Title: Smelting furnace
Inventor: NAKANO AKIO
IPC: F27B14/00
Filed: 1979-09-29
Abstract: PURPOSE: To obtain sufficient physical strength at a high temperature, to prevent contamination of molten metal and to reduce cost by using lava or ceramics for the furnace wall of a smelting furnace.  
     CONSTITUTION: In use, smelting furnace 3 is gradually heated from the room temperature by burner 10 and when the furnace wall temperature reaches the metal melting temperature, a prescribed amount of molten metal 2 is poured from molten-metal pouring pipe 9 to fill the furnace and injection unit 4 is operated to perform pouring into metal mold 5. Here, when furnace wall 3' is formed of lava, the wall maintains sufficient strength even at a high temperature owing to its high refractoriness and oxidation resistance and molten metal 2 in furnace 3 never gets contaminated. Further, its heat retaining property prevents a sudden rise drop of molten metal temperature to make pouring temperature even. When it is formed of ceramics, its high refractoriness and oxidation resistance which is more superior than lava provide sufficient strength at a high temperature and molten metal 2 in furnace 3 never gets contaminated.

IPC: F16K17/196
Filed: 1982-07-20
Abstract: PURPOSE:To eliminate a cross-over type relief valve, by a method wherein a spring bearing is slidably mounted in a pressure chamber, and when the spring bearing is separated from the wall surface of a spool by moving the spring bearing togetherwith the spool, a pore formed in the spring bearing is opened to communicate the pressure chamber with a tank. CONSTITUTION:With a direction switching valve 33 switched to the left side, pressure oil flows from a pump port 2 to an actuator 36 through an oil flow hole 35, a check valve 29, and a port 4. A part of the oil flowing in the pump port 2 also flows in a pressure chamber 7 through an orifice 27, and a spool 6 moves rightwardly against a spring 14. In which case, a spring bearing 10 in the pressure chamber 8 follows the spool, and a bent part 12 is separated from a wall surface 18, whereby a pore 20 in the spring bearing is opened, and the pressure chamber 8 is also communicated with a tank 26 togetherwith a pump port 3. Thus, resistance against the rightward movement of the spool 6 is effected only by the spring 14, and movement of the spool becomes rapid.

Abstract: PURPOSE:To reduce the power consumption of a static semiconductor memory by controlling the switching of a switch element by a failure voltage at a PN junction part and fixed voltage. CONSTITUTION:Gate electrode A of IGFETQ4 is connected to N-type impurity region 5b in P-type silicon substrate 1 and IGFETs Q1 and Q2 sharing region 5b as a common electrode are connected in series between a current source and the earth. With switch SW open, transistors Q1 and Q2 are both OFF and FETQ4 turns ON by being applied with a failure voltage more than a threshold level from a PN junction part formed of substrate 1 and region 5b. With switch SW closed, transistors Q1 and Q2 conduct to apply a reverse voltage to the PN junction and transistor Q4 turns OFF. Therefore, the switching of the swmiconductor switch is controlled by the failure voltage and an external reverse voltage decreasing the failure voltage below the threshold level, so that the power consumption of a static memory using the semiconductor switch can be reduced.

Abstract: PURPOSE:To establish initial synchronization and re-synchronization by controlling the switching of a gate inputting a restoration signal outputted from a reception signal based on the result of decision whether the state is in synchronizing state or abnormal synchronizing state and the result of detection of a blank detecting circuit. CONSTITUTION:A microcomputer 15 receives a pulse (s) from a synchronous detecting circuit 11 and outputs a latch pulse (l) to an S/P conversion circuit 14. A check means 15a checks whether the pulse (l) is information E for detecting the abnormality or not and when the pulse is not the information E, an error pulse (d) is generated. A decision means 15c discriminates whether or not the state is in the synchronizing state based on the result by counting the pulse (d) by a counter means 15b and when abnormal synchronous state is discriminated, an abnormal synchronous signal (e) is brought to H level for a prescribed time. A control means 15d inputs the signal (e) and an output Q of a D.F/F13a to generate a clear pulse (p) and a control signal (c). A trigger generating means 15e uses the signal (e) to control the generation of a trigger pulse (t). A gate 12 closes the gate when the signal (c) is at L level and opens the gate at H level.
