Title: Production of impeller for blower
Inventor: ZUSHIDA MISAO
IPC: F04D29/28
Filed: 1978-10-30
Abstract: PURPOSE: To make needless complicated metallic molds and to reduce the cost of a blower by forming vanes and vane fixer plates through die cutting from a cardboard.  
     CONSTITUTION: Vanes 11 and vane fixed plates 12 are formed by die cutting from a carbdoard. This results in that they can be produced with extremely small thickness, the dimensions of curvature of the vanes 11 can easily be realized as desired, and the weights of the vanes 11 and the plates 12 can be reduced, leading to saving of driving energy and of resources. In addition, the whole surface of the vanes 11 and the plates 12 assembled integrally is coated with a thermosetting or cold-setting resin solution by one of methods of application, spraying, and dipping. This enables production of an impeller wherein the vanes 11 and the plates 12 are provided with enhanced resistance to moisture and heat, durability, weather resistance, and rigidity.

Title: Device for applying tension to needle thread of sewing machine
Inventor: TAMURA MASASHI
IPC: D05B47/02
Filed: 1995-05-31
Abstract: PURPOSE: To miniaturize a thread tension disc without causing inconvenience by interposing a thread tension spring between a spring receiving member and a moving member and by providing an operating member for operating the spring receiving member so that a second thread tension disc is to be in the direction apart from a first thread tension disc. CONSTITUTION: When a tension of thread is released, an operating member 17 is operated to the left side. The center part is brought into contact with a projecting part 10a of a supporting stand 10 and a tip 17b presses the end face of a flange 14b of a spring receiving member 14 by leverage. The spring receiving member 14 moves to the right side against an energizing force of a thread tension spring 15 and a thread becomes not clamped between first and second thread tension discs 12, 13. In this case, the second thread tension disc 13 is fixed to the spring receiving member 14 and the spring receiving member 14 is operated by the operating member 17, thereby releasing the tension of the thread.  Therefore, even when the discs 12 and 13 are set as small as possible, it is unnecessary to secure a lot of inclination amount of the second thread tension disc 13 so as to easily arrange a thread.

Abstract: PURPOSE:To utilize easily optional image information of a raster type by converting it to image information conforming to an NAPLPS system, by representing each picture element of an image of a raster type which is inputted with an intermediate data consisting of color information and position information, and converting it to image information consisting of a prescribed command train. CONSTITUTION:A position segmented by trimming, namely, a coordinate is read, and subsequently, whether a trimming size is non-magnification or not is decided, and in case it is not non-magnification, the number of operands of an NAPLPS code is changed, based on the trimming size. A color of one picture element is read as color information of R, G and B data, but in this case, position information of its picture element is also read. As for this position information, it will suffice that it is, for instance, an absolute coordinate of a picture element on a display. In this way, its picture elements are represented by an intermediate data consisting of color information and position information, respectively. Subsequently, this intermediate data is converted to a prescribed command train confirming to an NAPLPS system.

Working oil increasing temperature by reciprocating and driving the concrete piston is discharged from a hydraulic cylinder and introduced to the inside of a jacket 12 through hydraulic piping 13. The temperature-increased working oil exchanges heat through the peripheral wall of the fused concrete and the cylinder 11 to be cooled, and reflexes from hydraulic piping 14 to an oil tank. Concrete which takes heat is extracted to the user. Thereby power of working oil cooling is not needed, and energy saving can be relized.
