Title: Rolling method for rough shape billet
Inventor: KUSABA TAKASHI
IPC: B21B1/08
Filed: 1981-04-13
Abstract: PURPOSE:To avert the sinking, crazing and crop formation of flanges in the stage of rolling a billet of a dogbone sectional shape to an open hole shape by performing a rolling reduction only the web part in such a way that the ratio of the sectional area of the unrolling-reduction part with attains specific values respect to the entire sectional area of the material to be rolled. CONSTITUTION:A dogbone-shaped blank material 11 is subjected to rolling reduction at only the web part with upper, lower rolls 14, 16 without performing rolling reduction on its light rolling reduction flange parts 24. The conditions for the rolling-reduction are so set at to attain SFO/S0>=0.6 when the entire sectional area of the material 11 is defined as S0 and the unrolling reduction part as SFO. Since the web is reduced of area while the reduction in the sectional area of the parts 24 in this way, the web is restrained by the flanges which are not rolling reduced and the elongation by the rolling reductions is suppressed.

Title: Target detecting apparatus
Inventor: KUNO HARUYOSHI
IPC: G01S3/808
Filed: 1989-03-07
Abstract: PURPOSE:To make it possible to detect the azimuth angle and the elevation angle of a target by attaching a pair of microphones and a level to a helmet of a target searching person, and detecting an angle between a reference line and the looking direction of the searching person and the elevation angle viewed up by the searching person. CONSTITUTION:Target searching persons B1 - B4 wear helmets 11 and carry transmitting devices 12. The searching persons are posted with a missile launcher A as the center so that each person is in charge of the sector of about 90 deg.. Microphones 15 and 16 are attached to the positions of both ear parts of the helmet. Sound waves from a sound source 13 at the launcher A are collected into the microphones. A level 17 is attached at the top part of the helmet 11. A specified frequency component is taken out of each collected sound signal obtained through the microphones 15 and 16. The phase difference between the components is detected. An angle formed by a reference line connecting the sound source 13 and the position of the searching person and the viewing direction of the searching person is detected from said phase difference, the specified frequency and the distance between the pair of the microphones 15 and 16. The angle is subtracted from the azimuth angle of the reference line. Thus, the azimuth angle of the target is obtained. The looking-up angle of the searching person is detected based on the inclination of the level. The elevation angle of the target is obtained based on said angle.

Title: Method for cleaning wafer
Inventor: MAKITA MASAHIRO
IPC: H01L21/304
Filed: 1993-02-22
Abstract: PURPOSE:To obtain a great cleaning effect without using a cleaning solvent beyond a necessary amount and, at the same time, to uniformly clean the surface of a wafer by cleaning the wafer while the flow velocity distribution of the cleaning solvent in a cleaning tank is changed. CONSTITUTION:A wafer 7 to be cleaned is mounted and held on a supporting member in a cleaning tank 1. The tank 1 is filled up with a cleaning chemical and the chemical overflowing the tank 1 is collected in an overflow tank 2. The chemical collected in the tank 2 is circulated in the direction shown by the arrow A by means of a pump 4 and supplied into the tank 1 from the bottom of the tank 1 through a filter 6. The supplying amount of the chemical collected in the tank 2 is not fixed, but changed by controlling, for example, the drive of the pump 4. As a result, the flow velocity distribution of the chemical in the tank l varies. Therefore, the reliability of the cleaning action of the cleaning chemical is improved and the surface of the wafer can be efficiently and uniformly cleaned.

Title: Web feeder
Inventor: HASHITOMI MASAAKI
IPC: B41J15/04
Filed: 1985-03-19
Abstract: PURPOSE:To improve the operability at the time of replacing and setting webs, and to reduce the required space by separately forming a support member for a web feed auxiliary roller and a support member for a web pressing plate, so that only one support member is operated to press the web and the auxiliary roller. CONSTITUTION:At the time of installing a web 23, a claw 12 is detached from a fixed table 13 to turn a support member 9 on a shaft 10. A support member 8 is a little turned by elastic force of a spring 21 to separate a feed roller 20 and an auxiliary roller 2 from each other. In such a condition, after a web 23 is set, the support member 9 is turned in the returning direction, so that a shaft 17 is brought into contact with the surface B of the support member 8. When the support member 8 is further turned, a spring 18 is compressed. With such compression, the support member 8 is turned to bring the auxiliary roller 2 into contact with the feed roller 20. The movement of the support member 9 is further continued to hook the claw 12 on the fixed table 13, whereby the support member 9 is fixed. Thus, at the time of replacing and setting the web 23, only the support member 9 to which a pressing plate 7 and the like are fixed may be turned, and it is not necessary to move the auxiliary roller 2.
