Title: Measuring apparatus for rotation period of internal combustion engine
Inventor: NAKANIWA SHINPEI
IPC: F02B77/08
Filed: 1990-08-30
Abstract: PURPOSE:To improve the accuracy in diagnosis for accidental fire and the like based on the measured result of a rotation period by compensating for the measurement errors of the rotation period even if there is dispersion in positions in production at a part to be detected which is provided on a rotary body that is rotated in synchronization with the rotation of an engine. CONSTITUTION:A signal disk plate 5 is supported with a cam shaft so that protruding parts 5a - 5f are detected with an electromagnetic pickup 6 at a position of a specified crank angle in each cylinder. The output pulses from a waveform shaping circuit 9 and a waveform shaping circuit 10 which rise up at every specified crank angle are inputted into a control unit 11. The unit 11 detects the range of the specified crank angle based on a unit crank angle signal POS and a reference crank angle signal REF and also detects the rotation period within the range of the specified crank angle. The unit 11 is provided with the functions as a rotation period measuring means, a rotation period deviation operating means and a rotation period correcting means as software. The deviation of the period is corrected based on the dispersion of the sensors for detecting the crank angle in production and the data of the periodic dispersion in the cylinder wherein normal combustion is performed. Thus, the erroneous detection can be suppressed, and the reliability in accidental fire detection can be improved.

IPC: G02B7/28
Filed: 1985-10-14
Abstract: PURPOSE:To constitute a useful micro-optical pickup by detecting a focus position error signal of a light spot to an optical information storage medium, from a difference signal of detecting outputs of the first and the second photodetectors. CONSTITUTION:A light wave which is emitted from a semiconductor laser 1 is propagated in an optical waveguide layer 10, and reaches an unequal interval curve diffraction grating 3 through a thin film lens 2. Subsequently, by the grating 3 which is brought to an irregularity working by the cutting work of an electron beam lithography equipment the light wave forms light spots 50a,50b, and 50c on an optical disk 30 being in the upper part on the grating, or its vicinity. On the other hand, on optical waveguide layers 20a, 20b, and 20c, unequal interval curve diffraction gratings 13a, 13b, and 13c are provided, the light wave which is reflected by the disk 30 is led to the layers 20a, 20b and 20c, and the reflected light which is propagated through each layer passes through thin film lenses 12a, 12b, and 12c, and reaches photodetectors 11a, 11b, and 11c. In such a case, the reflected light forms symmetrically virtual spots 50a, 50c against the light spot 50b, therefore, from a detecting signal difference of the detectors 11a, 11b, a focus error signal is obtained.

Abstract: PROBLEM TO BE SOLVED: To provide bearing parts provided with a bearing portion having good wear resistance in a simple process and sintered forged parts which can dissolve such problem as to lower the strength caused by a decarburization phenomenon. SOLUTION: Thermal-spraying is executed by keeping a large diameter side upward so that jetting from a thermal spraying gun 7 effectively executes to the inner surface of the bearing portion. A copper alloy base or molybdenum base metal is thermally sprayed to form the thermally sprayed layer 8 having a prescribed thickness (about 200-300 μm) onto the inner surface of the beating portion. To a portion afraid of the lowering of the strength caused by the decarburization on such as the neck part of a connecting rod, the thermal spray of about 10-30 μm thickness is executed. The thermal spray is executed by melting a metallic material of the copper alloy wire, forming a foggy state of the molten metal with gas pressure and spraying it on the surface of the object product.  The formed body having the metal film, is sintered at about 850 deg.C and a hot-forging is exected at about 850-1,100 deg.C.

Filed: 1993-09-14
Abstract: PURPOSE:To output a projection value capable of accurately reflecting a received field image by preventing picture data in a received field image element from being overlappedly used at the time of computing a projection value. CONSTITUTION:An address generating part 26 executes the coordinate transformation of respective picture element addresses (rho0, ai) (provided that i=0 to n) in a projection grid in which a value in the rho axis direction is rho0 when a projection direction angle is theta0 to find out picture element addresses (xi, yi) in the receiving field and an overlapped address detecting/correcting part 27 checks whether the picture element addresses are overlapped or not. When there is no overlapped addresses, address correction is not executed and a projection value computing part 30 integrates picture data specified by respective picture element addresses (xi, yi) to find out the projection value of rho=rho0. When there are overlapped addresses, an overlapped address detecting/correcting part 27 corrects one address to a prescribed adjacent address and the computing part 30 integrates image data specified by corrected picture element addresses to find out the projection value of rho=rho0.
