Title: Exhaust feedback control method for internal- combustion engine for car
Inventor: KISHI NORIYUKI
IPC: F02M25/07
Filed: 1983-04-07
Abstract: PURPOSE:To enhance the acceleration characteristics immediately after starting by performing a control of the exhaust feedback in an internal-combustion engine of a car, wherein the control is so made that the exhaust feedback operational range for feedback of the exhaust gas to the suction passage shall be shrinked particularly when the speed change ratio of the transmission is large. CONSTITUTION:In order to control the amount of exhaust feedback in an internal-combustion engine 1 of a car, the exhuast gas is fed back via an exhaust feedback path 21 which puts the exhaust passage 11 in communication with the suction passage 2. The transmission ratio of a speed change gear 16a driven by the engine 1, the number of revolutions of the engine, and other engine operational parameters to represent the suction amount are sensed. The exhaust feedback operational range determined on the basis of the number of revolutions of the engine and other operational parameters for the engine shall be changed according to the transmission ratio of the speed change gear 16a, and the exhaust gas shall be fed back while the current data for such factors as abovementioned lie within the range which applies currently.

Abstract: PURPOSE:To use the interface device without damage of a function of a standard telephone terminal equipment by connecting the standard telephone set to a wired broadcast telephone line under the control of the telephone line interface device. CONSTITUTION:When a loop is closed with respect to line terminals L3, L4 by hook-off of a standard telephone set 15, a dial start command is given to a control section 147. The control section 147 detects the operating state of a telephone line 11 through a line polarity detection section 142. When the line 11 is idle, the control section 147 applies loop forming to the line 11 by using a trunk 144 to start a line circuit 161 of a wired broadcast telephone exchange 16. The circuit 161 inverts the polarity of the line 11 immediately and sends a dial tone from the exchange 16. The telephone line interface device 14 reads the polarity inversion of the line 11 by using a detection section 142 and sends a specific ID to a relevant device to the exchange 16 via the trunk 144. Then the device 14 sends a DT to the telephone set 15 via the trunk 141 and a line circuit 145.

Title: Transistor driving circuit
Inventor: KATSUYAMA KENICHI
IPC: H02M3/28
Filed: 1987-03-17
Abstract: PURPOSE:To improve the efficiency of power source energy, by proportionating a current which flows on the collector of a transistor to a base current, and operating the switching operation of the transistor in a non-saturated area. CONSTITUTION:A voltage between the collector and the emitter of the transistor 1 is increased by a diode group Da consisting of a prescribed number of diodes being connected to the base of the transistor 1 in a forward direction, and the transistor is operated in the non-saturated area. However, a collector current is detected by a winding N2, and the value of n2/n1 of respective winding n2 and n1 of the winding N2 and a winding N1 is permitted to flow on the winding N1, then, the base current is limited. Also, since the base current of the transistor 1 is driven by a transformer 2 by proportionating to the collector current, the base is decreased when the collector current is decreased. In such a way, since no unrequired large magnitude of current flows, it is possible to improve the energy efficiency of a power source.

Abstract: PURPOSE:To obtain a combustor, which enables to perform NOx decreasing combustion over the whole load by a method wherein the flow rate of combustion air is made variable in accordance with the flow rate of fuel supplied to the first stage combustion zone. CONSTITUTION:Fuel is supplied through fuel pipings 8 and 15 to the titled combustor.

Filed: 1989-03-16
Abstract: PURPOSE:To attain high density frequency multiplex by setting a frequency of a local oscillation light to a frequency being an intermittent frequency corresponding to a mark and a space of a coherent signal light. CONSTITUTION:A polarizer 3 applies linearly polarized light processing to one of a signal light and a local oscillation light 2 and applies circularly polarized light or an elliptically polarized light processing giving an equivalent phase difference to the linearly polarized light processing and the circularly polarized light processing to the other. A mark, space signal is demultiplexed from an output from the polarizer 3 with a 90 deg. hybrid circuit 8 via an optical coupler S or the like. In this case, the frequency of the local oscillated light 5 is set to a frequency being an intermediate frequency corresponding to the mark, space signal of the signal light 1 in a binary value subject to optical frequency digital modulation. Even when the local oscillation frequency is set so that the intermediate frequency is decreased as above by using the image demultiplex type receiver through the constitution above, the effect of the image component is not received. Thus, the frequency interval of the signal light is reduced and high density frequency multiplex is attained.

Title: Control device for molten steel in mold of continuous casting
Inventor: KODAMA MASANORI
IPC: B22D11/18
Filed: 1980-05-13
Abstract: PURPOSE: To decelerate the velocity of discharge flow against the increase in the rate of casting,  and to prevent breakout and corner cracking and to prevent the degradation in quality by disposing one of moving magnetic field generators on the outside surface of a mold for continuous casting in parallel with the molten steel flow discharging from the immersion nozzle of said mold.   
     CONSTITUTION: The descending flow 5 of the molten steel discharged from the discharge hole 3  of an immersion nozzle 2 increases the velocity of flow of the molten steel flow in proportion to  the increase in the discharge rate of the molten steel if the rate of casting of an ingot increases and  the rate of discharge of the molten steel increases. In order to regulate the velocity of this molten  steel, moving magnetic field generators 7 are installed in the positions where the outside surfaces  of the long side of the mold oppose to each other by way of the molten steel flow. The electric  power corresponding to the change in the rate of casting is supplied to the generators 7, whereby  the discharge flow of the molten steel is controlled to prescribed velocity. Although it has no  trouble to install the generators 7 on one side of the long side of the mold, it makes the controlling  of the velocity of flow more accurate and easier to dispose four pieces of the mutually opposing  generators 7 by way of the molten steel flow.
