Title: Method for connecting bridge of glasses
Inventor: KIM KYUNG NAM
IPC: G02C5/02
Filed: 1998-12-23
Abstract: PURPOSE: A method for connecting the bridge of glasses is provided to improve convenience of a user while improving the quality of the glasses by preventing the bridge from being removed or being broken by supplying a new connecting method. CONSTITUTION: Glasses(10) are formed by light metals such as nickel, titanium, cobalt, or the Monel Metal. The glasses are composed of glass frames(12) to combine lenses(11), legs(14) projected from the both sides of the glasses frame to rear direction while having hinges(13), and a bridge(15) connecting the glasses frames. Herein, the bridge is formed by a shape memory alloy for adding the compensating function of shape to the glasses transformed by temperature or external force. However, the compensating function of shape is lost caused by welding temperature while welding the bridge to the glass frames. Therefore, a new method for connecting the bridge to the glass frames prevents the loss of the compensating function of shape in the bridge.

Herein, sealing plates having exhaust blows are fixed to upper/lower portions of the block plates to form an exhaust suction chamber between the discharge apertures. A microwave transfer waveguide having a magnetron and a block plate are attached to front directions of the waveguides. A compressed carbon rod is installed in the waveguide(2) having the block plate.

Abstract: PURPOSE: A reusable collimator of multi-layer structure is provided to be capable of effectively removing a metal source attached to collimator during the sputtering process without damaging the original material. CONSTITUTION: A reusable collimator of multi-layer structure is installed between a wafer and a target(20) and is used in the sputtering process. A coating layer(20b) made of a material such as Pt or Pd having the property chemically and physically similar to a collimator material(20a) is formed on the surface of the collimator material.

Title: Laser irradiation process
Inventor: OKUMURA HIROSHI
IPC: H01L21/268
Filed: 1999-08-03
Abstract: PURPOSE: The method is provided to form a polysilicon film having uniform grain size distribution and good grain arrangement. CONSTITUTION: A pulse laser beam having a rectangular irradiation region is irradiated on the same position of a semiconductor film many times. The pulse laser beam has a energy profile of longitudinal direction of beam irradiation region as follows; (a) it has a first region having Ea or more energy density and a second region having Ea or less energy density and located on either side of the first region (b) the energy density gradient has the absolute value of 20 to 30 J/cm¬3 in the boundary region extended by 1 micrometer from boundary of the first region and the second region.
