Abstract: To achieve a projection lens which has a wide angle view, a short projection distance and telecentricity and in which the projection can be performed with high contrast, various aberrations such as distortion aberration, etc. are reduced and the optical path is converted.     A first lens group having negative refractive power and second and third lens groups having positive refractive power are arranged from a longer conjugate side. Representing a back focus at a projection distance of infinite point by BF; the composite focus distance of the entire system by F; the central air spacing between said first lens group and said second lens group by GD1; the composite focus distance of said first lens group by Fl; the composite focus distance of said second lens group and said third lens group by F23; and the central air spacing between said second lens group and said third lens group by GD2, the following equation is satisfied: [2.8 < BF/F] [3.0 < GD1/F < 4.50][0.40 < -F1/F23 <0.48][0.40 < GD2/F23 <0.8].  At this time, the focus adjustment is carried out by moving the first lens group along the optical axis OA.

Title: Cocktail watermarking on images
Inventor: LU CHUN-SHIEN
IPC: G06T1/00
Filed: 1999-10-05
Granted: 2005-03-29
Abstract: A novel image protection scheme named "cocktail watermarking" improves over current spread-spectrum watermarking approaches. Two watermarks, which play complementary roles, are simultaneously embedded into an original image. The new watermarking scheme has the characteristic that, no matter what an attack is, at least one watermark typically survives well and can be detected.      Results of extensive experiments indicate that our cocktail watermarking scheme is effective in resisting various attacks.

Abstract: A grinding swarf collector is disclosed. An outer periphery and side surfaces of a grinding wheel, except a site of grinding including a grinding point, are covered with a cover. A dust collecting plate is disposed behind the grinding point in a direction of rotation of the grinding wheel. Swarf scattered rearward collides with the dust collecting plate, and is scooped up thereby toward a suction port. The suction port sucks the swarf, which is sucked into a vacuum cleaner. Swarf scattered around the grinding wheel collides with the cover, falls to an opening formed below, and is sucked through the suction port.      Thus, grinding swarf is collected efficiently.

Title: Forwardly folding agricultural planter
Inventor: HUNDEBY DAVID R
IPC: A01B73/06
Filed: 1999-11-10
Granted: 2009-01-20
Abstract: An agricultural planter is provided with hydraulically operated devices to effect the folding and unfolding of the planter support structure between operative and transport configurations. The planter includes a telescopic hitch apparatus that lengthens as the pivoted wing members are folded forwardly to position a transport lock mechanism for engagement with vertically oriented wing latch retainer bars mounted in a latch tower on the draw bar. A hitch latch mechanism is also provided to control the movement of the telescopic draw bar. A caster lock apparatus is also provided to control the castering action of a wheel device positioned near the ends of the wing members. In operation, the laterally extending tool bar is pivoted on a transverse axis to forwardly roll the tool bar toward an intermediate transport position. Once the tool bar is properly positioned, wing fold hydraulic cylinders pivot the laterally extending wing assemblies forwardly to effect engagement between the transport lock mechanism and the latch tower. An unfold abutment finger is provided to allow the wing assemblies to float with changing ground undulations, while providing a abutment against which the wing cylinders can push to effect unfolding of the wing members. A tool bar lock fixes the tool bar in a forwardly rolled transport position.

Abstract: A method for heat treating a mold cast product comprises releasing the product from a mold and hardening the product.  Since the mold release is performed when a surface layer of the product held in contact with the mold has a hardening allowing temperature and after it becomes a shell-shaped solidified layer, the product immediately after released from the mold has a heat suitable for hardening. Using this heat, the product is thereafter hardened by means of a cooling agent. As a result, a heating process required for hardening can be omitted, thereby achieving energy conservation.

Abstract: An electronic faucet having a spout, a electronically actuated valve, and a microprocessor-based control circuit for operating the valve to enable or disable water flow through the spout. The microprocessor has a control program which includes a calibration routine that uses an infra-red sensor to determine an adjustable setpoint indicative of the signal received from the sensor in the absence of an object in front of the faucet. The microprocessor switches the valve from its closed state to its open state when the signal from the sensor either increases above the setpoint by a selected amount or decreases below the setpoint by a selected amount. This provides a window about the setpoint within which differences between the setpoint and the signal do not result in opening of the valve. Object detection is accomplished using a tracking routine that adjusts the setpoint in an attempt to track the sensor signal. If the sensor signal undergoes a change that is too large to be tracked, then the microprocessor switches on the valve. Once the sensor signal drops back into a range of values about a stored calibration point, the valve is closed. The control circuit is part of an electronics module that is mounted within the spout and that is held in place between the spout tube and the spout housing. The module includes a curved recess having a shape that conforms to the spout tube so that the module is retained in place at its upper end by the spout tube.
