Patent JP-H0366297-A (JP)
Title: Digital preamplifier, digital power amplifier and speaker system built-in amplifier
Inventor: ISHIKAWA SEIICHI
IPC: H04R3/04
Filed: 1989-08-05
Abstract: PURPOSE:To obtain an original audio signal not subject to signal processing as it is at a post-stage by converting a signal conversion coefficient or an amplitude conversion coefficient obtained at a frequency characteristic input means through the setting input thereto into a digital information signal in a digital preamplifier, mixing the digital information into an audio signal and transferring the result to the post-stage. CONSTITUTION:A frequency characteristic input means 4a of a signal control section 4 in a preamplifier 1 obtains a signal conversion coefficient applying signal conversion in matching with a characteristic entered by the operator. An amplitude input means 4b receives an amplitude deciding the level of a reproduced sound similarly and obtains an amplitude conversion coefficient to realize the expected amplitude. Both the coefficients obtained are converted in a form of a digital information signal by an input characteristic conversion means 4c. An input signal selection means 2 selects one of modulated digital signals inputted from plural digital signal input terminals and outputs the selected signal and an audio signal demodulation means 3a demodulates an audio signal from the outputted signal. A digital signal mixture means 3b mixes the demodulated digital audio signal and the digital information signal and a digital signal modulation means 3c applies again digital modulation to the resulting signal.

Title: Illumination angle adjusting method for vehicular headlamp
Inventor: YOKOYAMA SHINZO
IPC: B60Q1/06
Filed: 1991-07-19
Abstract: PURPOSE:To prevent a defect that light distribution is confused in correcting light distribution by synchronizing one side illumination angle variable speed with the other side illumination angle variable speed. CONSTITUTION:When absolute value alpha of difference between variable moving quantities of illumination angles of a right headlamp and a left head lamp becomes beta or more, variable action of illumination angle of the faster side headlamp in illumination angle variable speed is tempolarily stopped to wait till it becomes gamma or less. As a result of stepwise repeat of this to a necessary variable action quantity theta0, the illumination angle variable speed of the faster side headlamp is made to synchronize with the illumination angle variable speed of the slower side headlamp.

Title: Watch dog timer and microcomputer
Inventor: AZUMA HIDEJI
IPC: G06F11/30
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To easily provide debug of program development by simply permitting the operation and stop of a watch dog timer without performing troublesome connection. SOLUTION: A CPU 2 is connected through a ROM 3, a RAM 4, a peripheral circuit 5, a watch dog timer 6 and a system bus and writes a count initial value to the timer 6 in every prescribed cycle, operating according to a program stored in the ROM 3. The timer 6 reduces a count value one by one in every prescribe cycle when the count initial value is written from the CPU 2 and outputs a borrow signal to the CPU 2 when the value becomes zero. The CPU 2 accesses a CE generation circuit 9 of the timer 6 when it stops the timer 6 at the time of emulation. Because the circuit 9 outputs a CE signal with that, the counter function of a down counter 10 is stopped.

Filed: 1986-09-02
Abstract: PURPOSE:To obtain a favorable gradation corresponding to an image by setting a highlight point and/or shadow point as considering the size of the area of the part of an input video signal whose level is close to a highlight point and/or a shadow point. CONSTITUTION:In case a highlight area and that of the vicinity of the highlight, between 99% and 90% of a cumulative histogram, are large, a highlight point is set at a point of an input video signal level close to the 99%, but if the said areas are small, the highlight point is set at a point of an input video signal level distant from the 99%. As a result, such part of an input video signal as of a level close to a highlight point can be made of a favorable gradation corresponding to the area of the said part itself. The setting of a shadow point is executed similarly. Therefore, a gradation favorably corresponding to an image can be obtained.

Title: Detector for detecting contact of different frequencies

IPC: H02H3/50
Filed: 1995-08-11
Abstract: PROBLEM TO BE SOLVED: To provide a detector for detecting contact of different frequencies which can quickly and stably detect faulty contact of different frequencies from a beat-like waveform. SOLUTION: A detector for detecting faulty contact of different frequencies is provided with a fault contact frequency detecting section 1 which detects the current of an AC feeder circuit and discriminates whether or not the frequency of the current is a fault contact frequency by calculating the frequency from the waveform of the current by performing arithmetic processing based on a sampling theorem and a minimum operating current detecting section 2 which discriminates whether or not the level of the current is higher than that of the minimum operating current and ANDs the outputs of the detecting sections 1 and 2 and a continuous discriminating counter 4 counts the number of outputting times of AND.  When a low-level detecting period exists until the count value of the counter 4 reaches a prescribed value, the counter 4 holds the present count value and, when the current again starts to increase, starts counting from the held value. Therefore, the counting speed of the counter 4 can be increased, namely, the operating time of the counter 4 can be shortened and stabilized (uniformized).
