IPC: H01L21/68
Filed: 1987-05-29
Abstract: PURPOSE:To make it possible to detect the existence of a wafer with good precison and in a non-contact state by a method wherein light-projecting means, which respectively irradiate on optical beam and irradiate a pair of optical beams in total, and light-receiving means, which receive reflected lights from incident points to output a significant conversion electrical signal to show the existence of the wafer, are provided at respective two points, the distances between which respectively become longer than the distance between both ends in the peripheral direction of the noncircular contour part of the wafer. CONSTITUTION:Optical beams on the side of radiation, which irradiate the peripheral edge part of a wafer 10 which is an existence detecting object, are set in two beams. Respective radiant light beams BR-1 and BR-2 are each obtained from individual projectors 61 and 62 for exclusive use to each beam, while the radiant light beams are set in such a way that a distance L1 between the incident points of the radiant light beams becomes longer than a distance L2 between both ends of a noncircular contour part 11 at points where the radiant light beams are incided in the peripheral edge part of the wafer 10. In case any of the radiant light beams BR-1 and BR-2 is incided in the circular contour part of the wafer 10, it is reflected in the direction of a reflection angle thetaC equal to an angle of incidence thetaC. For this, separate and independent light-receiving devices 71 and 72 are respectively arranged in these paths. Accordingly, the reflected light beams are respective by detected by the light-receiving devices 71 and 72 and output of a significant quantity of converted electricity is produced, for example.

Title: Frequency reduction system for signal to be modulated by amplitude modulation
Inventor: NAKAMURA SHIYOUZOU
IPC: H04L25/49
Filed: 1979-10-15
Abstract: PURPOSE:To reduce the frequency of a signal to be modulated by reducing the cross frequency of the signal to be modulated to half through processes of addition of subtraction and squaring arithmetic of the signal to be modulated and its unipolar envelope signal and the polarity inversion of signals. CONSTITUTION:From signal to be modulated 1' applied to input terminal 1, envelope extracting circuit 2 extracts unipolar envelope signal 2'. Signal to be modulated 1' and envelope signal 2' are applied to adding circuit 3, which obtains signal 3' whose instantaneous values of amplitude are all positive. This signal is applied to squaring circuit 4 to generate signal 4' similar to a full-wave rectified waveform. The position in time when this signal 4' nears the zero potential is detected and from obtained pulse signal 5', polarity-inverted pulse 6' is obtained. This pulse 6' is applied to polarity inverting circuit 7, which regards as one block the period when signal 4' varies from the zero potential to the next zero potential and inverts its polarity in alternate blocks to obtain signal 7' with both positive and negative polarities. This signal retains information included in the input signal and is reduced to half in the frequency in zero-potential crossing.

Filed: 1985-06-19
Abstract: PURPOSE:To adjust easily and freely an optimum characteristic state to both a disturbance and a target value by correcting virtually a control constant which is adjusted to a disturbance suppressing optimum characteristic, to a follow-up optimum characteristic state against a variation of the target value. CONSTITUTION:A compensation operating part 10 calculates a compensation quantity (a) (s) by executing a compensating operation based on a transfer function H(s) to a target value SV in order to correct equivalently control constants KP, TI and TD which have been adjusted to a disturbance suppressing optimum characteristic, to target value follow-up optimum characteristics KP', TI and TD' with respect to a deviation epsilon which has been generated by a variation of the target value. This compensation quantity is subtracted from an adjusting output (u) from a control operating part 11 by an operating part 12, and its result is supplied as a manipulated variable to a control object 3. By this compensation, the transfer function which has been adjusted to the disturbance suppressing optimum characteristic state is changed virtually to a transfer function C' (s) of the target value follow-up optimum characteristic state with respect to the deviation epsilon. In this way, the constants KP', TI' and TD' can be set by correcting a parameter which can be optimized and adjusted originally against a variation of the target value without changing the constants KP, TI and TD.

Abstract: PURPOSE:To obtain necessary fundamental wave components with high accuracy by providing a direct current rejector which removes direct current components from the output of a photodetector and a harmonic rejector which removes harmonic components of the frequency of a phase modulator. CONSTITUTION:A direct current rejector 17 for removing direct current components and a second-harmonic rejector 18 for removing second harmonic components are provided between a current-voltage converter 7 and a synchronous detector 10. The output from a multiplier 25 in the rejector 18 is controlled to be of the same phase as the second harmonic components from the converter 7. Moreover, the output of the multiplier 25 is controlled to be the same level as the amplitude of the second harmonic components from the converter 7 so that the second harmonic components are removed from the output of a subtractor 21. Accordingly, since the direct current components are removed by the rejector 17 from the output signal of the converter 7, and at the same time, the second harmonic components of the frequency of the phase modulator 8 are removed by the rejector 18, a gain can be large even if the input angular velocity is small.

Filed: 1992-05-26
Abstract: PURPOSE:To restrain the attracting action of a magnetic head and that of a magnetic recording medium by a method wherein a coating layer, whose surface energy is low, is formed on the surface of a slider. CONSTITUTION:A magnetic-head slider face 11 is mirror-polished by using a polishing tape in such a way that its surface roughness in the center line becomes, e.g. 5nm. Thereby, a magnetic-head-slider base body is formed. The slider face 11 is coated with low-molecular polytetrafluoroethylene dissolving Flon 113; an organic-substance coating layer 12 which is composed of a fluoride is formed on the slider surface 11. Thereby, while a state that the surface roughness of the magnetic-head slider face 11 and that of a magnetic-disk surface are made smooth is being kept, the magnetic-head slider surface 11 is denatured by means of the coating layer 12 so that the attraction phenomenon of the magnetic-head slider face and that of the magnetic-disk surface are reduced. Thereby, a magnetic head whose low-levitation stability is excellent and which is suitable for a high-density recording operation is obtained.
