Abstract: PURPOSE:To shorten turn off time, by impressing a reverse bias voltage on a gate when a FET switch is put OFF. CONSTITUTION:A DC voltage 3 is impressed on a load 5 through a DC/DC converting unit 1 switched by a FET switch. The driving circuit of the FET switch is constituted of an ON/OFF circuit 2 thereof, a control circuit 4 having a control unit 20 and a TR21, a forward bias circuit 31 having another TR22, an electric power source circuit 32 and the like. The control unit 20 detects an output current flowing through a load 5 by a resistor R11 and outputs a pulse voltage having ON/OFF level. The pulse voltage is impressed on the forward bias circuit 31 and the electric power source circuit 32 generates DC voltages V1, V2 which are used as a forward bias voltage V1 and a reverse bias voltage V2 respectively. According to this method, the TR21 is put off and the reverse bias voltage V2 is impressed on the gate G of the FET switch when the polarity of the pulse voltage from the control unit 20 is negative.

Title: Operation test of by-pass valve of steam turbine plant
Inventor: TAKAHASHI MAKOTO
IPC: F01K9/04
Filed: 1983-04-15
Abstract: PURPOSE:To contrive to prevent high temperature steam from flowing into a condenser and consequently to improve the durability of the condenser by a method wherein the cooling water valve and the by-pass valve of a desuperheater are open in the above-mentioned order at the start of the periodical survey of the by-pass valve and closed in the order of the by-pass valve and the cooling water valve at the end of the survey. CONSTITUTION:When an operation test signal S0 is inputted to a valve control device 22, a change-over signal generator 30 issues a ''change-over to close side'' signal S6 in order to close a contact 28 and a ''valve open'' signal S4 in order to open a cooling water valve 15 to the valve 15. As a result, cooling water is jetted in a desuperheating part 12 under the condition that a by-pass valve 7 remains closed because of a contact 27 being open before the signal S0 is inputted. When the jetting pressure of the cooling water exceeds a set value, a ''change-over to close side'' signal S5 is outputted in order to close the contact 27. After that, the signal S0 is outputted as a ''valve open'' signal S3 so as to open the valve 7 in order to flow main steam through a desuperheating device 9 into a condenser 3. Next, at the end of the test, when the inputting of the signal S0 is stopped and accordingly the generation of the ''valve open'' signal S3 is discontinued and the valve 7 is closed and then the steam pressure flowing in the condenser 3 lowers below a set value, a change-over signal S8 opens the contact 28, resulting in not sending a ''valve open'' signal to a cooling water valve 15. Accordingly, the valve 15 is closed and consequently the condenser is protected.

Abstract: PURPOSE:To enable accurate measurement of a flow rate by a method wherein a flow rate conversion value showing the relation between the flow rate and an output signal of a flow rate detecting means is stored, with its natural nonlinear characteristic unchanged, in a flow rate conversion value storage means. CONSTITUTION:When a gas is used, an oscillation frequency of a fluidic oscillation element 3 is detected by an oscillation detecting means 20. In the case of an area of a small flow rate, the number of pulses corresponding to a flow velocity is detected by a flow velocity detecting means 21. A flow rate conversion value showing the relation with an output signal of a flow rate detecting means 19 is stored, with its natural nonlinear characteristic unchanged, in a flow rate conversion value storage means 22. A flow rate setting means 23 determines a flow rate on the basis of a coefficient stored in the storage means 22 and corresponding to the output signal of the detecting means 19 and of a detection signal. In another method, a flow rate value stored in the storage means 22 is searched for on the basis of the output signal of the detecting means 19 and the flow rate corresponding to the output signal is set. Then, the determined flow rate is added up to determine an integrated flow rate in an integrated flow rate computing means 24 and the value of the integrated flow rate is displayed 18.

IPC: C03C10/02
Filed: 1981-05-06
Abstract: PURPOSE: A fine powder of previously crystallized meta-phosphate glass is sprayed on the surface of formed meta-phosphate salt glass to effect the growth of the crystal from the crystal unclei of the fine powder, thus making it possible to produce meta-phosphate crystallized glass oriented in the one direction in a short time.  
     CONSTITUTION: A mixture of calcium carbonate and orthophosphoric acid is placed in a platinum crucible and heated at 1,200W1,300°C for 1W24hours. The raw materials are melted and glassified homogeneously, then cooled to form a plate or rod. A fine powder of previously crystallized meta-phosphate salt glass is sprayed on the surface, especially on the end surface of the formed glass. Then, the formed glass is heated again at a temperature lower than the softening point but higher the transition one in an atmosphere with a temperature gradient. Crystals grow from the crystal nuclei of the fine powder in hemi- sphere form toward inside to give the objective meta-phosphate salt glass crystallized in one direction in a relatively shorter hours.

Abstract: PURPOSE:To prevent decrease of a purification factor of a ternary catalyzer, by deciding output from an O2 sensor on the basis of detection in a range of high load and revolution, outputting a signal and arranging a control gain of the signal lower than normal. CONSTITUTION:A signal from an O2 sensor 1 is decided by a decision circuit 3  in a control unit 2, and a control gain of fuel quantity is decided in a proportional integration signal generator circuit 4, converted into driving on-duty  output of a fuel feed driving valve in an output circuit 5 and applied to an air- fuel ratio control unit 6 to control air-fuel ratio. At this time, a control gain  changing circuit 10, decreasing the control gain, is connected to the circuit 4,  and a prescribed high load and speed detector circuit 20, driving the circuit 10  at preset high load and revolution, is connected. In this way, even if speed of an  engine and its load exceed a prescribed value, the control gain can be controlled to a fixed value, and sufficient performance of purifying exhaust can be obtained even at high speed running operation.

The memory apparatus 2 assigns an address depending on the counted value, and reads out an optimum speed change stage in the involved storage address to be outputted to a display 1. Thus the optimum speed change stage suitable for the current driving speed of the bicycle is displayed and therefore the rider can select the suitable speed change gear position to drive comfortably.
