Title: Black level correcting circuit for video signal
Inventor: MATSUI SEIICHI
IPC: H04N5/243
Filed: 1991-01-18
Abstract: PURPOSE:To improve the contrast even when flare or the like takes place or in the case of AGC operation. CONSTITUTION:A clamp circuit 37 clamps a luminance signal Y so that a peak level of a black level pulse BP mixed by a pulse mixer 36 is fixed to a pedestal level. The peak level of the black level pulse BP corresponds basically to a minimum level (black floating level) Vb2 of the luminance signal detected by a black peak detecting circuit 33 and when the contrast detected by a contrast detecting circuit 40 is small, the level of the BP is set small or zero. Thus, the luminance signal level is adjusted in response to the black floating level and overcorrection is prevented.

Title: Apparatus for treating drain containing organic substance
Inventor: TAKANO HARUO
IPC: C02F3/08
Filed: 1992-02-03
Abstract: PURPOSE:To control the height of a development layer even when the specific gravity of the development layer should be changed by the growth or peeling of microorganisms deposited on developing carrier particles and to prevent the thickness of a sludge blanket layer from increasing above a necessary level. CONSTITUTION:The cross section of an accepting part of an upper layer 22 is made larger than that of an accepting part of a development layer 21. A corner part 22b, on which microorganism sludge is deposited, is installed in the lower part of the accepting part of the upper layer 22. The ascending flow velocity in a reactor 1 is reduced sharply at the changing point of the cross section, and the height of a development layer 2 is kept at the height of the accepting part of the development layer 21 even if the specific gravity of the development layer 2 should change. Excessive microorganism sludge can be removed by taking out the microorganism sludge deposited on the corner part 22b from an discharge port 24 to control the height of a sludge blanket layer 4. In this way, a treated water layer 8 is prevented from being contaminated with particles and sludge so that a circulating pump is protected from abrasion and other damages to keep normal development conditions. The treated water is also free from turbidity.

Title: High impedance detector circuit for defferential transmission
Inventor: HASHIMOTO KENICHI
IPC: H04L12/40
Filed: 1978-02-17
Abstract: PURPOSE:To secure the detection of the fact that the driving circuits are all in the high-impedance state in the differential binary transmission circuit without using a special power source nor the cable different from the data cable. CONSTITUTION:Terminal 63 is fixed to logic ''1'', and the micro voltage of, for example, 40mV is generated at reference potential generator circuit 59 to be applied to terminal 65 and 66. The signal line of the bus in the differential binary transmission circuit is connected to terminal 61 and 62. When the signal is being transmitted to the bus, the differential binary code is available. So the potential difference between two lines is equivalent to the signal amplitude which is usually much larger than 40mV. Accordingly, terminal 64 features logic ''1'' at all times. When the driving circuits connected to the bus are all put under the hihg-impedance state, the potential difference between the two lines becomes zero. Thus, terminal 64 features logic ''0''. In such way, the high-impedance state can be detected for the bus.
