Inventor: FUKUWAKI KATSUMI
IPC: G06F11/34
Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To securely record important data according to priority and a data holding time while suppressing the futile use of a free area, and to improve recording efficiency. SOLUTION: This method has priority set in a priority setting process by storage request sources of data. Then data holding times are set in a holding time setting process by the priority set in the priority setting process, and when new data is stored, a 1st data storing process stores the whole or part of corresponding data in a free area of the storage medium according to the priority set in the priority setting process on condition that the free area is large enough. When the free area of the storage medium is short, an area securing process deletes data which has its priority set low in the priority setting process and whose data holding time is elapsed from the storage medium to secure a free area, and a 2nd data storing process stores the data in the free area.

Inventor: HAMADA HISAO
IPC: C21B13/00
Filed: 1982-11-01
Abstract: PURPOSE:To perform an operation which is stable for a long period of time without decreasing reduction rate in the stage of reducing preliminarily powder and granular ore with the high temp. waste gas generated from a melt reduction furnace as reducing gas by using gaseous hydrocarbon of a low temp. together as fluidizing gas and a reducing agent. CONSTITUTION:A part of gas contg. hydrocarbon such as CH3, C3H8 or the like is introduced 13, 13' respectively into a conduit 12 for the above-described high temp. reducing gas or near a supply port 8 for the reducing gas in a preliminary reduction furnace 1. On the other hand, a position of the gas contg. hydro-carbons corresponding to the amt. to remain after subtracting the amt. necessary for the preliminery reduction of Cr2O3 from total gas is supplied directly 9 to the fluidized bed 2 region of the furnace 1, and the operation of the furnace 1 is performed. The temp. of the reducing gas of a high temp. can be decreased effectively by increasing the flow rate of the gas contg. hydrocarbon to be supplied 12. However, in the case of reducing preliminarily hardly reducing Cr2O3, the rate of partial thermal crackng of hydrocarbon increases and there is possibilitythat the amt. effective for reducing Cr2O3 decreases. Therefore, it is possible to compensate some part (corresponding to the remaining part) with the amt. of the gas contg. hydrocarbon to be supplied directly into the bed 2.

Filed: 1983-10-14
Abstract: PURPOSE:To produce a widely increased amount of ions by installing a hot cathode, an electron diaphragm electrode and a thermion-leading-out electrode around a cylindrical anode in a hot-cathode electron impact type ion source for a tetrode analyzer. CONSTITUTION:An electron diaphragm electrode 2 is installed around a cylindrical cage-like anode 1 which has an electron permeable grid-like or mesh-like circumferential surface. After that, a mesh-like thermion-leading-out electrode 3 of 10-20 mesh is installed outside the electron diaphragm electrode 2 and an annular hot cathode 4 is installed outside the mesh-like thermion-leading-out electrode 3, thereby constituting a hot-cathode electron impact type ion source for a tetrode analyzer. Owing to the above constitution, the effect of the mesh-like lead-out electrode 3 reduces the influence of space charges while causing an increased amount of thermions to be discharged thereby introducing a great amount of electrons into the cylindrical cage-like anode 1. Consequently, it is possible to widely increase the amount of ions produced.

IPC: H01L21/265
Filed: 1984-09-14
Abstract: PURPOSE:To eliminate the problem of crystal defects produced by the difference in atom radius between the atom of a semiconductor element at the time of ion implantation, by heating in a steam atmosphere at a temperature within a restricted range, and then heating in a nitrogen atmosphere at a temperature within a restricted range for a specific time or more. CONSTITUTION:For removal of crystal defects after ion implantation, as annealing, the semiconductor substrate is heated in a steam atmosphere at a temperature of 800-1,000 deg.C and then heated in a nitrogen atmosphere at a temperature of 600-1,000 deg.C for 30min or more: that is, defects 13 are generat ed when P-ions 12 are implanted to a base layer 3. Succeeding forced diffusion forms an N-emitter layer, and steam oxidation during temperature fall makes the crystal defects 13 to be absorbed to the surface oxide film 14, but part of defects and laminated defects OSF produced by oxidation come to remain as remaining defects 15. These defects 15 are removed by annealing in a nitro gen atmosphere for 30min or more. This manner reduces the leakage current of the junction between the base layer 6 and the emitter layer 7. Of course, defects or remaining defects produced in a collector contact layer 8 at the time of ion implantation are similarly removed.

Title: Active sound eliminating device
Inventor: OKUBO MINORU
IPC: F01N1/00
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To eliminate an exhaust sound which has a peak of sound pressure level in the primary to tertiary frequency sounds by interposing a resonance type sound elimination pipe on the upstream side of a sound adjusting pipe. SOLUTION: Exhaust after passing through a main pipe 1 passes through a resonance muffler pipe 5, a primary sound adjusting pipe 6, and a secondary sound adjusting pipe 7 together with noise and interferes with a sound from a branch pipe at the main/branch confluence part 2a of a branch pipe 2 to attenuate the noise, and is discharged from the terminal opening part of an exit pipe 3. A speaker unit SU controls the loudness of a sound for sound elimination generated by its internal speaker. A resonance chamber in a resonance type muffler pipe 5 provided annularly on the upstream side of the sound adjusting pipe 6 is so constituted that a second harmonic frequency (f2 =f1 ×2) sound included in the noise resonates. The primary and secondary pipes 6 and 7 are formed of sound absorbers such as glass wool and. absorb high-frequency sounds.  Thus, the sound reaching the main/branch confluence part 2a of the branch pipe 2 has its higher harmonic sounds and second harmonic frequency sound attenuated and the noise of the remaining primary and third harmonic frequency sounds is attenuated with the low-frequency sound from the speaker unit SU.
