Patent CA-2314696-A1 (CA)
Inventor: MAKIKAWA SHINJI
IPC: G02B6/12
Filed: 2000-07-27
Abstract: A silicon substrate is prepared by furnishing a silicon substrate (10) having a step (11) of at least 5 µm high on one surface, forming by high pressure heat oxidation an oxide film (12) which is thinner than the step, and removing the oxide film on the higher surface region until the silicon surface is exposed in the higher surface region while leaving the oxide film on the lower surface region.      Because of excellent electrical properties, minimized warpage, a substantially constant oxygen concentration, and a definitely ascertainable oxide-silicon boundary, the silicon substrate is suitable for use in optical waveguide devices.

Title: System and method for monitoring vehicle conditions affecting tires
Inventor: EBERHARD CAROL A
IPC: G08C17/02
Filed: 2000-11-06
Abstract: A system and method for monitoring tread wear, shock absorber performance, balance condition of a vehicle tire, and/or rotation speed of a vehicle wheel, use a sensor to provide acceleration signals. To monitor tread wear, acceleration signals from the sensor determine at least one resonance frequency of at least one of the radial and lateral acceleration of the tire and compares it to at least one stored resonance frequency To monitor shock absorber performance, the amplitude of the Fourier component of the radial acceleration is compared to a stored amplitude value. To monitor a balance condition of a vehicle tire, the sensor provides acceleration signals measured over a specified time duration to determine an amplitude of the Fourier component of the radial acceleration that is compared to a stored amplitude specification balance condition of the tire.

Title: No hand compromise rail
Inventor: FINIGAN DOUGLAS J
IPC: E01B5/02
Filed: 2001-06-14
Abstract: A railroad track has a heavier rail section and a lighter rail section. Compromise rails join the heavier and lighter rails. Each compromise rail has a head with a heavier end to match the profile of the heavier rails and a lighter end to match the profile of the lighter rails. Each compromise rail is symmetrical about a straight center line extending from one end to the other. The width of the compromise rail tapers uniformly from the lighter end to the heavier end. This results in a slightly different gauge along the compromise rail section from the standard gauge. The different gauges are accommodated by adjusting the gauge at an end portion of the lighter rail section and at an end portion of the heavier rail section.
