Abstract: PURPOSE:To perform the quantitative analysis classified by form of carbide contained in steel, by decomposing the carbon extraction residue in steel while changing heating temp. to analyze the generated gas. CONSTITUTION:The carbide of the specimen 9 in a reaction furnace is decomposed under heating in an oxygen stream introduced from an oxygen inlet 14 to be sent to a reaction completion furnace 2 as decomposed gas and again heated to be perfectly converted to CO2 which is, in turn, sent to an analyser through a CO2 outlet 28 to measure the amount of CO2.

Title: Springback volume prediction method
Inventor: TSUTAMORI HIDEO
IPC: B21D5/00
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To improve prediction accuracy of springback volume in a method for predicting a springback volume, namely, elasticity recovery volume of a material after completion of plasticity processing. SOLUTION: With thus prediction method, an experimental value of stress- distortion relationship concerning an experimental piece is obtained by a tensile- compression test in connection with a given distortion, which being a plasticity distortion at the beginning of load elimination (S1). Based on the obtained experimental value, a material characteristic value needed for prediction of spring back value is obtained in connection with the given distortion by approximating the stress-distribution relationship with a linear material hardening model (S2). Initial distortion which being a plasticity distortion existing right after a plasticity processing is predicted concerning each element of a material being divided virtually (S4).  Material characteristic value corresponding to a predicted initial distortion is determined by way of using the material characteristic value obtained in connection with the given distortion. Springback value is then predicted based on the determined material characteristic value (S7).

Title: Magnetic head and magnetic recording and reproducing device
Inventor: KOMODA SUMITOSHI
IPC: G11B5/187
Filed: 1984-06-14
Abstract: PURPOSE:To have no influences of a leaked magnetic flux upon the effective track width of a recording track recorded in advance, by allowing one corner part of two cores to coincide with each other in the gap forming part of these cores. CONSTITUTION:Since a corner part 34 and a corner part 36 in a gap forming part 32 of an R azimuth head 37 and an L azimuth head 38 indicated on a recording pattern extension coincide with each other, a special gap other than the essential gap is not formed between the corner part 34 and the corner part 36 of the head 38 recording later, and a normal track width 24 on a magnetic tape 21 due to the head 37 recording first is not affected by the leaked magnetic flux. Parts 39 and 40 where information recorded on the magnetic tape 21 is disturbed are generated by the leaked magnetic flux in a special gap between corner parts 33 and 35 which do not coincide with each other. Since the track pitch of the R azimuth head 37 and that of the L azimuth head 38 are equal to each other, this part 39 is erased, and correct information is rewritten. Thus, high-density recording and reproducing of good S/N is possible.

Title: Callable area control method for phs
Inventor: WATANABE MASAHIDE
IPC: H04B7/26
Filed: 1995-05-22
Abstract: PURPOSE: To reduce a blind sector area without requiring large cost by controlling the callable area of a PHS base station through adjustment of the height of an antenna. CONSTITUTION: It is checked whether any blind sector is caused in a prescribed PHS service area that includes base stations 1 to 5. Then every base station has a height/position adjustable antenna, so that the callable area of the base station can be controlled through adjustment of the antenna height. The callable area is generally expanded because antenna height is increased and therefore the blind sector is reduced. At the same time, prescribed maintenance job is required in the service area because a blind sector is also caused by the environmental conditions including the buildings, etc. Thereby, the blind sector can be eliminated by improvement of the transmitting capability of base stations or extension of these stations.
