Title: Air-fuel ratio controller of engine
Inventor: MITSUNAGA SEISUKE
IPC: F02D41/04
Filed: 1993-10-29
Abstract: PURPOSE:To prevent variation or hunting of an air-fuel ratio while improving emission performance at the time of feedback-controlling the air-fuel ratio in a lean burn range. CONSTITUTION:An air-fuel is feedback-controlled by a control unit 13 in a specified range, in an engine CE. Variation or hunting of the air-fuel ratio is prevented by making lean side dead zone width a comparatively large value at the time of feedback-control in the lean burn range, and then torque variation can be prevented. On the other hand, the air-fuel ratio can be prevented from staying on the rich side for a long period by making the rich side dead zone width a comparatively small value, and then an NOx generation quantity is decreased and emission performance is improved. The dead zone width becomes further less value outside the lean burn range, and then the air-fuel ratio is prevented from staying for a long time in the range where the NOx generation quantity is large, and thereby the emission performance is improved.

Title: Frequency multiplier circuit
Inventor: YANO NOBUMITSU
IPC: H03K5/00
Filed: 1985-12-02
Abstract: PURPOSE:To uniform the duty of an output pulse by connecting delay circuits having an inverting function in cascade connection of plural odd stages. CONSTITUTION:A delay circuit 11 consists of a buffer 8 controlling the charge/ discharge of an integration device 9 and a buffer 10 waveform-shaping the output of the integration device 9 and inverting the waveform. A delay circuit 15 consists of the same constitution as the circuit 11. An output signal 2B delayed by a time t1 from the leading of the input signal 2A and by a time t2 from the trailing is obtained from the delay circuit 11. The signal 2B passed through a delay circuit 15 and retarded by the time t2 from the trailing and by he time t1 from the leading and becomes an output signal 2C. The signal 2C is inputted to a multiplier 16 as a signal delayed by a time (t1+t2) both from the leading and the trailing of the input signal 2A and multiplied with the input signal 2A. Thus, even when the delay time of the delay circuits has variance, a pulse signal having a uniform duty is obtained.

IPC: F16K31/04
Filed: 1994-11-07
Abstract: PURPOSE: To reduce noises accompanying reset process while improving the life of a mechanical limiter by providing the mechanical limiter fully opened in a flow regulating valve to forcibly stop the shift of a valve element at the fully opened limiter position and carrying out the reset process when the number of times of hot water supply reaches a required reference value. CONSTITUTION: When a power source is turned on, first a valve element of a flow regulating valve 1 is moved to a zero point position (fully closed limiter position) to wait for the requisition of hot water supply. When hot water is required, a desired arriving position of the valve element is figured out to drive a stepping motor 3. Next, when the hot water supply process is completed, the count number K of an internal counter in a controller 19 is set to K+1. Whether or not the count number K reaches a predetermined value is judged. In the case of YES, when a time elapses since the hot water supply is stopped exceeds a reference value and a requirement for stopping water flow to a water supply path is established, the internal counter is reset to carry out the reset process, i.e., the stepping motor 3 is driven to shift the valve element to the zero point position.

Title: Ferroelectric liquid crystal controller
Inventor: NEZU YUSHI
IPC: G09G3/36
Filed: 1988-10-31
Abstract: PURPOSE:To execute refreshing at specified intervals and to eliminate the disturbance of a screen by clocking the partial writing to a memory for display by a timer and interrupting the writing upon lapse of the prescribed time, then executing only the refresh operation. CONSTITUTION:A flag 3 is usually checked via a sequencer 4 and the refreshing of an FLC panel 6 is repeated by a prescribed procedure. Clocking by the timer 5 is started when a plotter 1 executes the writing to the memory (VRAM) 2 to display. The sequencer interrupts the partial writing operation and executes the continuation of the previous partial writing after executing the refreshing upon lapse of the prescribed time. Since the refreshing operation of the FLC display device is executed always at the specified period, the generation of flickers and the disturbance in the screen arising from the failure in the execution of the partial writing and the decrease of the contrast in the position on the screen are suppressed.

Title: Measuring method for linearity of saw-tooth wave
Inventor: KUSAKABE HIDEO
IPC: G01R29/00
Filed: 1985-12-06
Abstract: PURPOSE:To measure the linearity of a saw-tooth wave with high accuracy by using a saw-tooth wave which is not affected in the turn-off operation of the analog switch of a Miller integrator as a reference saw-tooth wave. CONSTITUTION:A reference saw-tooth wave generator 10 uses a generator having nearly the same characteristics with a saw-tooth wave generator 11 to be measured and the center part of the saw-tooth wave having stable characteristics (good linearity) is used. Part of the output of the oscillator 11 where the analog switch SW2 of the Miller integrator is turned off (i.e. starting part of saw-tooth wave) is compared with the linear part of the oscillator 10, so that the linearity of the output of the generator 11 is detected by a distortion detector 13. The output of an adder 12 is amplitude-limited except within a distortion detection range by an amplitude limiting circuit incorporated in the detector 13 and the DC part within the distortion detection range is amplitude faithfully, so high-precision measurement is performed.
