Title: Fixing method by screw
Inventor: MATSUMOTO KAZUO
IPC: F16B39/02
Filed: 1988-12-01
Abstract: PURPOSE:To prevent a thread of a threaded handle from being slackened by vibration by constituting a joining system by means of both threaded handle, which is used to fix a joining body to a body to which the joining body is joined (hereafter referred to as 'joined body') and a lever, which is installed in such a manner that it is rotated by a spring so as to be fitted in the threaded handle. CONSTITUTION:When a joining body 2 comes to a fixing position, a lever 4 is pushed in the arrow-marked direction, so that the lever 4 is disconnected from a groove of a threaded handle 3. Next, the threaded handle 3 is rotated until the joining body 2 contacts a 'joined body' 1. At this time, the released lever 4 is fitted in the nearest one of a plurality of grooves grooved on the threaded handle 3. Thus, even if vibration or large force acts on the joining body 2, the lever 4 will not be disconnected from the groove of the threaded handle 3, owing to the force of a spring 5. At the same time, the threaded handle 3 will not rotate in the direction in which the handle is slackened. Therefore, the joining body 2 can firmly be fixed to the 'joined body' 1.

Title: Continuous soaking method for thin metallic sheet
Inventor: MATSUBARA SHIGEJI
IPC: C21D11/00
Filed: 1988-12-02
Abstract: PURPOSE:To prevent the unequal heating of a thin metallic sheet by the fluctuation in the transverse direction thereof by providing a mechanism which moves a conductor coil for induction heating of the thin metallic sheet horizontally back and forth at the required amplitude with respect to the metallic sheet. CONSTITUTION:The conductor coil 2 is energized and the thin metallic sheet 1 is made to travel therein by which the induction heating is executed. The transverse direction detection signal of the metallic sheet 1 from a detector 12 is sent to a computing element A and the deviation signal thereof is changed by a relational computing element B to the coil follow up quantity. This follow up quantity is sent to a servo amplifier C. The position signal of the coil 2 is sent from the detector 11 to a computing element D and the deviation signal thereof is sent to the servo amplifier C so that the coil 2 is moved by a hydraulic cylinder 10 so as to follow up the metallic sheet 1. On the other hand, the position signal of the coil 2 from a forward and backward movement detector 25 installed to a servo motor 24 is inputted to a forward and backward quantity computing element G, by which the signal is compared with a set value. The horizontal forward and backward movement quantity of the coil 2 is thus corrected. Further, a relational computing element K outputs the correction value to a servo amplifier I from the speed signal of the metallic sheet 1 from a traveling speedometer 14 and the speed signal of the coil 2 from a forward and backward speed detector 26, thereby correcting the horizontal forward and backward movement.

Title: Sonar apparatus
Inventor: HISADA MASAHIRO
IPC: G01S15/06
Filed: 1991-10-25
Abstract: PURPOSE:To improve accuracy in measurement of a distance and an azimuth. CONSTITUTION:A sonar apparatus moves from a point 1 toward a point 4, while a target moves from a point 5 toward a point 7. When the sonar apparatus transmitted sound waves at the point 1, the target is positioned at the point 5, but the target reflects the transmitted sound waves at a point 6. At this time the sonar apparatus has moved to a point 2. Then the sonar apparatus receives reflected sound at a point 3 to which the sonar has further moved, but at this time the target has moved to a point 7. The distance Rr is obtained by using the moving speed Vs of the sonar apparatus, the distance and the angle B obtained from the time interval between transmission and reception and sound wave speed, and then the distance Rr, sound wave reception time and the sound wave speed are used to obtain time Tx when the sound waves were reflected at the point 6. Since the distance between the points 2 and 3 is a product of Vs and Tx, a cosine formula is applied to a triangle having vertexes at the points 3, 2 and 6 to obtain a distance between the points 2 and 6 and an angle of the vertex 2. Thus the distance and the azimuth angle at the time when the sound waves are reflected on the target can be correctly obtained.
