IPC: F23N1/00
Filed: 1982-04-20
Abstract: PURPOSE:To obtain an easy and positive control based on a wide-ranged adjustment of fuel supply by a method wherein the supply of kerosene fed by a constantly operating pump is performed by opening a solenoid valve due to the voltage based on the ON-time period of a pulse signal. CONSTITUTION:Kerosene is made to drop down on a distributor 22 which rotates 2,500 times per minute. Then air is blown into the kerosene so as to atomize and gasify it into mixed gas. The mixed gas is injected into a combustion chamber 14 and ignited by a ceramic heater 43 to begin combustion. The kerosene in an inside space 21 of a red-heated heating bowl 20 is gasified so actively that it burns with a blue flame. Hot air produced is supplied from a hot air supplying chamber to a flow-down type drying chamber, where grains are dried thereby. In order to diminish the blue flame, the kerosene supply rate to the distributor is decreased. In this instance, according to this invention, a certain amount of kerosene is pumped up constantly by a driven electromagnetic pump 25 and then subjected to an adjustment made by opening a solenoid valve 24 due to the voltage based on the ON-time period of the pulse signal.

Title: Digital signal processing circuit
Inventor: GOTO HIDEAKI
IPC: H03M1/10
Filed: 1990-03-16
Abstract: PURPOSE:To attain interpolation with an interpolation data of a few error without calculation of a complicated data by using a delay means so as to detect a change in an input data. CONSTITUTION:In the case of interpolating a data by oversampling, a delay means 4 retards a signal data within one sampling period Ts, a data comparison means 8 compares a data before delay with a data after delay so as to detect a change in the signal data for each sampling. As a result, when a change is positive, the data before delay is interpolated and when a change is negative, the data after delay is interpolated, a switch means 9 generates a digital signal data including the interpolation data and the signal data is brought into a floating data whose low-order bit is logical '0' by means of a high-order bit shift. When a change in a signal data is detected, a pseudo data generating means 11 generates a pseudo low-order bit in response to the change and replaced with a low-order bit of the floated signal data. Thus, an output error is small and the load of a succeeding analog interpolation filter is relieved.

Abstract: PURPOSE:To decide temp. matching characteristics quickly with good workability by supplying equal electric power to twin transistors, and detecting the difference of the voltages generated in the respective P N junction parts. CONSTITUTION:Equal emitter currents are supplied from constant current sources 3, 4 to a pair of transistors (TR)Q1, Q2 by closing interlocking switches SW1, 2, thereby equally elevating the temperatures of the base-emitter junction parts.
