Abstract: The present invention relates to a color type liquid crystal display having a high aperture ratio, comprising a first substrate which has black matrixes of a color filter arranged in a stripe and a second substrate which has black matrixes in a stripe perpendicular to the black matrixes of the color filter. The disclosed has a large alignment margin without deterioration when an upper and a lower substrates of color type STN are assembled each other, thereby increasing an aperture ratio and yield and decreasing power consumption.

Abstract: The invention relates to polyolefin copolymers (I) 1

Abstract: The present invention relates to a method of assigning an e-mail address with a user chosen ID. More particularly, the present invention relates to a method of assigning an e-mail address with a user chosen ID by employing a website which does not currently provide a web mail service. According to the present invention, a user doesn't have to visit many websites to get an e-mail address with his or her chosen ID. Furthermore, the website which provides a web mail service by assigning an e-mail address according to this invention can gain an advantage over other websites providing a web mail service, and therefore, can raise more members.

Abstract: There is disclosed an option function test apparatus of a semiconductor device including a function selecting means. The function selection means includes a fuse signal detecting section for sensing the state of fuse blowing, a pad signal detecting section for sensing the signal state on the probe pad for selecting its specification, which is consisted by incorporating extra probe chips into the existing probe card, and a global signal control section for receiving the output signals from said fuse signal detecting section and said pad signal detecting section to output different output signals based on its operation mode. Thus, the present invention can provide an outstanding effect of reducing additional test time and cost depending on the changes in function, since it allows a multifunction test of all of the specifications mounted on the on-chip in a wafer state.

Abstract: An improved optical pick-up apparatus capable of reading data irrespective of disc type capable of reading various kinds of discs having different thicknesses and writing densities using only one pick-up apparatus, which includes a light source; a beam splitter for passing through or splitting a beam from the light source; an objective lens for condensing the beam onto corresponding disc among discs having different thicknesses and different densities; a numerical aperture control unit for controlling an effective numerical aperture of the objective lens so as to execute a focussing operation with respect to a certain disc; and a photo-detector for receiving the beam reflected by the disc and transmitted from the beam splitter.

Abstract: An optical pickup apparatus including an improved objective lens having at least one ring-shaped mask for preventing aberrations caused by differences in the thickness of discs being reproduced. The objective lens is capable of achieving improved focus by removing aberrations which occur when reading data from discs having different recording densities and thicknesses. The masks formed in the objective lens has a predetermined mask radius (r.sub.n +1) and a predetermined mask width (.DELTA.r.sub.n +1).

Abstract: An improved optical pickup apparatus for different discs which is capable of writing and reading a data onto discs having different writing densities and thicknesses by using one optical pickup apparatus and a liquid crystal deflector (LCD) or a Grating Polarizing Beam Splitter (GPBS). The apparatus includes an objective lens for focusing a beam onto optical discs each having different thicknesses, and a numerical aperture control means for selectively passing through a beam in accordance with the thickness of the optical discs, diffracting a portion of the beam, and controlling the numerical aperture of the objective lens.

Abstract: A robot comprises a member traveling along a threaded rotary shaft which decelerates when the member approaches a predetermined location on the shaft. Rotation of the rotary shaft is subjected to a resistance imposed by a fluid whose viscosity is increasable by the application of an electrical charge to the fluid. The point at which the rotary shaft begins to decelerate is sensed, and an electrical charge is applied to the fluid to increase its viscosity and attenuate vibration of the member.

Abstract: The present invention is directed to a method of improving the potency of a vaccine in a mammalian host comprising administering a therapeutically effective amount of a vaccine and a potency improving amount of IL-7. In a preferred embodiment, the IL-7 is dissolved or dispersed in a pharmaceutically acceptable carrier. The pharmaceutically acceptable carrier is preferably in the form of a lipid dispersion.

Abstract: A noise attenuator for a refrigerant-circulating compressor includes a casing whose interior space is divided into first and second chambers. The first chamber has an inlet for receiving refrigerant and is connected by a conduit with the second chamber. Additional conduits connect the second chamber with the compressor inlet. The cavity length L of the first chamber is determined as a function of a compressor noise to be attenuated, using the formula fr=C/4L (2n+1), where fr is the frequency of the noise, C is the speed of sound in refrigerant, and n is any whole integer (including zero). The first chamber may comprise a first portion and a second portion in the form of a branch line, with the cavity length L being defined by a combination of both of the portions.

Abstract: A refrigerator comprises a lot of hollowed projections provided on the bottom of a reservoir and an auxiliary condenser secured to the top of the hollowed projections by supporting pieces in which one end is fixed in contact with the outer surface of the auxiliary condenser and the other end is fixed along one face of the hollowed projections so as to always be in contact with water, thereby improving the cooling efficiency of the auxiliary condenser and the evaporation efficiency of the water by directly transferring heat radiated from the auxiliary condenser to the water through supporting pieces.
