Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To provide an X-ray alignment method, X-ray aligner and X-ray mask that is capable of preventing X-ray mask damages or transfer pattern defects. SOLUTION: A laser beam 4 is transmitted from a laser light source 2, in parallel with a wafer 7 suction-attached on to a wafer stage 8 and an X-ray mask 6 placed with a certain gap above the upper surface of the wafer 7. A transmitted light 5 that transmits between the wafer 7 and the X-ray mask 6 is received at the laser receiving unit 3. The quantity of light is measured, and foreign matters are detected by checking the decrease in the quantity of light. After the distance between the laser beam 4 and the wafer 7 is adjusted to a certain distance by a location detector 10, the wafer stage 8 is moved horizontally in a direction normal to the paper while keeping a certain distance and the quantity of light is measured at the laser receiving unit 3 to detect foreign matters 9 over the entire wafer 7. If any foreign matter 9 is detected on a wafer 7, the foreign matter 9 is removed and the wafer is further cleaned. Alternatively, the wafer is not exposed. Similar process is applied to the X-ray mask.

Improved cooling is provided by utilizing an end plate with apertures and a brush plate which in combination with the commutator, provides a brush plate aperture for cooling air flow. In a preferred embodiment, speed variations of the motor can be achieved by selectively disconnecting one or more brushes in a four brush embodiment reducing the torque and rotating speed of the motor. In a preferred embodiment, the use of a diode to interconnect same polarity brushes permits a speed change to be accomplished by selectively connecting one or the other end of the diode. In a further preferred embodiment, the stalling of the motor having power applied is indicated by an electronic output where voltage applied to one brush is filtered through an RC filter with the output amplified and voltage doubled. A ripple output indicating that the motor is rotating after amplification will light a light emitting diode indicating proper operation of the motor.

Title: Lod with increased pixel opening sizes.
Inventor: BOER WILLEN DEN
Filed: 1996-06-06
Abstract: A liquid crystal display having an increased pixel aperture ratio is disclosed along with a method of making same. An array of a-Si TFTs is deposited on a transparent substrate. Subsequently, an organic insulating layer (e.g. Benzocyclobutene) and a corresponding array of pixel electrodes are deposited over the TFT array so that the pixel electrodes overlap the display address lines thereby increasing the display's pixel aperture ratio. The low dielectric constant e (e.g. about 2.7) and relatively high thickness (e.g. greater than about 1.5(m)of the insulating layer reduce the pixel electrode-address line parasitic capacitance Cpl) in the overlap areas thereby reducing cross-talk (or capacitive coupling) in the display. In sum, an increased pixel aperture ratio is achieved without sacrificing display performance.

Patent MX-9702800-A (MX)
Title: A thermo-volumetric motor.
Inventor: MURPHY PETER LAWRENCE
IPC: F03G6/00
Filed: 1995-10-20
Abstract: A thermo-volumetric motor (10) comprising a continuous fluid path in the form of a refrigerant path (12), and a solar collector (14). The continuous refrigerant path (12) includes a first heat exchanger (16), flow converting means (18), a pump (19), and a condenser (20). The flow converting means (18) may comprise a turbine or a resilient tube and a rotor. The first heat exchanger (16) comprises a shell and tube arrangement, the shell containing a first phase change substance having a relatively high latent heat of fusion. In use, heat from sunlight absorbed on the solar collector (14) fuses a portion of the first phase change substance. The refrigerant in the heat exchanger (16) cools the first phase change substance causing it to solidify and the refrigerant then absorbs the latent heat of the first phase change substance. The refrigerant thereby expands and flows from the heat exchanger (16) to the flow converting means (18) via the throttle valve (21) thus providing motive power.

Title: Corrosion preventing buffer system for metal products.
Inventor: HEIMANN ROBERT L
IPC: C23F11/00
Filed: 1995-10-19
Abstract: A system is disclosed for inhibiting the corrosion of ferrous and other metals by passivating the metals. The system includes novel buffered compositions which may be applied to metal products for preventing or retarding corrosion and methods for applying the buffered compositions to metal products such that corrosion protection of the products is achieved through passivation. The methods include an in-situ application to existing structures with metal reinforcement as well as applications to metal products during manufacture. Generally, the compositions may be in various forms and comprise a carrier component and one or more pH buffer components. The buffer is selected to retain the proximity of the metal at a pH at which the metal is passive to corrosion. The compositions are environmentally friendly and are capable of replacing chromates which have been traditionally used with zinc and zinc alloys to inhibit corrosion of metals but which are potentially harmful to the environment.

Title: Echo cancellation using cross-correlation of buffered receive and transmit sample segments to determine cancelling filter coefficients.
Inventor: TRAILL DOUGLAS MACKAY
IPC: H04B3/23
Filed: 1997-04-23
Abstract: An echo detection system comprises data stores (8, 18) for storing signals from up and down channels (5, 15) respectively. The signals undergo pre-processing (9, 19) to identify signals forms characteristic of speech and instruct the measurement unit (10) to carry out comparison using cross-correlation techniques between the signals stored in stores (8, 18) only when such characteristics are detected. This reduces the processing power required and raises the accuracy of the correlations. Parallel processing techniques allow echoes with longer delay periods to be detected. The results of the measurement may be used to generate an echo-cancellation signal (units 7, 17).
