摘要： An exhaust gas purifying system for internal combustion engines includes a three-way catalyst disposed in the exhaust system of the engine, and secondary air is supplied to the exhaust system through an air control valve under the control of an air-fuel ratio control circuit. The air-fuel ratio control circuit produces a control signal which increases or decreases stepwisely at every reception of a clock signal depending on whether the air-fuel ratio in the exhaust system is above or below a stoichiometric air-fuel ratio. The air control valve is of the proportional electromagnetic type and controls the secondary air passing therethrough in proportion to the control signal.

摘要： A field watch apparatus uses a storage unit to store detection data of a detected obstacle from an obstacle sensor that detects objects under control of a control unit, and the detection data accumulated in the storage unit over time is used to display a mark on a captured image that is captured by a camera and shown on a screen of a display unit. The mark size and other attributes of the mark in the image are controlled in a manner that enables a view to easily recognize an old mark from a new one, thereby providing an intuitive recognition of the obstacle movement in a certain direction in the captured image, when the mark is superposed in the captured image for multiple times based on the accumulated detection data in the storage unit.

摘要： An obstacle detection apparatus includes first and second ultrasonic sensors, a control part, and a warning device for warning in accordance with a distance between at least one of the ultrasonic sensors and an obstacle. The control part sets the first ultrasonic sensor to a transmitting and receiving mode while setting the second ultrasonic sensor to a receiving mode, and then sets the first ultrasonic sensor to the receiving mode while setting the second ultrasonic sensor to the transmitting and receiving mode. Each of the ultrasonic sensors has a reception sensitivity to a reflected wave reflected by the obstacle. Each of the ultrasonic sensors includes a reception sensitivity control portion configured to increase the reception sensitivity when the receiving mode is set compared with when the transmitting and receiving mode is set.

摘要： An obstacle detection device has an ultrasonic sensor fixed to a first side of a mount member. The ultrasonic sensor sends/receives ultrasonic wave toward/from a second side of the mount member, which is opposite to the first side thereof. At least one of a mounting surface of the ultrasonic sensor and a mounting surface of the mount member has a protrusion, which protrudes therefrom so that an end surface of the protrusion contacts the other of the mounting surfaces. The mounting surfaces of the mount member and the ultrasonic sensor face each other. The end surface of the protrusion and the mounting surface of the ultrasonic sensor are different from each other in at least one of shape and area thereof.

摘要： A display panel driving system, constituted in such a manner that the occurrence of a display irregularity on the display panel can be suppressed without regard to the characteristics or the driving condition of the display panel, is disclosed. An up-counter counts the number of the picture elements which emit light when the EL display panel is horizontally scanned, and the counting result thus obtained is outputted as an addressing signal to an EEPROM. Stored in the EEPROM are data maps MAP, MAP in which pulse width data are written at a plurality of addresses corresponding to the counting ranges of the up-counter. A signal generation means outputs a blank signal BLK which determines the pulse width of a data voltage on the basis of the pulse width data addressed by the up-counter.

摘要： An electroluminescent display panel having a matrix electrode structure composed of scanning electrodes and data electrodes is driven by supplying scanning voltages either alternately or simultaneously from both sides thereof in order to eliminate uneven luminance along a longitudinal direction of the scanning electrodes. Two scanning electrode driving circuits, each connected to each side of the scanning electrodes, may be used. Since an overall luminance of the electroluminescent display panel is a summation of the luminance obtained by scanning the scanning electrodes from one side and the other side, the luminance along the scanning electrodes becomes uniform by scanning from both sides. The data electrodes may be driven from both sides thereof in the same manner as in the scanning electrodes.
