Title: Drawing recognizing device
Inventor: KAMI HIROYUKI
IPC: G06K9/62
Filed: 1983-04-19
Abstract: PURPOSE:To recognize a character even when the character contacts a figure by excluding a binary image corresponding to a figure recognition result from the binary image of a drawing, and extracting a character image to perform character recognition. CONSTITUTION:A figure separation part 3 separates the binary image of an image storage part 2 into a character and a figure and outputs only the pattern image, which is stored in a figure image storage part 4. The shape features are extracted from this figure image by a recognition part 6. A recognition result processing part 8 corrects the output of the recognition part 6 to generate a figure recognition result. A character separation part 9 excludes the binary image corresponding to the figure recognition result of the recognition result processing part 8 from the binary image of an image storage part 2 to ouput the binary image of the character. The segmented character image is recognized by a character recognition patt 11. Then, a drawing recognition result is outputted from the figure recognition result and the output of the character recognition part 11.

Abstract: PURPOSE:To improve the breadth accuracy of a hot rolling strip, by driving a mandrel on an inverter-system to absorb an excessive tension of the strip after starting the coiling of strip around the mandrel, and preventing the strip from necking. CONSTITUTION:An inverter-control switching-command circuit 20 judges whether or not to apply an inverter controlling basing on a mandrel-speed signal, generated in a speed-signal generator 18 provided to a driving motor 17 of a mandrel 15, and a mandrel load-current signal of a current detector 22, and keeps out of the inverter controlling when coiled unsmoothly. The signal of inverter controlling is transmitted to an inverter-current operating circuit 26 when judged possible, by means of the circuit 20. The circuit 26 outputs an electric power to a motor 17 through a current-voltage-controlling circuit 21 after determining the quantity of inverter current and start-up time basing on a strip-yielding-stress setting value SV. Thus, the motor 17 drives the mandrel 15 on the inverter system and, then an inertial energy in coiling strip 11 is absorbed and decreased.

IPC: F28D15/02
Filed: 1987-03-26
Abstract: PURPOSE:To make the mounting and dismounting of a heat pipe very easy and minimize the resistance to the contact heat which is generated at the insertion and attachment section by forming a cap which seals and closes the end of a container in a sturdy structure which withstands a powerful spiral rotation torque and external force for insertion and pulling-out and forming on the end face of the cap a structure of female type for insertion and pulling-out by spiral rotation. CONSTITUTION:For example, on a cap 2 both a structure section 3 of insertion and pulling-out by spiral rotation and a working liquid sealing section 4 of non-projection type are provided simultaneously. In the working liquid sealing section 4 of non- projection type a small diameter pipe 4-4 for sealing is crushed by a pin for crushing which is pressed in from a side hole 4-2 for crushing in a throughhole provided in the cap to seal the working liquid in the state that a crushing section 4-1 is incorporated in the cap. A soldering junction 4-3 improves the reliability of crushing in the crushing section 4-1. Because the projection section in the conventional device is not left, it is possible to carry out easily the spiral rotation work. Further, the heat pipe has no projection section entirely so that it is possible to make the effective length of the heat pipe when it is inserted longer.
