Title: Servo track writing method and servo track writing apparatus
Inventor: FUKUSHI MASANORI
IPC: G11B5/55
Filed: 1998-07-03
Abstract: PROBLEM TO BE SOLVED: To shorten the write time of servo track signal by shortening the positioning time of internal actuator and improve writing quality of servo track signal by reducing vibration of the internal actuator. SOLUTION: In the servo track writing method for recording a servo track signal by utilizing a magnetic head, a first control means 70 defines the position of an internal actuator 56 when the magnetic head 54 is located at the target position as the moving target position Y0 to move an external actuator 60. A second control means 12 obtains, with an adder 14, the current position of the internal actuator 56 from displacement X1 and the current position Y of the external actuator 60. Moreover, a first deviation X2 between the moving target position Y0 and the current position Z is obtained and movement of internal actuator 56 is controlled so that the first deviation X2 is within the reference range and the internal actuator 56 is positioned to the moving target position Y0.

Title: Method and apparatus for timing phase control
Inventor: KOKURIYOU GAROU
IPC: H03K5/1536
Filed: 1981-11-27
Abstract: PURPOSE:To obtain a desired timing phase control without increasing frequency, by shifting in phase a timing signal component picked up from a reception signal, and detecting a zero cross point to coincide it with the timing signal. CONSTITUTION:An output signal Xn from a timing signal component pickup circuit 5 is partly multiplied with a constant k1 at a multiplier 17, and a part of an output signal Xn+1 is delayed at a delay element 18 having a delay time T equal to the sampling period, and then multiplied with a constant k2 at a multiplier 20. Each multiplication output is applied to an adder 19, and its output Yn attains to a signal shifting in phase a timing pickup component by phi. Thus, the phase control of the sampling timing is executed so as to reduce the output Yn to zero, and the relation between the zero cross point of the timing component of the input signal and the sampling point can be set for the zero cross point at a position where the phase phi can be situated between adjacent sampling  points.

Abstract: PURPOSE:To cause a room temperature to rapidly reach a set temperature even in the case of a presence of high load by a method wherein a value of the load is judged in response to an output frequency of an inverter under a condition in which an indoor temperature is kept substantially constant and then a frequency set value is corrected and an air conditioner is driven. CONSTITUTION:A micro-computer determines a temporary driving frequency corresponding to a temperature difference if an operation frequency correction value Salpha under energization is read and a room temperature Ta is lower than a set temperature Ts. The got temporary driving frequency S' and the corrected value Salpha are added and then an operating frequency Si is given to an inverter 2. A room temperature Ta when a compressor 3 is driven is stored as a past room temperature Ta' and then the operation is started. If the room temperature Ta is lower than the set temperature Ts, a temperature difference is proportionally integrated, thereby the corrected operating frequency Si is given to the inverter 2. An absolute value of a difference between the present room temperature Ta and the past room temperature Ta' is calculated and if this value is less than 1 deg.C, it is judged if a timer T times up or not. In the even that the timer times up, the frequency corrected value Salpha at a subsequent operation is determined in reference to the present frequency Si and then this value is stored and an initial operating frequency Si is determined on the basis of this value in the next operation.
