摘要： A method of controlling diaphragm driving in an electronic still camera, wherein a diaphragm is controlled such that an exposure value of a subject on an image forming screen can become a proper exposure value, and a device therefore. In this control of diaphragm driving, the photometric values obtained from every times of photometry are determined to be higher or lower than the proper exposure value. When the photometric values are determined to be higher than the proper exposure value continuously given times, the diaphragm is closed until the photometric values are determined to be lower than the proper exposure value. When the photometric values are determined to be lower than the proper exposure value continuously the given times, the diaphragm is opened until the photometric values are determined to be higher than the proper exposure value.

摘要： All access points are operated synchronously, and monitor the beacon to mate with the hopping frequency of the neighboring access point. Accordingly, the station can grasp the up-to-date radio situation of the neighboring access point to be entered subsequently, and constructs the information as the database. As a result, when the beacon quality of the current subscription (connected) access point is reduced lower than the threshold value, the hopping channel and the hopping pattern are fitted to the neighboring access point having the best communication environment by referring the database, and then the subscription operation is applied directly.

摘要： A multi-hole injector directly injects fuel into a combustion chamber. Intake air is introduced into the combustion chamber through intake ports to provide tumble flow in the combustion chamber. A cavity is formed in a part of the top surface of a piston which is eccentric to the exhaust side. In the intake stroke, fuel injection ends in a downstroke of a piston. When the crank angle is 100 degrees after the top dead center in the intake stroke at which the fuel injection ends, a most downward lower spray collides with a part of the top surface of the piston which ranges on the intake side from the edge on the exhaust side of the cavity. A most upward upper spray does not come into contact with a spark plug. Thus, the fuel injection can enhance the tumble flow to promote homogeneous dispersion of fuel-air mixture in the combustion chamber.

摘要： A semiconductor substrate is coated with an insulation mask. A window is cut in the mask using photolithography leaving stress risers at locations defining the length of a laser cavity. A plurality of layers of semiconductor film are selectively grown over the exposed substrate to form a pin diode and necessary impurities are injected. An intrinsic layer of the film forms a laser excitation layer and emits laser beams in response to excitation. Following heat treatment, the device is cooled rapidly, causing stress in the areas where the stress risers from the mask join the semiconductor film. By the time the device reaches room temperature, the semiconductor film is split and separated by cleavage planes. Alignment of the semiconductor laser device output beams is produced by anisotropic etching of the cleavage planes to form 45.degree. mirror planes. Conventional photolithographic techniques permit formation of the laser resonator with an accuracy on the order of submicrons.
