Title: Method and apparatus for measuring stable isotope
Inventor: SAITOU TOMOO
IPC: G01N21/35
Filed: 1983-06-01
Abstract: PURPOSE:To measure a stable isotope quickly with a high sensitivity by converting a sample containing a stable isotope into a compound suitable for a laser infrared spectroscope to measure the absorption of a laser light by optoacoustic spectroscope. CONSTITUTION:A sample containing a stable isotope is separated with a sample separator 10 such as gas chromatograph and undergoes decompositions by oxidation and hydrogenation with a pretreating device 20 to be converted into a compound suitable for a laser infrared spectroscope. A laser infrared spectroscope 30 is based on the theory that absorption occurs in a utterly different oscillation ray in a molecule labeled by a different isotope. Light coming from a laser discharge tube 31 is incident into a sample cell 34 and absorbed passing through a chopper 33 to increase the pressure in the cell 34. Then, it is detected with a microphone 35 and recorded on a recorder 37 through a lockin amplifier 36.

Title: Light modulating element
Inventor: ONOKI SADAHIKO
IPC: G09F9/00
Filed: 1990-04-10
Abstract: PURPOSE:To improve the contrast of the light transmittance when a voltage is impressed or not by dissolving a random orienting material promoting the turbulence in the orientation of a liq. crystal molecule in a liq. crystal cell in the cell at least when a voltage is not impressed. CONSTITUTION:The liq. crystal molecules in the liq. crystal cell 20 dispersed in a transparent medium 21 are oriented along the medium wall as the boundary region in direction of the arrow under the influence of the wall when a voltage is not impressed to form a liq. crystal domain 201. Since the random orienting material 202 is dissolved in the cell 20, the material is finely divided from a liq. crystal domain 201, and disorder is increased as a whole. Consequently, the light scattering property is reinforced, and light transmittance of the light modulating element 2 is lowered. Meanwhile, when a voltage is impressed, the liq. crystal molecules are arranged and oriented in the direction of an electric field, and a liq. crystal domain is not formed. The molecules are easily moved and not disturbed, because the material 202 is dissolved in the cell 20. As a result, the contrast of the light transmittance of the element 2 is enhanced when a voltage is impressed or not.

IPC: C21C5/36
Filed: 1979-07-30
Abstract: PURPOSE: To accelerate dephosphorization and desulfurization reaction at small T and Fe amounts in slag by making the basicity of the slag ≥2.3 and employing a synthetic flux of CaO-Fe m O n  base for part of CaO as a slagging agent, at the time of performing steel making refining with an oxygen top blowing converter having a bottom blowing function.  
     CONSTITUTION: At the time of performing decarbonization and refining by oxygen blowing from molten scraps, etc. in an oxygen top blowing converter provided with bottom blowing lances, the basicity of molten slag is held at ≥2.3. At this time, CaO is used for the slagging agent of this basic molten slag in such a range in which the basicity becomes about 2.0 and a calcium ferrite base synthetic flux having the form of CaO-Fe m O n  is used as a slagging agent for forming the remaining basicity. The molten slag in which the activity of CaO in the molten slag is large and the FeO activity of 6W15% as T, Fe is small is formed. The oxidation slagging of P and the superior dusulfurization reaction by high basicity molten slag of small FeO activity are accomplished by the agitation and contact of the molten metal and the molten slag by bottom blowing.

Inventor: BABA TOSHIO
IPC: B65H5/06
Filed: 1998-03-25
Abstract: PROBLEM TO BE SOLVED: To provide a power transmission device in which gears can be easily recycled. SOLUTION: A first idler part 49 of an idler gear 29 is engaged with respective second gear parts 45, 55 of an output side gear 27 and an input side gear 31 to form a power transmission device 9. When mating gear parts are worn to be degraded, these respective gear parts are inversed to be capable of reassembling because unused gear parts exist.

Filed: 1980-07-17
Abstract: PURPOSE:To remove influence of the working temperature condition and electrical noises, improve reliability and reduce occupied volume, by receiving light transmitted through a slit disc with an optical fiber and by sending it directly to an external optical detector. CONSTITUTION:Light from an external light-emitting element 14 enters a light- emitting lens 8 via an optical fiber 16 and is focussed to irradiate a slit disc 6. Among irradiation light, light that passes through a fixed slit 12 is focussed with a light-receiving lens 10, enters an optical fiber 20 and is transmitted to an external optical detecting element 18. Accordingly, the output signal from the element 18 changes to a pulse signal whose number corresponds to the amount of revolutions of the disc 6. In this case, the body 2 of an pulse encoder is incorporated into, for instance, a servo motor.
