Title: Control device for desiliconizing molten iron
Inventor: KONDO MIKIO
IPC: C21C1/04
Filed: 1985-06-03
Abstract: PURPOSE:To make the content of silicon in a molten iron after a desiliconization treatment coincident with a target value by measuring continuously the content of silicon before and after the desiliconization, tapping speed and amt. of the desiliconizing agent to be added of the molten iron, comparing the measured values after making prescribed calculations with the set values and controlling the amt. of the desiliconizing agent to be added. CONSTITUTION:The content of the silicon before and after the desiliconization is measured by instruments 22, 23 and the tapping speed is measured by an instrument 24. The measured values are inputted to the respective arithmetic logics 26, 27, 28 of an electronic computer. An arithmetic logic 29 calculates the maximum likelihood estimator of the desiliconization reaction constant from the input values from the logics 26, 27, 28 and the set value of an external setter 20. The command value for the amt. of the desiliconizing agent to be added is then calculated in an arithmetic logic 30 and the command value is inputted as the output from the electronic computer 14 to a control device 31 for the amt. of the desiliconizing agent to be added. The deviation between the command value and the actual value calculated in an arithmetic unit 33 for the amt. of the desiliconizing agent to be added from the output of hopper load cells 19, 19a is determined by the device 31 and the rotating speeds of rotary valves 11, 11a are changed by a control device 32 for the rotating speeds of the rotary valves, by which the amt. of the desiliconizing agent to be added is controlled.

Title: Semiconductor device
Inventor: YONEDA YOSHITADA
IPC: H01L23/36
Filed: 1994-05-31
Abstract: PURPOSE:To more efficiently cool a semiconductor substrate. CONSTITUTION:A heat conducting body 21 is composed of such a metal as copper, and conducts the heat from an upper metallic body 5 to a heat sink 13. Therefore, the heat loss conducted to a metallic electrode 3 which is in contact with a semiconductor substrate is nearly evenly dispersed to both the upper metallic body 5 and a lower metallic body 6 without bias, because the heat loss is conducted to the heat sink 13 not only from the lower metallic body 6, but also from the upper metallic body 5. Consequently, the cooling efficiency of the semiconductor substrate is remarkably improved and, at the same time, the temperature distribution in the direction along the main surface of the semiconductor substrate is uniformized. Accordingly, a small-sized semiconductor element which can handle a large current and have excellent characteristics can be obtained.

Filed: 1988-05-18
Abstract: PURPOSE:To prevent the pulse and the oscillation that cause a fault having the small width and to ensure the safe and sure working even with a digital circuit using two asynchronous clocks by switching these clocks via a smallest circuit and in the minimum time with no influence given to the output. CONSTITUTION:When the clock selecting signal changes its clock to a 2nd clock from a 1st clock, the means 1 and 2 produce the differential pulses from the selecting signal and the output clock. While a means 9 inhibits a flip-flop 3 which permits the output of the 1st clock by means of logic '1' of the differential pulse and the fall of the 1st clock and permits a flip-flop 4 that inhibited the output of the 2nd clock by means of the inhibiting signal of the flip-flop 3 and the fall of the 2nd clock. In such a constitution, the asynchronous clocks can be switched in the minimum time and with a circuit of the smallest structure with no influence given to the output.

Title: Method of controlling stop position of mover
Inventor: KOJIMA EIJI
IPC: G05D3/12
Filed: 1984-06-11
Abstract: PURPOSE:To prevent hunting of a mover in the vicinity of a stop position by rotating a driving motor for the mover in normal and reverse directions in such a manner that the driving time is gradually shortened in order to make the mover be stationary within the stop permissible range. CONSTITUTION:When a mover is moved by a driving motor to reach the stop permissible range L, after the lapse of a fixed time T0 from the point of time the mover reaches the range, the driving motor is stopped. If the mover overruns the stop permissible range L at this time, the driving motor is reversed to move the mover for a fixed time T1. The moving time T1 at this time is shorter than the time T0, and subsequently, the driving motor is repeatedly rotated in the mormal and reverse directions in such a manner that the driving time is gradually shortened until the stopped mover is positioned within the stop permissible range L.

Title: Wind wiper
Inventor: TERAURA MINORU
IPC: B60S1/44
Filed: 1982-07-09
Abstract: PURPOSE:To automatically absorb expansion of a cable, by combining a pulley engaged with a driven shaft with a pulley pivotably supported to the drive shaft to form a drive pulley of a wiper, and meshing teeth formed on both the pulleys with each other with the aid of an elastic member. CONSTITUTION:When a first pulley 11 engaged with a drive shaft 16 is rotated in the direction as depicted by E, ratchet teeth 12 formed on the first pulley 11 is idly meshed with ratchet teeth 15 formed on a second pulley 14 in the direction of E, while the second pulley 14 being also rotated in the direction of E through a loop cable 2. Under such a circumstance, if the cable is not stretched, both the pulleys 11 and 14 are simultaneously rotated in the direction of E without idle rotation. When the cable is stretched, rotation of the second pulley 14 is not generated simultaneously with the rotation of the first pulley 11 in the direction of E because of the expansion of the cable 2. When the first pulley 11 only is rotated by the idle rotation of the ratchet teeth 12, and thereby to wind up the cable 2 to absorb the expansion, tensile force is acted on the cable 2 to rotate the second pulley 14 too in the direction of E.
