Title: Semiconductor memory
Inventor: NAKANO TAKESHI
IPC: G11C11/417
Filed: 1981-12-08
Abstract: PURPOSE:To substantially uniformly form the resistance value of data wirings between a data input and output circuit and all memory cells by forming contacting resistance parts in the course between the data input and output unit at the memory cell side of the input and output circuit and the data input and output units of the nearest memory cell. CONSTITUTION:Direct wiring between a data input and output unit 2 and the nearest memory cell 11 is eliminated, a contact unit is formed instead between the data wirings 3 and the memory cell 11, and is constructed in the wiring structure similar to the other memory cells 12-14. In this manner, the values of the contacting resistances between the unit 2 and all memory cells are equalized, thereby suppressing the irregularity in the writing and reading times of the data among the memory cells 11-14.

Title: Blowing lance for refining of molten metal
Inventor: TAKAHASHI HIROSHI
IPC: C21C5/46
Filed: 1983-10-21
Abstract: PURPOSE:To prevent cracking and stripping of a coating refractory layer owing to oscillation during use of a blowing lance for refining of molten coated with refractories and to extend the service life of the lance by attaching a lumped material consisting of refractories having specific compsn. to the top end of said lance. CONSTITUTION:A coating layer 2 consisting of refractories is formed on the surface of a steel pipe lance 1 to be used in the stage of performing preliminary refining such as desiliconization, dephosphorization, desulfurization or the like of molten iron by blowing powder of carbide, lime, etc. into molten iron to prevent melting of the steel pipe lance by the molten metal and the consequent decrease in the service life thereof. The refractory cooling layer is cracked and stripped by the oscillation in the moltem metal in this case and the coating layer is eroded in short time. a lumped material 3 consisting of Al2O3-SiC-C or MgO-C refractories is attached to the top end of the lance 1 or the part slightly apart from the top end in order to prevent such erosion. The oscillation in the molten iron is thus absorbed and the cracking and stripping of the layer 2 are prevented, by which the decrease in the service life owing to the erosion of the lance is prevented.

Title: Optical transmitter
Inventor: INOUE YASUSHI
IPC: H04B10/60
Filed: 1999-07-12
Abstract: PROBLEM TO BE SOLVED: To enable an optical transmitter to transmit signal light at a higher speed while the transmitter uses a current-modulated LED light source. SOLUTION: The modulation bandwidth of an optical transmitter is widened by using a semiconductor optical amplifier 12 in the succeeding stage of an LED 10. For that purpose, the amplifier 12 is operated in a gain saturation area. The degree of the gain saturation of the amplifier 12 varies depending upon the power of the input light to the amplifier 12 and the structure, driving condition, etc., of the amplifier 12. When, for example, (1) the power of the output light of the LED 10 is high, (2) the element length of the amplifier 12 is long, and (3) a high-bias current is injected into the amplifier 12, the gain of the amplifier is apt to saturate. Therefore, the amplifier 12 can be operated in a gain-saturated state by setting theses parameters.

Abstract: PURPOSE:To improve the resolution and dry etching resistance by applying a negative resist made of an arom. vinyl compd. polymer to a substrate, irradiating the resist with far ultraviolet rays, X-rays or charged corpuscular beams and exposing an upper resist layer with light. CONSTITUTION:A negative resist made of an arom. vinyl compd. polymer is applied to a substrate and made insoluble by irradiation with far ultraviolet rays, charged corpuscular beams or X-rays.
