Title: Waveform detector and detection method
Inventor: YOSHIDA KAZUYOSHI
IPC: G01R23/16
Filed: 1995-06-16
Abstract: PURPOSE: To obtain a waveform detector which can detect an AC waveform accurately. CONSTITUTION: An AC voltage waveform is inputted through an input means, i.e., a PT1, and passed through a low-pass filter 2 for removing high frequency components except those on the order of 50Hz. The AC input voltage waveform is sampled for 50ms at a clock of 25.6kHz from a sample clock output circuit 5, thus obtaining a sample of 2.5 periods. Two zero-cross are then determined, based on the sampled data, and a half period is calculated followed by calculation of frequency. A decision is made whether the calculated frequency is higher than 49Hz but lower than 51Hz and the data is invalidated if the frequency is lower than 49Hz or higher than 51Hz. Subsequently, resampling is repeated 512 times using Newton interpolation until the sampling interval becomes 1/512 of a period, thus calculating a resampling data.  The resampled data is subjected to fast Fourier transform through an FFT processing means thus determining the content rate of harmonics in power system and a reverse effective value.

Title: Production of silver halide photographic emulsion and silver halide photographic sensitive material
Inventor: NAGAOKA KATSURO
IPC: G03C1/035
Filed: 1989-06-14
Abstract: PURPOSE:To obtain the silver halide photographic emulsion having a high sensitivity and graininess by subjecting a core particle to a chemical sensitization and then forming a shell thereon in the presence of a tetrazaindene compd. CONSTITUTION:After the core particle is subjected to the chemical sensitization, the shell is formed thereon in the presence of the tetrazaindene compd. The tetrazaindene compd. is preferably made to exist in the emulsion in the range of 10<-1> to 10<-5>mol range per 1mol silver halide contained in the emulsion. While the amt. of the tetrazaindene compd. to be added largely affects the latent image distribution from the surface of the silver halide particle to the inside, the optimum amt. thereof is properly increased or decreased within the range of the addition amt. by the pAg, pH, temp., etc., at the time of further growing the core. The silver halide photographic emulsion which has the high sensitivity is obtd. without impairing the graininess at the time of spectral-sensitizing.

Title: Alarm cell detailed information output device
Inventor: ONO HIDEAKI
IPC: H04L12/24
Filed: 1996-06-12
Abstract: PROBLEM TO BE SOLVED: To output detailed information of a fault to an external device on request of a maintenance personnel. SOLUTION: An alarm cell detection section 51 identifies an operation and management (OAM) alarm cell from other cells and stores details information of the alarm cell to a detailed information storage section 53 for each connection. When the detailed information is requested from an external device 40 in this state, an external interface 54 reads the detailed information stored in the detailed information storage section 53 and sends the information to the external device 40 to inform it to the maintenance personnel. When a connection to be captured is instructed from the external device 40 via an external interface 64, an alarm cell detection section 61 extracts an alarm cell (by one cell) of the connection subject to capture instruction and stores it to a latch circuit 63.  When the detailed information by one cell is latched in the latch circuit 63, the external interface section 64 sends it to the external device 40 to inform it immediately to the maintenance personnel.

Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a variable period signal generating circuit that is configured to reduce the circuit scale and to vary not only a period of a signal but also a duty factor. SOLUTION: A generating circuit is provided with a load input setting section 1, a counter 2, a comparison value setting section 3, a comparison detection section 4, a timing adjustment section 5, and a basic clock generating section 6.

The count determines a period of an output signal from the variable period generating circuit. The comparison detection section 4 compares the value set by the comparison value setting section 3 with the count from the counter to provide an output of L/H level. The duty factor is freely changed depending on the setting value by the setting section 3.

Title: Black/white converting method for picture data
Inventor: ISHIKAWA TOMOKO
IPC: H04N1/46
Filed: 1990-06-13
Abstract: PURPOSE:To enable black/white conversion so as to keep the continuity of a color and to follow up the instability of a video signal by calculating a white level and a black level after separating an arbitrary picture data into a Y-M-C component or an R-G-B component, and executing the black/white conversion according to these levels. CONSTITUTION:The arbitrary picture data is separated into the Y-M-C component, and the number of gradations is expressed by any suitable numerical value. When the black/white conversion is not executed, the separated Y-M-C component is printed white maintaining the number of gradations as it is. On the other hand, for the black/white conversion, the black level is subtracted from the number of gradations in each saparated YM-C component, and the white level is added to the value so as to define the value as the number of respective gradations. Therefore, printing is executed after exchanging the black level and the white level. Thus, the black/white conversion is executed without fixing the white level and the black level and limiting the picture of the complete white level and the complete black level, the continuity of the color can be kept, and the instability of the video signal can be followed up.
