Title: Controller
Inventor: KOBAYASHI HIROKAZU
IPC: H02P29/00
Filed: 1991-10-08
Abstract: PURPOSE:To prevent torsional shaft vibration smaller than the detecting resolution of speed signal by utilizing a torque meter signal after passing it through a band pass filter. CONSTITUTION:A deviation (e) between a command input R and the output omega(S) of a part of a state variable is given stabilization compensation by a PI controller 1, etc., and its output becomes Tchi(S). The torque command T*(S) is multiplied by a torque generation coefficient KI, and is impressed to a motor 2 by passing it through a power actuator. A feedforward compensating part 4 inputs the set input R, and adds its output to stabilized compensated output. On the other hand, the outputs of an equivalent disturbance compensating part 5 to input the torque command T* (S) and the motor revolving speed omega(S) and the band pass filter 6 to input torque meter output TT/M(S) are added to the stabilized compensated output. Accordingly, follow-up ability for the change of a command and robustness against the variation of load and the variation of a parameter can be secured, and in addition, the steady and small torsional vibration can be prevented.

Abstract: PURPOSE:To freely utilize coating materials contg. various kinds of pigments by providing at least a part of the inner peripheral part, outer peripheral part or intermediate part with a magnetic layer in a broad link form and providing label printing layer of characters, graphics, etc., in the remaining part. CONSTITUTION:This information recording medium is so constituted that a magnetic head 7 for video recording comes into direct contact with the magnetic layer 5. The magnetic recording layer 5 has heretofore a four-layered coating film structure which consists of the magnetic layer/concealing layer/printing protective layer. The head for video recording is so formed as to come into contact with the printing protective layer. There is no spacing loss for the three-layered components described above in this information recording medium and, therefore, the electromagnetic conversion characteristics become exceedingly advantageous. Multicolor printing is easy in the case of film formation by screen printing and the coating material for the magnetic layer and the coating material for the label printing layer are merely necessitated to be prepd. as the separate coating materials. Namely, the coating materials contg. various kinds of the pigments are freely usable as the coating material of the label printing layer.

IPC: G06F17/50
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To reduce power consumption without enlarging skew by distributing registers to plural partial trees, so that the number of the same registers becomes large in a register transfer condition, forming a clock tree and setting the enable logic of the partial trees, where the registers are distributed to be the sum set of the register transfer condition of respective clusters. SOLUTION: A clock tree is formed as the set of partial trees T0 to T4. A clock CLK is inputted to one input of AND elements G0 to G4 through a buffer 11. Enable logics En(T9) to En(T4) controlling the opening/closing of the AND elements are inputted to the other input terminal of the elements. When the enable logics are realized, the clock CLK is supplied to the partial trees T0 to T4 through the AND elements. When the AND elements G0 to G4 are gated, the enable logic becomes OR of the register transfer condition of a register group allocated to the partial tree.

Title: Y/c separation circuit
Inventor: OGOSHI TAKASHI
IPC: H04N9/78
Filed: 1989-10-06
Abstract: PURPOSE:To evade the deterioration of image resolution by outputting only a chroma signal from an input video signal, using a clock signal with a frequency that is four times its chrominance sub-carrier signal. CONSTITUTION:An input video signal SV is given to a clock signal preparation circuit 4 through an automatic phase adjustment circuit APC. The circuit 4 makes the burst signal of the signal SV synchronous, and prepares a clock signal CK1 with four times the frequency of the chrominance sub-carrier signal of the signal SV. And, an analog digital conversion circuit 6 quantizes the clock signal CK1 of the signal SV, and outputs this to a three-dimensional chroma signal separation circuit 8. The circuit 8 separates the output signal of the circuit 6 into the chroma signal and a luminance signal, and outputs only the chroma signal. Further, the chroma signal is subtracted from the signal SV at a subtraction circuit 18 and separates the luminance signal, so the deterioration of the image resolution can be evaded effectively without making the constitution large and complicated.

Filed: 1995-10-09
Abstract: PROBLEM TO BE SOLVED: To record with a low rate of error occurrence according to the number of pieces of the binary data to be recorded and to precisely reproduce the binary data. SOLUTION: The binary data by one bit are recorded at one recording period TT. At this time, before the binary data are recorded on a magnetic recording track 35, the number of pieces of the binary data to be recorded are studied, and the more recording density is set in high, the more the number of pieces are large, and when the number of pieces of the binary data are less, the recording density is set in the low recording density with the low rate of error occurrence. Then, at a magnetic recording time, one recording period TT it decided according to the set recording density and a feeding speed of a film, and for preventing a data signal and a clock signal at a reproducing time from exceeding to approach, the more the recording density is increased, a data pulse position is made so as to approach to 50%, and an (N magnetization area) and an (S magnetization area) are recorded by a data pulse and a clock pulse. Further, for vibrating the data signal and the clock signal at a prescribed amplitude at the reproducing time, the magnetization area of the side recorded shortly among respective magnetization areas is recorded so as to become a fixed level regardless of the recording density.
