摘要： An in-line type magnetic head supporting apparatus of the present invention including a first fixed part secured to a magnetic head slider mounted with a magnetic head in a floatable manner, a second fixed part secured to a load beam which presses the magnetic head slider toward the magnetic disc, and a gimbal mechanism comprising a spring part connecting the first and second fixed parts and enabling the pitching and rolling movements of the magnetic head slider in the radial direction of the magnetic disc, and further includes a restricting mechanism for preventing the sideslip of a pivot formed on the first fixed part as a fulcrum for pitching and rolling movements. Furthermore, in order to increase the flexural rigidity of the spring part of the gimbal mechanism in the radial direction, its lateral length is enlarged and slits are formed in the spring part to reduce the torsional rigidity thereby to prevent the inteference of the pitching and rolling movements.

摘要： A carriage assembly for a disc operating apparatus comprising a frame, a carriage movably supported in the frame relative to the disc, an optical lens or magnetic head mounted on the carriage for recording and reproducing information on the disc, and a radial guide arrangement permitting movement of the carriage in a radial direction relative to the disc. The assembly also comprises a radial drive arrangement including an electromagnetic coil mounted to the carriage and a permanent magnet mounted to the frame. The permanent magnet is electromagnetically coupled with the electromagnetic coil for driving the carriage in the radial direction of the disc. The electromagnetic coil includes two sections which sandwich the carriage and are shaped to come into contact with each other at both sides thereof, whereby the cross section of the electromagnetic coil is hexagonal in a plane parallel to a surface of the disc. As a result, the dimensions in the radial direction of the carriage assembly are decreased.

摘要： In an elevator device, a car is raised and lowered by a plurality of hoisting machines respectively including hoisting machine brakes. Each of the hoisting machine brakes has a braking force large enough to stop the car by itself. Each of a plurality of brake control sections respectively for controlling the corresponding hoisting machine brakes includes a plurality of calculation sections. The calculation sections can detect a failure of the calculation sections by comparing own results of calculations and cause a corresponding one of the hoisting machine brakes to perform a braking operation upon detection of the failure of the calculation sections.

摘要： An elevator system in which a controller monitors whether or not a speed of an ascending/descending body reaches a preset overspeed. At a time of maintenance work, a stopper is interposed between a buffer and the ascending/descending body to limit a lowered position of the ascending/descending body. A stopper detector detects installation of the stopper onto at least one of the buffer and the ascending/descending body. When the stopper is detected by the stopper detector, the controller lowers a set value of the overspeed.

摘要： An elevator apparatus includes a safety circuit section including a plurality of abnormality detection means, a safety control device, failure detection means, and circuit changeover means. The safety control device controls electric power supply to a driving device and a brake device in accordance with a content of an abnormality detected by the abnormality detection means. The failure detection means detects a failure of the safety control device. When the failure of the safety control device is detected, the circuit changeover means forms a failure-time circuit in which the electric power supply to the driving device and the brake device is interrupted directly by the abnormality detection means.

摘要： A car door is displaced with respect to a landing door between an engagement position at which the car door is engaged with the landing door and an open-away position located on a door-closing side with respect to the engagement position. While remaining engaged with the car door, the landing door is moved to open/close a landing doorway. When the landing doorway is fully closed by the landing door, a locking device performs an operation corresponding to the position of the car door with respect to the landing door to lock/unlock the landing door. A door control device has an engagement completion time calculating portion, a speed pattern generating portion, and a speed control portion. The engagement completion time calculating portion predicts an engagement completion time to a moment when the car door reaches the engagement position during a door-opening operation, based on information from an unlock detecting device for detecting whether or not the landing door has been unlocked. The speed pattern generating portion generates a speed pattern of the car door during the door-opening operation, based on information from the engagement completion time calculating portion. The speed control portion controls the speed of the car door according to the speed pattern.

摘要： In an elevator apparatus, a brake control device has a first brake control portion, a second brake control portion, and a third brake control portion. The first brake control portion operates a hoisting machine brake to stop a ascending/descending body as an emergency measure when an abnormality is detected. The second brake control portion reduces a braking force of the hoisting machine brake when a deceleration of the ascending/descending body becomes equal to or higher than a predetermined value during an emergency braking operation of the hoisting machine brake. The third brake control portion monitors a slip speed of a main rope with respect to a drive sheave during emergency braking operation of the hoisting machine brake, and reduces a braking force of the hoisting machine brake when the slip speed of the main rope becomes equal to or higher than a predetermined value.
