Title: Curve control device for endoscope
Inventor: SUZUTA TOSHIHIKO
IPC: G02B23/24
Filed: 1988-04-26
Abstract: PURPOSE:To prevent breakage of a treating tool and to enable execution of safe and reliable observation and medical treatment, by a method wherein an angle stopper is disposed to a control part body so that it is displaced to a position where a curved control member is constrained and a position where its movement is allowed. CONSTITUTION:In an insertion-in-cavity-body part 3, a flexible tube part 5, a curving tube part 6, and a tip constitution part 7 are connected to each other. An angle stopper 11 to regulate movement of an angle lever 8 for controlling the curve of a curving tube part 6 is formed by, for example, a rigid beltform plate. The tip thereof is branched into two nipping pieces 13a and 13b to form a U-shape, and the base part thereof is curved along, for example, the spherical shape of a control part body 2. When there is a need to regulate the curve of the curving tube part 6, the free end of part of the angle stopper 11 is rotated to a position right below. The angle lever 8 is positioned between the nipping pieces 13a and 13b. When control of the curve of the angle lever 8 is effected freely, the angle stopper 11 is rotated to a position 11A. This rotation results in release of the angle lever 8 from regulation.

Title: Method for transfer pouring from refining furnace
Inventor: YOSHIDA MASAHIRO
IPC: C21C7/00
Filed: 1984-05-23
Abstract: PURPOSE:To produce stably a metal which lessens gas absorption by decreasing the amt. of nitrogen and oxygen to be absorbed as far as possible in the transfer pouring stage of the molten metal from a refining furnace. CONSTITUTION:A ladle 3 is moved upward by using a ladle lifter 5 to decrease the surface area of tap flow 9 and to decrease falling distance at the start of tapping from a converter in the transfer pouring stage of the molten metal from the refining furnace 1 into a ladle 3. The level of the molten steel 10 in the ladle 3 rises and the intrusion of air in the tap flow 9 increases and therefore a carriage 2 is moved to the position where the tap flow 9 strikes against a dash board 6 in the middle period of tapping. The depth of the plate 1 from the surface of the molten metal in the molten metal 10 in the ladle 3 is adjusted by a lifting cylinder 8 in such a way that the splashes of the molten metal as a result of the collision of the molten metal flow 9 against the board 6 is obviated.

Title: Semiconductor logic circuit
Inventor: NAKASE YASUNOBU
IPC: H01L21/8249
Filed: 1992-04-23
Abstract: PURPOSE:To obtain a logic circuit realized with less number of components in which the dependency of a gate delay time on an input number is less. CONSTITUTION:Bipolar transistors(TRs) 5-8 are employed for rising of a potential at an output terminal. Thus, the deterioration in the speed at the rising due to the increase in the parasitic capacitance of the output terminal 1E is less. Moreover, since the falling down of the potential at the output terminal is executed by using a current source 9, it is not required to build up a logic circuit to extract a current from the output terminal 1E at the falling-down different from a conventional circuit. Thus, the logic circuit is realized with less number of components. The deterioration in the speed at the falling down of the potential at the output terminal 1E caused by the increase in the parasitic capacitance is prevented by increasing a current from the current source 9.

Title: Memory device whose low-order side address is decoded
Inventor: SAKAGUCHI TSUYOSHI
IPC: G11C8/00
Filed: 1986-05-07
Abstract: PURPOSE:To reduce the generation of heat, by averaging the number of times of accesses per unit time of each memory block. CONSTITUTION:When a CPU performs a memory access sequentially, each memory block is accessed sequentially as the first memory block 9, the second memory block 10,..., the n-th memory block 11, the first memory block 9,.... Therefore, the memory access from the CPU, etc., is not concentrated on a specific memory, and it is averaged. For example, as for the memory block 9, it has a time of (N-1)-fold of the memory access time from the CPU, etc., between access. In this way, since the generation of the heat is also averaged, a temperature rise in each memory block is suppressed, and reliability for the device can be improved.
