Title: Motor controller
Inventor: TAKAGI MASASHI
IPC: H02P29/00
Filed: 1995-01-19
Abstract: PURPOSE: To restrict torque vibration caused by external noise in steady state by providing a moment of inertia computing element, which varies the set point of moment of inertia in response to the operating state of a motor, thereby enhancing the response characteristics in a transient state. CONSTITUTION: If a motor speed command ω* or the like suddenly fluctuates, then the difference between motor speed ωm and motor speed command ω*increases and exceeds the absolute value of the speed deviation from the output of subtracter 7. At this time, the moment of inertia computing element 9 performs arithmetic operation by inputting the output from the subtracter 7, outputs the result as the set point of the moment of inertia, and inputs said output to an equivalent disturbance compensation computing element 5 and a feed forward computing element 4. By doing this, high speed response characteristics during transient state can be improved and torque vibration caused by external noise in steady state can be restricted.

Inventor: ITO SADAO
IPC: H04W72/08
Filed: 1990-02-03
Abstract: PURPOSE:To reduce transmission output and to effectively use a frequency by taking the number of multiplex for TCM(time division compression multiplex) signal, the time length of one frame and a highest frequency which an original signal has as parameters, and clearly introducing a multiplex load gain through the use of a sampling theorem. CONSTITUTION:The multiplex load gain which the TCM(time division compression multiplex) signal transmitted from a radio base station 30 has is caused to correspond to a multiplex load gain which an FDM(frequency time division multiplex) signal has. Thus, respective sound signals flowing in respective channels CH1, CH2,..., CHn of FDM are expressed in the form of a function. Then, the gain of the multiplex signal is introduced by using the sampling theorem. Thus, a system can be designed so that the multiplex load gain which is substantially the same as that in a case when transmission is executed from the radio base station 30 can be obtained even in a case when a moving radio unit 100 executes transmission and the radio base station 30 executes reception.

Title: Magnetic disk device
Inventor: YONEMITSU SHINOBU
IPC: G11B21/08
Filed: 1987-02-05
Abstract: PURPOSE:To protect a voice coil motor winding by providing a power circuit with a capacitor, which supplies a charged electric charge to the input of a servoamplifier at a first time constant, and with a direct current power circuit, which charges the said capacitor at a second time constant longer than the first time constant. CONSTITUTION:When the start of the voice coil motor occurs frequently, the winding of this motor is overheated and sometimes is burnt out. If the power supply of the servoamplifier 4 to drive the voice coil motor is performed through the capacitor 3, and the time, required for charging it, is made longer than the time required for discharging it, when a discharge is repeated during the short time, the terminal voltage of the capacitor 3 drops lower, and the servoamplifier 4 can not execute a normal operation, and a seek error takes place, and the power is not supplied to the voice coil motor until a restoration operation is completed. Thus, because a condition that the voice coil motor winding 5 is overheated and burnt, is actualized by the seek error accompanied by the voltage drop, the voice coil motor can be protected without necessitating an additional circuit.
