of the sensor 5 and the symbol 2 is surely read.

Abstract: PURPOSE:To allow a key to be struck under a specified regulation by performing the relative positioning of a stroke rod and a piston hammer for advancing the stroke rod toward the key with air pressure by a cylinder and a rod holder. CONSTITUTION:Air in an air tank 31 is led into a cylinder 16 through a first port 18 by a first change-over valve 30 so as to move a piston hammer 28 in the cylinder 16 toward a forging machine. The hammer 28 then collides against the rear end of a stroke rod 26, thus providing a key with impact force through the rod 26 and a jig 22 at the front end of the rod 26. In this case, the relative positioning of the piston hammer 28 and stroke rod 26 is performed by the cylinder 16 and a rod holder 21, and the piston hammer 28 is struck against the stroke rod 26 without missing the aim. In this stroke, the air in the air tank 31 is led also into the operating cylinder 54 of a rapid exhaust valve 51, so that through its operating piston, a valve body is moved in the receding direction from the rod holder 21, thus releasing an air passage 52a communicated with a second port.
