(b) One or more kinds of the fluorides and chlorides of the group of the alkali metals and the alkaline earth metals are added at to 1 to 30wt.% in total. (c) One or more kinds of the group of the metals and alloys having high affinity to oxygen are added at 1 to 20wt.% in total. The desulfurizing and denitriding agent powder contg. these components and having 10 to 200mum grain sizes is sprayed from a top blowing lance to the surface of the molten steel by a carrier gas in a 0.1 to 1kg/min.ton range. As a result, the sufficient infiltration of the refining agent powders of the desulfurizing agents, denitriding agents, etc., into the molten steel is possible.

Title: Semiconductor memory device
Inventor: MIYAKE JUN
IPC: G09G5/36
Filed: 1991-04-12
Abstract: PURPOSE:To provide the semiconductor memory device enabling serial access in an arbitrary data size with simple configuration. CONSTITUTION:This device is provided with a jump function to perform random access to the arbitrary address of a two-dimensional address space at least and to perform serial access from the address, and a line reset function to perform access from the arbitrary address of the line serially accessed by the above-mentioned function to the leading address of the next line and to perform serial access from the address. While combining the above-mentioned two functions of the jump function and the line reset function, a fixed rectangular area is scanned. Since address control for segmenting the arbitrary data size can be fetched into a chip, the number of external equipments can be reduced at a system to integrate the chip, and control is simplified.

Title: Energy absorbing member
Inventor: TSUCHIHARA HAJIME
IPC: F16F7/12
Filed: 1999-04-15
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost and to set desired energy absorption performance by connecting adjacent bottomed tube bodies with positions of bottom wall sections inversely arranged in turn. SOLUTION: Many small chambers 5 are connected with positions of bottom wall sections 3 inversely arranged to form an energy absorbing member 1. An upper die and a lower die can be made a simple upper/lower split match structure for injection molding. Peripheral wall sections partitioning between adjacent small chambers 5 can be set to a nearly constant thickness while setting the draft freely as compared with injection molding with a conventional resin honeycomb rib structure. Since the draft can be increased, no special machining is required in manufacturing molding dies, and moldability is improved. The thickness of the peripheral wall sections 2 can be kept nearly constant even when the draft is increased, and the desired energy absorption performance can be set.

Abstract: PURPOSE:To prevent a fact that the influence of the wiring resistance of a wiring and the physical characteristic of a semiconductor substrate, etc., appears in a specific bit by dispersing and arranging a constant-current source block in plural units for executing a parallel operation in accordance with the same bit. CONSTITUTION:The output of an input buffer block 2 in which the data D1 of the uppermost bit is stored is connected to each unit constant-current source block of first, third, fifth and seventh from the left side, the output of an input buffer block 2 in which the data D2 of a second bit is stored is connected to each unit constant-current source block of second and sixth from the left side, and the output of an input buffer block 2 in which the data D3 of a third bit is stored is connected to a fourth unit constant-current source block from the left side. That is, since the unit constant-current source block is dispersed and arranged in the area in which the constant-current source block is placed, the influence of a wiring resistance of a wiring and the physical characteristic of a semiconductor substrate, etc., is also dispersed. In such a manner, it can be prevented that its influence appears strongly in a specific bit.
