Title: Method and device for fault detection of servo system
Inventor: HANADA TAKESHI
IPC: G05B9/02
Filed: 1980-11-26
Abstract: PURPOSE:To detect a fault with probability even in case when a command value is consecutively given, by calculating the absolute value of the deviation between the command value and the feedback value and deciding the fault of a servo system from the result of the above-mentioned calculation. CONSTITUTION:The command value (a) is applied from a command means 1 in the form of the level of the DC voltage. While the position displacement of a control subject 2 is detected by a detecting means 3 to obtain a DC signal (b) in accordance with the position displacement. The deviation value (c) between the value (a) and the signal (b) is obtained through an arithmetic part 4. Then a servo amplifier 5 controls a hydraulic servo valve 6 with the signal (b). The valve 6 controls the oil flow rate (e) to be supplied to a hydraulic cylinder 8 and then controls the position displacement (c) of the control subject. The absolute value of the deviation signal (c) is monitored by a servo system fault detection element 9. When a fault is detected for the servo system, a signal (f) is transmitted to immediately stop the operation of a hydraulic source 7.

Filed: 1986-07-15
Abstract: PURPOSE:To suppress the rocking of a tracking actuator at the time of rough accessing by providing one or more coils of approximately rectangular forms around an objective lens holding barrel and supplying the direct currents to those coils. CONSTITUTION:An objective lens 2, a focusing coil 3, and a tracking coil 4 are attached to an objective lens holding barrel 1 which is revolved and slided by a support shaft 9. While the track neutral position locking coils 11 are attached to two neutral positions where the direct currents flow to a linear effective part at the same level and in the directions opposite to each other. The barrel 1 is set at the center of a magnetic gap of a focusing/tracking magnetic circuit 8. When the barrel 1 is shifted from the center position of a track, the different levels of magnetic flux density are applied to two linear effective parts. Then a difference is produced between levels of the magnetic force produced at a coil effective part. Based on this difference, the barrel 1 is moved back to the track neutral position and locked there.

IPC: F15B9/09
Filed: 1983-09-09
Abstract: PURPOSE:To prevent impact at stopping and to increase repetitional precision by decelerating a piston under control through actuation of a cavity-type electromagnetic brake when the piston reaches the braking start position. CONSTITUTION:A cavity-type electromagnetic brake 8 is attached to a head cover 7, enclosing the projecting portion of a ball screw 5, and a rotary digital signal generator 9 is mounted to the outmost end of the ball screw 5. An arithmetic unit 10 receives outputs from the rotary digital signal generator 9 and a desired position setting unit 11, and the output from the arithmetic unit 10 is fed to a cavity-type electromagnetic brake controller 15. When a piston rod 3 reaches the braking start position, a braking start signal is fed from the arithmetic unit 10 to the brake controller 15 to apply braking force to the ball screw 5, and thereby to decelerate the piston 2. Thus, the piston rod 3 of a pneumatic cylinder can be stopped at high precision with no impact.

Title: Apparatus for separating and removing different kind of glass
Inventor: TANAKA HIROSHI
IPC: C03B5/20
Filed: 1986-07-17
Abstract: PURPOSE:To improve the quality of molten glass, by placing a detachable weir in a clarifier and attaching a protrusion to a spout to prevent the displacement of the weir, thereby separating different kind of glass and surely preventing the mixing of the different glass. CONSTITUTION:Molten glass 3 is held in a temperature-conditioning clarifier 1 connected to a glass smelting tank and is transferred from the clarifier 1 to a forming apparatus via a spout 2. A detachable weir 6 made of refractory is attached to the clarifier-side of a part near the connecting part of the clarifier 1 and the spout 2 and a protrusion to prevent the displacement of the weir 6 is placed at the spout-side. The weir 6 blocks the flow of the different kind of glass having relatively high specific gravity compared with base glass and generated in the glass-smelting process and retains the glass in the clarifier 1. Since the weir 6 is supported by the protrusion 7, there occurs no displacement of the weir. Only high-quality molten glass is flowed into the spout 2 by the above structure to enable the supply of high-quality molten glass to a forming apparatus.

Patent JP-S6227162-A (JP)
Title: Recorder
Inventor: ISHIKAWA TADASHI
IPC: B41J2/01
Filed: 1985-07-30
Abstract: PURPOSE:To prevent printing from being conducted when a recording medium is misset face side back, by providing a means for detecting whether or not the surface of a recording medium is coated with a UV absorber, and discriminating the face side and the back side of the recording medium on the basis of an output from the detecting means. CONSTITUTION:When a recording paper P is misset face side back and is fed in that state, the surface of the paper coated with an ink absorber is disposed on the side of a UV ray detecting means 20. Therefore, a light component in a UV region of the light emitted from a light emitter is absorbed by a UV absorber incorporated in the ink absorber, so that the light component does not reach a light receiver as reflected light, and UV rays are not detected, resulting in that an output signal at this time is maintained at, for example, a 'Low' level. On detection of the arrival of the recording paper by a paper sensor 16, when the output signal from the detecting means 20 is inverted to 'High', a recording operation is carried out following a predetermined sequence. When the output signal remains 'Low', it is judged that the recording paper is misset face side back or the paper is absent, and the next operation is not conducted. The operation of the recorder is stopped, for example, after reversely feeding the paper.
