Title: Method and device for detecting multiframe synchronism
Inventor: MURAKAMI YOSHIAKI
IPC: H04L7/08
Filed: 1998-10-14
Abstract: PROBLEM TO BE SOLVED: To detect the synchronism of multiframe speedily without requiring a large capacity memory. SOLUTION: When HDLC pattern data are detected twice by a specified pattern comparing part 26 at the same time interval as the transmission cycle of frames, the bit of the next bit clock timing is decided as being the frame bit of each frame. Then, rather than having the bit information of multiframe as a whole fetched into a memory circuit 32 only the bit information which is decided as being the frame bit is fetched and based on the fetched contents, the timing at the head of multiframe is detected. Hence, the storage capacity of a storage device for storing bit stream signals can be reduced and the circuit scale of the device can be miniaturized.

Title: Synchronous motor control method and engine fuel controller including that control method
Inventor: ASANO SEIJI
IPC: F02D9/02
Filed: 1995-11-10
Abstract: PROBLEM TO BE SOLVED: To attain a finer rotational angle resolution of rotor as compared with a case where a motor is driven only through two-phase excitation by switching the driving frequency when the motor is driven through combination of two-phase excitation and when the motor is driven through combination of two-phase and single-phase excitation. SOLUTION: A shaft 302 is inserted into a synchronous motor 301 and telescoped according to the rotation thus opening and closing a valve 303. The synchronous motor 301 is fed with a motor drive signal in synchronism with the driving period and the rotor is shifted to a stop position corresponding to each drive pattern. The motor is driven with two-phase excitation until a slice level spaced apart specifically from a target position is reached and then driven with 1-2 phase excitation at lower rate than the driving period of two-phase excitation until a target value is reached. Since the motor is driven with 1-2 phase excitation when the target value is approached, a finer rotational angle resolution of rotor can be attained as compared with a case where the motor is driven only through two-phase excitation.

Abstract: PURPOSE:To synchronize with read NRZ data and to easily obtain a clock signal having the duty ratio of 1/2 by composing of a peak position detecting circuit, a data separator, a 1-7/NRZ converter, a delaying circuit and an OR gate. CONSTITUTION:A peak position detecting circuit 101 inputs a data reading signal, a pulse is generated by the peak position of the waveform, and a data separator 102 outputs a 1-7 data signal and a 3F (three-fold frequency) clock signal from a peak data pulse signal. Next, a 1-7/NRZ converter 103 executes a logical conversion from a 1-7RLL to an NRZ, outputs it, and simultaneously, outputs a 1F clock signal having one-fold synchronizing frequency to an NRZ data signal. A delaying circuit 104 gives a fixed time delay to the 1F clock signal, and outputs it through an OR gate 105 in making it into a normalizing clock signal.

Title: Image detecting method
Inventor: HORI HISAMITSU
IPC: G03B27/34
Filed: 1987-11-24
Abstract: PURPOSE:To decide whether an image exists or not in a short time and with high accuracy by comparing a frequency value of a histogram for showing the number of picture elements to an output signal of an image sensor, with a prescribed value, and also, comparing the number of times of a polarity inversion obtained by binarizing the output signal of the image sensor, with a prescribed value. CONSTITUTION:When an expanse in the axis-of-abscissa direction of a histogram derived from an image signal of a narrow area, namely, the overall length L1 in the axis-of-abscissa direction in which the histogram exceeds a set value exceeds a set value, it is decided that an image exists, and by using this area. Also, when the overall length L becomes below the set value and it is decided that no image exists, this histogram derives binarization levels (a), (b) by using a histogram whose crest is high and whose width is narrow. Thereafter, while changing a focus zone, an output signal of a line sensor is binarized in a real time, and with respect to the focus zone in which the number of times of its polarity inversion exceeds a prescribed value, it is decided that an image exists. In such a way, whether the image exists or not can be decided in a short time and with high accuracy.

Abstract: PURPOSE:To prevent overcharge by interrupting charging operation before a time, required for finishing charging operation of battery, is reached and interrupting the charging operation if the battery voltage is lower than a second reference voltage for judging abnormality which is lower than a first reference voltage for judging completion of charging operation. CONSTITUTION:Charging current is temporarily interrupted at a stage fairly earlier than a time when a normal battery finishes charging operation. Battery voltage is detected upon elapse of settling time of electrochemical transient phonemenon associated with interruption of charging operation. The battery voltage is then compared with a second reference voltage for judging abnormality which is lower than a first reference voltage of 15V. If the battery voltage is lower, the battery is judged to be abnormal and charging operation is interrupted.
