Title: Switching device
Inventor: IKEDA YASUNARI
IPC: H03K17/00
Filed: 1987-06-19
Abstract: PURPOSE:To minimize a crosstalk component by constituting a switching device of the voltage/current converting circuit in differential connecting constitution connected to the input side of a switching circuit and a current/voltage converting circuit connected to the output side and saturating the output transistor of the voltage current converting circuit at the time of turning off. CONSTITUTION:When a switching circuit 1 is connected to an a1 side, a resistor 14 and the emitter of a transistor 17 is connected through the switching circuit 1 in parallel to the resistor 14 as the collector load of a transistor 13, and the collector current of the transistor 13 is supplied from a load lower in impedance. The resistance value of the resistor 14 is set to the comparatively large value, and therefore, the current is supplied from the emitter of the transistor 17 to here and converted to the voltage with a resistor 18. Since the resistance value of the resistor 14 is large when the circuit 1 is not connected to the a1 side, the transistor 13 goes to the saturated condition, the collector voltage goes to approximately equal to the base voltage, and the crosstalk component in the output signal is decreased.

Title: Die collet
Inventor: USUKI TOSHIO
IPC: H01L21/52
Filed: 1992-05-19
Abstract: PURPOSE:To eliminate adhesion of solder flowing from a lower surface of a chip to a collet, to prevent flow-out of solder to a front surface of the chip after scrubbing and to improve yield, quality by providing a step to become a flank region of solder by cutting out a predetermined region of each side except a corner of a bottom of the collet. CONSTITUTION:A step 13 is formed at a die collet by forming, in addition to a chip hiding size B, a flank size A in a direction of a bottom 4 of the collet 10. When the size of a chip 2 is h, a flowing amount of flowing solder 3a is h/2 and hiding of the collet 1 to the chip is h/2, a flank size A of the step 13 is set to h/5>=A>=h/4. Thus, adhesion of melted solder 3a protruding on a side of the chip 2 to the bottom of the collet 10 is prevented at the time of scribing. Accordingly, after scribing, it can be die bonded without dropping the melted solder on the chip 2 from the collet 10, thereby preventing decreases in manufacturing yield and quality.

Title: Operating method for blast furnace by mixed charge
Inventor: TAMURA SAKAE
IPC: C21B5/00
Filed: 1978-12-08
Abstract: PURPOSE:To stabilize the operation of a blast furnace and to increase the thermal efficiency of the furnace, by mixing previously the ore and the coke to be charged to the blast furnace. CONSTITUTION:By conventional raw material charging method, ore 5 and coke 7 are charged alternately in layers, so that the reducing gas generated at the tuyere 3 raises the central coke region 9 because the gas flow is interrupted by the molten zone 1 having high permeability resistance, hence the lateral distribution ratio is decreased. Charge of the ore and the coke previously mixed completely allows the reduced gas to distribute laterally, thereby stabilizing the furnace operation.

Title: Device for supporting rolling reduction of continuously cast slab
Inventor: HONJO HISASHI
IPC: B22D11/128
Filed: 1988-06-21
Abstract: PURPOSE:To substantially execute rolling reduction only to non-solidified layer in a cast slab, to reduce the rolling reduction force by half and to stabilize inner quality of the cast slab by arranging rolling reduction liner to be possible to change into contacting state or non-contacting state with the cast slab surface at contacting part of an inner and an outer bars with the cast slab positioning at both sides to width direction of the cast slab in the title device. CONSTITUTION:At the time of executing the rolling reduction of the cast slab 3, cylinder 32 in the outer bar 12 or further the inner bar 13 positioning to the whole width part of solidified layers 6 at both sides is worked in accordance with the width size of the cast slab 3. In this result, the rolling reduction liner 29 connecting with the cylinder 32 is shifted to the outer bar 12 and the inner bar 13 along dovetail grooves 30. In this case, as the reverse tapered face having inclination in the groove 30 is formed, the contacting face of the liner 29 with the cast slab is made to non-contacting state to the surface of the cast slab 3. Under this condition, at the time of executing the rolling reduction of the cast slab 3, as the rolling reduction is executed to the non-solidified layer 2 at the center of the cast slab 3 contacting with the liner 29 and is not executed to the non-contacting solidified layer 6 at both sides of the cast slab 3, the rolling reduction is executed only to the layer 2, and as the rolling reduction force needed at this time is very little, load to the equipment can be drastically reduced.

Abstract: PURPOSE: To improve the precision of measured value by deriving a correction value from the network area rate obtained from the permeabilities of two hard dot network films and by subtracting the correction value from the network area rate of the soft dot network film.  
     CONSTITUTION: The network area rates of two hard dot network films, which are obtained by contact-inverting a soft dot network film two times at least and are in the relation between negative and positive ones, are obtained from their permeabilities respectively, a half of the value obtained by subtracting 100 from the sum of these two network area rates is made the first correction value, which is subtracted from the network area rate to obtain a reference network area rate. The difference between the reference network area rate and the network area rate obtained from the permeablity of the soft dot network film is made the second correction value, which is subtracted from the network area rate obtained from the permeability of the soft dot network film to obtain the network area rate as shown by the curve II in Figure. In this way, the precision of measuring the network area rate can be improved.
