Abstract: PURPOSE:To improve coding efficiency by estimating optimum prediction in a present picture element from the state of a reference picture element. CONSTITUTION:A predicting function is counted individually, where the dynamic compensation interframe prediction and the interframe prediction take an optimum value in a picture element corresponding to an existing picture element for each state of a reference picture. It is estimated that the interframe prediction is the optimum prediction of the existing picture element in the reference picture element state where the probability P1 taking the interframe prediction as the optimum predicting function is large (P1>=0.5) and the dynamic compensating interframe prediction is the optimum prediction in other reference picture element states in each state obtained by the measurement like this, and the result is used as the prediction to the existing picture element. Since the method estimating the optimum prediction is executed even at the receiving side, it is not necessary to transmit the information which of the dynamic compensating interframe prediction and the interframe prediction is used.

Abstract: PURPOSE: To automatically control the elevating position of a movable ram and perform bending work of high accuracy with good efficiency by providing positioning adjustment mechanisms between position control members and selector valves.  
     CONSTITUTION: When a movable ram 7 ascends, position control members 75a, 75b of a wedge shape ascend as well. The slopes in the leading end parts of the members 75a, 75b slidingly contact and turn the other end parts of arm members 81a, 81b upward with fulcrums at pins 79a, 79b. At this same instant, push rods 123a, 123b also move upward, thereby connecting the 2nd selector valves 119a, 119b to tanks 127a, 127b, respectively. This makes the working pressure fluids from pumps P 1 , P 2  release to the tanks 127a, 127b, thereby stopping the ascending operations of fluid working devices 13a, 13b. Namely, the ram 7 stops in the state that it is holding the ascendable pressure.

Title: Rotating speed detector for bearing
Inventor: SUZUKI KEIJI
IPC: F16J15/3252
Filed: 1996-02-27
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components by fixedly engaging the mandrel of a sealer for sealing between the inner and outer races of a bearing with a race ring on the rotation side, and extending a pulser part to the outer peripheral side of the mandrel itself. SOLUTION: An outer race 1 forms two races 1a, 1b at a predetermined interval in the axial direction. An inner race 2 forms two races 2a, 2b corresponding to the races 1a, 1b. Balls 3, 4 are mounted between the races 1a and 2a and 1b and 2b. A rectangular hole 7 is spaced in the circumferential direction as an annular element by extending along the outside of the outer race at the mandrel of the seal for preventing the dust from being introduced between the outer race 1 and the inner race 2 to form a pulser ring 8. The ring 8 is engaged fixedly at the outside of the outer race 1. Thus, since the one component performs all the functions of the pulser ring, annular ring and mandrel, the number of components can be detected.

IPC: G06F12/12
Filed: 1979-05-25
Abstract: PURPOSE: To use a buffer memory effectively, by detecting the access of specific data in a block of a memory unit, which is stored in the buffer memory, to set the block as the first candidate for substitutional symmetry.  
     CONSTITUTION: An address is formed from upper bit parts in order, and the third address for discriminating data in a block indicates last data in the block, and all data in the block are accessed. When specific data detecting circuit 1920 decides this access, the logical output is inverted to 1. As a result, MLRU memory 20 based on the MLRU method obtained by modifying the system which selects the block whose last reference is oldest through OR gates 1143W1148 is read, and the block where all data are read out is set to the first candilate for substitutional symmetry; and since data accessed once has a low re-access frequency, the system is realized where the buffer memory is used effectively.

Filed: 1981-04-30
Abstract: PURPOSE:To manufacture the optimum device for high speed and high concentration by a method wherein the P<+> layer is connected to the N layers on the surface of the P type Si substrate and a conductor is provided on the boundary between the P<+> layer and at least one of the N layers. CONSTITUTION:The P<-> channel 14 is formed between the two N layers 2 and 3 on the P type Si substrate 1 and the gate 6 is further formed on the interface of the junctions with the N layer 2 through the intermediary of the SiO2 5. In this constitution, the junction breakdown on the interface between the source 22  and the channel 14 may be controlled by the impressed voltage on the gate electrode 6 to evade most of the conventional short-channel effect as well as to simultaneously restrain the breakdown from declining, the threshold level voltage from rising and the drain depletion layer from spreading, consequently the  leakage current may be minimized by means of increasing the channel concentration as much as possible within the limited voltage at the external circuit between the source and the gate while flowing most of the electric charge from  the source into the drain through the channel. Through these procedures, the  optimum device for high speed and high concentration with proper threshold  level and high beakdown strength may be manufactured.

Filed: 1983-04-15
Abstract: PURPOSE:To attain the simultaneous video recording with two video signals without increasing the number of magnetic heads by setting a >=180 deg. winding angle of a magnetic tape to a rotary cylinder. CONSTITUTION:The winding angle of a magnetic tape 3 is set at >=180 deg. by tape guides 4a and 4b to a rotary cylinder 1. Then the tape 3 is wound around the cylinder 1 via a main winding part theta having a 180 deg. winding angle, a sub-winding part alpha having a prescribed increased winding angle and a margin winding part beta which gives some margin to the winding angle range respectively. With such a winding angle range of the tape 3, both magnetic heads 2a and 2b having a 180 deg. angle space between them touch the part theta alternately for every revolution. In this contact section the 1st video signal is recorded and reproduced by an alternating switch action between both heads 2a and 2b. Thus these heads have contacts with the part alpha earlier than the part theta. In this contact section the 2nd video signal is recorded and reproduced.
