Title: Combustion noise detecting device of internal combustion engine
Inventor: MATSUNAGA AKIO
IPC: F02D45/00
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To accurately detect a combustion noise of internal combustion engine. SOLUTION: A combustion noise sensor 15 for detecting a combustion noise is provided to a diesel engine 1 to input an output of sensor 15 to an electronic control unit(ECU) 20 via a filter circuit 17, a gate circuit 18, and a peak hold circuit 19. The ECU calculates a fuel injection timing AINJ to each cylinder and an ignition lag time aTBD in the cylinders based on an engine operating state. An output timing AGOP (crank angle before a top dead point) of a gate open signal to the gate circuit 18 is calculated as AGOP=AINJ-(aTBD+aTSD +aTED-aTGD) using a detection lag time aTSD of the sensor 15, a lag time aTED of the filter circuit 17, and operation lag time aTGD of the gate circuit 18. Accordingly, a combustion noise can be accurately detected at start of combustion in the cylinder thereby performing the combustion noise detection in which an influence of noise is eliminated.

Title: White level signal control circuit
Inventor: OCHIAI MASASHI
IPC: H04N9/73
Filed: 1992-08-21
Abstract: PURPOSE:To properly change a voltage at a white level signal suppression level corresponding to both of a screen midposition and a screen circumferential part. CONSTITUTION:A white signal level control circuit 1 suppresses a white level signal and outputs a resulting composite video signal b1 to a cathode of a picture tube 12 via a video amplifier 11 while a white signal level is changed with a voltage V11 at a connecting point P11 between a horizontal deflection coil Lh1 and an S-shaped correction capacitor C1 in a horizontal output circuit 21 with respect to an input composite video signal a1 from a video signal processing circuit led to an input terminal 2. An output composite video signal b1 is shaped to be a sinusoidal curve in which the signal level is decreased for the scanning period when an electron beam of the picture tube 12 is deflected toward the screen circumferential part and increased for the scanning period when the electron beam of the picture tube 12 is deflected toward the screen center. Thus, the voltage for the white signal suppression level is properly changed to both the screen midposition and the screen circumferential part.

Title: Piping leakage detecting device
Inventor: NISHINO HIROO
IPC: G08B21/16
Filed: 1994-09-19
Abstract: PURPOSE: To detect gas leakage in its early stages with simple constitution by arranging a differential pressure regulating valve having a function to reduce outlet pressure more than inlet pressure in the middle of a main pipe line, and arranging a bypass pipe line to communicate the inlet and the outlet sides of the differential pressure regulating valve with each other. CONSTITUTION: Pressure equal to or slightly higher than a pressure loss caused when a minute flow rate to be detected for leakage is made to flow into a bypass pipe line 3, is set in a differential pressure regulating valve 2. When gas is consumed outlet side pressure is reduced to a preset value or more, and the valve 2 is opened, and gas flows into a main pipe line 1, and at the same time, the gas slightly flows even into the pipe line 3. When gas consumption is finished and gas leakage is not caused, after the valve 2 is closed, the gas flows until inlet and outlet pressures become uniform, and a gas flow stops in both pipe lines 1 and 2, and a measured valve of a minute flow rate measuring device 4 becomes 0. Even if the consumption is finished, when leakage exists in the downstream of the pipe line 1, it is put under prescribed differential pressure at the time of minute leakage, and after the valve 2 is closed, the gas corresponding to a leakage quantity continuously flows from the pipe line 3, and since the measured value of the device 4 does not show 0, the gas leakage can be detected.

Title: Cylinder judging method for internal combustion engine and signal generating device for cylinder judging thereof
Inventor: AOKI SHIGETOSHI
IPC: F02D45/00
Filed: 1990-08-24
Abstract: PURPOSE:To surely judge each cylinder even when an engine is quickly accelerated/ decelerated in revolution by judging each cylinder by counting the number of specified cylinder judging pulses. CONSTITUTION:A signal generator 14 generates homopolar reference signals for each cylinder at each reference position set for each cylinder of a multi-cylinder internal combustion engine, and the shapes of the respective reluctors 13a through 13c of a rotor 13 are concurrently set up in such a way that cylinder judging pulses different in polarity from the reference signal for each specified cylinder are generated by set numbers at positions spaced in specified phase relation with the reference position of each specified cylinder. And when the set number of cylinder judging pulses are counted, it is judged that the reference signal which is in specified phase relation with the aforesaid cylinder judging pulses, is the reference signal of the specified cylinder. In the case of other reference signals, each cylinder having another reference signal is judged based on the reference signal corresponding to the specified cylinder. By this constitution, the cylinder can thereby be surely judged even when the engine is operated at high speeds.

Title: Boiling water reactor and fuel loading method thereof
Inventor: AOYAMA TADAO
IPC: G21C5/12
Filed: 1989-08-30
Abstract: PURPOSE:To reduce a void coefficient without losing the characteristics of a core by setting the ratio H/D of the equivalent diameter D and effective length H of the core to 0.2<= H/D <=0.3 within a range of 0.2 - 0.3. CONSTITUTION:The amount of neutrons leaking from a core 2 has action reducing a void coefficient and, in order to promote the effect thereof, a back ring B<2> may be increased. Under a condition keeping a core volume constant, the ratio K of the equivalent diameter D and effective length H of the core 2 is set to 0.92 or less and B<2> can be increased as the ratio K shifts from said value. That is, the void ratio can be reduced as the core 2 becomes flat and the value of K may be set to 0.3 or less in order to hold the void coefficient to a reference value. Since the reaction degree of the core 2 is lowered with an increase in a neutron leak amount, it is necessary to suppress the increase width of a fissionable Pu wt. ratio to 1 w/0 or less and, therefore, the value of K may be set to 0.2 or more.

Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To enable always photographing in a satisfactory state, at the time of mounting a film adapter by moving a lens to a prescribed focal distance where a picked-up image is of a prescribed size. SOLUTION: At the time of driving a zoom lens 103 and a focusing convex lens 106 when respective motors 110 and 112 for driving a lens are stepping motors, a lens/camera control part 118 sends a motor rotation frequency signal according to a driving speed and a motor rotating direction signal according to the driving direction to motor drivers 113 and 115. At the time of mount- moving the film adapter, while the zoom lens is forcedly driven to a prescribed focal distance making arbitrary image angle, the focusing convex lens is forcedly driven into a position which focuses on a subject at a prescribed distance with a prescribed focal distance. Thereby, a phenomenon where the sizes of films projected on a screen vary, focusing takes a long time, etc., are avoided.
