Abstract: PURPOSE:To prevent lapping compound gas from being admitted into a bearing section from a working chamber by forming an isolated chamber between the bearing section supporting moving members such as a surface plate and the like, and the working chamber whereby keeping the internal pressure thereof higher than the internal pressure of the working chamber. CONSTITUTION:A work is placed on a surface plate 4 so as to be pressed by a jig 30 which is moved down by a cylinder 31, via a block wherein the surface plate 4 is rotated by a motor 12 via a change gear 11 whereby performing a lapping work. And air from an air source 29 is injected into an isolated chamber 26 provided to the sealing section of a bearing section 18 supporting the surface plate 4 so as to be fed into the internal isolated chamber 33a of a pressurizing mechanism 5 in order to be injected into an external isolated chamber 33b through an outlet port. Volumetric change accompanied by the elevation of the jig 30 is absorbed by air supply whereby the internal pressure of the isolated chambers 26, 33a, 33b is kept higher than the internal pressure of a working chamber 2. Accordingly, lapping compound gas is not admitted into the surface plate 4 and the bearing section of the jig 30 for preventing corrosion.

IPC: H02K11/00
Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To generate index pulses with stable signal-to-noise ratio and make it possible to cope with thresholds on both sides, by installing a magnetic substance for converging magnetic fields behind a surface mount-type ferromagnetic orthogonal magnetic resistance element placed on a stator board. SOLUTION: A surface mount-type ferromagnetic orthogonal magnetic resistance element (orthogonal MR element) as a magnetic sensor 7, is installed on a stator board 8 opposite to a single-pole index magnet 6 installed outside a rotor. Thus, a rotation signal generator is constituted which detects magnetic fields from the index magnet 6, rotated integrally with the rotor, through the orthogonal MR element and generates rotation signals. A magnetic substance 9 for converging magnetic fields is installed behind the orthogonal MR element placed on the stator board 8. This increases effective magnetic flux detected by the orthogonal MR element to enhance signal-to-noise ratio, and obtains an accurate rotation signal generator suitable for spindle motors for driving magnetic disks.

Abstract: PURPOSE:To improve both efficiency and accuracy for surface grinding of a disc shaped work by feeding a cup shaped grinding stone, the rotating shaft of which is parallel with that of a table mentioned later on, to the radial direction against a work coaxially fixed on the rotating table as a whole in such a way that the depth of cut is made when the same reaches the center thereof. CONSTITUTION:Toward a wafer 3 coaxially mounted on a turning table 4, a cup shaped grinding stone 1 which has a rotating shaft in parallel with that of said table while being held movably up and down to the right and left directions, is lowered down in such a way that a machining allowance from the time of grinding start will be (t1) so as to perform the creep feed grinding with a feed provided to the left direction. And when the grinding stone 1 reaches the center of rotation, a depth of cut (t2) is made, then the grinding stone 1 is lifted up after grinding is over. Accordingly, grinding up-to the machining allowance (t1) can be accomplished for a short period of time only by moving the grinding stone to the center of the wafer, and furthermore grinding is performed while the machining allowance (t2) enables a positional relation between the grinding stone 1 and the wafer 3 to be kept constant thereby providing the satisfactory accuracy of surface shape.

Title: Controller

IPC: G05D13/62
Filed: 1987-04-30
Abstract: PURPOSE:To surely apply control with simple constitution, by switching a control direction by a speed change detecting output in the turntable of a record player, etc. CONSTITUTION:A signal with a frequency proportional to the rotating speed of the turntable 1 is outputted from a head 2, and is converted to a voltage V at a frequency- voltage converter 3. The voltage V is compared with reference potential at a differential amplifier 4, and a driving motor 6 is servo-controlled via a power amplifier 5. When the table 1 is rotated reversely by a manual operation and rotating speed becomes less than reference rotating speed, the output of the amplifier 4 goes to a negative value, and the motor 6 is turned in a direction opposite to the same direction of manual turning, thereby, erroneous brake is applied. Then, the inversion of the output of the amplifier 4 to the negative value is detected by a comparator 9, and also, the output of an acceleration detector 7 goes to a positive value, and an FF11 is set via an AND circuit 10, then, the output of an amplifier 5 goes to 0 or the positive value, thereby, the erroneous acceleration of the motor 6 can be prevented from being generated. In such a way, it is possible to apply turning control surely with the simple constitution without necessitating the detection of a turning direction.

Filed: 1988-05-02
Abstract: PURPOSE:To observe an object in two states where adopting focal distances are largely different from each other by using a retro-focusing type object lens for endoscope composed of a front-group diverging lens system and rear-group converging lens system and moving the rear-group lens system so as to satisfy a specific condition while the front-group lens system is fixed. CONSTITUTION:Variable power setting and focusing are simultaneously performed by moving the converging lens group along the optical axis so that the magnification of the converging lens group can satisfy the condition of inequality I. The Bzr' and Bzw' of the inequality respectively represent the magnification of the rear-group converging lens system when an object can be observed under the best condition in the long- focus state of the two states of the long- and a short-focus states and the magnification of the lens system when an object can be observed under the best condition in the short-focus state. Therefore, an object can be observed in two states, with the object being observed with an appropriate depth of field at a wide angle of field in one state and being observed in an enlarged state while a distance is maintained between the observer and object in the other state, with a simply constituted object lens of two or three groups and a certain diagnosis can be performed in short time by searching a change to a morbid state and observing the change in the enlarged state.
