Title: Runback device for load of station in water-cooled generator
Inventor: TAKAHASHI KENJI
IPC: H02H7/06
Filed: 1980-10-08
Abstract: PURPOSE:To maximize active power within runback limit value by limiting load power within an allowable operation range while bringing reactive power to zero when cooling water is abnormal. CONSTITUTION:The detected output of an abnormality detector 12 for cooling water, i.e. runback signals, is inputted to respective another input of the first-third and gates 14-16. When armature currents exceed a predetermined limit, load is run back by the output of an armature current detecting circuit 11. When reactive power is detected by means of a reactive power detector 13, a Var is run back in response to the lead and lag. Accordingly, the maximum active power can be obtained even at the time of runback.

Filed: 1979-11-02
Abstract: PURPOSE:To permit the processing of the work extent which has been deemed hard to attain by a ultraviolet-ray exposure method, without using expensive devices by interposing a polyimide resin film between the work and photoresist films. CONSTITUTION:A polyimide resin film 3 is formed on an SiO2 film 2 and a pattern consisting of photoresist films 4 is selectively formed on the film 3. Next, the film 3 is selectively removed by employing the films 4 as masks. Next, the removal of etching is selectively applied to the film 2 by employing the film 3 pattern as a mask.

Title: Electrophotographic device
Inventor: TANAKA TATSUO
IPC: G03G15/16
Filed: 1984-07-09
Abstract: PURPOSE:To improve the transfer efficiency by a simple means which is stable even in long-period use by providing a means which applies a charge having the same polarity with a charge given to a developer between the developing part and transfer part of the electrophotographic device. CONSTITUTION:An electrostatic charging part 3, exposing part 4, developing part 5, and transfer part 8 which transfers a visual image formed by development to a transfer member 7 moving as shown by an arrow 6 are arranged in opposition to a cylindrical photosensitive body 1 in its rotating direction shown by an arrow 2. A device 9 which applies a charge having the same polarity with the developer is provided between the developing part 5 and transfer part 8. For example, the electrostatic charging part 3 gives a plus charge to the surface of the photosensitive body 1 and gives a minus charge to a developer (toner). In this case, when a minus charge is applied by the device 9, a plus charge remaining on the surface of the photosensitive body is neutralized even after an exposing process and the amount of minus charges that the developer has is increased. Consequently, the amount of the developer transferred to the transfer member 7 given a plus charge at the transfer part 8 is increased, thereby improving the transfer efficiency.
