Title: Dc power source circuit
Inventor: NISHINO TOSHIO
IPC: G05F1/46
Filed: 1987-03-02
Abstract: PURPOSE:To enhance the economy of a DC power source circuit and to reduce the size and the weight of the power source by providing a switching element using a nonpolarized capacitor. CONSTITUTION:When a current flows from an AC power source 1 through a diode 3, the current flows to its output 7, and an electric energy is stored in a choke 4 and a capacitor 6 simultaneously. Thus, when an input voltage decreases or the current flows reversely to the diode 3, the current flows from the capacitor 6 to the output 7 to output a DC. In this case, the input current flowing through the diode 3 is arbitrarily controlled by utilizing a nonpolarized capacitor 2 and the diode 3. Thus, the magnitude of a resistor 8 determines the base current of a transistor 9, and the remaining charge of the capacitor 2 is determined by the corresponding collector current. As a result, the current amount flowing to the output is varied by the resistor 8, and the output voltage is also altered.

Title: Lighting system
Inventor: MOCHIMARU SHINJI
IPC: H01J61/38
Filed: 1992-03-03
Abstract: PURPOSE:To suppress the attachment of a pattering to a tube wall in the direction of a transmission plate even though a spattering is generated from the end edge, and to reduce a reduction of luminous energy owing to a blackening, by sealing the continuous surface of a cold cathode on the end of a discharge lamp and facing the surface to a light diffusion transmission plate. CONSTITUTION:In a cold cathode 10, a spattering of the electrode subatance is generated by a high cathode drop voltage. This spattering generates at the end edges 102a and 102b more than at the plain surface of a plate 102. As a result, the plain surface of the plate 102 is faced to a light-diffusion transmission plate 15, and the end edges 102a and 102b are provided in the direction to cross square to the transmission plate 15. As a result, the spattering is scattered to the left side and the right side to be attached to a bulb wall, and the amount attaching to the bulb wall in the direction from the cold cathode to the transmission plate 15 is reduced. Consequently, even though a blackening is generated, a brightness reduction of the light diffusion transmission plate is reduced, and the brightness distribution is prevented from dispersing.

Title: Roadside beacon system
Inventor: NISHIO MASAHIRO
IPC: G09B29/10
Filed: 1988-02-26
Abstract: PURPOSE:To detect the direction of a vehicle by synchronizing a sent data frame for 1st modulation with an amplitude-modulating signal for 2nd modulation. CONSTITUTION:The split beam antenna 8 of a roadside device has at least one couple of antenna elements which differ in main radiation direction. Then a 1st modulated wave signal which is modulated according to the sent data frame is divided into two and a 2nd modulated wave signal obtained by amplitude modulation with modulating signals which synchronize with the sent data frame and are set opposite in phase from each other is fed to the couple of antenna elements. A receiver mounted on the vehicle, on the other hand, receives sent signals from the antenna elements to extract the amplitude-modulated component, and demodulates the 1st modulated wave signal to restore the sent data frame. Further, a modulating signal which synchronizes with the sent data frame is regenerated with the restore sent data frame and its phase is compared with the phase of the amplitude modulated component to detect which area in the main radiation direction of the antenna 18 the vehicle is in.

Title: Image processor and image-processing method
Inventor: YAMAZAKI HIROYUKI
IPC: H04N1/40
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To prevent a conversion method of an input image from causing inability of analysis for add-on additional information by selecting an addition method which is proper to a selected image conversion method and adding a prescribed additional information to the image signal. SOLUTION: A received image signal 901 for each color is given to an image- processing section 902, in which 1st or 2nd dither processing is selectively conducted based on a dither processing designation signal 905. After the dither processing, the processed image signal is given to a dot pattern addition section 903. A ROM 906 stores three dot sets, and the adder section 903 adds a dot pattern to the input image signal, only if a color designation signal designates a luminance signal Y and does not add any dot pattern to M, C, Bk signals. Thus, additional information applies add-on to only part of colors that are hardly perceived by human eyes. Then the image signal to which the dot pattern is subjected to add-on is given to a laser drive section, by which printing is conducted.

Title: Reactor core monitor

Filed: 1992-03-03
Abstract: PURPOSE:To always make possible setting of right selection control rods by exactly and quickly alarming a modification time in the case where an operation area is enlarged and it is necessary to modify a selection control rod pattern in accordance with an operation point. CONSTITUTION:Points A-C on a straight line L are within the range of normal rated output operation, for instance, when operation is performed at a point A and two recirculation pumps trip, the thermal output and the flow of a reactor core are lowered down to another point (a) on a curve l1. But, when operation enters an unstable area R0 on the way, a selection control rod is inserted and the thermal output of the reactor core is controlled within the target output range of Pu-P1 for the area R1. In another selection control rd pattern, the thermal output of the reactor core is controlled in the range of Pu-P1 for the area R2. Before reactor start, in the case where input is performed in regard to the areas R1, R2 and when one of two modes 1(2), is selected, an alarm for pressing setting modification is given when the thermal output thereof is lower (higher) than a value indicating another curve l2. Thereby the modification of the selection control rod is quickly performed without any need of human monitoring in a necessary time and proper selection control rod can be set always.

Abstract: PURPOSE:To obtain a smooth voice by segmenting the generation time of each phoneme into plural time zones by phonemes constituting a syllable, specifying a phoneme parameter of the sectional area, etc., of an acoustic tube by the time zones, and interpolating the phoneme parameters according to a specific recurrence formula extracted from an exponential formula. CONSTITUTION:The voice channel of a human is regarded as an acoustic tube group and made to correspond to a circuit element group of surge impedance components, thereby simulating a voice according to the current wave at the output terminal of the circuit element group. Then the exponential function is not interpolated actually, but respective interpolation values are found by utilizing the recurrence formula shown by an equation I extracted from the function, so arithmetic processing is easy. Here, the initial values of respective parameters of the pitch, energy, and sectional area of each time zone are denoted as X(O), the initial value of a next time zone as Xr, a constant as k (>1), an (n)th interpolation arithmetic value as X(n), and time constants corresponding to respective parameters as D. Consequently, the smooth voice is obtained and a listener is given a natural feeling.
