Title: Liquid crystal display and its manufacturing method
Inventor: YANO TOMOYA
IPC: G02B5/02
Filed: 1995-08-11
Abstract: With the liquid crystal display provided by the present invention, the display contrast is improved by suppressing the reflection of an external light by a light diffusing layer employed in the liquid crystal display.     The liquid crystal display comprises a liquid crystal panel 1, a directional backlight 2 and a light diffusing means.  The liquid crystal panel 1 is of the transmission type having a front face and a back face on the side opposite to the front face.  A polarizing plate 4 is placed in front of the front face of the liquid crystal panel 1.  The backlight 2 is placed on the back side of the liquid crystal panel 1, providing all but parallel incident illumination light beams to the liquid crystal panel 1.  The light diffusing means is placed on the front side of the liquid crystal panel 1, diffusing and emitting the incident illumination light beams leaving the liquid crystal panel 1.  The light diffusing means comprises a light diffusing layer 9 and transparent filler stuff 10.  The light diffusing layer 9 is made up of transparent fine particles 9a spread all over the gap between the front face of the liquid crystal panel 1 and the polarizing plate 4.  The transparent filler stuff 10 is used for filling up gaps among the transparent fine particles 9a.  The transparent fine particles 9a each have a refraction index different from that of a glass plate 3 constituting the front face of the liquid crystal panel 1 while the transparent filler stuff 10 has a refraction index close to that of the glass plate 3.

Patent CA-2156876-A1 (CA)
Inventor: ALLEN JONATHAN BRANDON
IPC: H04Q3/72
Filed: 1995-08-24
Abstract: Methods and apparatus are disclosed for improving the clarity and intelligibility of incoming speech in a telephone connection. Improved sound quality is provided by automatically selecting, or enabling the selection of, an appropriate sound enhancement for a particular individual at a given telephone number. Sound enhancements applied to calls originating from or terminating at a given telephone station are determined on a call-by-call basis. The sound enhancement set at the beginning of a telephone call can be changed mid-call to a different sound enhancement. Thus, different occupants of a household may select their own sound enhancement, or may select no enhancement at all.
Patent CA-2157001-A1 (CA)
Title: Fire starter and method of making same
Inventor: REIGER CRAIG M
IPC: C10L11/06
Filed: 1994-02-23
Abstract: A fire starter (20) consists of a ring-shaped mass of combustible material having integrally formed spacers (28) for supporting the mass of material above a supporting surface (26), such as the floor of a fireplace. The ring shaped mass of material consists of a series of inverted frusto-conical sections (28) connected together by a series of inverted triangular connecting sections (30), all of which are formed of a solidified wax and wood mixture.     During manufacture, the wax and wood mixture is subject to relatively high pressure on the over of 700 psi to 800 psi, to compress the mixture and to yield a relatively high density to the fire starter material. Such pressurization of the material insults in formation of a veneer layer (60) on the outer surfaces of the file starter, with the veneer layer consisting primarily of wax. The fire starter includes a substantially central aperture (54). During combustion of the fire starter, a venturi effect is created by a flow of air to the aperture, to provide a relatively high, intense flame. The fire starter burns for a substantial period of time, such as 8-12 minutes, and the duration and intensity of the flame generated thereby is capable of igniting conventional fireplace logs without the use of kindling. The invention further involves a packaging arrangement in which multiple fire starters (20) are placid in vertical stacked relationship within the internal cavity of a tubular package (86). A rolled sheet (92) of instructions is inserted through me aligned apertures in the stacked fire starters.

Title: Brake Control Device for Railroad Rolling Stock
Inventor: DOTO SHIGEAKI
IPC: B60T8/17
Filed: 1996-03-01
Abstract: Brake control device for railroad stock has a braking force setting unit to add a braking force command signal for a powered car and braking force command signals for trailer cars and output a composite command signal. A main control device receives such composite signal and generates an electrical braking force. A braking force computation unit splits an error in an electrical braking force equivalent command signal corresponding to an actual electrical braking force with respect to such composite command signal into a supplementary hydraulic braking force command signal for a powered car and supplementary hydraulic braking force command signals for trailer cars and outputs results to hydraulic brake devices of such cars, wherein the command signals of such trailer cars are individual car command signals obtained by splitting such command signals in rolling stock units a plurality of times. Such setting unit adds such command signal for such powered car and such plurality of individual trailer car command signals and the braking force computation unit computes and outputs a trailer car braking force load element in such electrical braking force equivalent signal as a plurality of individual trailer car braking force load signals in response to such individual car command signals and computes and outputs such supplementary hydraulic braking force command signals to such hydraulic brake devices of such cars based on the command signals in such rolling stock units for such cars and a sum of individual trailer car braking force load signals associated with such cars.

Title: Method of producing and detecting high-contrast images of the surface topography of objects and a compact system for carrying out the same
Inventor: METZ MICHAEL H
IPC: A61B5/117
Filed: 1995-02-21
Abstract: A method and ultra-compact system has been developed for illuminating and detecting the surface topography of an object such as the finger (4) of an individual. The system (8) is capable of producing highcontrast images which can be electronically transmitted in real-time, or stored using electronic or photographic recording devices. Light traveling within a light transmitting substrate (2) is redirected by a slanted-fringed light diffractive grating preferably embodied within a volume hologram (3). The volume hologram (3), either of the reflection or transmission type, is attached to the light transmitting substrate (2), and functions to diffract light striking thereupon and illuminate an object having topographical surface structure. After being spatially and intensity modulated in accordance with topographical details of the illuminated object, the insulated light passes back through the light transmitting substrate (2) and the volume hologram (3), onto an image detection array, for subsequent analysis. Each of the disclosed embodiments has a compact geometry suitable for use in diverse object identification applications.
