Title: Magnetic head grinding device
Inventor: HISADA TAKAYOSHI
IPC: B24B5/313
Filed: 1986-05-19
Abstract: PURPOSE:To easily and securely remove a head from a jig by turning at a low speed the rotary jig main body which returns to a home position after completing a grinding operation, and fixing the rotary jig on a prescribed turn position with the groove part of a flange and a lock member. CONSTITUTION:The head fitted to the rotary jig main body which is shifted to a rough grinding position by an electrically driven shaft 2a and turns at a high speed is grinded by a rough grinding shape. Then the rotary jig main body is shifted to a fine grinding position, and fine grinding is executed similarly. When these grindings are completed, the rotary jig main body shifts and returns to the home position. Then the rotary jig main body is switched to a low-speed turn, and it always stops in a correct position required through the engagement between the groove part 47 provided din the frange part 41 which turns integrally with the rotary jig main body and the lock member 49, whereby a lock to the rotary jig main body is released by air drivings, and the removal of the grinded head is executed securely and easily. As a result, the work of the head grinding can be automated by the use of a robot.

Filed: 1994-04-28
Abstract: PURPOSE:To improve the accuracy of focus adjustment by inverting a correction direction of a focal face by a variable power lens at the start of variable power operation to a prescribed correction direction. CONSTITUTION:Drivers 117, 119 sets a phase of an exciting phase of a 4-phase motor to a forward phase rotation and reverse phase rotation depending on a phase rotation signal and output a signal while changing an applied voltage of a motor exciting phase depending on the received rotation frequency signal to turn on/off an output to motors 118, 120 while controlling the rotating direction and the rotating frequency of the motors 118, 120. When an inching zooming is repeated, that is, zooming is repeated momentarily such as telescopic drive/ stop, since a direction of focal point correction is set to an infinity at first, a defect of a conventional camera becoming unsharp gradually in the infinite direction is eliminated. Furthermore, the deterioration in the focus detection accuracy by zooming is prevented and the focus is adjusted with high precision at all times.

IPC: H01S5/00
Filed: 1978-09-18
Abstract: PURPOSE:To reduce the rise on the IC wafer when processed by providing a multimode light fiber betwen the laser oscillator and the object lens for processing. CONSTITUTION:Since the laser oscillator 1 performs a multiplex transverse mode oscillation, its intensity distribution is a Gaussian distribution the foot of which is long, and the roundness of the laser beam is not good. Such a beam is condensed by the use of a convex lens 2, and is introduced to the multimode light fiber 3. When the laser beam passes through the fiber, the mode is transformed, the intensity distribution at the exit becomes a trapezoidal distribution which is determined by the fiber refractive index distribution. The shape of beam, which is determined by the shape of core, is a circle with a good roundness. When the beam is condensed on the surface of wafer 4 through the object lens 7 to process the wafer, a processed piece without a rise of melting portion can be obtained.

Title: Liquid level detector using refraction of light
Inventor: SAITO TEI
IPC: G01F23/28
Filed: 1987-05-13
Abstract: PURPOSE:To detect the level of liquid which is extremely inferior in electric conductivity and transparent by passing projection light the container side walls of a projector side or/and a photodetector side. CONSTITUTION:The projector 2 and photodetector 3 are arranged opposite the same height parts of both sides of a transparent cylindrical container 1 so that lines (a) and (e) connecting both do not run in the center of the circle of the cylinder. Then when the container 1 does not contain a specific amount of liquid, namely, when the liquid level is lower than the liquid level [dotted line (c)], light projected by the projector 2 is not refracted and travels straight to reach the photodetector 3. When the liquid level is higher than the line (e) [dotted line (d)], on the other hand, the projection light is refracted when entering (point A) the liquid and exiting (point B) from the liquid to travel as shown a dotted polygonal line (b), and never reaches the photodetector 3. For the purpose, variation in the quantity of the light reaching the photodetector 3 is detected electrically to detect whether or not the container 1 contains a specific amount of liquid, and consequently an ultrasonic wave transmitter is turned on and off without any trouble.
