Title: Method and device for controlling different peripheral speed rolling
Inventor: MIYASAKA KIYOTO
IPC: B21B1/22
Filed: 1984-05-02
Abstract: PURPOSE:To perform stable rolling avoiding chattering by starting rolling by uniform speed rolling, and changing to different peripheral speed roling when the rolling speed exceeds a preset speed, and then making automatic plate thickness control under specified consitions. CONSTITUTION:Electric motors 6, 7 are started at the same speed and at low speed by a command of a speed controlling device 10, and then accelerated at the same acceleration. Uniform speed rolling is performed up to a preset speed, and different peripheral speed rolling is started by a command from the device 10 when the preset speed is exceeded. When the plate thickness rolled by different peripheral speed rolling arrived at a thickness detector 11, a changeover switch 12 is made on, and a screw down controlling device 13 is operated according to a thickness signal. Automatic plate thickness control is made by a screw down cylinder 14, and a strip S of specified plate thickness is obtained. Chattering is not generated during uniform speed rolling, and stable rolling can be made at high-speed automatic plate thickness control.

IPC: A61B5/352
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To simultaneously collect good dynamical and quantitative information about an object in a very short time. SOLUTION: An object, e.g. a human heart, is scanned by a two-dimensional image collecting device to collect its tomograms. An image scanning device 4 scans the object by moving over a predetermined angle increment matching a predetermined number of times. After the tomograms and corresponding positions are digitized and recorded, the contour of the object in the tomograms is detected to convert the tomograms into a three-dimensional data set to originate a wire frame volume model showing the outer surface of the object using a three-dimensional method. The wire frame volume model is originated by linking the three-dimensional coordinates of a predefined contour or the subject by use of, e.g. interpolation algorithm.

Filed: 1982-05-27
Abstract: PURPOSE:To measure the number of revolution, by irradiating a converging beam to a small reflector installed to an axle or a reinforcing material of a wheel, and detecting and counting a periodical variation of its reflected wave. CONSTITUTION:When a coherent radio wave having short wavelength, generated by a transmitter 1 is radiated to a reflector 7 rotating together with a wheel 6, by a converging beam 4 from an antenna 3 through a circulator 2, the reflected wave passes through the antenna 3 and the circulator 2 and is mixed with a part of the transmitted wave by a mixer 8. On the other hand, when the wheel 6, accordingly, the reflector is rotated, the reflected wave is subjected to a Doppler shift, also, its intensity is varied in synchronization with rotation of the wheel 6, and a waveform is obtained in an output of the mixer 8. Accordingly, when this receiving electric power is detected by a detector 9, a video pulse having a repeated period which is equal to a both-wheel rotation period T is obtained, therefore, the number of revolutions of the wheel is obtained by measuring this period T by a counter 10.

Abstract: PURPOSE:To eliminate disadvantages such as adverse effect due to a dark electric charge and the limit of a consecutive shot speed at high speed consecutive shot by adopting the constitution such that the scanning method of a solid- state image pickup element is designed to obtain a required signal even in either odd field or even field at the time of field recording mode. CONSTITUTION:With the field recording mode selected by a recording mode changeover switch 19, a scanning method changeover switch 11 is changeover to the position of a terminal B. A 2nd drive signal reading simultaneously two adjacent horizontal rows by one horizontal scanning and reading the signal of the entire pattern is led to the terminal B. In the scanning of the 2nd drive signal, the set of the two horizontal rows to be read simultaneously by one scanning in both the odd field and the even field is the set of the two horizontal rows where the arranged color filters are the same and a signal required for the same signal processing method as that at the frame recording mode in case of the readout at any field period is obtained at the output of a signal processing circuit 5. Thus, even at the time of the field recording mode, the signal is read synchronously with the vertical synchronizing signal just after the end of pickup.

Abstract: PROBLEM TO BE SOLVED: To remove and recover dust contained in air and to remove and decompose harmful gas by installing a honeycomb electrode constituted of a porous body containing a catalyst and also providing a housing case in which a ventilation opening for discharging an ionic wind to the outside is formed. SOLUTION: When a power switch 31 is turned on, corona discharge is generated between a honeycomb electrode 10 and a discharge electrode 20, and by this, air around both the electrodes is negatively ionized. Then, this air enters cells 11 of the honeycomb electrode 10 together with neutral air, and a part of the negatively ionized air receives an electric charge of the honeycomb electrode 10 and is neutralized. An ionic wind A formed at this time flows to the discharge electrode 20 and the honeycomb electrode 10 and passes through the cells 11 and blows out to the outside from a ventilation opening 411. Fresh air is taken in through a ventilation opening 412 by such a flow of the ionic wind A, but dust in air is recovered by a filter 50 installed in the ventilation opening 412.

Abstract: PURPOSE:To detect a flaw without omission regardless of the size thereof, by irradiating the surface of an object to be inspected with beam having wavelengths, whose difference in the reflectivities to the surface and lower layer parts of the object to be inspected is 0.8 or more, from a beam irradiation system. CONSTITUTION:The laser beam emitted from the beam emitting part 11 of a beam irradiation system 10 is allowed to irradiate the surface of an object 30 to be inspected by a polygon mirror 12 to optically scan said surface in the lateral direction thereof. This irradiation beam is reflected from the surface of the object 30 to be inspected to be incident to a beam receiving detection system 20 while the detection system 20 receiving said reflected beam detects whether a flaw 33 is present on the surface of the object 30 to be inspected on the basis of the quantity of said reflected beam. At this time, the beam having wavelengths whose difference in the reflectivities to the surface layer part 31 an lower layer part 32 of the object to be inspected is 0.8 or more is used. Therefore, when the flaw 33 is present in the surface layer part 31 of the object 30 to be inspected and the lower layer part 32 is exposed from said flaw 33, the quantity of regular reflected beam incident to the detection system 20 from said flaw part is reduced and the flaw 33 can be detected without omission by he detection system 20.
