Abstract: PURPOSE: To perform a satisfactory display by inhibiting the phase comparing operation for generating a clock in accordance with the state of the symnchronizing signal in an input video signal to prevent the clock from being disturbed in the case before and after the synchronizing signal is changed. CONSTITUTION: A clock generating part 104 is constituted of a PLL, circuit in which a phase comparator 305, charge pump type loop filters 306 to 308, a voltage controlled oscillator(VCO) 301 and a frequency diveder 304 are made to be basic constitutions. The polarity inversion circuit 302 of the clock generating circuit 104 is controlled by judging whether the detection edge of a next HD synchronization is to be made to be a rising edge or a falling edge. At this time, the phase difference detecting operation is made so as not to be disturbed by making a phase comparison enabling signal cs305 to tempolarily be in an inhibition state (an operation inhibition state) before and after the polarity inversion.  Thus, the state of the synchronizing signal in the input video signal is detected and the phase comparing operation in the clock generating part 104 is inhibited in accordance with the detection result.

Filed: 1987-05-27
Abstract: PURPOSE:To prevent the generation of the twist and camber of a stock to be formed by setting the clearance of a roll groove face in unloading state larger than the strip plate thickness at a bearing side. CONSTITUTION:The clearances 6-1, 6-2, 6-3, 6-4, 7-2 and 7-3 composed of the upper roll pieces 4-4, 4-2 and lower roll pieces 5-7, 5-6, 5-4 and 5-3 of an A row and B row are taken about the same as the thickness (t) of the stock to be formed. The clearances 7-1 and 7-4 composed of the upper roll pieces 4-4, 4-2 and lower roll pieces 5-8, 5-2 are set larger than the plate thickness (t) in unloading state. In this case, the clearances 7-1, 7-4 are found from the displacement at loading time of rolls 4, 5 with the forming reaction force as a center one point concentration load. The local rolling of the stocks 3-1, 3-2 to be formed is thus eliminated even if the displacement of the rolls 4, 5 at loading time be generated and the generation of twist and camber at forming time is prevented.

Abstract: PURPOSE:To make it possible to know a load weight at all times by a method wherein an amount of elevation of a chassis corresponding to the amount of a load on a vehicle is converted into a display amount to display the weight. CONSTITUTION:A shaft part 3a in the upper end of a detecting cylinder 3 is fitted rotatably to a bracket on the lower side of a rear body of a vehicle, and the lower end of a bolt 8 fitted to the lower end of a spring cover 5 is fitted rotatably to a bracket of a differential gear box. When goods are loaded on the rear body, the rear body lowers in proportion to the weight of the goods. Then a piston in the cylinder 3 moves upward in the cylinder 3 as indicated by an arrow 32, and therefore an oil in the cylinder 3 flows through a hose 18 as indicated by an arrow 33. Since a piston in a display cylinder 19 is pushed consequently in the direction of an arrow 34, a slide plate connected to a piston rod moves in the same direction. Then a display plate 25 is moved thereby in the same direction through the intermediary of a slide piece fitted freely to a slanting groove of the slide plate. By watching this movement through a display window 43 of a display case 42, therefore, the weight can be read from a scale 35.

IPC: H04N5/14
Filed: 1980-09-22
Abstract: Band limited standard video signals are sampled with line coupled sampling clock pulses. The sampling clock pulses are shifted from field to field by one-half a sampling interval. The sampling clock pulse rate is twice the frequency at the center of the Nyquist edge of the transmission channel. The received signal is sampled in synchronism, line coupled and offset from field to field. A video memory records the sampled values and furnishes them to the monitor at twice the sampling frequency and without flicker as a full frame. The video playback takes place at twice the line frequency or alternatively with the same line frequency and synchronous spot wobbling.

Filed: 1978-10-25
Abstract: PURPOSE:To give a transitional rotary movement with a preset turning radius similar to an astronomical orbit to a surface plate for mounting an electrode, without turning the plate, by vertically controlling the position of an orbital guide. CONSTITUTION:An internally conical surface 5 is formed at the center of an orbital guide 4 of a spark erosion machine. Since an oscillating body 9 is linearly transferred to any position with regard to a frame 2, the body 9 is kept pressed in the direction of 360 deg as a stationary spindle 32 turns. A conical ring 11 is transferred being guided by the surface 5, so that the oscillating body 9, without turning on its own axis, makes a transitional rotary movement on an astronomical orbit, with an eccentricity of e as a turning radius. When the eccentricity is altered, the radial clearance between the electrode 29 and a work 30 is relatively increased or decreased. This method can machine various kind of holes by using a single shape of electrode.
