Abstract: The object of this invention is to provide a cap for liquid containers. The cap consists of a mounting part (1) mounted to the mouth of a container, a liquid discharging part (2) extending from the top of the mounting part (1) upwardly. In this liquid discharging part (2), a liquid outlet opening (2a) and an air inlet opening (2b) are formed at opposite positions of the sidewall, while a partition wall (23) extends from the top wall (22) downward, thus partitioning the interior of the part (2) into a liquid passage (2a') and an air passage (2b'). An openable top cover (4), connected to a side of the mounting part (1), covers the liquid discharging part (2). When liquid is discharged from the container through the liquid outlet opening (2a), atmospheric air is smoothly introduced into the container through the air inlet opening (2b) without causing uneven flow or violent gush of the outlet liquid.

Title: Bump layout on a chip
Inventor: YANG WEN-JR
IPC: H01L23/50
Filed: 2001-08-06
Granted: 2002-10-11
Abstract: A bump layout on a chip is employed to arrange bumps on the active area of entire chip so as to increase the number of bumps. For the chip with a long and narrow structure, the bumps are arranged on the active area close to long sides of the chip and on the part of central portion of the active area. When the chip-on-glass process is conducting, the disadvantage of lighter indentation occurred on the active area close to short sides of the chip can be avoided due to no arrangement of any bump in the place. Otherwise, dummy bumps can be arranged on the active area close to the short sides of the chip to optimize the uniformity of the main bonding strength in the chip-on-glass process.

Filed: 2001-09-26
Granted: 2004-01-21
Abstract: An apparatus and method for reproducibly interfacing a living tissue sample to the measurement probe of a spectrometer instrument in-situ minimizes spectral interference related to sampling variations. A minimal contact subject interface includes supports replaceably mounted on a base. An optical coupling means, such as a fiber optic probe, contacts the measurement site through a probe aperture in the base. During use, a subject rests an extremity on the support elements, so that the extremity is reproducibly positioned and supported in relation to the optical coupling means. The supports have a small contact area, minimizing contact with the skin at the measurement site. The interface module is adjustable to fit any subject. By reproducibly positioning and supporting the body appendage using minimal contact supports, spectral interference due to variations in placement, applied pressure, and temperature transients secondary to contact with the interface module are greatly minimized.
