Title: Thermal transfer head and printer
Inventor: TANAHASHI MAKOTO
IPC: B41J2/36
Filed: 1995-12-11
Abstract: PROBLEM TO BE SOLVED: To eliminate a blurred condition at a part having a small gradation level and discontinuity in a transferring density in the case where the gradation is represented by changing an area of a dot. SOLUTION: A thermal head is comprised of individual electrodes 2, a common electrode 1 and heating resistors 3. Electric currents I1 , I2 based on printing signals are allowed to flow in each of individual electrodes 2, e.g., individual electrode 2A by passing through two or more current passages, e.g., passing through heating resisters 3A, 3B. The lengths L1, L2 of the heating resisters 3A, 3B in the two or more current passages are different from each other so that the resistance values Ra, Rb are different from each other. As a result, energy is concentrated in the resister 3B, then a heat quantity of the resister 3B is greater than the other. Thereby, it is possible to eliminate a blurred condition at a part having a small gradation level and discontinuity in a transferring density.

Title: Cadmium oxide powder for nickel cadmium storage battery
Inventor: KAGAWA KEIICHI
IPC: H01M10/30
Filed: 1997-12-16
Abstract: PROBLEM TO BE SOLVED: To significantly improve the lifetime of a storage battery by evenly distributing the magnesium oxide powder in the cadmium oxide powder as a negative electrode active material, in a condition such that a part thereof exists as a compound oxide. SOLUTION: Magnesium oxide powder as magnesium is distributed uniformly in the cadmium oxide powder at 30 wt.% or less, preferably at 0.01-30% in the condition that a part thereof exists as a compound oxide. This cadmium oxide powder is used as a negative electrode active material for nickel cadmium storage battery. As a manufacturing method, cadmium ground metal is first melted and volatilized in a volatilizing furnace. The cadmium steam obtained thereby is led into an oxidization chamber. At the same time, melted magnesium is volatilized, and the magnesium steam is led into the oxidization chamber. The cadmium steam and the magnesium steam are blown out in the oxidization chamber in the horizontal direction to have it reacted the oxidizing gas such as air, and magnesium contained cadmium oxide is thereby obtained.  This magnesium contained cadmium oxide is recovered by a back filter for obtaining cadmium oxide powder.

Abstract: PROBLEM TO BE SOLVED: To provide a method performing the coding of an ECC(error-correcting code) block efficiently in order to enhance a write performance to a storage device in which an ECC block having liner codes like a Reed-Solomon code is adopted. SOLUTION: At the time of calculating an ECC block F2 having a PO part q2 posterior to an updating by updating the data f1 of the data sector of one parts being in plural data sectors constituting an ECC block F1 having the PO part q1 generated with linear codes like the Reed-Solomon code with data f2 , and exclusive OR f1 +f2 between data f1 to be updated and updated f2 is calculated by operating ECC blocks F1 +F2 being an exclusive OR between source data parts the ECC block F1 prior to the updating and the ECC block F2 posterior to the updating. Exclusive ORs among data sectors which are not updated become zero. Next, when codings are performed as to the ECC blocks F1 +F2 being the exclusive OR, an OP part having the form of an exclusive OR q1 +q2 is obtained by the linear property of the Reed-Solomon code. Then, q2 can be calculated by the exclusive OR between q1 +q2 and q1 .
