Title: Apparatus for deashing coal
Inventor: YOSHIKAWA HIROBUMI
IPC: C10L1/32
Filed: 1983-08-08
Abstract: PURPOSE:To attain a high carbonaceous component recovery ratio and a high deashing ratio, by partitioning the inside of a tower into a plurality of zones and separating a carbonaceous component and ash by a flotation method. CONSTITUTION:A coal/water slurry is fed through a pipe line 1 to a flotator 3 having perforated plates. A collector and a gas are fed through pipe lines 6 and 7 to a heater 8. The collector is vaporized and fed together with the gas through a pipe line 9 and an air diffuser plate 9A to the flotator 3. Carbon particles are deposited on bubbles contg. the collector ascending within the flotator and ascend together with the bubbles within the flotator. The carbon particles concentrated at the top thereof are drawn out through a pipe line 4 to the outside. The residual coal having a high ash content remaining within the flotator is discharged through an outlet 5 at the lower part thereof. Owing to the presence of the perforated plates, a descending stream contg. the carbonaceous component is circulated through each chamber partitioned by the perforated plates and the flow-out of the carbonaceous component through the ash discharging port 5 is inhibited. Further, since separation stages are increased, the degree of separation of the carbonaceous component and ash can be improved.

Title: Motor positioning control system
Inventor: TAKAMUKAI HIDEYUKI
IPC: G05D3/12
Filed: 1990-06-01
Abstract: PURPOSE:To make a driven shaft follow a driving shaft at real time by counting the number of output pulses of an encoder produced in proportion to the rotational frequency of the driving shaft and applying the table value read out of a cam curved line storage part to a position control part for driving motor of the driven shaft as the command value. CONSTITUTION:An encoder 13 produces the number of encoding pulses proportional to the rotational frequency of a motor, and these encoding pulses are counted by a counter 14. A pulse output circuit 17 outputs the position command value calculated by a CPU 10 based on the data on the absolute revolving position of a main axis obtained by the counter 14 as well as the rotational frequency of the driven shaft obtained by a data setter 15 in a single block action in the form of the arranged the number of position command pulses proportional to the command value obtained in a fixed time. Thus the data used for scan of a cam curved line table is calculated based on the number of encoding pulses. As a result, the driven shaft can follow up the driving shaft and a synchronizing function similar to a machine cam system is obtained.

Title: Ink jet recording device
Inventor: FUJII MASAHIKO
IPC: B41J2/205
Filed: 1990-06-01
Abstract: PURPOSE:To form a high-quality image which is almost free from any missing part or ink stain by providing a temperature control device which controls the temperature of a printing head and a temperature setting device which sets the controlled temperature of the temperature control device. CONSTITUTION:Ink 10 is supplied one-way to an ink path 9 from an ink supply orifice 2 and a voltage from an electrode pulse is applied to a heater 7 installed in the path. Ink droplets 8 are ejected from a nozzle 6 by the pressure of a valve for vapor generated by heating of a heater and thereby reach a recording medium for data recording. A temperature detection part 11 and a heat generation part 12 are provided near an ink path in a printing head 1. A control part 14 sends a signal to the heat generation part by a signal from the temperature detection part 11 so that the temperature of the printing head 1 reaches a controlled temperature at which the printing head 1 is set. A controlled temperature switching signal 15 is entered in the control part 14 from a printing control part or a temperature setting part 16 such as a control panel of a printing device to set a controlled temperature. An optimal droplet amount is discharged in a simple manner to a recording medium which indicates a varying dot spread. Thus a high-quality image free from missing dots or ink stain is obtained.

A correction value C = 1.5/100 mm is previously read out and inputted to a ROM 20, an EEPROM 19, or the like. A predetermined operation is conducted in a central processing unit 17. Pulse signals of the predetermined number in accordance with a change-over operation of the speed change-over switch 39 and a rotation direction command signal are inputted to the gap adjusting drive circuit 38. A stepping motor 9 is rotatively drive forward or reverse by a rotating angle corresponding to the predetermined step number.

Title: Heat treatment method for thin-film
Inventor: OKUMURA KATSUYA
IPC: H01L21/3205
Filed: 1982-08-20
Abstract: PURPOSE:To prevent a breaking at a step of the thin-film without changing a P-N junction by partially heating and melting a glass film linearly, moving the melting region while being crossed at right angles with the region and smoothing the glass film in the manufacture of a semiconductor device, which is integrated to a high degree and consists of the thin-film. CONSTITUTION:A substrate 11 is placed near by a heater 16, the temperature of the heater 16 is adjusted so that the surface of the substrate 11, a glass layer 15, melts, and the substrate 11 is moved in the direction rectangular to the heater 16 at speed such as the speed of 10mm./min. The section (a) of the glass layer 15 just under the heater 16 melts through such a method. Accordingly, the melting region (a) moves to the right by shifting the substrate 11, and the glass film 15 at a stepped difference section takes a smooth shape to prevent a breaking at a step. The depth of the junction of the semiconductor device does not change because a time when the glass layer is exposed at a high temperature is short.

Abstract: PURPOSE:To form continuously a plating film having excellent wettability and adhesion to a steel strip, particularly high tensile steel strip, by heating a sheet strip having a prescribed thickness in a direct fire heating furnace respectively at the specified temp. of the steel strip, the heating rate of the steel strip, and the excess air rate during durning of an injected combustion gas then subjecting to hot-dipping in succession. CONSTITUTION:A steel strip 1 which is conducted into a direct fire heating furance 6 is fed through a preheating zone 6A to a heating zone 6B, whereboth surfaces of the strip 1 are quikly heated by the high-temp. combustion gas injected 8 from horizontal burners 7 and the radiation heat from the inside wall of the furnace 6. The heating of the strip 1 in this stage is accomplished under the conditions; 400 deg.C-(-23.3t+805) deg.C (t; thickness) heatint temp. for the steel strip, >=35/t deg.C/sec heating rate for the steel strip, and 0.7-1.0 excess air rate during combustion of the injected gas 8 or combustion. The heated strip 1 is then conducted to a plating bath 5 and is subjected continuously to hot-dipping. As a result, the formation of hardly reducible films on the surface of the steel strip during heating is obviated, and it is possile to apply the hot-dipping on the high tensile steel strip which is heretofore considered as a hardly platable kind of steel uner the reduction conditions equal to the conditions for an ordinary kind of steel strips or below.
