Title: Exhaust equipment of engine
Inventor: EGUCHI NOBUJI
IPC: F01N1/06
Filed: 1983-04-30
Abstract: PURPOSE:To effectively suppress noise which is produced by pulsated exhaust gas flowing through an exhaust pipe by regenerating the pressure of exhaust gas inside the exhaust pipe which is detected by a sensor in the form of a pressure wave having a reverse phase and sending the pressure wave into the exhaust pipe. CONSTITUTION:A pressure sensor 6 which is positioned at the upstream side of an exhaust pipe 4 detects an exhaust pressure. Because of sequential explosions by burning inside the cylinders of an engine 1, a plurality of pressure waves are produced at the upstream side of the exhaust pipe 4 and the varying pressures are detected by the pressure sensor 6. The detected output is reversed by a phase reversing circuit 7 and then sent to an amplifier 8. Resulting pressure waves having a phase reverse to said detected output are sent into the exhaust pipe 4 by a diaphragm 10 which is driven via an electromagnetic solenoid 9 by the amplifier 8. Cancelling the pulsated exhaust gas by the pressure waves having the reverse phase may dissolve the problem of noise of exhaust gas which is emitted from the wall of the exhaust pipe 4.

Abstract: PROBLEM TO BE SOLVED: To avoid instable combustion by experimentally detecting a vibration zone by after-burn to adjust the richness of the fuel from each of primary and secondary flows so as to avoid the vibration zone in a turbo jet engine having an after-burner. SOLUTION: A turbo jet engine for aircraft comprises an after-burner which has primary and secondary flows and in which mixture is injected, at an adjusted ratio, from a primary richness point or a secondary richness point or all richness points of each flow. In this case, the richness of fuel in the primary and secondary flows and a gas pressure inside an after-burner duct are varied in the different operating conditions of an engine and different after- burning operating areas so as to experimentally determine the zones where vibration frequency occurs. Then, the richness of fuel from each flow is distributed to avoid the vibration zone, and the secondary richness is adjusted as a function of the primary richness.

Title: Overvoltage protective circuit
Inventor: HIRASAWA KAZUO
IPC: H01L21/822
Filed: 1994-04-15
Abstract: PURPOSE:To enhance the non-breakdown limit of an IC by a method wherein a current flowing in a switching element for a protective circuit is limited to a value at which the switching element is not broken down. CONSTITUTION:A constant-current circuit 1 is connected in series with an emitter for a transistor 8 in an overvoltage protective circuit. When a noise voltage which is applied to a VCC 3 exceeds the Zener voltage of a Zener diode 6, the Zener diode 6 is set to continuity. When a voltage generated across both ends of a resistance 7 by this continuity current becomes larger than the base ON-voltage of the transistor 8, a base current flows, and the transistor 8 is set to continuity. As a result, a bypass current flows across the VCC and a GND so as to function as a protective circuit. At this time, a current flowing in the transistor 8 is set in such a way that a value set in the constant-current circuit 1 becomes an upper limit. Consequently, when the upper-limit current value is set at the maximum allowable current value or lower of the transistor 8, the transistor 8 is not broken down.

Abstract: PURPOSE:To enable both sides of a sheet to be copied under a favorable condition by configuration a device in such a way that a sheet detecting means is provided along sheet conveyor paths to detect the sheet, simultaneously, a suspension/holding means is also provided so as to suspend the rotation of a pair of discharging rollers and allow the time for suspension to be held. CONSTITUTION:A sheet S, one side of which has been copied, is conveyed with its copied surface facing upward to an outer section of a printed image forming device main body by means of normal rotation of a pair of discharging rollers 33 based on normal rotation of a normal/reverse driving means 43. And when the sheet S is detected by a sheet detecting means 35, a suspension/holding means A is actuated. This allows the sheet to be suspended while the rear end of the sheet is held by a pair of discharging rollers 33. This enables an operator to check printed images during the period of time when a pair of discharging rollers 33 is suspended. Subsequently, the suspension/holding means is released either by a timer T which is activated after the specified amount of time has elapsed, or by a start switch St which is manually turned on by the operator allowing a pair of discharging rollers 33 to rotate reversely. This, furthermore allows the sheet, one side of which has been copied, to be conveyed to the device main body again permitting the other side of the sheet to be copied.

Abstract: PURPOSE:To perform monitoring and suppression of pulsating combustion with high precision, by a method wherein the relation between the detecting level of a vibration detector and a combustion air amount, and between a fuel amount and a heat generating amount including other factor amount related to pulsating combustion are determined by multivariate analysis, and fuel and air to be supplied to a furnace is variably controlled. CONSTITUTION:A noise level is continuously measured by means of a low frequency noise meter 31, and averaged and stored in a control device 30. From outputs from flow meters 20, 21, and 22 located in a combustion air line 19, combustion air is determined, and based upon an output from a flow meter 17, a C-gas flow rate is determined. Based upon the outputs from an ammonia concentration meter 13 and a flow meter 14, the amount and a flow rate of ammonia are determined, and a degree at which a factor amount thereof is related to the noise level of a furnace is determined by multivariate analysis to store it in the control device 30. The amount of air fed from the line 19 is computed so that a ratio between C-gas and ammonia combustion air becomes approximately 1, 0, and an opening regulating signal is outputted to flow rate regulating valves 23, 24, and 25 to control a flow rate. In which case, when a low frequency noise level exceeds a target frequency noise level, an opening regulating signal is outputted to a flow rate regulating valve 15 located in a duct line 11, and an ammonia vapor flow rate is varied and controlled to a value lower than the specified level.

Abstract: PURPOSE:To obtain an optical writing device which has less occupying capacity including a space required for forming an image, and integral structure, and is conveniently handled by using a refractive index distribution type self- convergency glass as a part or the whole of a vacuum vessel. CONSTITUTION:An anode electrode 3 is constituted so as to transmit light, the refractive index distribution type self-convergency glass 11 is used as a part or the whole of a sealing vessel 2.
