Abstract: PURPOSE:To prevent generation of a turbulent flow so as to enhance the propulsion efficiency of a water jet propulsion device by providing a drive shaft in a propulsion water passage with a shaft cover whose perpendicular cross section take such a shape as having a fundamental circle and inscribing arcs extending upward and downward from the fundamental circle. CONSTITUTION:A shaft cover 35 surrounding a drive shaft 13 is provided within a water passage. The cross section of the shaft cover 35 perpendicular to the axis thereof takes such a shape as having a fundamental circle 40 concentric with a through hole 38, an inscribing arc 41 (radius R1) extending upward and an inscribing arc 42 (radius R2) extending downward. The inscribing arc 41 extending upward is connected at its upper portion to an inscribing arc 43 (radius R3) of inversed R and the inscribing arc 43 is connected to a top plate 11. The cross section of the shaft cover 35 is gradually varied toward the front side as the drive shaft 13 crosses the top plate 11; i.e., the center of the fundamental circle 40 comes close to the top plate 11 and only the shape of the inscribing arc 42 extending downward is unchanged. That portion of the shaft cover 35 which is protruded above the top plate 11 is formed into a support portion 14. Water A for propulsion is allowed to flow smoothly along the shaft cover 35.

Filed: 1982-03-31
Abstract: PURPOSE:To checks the advance of a sequence all the time by an address comparison and to detect a fault immediately, by comparing the output of an address storage device with that of a comparison address storage device which generates expected addresses successively according to the progress of a program. CONSTITUTION:A microprocessor MPU outputs a storage address of a control memory CS to a comparing circuit CMP. Prior to the start of operation, addresses of the program of the microprocessor MPU are written in a buffer memory BF in specific order. The addresses of this memory BF are read by a clock RCK and compared with a program address MPA by the circuit CMP when the comparison address is generated. The comparison output of this circuit CMP is applied to a logical circuit together with a comparison enabling signal and when the comparison result shows coincidence, an FF is set. Thus, the advance of the sequence is checked all the time to detect a fault immediately.

Title: Optical disk apparatus
Inventor: KUWAYAMA YASUNORI
IPC: G11B7/085
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To provide an optical disk apparatus which can stop a pickup accurately at a required position and shorten an access time. SOLUTION: When an access mode is selected, a thread drive voltage of a predetermined voltage level is applied to a thread driver 26 from a DSP 20, and a pickup 16 is accelerated in the radial direction. When the pickup 16 reaches a predetermined count of tracks before a target position, the voltage level of the thread drive voltage is set to a low value. At the same time, a turnover voltage (moving speed signal) corresponding to the revolving speed of a thread motor 24 is superposed to the thread drive voltage. In other words, when the pickup 16 is to be braked, a brake voltage (control voltage) of a negative polarity of a level corresponding to the revolving speed of the thread motor 24 is applied to the thread driver 26. Accordingly, the moving distance of the pickup 16 due to inertia can be reduced, so that an access time is shortened greatly.  Moreover, the moving speed of the pickup 16 can be increased.

A prescribed detecting error epsilon of a positional signal by dead time is inputted to the input of the adjuster 52 as the offset voltage via the adder 56 and when the signal theta is sampled in the signal thetao=0 by a prescribed formula, an output signal is made thetaM-epsilon and the detecting error epsilon is added to this and the detecting error can be compensated regardless of the speed.
