摘要:
An engine blower includes a centrifugal blower having a volute case in which a fan is accommodated; an engine attached to the centrifugal blower for driving the fan; a carburetor mounted to the engine via an insulator; and a lead wire that establishes conduction between the engine and the carburetor. The electrical potential difference between the engine and the carburetor can be eliminated, which prevents electrostatic discharge between the engine and the carburetor even when static electricity is built up in a volute case or a ventilation tube. Accordingly, ignition timing can be prevented from shifting due to an influence on an electrical circuit by the discharge within an ignition unit.

A CCD image sensor 14 uses sufficiently more pixels than those in an output image. A pixel number conversion block applies pixel number reduction conversion to an image pickup signal from the CCD image sensor 14. This signal is output as a monitor output or motion-picture recording signal via a terminal 43. Converting the multi-pixel image signal to a reduced image can provide an output image with improved sharpness.

There is here disclosed a water treatment apparatus in which a membrane separation device is disposed above a gas diffuser device arranged in a treating tank, wherein diameters of gas discharge holes formed in the gas diffuser device are within a range of 1 to 10 mm, and a relational expression of 20
摘要:
A method for cleaning separating membranes uses a uniquely formulated detergent. The detergent includes a percarbonate-containing, material, existing in the condition in which hydrogen peroxide is adducted in carbonate and is desirably an alkali metal salt. The percarbonate decomposes the organisms deposited on the membrane surfaces while being environmentally desirable. The detergent preferably also includes at least one bivalent iron salt, which improves the cleaning capability of the percarbonate via the so-called Fenton's reaction in which hydrogen peroxide adducted in the percarbonate reacts with the iron ions to form OH— radicals which have a very high oxidative reactivity. The detergent may also contain other oxidizers, a surfactant, a chelating agent, an acid and a pH regulator. The detergent is dissolved in water prior to use.
摘要:
A video camera has a body with an imager therein for providing a video signal in response to the projection of a light image thereon by a selected exchangeable lens device removably mounted on the camera body, and first and second computers in the camera body and lens device, respectively, which are programmed so that, in an initial communication sequence therebetween after the selected lens device is mounted on the camera body, the second microcomputer transmits optical characteristic data for the respective lens device to the first microcomputer in response to a data transmission request signal from the latter, and further so that, in a control communication sequence which follows the initial communication sequence, the first microcomputer transmits a control signal to the second microcomputer on the basis of the received optical characteristic data and a controlled status signal supplied to the first microcomputer from the second microcomputer. Further, upon the mounting of the selected lens device on the camera body, the existence of adequate electrical connections therebetween is readily detected.
