Abstract: PURPOSE:To form the pit of good quality by irradiating with laser light having a power value matched to the shortage of a magnetic field necessary for orienting magnetization to the magnetic field direction while a bias impressed magnetic field is not saturated at the stage of magneto-optical recording. CONSTITUTION:A magneto-optical recording medium 2 is irradiated with the laser light corresponding to an information signal irradiating the magneto-optical recording medium 2 with the power matched to the shortage after detecting the shortage of the magnetic field till the magnetic field fully enough for reversing the magnetized direction of the magneto-optical recording medium 2 is impressed on the magneto-optical recording medium 2. Ordinarily, a semiconductor laser 5 is turned on with fixed light power, but till the magnetic field is saturated after a signal reversal detecting signal S1 is inputted in a light modulation circuit 15 (while a signal S3 is outputted), the laser 5 is turned on with the power value matched to the shortage of the magnetic field. Thus, the pit of good quality can be formed, so that the unstable area of the magnetic field is formed as little as possible and good overwriting can be performed.

Filed: 1990-07-05
Abstract: PURPOSE:To determine plane coordinates of respective measurement points and to obtain the thickness of the tube body by rotating a rotary head and measuring the distance to the tube body surface while a noncontact optical displacement gauge is put opposite the tube body surface. CONSTITUTION:A switch 19 is switched to its measurement-time side and a motor 4b is driven in this state to rotate the rotary head 4, thereby sending a detected value of a radius linear position detector 5e and a detected value of the displacement gauge 5b to multiware 11 each time the rotary head 4 rotates by a fine angle DELTAtheta of rotation. The relative positions of a measuring head 5 and the displacement gauge 5b are fixed, so the coordinates on the external surface of a tube 7 to be measured are determined by the addition and subtraction between the detected value of the linear position detector 5e and the detected value of the displacement gauge 5b. The detected value of the displacement gauge 5b is sent to the multiware 11 through an external displacement gauge display part 15 and also sent to a radius servoamplifier 18 at the same time. This radius servoamplifier 18 controls the driving of a motor 5b according to said detected value so that the value becomes zero, thereby moving the measuring head 5.

Abstract: PURPOSE:To form a position accuracy detection pattern in a manner not to disturb the formation of an element by disposing the position accuracy detection pattern of a line width not resolved when it is exposed by reduction projection on a workpiece in an IC chip effective region of the reticle. CONSTITUTION:A position accuracy detecting pattern 12 formed on a reticle 11 has a line width (a) not resolve when it is transferred to a wafer by reduction projection exposure. Accordingly, when it is transferred onto a wafer 14 by contraction-projecting exposure, the pattern 12 is not imaged. Thus, it is not presented in one chip 15 of the wafer 14. For example, (4X3) pieces of patterns 12 are formed at a pitch of a1=20mm laterally and b1=30mm longitudinally in an IC chip effective region 13. When the (4X3) pieces of the patterns are provided, the positional deviation of the local pattern can be detected over substantially whole IC forming pattern, and the number of the patterns and a disposing method can be suitably selected in response to the shape of the IC forming pattern.

Title: Information processor
Inventor: ENDO TORU
IPC: H04N1/21
Filed: 1989-07-11
Abstract: PURPOSE:To keep the irregularities in an image minimum by generating an internal clock signal synchronizing with a 1st clock signal in the same cycle as an external clock signal, performing the parallel/serial conversion of data based on the signal and correcting the internal clock signal when deviation occurs in an information processor. CONSTITUTION:An internal synchronism circuit 3 is actuated independently of a timing deviation detection circuit 2 and outputs the internal clock signal LDL synchronizing with a dot clock signal DCK in the same cycle as the external clock signal LD from the Q terminal of a 6th flip-flop circuit 12. Based on the clock signal (LDL), the parallel/serial conversion is performed. Meanwhile, at the time of detecting the timing deviation between the external clock signal LD and the dot clock signal DCK, a deviation detection signal CR is outputted from the timing deviation detection circuit 2. Then, the rise of the internal clock signal LDL is forcibly delayed and the signal LDL rises when the deviation is not detected. Thus, the irregularities in the image caused by the timing deviation is kept minimum.
