Title: Alarm display system
Inventor: TSUKAGOSHI TAKASHI
IPC: H04B10/077
Filed: 1988-03-11
Abstract: PURPOSE:To eliminate the difference among display methods of an alarm display element in a system by blinking this display element with a code error alarm and then turning on the same alarm display element continuously with an optical input break alarm respectively. CONSTITUTION:A normal optical input level is gradually reduced and a MINERR alarm signal which is transmitted at occurrence of a small number of code errors is produced at a time point t1. Then an alarm display element 14 blinks in a cycle T2 via the ON/OFF actions of a driving switching element 6c for display of the MINERR alarm. When the optical input level is reduced less, the element 14 blinks in a cycle T1 at a time point t2 via the ON/OFF actions of a driving switching element 6b for display the MAJERR alarm which is transmitted with a large number of code errors. When an optical input break alarm signal is produced when the optical input is broken at a time point t3. Thus the element 14 is always turned on with conduction of a switching element 6a for display of the optical input break alarm. Thus it is possible to eliminate the difference among display methods in a system and to simplify the decision of faults.

Title: Gear pump
Inventor: SAYAMA MASAYUKI
IPC: F04C2/14
Filed: 1985-03-25
Abstract: PURPOSE:To decrease the driving loss, by constituting a gear pump as making the meshing width between a pair of gears to be varied by a moving means which moves at least one of the pair of gears toward its rotating direction, so as to make it possible to control the discharge quantity in response to the rotation input whose value is bigger than the preset value. CONSTITUTION:A hollow space 19 is formed in a case 1, on the moving side along the thrust force working direction of a driven gear 13, and the inside diameter of this space 19 is a little longer than the outside diameter of the driven gear 13. A coned disc spring 21 is set in the hollow space 19, and this disc spring 21 is in contact with the driven gear 13 through a plate 23. When the rotating speed of the engine becomes higher than the preset value, the driven gear 13 is moved to the inside of the hollow space 19 as the thrust force of the driven gear 13 becomes stronger than the elastic reacting force of the disc spring 21. By this movement, the meshing width between a drive gear 7 and the driven gear 13 is decreased, and the quantity of oil discharged from a discharged port 15 is suppressed. Accordingly, the increment of load which acts on the engine, is restrained, and such as the fuel consumption ratio can be improved.
