  • Publication number: 20240117192
    Abstract: A method for manufacturing a surface-treated gas-phase-process silica particle, the method including steps of: adding 1,3-divinyl-1,1,3,3-tetramethyldisilazane to a raw material gas-phase-process silica particle and introducing a vinyldimethylsilyl group on a surface of the raw material gas-phase-process silica particle to obtain a preliminarily treated silica particle; and adding hexamethyldisilazane to the preliminarily treated silica particle and introducing a trimethylsilyl group on a surface of the preliminarily treated silica particle to obtain a surface-treated gas-phase-process silica particle.

  • Patent number: 5244060
    Abstract: An elevator apparatus is provided with a hoisting unit including a drive sheave for winding a rope around it. The hoisting unit includes a rotary member. The rope has a car attached at one end thereof for suspending. A braking force is applied to the rotary member by a biasing unit. The braking force against the rotary member is released by a releasing unit, and is reduced by a reducing unit. In emergency stop of such an elevator apparatus, slipping of the rope is not caused to control the braking force with ease.

  • Patent number: 5154261
    Abstract: An electromagnetic disc brake for an elevator lifting apparatus comprises a disc spline-coupled with a rotational shaft. Braking body and an armature disposed to clamp the disc; braking springs press the armature against the disc, and an iron core is provided which includes inner and outer magnetic poles each facing the armature and concentrically formed with respect to the rotational shaft. An electromagnetic coil generates magnetic flux to pass through the inner and outer magnetic poles as magnetic paths. In addition, at least one of the pole face of the outer magnetic pole and the facing portion of the armature where it faces the pole face is provided with an arrangement for increasing a magnetic gap, and the braking springs are disposed in portions of the outer magnetic pole. Further, the braking body is supported through a sound absorbing member or one side of the armature facing the disc is formed of a sound absorbing member.

  • Patent number: 5090515
    Abstract: A passenger transport installation in which a large number of people can be efficiently transported between at least two vertically-spaced places. Stations communicate with a vertical elevator passage or passages along which vehicles can move upward and downward, and the vehicles stop at the stations to allow passagers to get on and off. While passengers get on and off the vehicles at the stations, other vehicles carrying other passengers can move upward and downwardly along the elevator passage or passages.

  • Patent number: 5067593
    Abstract: A braking device for an elevator winding machine generates a braking force by contacting a rotary body driven by a rotary shaft of the winding machine with a brake section supported through the intermediary of an elastic body. The elastic body has a nonlinear elastic characteristic so that a starting shock to the passengers in the elevator car is prevented and the braking torque detecting accuracy is improved.

  • Patent number: 5025896
    Abstract: An elevator car and a counterweight is suspended on a sheave by means of a rope in a well-rope faashion. In dependence on the number of passengers on the car, the sheave is applied with an unbalance torque making appearance between the car and counterweight. Upon starting of the elevator operation by releasing a brake, upward or backward bouncing of the car takes place due to the unbalance torque. For preventing such bouncing of the car, a start compensation is performed by generating a motor torque which can cancel out the unbalance torque in precedence to the releasing of the brake. The brake is installed swingably on a winding equipment. Displacement of the brake during actuation thereof indicates the presence of the unbalance torque.

  • Patent number: 4788584
    Abstract: A semiconductor device comprising a conductive layer; an insulting layer mounted on the conductive layer and having an opening; terminals deposited on the insulating layer; an active semiconductor element mounted on the conductive layer or the insulating layer, and; a capacitor mounted on the conductive layer. In this device, a path between the semiconductor element and the capacitor is very short and the conductive layer serves as a heat sink.
