Filed: 1986-12-12
Abstract: PURPOSE:To suppress the variation in the coke strength, by adding a bulk density improver to coal charged in a carbonization chamber of a coke oven so that the bulk density of the coal is substantially uniformed. CONSTITUTION:At least one bulk density improver (B) selected from among a surfactant, a heavy oil, a waste oil, kerosene, and coal tar (e.g., dialkyl sulfosuccinate) is added to coal (A) charged in a carbonization chamber of a coke oven so as to stepwise increase the amount of addition of component (B) or the concentration of component (B) towards the upper portion of the carbonization chamber, thereby substantially uniforming the bulk density of component (A) at the upper and lower portions of the carbonization chamber.

Filed: 1989-11-15
Abstract: PURPOSE:To form a reactive TiN film in high specific resistance without increasing the sputtering gas pressure by a method wherein an oxygen plasma in addition to a sputtering gas is fed to a sputtering chamber. CONSTITUTION:A semiconductor substrate 7 is mounted on a substrate electrode 6 and then reactive sputtering gas 3 is fed from a gas feed pipe 2 to a sputtering chamber 1. Next, plasma 11 is fed from an oxygen plasma feed pipe 10 to the chamber 1 in the pressure-controlled state using a conductance control valve 5. Later, when a power supply 9 is actuated, a Ti target 8 is sputtered to let it react to N2 in the gas 3 forming TiN particles so that oxygen may be simultaneously segregated in the TiN particle field by a oxygen plasma 11 to form a columnar crystal reactive TiN film on the substrate 7. At this time, the columnar crystal state can be changed by controlling the feed of oxygen plasma 11 so as to control the specific resistance of the reactive TiN film. Accordingly, the reactive TiN film of high specific resistance can be formed without increasing the sputtering gas pressure.

Title: Characteristic line converting circuit
Inventor: SAITO TAKAHITO
IPC: G01R15/00
Filed: 1989-11-16
Abstract: PURPOSE:To cope with many kinds of sensors by a small memory capacity by outputting a parameter beta (= yc/y where yc: compensation value for conversion, y: output value) as a function of a parameter alpha corresponding to its output value. CONSTITUTION:This circuit is provided with an approximate numerical value generating circuit 1 for receiving a sensor output (y) and outputting a value obtained by adding '1' to a parameter beta = yc/y required for compensation to a prescribed characteristic line and a multiplying circuit 2 for calculating y(beta + 1) and outputting it as a compensation output Kx. The other parameter alpha(= y/ye) is a value obtained by normalizing the output (y) by an end point ye of (y), and since a sensor output normalized in such a way is used, the parameter can be set uniformly without depending on the kind of the sensor. Accordingly, when beta is shown by a simple function of alpha, beta value to several alpha values is derived in advance (the more its number is, the higher the approximate accuracy of the function rises), and a coefficient of its function is determined in advance, it becomes unnecessary to derive and store a compensation value yc related to each of each sensor output, and a large quantity of storage capacity becomes unnecessary.
