Title: Offtrack correcting method for disk device
IPC: G11B5/596
Filed: 1992-03-31
Abstract: PURPOSE:To shorten a response time and to perform an accurate correction by reading and measuring a pair of servo data, obtaining a conversion coefficient G by using the measured value, and thereby performing an offtrack correction with the value calibrated by the conversion coefficient G. CONSTITUTION:In an offtrack correction section 7, the offtrack data from a read/write control section 3, offtrack correction data with the input of head numbers from a host controller, and ontrack slider data are generated. A head positioning servo control section 5 inputs the servo signal read by a servo head 12 and the offtrack correction data or the like from the offtrack correction section 7, a head positioning servo control is performed by receiving commands from the host controller. The conversion coefficient G is stored in a nonvolatile memory 38A. At the time of executing calibration, the offtrack correction data is calibrated by means of the conversion coefficient G. Thus, the offtrack correction always accurate in the environmental change and the temperature change can be performed in a short time.

Title: Control equipment of motor
Inventor: SHIMATANI KEISUKE
IPC: H02H7/08
Filed: 1996-03-29
Abstract: PROBLEM TO BE SOLVED: To simplify structure and improve incorporation work, by making it possible to heat refrigerator oil without installing a crank case heater. SOLUTION: This control equipment converts electric power supplied from a power source PS to specified controlled three-phase AC power, outputs it to an induction motor CM, pulse-width-modulates the supply voltage to the induction motor CM, and controls a power converter circuit 20 in such a manner that the induction motor CM is subjected to variable speed control. On the other hand, when a preheating signal is receive during halt of the induction motor CM, the control equipment outputs one phase supply voltage out of the supply voltage to the induction motor CM, as a pulse-width-modulated voltage signal, to the induction motor CM, and outputs the other two-phase supply voltage, as a continuous voltage signal of the same phase square wave AC which is not pulse-width-modulated and held at a specified voltage, to the induction motor CM.  As a result, heat is generated without rotating the induction motor CM.

Abstract: PURPOSE:To enable communication from the beginning even by a newly registered telephone number by copying corresponding information to the telephone number registered before at the time when the telephone number is registered newly. CONSTITUTION:When the telephone number is registered newly to a one-easy- step/abbreviated dial, a CPU 1 calculates the SUN value of the registered telephone number, and stores this SUN value and the telephone number in the telephone number storage area of a RAM 2, and simultaneously, it compares it with the SUN value of the registered telephone number stored before in the telephone number storage area and a redial number storage area. Then, when these two SUN values coincide with each other, it compares next all the digits of the registered telephone number with all the digits of the newly registered telephone number, and if they coincide, it discriminates whether there is additional information corresponding to the registered telephone number in an additional information storage area or not. Then, in the case that communication was executed before by the registered telephone number and there is the additional information, it copies the said additional information to an additional storage area corresponding to the new registered telephone number.

IPC: G03F1/84
Filed: 1995-04-03
Abstract: PURPOSE: To obtain a measuring apparatus by which the phase, the amplitude transmittance and the energy transmittance of a photomask can be actually measured simply and precisely by a method wherein parallel light from a light source for measurement is converted into beams of linearly polarized light whose polarization directions are orthogonal and which advance to different directions. CONSTITUTION: Out of beams from a light source 202 for measurement, a beam (parallel light) which is passed through a beam splitter 210 and the advance direction of which is then bent by 90 deg. by a beam splitter 204 is used for a measurement. The beam is made incident on the Wollaston prism 205 so as to be converted into two beams of linearly polarized light whose polarization directions are orthogonal and which advance to different directions. The two beams of linearly polarized light are condensed in different positions on a photomask 208, and they are then converted into parallel light so as to be superposed.  Since the two beams of linearly polarized light reflect the optical property in the part of the photomask 208 which has been transmitted, it is possible to detect various relative characteristics between two different points on the photomask 208 by the polarization state of superposed light.

IPC: B22D11/16
Filed: 1978-06-27
Abstract: PURPOSE: To let stable controlling be effected for rapidly fluctuating molten steel levels by controlling the openings of sliding nozzles by the signals having integrated the differential signals between the molten metal level setting signals and molten metal level input signals.  
     CONSTITUTION: Temperature detecting sensors T 1 ... are buried at an equal spacing in a casting mold 8. Their detection signals enter a gate pulse generating circuit 6a and the gate pulse signals enter a gate control circuit 6b. Here, they are converted to the input-signal-selecting gate signals G 1 ... which then enter an input signal selecting circuit 6c. Set signals S 1 ...S n  through resistances R 11 ...R n  from a reference voltage e 2  enter a set signal selecting circuit 6d. The set signal selecting circuit 6d allows the passage of only the S m  out of the set signals S 1 ...S n  according to the set-signal-selecting gate signal C m . The outputs of the circuits 6c and 6d enter an operational amplifier OA. The output e 0  of the operational amplifier OA is the one which has smoothed the deviation between the set level and detected level, thus even if the detected level fluctuates owing to waving phenomenon or the like, the control output to be applied to a hydraulic control unit 5 becomes stable one.

Abstract: PURPOSE:To improve safety, by a method wherein, in a title device, e.g. a portable kerosene stove, the lower end of the suction part of a wick is raised to a level higher than that of the fuel oil level through the force of a spring made of a shape memory alloy under a weight when atmospheric temperature increases to a given value or more. CONSTITUTION:At an ordinary atmospheric temperature, the lower end 4a of a wick 4 is immersed under the oil surface 1a in a fuel tank 1 in a way that it is stretched through the force of a safe spring 11 made of a shape memory alloy 12 under a weight 12. When atmospheric temperature increases to a value higher than the actuating temperature of the shape memory alloy, the safe spring 11 shrinks to lift the lower end 4a of the wick 4 upward from the fuel oil level 1a to stop suction of fuel. Thus, combustion is stopped to improve safety.
