Abstract: The present invention relates to a height-adjustable chair, mainly comprising a first post, a second post, a lock clamp, a seat and a seatback. The first post is of a section of sleeve tube with a tripod mount for the chair to stand on the ground. The second post is also a section of sleeve tube permissible to rise and lower in the first post with a pivot brace and a plurality of support rods for holding the seat and the seatback of the chair. The second post is permitted to slide in and out freely in the first post. A quick-action lock clamp is fixed between the first post and second post, convenient for the operator to easily press the lock wrench for rising or lower the second post within the first post and adjust the height of the chair as it suits his gesture.

Abstract: A flat plate mold with special treatment or a metallic flat plate mold is adopted to flatten the resin painted over on IC chips during package dispensing process, such that it is able to maintain a consistent flatness of the surface of IC products after dispensing for laser or ink marking. And heat sinks can be attached to the flat plate mold to increase the heat-dissipating rate of IC products after dispensing.

Abstract: A fire-proof refuge shelter includes a plurality of partition walls joined together by bolts and screws to form a closed box provided with a pair of sliding doors, characterized in that: each of the partition walls being made of a surface layer, an intermediate heat-resistant layer and an inner heat-resistant cement layer, the surface layer being made of fire-proof glass fiber or calcium silicate or mineral fiber, the inner heat resistant layer being a fire-proof sound absorbing board made of lightweight bone concrete or made by solidation of heat resistant concrete, and the intermediate heat resistant sand layer being made of non-combustible clay, silicon stone or substance primarily consisting of carbon, whereby oxygen tanks, flashlights and so on are arranged inside the shelter for people who waits for rescue.

Abstract: Compounds of formula (I) are disclosed which are vitronectin receptor antagonists useful in the treatment of osteoporosis.

Abstract: This invention relates to substituted bis-acridines and related compounds which are ligands, in particular, antagonists of the CCR5 receptor. In addition, this invention relates to the treatment and prevention of disease states mediated by CCR5, including, but not limited to, asthma and atopic disorders (for example, atopic dermatitis and allergies), rheumatoid arthritis, atherosclerosis, psoriasis, autoimmune disease such as multiple sclerosis, and inflammatory bowel disease, all in mammals, by the use of substituted bis-acridines and related compounds which are CCR5 receptor antagonists. Also, since CCR5 is a co-receptor for the entry of HIV into cells, selective receptor ligands may be useful in the treatment of HIV infection.

Abstract: This invention relates to certain tricyclic compounds that are integrin receptor antagonists.

Abstract: A pulse shaper for integrated service digital network (ISDN) U-interface. The pulse shaper of the present invention includes a couple of control clock generators, a clock-controlled fully differential switched-capacitor integrator, a fully differential sample and hold circuit, and a fully differential line driver/Rauch lowpass filter. The pulse shaper converts four-level 2B1Q digital input code (D0 and D1) to five staircase-type analog waveform by using fully differential switched-capacitor integrator. The sample and hold circuit then eliminates the spikes in the five-stair waveform and improve the signal linearity. The lowpass filter and telephone line driver is utilized to perform the output signal to comply with the waveform specification of ANSI T1 5.3.2.1 and 5.3.2.2.

Abstract: A container includes a housing attached to a block for receiving the aromatic material and having a number of orifices for allowing the perfume of the aromatic material to be blown out of the housing. A frame includes a track for slidably supporting the block. One or more wheels are rotatably secured to the frame and coupled to the block by cranks and links and legs. A light bulb is attached to the block, and a switch may be used to control the operation of the light bulb. The block may be attached to a support device by a clipper or the other fasteners.
