Title: Successive approximation analog-digital converter
Inventor: HIDARI HIROBUMI
IPC: H03M1/48
Filed: 1987-12-22
Abstract: PURPOSE:To obtain an analog/digital converter with less errors and capable of operating at a high speed by providing a means applying increase/decrease control to a frequency of a clock signal based on the absolute value of a difference between an input signal and an output of D/A conversion. CONSTITUTION:An output of an up-down counter(Cud) 21 is supplied to an output buffer 10 and a D/A converter 3 and an analog output of the converter 3 is fed to a differential amplifier 7 and a comparator 4. The output of a differential amplifier 7 is converted into a positive signal by an absolute value circuit 8 and fed to a voltage variable frequency oscillator(VCO) 11. On the other hand, the output of the comparator 4 is supplied to a control gate (CG) 15 and the clock outputted from the VCO 11 increments/decrements the Cud 21 via the CG 15. In such a case, a signal proportional to a difference between the analog quantity from the value of the Cud 21 and the input signal 5 is generated in a clock control line 17 and the VCO 11 generates a signal of the frequency proportional to the voltage. The signal is fed to the Cud 21 via the CG 15 to decide the increasing/decreasing direction of the Cud 21.

Title: Misfire detector of internal combustion engine
Inventor: MATSUMOTO TAKUYA
IPC: F02P17/12
Filed: 1995-12-13
Abstract: PROBLEM TO BE SOLVED: To accurately detect misfires with a simple structure. SOLUTION: When an engine revolution number Ne(n) exceeds a switching determination revolution number NeA, an ECU 30 calculates the angular acceleration Dω (n) of a crankshaft 23 based on a timing for moving away of a rear end from a sensor main body 26 (that is, BTDC 5 deg.) instead of a timing for entering of each vane tip formed in a rotor plate 25 into the sensor main body 26 (that is, BTDC 75 deg.). Then, the ECU 30 calculates an average angular acceleration Dave (n) corresponding to each cylinder from angular acceleration Dω (n) in a misfire determining region, determines whether this is lower than a misfire determination threshold value Dω A or not and if this determination is Yes, a misfire alarm lamp 31 is lit or the like in a misfire processing subroutine and then the process returns to START and control is repeated.

IPC: B41J2/30
Filed: 1992-12-07
Abstract: PURPOSE:To convert stored energy into power not by converting a surge voltage generated when an inductive load switching of a boosting circuit is turned off into heat but by converting the surge voltage into power so as to improve the switching speed of the inductive load drive circuit. CONSTITUTION:The energy stored in an inductive load is stored in a smoothing capacitor 8 through a rectifier diode 5 when a drive circuit 3 is turned off, and when the voltage across the capacitor is higher than an input voltage VIN, the diode 5 is turned off. A lower limit voltage higher than the input voltage VIN and the upper limit voltage of a P-channel MOSFET 6 being an electric switch and a comparator 9 are set within a load drive voltage. Then a hysteresis is provided in the voltage range and no voltage is given to a load up to the upper limit voltage and when the upper limit voltage is reached, the voltage application is not stopped till the lower limit voltage is reached. Thus, the energy stored in the inductive load is converted into power by using a smoothing capacitor 8 of other system and the supply of power to a load is attained without requiring a new power supply.
