Title: Suction shut-off device in vane type rotary compressor
Inventor: MATSUDA TOSHIO
IPC: F04C28/10
Filed: 1983-12-28
Abstract: PURPOSE:To aim at preventing inferior compression etc. upon starting in a low rotational speed range, by providing such an arrangement that when a difference in pressure of a compressor is small, a spring urges a spring to reduce the cross- sectional area of a suction passage so that a vane is surely pressed against the cylinder inner wall. CONSTITUTION:When a difference in pressure of a compressor is zero or small since the compressor is rested for a long time, the pressures upstream and downstream of a valve element 26 are balanced together so that the valve element 26 is moved toward a first slide chamber 24a by the resilient force of a spring 31. Therefore a suction passage 19 is communicated, having a slight cross-sectioned area, solely with an annular groove 32. When the compressor is started in this condition, no sufficient fluid flows so that the pressure in a low pressure space downstream of the valve element 26 drops. In association with this pressure drop the pressure in a working chamber 8 lowers so that a force acting upon the tip end of a vane to introduce the latter into a vane slot 4 also becomes small. As a result the vane 3 is surely pressed against the cylinder inner wall to continue the normal operation of the compressor.

Title: Method for segmenting and recognizing character
Inventor: NAKAMURA KOKI
IPC: G06K9/34
Filed: 1993-09-14
Abstract: PURPOSE:To make it possible to simply and accurately segment a character string written like a circular arc and to accurately recognize a dot character by rotating a work on which characters are printed. CONSTITUTION:A camera 4 inputs the whole circular arc constituted of a character string 2 as binary data and a camera 6 fetches three characters out of the character string 2 also as binary data. An area value measuring part 9 counts the number of pixels in a window which are set up for 360 deg.C in each fixed angle on the circular arc based on the data inputted by the camera 4 and stores the angle and area of the circular arc. A character string segmenting part 10 finds out rough positions for the edge points (start point and end point) of the character string 2. Then the work 1 is rotated to find out the accurate positions of the edge points based on the data inputted by the camera 6. A character segmenting part 11 rotates the work 1 so as to display three characters each in the visual field of the camera 6 and a character recognizing part 12 recognizes characters based on the picture inputted by the camera 6.

Filed: 1987-10-05
Abstract: PURPOSE:To obtain a smooth zoom picture by prohibiting focusing operation during zoom operation with the change of a second evaluating value or the relative change of the second evaluating value to a first evaluating value. CONSTITUTION:A high frequency component level in a central sampling area E1, which is set to a screen center, among image pick-up luminance signals to be obtained by an image pick-up element is obtained as the first evaluating value. Then, the high frequency component level in a circumferential sampling area E2, which is set to the circumference of the central sampling area E1, among the image pick-up luminance signals is obtained as the second evaluating value. Then, the focusing operation during the zoom operation is prohibited by the change of the second evaluating value or the relative change of the second evaluating value to the first evaluating value. Accordingly, the change of a picture angle to accompany the zoom operation is prevented from giving an influence to the focusing operation. Thus, the zoom picture, which is smooth and easy to be observed, can be obtained.

Title: Core for forming receiving mouth of cast iron pipe
Inventor: TAKEUCHI KATSUYUKI
IPC: B22D17/22
Filed: 1989-09-27
Abstract: PURPOSE:To prevent the scale of the inner surface of the receiving mouth of the cast iron pipe manufactured with the centfugal casting method from generating by forming the film coating of Al material on the surface of the receiving mouth forming side of the core. CONSTITUTION:The core 1 for forming the receiving mouth is set at one end side of the water cooling die 2 for the centfugal casting. The core 1 is formed of the casting sand containing the organic tacky adhesive agent and the film coat 4 of Al or Al alloy is formed on the surface of the receiving mouth forming side. The film coat 4 is melted with the heat of molten cast iron at the time of casting. And because its sp.gr. is small, it is not mixed in the molten iron, and so it is stuck on the inner surface of the receiving mouth of the formed casting iron pipe and the inner surface of the receiving mouth is coated with it. At the time of the annealing treatment, the film coat 4 is exposed in the oxidized atmosphere and the oxidized product of Al2O3 is generated, and the inner surface of receiving mouth is protected from the oxidizing atmosphere. Therefore, the generation of the scale of the inner surface of the receiving mouth is prevented. When the particles of Al (alloy) material are stuck on the core 1 in place of the above film coat, the generation of the scale of the inner surface of the receiving mouth is also prevented.
