Title: Melting furnace of incineration ash
Inventor: OKUNO SATOSHI
IPC: B09B3/00
Filed: 1992-01-16
Abstract: PURPOSE:To prevent blocking trouble of both outlets in a slag side and an exhaust gas side of a melting furnace in which incineration ash is melted, reduced in volume, made harmless and made to resources. CONSTITUTION:Both exhaust gas and molten slag are extracted into an extraction chamber 6 provided in the side part of the lower part of a furnace. The duct 7 of exhaust gas and the discharge port of slag are opened in the extraction chamber. Further, air chambers 9a, 9b are formed in the upper part of the extraction chamber 6 and the inlet part of the duct 7 for exhaust gas by providing heat resistant porous bodies 8a, 8b in the inner parts of the casing plates 5a, 5b. Cool air is supplied into the air chambers 9a, 9b. Substance of low boiling point and fly dust contained in exhaust gas are cooled and solidified by injecting air to the upper part of the extraction chamber 6 and the inlet part of the duct 7 for exhaust gas and thereby purged. Further, since molten slag 2 is thermally insulated, it is not solidified and both outlets in the slag side and the exhaust gas side are not blocked.

Title: Foretelling method for trouble
Inventor: MIURA HARUO
IPC: G01M99/00
Filed: 1982-01-20
Abstract: PURPOSE:To level a partial and physical fluctuation through correction of unevenness of data and to prevent the occurrence of an erroneous decision due to disturbance, by computing a theoretical physical quantity at each input time by use of an approximate formala from a plurality of past physical quantities inputted at each constant time and a physical quantity at a current point of time. CONSTITUTION:When it reaches a data inputting time t1, a computing device 12 inputs a whole amplitude value of a shaft vibration of a rotor 2 of a fluid machine 1 to an input circuit 6(S1). The inputted whole amplitude value is stored in a memory circuit 8(S2). A theoretical whole amplitude N1 at a current point of time (t1 time) is computed by a computing circuit 7 by a minimum involution (S3) to store it in a memory circuit (S4). A whole amplitude change rate B at a current point of time is then computed (S5). It is then referred whether the whole amplitude change rate at a current point of time is positive or not (S6), and in case it is positive, a required time T, during which it attains an allowable amplitude value AL, is computed from the allowable whole amplitude value AL, the whole amplitude change rate B, and the theoretical whole amplitude value N1(S7). The required time T is compared with an allowable required time T* previously stored in the memory circuit 8(S8), and if the required time T is longer than the T*, it is foretold that the whole amplitude value exceeds the allowable whole amplitude value AL after the T* has elapsed(S9).

Title: Output circuit
Inventor: SHIMIZU SHOICHI
IPC: H03K19/086
Filed: 1987-01-16
Abstract: PURPOSE:To obtain an output circuit whose output level is matched accurately to an ECL (Emitter Coupled Logic) level by using a sensor block so as to sense the dispersion of the characteristic of transistors (TRs) and varying a gate potential so as to absorb the variance of TRs. CONSTITUTION:A TR 10 is a TR of the same kind of an output TR 3 and the variance in the characteristic of FET has a large correlation because the FET is arranged near the pattern. Thus, if the FET threshold value of the TR 3 varies, the current capability of the FET is increased and its output voltage is going to rise, then the current capability of the TR 10 is increased. Since the current flowing to a resistor 9 is increased, the gate potential results in falling down thereby compensating the rise in the output voltage finally.

Abstract: PURPOSE:To suppress the occurrence of a hazzard even if the timing of a control signal is shifted and to reduce power consumption by latching signals which are sequentially read from a transfer gate by means of a control signal by first and second invertors. CONSTITUTION:A multiplexer consists of the semiconductor integrated circuits of a bipolar transistor and the like, and the invertors 71 and 72 are cross- connected between an output terminal 41 and an inverse output terminal 42 so as to constitute a latch circuit. The first and second transfer gates 51-54, 61-64 or the gates 51-54 sequentially read input signals D1-D4 and the inverse of D1-D4 by the control signals S1-S2. The invertors 71 and 72 latch and output the signals. The invertors 71 and 72 operate to temporarily hold the outputs and to control the occurrence of the hazzard with respect to the timing of the control signals S1-S4. Furthermore, the gates 51-54 and 61-64 only transmit the input signals D1-D4 and the inverse of D1-D4, and power can be saved.

Filed: 1982-01-19
Abstract: PURPOSE:To reduce a storage area and interface lines for trace data by adding an error recognition flag bit and tracing the trace data. CONSTITUTION:An error detection signal set in an error register 8 is ORed by an OR circuit 9 to generate an OR signal. Then, a selecting circuit 10 selects the error signal of the register 8 in output address data from an address register 6 and also selects the error recognition flag bit from a no-error recognition flag bit. Consequently, output trace data from the selecting circuit 10 is an error signal showing that data at the point of time of the generation of the  error recognition flag bit is outputted from the error register. Thus, the trace  data from the selecting circuit 10 is traced by a tracing circuit 11 to obtain the  contents of the error and a microinstruction causing the error easily.

Abstract: PROBLEM TO BE SOLVED: To reduce the number of failures at the time of drawing lines by forming a protrusion working as a stopper for a writing instrument on the side of a ruler. SOLUTION: A protrusion 2 working as a stopper for a writing instrument is formed on the side of a ruler 1.

Also to protect a paper or the like from getting marks, it is desirable to round the end of the protrusion 2. Failures of drawing lines too long or the like in drawing or listing can be eliminated by using the above-said ruler 1. The trouble of remaking of the drawing or the like, therefore, is eliminated in the case of using a ball point pen, a felt pen, ink or the like. Also the ruler can be used without worrying about the positions of ends of lines, and the speed of drawing is uniformized and, therefore, the thickness of lines is also uniformized.
