An apparatus and method for controlling a light source that is used during operation of an imaging device (e.g., a camera) and, in particular, during operation of a camera feature/subsystem such as an AF subsystem, a red-eye reduction subsystem, a self-timer subsystem, etc. The apparatus and method include and involve a light source which is configured to emit light in relation to the operation of a subsystem of an imaging device, and a light source control unit which is configured to control an amount of light emitted by the light source based on a preset operating parameter (e.g., a user-selectable camera setting). The apparatus and method may be included within an imaging device such as a camera or in a peripheral (e.g., a flash unit, etc.) configured to operate with such a camera.

A pneumatic tire comprising a tire tread wherein a foamed rubber layer is provided at least in the portion substantially contacting with a road surface, and wherein said foamed rubber layer, which has closed cells, has an expansion ratio of about 2% to about 50%, and the solid rubber phase in said foamed rubber layer contains, in an amount of about 0.5 to about 5 parts by weight per 100 parts by weight of the rubber component, a vulcanization accelerator represented by one of the following general formula: ##STR1## wherein R.sup.1 and R.sup.2 each independently represents an atom or a group selected from a group consisting of a hydrogen atom, alkyl groups, and aryl groups, excluding a case in which each of R.sup.1 and R.sup.2 simultaneously represents a hydrogen atom. The pneumatic tire which is used as an excellent studless tire suppresses deterioration in performance on ice or snow in the final period of tire use compared to the performance in the initial period of tire use.

摘要:
An electronic flash apparatus uses a voltage-controlled switching device, such as an insulated gate bipolar transistor, for controlling the start and termination of flash emission from a flash discharge tube. A peak voltage of an oscillation generated in a resonant circuit, produced in response to a flash emission start command, is clamped by a clamping circuit and is used to turn on the voltage-controlled switching device. Another resonant circuit may be used for doubling the voltage between the anode and cathode of the flash discharge tube when the flash discharge tube is triggered.

An electronic flash device is detachably mountable on a camera and capable of data communication with said camera. The electronic flash device comprises a display unit for automatically setting photographing information upon receiving relevant data from the camera or manually setting photographing information. The display unit is set in a first display state when the device is mounted on a camera capable of data communication and data are transmitted therefrom, or is set in a different display unit when the device is mounted on a camera incapable of data communication and no data are transmitted therefrom.

An electronic flash apparatus for flash photographing comprises flash discharge means, means for supplying a voltage to the flash discharge means, first light emission control means comprising first trigger means for triggering the flash discharge means to cause a discharge therein, for the purpose of the flash photographing and second light emission control means. The second light emission control means comprises oscillator means for generating periodic output signals, second trigger means for periodically triggering the flash discharge means in response to the periodic output signals thereby periodically initiating the discharge in the flash discharge means, detecting mean for generating an output signal upon detection of the initiation of the discharge in the flash discharge means and means for terminating the discharge in the flash discharge means in response to the output signal of the detecting means.The electronic flash apparatus further comprises means for selecting either a first mode in which the flash discharge means is controlled by the first light emission control means or a second mode in which the flash discharge means is controlled by the second light emission control means, and means for driving the light emission control means in a manner different from the flash photographing.
摘要:
The present invention aims to solve the conventional problems by providing a peptide compound, in which when administered to a patient of immunologic disease, cardiac hypertrophy or a disease caused by NFAT activation, the period from administration to actual exhibition of effectiveness is short and there are no side effects or antigenicity. Specifically, the present invention relates to a membrane permeable NFAT inhibitory peptide comprising several consecutive arginines and a NFAT-activity inhibitory peptide sequence; a NFAT activation inhibitory agent comprising the peptide; and a immunosuppressive agent and cardiac hypertrophy suppressive agent, comprising the peptide compound as the active ingredient.
