Abstract: PURPOSE:To obtain a new compound, composed of a peptide having a specific molecular structure, capable of manifesting high surface activity, having high biodegradability and useful as a strong detergent, for tertiary recovery of petroleum, etc., by culturing a bacterium of the genus Arthrobacter and recovering the resultant product. CONSTITUTION:Soil near a Sagara oil field in Japan is suspended i sterile water and an agar culture medium precoated with the oil produced therefrom is further coated with the resultant suspension to carry out the culturing at 28-37 deg.C for 2 days to 1 week. An appearing colony is then collected to isolate a bacterium which belongs to the genus Arthrobacter and is capable of producing a biosurfactant [e.g. Arthrobacter.sp. No. 38 strain (FERM P-13198)]. The isolated bacterium is then inoculated into a culture medium and cultured at 30 deg.C for 24hr. The culture supernatant is subsequently separated and concentrated with an ultrafiltration membrane and 50mM CaCl2 and 10mM hydrochloric acid are then added thereto to form a precipitate, which is subsequently recovered and purified by a silica gel column, etc., to afford the objective new compound, expressed by the formula and having high surface activity.

Title: Quenching method for preventing heat treating strain in case hardening steel
Inventor: EGUCHI TOYOAKI
IPC: C21D6/00
Filed: 1997-07-18
Abstract: PROBLEM TO BE SOLVED: To unnecessiate modifying grinding for the shape of a steel after carburizing and quenching without using a steel having a special componental compsn. by subjecting a case hardening steel to carburizing treatment and diffusing treatment under specified conditions, then executing cooling and thereafter subjecting it to quenching. SOLUTION: At first, a case hardening steel is subjected to carburizing treatment at the A3 +50 deg.C or above in a medium having 0.8 to 1.4 wt.% carbon potential. Then, the carburized case hardening steel is subjected to diffusing treatment to reduce the concn. of carbon in the surface layer part to 0.6 to 0.9 wt.%. This steel is cooled in the two phase temp. region of austenite/ferrite in the temp. range of above the A1 +10 deg.C to the A3 at a cooling rate of 0.1 to 5 deg.C/min to produce ferrite in the range of 10 to 50% by area as for the microstructure in the noncarburized part of the steel, and after that, quenching is executed from the temp. of the A1 +10 deg.C or above.  In this way, stress caused by the volume expansion to accompany martensitic transformation at the time of carburizing and quenching is absorbed into the ferrite forming region to prevent the generation of strains.

Filed: 1981-12-04
Abstract: PURPOSE:To prevent the deterioration of the reliability when a data is transmitted asynchronously, by providing a state informing means between a pair of CPUs having an information exchanging means in order to inform the own RUN state to the other side. CONSTITUTION:The working state is informed to each other between CPUs 2 and 3 by means of the data buses DA and DB, and each working state is transmitted along with the transmission data. When the transmission becomes asynchronous due to a fault of the CPU2 of the slave side, a CPU5 coupled to the CPU3 of the master side receives the data via a system bus A likewise in a normal mode and continues the arithmetic process. On the other hand, a CPU4 which is hitherto receiving the data from the CPU2 via a system bus B detects an asynchronous transmission state from the contents added to the data and then switches a switch S1 to a contact a1 from b1 with use of the contact switching signal 7. Then the CPU4 receives the data from the CPU3 via a switching bus A and continues an arithmetic process in a synchronous state.

Title: Test piece for measuring displacement
Inventor: ONO TAKASHI
IPC: G01N3/08
Filed: 1995-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent the fracture of a test piece from the boundary section between a projecting section and a section to be measured during tests so that measurement can be performed with high accuracy by controlling the curved surface of the boundary section so that the curved surface can meet a specific condition. SOLUTION: The boundary section between a projecting section 3 and a section to be measured of a test piece 1 is constituted of two different continuous curved surfaces having different radii of curvature. Therefore, the change of the curved surface from the section to be measured to the section 3 can be controlled easily and, at the same time, the fracture of the piece 1 from the boundary section between the section to be measured and the section 3 can be prevented without changing the distance between projecting sections. In addition, the test piece is formed so that the ratio (d/R) of the diameter (d) of the section to be measured to the radius of curvature (F) of the curved surface at the boundary section between the section 3 and the section to be measured of the piece 1 can become 0.3. Therefore, accurate measurement can be performed, because the concentration of stresses to the boundary section can be eliminated and the test piece 1 is not fractured from the boundary section during tensile tests.
