Title: Specimen vaporizing chamber of gas chromatograph
Inventor: SATOU KATSUYA
IPC: G01N30/12
Filed: 1983-06-20
Abstract: PURPOSE:To make it possible to completely vaporize a specimen by preventing ingredients to be vaporized from being adsorbed by nonvolatile ingredients through such an arrangement wherein a heating mechanism to be installed to the specimen vaporizing chamber of a gas chromatograph is composed so that it is enabled to heat the vicinity of the carrier gas discharging hole of the gas chromatograph up to a temperature which differs from the temperature of the vicinity of the specimen injecting hole. CONSTITUTION:A specimen is injected by piercing the needle of an injector through the rubber stopper 4 of the specimen vaporizing chamber 1 of a gas chromatograph. The number of winding of a heat generating coil 7 is gradually reduced from portion A to intermediate portion B and portion C in order so that the number of winding of the coil 7 becomes larger at the injecting hole and in the vicinity of a carrier gas injecting hole 2, outer circumferential portion A, and the number of winding of the coil 7 becomes smaller at the outer circumferential portion C in the vicinity of a carrier gas discharging hole 3. By this arrangement, when a liquor is analyzed, for example, vaporization is prevented from becoming incomplete by preventing alcoholic ingredients from being adsorbed by water and extracted ingredients of high boiling point, and ingredients of high boiling point are prevented from being mixed in alcohol, and as a result of this, an accurate analysis can be performed.

Title: Balancing method of hollow shaft
Inventor: KIKUCHI KATSUAKI
IPC: F16F15/32
Filed: 1979-08-31
Abstract: PURPOSE:To correct the unbalance of a hollow shaft, by distrubuting a liquid-state material having a solidifying character to the inner surface of a central axis in the hollow shaft in such a manner as to obtain an equal inside radius and removing closing caps after solidification of the liquid-state material. CONSTITUTION:To an opening end at one side of a hollow shaft 4 the first closing cap 5 is fitted to seal a liquid-state material 6 having a character of being solidified with the lapse of time or the change of temperature, and then also to an opening end at the other side of the hollow shaft 4 the second closing cap 7 is fitted to make a rotating motion around the central axis of outer sides of the hollow shaft 4. During the rotating motion, the inside of the liquid-state material 6 tends to be balanced by a same centrifugal force, resulting in the production of an actual circle with the central axis O of the rotating motion as a center. After a completion of solidification of the liquid-state material 6, the rotating motion is stopped to remove the closing caps 5, 6 from the both ends of the hollow shaft 4. In this way, an uneven thickness of the hollow shaft 4 can be equalized by the liquid-state material 6 to cause a same result as that the hollow shaft 4 is machined in a good accuracy as though its thickness were constant at any place, and vibration is hardly generated in the hollow shaft when rotated in such a condition as described.

Title: Optical fiber probe for measurement of temperature
Inventor: HIRANO SHINSUKE
IPC: G01K11/20
Filed: 1996-05-01
Abstract: PROBLEM TO BE SOLVED: To correctly measure a temperature of an object with the utilization of an optical fiber by preventing influences of a cooling gas. SOLUTION: A ceramics cover 7 of a lower thermal conductivity than that of a cap 2 is provided via an insulating space 8 in the periphery of the cap 2 which is in touch with a wafer 4 via a phosphor 3. When the cap 2 comes in touch with the wafer 4, a temperature of the wafer 4 is measured from an attenuation time of an emission intensity of the phosphor 3. Even when an He gas 6 is supplied as a cooling gas from below the cap 2, the He gas 6 is not directly in touch with the cap 2 because of the presence of the ceramics cover 7. Moreover, the presence of the insulating space 8 prevents a thermal conduction between the ceramics cover 7 and cap 2.
