Filed: 1993-07-28
Abstract: PURPOSE:To reduce data errors due to viterbi decoding by calculating a DC offset value from a signal amplitude of a test pattern of the lead of a block and setting an initial predictive amplitude value of the viterbi decoding. CONSTITUTION:Data to be recorded and reproduced are divided into blocks in a sector unit, and the lead of each individual sector is provided with a header area. The test pattern is recorded by using 2nd and 3rd segments out of three segments of the header area at the lead of each sector. At the time of reproducing the data from the disk, a regenerative signal is inputted from a terminal 25 and is converted into a digital value by an A/D converter circuit 14, and afterward, the regenerative signal of the pattern of the 2nd header is changed over and inputted to the side of a predictive control circuit 60 by a changeover circuit 70. An offset value showing how much a DC deviation from the predictive level of the regenerative signal should exist is calculated, and is also added to a predictive amplitude value which becomes a reference, and is then inputted as the initial predictive amplitude value to a viterbi decoding circuit 50 by the circuit 60. Then, the viterbi decoding is carried out by the circuit 50 in adaptably controlling the predictive amplitude value to be inputted from the circuit 60.

Title: Nuclear fusion method
Inventor: IWAMATSU SEIICHI
IPC: G21B1/00
Filed: 1990-07-13
Abstract: PURPOSE:To increase the efficiency of generation of thermal energy by accelerating and implanting deuterium ions into a hydrogen storage metal or alloy, thereby allowing the already stored deuterium atoms or injected deuterium atoms to collide with each other to produce nuclear fusion reaction. CONSTITUTION:When deuterium ions(D) are implanted into a hydrogen storage metal or alloy such as single crystal palladium, etc. by accelerating energy from 100eV to 1MeV in an ion implanting device, or a discharge tube, or a plasma generating device, the deuterium ions are implanted into the lattice of the single crystal palladium. On the other hand, these deuterium ions are accelerated much more by atoms at lattice points, and thus the stored deuterium atoms or implanted deuterium atoms collide with each other to produce nuclear fusion reaction. The efficiency of generation of thermal energy can thus be extremely increased.

IPC: B24D5/00
Filed: 1984-09-06
Abstract: PURPOSE:To prevent abnormal heat emission during grinding by arranging grinding parts, consisting of grinder element, on a spiral locus at the outside surface of a cylindrical base. CONSTITUTION:If a grinding wheel 10 is rotated with its grinding parts 14 pressed to that surface of a work which shall be processed, the grinding parts 14 draw a spiral locus with rotation, and perform grinding of the surface of work while changing its point of contact with the surface of work. At this time a heat radiating effect is obtained due to the voids at the outside surface of the base where no spiral grinding part 14 exists, and also a cooling effect is given by the coolant which flows from these voids evenly to the processed part. Thus heat emission during grinding is suppressed, and generation of abnormal heat can be prevented.

IPC: H02P29/00
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To control a motor stably, without using any dedicated current sensor at the time of using a high-tension power source. SOLUTION: To rotate motor by fixed angle, the singular velocity of the motor is controlled by means of trapezoidal driving. Targeted velocity V at the time of deceleration is obtained from an expression: V=√2αθ, based on a rotational angle θ until the motor stops and an accurate #' at the time of deceleration, to control the current flowing through the motor. Only the absolute value of current flowing through the motor 11 detected by a sensor 29 to form a loop for current feedback. In a driving direction, a sequential control based on a motor rotational velocity 15 is conducted through trapezoidal driving.  At the time of deceleration, if actual speed 16 is lower than the targeted velocity, motor input voltage set at zero, and at the time of acceleration or constant velocity, of the actual speed is higher than the targeted velocity, motor input voltage is set at zero. Motor current is prevented from reversing against the controlling sequence. Therefore, it is possible to conduct to current feedback stably, even which using a high voltage power source.
