Title: Orthogonal transformation encoding method for picture data
Inventor: ANDO ICHIRO
IPC: H04N19/625
Filed: 1989-01-31
Abstract: PURPOSE:To reduce the pressure rates of coefficients except the valid coefficient in an encoding area by detecting the largest degree of the largest coefficient set on each coordinate axis and deciding the encoding area with a superplane, etc., including a valid coefficient of the largest degree defined as a boundary. CONSTITUTION:A largest degree detecting circuit 2 compares (n) sets of transformation coefficients set on each coordinate axis with each threshold value for each block B and decides the conversion coefficients larger than the threshold value as the valid coefficients. Then the largest degrees a1, a2,...an of the valid coefficients of the largest degrees are detected for each coordinate axis. As a result, the detected largest degree data is outputted. An encoding area deciding circuit 3 receives the largest degree data from the circuit 2 and decides an encoding area Z in the block B based on the received data to produce the address data on the coefficients included in the area Z. Thus it is not required to perform the comparison with the threshold value even for an intermediate coefficient set between the coordinate axes. Then the encoding area can be decided by performing the comparison with the threshold value for only the coefficient set on the coordinate axis.

IPC: B01D35/06
Filed: 1984-02-09
Abstract: PURPOSE:To provide an electromagnetic filter having high filtration performance by improving the matrix of the electromagnetic filter. CONSTITUTION:An electromagnetic filter having high filtration performance is provided by using matrix for the filter prepd. by molding integrally pellets from magnetic metal fiber and a piezoelectric high molecular resin and agglomerating the pellets. The above described pellets 18 consist of magnetic metal fiber 20 and a piezoelectric high molecular resin 22; the two components are molded to lumps by compounding by extrusion. By this process, electroattractive force is generated on the surface of the matrix by the piezoelectric effect, and remarkably high filtration performance is obtd. by the synergistic effect with the magnetic attractive force. Since the electroattractive force generates by electromagnetic stress, therefore, the electroattractive force is eliminated by the suspension of power supply in the stage of backwashing together with eliminating of magnetic attractive force due to elimination of magnetism. Accordingly, the function of the matrix is restored and regenerated without requiring any particular operation by only performing similar procedure as performed conventionally in the stage of backwashing.

Abstract: PURPOSE:To obtain a control device, which properly controls braking of a mover further with small size and low cost, by arbitrarily interrupting driving of a firction part so as to control braking force. CONSTITUTION:In this hydraulic system, a pressure of a oil in a hydraulic power source 4 is applied through an opening and closing valve 5 and a selector 6 in a direction (a) to a piston 3 driving an output shaft 2 in a direction (b). While in case of driving the output shaft 2 in a reverse direction, the direction of applying the pressure of oil is reversed by the selector 6. A fine moving actuator 8, having a friction part 7, is fixed to a cylinder 20, when the actuator 8 is contracted, the friction part 7 is detached from the output shaft 2, so that it can be freely driven. Next, when the actuator 8 is extended, the friction part 7 is brought into press contact with the output shaft 2, so that it can be braked by friction. Accordingly, by repeating at a high speed the action of extending and contracting the actuator 8 while by variably controlling ratio of contracting and extending conditions to the total time, braking force to the output shaft 2 can be controlled.

Filed: 1980-02-27
Abstract: PURPOSE:To conduct printing of various sizes without replacing a form cylinder by a method wherein the form cylinder is given a large diameter, travels only during contact with a platen and stops traveling during contact with others than the platen. CONSTITUTION:By a speed-regulated form cylinder 6c, the platen 6b comes in contact with pressure roll 6a and the printing paper 1 which travels by rotation of a travel regulating roll 7 and then printing is made on one contact area of the paper 1 with the platen 6b. On the other hand, when the end of the platen 6b comes in contact with the printing paper 1, the pressure roller 6a and the travel regulating roll 7 stop rotating and the printing paper 1 stops traveling. In this method, considering the lengths of parts other than the platen on the form cylinder 6b, the outer diameters and the speeds of rotation of each of the pressure roll 6a, the travel regulating roll 7 and a brake operation roll 5a, various kinds of printing are made through electrical timings.

Title: Endoscopic device
Inventor: SUZUKI AKIRA
IPC: G02B23/24
Filed: 1992-02-07
Abstract: PURPOSE:To eliminate the troublesomeness of switch operation when an insertion part is inserted or endoscopic examination, especially, precise examination is performed. CONSTITUTION:When an insertion part advance and retraction detecting circuit 9 detects the advance and retraction of an insertion part, various fine vibration modes are performed according to switch operation. When the insertion part advance and retraction detecting circuit 9 detects no advance and retraction of the insertion part, that is, when the insertion part is not advanced and retracted, a control circuit 28 controls speed control circuits 29a, 29b so as not to output pulses. Therefore, a curving part is not subjected to any fine vibration. However, usual curving operation can be performed. By this constitution, when precise observation is desired to be performed, it is unnecessary to advance and retract the insertion part and, since the advance and retraction detecting circuit 9 automatically detects the non-advance and retraction state of the insertion part in this device, the fine vibration of the curving part is stopped and the observation of an endoscopic image is made easy and the troublesomeness of switch changeover operation can be eliminated.

Abstract: PURPOSE:To decrease the abrasion of a belt and idlers by making the revolving speed of a motor as low as roughly equal to a ''low speed'' by a control means at the time when a tape is going to be run at a high speed. CONSTITUTION:A motor 1 is supplied with a driving power source from a power source 3 through a known control means 2. The means 2 detects the counterelectromotive force of the motor 1, and controls this so as to assume a reference value, thereby making the rotating speed of the motor 1 constant. This reference value is changed by whether an electric route 4 is closed or opened, and when it is closed, the motor 1 runs at a low speed. The switch 5 inserted in series to the route 4 is for changing over of the ''high speed'' and ''low speed'' of the constant running speed of the tape, and is operated to on when the tape speed is the ''high speed'' and to off when the ''low speed''. A switch 6 is turned on by the constant speed running operation of the tape, such as playback, and is operated to off at the tape high speed running such as fast forwarding mode other than this, and when the tape stops.
