Abstract: A lens unit being connected to the camera unit and being selectively set either in a mode in which control is effected according to a control signal from the lens unit or in a mode in which control is effected according to a control signal from the camera unit, wherein when a signal for setting of mode is not input from the camera unit with a lapse of a predetermined time or more after power on of the power supply, a setting circuit sets the mode in which control is effected according to the control signal from the lens unit.

Abstract: There is disclosed a command-answer type serial communication device between TV lens and TV camera, or between TV lens and accessory. In the command-answer type serial communication, answer data is transferred in response to a command in ordinary communication, but data to be processed at high speed on the side of a device having transferred the command is transmitted to a camera from a lens even if no command is transmitted, so that high-speed communication can be performed.

Abstract: A control apparatus for an optical device including a lens system having a moving lens and a camera to which the lens system is attached, includes a first control signal output unit including a first operation member and outputting a first control signal to control a movement of the moving lens in accordance with an operation of the first operation member, where the first control signal output unit is electrically connected to the lens system, and a second control signal output unit including a second operation member and outputting a second control signal to control a movement of the moving lens in accordance with an operation of the second operation member, where the second control signal output unit is electrically connected to the camera, and the second control signal is output to the lens system through the camera.

Abstract: When a lens unit with a digital serial interface was connected to a camera unit without the interface, there arose the problem that setting was disabled of a mode of the lens unit from the side of the camera unit. The present invention provides a lens unit, solving the above problem, the lens unit being connected to the camera unit and being selectively set either in a mode in which control is effected according to a control signal from the lens unit or in a mode in which control is effected according to a control signal from the camera unit, wherein when a signal for setting of mode is not input from the camera unit with a lapse of a predetermined time or more after on of power supply, a setting circuit sets the mode in which control is effected according to the control signal from the lens unit.

Abstract: An image pickup apparatus drives a moving lens in accordance with first and second command signals. The apparatus includes a first detection means for detecting the first command signal, a second detection means for detecting the second command signal, a selection means for selecting one of the first and second command signals on the basis of the output signals from the first and second detection means, and a driving means for driving the moving lens on the basis of the command signal selected by the selection means.

Abstract: This invention relates to a driving device for a vibration type motor. According to this invention, maximum speed data of the motor is obtained in accordance with the temperature, and the speed is controlled using the data as an upper limit, thereby properly driving the vibration type motor.

Abstract: Premix preparation for ice foods comprising, as essential components, (1) an unsaturated fatty acid-free oil, (2) a glycerin fatty acid ester and (3) a mixture of pectin and pregelatinized starch. The premix preparation being capable of stably maintaining an emulsifized state of the preparation, providing a product capable of preserving for a long period, avoiding a deterioration of the taste under the sterilization at a high temperature, and enabling to easily make a shake at home.

Abstract: The present invention relates to a preservation method and preservation apparatus which are suitable for preserving perishable goods for a long period of time. A method of the present invention is characterized by removing from the refrigerating chamber such harmful aging substances as ethylene or volatile base nitrogen triethylamine which are released from the perishable goods being preserved in a refrigerating chamber and which cause additional maturation and aging. In order to realize this method, an apparatus of the present invention is characterized by comprising adsorption materials which have adsorptivity to adsorb these harmful aging substances and are disposed in the refrigerating chamber for preserving the perishable goods.
