Title: Ultrashort pulse generator for electrical dust precipitator
Inventor: ANDO TAKASHI
IPC: B03C3/68
Filed: 1985-02-28
Abstract: PURPOSE:To attain the increase of the dust collection performance and the less energy consumption by making the voltage and the frequency of pulse variable and synchronizing the timing of the spark with the frequency of an inverter. CONSTITUTION:An electric power source 11 is rectified with a low-voltage rectifier 12 and DC is stored in a low-tension capacitor 13. In this case, the magnitude of the pulse can be made variable by adjusting a firing angle of a thyristor of the rectifier 12. DC stored in the capacitor 13 is converted into AC with an inverter 14 and fed to a primary side of a transformer 15. After converting the high-tension AC voltage charged in a secondary side of the transformer 15 into DC with a rectifier 16, DC is stored in a high-tension capacitor 17 and the pulse is fed to an electrical dust precipitator 19, each time a rotary spark gap 18 is ignited. The frequency of the pulse can be adjusted by the synchronized operation of both the frequency of the inverter 14 and a rotary electrode of the rotary spark gap 18.

Title: Data search control system
Inventor: KISHIDA KATSUMI
IPC: G06F17/30
Filed: 1991-02-08
Abstract: PURPOSE:To shorter the time required for data search and to improve efficiency for operating an information processor. CONSTITUTION:When an information processor 101 instructs a data search operation to a data searching device 102, it is judged whether a designated address exists in a range set in advance by an address detection circuit 110 or not and when it exists in the set range, a decoder 111 is driven. The decoder 111 decodes an input address signal, and when a relevant data search control part 103 exists, it is selected. Thus, when '1' is set to a specified value flag register, the specified value of a specified value generation circuit is read out as the result of data search and outputted onto a data bus 104. At such a time, since no search instructing signal 116 is outputted and no data search operation signal 109 is supplied, the search operation of the data searching device 102 is suppressed.

Filed: 1980-03-27
Abstract: PURPOSE:To directly measure the characteristics of photoabsorption of blood, by making possible the liquid to be measured immersible in a fine gap between a transparent body which adjusts the incidence and emission of light to an optical fiber and a reflecting body which is opposed to the transparent body. CONSTITUTION:A disc shape reflecting plate 3 is opposingly located to a glass  transparent body 2 which adjusts the incidence and emission of light to an optical  fiber 1, with a fine gap 5. The blood 4 filling the fine gap 5 forms a very short absorption optical path for the measurement. This light is transmitted the blood 4 in  the fine gap 5 through the transparent body 2 and reaches the reflecting plate 3,  and again is transmitted the blood in the gap and is transmitted to the photodetection system through the transparent body 2. Thus, the absorption characteristics of  the blood to be measured can directly be measured in real time, by the spectral  analysis of this light with the photodetection system.
