Title: Magneto-resistance effect type magnetic head
Inventor: OKUDA HIROYUKI
IPC: G11B5/39
Filed: 1985-04-17
Abstract: PURPOSE:To obtain a linear response property highly sensitive to signal magnetic flux with a simple structure by inclining the lengthwise direction of an MR element to the lenthwise direction of a slit and making the direction of the shortest distance connecting both conductor junctions provided to both end parts in the lengthwise direction of the MR element to coincide with the lengthwise direction of the slit. CONSTITUTION:The stripe length of an MR element 7 is arranged obliquely to the lengthwise direction of a slit 6 of a magnetic yoke and the shortest- distance direction connecting both conductor junctions 7a and 7b provided to both end parts of the MR element 7 in the lengthwise direction are made to coincide with the lengthwise direction of the slit 6. Since the magnetization in the MR element 7 is already inclined to the lengthwise direction of the slit 6 of the magnetic yoke, a resistance detecting current flows in the direction of the shortest distance connecting both lead wire junctions of the MR element 7. Consequently, when an auto-bias magnetic field is impressed in the widthwise direction of the slit 6 of the magnetic yoke, the magnetization in the MR element 7 is further inclined and the angle formed with the resistance detecting electric current is made to be 45 deg. only by the auto-bias effect.

Title: Position adjuster of cylindrical lens
Inventor: UMEZAWA MICHIO
IPC: G02B7/00
Filed: 1978-07-07
Abstract: PURPOSE:To obtain an inexpensive and easy-to-adjust cylindrical lens position adjuster by using eccentric rings for position adjusting of a holder. CONSTITUTION:To perform position adjustment of a cylindrical lens 9, the position is aligned by slightly loosening stepped screws 12 and rotating eccentric rings 11. At this time, the right and left rings must be turned at the same angle, but if angle scales are inscribed to the flange parts 12 of the eccentric rings 11 and marks are put on the holder 10 side, then turning by approximately the same quantity may be accomplished. Turning the eccentric rings 11 causes a holder 10 to move in both directions of the optical axis direction and the direction rectangular to the optical axis. The lens having been moved parallelly and adjusted to a desired position in this way is fixed to the holder 10 by retightening the stepped screws 12. Thus, the inexpensive and easy-to-adjust cylindrical lens position adjuster may be obtained.

Abstract: PURPOSE: To let incident information light be reflected in the indicent face direction by a reflecting face then be totally reflected and make it emittable toward the exit face by using the subprism of the specified shape.  
     CONSTITUTION: Information light from information 1 incident to an incident face 8 by a subprism 6 assuming the specified shape is reflected in the face 8 direction by a reflecting face 9. A reflecting film is formed on the portion of the face 8 which receives this reflected light or light enters the same from the direction causing total reflection and therefore the reflected light totally reflects on the face 8 and emits toward an exit face 10.

Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To prevent confirmation time from being prolonged or the completion of positioning from being erroneous discriminated when there are residual vibrations in the case of discriminating the positioning completion of mobile body. SOLUTION: During the move of mobile body 18, the position deviation of mobile body is detected at prescribed time intervals by an interferrometer 20 and a differentiator 12, and a positioning completion discriminator 22 calculates statistic quantity (such as standard deviation, for example), defined by using the difference between (m) (n>=m) pieces of detected values among (n) pieces of detected values and the average value of (m) pieces of detected values and calculates the rate of timewise change in that calculated statistic quantity.  Then, the positioning completion discriminator 22 compares the calculated statistic quantity and the rate of timewise change of that statistic quantity with prescribed discrimination reference values and at the time point when the statis quantity and the rate of its timewise change are turned within the prescribed discrimination reference values, it is discriminated that the position of mobile body 18 is sufficiently converged at the target position.

IPC: G03F7/20
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of the distortion of a pattern image projected upon a sensitive substrate due to the local temperature rise of a mask. SOLUTION: At the time of performing scanning exposure, an irradiated area IA on a mask R is irradiated with light IL and the other area than the area IA of the mask R is irradiated with light rays from an irradiating optical system 14, 15, and 16. The energy of the irradiating light projected upon the area IA is measured by means of a sensor 11 and that of the light rays projected upon the mask R from the optical system 14, 15, and 16 is measured by means of another sensor 17. The optical system 14, 15, and 16 is controlled by means of an exposure control unit 12 and a main CPU 13 based on the measured values of the sensors 11 and 17. Therefore, the distortion of a pattern image projected upon a wafer W can be suppressed, because the occurrence of a local temperature rise in the irradiated area of the mask is suppressed.
