Title: Method to fabricate a mosfet
Inventor: JOHANSSON TED
IPC: H01L21/8238
Filed: 2000-08-23
Abstract: An extremely simple method to fabricate MOSFET transistors is described including enhancements of the basic concept. A key idea is that two areas of  polysilicon (1, 3) can be isolated from each other and used to isolate a thi rd silicon area (5), if the areas of polysilicon are placed from each other at a distance corresponding to the width of two side wall spacers, and then in a common way oxide or nitride spacers are formed. By means of the method described, a device with limited metallizing is manufactured using only one mask layer. Using one additional mask, the method is extended for producing simple CMOS building blocks. As an illustration the layout of the most commo n CMOS building block, a CMOS inverter, is demonstrated.

Title: Controlled stress thermal compensation for filters
Inventor: WIGLEY PETER G
IPC: G02B5/28
Filed: 2000-07-21
Abstract: A temperature compensated optical filter assembly comprising a plurality of thin films having temperature dependent indices of refraction which are deposited on a glass substrate so as to form a conventional interference filter thereon. The glass substrate is adhesively coupled to a metal holder such that the deposited thin film interference filter is interposed between the glass substrate and an adhesive layer distributed along a mounting surfa ce of the holder. Thus, a first thermal mismatch stress is applied by the glass  substrate onto an inner layer of the interference filter and a second mismat ch stress is applied by the holder onto an outer layer of the interference filter, wherein the first and second mismatch stresses depend on the temperature of the filter assembly. The glass substrate, the adhesive, and t he holder are preferably formed of materials having mechanical properties such that the first and second mismatch stresses compensate for the effects of th e temperature dependent indices of refraction of the thin films so as to uniformly maintain the spectral performance of the filter assembly in respon se to a change in temperature. In one embodiment, an additional degree of freed om is obtained by electro/magneto-strictively prestressing the thin film stack during the formation thereof. In another embodiment, an active stress management system is utilized.
Patent CA-2387775-A1 (CA)
Inventor: BROWN GARY
IPC: H01H13/18
Filed: 2002-05-28
Abstract: A flow switch for a high pressure washing system or other flow-related system is disclosed. The flow switch switches from an open to a closed position in the presence of adequate flow in a water or other fluid-carrying pipe.      The flow switch includes a housing with an inlet port and an outlet port which allows fluid to flow through the housing. Within the housing is a plunger with an attached magnet. The plunger is responsive to fluid flow. A retainer ensures that the plunger remains within the housing. A sensor is situated proximate to the housing. A sensor magnet is placed in position near the sensor and opposes the plunger magnet. When there is no flow within the housing, the plunger is at its rest position as it is repelled by the sensor magnet. When a threshold rate of flow is present, the pressure from the flow overcomes the repellant force of the magnets and the plunger is moved to its secondary position. In this position, the plunger magnet trips the sensor.
