IPC: G06F13/42
Filed: 1988-12-29
Abstract: PURPOSE:To shorten a bus cycle at low cost by equipping a slave processor with a setting inhibiting circuit which inhibits a set clock to a received data register and a setting inhibition signal generating means which generates a set clock inhibition signal from received data information. CONSTITUTION:Slave processors 2 and 3 are equipped with setting inhibiting circuits 25 and 35 which inhibit the set clock to received data registers 21 and 31 and setting inhibition signal generating means 26 and 36 which generate the set clock inhibition signal from the received data information.

Title: Method for treating organic wastewater
Inventor: KOBAYASHI MITSUHIRO
IPC: C02F3/10
Filed: 1994-12-22
Abstract: PURPOSE: To strip off mold which grows in a filter bed and is difficult to peel off and growing fungus bodies before they fix on the filter bed by aerating intermittently through groups of air diffusion pipes of more than one series which are installed on the lower surface of a fixed filter bed and intensifying aeration sharply. CONSTITUTION: Pressurized air supplied through a main pipe 8 connected with a blower B reaches an air diffusion pipe 5 through an air feed pipe 7 and then is discharged from pores toward the bottom surface of a filter bed. Besides, drainage is introduced into a treatment tank 1 from an inlet 12. The pressurized air is sent to the air diffusion pipe 5 by opening the first valves 9a, 9b and the second valves 10a-10d. In this process, by changing over the first valves 9a, 9b or the second valves 10a-10d, the volume of diffused air from a certain group of air diffusion pipes is increased, and the volume of diffused air from the remaining groups is increased in sequence. In this way, an intermittent, high speed upward current is formed in the filter bed to strip off mold and growing fungus bodies before they fix on the bed.

Title: Standard signal detection device
Inventor: HASHIMOTO MASARU
IPC: H04N17/00
Filed: 1987-12-28
Abstract: PURPOSE:To decide the relation of frequency interleave with high accuracy by detecting whether the relation of a color burst signal cycle and a synchronizing signal cycle satisfies a condition recorded in a standard according to an inputted video signal or not. CONSTITUTION:Based on the color burst signal cycle, the synchronizing signal is delayed corresponding to the synchronizing signal cycle recorded in the standard of the inputted video signal or in the integral number folds cycles of it and the phase difference of the synchronizing signal (a) and (b) before and after the delay is detected. Based on the color burst signal cycle, the delay time of the synchronizing signal is set so as to be one horizontal scanning term or one vertical scanning term recorded in the standard or the integral number folds of these terms. As a parameter recognizing the relation of the frequency interleave of the inputted video signal, not only the relation of the color burst cycle and the synchronizing signal cycle but also the phase change of the synchronizing signal (continuity) based on the color burst signal cycle is used. Thus, the inputted signal is decided whether it coincides with the standard or not with the high accuracy.

Title: Deflection yoke
Inventor: KUWABARA YASUNAGA
IPC: H01J29/76
Filed: 1992-12-16
Abstract: PURPOSE:To eliminate a VCR narrow without causing the movement of deflection center of a deflection yoke. CONSTITUTION:Magnetic field-emissive portions 11a of a coma collector 11 are arranged parallelly with the rectilinear portion of an in-line type cathode-ray tube, and magnetic field collecting portions 11b thereof are respectively arranged opposite the end face of a ring-shaped core 3 on its electron-gun side so that it can absorb a leaky magnetic field 9a emitted from the same end face. The magnetic field collecting portion 11b can thus absorb a barrel magnetic field generated at the end face of the ring-shaped core 3, consequently this portion can be prevented from making any deflection in the barrel magnetic field, and instead, a magnetic field-emissive portion 11a can consequently generate a stronger pincushion magnetic field so that deflection sensitivity to a central electron beam can be improved more efficiently. A VCR narrow can also be eliminated without causing the movement of deflection center of a deflection yoke and a neck shadow.
