IPC: G06F12/10
Filed: 1980-03-28
Abstract: PURPOSE:To reduce the time required for a memory access, by processing Translation Lookaside Buffer (TLB) only at the generation of a page cross through the judgement if the page cross is generated or not. CONSTITUTION:When a part of the page address of the 1st address 3-1 of the logic address register 3, in-page address and operated number of the operated number register 4 are added at the operation device 5 and the page cross is produced at the address renewal, the bit output 19 from the address 3-1 and the output 20 from the operator 5 are inverted to high level. Thus, the judgement output of the check circuit 7 providing the NOT gates 9, 10, AND gates 13, 14, and OR gate 17 is inverted into high level and the page cross detection signal is generated and the index reference is fed to TLB6 where it is formed with the elements of the same speed as the memory unit 2 to produce the desired access address. Thus, even if the operated number is greater, no index processing is made at unnecessary time, allowing to reduce the access time.

Title: Error display circuit for self checking system
Inventor: PARASHIOSU ARUBERUTO
IPC: G06F11/32
Filed: 1992-02-27
Abstract: PURPOSE:To completely satisfy self-checking ability without generating any hazard or trace by synchronizing the operation of the error display circuit to the clock of a system. CONSTITUTION:Respective outputs are normally set to '1' and '0' by using the presets and clear inputs of D flip-flops 3 and 8. Outputs x1 and x2 of a checking circuit and outputs y1 and y2 of the error display circuit are turned to the inputs of transient relation composed of gates 1, 2 and 4-7 so as to decide the next state of the error display circuit. When the (x1, x2) is (0, 1) or (1, 0), (y1', y2') obtains this value and is turned to the outputs of the flip-flops 3 and 8 during the next clock period of a monitor processing system. When there is any degenerative fault in the output of the gate 4 and it is a '0' degenerative fault, the output is fixed to (0, 0) and in the case of a '1' degenerative fault, the outputs of the gates 1 and 6 are turned to the x1 and x2. Since the output of the gate 5 is normally '0', the y1' and y2' are turned to the x1 and x2, and the y1 and y2 are outputted during the next clock period.

Title: Precise moving unit
Inventor: MORIYAMA SHIGEO
IPC: G03F7/20
Filed: 1979-04-06
Abstract: PURPOSE:To make high-speed positioning of a moving material and high-precision movement possible by providing a backlash between a driving frame and a roller part. CONSTITUTION:Linear movement of the driving system consisting of combination of a DC servo motor, a ball screw, etc., is transferred to moving stands 7 and 15 through connection bars 20 and 21 of the XY axis. Driving rod 22 having a square cut part is fitted to the tip of connection bar 21, and roller part 23 is restricted in this cut part. Since the rotation axis of roller part 23 is fixed onto yaw slide piece 17, movement of connection bar 21 is transferred to moving stand 15. Since the width of the square cut part of driving rod 22 is larger than the outside diameter of roller part 23, moving stand 15 is guided only by rail 5 of the X axis without restriction of driving rod 22 and can move in the X axis direction also with a high precision without generation of yaw and damage of straight going. In case of movement in the Y axis direction, since roller part 23 is moved while brought into contact with driving rod 22, the control for providing a backlash is performed after Y axis positioning.

Abstract: PURPOSE:To simulate the taste and the smell of an organism and to detect many kinds of chemical materials by applying exciting light on two or more kinds of liposomes having different characteristics in suspension, and detecting the change in film potentil due to the exciting light as the change in intensity of fluorescence of each pigment at the same time. CONSTITUTION:As lipsomes B1 and B2, two or more kinds of the materials which are formed of different phospholipids A1 and A2 are prepared. Film- potential sensitive pigments C1 and C2 having different flurorescence wavelengths are added. The obtained lipsomes B1 and B2 are mixed into a buffer liquid. When a chemical material D is added into the turbidity liquid as a smelling material, the film potentials are changed in the lipsomes B1 and B2 correspondingly. The degree of the change is different based on the kinds of the material D and the constituent components of the lipsomes B1 and B2. The differences appear as the changes lambdaa and lambdab in intensities of the fluorescences. The changes are detected and measured.

Title: Abnormality detecting device for tape recorder
Inventor: HATSUDA TERUO
IPC: G11B15/02
Filed: 1987-02-26
Abstract: PURPOSE:To rapidly detect the abnormal state of a tape and to remarkably reduce the quantity of the winding of the tape by providing a means for incorpo rating a reel pulse in a specified period so as to decide the normality or abnor mality of a tape traveling state and a means for reversing a tape traveling direction with the decision of abnormality. CONSTITUTION:From the reel pulses generated by rotary disks 1 and 1' the numbers of rotation nS and nT of the respective reels are obtained by a control circuit 12 and an arithmetic operation based on formula 1 is executed from the numbers of rotation nS and nT. The computed result of the formula is constant if a tape cassette is decided. Therefore, when a constant C varies it is known that the abnormal state such as sagging, etc., occurs in the tape, so that the abnormal state of the tape can be detected. Since the abnormality is detected and the tape traveling direction is reversed by the controller 13 before the tape is wound in a capstan, etc., or while the quantity of the winding of the tape is small even if it is wound in, the winding of the tape can be completely prevented.
