Title: Measuring device for decrease in wall thickness
Inventor: SUZUKI KAZUMICHI
IPC: G01B17/02
Filed: 1981-05-13
Abstract: PURPOSE:To reduce scanning by a wave sending and receiving device and detect minimum wall thickness and its position in a short time by sending a surface wave to an object to be measured and making its frequency gradually larger and detecting the time for the wave to reach a wave receiving device through a reduced wall thickness portion or the time for the reflected wave to reach the wave receiving device. CONSTITUTION:Continuous sine waves from an oscillator 10 become pulse-type sine waves at a gate circuit 11 by means of a trigger pulse generated in a micro-processor (MP) 9, and they are applied to a wave sending and receiving unit 3 via an amplifier 12. The surface waves are received by a receiver 5, and its signal is input to a counter 19 through an amplifier 17 and a pulse shaper 18, and the clock pulse from a pulse generator 13 is counted. The value of the counting for the time (tau) from oscillation of the surface waves to the time of receiving them is stored in the MP9. When it falls within a specified value by changing the frequency (f), the thickness of a part 2 where wall thickness is reduced is calculated. The waves reflected from the part 2 are detected at the waqve sending and receiving unit 3 and from the going and returning time of surface waves detected in the same way the position of the part 2 is detected.

Filed: 1987-03-26
Abstract: PURPOSE:To improve a magnetic effect and reduce in size of this device by making the thickness of an end side of a yoke thin and by causing an armature to have the other side of a yoke at a thickwalled part where its thickness is almost equal to that of the armature and also to have an end side of the yoke at a thin-walled part where the sum of the thickness of its end side and that of the armature is almost equal to that of the other side of the yoke. CONSTITUTION:An armature 7 allows the other side 6b of a yoke to be formed at a thick- walled part 7a where its thickness is almost equal to that of the armature and also allows an end side 5b of the yoke to be formed at a thin-walled part 7b where the sum of the thickness of its end side and that of the armature is almost equal to that of the other side 6b of the yoke by making the thickness of the end side of the yoke 4 thin. When the thin-walled part 7b is in a position of operation by being sucked to the end 5b of the yoke, it holds a position in the almost same plane as the other end side 6b of the yoke. Since the armature 7 is located in an air-core part 2 of a coil, it not only serves the purpose of improving a magnetic effect but also permits magnetic paths consisting of the armature 7 and the yoke 4 to become uniform cross-sectional areas nearly through the whole area, no partial magnetic saturation develops and this device is reduced in size by lessening the cross-sectional areas of the air-core part 2 as well. And with the decresse of the weight of its armature 7, it is also operated at great speed.

Title: Rolling method for clad material
Inventor: KIMURA TOMOAKI
IPC: B21B1/38
Filed: 1985-04-05
Abstract: PURPOSE:To decrease the protrusion arising from the rolling of a clad material by forming preformed parts each having a parallel part and taper by local rolling to the front and rear ends of the clad material prior to rolling of the entire part then subjecting the material to the rolling over the entire part. CONSTITUTION:The clad material in a hot state is thinly rolled from the thick state of a plate thickness with a good yield in this method. The general material 2 side is more likely to elongate as compared to SUS1 and therefore the material is ironed by rolling rolls 3, 4 to generate a projection 32 when the clad material is successively rolled by the rolls 3, 4. The generation of such projection results in the decreased yield. The preformed parts each having the parallel part L0 and the tapered part by local rolling are thereupon provided to the front and rear end of the clad material prior to the rolling over the entire part and thereafter the rolling over the entire part is executed. As far as the preformed parts are provided thereto, the preformed parts restrain the projection even if the material is going to project in the stage of rolling the central part. The rolling with the decreased projection is thus made possible.

IPC: B41J19/18
Filed: 1986-03-31
Abstract: PURPOSE:To fine-adjust the feed control timing of a printing head thereby correct a positional shift by detecting an actual printing position optically in each printing line when printing in a vertical ruled line in the normal and reverse direction printing modes. CONSTITUTION:In a printing control part 17, an amplifier 31 amplifies and output signal of a photosensor 14 and a pulse shaping circuit 32 shapes the pulse of the signal and a sampling circuit 33 samples the signal. In each printing line in normal and reverse directions, a vertical ruled line position pattern extracted by a shift register 34 is stored in an individual address of a vertical ruled line position memory 35. A positional shift detection logic circuit 36 compares a vertical ruled line position patterns in normal and reverse printing directions which are stored in the vertical ruled line position memory 35. Thus a shift amount and a shift direction are detected and if the shift amount is larger than prearranged threshold, it is stored in a shift amount register 37. Further if a shift is made in a normal shift direction, a normal direction shift indicator FF38 is set to ON. If the shift is made in a reverse direction, a reverse direction shift indicator FF39 is turned ON.
