Title: Liquid crystal display mounting structure
Inventor: ICHIKAWA SHINPEI
IPC: G02F1/1333
Filed: 1990-05-31
Abstract: A mounting for liquid crystal displays in a portable computer and a method for making the mounting structure are described. The mounting absorbs the shocks associated with day-to-day handling of the portable computer including occasional dropping or compressing, and thereby protects the LCD (40) from damage. The mounting consists of resilient shock absorbers (42a, 42b) mounted along the edges or at the corners of the LCD and glass assembly which are preferably sealed with the LCD glass and circuitry in a three-dimensional frame. The sealed mounting acts as a suspension system which allows the LCD glass to float and remain planar within a deformed housing (41). Any shocks due to dropping, compressing, bending or deflecting are absorbed by the shock absorbers and the LCD  remains unaffected. The mounting may be evacuated and hermetically sealed, which provides protection to the LCD glass and circuitry from humidity, dust, etc.

Title: Carpet stretcher attachment utilizing pivotally mounted pulling plate
Inventor: HYER RAYMOND E
IPC: A47G27/04
Filed: 1992-08-21
Abstract: Abstract of the Disclosure A portable carpet stretching device in accordance with this invention enables a user to stretch carpeting at an angle into engagement with a tack strip affixed along the base of an adjacent wall, thus to eliminate wrinkles. Our novel device comprises a carpet-engaging head member and a relatively fixed base member. The front of the base member is attached by an extensible member to the rear of the head member, and anchoring means are utilized for securing the base member with its front portion in a fixed relationship to the adjacent wall. Power applying means are provided for enabling the user to force the head member and the base member apart, so the anchoring of the base member with respect to the adjacent wall by the anchoring means results at the time of application of the power means, in the portion of the carpet engaged by the head member bring forced toward the adjacent wall and into contact with the tack strip. The anchoring means forming the principal subject matter of this invention comprises a pulling plate having a lower edge adapted to engage the tack strip. The upper edge of the pulling plate is pivotally connected to the base member, with this pivotal connection enabling said the head member to be moved into a non-symmetrical relationship to the pulling plate, whereby a pull at an angle to the adjacent wall can be applied to the carpet when the power applying means is operated.
