Patent JP-H02218269-A (JP)
Title: Picture processing unit
Inventor: TANIMIZU HIROMI
IPC: H04N1/40
Filed: 1989-02-20
Abstract: PURPOSE:To surely discriminate a picture element as a black one even when an original of the density of the black picture element is thin by discriminating the density of a black level picture element depending on the mean value of the maximum value and the minimum value of levels before the discrimination of a black level signal and varying the threshold level when the density is discriminated to be thin at a prescribed scanning region. CONSTITUTION:A maximum value of gradation in a prescribed unit scanning area is stored in a maximum value latch circuit 15 among picture signals of a black level signal latch circuit 11 discriminated to be at a black level by a comparator 3 and a minimum value of gradation is stored in a minimum value latch circuit 16. When the reading of the unit scanning area is finished, an averaging circuit 17 reads a picture signal respectively from the maximum value latch circuit 15 and the minimum value latch circuit 16 and obtains a mean value. When the part of an original with thin black density is read, a unit scanning area number (d) reaches a count reference value S2 as the result of comparison by the comparator 23. The comparator 23 at this point of time inputs a control signal to a threshold level circuit 4. The threshold level circuit 4 receives it and changes the 1st threshold level T into a 2nd threshold level C closer to the white level.

Title: Buffer type gas-blast circuit breaker
Inventor: INOHARA TOSHIAKI
IPC: H01H33/70
Filed: 1990-02-21
Abstract: PURPOSE:To restrain deterioration of dielectric strength and breaking performance to the minimum at the time of exposure to an arc by making a nozzle of a tetrafluoroethylene resin. CONSTITUTION:A nozzle for a gas circuit breaker is made of a tetrafluoroethylene resin 1 filled with a magnesium oxide 2. A filling amount of the magnesium oxide 2 mixed into the resin 1 is 20vol% or less, and an average particle diameter thereof is 10mum or less. Upon irradiation of arc energy 3 to the nozzle, a light reflection coefficient is so high that most of the energy irradiated to the nozzle can be reflected to become reflected light 4 which cannot intrude into the nozzle. Although only a little amount of arc energy 5 intrudes into the nozzle, the energy 5 can be speedily diffused because of a remarkably high thermal conductivity of the magnesium oxide, thereby preventing any concentration of heat on a local portion.

Title: Recording and reproducing device for low-band-converted chrominance component
Inventor: ABE KENJI
IPC: G11B5/027
Filed: 1985-02-28
Abstract: PURPOSE:To minimize stains in a main signal by setting the phase pattern of the recorded chrominance components in such a relation that the crosstalks from the magnetic tracks on right and left sides are offset with each other. CONSTITUTION:In case where the reproducing is executed by using a broad magnetic head, because the crosstalk occurs not only from the magnetic track of the main signal but from the ones on right and left sides, the detecting signal S is: S = (main signal + crosstalk from lefthand track + crosstalk from righthand track). When C2 of a magnetic track C is reproduced by a broad magnetic head, the reproduced signal is: SA=[ (C2)+ (B1)+ (D3)], and in case of C3: SB=[ (C3+ (B2)+ (D4)]. By setting the crosstalk from the heads on both sides with an equal quantity, the said crosstalks are offset with each other to attain SA=[ (C2)], SB=[ (C3)], and only the main signal is reproduced.

Title: Vacuum valve unit
Inventor: OTSUKA TETSUSHI
IPC: E03F5/22
Filed: 1997-02-24
Abstract: PROBLEM TO BE SOLVED: To prevent a sewage trap in a house from being broken due to operation of a vacuum unit by providing a gate valve that closes when the vacuum valve is open in a sewage inflow pipe. SOLUTION: The valve 10A of a gate valve 10 is provided at the end face of the inflow sewage port 100A of a sewage inflow pipe 100 in an openable manner through a hinge 11, the air inlet 117A of a ventilation pipe 117 is arranged in opposition to the gate valve 10. The gate valve 10 is closed by pneumatic force f3 flowing into a sewage tank from the ventilation pipe 117 when air is sucked to a vacuum sewage pipe when the vacuum valve is open. The breakage of a sewage trap is attributed to air suction force applied to the sewage inflow pipe 100 communicating with the sewage trap in a house when the vacuum valve is open.  Therefore, it is possible to prevent air suction force from extending to the sewage inflow pipe 100 and to protect the sewage trap against breakage by closing the gate valve 10 at the time of air suction after sewage is sucked to the vacuum sewage pipe due to the opening of the vacuum valve so that the sewage inflow pipe 100 may be blocked.

Title: Jamming backup apparatus
Inventor: NIWA YUICHI
IPC: G03G15/00
Filed: 1990-02-20
Abstract: PURPOSE:To increase the processing speed of a printer by temporarily prohibiting the sending of the interruption signal from a printer engine to a controller when the generation of paper jamming is detected and storing the data sent from the controller in a memory means. CONSTITUTION:When paper jamming is generated, an engine 3 stops printing operation to generate an interruption signal and stops a synchronous signal to inform paper jamming to a jamming backup apparatus 5 on the basis of a status signal. A jamming detection means 11 sends a jamming detection signal to a transmission prohibiting means 12 which in turn temporarily prohibits the sending of the interruption signal to a controller 2 and holds printing as it is without changing the status signal to paper jamming. The controller continuously sends a dot signal by one page and the dot signal is stored in an RAM 10 as it is. When the storing of the dot signal is confirmed, the transmission prohibiting means 12 releases the prohibition of the transmission of the interruption signal to inform paper jamming to the controller 2. The controller 2 displays paper jamming and, when jammed paper is removed, the dot signal stored in the RAM 10 is sent out to the engine 3 to reopen printing.

Title: Ink jet recording device
Inventor: YOSHIDA KAORU
IPC: B41J2/015
Filed: 1981-03-20
Abstract: PURPOSE:To detect a signal corresponding to a difference in voltage between the normal state and the high voltage down state by a device wherein an amplifier for the  signal detecting the down in high voltage applied to deflecting electrodes is provided  with a transmission delay circuit, and the amplifier issuing output corresponding to the  difference between output voltages from a delay circuit and the former amplifier is connected thereto. CONSTITUTION:Voltage across a resistor 25 through which the primary current of a  high voltage source 1 passes is amplified by an amplifier 26. When there occurs a high  voltage down at time t1, voltage at point (a) varies from V5 to V4 as shown by A. At  point (b), voltage V7 varies slowly of V6 under the charging action due to a resistor  R10 and a capacitor C1, as shown by B. With resistance values R11 and R13 having the  relationship of R11=R13, an amplifier 30 issues output in the inverted form of variation  at the point (a), as shown by C. Then, this variation output is fed to a comparator 28 and reference input -V8 is set about -V9/2, so that voltage at the point (a) becomes  to have a high level only for a period from t1 to t2, as shown by D. Since only a difference in the primary current of the high voltage source 1 between the normal state  and the high voltage down state of a deflecting electrode 3, such difference will not  subject to substantial variations even under variations in absolute value of the detected  voltage. As a result, a high voltage down can be detected positively.
