Title: Tracing device
Inventor: SAITO YUKIHIRO
IPC: G06F11/28
Filed: 1988-12-07
Abstract: PURPOSE:To judge which condition branching instruction has been branched by respectively separately storing information, which indicates the formation of the condition, and information, which indicates the nonformation of the condition, corresponding to the addresses of microinstructions when the microinstruction is the condition branching instruction. CONSTITUTION:When the microinstruction read from a control storage 1 is the condition branching instruction, a branching condition check circuit 8 decides whether or not the condition of the microinstruction is formed. When the condition is formed, the formation of the condition is recorded in the address corresponding to the instruction of a memory 12, when the condition is not formed, the nonformation of the condition is recorded in the address corresponding to the microinstruction of a memory 13. Thus, even when the branching destination address is the same in the plural condition branching instructions, which condition branching instruction is branched can be judged.

Filed: 1989-11-28
Abstract: PURPOSE:To even the degree of wear of a medium by including a procedure to maintain the same head contact time per unit area and a procedure to determine the contact of a head with all tracks as the execution unit of cleaning. CONSTITUTION:The time for contact of the head is previously determined by the lengths of the circumferences of the respective tracks of the floppy disk medium for cleaning and the rotating speed of a floppy disk drive. For example, the number of the tracks per side of a 5.25-inch floppy disk medium is determined as 80 tracks and the lengths of the circumferences of the track 00 and the track 79 are determined respectively as 377mm and 195mm. The rotating speed of a floppy disk drive is set at 360rpm. The time when the head is brought into contact with the tracks 00, 79 is 377ms and 196ms, respectively, when the head is assumed to be brought into contact with the tracks for A1 second per unit area. The seek head is first brought into contact with the track 00 and after lapse of the regulated time, the head is sought to the track 01 and the head is similarly brought into contact with the track for the regulated time. This contact is similarly executed up to the track 79 by the regulated time for the respective tracks, by which the execution unit of the cleaning is ended.

Reference lumious flux, on the other hand, is reflected by a mirror M1 by 90 deg., passed through a lens L1, and converted on the light incidence terminal of an optical fiber F through another window of a front panel Q. The optical fiber F runs along the side wall internal surface of the external sample chamber OS and the reference light is incident on the integrating sphere IS almost at right angles to the sample luminous flux. Further, a photodetector D2 is arranged opposite the light guide-out window of the integrating sphere IS and the photodetection unit is fitted slidably on a guide almost at right angles to the sample luminous flux incident on the integrating sphere IS.

Abstract: PROBLEM TO BE SOLVED: To make the circuit improved in output accuracy, simplified in circuit configuration and improved in responsiveness by disconnecting invalid feedback capacitance from a floating node to eliminate an effect to the floating node and applying a reference voltage to both ends when refresh is performed. SOLUTION: Feedback multiplexers: MUX1 to MUX6 are switched by control signals S1 to S6 controlling the validity/invalidity of feedback capacitance Cf1 to Cf6, invalid input sides in the capacitance Cf1 and Cf2 are disconnected from a floating node and are connected to a reference voltage VREF.
