Title: Method for compensating wavelength dispersion in optical transmission line
Inventor: HIRONISHI KAZUO
IPC: H04B10/2507
Filed: 1988-07-20
Abstract: PURPOSE:To prevent wavelength dispersion of an optical pulse signal by allowing the polarized planes of an optical pulse signal having shorter and longer wavelengths lambdaS, lambdaL to be intersected orthogonally with each other and inserting a wavelength dispersion compensation device cancelling a time difference between lights of the wavelengths lambdaS, lambdaL pass through an optical path. CONSTITUTION:A pulse signal is sent from an optical transmitter 1 to an optical transmission line 3 via a wavelength dispersion compensation device 10 and received by an optical receiver 2. The wavelength dispersion compensation device 10 consists of an optically rotatory device 11 and an optical path system assembly 20. The optically rotatory device 11 rotates the light so that the polarized plane of the pulse signal with a short wavelength lambdaS and the polarized plane of the pulse signal with a long wavelength lambdaL are intersected orthogonally with each other. The optical path system assembly 20 consists of polarized separation splitters 21, 22 placed with a tilt of 45 deg. with respect to a radiating light from the optically rotatory device 11 and mirrors 23, 24, propagates the output of the short wavelength lambdaS straightforward and allows the output of the long wavelength lambdaL to be detoured, thereby inputting the light of both wavelengths simultaneously to the optical receiver 2. Thus, the wavelength dispersion of the inputted optical pulse signal is suppressed.

Abstract: PURPOSE:To reduce a floating capacitance between a wiring layer and a silicon substrate, and obtain a semiconductor device having a high integration degree and capable of high speed operation, by arranging, in a field region, a silicon oxide film which is formed in the self-matching manner in the range of width of an isolation trench, and has a thickness larger than insulating films on an element region. CONSTITUTION:On the surface of a semiconductor substrate 1 in the title device, an element region B and a field region A are formed and isolated by an isolation trench 4 whose inside is filled with polycrystalline silicon. A silicon oxide film 10 is formed in the field region A, in the self-matching manner in the range of width of the isolation trench 4, and the thickness is larger than the thicknesses of insulating films 2, 3 on the element region B. For example, after the silicon oxide film 2 is formed on the silicon substrate 1, and the silicon nitride film 3 is deposited, the trench 4 is formed and then a channel stopper layer 5 is formed. A silicon oxide film 6 is formed on the side surface and the bottom surface of the trench 4, and the inside of the trench is filled with polycrystalline silicon 7. After that, oxidizing is performed by using the silicon nitride film 3 as a mask, and the thick silicon oxide film 10 is formed on the upper part of the polycrystalline silicon 7 and on the field region A.

IPC: G10L19/04
Filed: 1990-07-09
Abstract: PURPOSE:To encode a voice signal into a signal of high quality at a low bit rate with a relatively small arithmetic quantity by finding the best gain in each repetitive section when the delay time of an adaptive code vector is shorter than subframe length. CONSTITUTION:The system consists of an LPC analyzer 10, a subframe divider 120, a weighting filter 130, an adaptive code book unit 140, a sound source code book unit 150, a sound code book unit 180, an adaptive code book unit 190, a playback filter 200, etc. Then when the delay time of an adaptive code book is shorter than the predetermined subframe length, a delay time and a gain in each repetitive section are found at the time of repeating a sound source signal of delay time as many times as predetermined. In another way, the delay time, the gain in each repetitive section, a sound source code vector, and the gain of the sound source code vector are found so that the mean square error of the whole subframe becomes minimum. Consequently, excellent voice encoding of good sound quality becomes possible with a relatively small arithmetic quantity at <=8kb/s.

Abstract: PURPOSE:To reproduce an accurate signal by eliminating cross talk from adjacent tracks when the track density of a reproducing only disk is to be increased. CONSTITUTION:A target information track 2b is irradiated with a central light beam 3b to be emitted from an optical head 4, while two information tracks 2a and 2c two other light beams 3a and 3c respectively. A focus control and a tracking control are carried out by the central light beam to perform accurate positioning. Reflected light corresponding to this is independently detected by the head 4, and an information pit 1 on the information track 2 corresponding to this is detected. A signal is detected based on the presence of the pit 1 and the size of a reflected light quantity from a disk. This detecting signal is inputted to a cross talk canceler 5, and after it is subjected to filtering processing, an information pit on the target information track 2b corresponding to the light beam 3b is accurately detected. By this method, the signals corresponding to the target information track and the adjacent information tracks can thus be detected.

Abstract: PURPOSE:To permit displaying of accurate current positions on a plane map even if a vehicle travels on roads having grades and undulations by using an inclinometer in which a rotating angle accelerometer and a calculator are used in combination. CONSTITUTION:The output alpha of an accelerometer 1 is expressed by alpha=alpha +alpham, where in alphatheta is the acceleration component of the terrestrial gravity that the accelerometer 1 detects because the axis in the forward and backward directions of a vehicle or the like is inclined by the angle theta from horizontal and alpham is the acceleration in the forward  and backward directions when the vehicle travels. 2 is an angle accelerometer which detects the rotating angle accelerations of wheels. To determine a desired angle theta of inclination, a digital calculator 3 is used, and the angle theta of inclination determined by the same is displayed on a display device 4. The calculated angle theta of inclination is used for calculating the horizontal component VH=Vcostheta of a speed V. The VH is further resolved by using northward components, eastward components, and the azimuth of  the vehicle, which are respectively integrated with time, and the northeast components of the moving distances from the starting point are determined. The current values of the respective components are displayed on the map of a matched scale, whereby the correct current position is displayed on the map.

Title: Dynamic burn-in method for microcomputer with prescaler
Inventor: KIKUCHI TADASHI
IPC: G06F11/24
Filed: 1984-08-31
Abstract: PURPOSE:To apply a test pattern in common to many ICs and to attain a burn-in action by supplying clocks until the state of a prescaler of a microcomputer can fetch an instruction. CONSTITUTION:A rest switch 10 turned on to clear a counter 3 and to reset monostable multivibrator 2. Thus the CLK of a clock terminal 9 is applied to the Extal of a CUT1 through NAND gates 5 and 6. When an F/F of a prescaler of the DUT1 can fetch an instruction, a terminal E(IRU) of the DUT changes to H from L. Then an input is supplied to the input B of the multivibrator 2. The output Q of the multivibrator 2 is changed to H from L, and NAND gates 4 and 5 are kept closed. Thus the supply of clocks is stopped to the DUT, and the F/F of the prescaler is put under a waiting mode in an instruction fetch enable state.
