Title: Ignition timing control device for internal combustion engine
Inventor: MATSUMOTO KENJI
IPC: F02B77/08
Filed: 1995-05-31
Abstract: PURPOSE: To prevent omission of an ignition signal during the rapid change of the number of revolutions of an internal combustion engine and to generate a constantly optimum ignition signal, in an ignition signal generating device used in the internal combustion engine. CONSTITUTION: An internal combustion engine rotation angle sensor signal compares with a threshold value by using a comparator 10. When an elapse time beginning from the starting side of a pulse signal, the waveform of which is shaped, coincides with a precalculated ignition timing, an ignition timing signal is outputted to an ignition device. In a threshold, an elapse time from a pulse signal generated by differentiating the output of a comparator 10 by a differentiating circuit 11 is measured by a timer 12. By changing the threshold according to the elapse time by using a correction circuit 13 and a D/A converter 14, the timing on the starting side of a waveform shaping pulse is set in such a manner that an angle is kept at a constant value.  A ratio between the time on the (H) side and the time on the (L) side of the waveform shaping pulse is calculated and a rotation fluctuation amount is corrected based on an ignition timing.

Title: Induced-angle sensor for measuring rotation of shaft
Inventor: GIYUNTAA FUEHETO
IPC: G01B7/30
Filed: 1991-06-05
Abstract: PURPOSE: To simplify the structure and to obtain an accurate measurement signal by constituting a short-circuiting unit in a pot state at a base, and forming two protrusions protruding between a plurality of legs provided at an E-shape core to be extended in opposite directions. CONSTITUTION: The protruding parts 17, 18 of a detector 12 are reciprocatingly moved between the legs 30 and 32 of a core 33 at the time of rotating a steering column. When an AC current flows to measuring coils 34, 35, eddy currents are inducted at the parts 17, 18. Thus, the extensions of the magnetic fields of the coils 34, 35 are limited in response to the shapes of the parts 17, 18, and the inductances of the coils 34, 35 are varied. The inductances are evaluated by an electronic unit as the amount of penetrating depth at each time. Reverse measurement signals are formed in the coils 34, 35 based on the shape formed oppositely at the parts 17, 18, but the quantitative changes are the same. Thus, the signal can be differentially evaluated in the unit.

Title: High frequency attenuator
Inventor: TORII TOSHIHIRO
IPC: H03H7/24
Filed: 1990-05-24
Abstract: PURPOSE:To bring the VSWR (voltage standing wave ratio) to a value close to '1' to improve the frequency characteristic by preparing three sets of impedance devices each comprising a resistor and a capacitor connected in series, connecting these impedance devices in a form of T or pi, and inserting the connected impedance devices between both terminals of a series of resistances of an attenuator and ground. CONSTITUTION:An attenuation ratio at a DC and a low frequency component is decided by resistors R2,R3,R4. The reactance of capacitors C11,C12,C13,C5 is smaller than the resistance of the resistors R2, R3 at high frequencies. Thus, the attenuation ratio and the input impedance at high frequencies depend on impedances Z11,Z12,Z13,Z5. With a switch 12 closed, the resistance R4 (1Mohm) of the resistor R4 is negligible with respect to the inductance L1 of an inductor L1 and the resistance (R1=R5) of the resistor R1. Thus, the input impedance Zin is constant independently of frequencies, no reflection of the input signal is caused and the VSWR is substantially brought into '1'.
