Title: Motor speed controlling device
Inventor: KOBAYASHI NORIO
IPC: H04Q3/545
Filed: 1992-06-18
Abstract: A motor speed controlling device controls the rotational speed of a motor by feeding back an actual rotational speed, for example detected by a photocoupler. An encoder disk formed with equi-pitch slits in the periphery thereof is attached to the drive shaft of the motor, and the photocoupler is provided in association with the encoder disk. A CPU computes (S100) ON duration Ton and OFF duration Toff of pulse trains produced from the photocoupler when the motor is rotating at a constant speed. If the ON duration Ton and OFF duration Toff are unequal, ON correction and OFF correction factors  alpha , beta  are computed (S120) based on the measured ON and OFF durations, whereas if the ON duration and the OFF duration are equal to each other, the ON and OFF correction factors are set to one (S130). The CPU corrects the ON and OFF durations Ton and Toff based on the ON and OFF correction factors. The pulse trains nominally have a 50:50 duty ratio but this may vary due to, for example, aging of the photocoupler. The device may be used in an electronic typewriter. <IMAGE>

Title: Time-varying image signal coding/decoding system
Inventor: KOGA TOSHIO
IPC: H04N19/65
Filed: 1992-08-28
Abstract: Video signals are transform coded 1, and the transform coefficients subjected to predictive encoding in loop 2,3,6,7,8 before transmission via code transform circuit 4. When refreshing of the frame memory 16 of the decoder is to occur, refreshing takes place on a group-by-group basis, each group consisting of a plurality of transform coefficients of similar sequency. Refreshing of frame memory 16 is carried out by setting switches SW1 and SW2 to the output of the second quantizer 7. During normal operation of the system switch SW1 connects quantizer 3 to the code transform circuit, and switch SW2 to the output of adder 6 when the loop functions predictively. Motion compensation may be provided (figure 6), and the transform coder 1 may be placed within the predictive loop (figure 7). <IMAGE>

Title: Door lock device with one-motion door opening mechanism
Inventor: HAMAGUCHI OSAMU
IPC: E05B65/32
Filed: 1993-08-23
Abstract: A door lock device has an one-motion door opening mechanism. The door lock device comprises a latch mechanism consisting of a latch 34 and a pawl 51 preventing the latch from reverse-rotating, an outer opening lever 14, a lock lever 41, a link 35 operatively placed between the outer opening lever 14 and the lock lever (41), an inner opening lever 19 connected to the inside opening handle (73) of the vehicle door. When the link 35 it is at the locked condition and the inside opening handle (73) is operated to open the door, the pawl 51 is disengaged from the latch 34 and the link 35 is pressed by a pressing piece 53 to displace it to the unlocked position. When the inside opening handle (73) is excessively rotated the link 35 will not be excessively displaced, due to lost motion between the link 35 and the pressing peace 53. Therefore it is not necessary to provide a space for excessive link movement, enabling the lock to be installed in a narrower space thus making criminal manipulation of the lock less likely. <IMAGE>

IPC: H03L7/197
Filed: 1995-04-26
Abstract: A frequency synthesizer includes a voltage-controlled oscillator 5, frequency dividing circuits 14, 15, a signal source 1, phase comparing circuits 11, 12, an adding circuit 13, a converting circuit 4 and a control circuit 16. The frequency dividing circuits divide an output supplied thereto from the voltage-controlled oscillator by with frequency-dividing ratios of 1/N and 1/(N+1) where N is an arbitrary integer. The signal source outputs a reference frequency signal. The phase comparing circuits phase-compare a signal divided by the N supplied thereto from the frequency dividing circuit and a signal divided by the (N+1) supplied thereto from the frequency dividing circuit and the reference frequency signal from the signal source. The adding circuit adds a signal which results from phase-comparing the reference frequency signal output from the phase comparing circuit and the signal divided by N and a signal which results from phase-comparing the reference frequency signal output from the phase comparing circuit and the signal divided by (N+1). The converting circuit converts an output from the adding circuit to a DC signal and supplies the same to the voltage-controlled oscillator. The control circuit controls frequency-dividing ratios of the frequency dividing circuits. The control circuit cyclically changes the frequency-dividing ratios of the frequency dividing circuits to 1/N or 1/(N+1). <IMAGE>
