IPC: F03B15/18
Filed: 1978-07-07
Abstract: PURPOSE: To quickly stop a water wheel generator in the trouble of a control hydraulic system and prevent an accident, by detecting the disappearance of oil pressure from the hydraulic system and shutting off a servomotor.  
     CONSTITUTION: When pressure oil or oil pressure in a tank 3 disappears or abnormally decreases due to the trouble of the control hydraulic system, an oil detector 7 or an oil pressure detector 8 detects the disappearance or the abnormal decrease to actuate a protector 9. Emergency shut-off valves 10, 11 for an input and an output outlet passages of opening and closing oil for the servomotor 5 are closed by the output of the protector 9. At the same time, an emergency pump 12 is started to transfer the pressure oil of the cylinder of the servomotor 5 from the open side to the closed one in the direction of the arrow in Fig. to shut off the servomotor.

Title: Magnetic disk device
Inventor: TAKAHASHI MINORU
IPC: G11B23/50
Filed: 1985-04-16
Abstract: PURPOSE:To self extinguish stains or minute flaws sticking on a surface of a magnetic disk and reproduce at an early time and to raise an alarm when they cannot be reproduced by detecting a head touch with a good sensitivity by an AE sensor bonded to a core slider, and lowering the number of rotations of the magnetic disk to seek. CONSTITUTION:A rotation control section 5 retards a rotating speed of a magnetic disk 1 for a predetermined time through a rotating motor 9 by a head touch signal from an AE sensor and lowers an amount of floating of a floating type head 2. During the predetermined time, a seek control section 6 seeks the floating type head 2 in reciprocation radially of the magnetic disk 1 through a linear driving mechanism 4. By this low floating head seek, attachments on the surface of the magnetic disk are removed. After the retardation, when being activated again at an original steady rotating speed, a counter 7 starts to count an output of the AE sensor 3 and when the counted value goes to >=2, stops a rotation through the rotary control section 5 and the linear driving mechanism 4 and drives an alarm circuit 8 to output an alarm signal.

Title: Unwinding device of textile spreader machine
Inventor: TAGAWA KEIKO
IPC: B65H16/10
Filed: 1982-05-15
Abstract: PURPOSE:To provide possibility of a constant amount of unwinding at all times by furnishing an unwinding roller, which turns in pressure contact with the material roll, at the body of a textile spreader machine with possiblity of as well rotation as vertical motion and by adjusting this vertical motion with an operational leve and a balance weight. CONSTITUTION:When a material roll 5 is loaded at the end of a suppor arm 4 and put in contact pressure with an unwinding roller 6 located at the top position of a longitudinal hole 10, this unwinding roller 6 will begin sinking. When this sinking swings the short member of an operational lever 15 downward and the long member upward, a roller 19' of a limit switch LS 19 will be dislocated from a recess 20' of cam 20. Thus the LS19 is turned off. Thereby drive of the support arm is stopped and rotation of the unwinding roller 6 will now unwind the material roll 5. When unwinding proceeds for the roll 5 to attain the minimum diameter limitation, effect of a balance-weight 11 will turn back the operational lever 15 for a certain specific angle, and turning-on of the LS 19 will swing the support arm 4 again downward. Thus unwinding is performed continuously.

Title: Ink arrangement for rotary printing machine
Inventor: BUORUFUGANKU OTSUTOO REEDAA
IPC: B41F31/02
Filed: 1991-04-15
Abstract: PURPOSE: To obtain an ink chamber doctor compensating pressure fluctuation in an ink chamber for the anilox roller of an inking unit by providing a doctor blade having a large free bending length as compared with the thickness. CONSTITUTION: In the inventive inking unit, a free bending length L (e.g. L=40 mm) is attained for each doctor blade. Doctor blades 7, 8 having the ratio of the free length L to the thickness D less than 400 are remarkably flexible. Since these doctor blades 7, 8 are bent significantly, although not constantly, upon receiving a pressure, they are extremely sensitive to pressure fluctuation in an ink chamber 9. Consequently, pressure fluctuation in the ink chamber is suppressed and a cell can be filled well with ink.
