A dual-power-supply system uses both a fuel cell and a chargeable secondary battery. A differential voltage adding unit adds a differential voltage between the voltage of the fuel cell and a necessary target output voltage to the voltage of the fuel cell by using the secondary battery, thereby obtaining an output voltage of the dual-power-supply system. A control unit detects the output voltage, and controls the differential voltage adding unit such that the output voltage is equal to the target output voltage.

This invention relates to an applicator for applying coating medium, in particular coating medium in several layers onto a running web surface. The applicator includes several curtain heads, which are arranged at random distances apart and from which the coating media or colors are dispensed downward, and an inclined guide face which—as the result of lamination of the coating media or colors dispensed one after the other from each of the several curtain heads along the incline in order to form the several medium or color layers and, in addition, to form a color curtain from a curtain guide part pointing downwards—moves the color layers at the end of the part of the incline onto the web surface.

A microcomputer (.mu.COM) in a camera causes an EEPROM in a memory unit to store data on each picture taken. The photographic data stored in the EEPROM is read by the .mu.COM and displayed on a display unit. According to the operation of an UP SW or a DOWN SW, the .mu.COM updates the contents stored in the EEPROM now being displayed. The photographic data stored in the EEPROM is written in a first magnetic track on the film by a first magnetic head arranged in a magnetic information control circuit, at the time of the rewinding of the film. In addition, when a film with which photography is already finished is loaded in the camera, the .mu.COM, while advancing the film, causes the first magnetic head to reproduce the data written in the first magnetic track on the film and stores the reproduced data in the EEPROM.

A semiconductor device including a semiconductor substrate; a metal wiring layer formed on the semiconductor substrate; a first insulation layer formed on the metal wiring layer, the first insulation layer being formed by a tensile stress insulation layer having a contracting characteristic relative to the substrate; and a second insulation layer formed on the first insulation layer, the second insulation layer being formed by a compressive stress insulation layer having an expanding characteristic relative to the substrate. The tensile stress insulation layer is produced by thermal chemical vapor deposition or plasma assisted chemical vapor deposition which is performed in a discharge frequency range higher than 2 megahertz; and the compressive stress insulation layer is produced by plasma assisted chemical vapor deposition which is performed in a discharge frequency range lower than 2 megahertz.
摘要:
An optical image of an object is incident on a light-receiving unit of a two-dimensional matrix through a photographing lens. An output from the light-receiving unit is input to a first arithmetic logic unit to calculate an actual object brightness value in consideration of an aperture value of an aperture. An output from the first arithmetic logic unit is input to a multiplexer and a neural network. The neural network determines a main part of the object from brightness value pattern as a set of brightness values of the photoelectric transducer elements and outputs a position signal representing the main part. A multiplexer selectively passes only brightness values of the photoelectric transducer elements corresponding to the main part of the object from the outputs from the first arithmetic logic unit. An output from the multiplexer is supplied to a second arithmetic logic unit, and the second arithmetic logic unit calculates an APEX calculation on the basis of a speed value, an aperture value, a time value, and a mode signal representing a shutter or aperture priority operation, thereby determining a shutter speed or an f-number.

An electric power conversion device comprises a conversion circuit having bi-directionally switchable plural pairs of switching elements connected to respective phases and converting an inputted AC power into an AC electric power. A first switching time is calculated using detected voltages detected by voltage sensors and an output command value. A second switching time is calculated in a form of a time which is a subtraction of the first switching time from a half period of a carrier and, using this time, control signals to switch on and off of the switching elements are generated.

An electric power conversion device comprises a conversion circuit having bi-directionally switchable plural pairs of switching elements connected to respective phases and converting an inputted AC power into an AC electric power. A first switching time is calculated using detected voltages detected by voltage sensors and an output command value. A second switching time is calculated using a carrier and the calculated first switching time. The second switching time is such that, in one period of the alternating current electric power outputted from the conversion circuit, the second switching time included in a first half period of the one period is equal to the second switching time included in a second half period of the one period.
