Title: Magnetic data processor
Inventor: SEZAI HIDESHI
IPC: G07B11/02
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce the rate of the occurrence of a defective reading of an information recording medium by setting the slice level of a recording of magnetic data at a first time separately from the slice level of the reading of the data at a second time. SOLUTION: Reading signals, which are extracted from magnetic data recorded on an information recording medium through a magnetic head, are read using a prescribed slice level. Then, a prescribed arithmetic processing is conducted based on the read data and the new data, which are the results of the processing, are written into the medium. In order to check whether the written magnetic data are normally written or not, the reading signals extracted through the head are reread using the prescribed slice level. Note that the slice level used in the reading of the magnetic data at the first time is set separately from the slice level of the reading of the magnetic data at the second time.

Title: Device for controlling state of other motor in accordance with rotating state of one motor
Inventor: SUNAOKA SEIICHI
IPC: H02P5/51
Filed: 1979-02-16
Abstract: PURPOSE: To smoothly operate a winding machine and reduce the size of a device for controlling the state of other motor by the rotating state of one motor by employing the first motor and the second motor having smaller inertia than that of the first motor to control the second motor drive according to the first motor state.  
     CONSTITUTION: The bobbin 1 of a winding machine or the like is axially rotated by the first motor 15, and axially reciprotated by the second motor 8. The rotating states of the motors 15, 8 are applied through pulse output means 7, 10, respectively to counter circuits 22, 23, respectively. A comparator 24 compares the counted value of the counter 22 with that of the counter 23 to control the drive circuit 29 and brake means 31 of the motor 8. When the counted value of the counter 22 is larger than that of the counter 23, the motor 8 is driven through the drive circuit 29. When the counted value of the counter 22 is lower than that of the counter 23, the motor 8 is braked through the braking means 31 to decelerate the motor 8. Thus, the winding machine can be smoothly operated to reduce the size of the control circuit.

Title: Substrate holding hand
Inventor: TSUCHIDA HITOSHI
IPC: H01L21/68
Filed: 1989-01-27
Abstract: PURPOSE:To avoid the falling-off of a substrate from a holding hand and hold and carry the substrate safely by a method wherein, when a detection mechanism detects the decline of an attracting pressure, a second substrate support member is moved to the substrate side and the substrate (wafer) is held between a first substrate support member and the second substrate support member. CONSTITUTION:A wafer 3 is held by the wafer rear support member 4 of a wafer hand and carried to a next stage. If the attraction failure occurs in this state, a vacuum degree in a vacuum hole 12 is declined and a vacuum-off signal is transmitted from a vacuum switch 8 to a CPU 13 and the core 10 of a solenoid 9 is moved and removed from a hole 11. Therefore, a wafer surface support member 6 is moved to the direction of an arrow B by the relief of a spring board force. A wafer surface contact member 7 touches the surface of the wafer 3 and the wafer 3 is held between the wafer surface contact member 7 and a wafer rear support member 4 to protect the wafer 3 from falling-off. With this constitution, the falling-off of the substrate can be avoided and sufficient safety can be maintained while the substrate is carried.

Abstract: PURPOSE:To eliminate double typing of a character, namely, the so-called ghost from occurring, by providing an intermediate member and an elastic member for transmitting the rotation of a rotary sliding member to a type bar piece. CONSTITUTION:A rotational motion of a printing arm is transmitted through a shaft 16, the rotary sliding member 21, a projected part 32, the elastic member 33 and the intermediate part 30 to a projected part of the type bar piece 26, whereby the type bar piece 26 is set into a circular motion to rotate a type bar 2 by an angle beta suitable for printing. In this case, although a type 58 and a printing surface of a platen 3 are set to be spaced from each othr by an appropriate distance delta, the type bar 2 continues the rotational motion while deforming the elastic member 33 under inertia, and the type 58 collides against the platen 3. In this case, since the type 58 is securely made to collide against the platen 3 only once even when a little chattering exists between the shaft 16 and the sliding member 21, it is possible to print sharply and to prevent the so- called ghost from occurring.

Abstract: PURPOSE:To prevent the formation of an eave section by a method wherein an upper layer film is etched, a resist is softened, an opening circumferential edge is coated, and lower layer films are etched when the films having different quality are coated with the same resist mask and etched. CONSTITUTION:An SiO2 thin-film 22 and poly Si 23 are piled up on an Si substrate 21, and oxidized in wet types and an SiO2 thick film 24 is made up.

Abstract: PURPOSE:To enhance supporting rigidity, and to secure the support in the thrust direction by providing a wall being integral with a casing between a first output disk and a second output disk, and providing bearings for supporting the loads both in the thrust direction and in the radial direction between the above wall and the first and second output disk. CONSTITUTION:By the engagement of a driving gear 55 with a driven gear 60, a force in the radial direction acts on a sleeve 54, and also a force in the thrust direction is caused. Both the radial force and the thrust force acting on the sleeve 54 are supported by angular ball bearings 57 and 58. Accordingly, an input shaft 38 is not deformed so much, and the driving gear 55 is prevented from being inclined or being deformed in its central position, thus the specified engaging state can be maintained. Further, since the support in the thrust direction can be also given by angular ball bearings 57 and 58, the position in the axial direction of a first continuously variable transmission mechanism 22 and a second continuously variable transmission mechanism 24 can be securely regulated, and a stable operation can be obtained.
