IPC: E21B17/00
Filed: 1994-02-08
Abstract: PURPOSE:To provide a casing tube which can excavate the ground in order to draw out an existing pile without damaging it. CONSTITUTION:A spiral blade 16 in which an existing pile 15 can be inserted is formed at the inner periphery of a casing tube 10 having a diameter with which the casting tube defines a predetermined gap A between itself and the outer periphery of the existing pile 15, extending from the front end to rear end of the casing tube 10 which is therefore thrust into the ground by swinging or rotating the casing tube 10. The ground is excavated by cutting blades 17, 18 at the front end of the casing tube 10 while sediment around the pile 15 is discharged upward in order to remove friction between the pile 15 and the ground, thereby it is possible to easily withdraw the pile 15.

Filed: 1986-01-27
Abstract: PURPOSE:To extend the system scale of a cordless interphone by providing a radio repeater, which is connected to a slave device with a wire, in the slave device side installed outdoors. CONSTITUTION:A radio repeater (transmitter-receiver) B is connected to an outdoors installed device A through a wire transmission line 4. When receiving a call from the slave device A, a power supply control circuit 55 of the repeater B operates the repeater B for a certain time and modulates a ringing tone, which is generated in a tone generating circuit 54, by a modulating circuit 52 and transmits it toward a master device. When receiving a response signal from the master device, a carry detecting circuit 65 stops the operation of the tone generating circuit 54 and extends the power supply time of the power supply control circuit 55 for service. If service radio waves are broken, the power supply control circuit turns off a power source after a certain time.

Abstract: PURPOSE:To highly efficiently manufacture a wall shaped thick steel plate by installing an edger in the vicinity of a finish rolling mill and deciding a plate thickness at start of finish rolling based on effects by the edger and respective rolling efficiencies of rough and finish rolling mills. CONSTITUTION:A rough rolling mill 8 and a finish rolling mill 9 are installed in the outlet side of a heating furnace 7 and an edger 6 is installed in the upstream or downstream side close to the mill 9.

Abstract: PURPOSE:To securely recognize characters without fail by identifying any one of candidate characters as the objective character of recognition while referring the number of coincident picture elements when the plural candidate characters are detected. CONSTITUTION:A reference picture stored in a picture memory 13 is read out by an MPU 15 and registered to a pattern memory 22 as a template. A coincidence degree calculation part 21 calculates a ratio between the number of picture elements in the input picture coincident with the picture elements (black picture elements) constituting the character area of the template and the total number of black picture elements constituting the character area of the template as the degree of coincidence, and a coincident point detection part 24 compares this degree of coincidence for these picture elements with a prescribed threshold value and detects the characters of the template as the candidates for the objective character of recognition. As identification part 23 identifies any one of the candidate characters as the objective character of recognition when the plural candidate characters are detected. Thus, even concerning the similar character or even when noise or the picture of the adjacent character is included in the character, the objective character of recognition is identified without fail.
