IPC: F02B19/16
Filed: 1996-07-31
Abstract: PROBLEM TO BE SOLVED: To reduce NOX in exhaust gas, by setting a fuel gas supply amount so that a fuel gas concentration approaches the upper limit of a fuel gas combustible ranges in an auxiliary chamber, becomes within the combustible range in the vicinity of the ejection hole of the auxiliary chamber in a combustion main chamber, and becomes in a super leak condition in the combustion main chamber. SOLUTION: An air supply passage 1 and an exhaust gas passage 7 are communicated with a combustion main chamber 8 in the upper space of a cylinder, in which a piston P is arranged, and also an auxiliary chamber 5 is communicated with the combustion main chamber 8 through an ejection hole 5a, and a fuel gas supply valve 3 and an ignition plug 4 are placed on the upper part of the auxiliary chamber 5. Then, the other fuel gas supply valve is arranged on a side further upstream from the air supply valve 2 of the air supply passage 1, and fuel gas is supplied to introduced air to the air supply passage 1 so as to form a lean fuel gas mixture and feed it to the combustion main chamber 8.  At this time, a fuel gas supply amount from the fuel gas supply valve 3 is so set that an air-fuel mixture concentration in the auxiliary chamber is enhanced more than the conventional case, and an air-fuel mixture concentration in the main chamber, which is originally set lean, is also set lower so as to reduce NOX to more extent.

IPC: C30B33/00
Filed: 1987-08-13
Abstract: PURPOSE:To increase resistivity with flatness being maintained, by annealing a GaAs compound semiconductor crystal in an ingot state, slowly cooling the crystal down to room temperature, cutting the crystal into wafers, performing a specified heat treatment, and thereafter performing polishing so as to obtain a mirror surface. CONSTITUTION:A GaAs compound semiconductor crystal, which is obtained by a liquid sealing lift-off method, is annealed in an ingot state and slowly cooled to room temperature. The crystal is cut into wafers. Thereafter, heat treatment is performed as follows: the wafer is heated to a temperature of 700 deg.C or more; then, the wafer is rapidly cooled from the temperature of 700 deg.C or more down to the temperature of 400 deg.C or less within 30 minutes; and then the wafer is cooled to room temperature. Thereafter, polishing is performed so as to obtain a mirror surface. Resistivity can be increased by heating the wafer crystal again and rapidly cooling the crystal in this way. Thus the flatness, which is the characteristic obtained by ingot annealing, is made to remain intactly, and the crystal having the high resistivity as a whole is obtained.

Title: Control rod driving device
Inventor: KATAGIRI SHIGEO
IPC: G21C7/14
Filed: 1988-08-17
Abstract: PURPOSE:To prevent crushing due to buckling by limiting the direction of curvature due to buckling to a direction of separation from the center of the control rod driving device when the pressure of a stand pipe inside drops and a compressive load is placed on a support member. CONSTITUTION:The longitudinal section of the support member 39 is shaped not in a conventional rectangular shape, but in such a shape that sides close to the center axis of the control rod driving device among the sides constituting the rectangle are curved having their centers of radii of curvature on the center axis side. Consequently, when the compressive load which is axially large is placed on a column in the longitudinal section shape, the direction is specified to the stand pipe side to lead the buckling. The stand pipe with high rigidity is close on the stand-by side, so the deformation of the column is limited to the stand pipe and the quantity of deformation is a little even in the case of the buckling, so that variation in the axial length of the control rod driving device is a little. Further, the member 39 deforms outward, so the member 39 never interferes with components of the control rod driving device.

Filed: 1985-09-13
Abstract: PURPOSE:To avoid such a case where the wrong data are stored in a storage means by inhibiting the restoring of data when a saving action is interrupted owing to the generation of a fault and others. CONSTITUTION:A data storage control circuit 3 resets a data saving instruction part 5 before the data stored in a memory 2 is saved to a magnetic disk device 4 and then saves the data. Then the circuit 3 sets the part 5 when the saving of data is through in a correct way. In case some fault occurs while data are saved and the data saving action is interrupted, the part 5 is kept reset as it is. Then the circuit 3 checks the part 5 when the data saved to the device 4 are stored again in the memory 2 and stores the data again as long as the part 5 is set. While these data are not stored again if they are reset.

Title: Defect detector of shaft symmetrical object
Inventor: FURUKAWA SATOSHI
IPC: G01N21/88
Filed: 1983-10-31
Abstract: PURPOSE:To allow detection of a defect of a shaft-symmetrical object at high speed and with a simple constitution by comparing signals following a symmetrical shaft of picture signals of the second frame and stored picture signals which are read reversely from a memory, and by detecting asymmetry by the defect. CONSTITUTION:This circuit is operated by two-time frame scanning of a picture signal of TV camera output which is obtained as video input. At the first scanning, the picture signal is made binary by an analogue comparator. At the second scanning, the picture signal is A/D converted by an A/D convertor 3, and inputted to an FIFO/LIFO4. The FIFO/LIFO4 has two modes. The FIFO/LIFO4 which is in a FIFO mode first becomes a LIFO mode and outputs reversely data before an address Xc, and therefore, these waveform data are compared with picture data which are outputted from the A/D convertor 3. When a shaft-symmetrical object has stains or deformation, the difference of the subtracted results becomes larger, and therefore, detection is possible by a digital comparator 7 through an integrator or adder 6 in accordance with necessity.
