Abstract: The present invention discloses a light emitting diode (LED) by using a P-type ZnTe layer or a ZnSe layer as a substrate. To match the lattice between the substrate and blue light LED of cubic crystal, a BP(boron phosphide) buffer layer of single crystal is formed on the substrate. When the blue light LED emits blue light of wavelength from 450 nm to 470 nm, the ZnTe or ZnSe substrate absorbs the blue light and emits yellow-green light of wavelength 550 nm. Thus, white light is produced by mixing the blue light and the yellow-green light.

Abstract: An interrupt signal processing apparatus, when receiving an interrupt requesting signal from one device, writes a pulse signal generated by an interrupt setting pulse generating section to a register. The interrupt signal processing apparatus, when receiving an interrupt clearing request signal from the other device, clears the register by using a pulse signal fed from the interrupt clearing pulse generating section and outputs the interrupt permission signal to the one device. When a clock speed of the other device is lower than that of the one device and when pulse generation is controlled by a control signal fed from the clearing pulse generating section of the other device, while the pulse signal fed from the other device is input to the delay circuit, a time delay is provided to operations of the second synchronization section. Thus, smooth interruption can be implemented regardless of the clock speed.

Abstract: A method for manufacturing a semiconductor device which enables favorable back-surface grinding of a semiconductor substrate with preventing a warp in the substrate, thereby manufacturing a thickness-reduced semiconductor device. A projection electrode is formed on a surface of a wafer. A resin layer is formed on the wafer surface to a thickness to bury a top of the projection electrode. A cut groove is formed in the resin layer along a scribe line formed on the wafer. Thereafter, grinding is made on a back surface of the wafer by the use of a grinder or the like. A surface portion of the resin layer is removed by etching or the like, to expose the top of the projection electrode. The wafer is cut along the cut groove to obtain individual semiconductor chip pieces.

Abstract: Method and apparatus for automatically dynamically adjusting prestressed bearings of shaft are provided. The apparatus comprises a sleeve assembly having outer and inner sleeves sandwiched between the bearings. An inner diameter of outer sleeve is smaller than an outer diameter of inner sleeve. Hence, outer and inner sleeves are fitted together after cooling. Further, inner sleeve is compressed by the outer sleeve to extend axially. During rotation of shaft, the axial extension of inner sleeve is reduced because the radial expansion of outer sleeve is larger than that of inner sleeve due to an thermal expansion coefficient of outer sleeve larger than that of inner sleeve. This can reduce prestress of bearings without degrading a rigidity thereof.

It can achieve the economy of smaller size and lower cost by using the multi-resolution CCD sensing device according to the invention, thereby increasing scanning speeds at lower resolutions.

Abstract: A microcontroller has a nonvolatile memory that originally stores program code and has free space. When part of the program code needs to be modified, that part is disabled, and modified program code is stored in the free space. The modified program code is executed in place of the disabled program code. Program code can be disabled by changing instructions to a designated instruction, by storing the address of the disabled program code in the nonvolatile memory and loading this address into a disabled code detector, or by deleting the address of the disabled program code from an address list in the nonvolatile memory and adding the address of the modified program code to the list. In this way, the program stored in even a one-time-programmable microcontroller can be changed to meet altered specifications or correct program bugs.
