摘要:
A video camera includes a solid-state image sensing device, and an electric signal from the image sensing device is converted by a camera circuit into a video signal which is further converted into a digital video signal by an A/D converter. The digital video signal is stored in a field memory sequentially field by field under control of a memory control circuit. A motion detecting circuit which receives the digital video signal calculates correlative values for each of a plurality of blocks constituting a whole screen according to a representative point matching method. A microcomputer calculates motion vectors of respective blocks on the basis of correlative value data from the motion detecting circuit and an average motion vector thereof, and calculates "increase", "passing degree" and "variation". The microcomputer further evaluates a reliability of each of the blocks according to a fuzzy inference by utilizing the increase, passing degree and variation as parameters. The memory control circuit determines correction amount for a picture stabilization on the basis of the reliability and the average motion vector.

A controlling device for controlling the transmission ratio of a non-stage transmission in a vehicle. The transmission ratio is controlled according to a forecast output power of the vehicle. The output power is forecast based on an operating condition of the vehicle, such as atmospheric pressure. The control considers various operating parameters. A comparison of a predetermined ratio of increase of engine speed or throttle opening with actual ratios of increase of engine speed or throttle opening may be made in controlling the transmission ratio. An uneven road surface is detected and a transmission ratio of the transmission is controlled accordingly to substantially eliminate hunting. An engine speed is controlled so that the engine speed may not exceed a predetermined rotational speed when the transmission gear ratio is fixed. A target engine speed or target transmission ratio is corrected in response to an output signal of a comparison device which compares an actual vehicle velocity with a set vehicle velocity during automatic fixed vehicle velocity running.

A refrigerator cabinet having an outer box comprised of a top wall and both side walls which are formed by bending one steel sheet that has been previously coated with paint, wherein one of front flanges adjacent to each other at the upper corner or corners of the outer box at least on the unsupported side of the door is bent along an inclined reference line extending from the corner to form a bent portion while at the same time forming a predetermined space on its rear side, the other of the front flanges is bent along said inclined reference line to form a stepped portion, and said bent portion is laid on top of the stepped portion, whereby the front surfaces of the front flanges adjacent to each other at said corner or corners are substantially flush with each other to come into sealing engagement with a door seal strip formed on a door.

In an air-fuel ratio control system for an internal combustion engine, the basic fuel injection amount computed from engine parameters such as engine speed and intake air flow is corrected by using map having air-fuel ratio compensation data stored battery back-up in accordance with the engine parameters. The compensation data is read out of the map in accordance with the parameters at the time of detection of the stable combustion state of the engine. When an output of an oxygen sensor is on lean side, a predetermined amount is added to the data thus read, while when the output of the oxygen sensor is on rich side, a predetermined amount is subtracted from the data thus read, thereby renewing the stored value.
摘要:
A closed loop mixture control system for internal combustion engines is responsive to a signal derived from an exhaust gas sensor. The sensor signal is time-integrated in a direction depending on the level of the gas sensor output to derive a first mixture corrective setting of the control system. Second corrective settings or learning data are established for the control system in correspondence with the amount of air supplied to the engine. Each of the latter settings is varied as a function of time in a direction depending on the value of the time-varying first corrective setting relative to a reference so that the second settings are automatically updated to meet varying engine performance such as aging. One of the second corrective settings is selected in response to the detected quantity of the supplied air and multiplied by the first corrective setting to correct the basic mixture control setting of the system toward an optimum value. All of the second corrective settings are reset to appropriate values, for example, "1" at the instant the engine is started if an average value of the second settings is greater than a predetermined value to compensate for different fuel vaporizations.

An AC/DC power supply device for operating a refrigerator compressor by switching over the AC operation mode in which the compressor is operated from AC power source and the DC operation mode in which the compressor is operated from DC power source through an inverter circuit, wherein a thermostat is constructed so as to be connected to a circuit for supplying DC voltage to the inverter circuit in the DC operation mode, and a switching section is constructed so that high potential points including the potential of the AC power source and low potential points including the potential of the DC power source do not face each other in close vicinity to prevent the AC power voltage from being unwantedly applied to the low voltage side.

A heater includes a heating element, a pair of lead wires each connected to an end of the heating element, and an insulating base body in which the heating element and the pair of lead wires are embedded. The insulating base body contains a plurality of metal particles around the heating element, the metal particles being separated from the heating element. The plurality of metal particles and the heating element comprise an elliptical cross-section comprising a same major axis direction. With such a structure, when the heater is rapidly cooled to cause a crack on the surface of the insulating base body, the crack develops along the major axis direction of the metal particles and therefore rarely reaches the heating element. This resists breakage of the heating element.

An execution log generation apparatus generates an execution log upon receiving, for each job operation, job operation data indicating content of a job operation performed in a job procedure from a job processing apparatus that performs job processes through job procedures. The execution log generation apparatus includes a definition file holding unit that holds a definition file in which job operations performed in the job procedures are defined along a flow of the job processes and the job procedures, and in which output items to be output as execution logs for the each job operation are listed in a common format; and an execution log output unit that selects, from the definition file, an output item corresponding to a job operation contained in the job operation data, and outputs, as an execution log, the same output item as the selected output item from the job operation data.
