Title: Background elimination processing system for picture recorder
Inventor: ITO AKIHIRO
IPC: H04N1/40
Filed: 1990-05-31
Abstract: PURPOSE:To eliminate a background with a threshold level in response to each background density by setting a density area and a threshold level relating to each other, selecting the threshold level through the detection of the density area and using the threshold level so as to eliminate the background. CONSTITUTION:A threshold level 1 consists of plural threshold levels of representative background density, and a density area detection means 2 detects a background density of an input picture data through the comparison with each of the threshold levels 1. A threshold level decision means 3 selects an applied threshold level for background elimination processing and a background elimination means 4 discriminates whether or not the input picture data is larger than the applied threshold level and discriminates it to be a background when smaller and makes the input picture data zero, and decreases the picture a little for an area in slight excess of the applied threshold level when larger and outputs the input picture data while the data at a high density is kept the same. Thus, even when plural background densities exist like a patched original, the representative background density is detected at each area and the background is eliminated at an optimum threshold level.

Title: Communication control system
Inventor: INAO KIYOHARU
IPC: H04L12/42
Filed: 1985-07-02
Abstract: PURPOSE:To attain time division multiplex communication circulated always at a prescribed period without requiring any exclusive master node by sending a packet of a prescribed length sequentially from the upper stream when the right of transmission is opened after a reference packed is circulated. CONSTITUTION:A communication node S0 sends the reference packet being a reference at a prescribed period T cyclicly in the order of other communication nodes S1, S2, S3 via a communication line L. When the communication node S0 completes the transmission to the communication line L and opens the right of transmission, the downstream communication node S1 receives the right of transmission and sends a packet of prescribed length. When the communication node S1 completes the transmission of packet and opens the right of transmission, the downstream communication node S2 receives the right of transmission and sends a packet of prescribed length. Thus, the right of transmission is shifted sequentially in order from the upperstream communication nodes S1, S2, and the transmission of all the communication nodes S1-S3 is finished.

IPC: C21D1/09
Filed: 1992-06-05
Abstract: PURPOSE:To prevent generation of thermal crack by starting irradiation of high-density heating energy from a portion in the vicinity of a periphery of bottlenecks before cutting a center portion the bottleneck sandwiched between an intake port and an exhaust port, terminating the irradiation at a center portion, and cutting a crater to be generated by the irradiation. CONSTITUTION:In a casting process of a cylinder head, an intake port 2, an exhaust port 3, and a chamber port 4 are punched. Surface treatment is done from a starting portion (a) in the vicinity of a periphery of a bottleneck portion between the intake port 2 and the exhaust port 3 by means of remelting treatment. This treatment is done by irradiating TIG arc as high-density heating energy. TIG arc irradiation is carried out from the starting point (a) in the direction of arrows A1, A2 to A5, and terminated at a center portion. Even in case a crater is formed on the center portion, thermal stress is decreased at the center portion and the crater is removed by cutting in a recessed form. The trace of the crater does not remain, accordingly. It is possible to prevent generation of thermal crack which may caused by deterioration of a mechanical characteristic.

CONSTITUTION:A tungsten-rhenium thermocouple 2 for measuring the temp. of a crucible 1 of a molecular-beam source is directly led out to the outside of a vacuum tank 4 by an introducing terminal 3 for the thermocouple and connected to a compensating lead wire 5. Since this contact 6 is housed in a thermostat 7, constant thermoelectromotive voltage V is always caused. True thermoelectromotive voltage due to the temp. of the crucible 1 is obtained by subtracting this voltage V from the measured voltage in a controlling device 8. A power source 9 is controlled on the basis of this value. The output thereof controls the output of a heater 11 via a current introducing terminal 10 and the temp. of the crucible 1 is controlled. The temp. of a base plate 12 is similarly controlled as this. The temp. of the crucible 1 and the base plate 12 can be accurately controlled.

Title: Electrophotographic device
Inventor: KAMI HIDETOSHI
IPC: G03G21/10
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To easily remove discharge produced substance such as nitric acid ion attached to the surface of a photoreceptor without using a complicated means and to prevent the image flowing of an electrophotographic device by providing a toner cleaner for removing discharge produced substance ion caused by corona discharge in an electrifying means. SOLUTION: The cleaner 17 is brought into contact with the surface of the photoreceptor 11 where high molecular charge transporting substance is contained in the outermost layer most separated from a conductive supporting body so as to wipe out the discharge produced substance such as nitric acid ion or ammonium ion. Electric field is generated by electrification caused by the friction of the cleaner 17 with the surface of the photoreceptor 11, so that the discharge produced substance is moved to the cleaner 17. Since fiber sued for the cleaner 17 contains a radical having high polarity and a hydrophilic radical and absorbs moisture in the air, the discharge produced substance is easily moved from the surface of the photoreceptor 11 to the cleaner 17.  It is good to always bring the cleaner 17 into contact with the surface of the photoreceptor 11 and it is desirable to bring the cleaner 17 intermittently into contact with the surface of the photoreceptor 11.
