Title: Exhaust device for two stroke cycle engine
Inventor: YAMAMOTO MASAHIRO
IPC: F02B27/04
Filed: 1981-04-10
Abstract: PURPOSE:To obtain the stable promotion of output constantly between rotation areas low and high in an exhaust device with an expansion chamber by coveirng an exhaust pipe with heat-insulating materials in the range between the engine side end and the end faced to the expansion chamber. CONSTITUTION:In an expansion chamber 4, a reflection wave to return to the engine side is caused, and when the temperature of exhaust gas is high, the speed of the reflection wave is accelerated. However, since the ignition timing is delayed in the area of high rotation, the size and the shape of an exhaust pipe 1 adjusted to the area of low rotation can be adapted for the timing of the relfection wave, and the output can be promoted even in the area of high rotation. But, since the exhaust pipe 1 is directly exposed to the open air,,the periphery of the exhaust pipe 1 is wrapped up by heat insulating materials 10 not to disturb the effect of the high-speed lag angle caused by the lowering of temperature of the exaust gas in the exhaust pipe 1. This consturction permits to prevent the lowering of temperature and ensure the speed of the reflection wave for obtaining a fixed promotion of output by the set high-speed lag angle.

Abstract: PURPOSE:To enable a high-precise analyzing of a sample containing a plural number of organic compounds without refining-isolating, by a method wherein a gas chromatography is combined with an element analyzer. CONSTITUTION:An organic compound sample fed through a pouring port 2 is fed to an analysis column 3 by means of a carrier gas 1. The organic compound in the sample is separated during th passage of it through the analysis column 3 filled with a filler. A part of mixture gas flowed out enters into a hydrogen flame ionizing detector 4 through a resisting pipe 10, and most of the rest is mixed with an oxygen 5 to be fed to a combustion pipe 6. The organic compound in the combustion pipe 6 is burned into NO2, CO2, H2O and other gases, and flows into a reduction pipe 7. Gas, flowing out of the reduction pipe 7, is prepared into a mixture of CO2, H2O and N2 to the carrier gas, and is separated into N2, CO2, H2O gases by means of a separation column 8 to reach a hgh-sensitive detector 9 against an inorganic gas.

Title: Method for judging joint of strip shaped body
Inventor: HIGUCHI MITSUO
IPC: B29D30/08
Filed: 1989-03-06
Abstract: PURPOSE:To make it possible to judge the quality of a joint accurately and positively by averaging a plurality of reference data, obtaining a reference value, and inputting displacement data into reference data sequentially when the thickness data of the difference between the displacement data obtained for each sampling and the reference value are within the comparison data for storing the reference data. CONSTITUTION:A rotary drum 1 is rotated. The displacement of an outer strip shaped body 4 is intermittently sampled and measured with non-contact type displacement gages 8 and 9. The displacement data L are compared with a reference value (x). Thus, the quality of a joint 7 where both ends of the strip shaped body 4 are overlapped is judged. Namely, a plurality of reference data (a) - (j) are averaged, and the reference value (x) is obtained. The thickness data x' of the difference between the displacement data L and the reference value (x) are obtained for every sampling. When the data x' are within a comparison value H for storing the reference data, the displacement data L are sequentially inputted in the reference data (a) - (j). As a result, even if there are irregularities and the like on the surface of the strip shaped body 4, the reference value (x) can be obtained in consideration of the irregularities. Thus the quality of the joint 7 can be judged accurately and positively.

Title: Semiconductor laser element
Inventor: KAYANE NAOKI
IPC: H01S5/00
Filed: 1986-03-14
Abstract: PURPOSE:To reduce astigmatism by forming a laser resonator to a curved- surface shape in a semiconductor laser having stripe width in which a single transverse mode is obtained. CONSTITUTION:A sectional shape in a plane parallel with an active layer for a laser resonator, a semiconductor end surface, is formed to a curved-surface shape. Spot width is narrowed in a cross section such as a convex end surface 1 while the radius of curvature of a wave front (a phase front) is increased with the decrease of the radius of curvature R of the end surface, reaches infinity and takes a negative value and the absolute value is reduced again. On the other hand, spot width is broadened in a concave end surface 2, and the radius of curvature of the wave front is decreased with the shrinkage of the radius of curvature R of the end surface. Accordingly, since the end surfaces are formed to the curved-surface shape, spot width and the redius of curvature of the wave front can be altered, thus reducing astigmatism.

Title: Tape cassette
Inventor: YOSHII TETSUJI
IPC: G11B23/087
Filed: 1979-05-04
Abstract: PURPOSE: To stabilize the run of a tape by automatically braking a couple of guide rollers at the upstream side of a tape run.  
     CONSTITUTION: When tape 4 is driven as shown by the arrow, tape-run-direction follow-up member 14 at the upstream side of the run of tape 4 comes in contact with guide roller 8 by turning clockwise through the run of tap 4, and consequently guide roller 8 is braked and inhibited from turning. Tape-run-direction follow-up member 13 at the downstream side, on the other hand, is turned counterclockwise to come in contact with tape guide pin 10, and guide roller 7 is therefore turned following up the run of tape 4. Once the run direction of tape 4 is reversed, tape- run-direction follow-up member 13 comes in contact with guide roller 7 and tape- run-direction follow-up memeber 14 meets tape guide pin 11. Thus, guide roller 7 is bracked and the tape is given back tension by friction with stopping roller 7, thereby stabilizing the run of the tape.
