Abstract: Position calculating methods and devices are described. Satellite information may be calculated, which includes satellite position, satellite movement speed, and satellite movement direction of a positioning satellite. A pseudo distance between the positioning satellite and a user may be calculated based on a satellite signal received from the positioning satellite. The position of the user may be calculated using the satellite information and the pseudo distance in executing a convergence calculation with positioning information for a reference satellite, thereby eliminating a time error term from unknown quantities.

Abstract: A piezoelectric vibration element includes: a piezoelectric substrate; excitation electrodes that are arranged so as to face each other on both principal faces of the piezoelectric substrate; drawn-out electrodes; and pads. The piezoelectric substrate includes an excitation portion that is located at the center and a peripheral portion that is thin-walled to be thinner than the thickness of the excitation portion and is disposed on a peripheral edge thereof. The pads have support areas that fix the piezoelectric substrate to a support member at positions of the piezoelectric substrate corresponding to corner portions. The excitation electrodes are formed over the excitation portion and a vibration area that is at least a part of the peripheral portion.

An interconnecting pattern positioned in one of the plurality of layers forming the interconnect layer has at least three interconnecting lines under each of the electrodes, extending parallel to each other at the same intervals.

Abstract: A liquid jetting head includes a nozzle plate, a liquid passage plate and a sealing plate. The nozzle plate is provided with a plurality of nozzle orifices. The liquid passage plate has a first face and a second face which are opposite to each other. The liquid passage plate is provided with a plurality of grooves which are arranged in a first direction perpendicular to a longitudinal direction of the groove on the first face, each groove having a communication port which passes through from the first face to the second face. The sealing plate for sealing opening faces of the grooves. The sealing plate is jointed to the first face so that a plurality of pressure generating chambers are formed. The nozzle plate is jointed to the second face such that the communication holes are communicated with the nozzle orifices respectively.

Abstract: A projection-type display apparatus includes an on-screen-display-menu generating section for generating image data corresponding to an on-screen-display menu; an image synthesizing section for synthesizing image data for projection sent from an image source and the image data corresponding to the on-screen-display menu; and an image-distortion compensation section for applying image-distortion compensation processing used to reduce the distortion of the projected image obtained when an image is projected in an inclined direction against a screen, to the image data synthesized by the image synthesizing means.

Abstract: In a projection display device which can be controlled by a remote controller, the remote controller includes a power supply switch button for turning on/off a power supply at a body of the projection display device, a zoom adjuster button for adjusting the zooming of a projection lens, and a focus adjuster button for adjusting the focusing of the projection lens. The projection display device body includes a restricting system which can restrict the adjusting functions of these buttons, so that inadvertent operation of any of these buttons does not affect the projection display device.

Abstract: A light-source lamp unit includes a light-source lamp unit detachably mounted, and a CPU constituting a drive and controller for the light-source lamp unit. The CPU senses lamp information obtained by a lamp-information storing block in the light-source lamp unit, pertaining to a lamp power rating, lamp life and whether a lamp is new or not, and starts counting operation time when the lamp is lit. The CPU compares the lamp life sensed and the operation time count, and forces the lamp to extinguish when the life of the light-source lamp expires. Prior to this action, the CPU gives a warning display before the life expiration of the lamp by a fixed duration of time, to warn that lamp replacement is needed. Because the lamp-information storing block in the light-source lamp unit stores the information about the lamp type and characteristics of the lamp, the light-source device can properly drive the lamp to light it and determine the lamp life even when a light-source lamp unit of a different type is used.

Abstract: A polarizer optical device for receiving and transmitting light is provided. The polarizer optical device includes a light separating section for separating the light into two polarization components which are othogonal with respect to one another. Further, the optical device is provided with a polarization rotating section for rotating the two polarization components so that a phase difference between the two polarization components othogonal to each other is 1/2.lambda.. Finally, a light combining section is provided for combining the light into a outputted light beam. The light combining section may be formed with a combination of birefringent prisms and isotropic mediums interfacing one another. In these configurations, the refractive index of each prism or medium is selected so that an angle formed with two unparallel incident lights differs from an angle formed with two output or transmitted lights.

Abstract: A high-speed multiplier utilizing a layout architecture requiring very little area on a chip. The present invention employs a floor plan which exemplifies regularity and is approximately 33.3% more compact than conventional Wallace Trees. During a first phase of a first clock cycle, Booth coding takes place resulting in a first group of partial products. In a second phase of the first clock cycle, the first group of partial products are input into a first and a second carry-save adder. Results from the second carry-save adder are latched in a first and second register. Also during the second phase of the first clock cycle, a second group of partial products are Booth coded. In a first phase of a cycle 2, the second group of partial products are input into the first and second carry-save adders. Results from the second carry-save adder are latched into a third and fourth register.
