摘要： A compact video camera has an image pickup lens system providing a zooming function and a wide angle field of view. The zooming function is performed by a zoom lens, while the wide angle view is achieved via a wide angle converter. The wide angle converter, located closer to the object than the zoom lens, comprises a negative lens, a positive lens, and a reflecting member located between the negative and positive lenses. With the use of the reflecting member, an optical axis of the image pickup lens system extending from the object side to the image side of the camera may be folded. The position at which the optical axis is folded is located closer to the object side than the image side.

摘要： In a powder coating material feeding apparatus, a lid section is mounted onto an opening of a metal drum containing powder coating material, and a support unit holds the metal drum in its upside-down or tilted position. An air distribution panel supplies carrier air into a conveying hose via a carrier air supply port, opens a pinch valve, activates a vibrator, and supplies fluidizing air into an air chamber in the lid section to fluidize the powder coating material in the metal drum. With this arrangement, the powder coating material is drained into the conveying hose through a drain port in the lower end of the metal drum in its upside-down position, and is then transferred to a powder tank by the carrier air.

摘要： A zoom lens is provided, in which a fixed first lens group having a positive refracting power, a second lens group having a negative refracting power and which realizes a variable magnification, a fixed third lens group having a positive refracting power and a fourth lens group having a positive refracting power which compensates fluctuation of an image surface caused by the variable magnification and which focuses an image are sequentially provided from an object side. In this zoom lens, the third lens group is composed of two separate lenses of a positive lens (31) and a negative lens (32). At least one surface of the positive lens (31) is formed as an aspherical surface and a surface of the negative lens (32) opposing the image surface side is concaved to the image surface side. Thus, the zoom lens of this invention can be miniaturized and reduced in weight without deteriorating the characteristics such that a variable magnification is large and that an F number is small.

摘要： A covered balloon for use as a toy or in a display, which includes a cover formed of a plastic film and a rubber balloon inside the cover. More specifically, the cover is formed of two superposed sheets of substantially gas impervious plastic film whose peripheral edges are welded to form a seam. In a one embodiment, the cover and the rubber balloon each have a nozzle and the rubber balloon is inflated so as to fill the entire space within the cover and eliminate any wrinkles in the cover and adhere to an interior surface of said cover with the nozzle of the rubber balloon protruding from the cover through the nozzle of the cover. A welding flap formed along the seam when the cover is formed by welding together the plastic sheets, may be substantially reduced in size by cutting the flap along the seam. The cover may be formed of a transparent film such as a film of ethylene-vinyl alcohol copolymers so that the rubber balloon inside is visible. According to another embodiment, the rubber balloon fills only a portion of the space within the cover, the remainder being inflated with a gas.
