  • Patent number: 6885532
    Abstract: A current detection circuit applicable to a switching circuit using switching transistors to supply a prescribed load current to a load, comprises a sample-hold capacitor for temporarily holding a terminal voltage of the switching transistor that is turned on, and a switch that is inserted between the switching transistor and sample-hold capacitor and is controlled to be turned on in synchronization with the ON-timing of the switching transistor, wherein charged voltage of the sample-hold capacitor is detected as a detection voltage. An overcurrent detection circuit is constituted in such a way that the switching transistor is compulsorily turned off when the detection voltage exceeds reference voltage. The switching circuit may correspond to a pulse-width modulation (PWM) amplifier using a pair of a PMOS transistor and an NMOS transistor that are alternately turned on or off.

  • Patent number: 6885755
    Abstract: Main image information representing a portrait face image of a person is prepared. Predetermined pattern image information, used as sub image information, is also prepared. Synthetic image information is prepared by synthesizing the main image information with the pattern image information in such a manner that the pattern image information is embedded in the main image information in a state that is not recognizable to the eye of a human being. This synthetic image information is recorded on an ID card or the like as a visible image.

  • Patent number: 6885984
    Abstract: An apparatus for aiding a machinist in preparing a machining program. A machining simulator simulates a basic machining program. Values of machining variables are obtained during the simulation and stored in a simulation result data memory. A spindle load determiner, a cutting speed determiner, and a rotating speed determiner analyze the machining variable values of a certain machining process to determine the machining efficiency of that process. A navigation information memory stores a plurality of messages for giving advice on how to change the cutting conditions. A message, which depends on the analysis of the machining variable values, is selected from the memory and is shown on a display. Accordingly, an operator can easily modify the basic machining program by following the message on the display, even if the operator does not have much knowledge or experience.

  • Patent number: 6885558
    Abstract: An electronic apparatus has a housing having one end, components contained in the housing, and a door which is lockable at a closed position to hide one end of the housing. The housing has a base to support the door, and a cover connected removable to the base.

  • Patent number: 6881455
    Abstract: A liquid crystal display element includes array and counter substrates provided opposite to each other. The array substrate is covered with a color filter layer. Pixel electrodes are provided in a matrix form on the color filter layer. The surface of the counter substrate is provided with a common electrode. Alignment films are coated on the pixel and common electrodes. A gap defined between the array and counter substrates are filled with a liquid crystal material to form a liquid crystal layer. The alignment films are processed to have surface energy within the range from 51 to 60 dyn/cm. Such surface energy substantially prevents an image-sticking phenomenon of the liquid crystal display element caused by impurities dissolved into a liquid crystal layer and white or black turbid spots caused by hydrolysis of the alignment films by moisture in the liquid crystal layer.

  • Patent number: 6880405
    Abstract: A differential pressure indicator has a housing with at least two ports in the housing. One port receives a first pressure, and the second port receives a second pressure. A pressure resistive device is placed between the first port and the second port. The pressure resistive device changes its position when the first pressure exceeds the second pressure by a predetermined amount. A magnet is coupled to the pressure resistive device. A digital displacement sensor senses the position of the magnet. The digital displacement sensor is in communication with an electronic indicator. The electronic indicator activates when the first pressure exceeds the second pressure by a predetermined amount.

  • Patent number: 6882366
    Abstract: An electronic imaging system includes a CCD image sensor arrangement having a two dimensional array of pixels. The pixel array converts light incident thereon to an electric signal. The pixels are arranged in a plurality of horizontal rows or lines, the lines being arranged vertically. A control arrangement selectively controls operational modes of the system. One mode provides for sequential scan reading out of pixel signals for entire lines of the CCD for still picture recording. Another mode provides for reading out pixel signals concerning k (k is a positive integer) vertically continuous lines of the CCD for still picture recording or dynamic image processing. Thus it is possible to provide a high pixel density solid-state image sensor output at a high frame rate without use of any high drive frequency.

  • Patent number: 6881700
    Abstract: A catalyst support comprising silicates is described. This catalyst support has a lower aluminum content than naturally occurring sheet silicates and can be used in the hydration of C2 and C3 olefins to produce C2 and C3 alcohols. A method for the production of the catalyst support and a process for hydrating C2 and C3 olefins are also described. One advantage of this catalyst support is the reduction in aluminum leaching that occurs when this catalyst is used in the presence of phosphoric acid.
