Title: Exhaust gas damper
Inventor: HIGUMA KATSUTOSHI
IPC: F01D25/30
Filed: 1984-12-05
Abstract: PURPOSE:To prevent a reversal flow and an abnormal pressure increase when exhaust gas ducts are merged by providing a damper to the exhaust gas ducts that lead the burnt gas discharged from a gas turbine system to a smoke stack. CONSTITUTION:A compound cycle plant has a gas turbine system 10, a waste heat recovering boiler 20, a steam turbine system 40 and denitrification system 31. In such an arrangement, an exhaust gas damper 27 is disposed in an exhaust gas duct 25 from the waste heat recovering boiler 20 to a smoke stack 24. As an abnormal pressure increase in the exhaust gas duct can take place by the compressed air due to the racing gas turbine if a damper at the waste heat recovering boiler outlet is rapidly closed while the gas turbine is being tripped, the abnormal pressure increase is prevented by the rate of speed of the damper closure at the waste heat recovering boiler outlet and the action of the afore-said exhaust gas damper 27. Further, the burnt gas from the working gas turbine is prevented from reversing itself into the stopped gas turbine system.

Patent JP-H0198313-A (JP)
Title: Synchronizing circuit
Inventor: YAMADA KAZUMI
IPC: H03K5/00
Filed: 1987-10-09
Abstract: PURPOSE:To completely evade an abnormal output state caused due to simultaneous change in a data input and a clock input to a DFF by fetching a data signal to be synchronized into an SRFF(set reset FF) in the timing except the vicinity of state transition time so as to propagate the signal to the DFF of the next stage. CONSTITUTION:In giving a data signal to be synchronized from an input terminal IN, the one is given directly to an AND circuit 2 and the other is given to an AND circuit 3 via an inverter circuit 1. Then each signal is ANDed with a control signal phi1 and the result is fed to a set terminal S and a reset terminal R of the SRFF 4. In this case, the signal phi1 is retarded by a prescribed time by a clock signal phi0 to close the circuits 2,3 in the vicinity of the leading of the signal phi0 and no signal is applied to the FF 4 even when the data signal IN is changed for that time. Thus, a data input signal synchronized with the clock signal is outputted at an output terminal OUT.

Abstract: PURPOSE:To provide luminous efficiency several times larger than the case of the conventional discharge tube by forming a cathode with an electron emission element comprising a conductor substrate and the predetermined thickness of a dielectric film laid on the anode side surface of the substrate. CONSTITUTION:A conductor substrate 8 comprising a metal base film deposited on the surface of a glass substrate is provided, and a dielectric thin film 9 of 100Angstrom  to 1mum mainly composed of MgO is formed on the substrate 8, thereby forming an electron emission element.

The thin film 9 is applied with strong electric field by the amount of the charge and the potential of the substrate 8. As a result, electron emission starts, due to a tunnel effect and hot electron starting from the substrate 8 and penetrating the thin film 9 is emitted toward the anode 10. Upon reaching steady state, the electron emission is stabilized, and this stabilized state is maintained.

Title: Reproducing device
Inventor: YOSHINO KAZUO
IPC: H04N5/783
Filed: 1986-10-28
Abstract: PURPOSE:To prevent a picture just after the transition from a normal reproduction mode to a slow reproduction mode from noizing on its upper and lower parts by averaging a tracking error voltage at the time of a first still reproduction in the slow reproduction mode and controlling the next normal reproduction based on the averaged voltage. CONSTITUTION:A slow reproduction is carried out by repeating a still reproduction and a normal reproduction with a magnetic tape recorded with pilot signals for tracking together with video signals. When the magnetic tape is stopped in order to switch over from the normal reproduction mode to the first still reproduction of the slow reproduction mode, a tracking error voltage is averaged to obtain a voltage almost equivalent to the tracking error voltage during the slow reproduction, and the next normal reproduction is then controlled based on the obtained voltage. Consequently, no tracking error is occurred upon the slow reproduction just transited from the normal reproduction, thus preventing a picture from noizing on its upper or lower part.
