Title: Production of extra-low chloride titanium powder
Inventor: TAMURA MICHIO
IPC: B22F1/00
Filed: 1992-07-21
Abstract: PURPOSE:To carry out the production of the extra-low chlorine titanium powder at a low cost by pulverizing and removing the brittle layer on the surface layer part of a smelted titanium lump subjected to a hydrogen absorption treatment, heating and holding the remaining lump under specific conditions and rapidly cooling the lump, thereby removing the oxide layer of the surface layer. CONSTITUTION:The brittle layer of the surface layer part of the smelted titanium lump heated and held in a hydrogen-contg. atmosphere is removed by a mechanical pulverization method. The remaining lump is then heated and held for the time of >=5 minutes and <=3 hours to and at a beta single phase temp. region or beta+delta= phase temp. region. This lump is cooled at a cooling rate below air cooling rate. The lump is thereby transformed to the martensite phase alpha of the rhombic crystal of the beta phase and to the alpha'' single phase structure without contg. the soft alpha phase or the alpha''+beta= phase structure, by which the alpha phase prohibiting the pulverization to powder is dissipated and the phase having the poor ductility is formed. The oxide layer formed in the surface layer part at the time of the heating and holding and the cooling is removed and thereafter, the lump is subjected to mechanical pulverization. The entire part of the lump consists of only the brittle phase in the preceeding stage and, therefore, the powder is effectively obtd. by the mechanical pulverization. The titanium powder is obtd. by subjecting the powder further to dehydrogenation annealing in a vacuum atmosphere.

Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To obtain a liquid crystal, element with which display unevenness, etc., may be effectively prevented with lower electric power consumption and which is improved in display characteristics by setting the width of the counter electrodes in the intersecting parts of the lead electrodes on a first substrate and the counter electrodes on a second substrate shorter than the width of pixel electrodes. SOLUTION: The width of the counter electrodes 104 in the intersected parts of the lead electrodes 101 on the first substrate and the counter electrodes 104 on the second substrate is made shorter than the width of the pixel electrodes 103. Namely, the width of the counter electrodes 104 in the interelectrode intersected parts is made shorter in order to decrease the parts where the lead electrodes 101 and the counter electrodes 104 intersect are decreased. Intersecting capacity components are eventually decreased. The electrostatic capacity in the intersected parts of the lead electrodes 101 and the counter electrodes 104 decreases and, therefore, the electric power composition in driving the liquid crystal element may be reduced.  A low-resistance wiring material is used for the counter electrode 104 parts in the intersected parts, by which the resistance value of the counter electrodes 104 is lowered and the display unevenness, etc., are effectively prevented.

Title: Atomic beam detector
Inventor: KARIYA NORIJI
IPC: H01S1/00
Filed: 1985-09-03
Abstract: PURPOSE:To prevent the deterioration in S/N characteristics, by making the width of ionizer of an atomic beam detector widest at its center part where the temperature most easily rise making the width narrower at the nearer parts to both ends where the temperature is not easy to rise, and making the resistivity change locally. CONSTITUTION:The width of an ionizer 31 in the form of a ribbon is made widest at the center part where the temperature most easily rise, and made narrower at the near parts to both ends where the temperature is not easy to rise because of thermal diffusion to the both sides of connection terminals 32a and 32b. In such a structure, a resistivity changes locally. Consequently, a heat generation at the time of heating increases in accordance with approach to the both ends, so that the lack of uniformity of heating temperature distribution due to thermal diffusion is compensated. This makes it possible to make the heating temperature distribution of the ionizer 31 uniform, and the heating temperature of the ionizer 31 can be suitably set to a specified value. The temperature distribution of the ionizer 31 is made uniform, the deposition or revaporization of Cs atom is prevented, the deterioration of S/N characteristics is dissolved, and accuracy and stability of resonance frequency are improved.

Filed: 1981-12-07
Abstract: PURPOSE:To prevent scale-over and at the same time to always display clearly the fine increment/decrement of a graph, by providing a scale designating means to a print type electronic computer. CONSTITUTION:A keyboard KB includes a scale designation key SCL in addition to numerical keys NK, function keys FK and a graph print designation key G. The graph print maximum value, e.g., 400 is fed with the keys NK and then to a register R1 via a CPU. With a push of the key SCL, three data 0, 200 and 400 are fed to a printer PRT and at the same time the scale of a full scale 400 is displayed by a display DISP. Then 240G, for example, is pushed through the KB, and thus the maximum dot that can be printed after a division by 400, e.g., 60 obtained with multiplication of 100 is transferred to the printer PRT to print a length equivalent to share of 60 dots and then displayed DISP. In such a way, the full scale is freely controlled for each group of the data. Thus the increment/decrement of a graph can be clearly displayed.
