Title: Safety device for steam valve
Inventor: KOBAYASHI MASARU
IPC: F01D17/10
Filed: 1985-10-02
Abstract: PURPOSE:To prevent leakage of steam staying in a gap defined between a cap of a steam valve and a pusher member, by leading a steam pipe from the gap, and opening an openable valve in the steam pipe when a steam temperature and a pressure in the pipe reaches respective predetermined values. CONSTITUTION:A pressure seal ring 15 is provided at an upper portion of a steam valve body 1 in such a manner as to be held by a pusher member 16. A cap 20 is placed on the upper end of the valve body 1 with a gasket 19 interposed therebetween. The cap 20 is formed with a steam bleeding hole 30 comunicating with a gap 27 defined between the pusher member 16 and the cap 20. A steam pipe 32 connected at its one end to the steam bleeding hole 30 is led therefrom through an electromagnetic selector valve 33 to the outside area. The selector valve 33 is controlled by an opening/closing signal generator 37 receiving signals from a tempereture detector 34 and a pressure detector 35. When the leaked steam stays in the gap 27, the selector valve 33 is opened to bleed out the staying steam. Thus, there is no possibility of the steam being leaked from between the steam valve body and the cap.

Title: Fault detector for working control system
Inventor: MANABE KUNPEI
IPC: G05B19/042
Filed: 1984-10-19
Abstract: PURPOSE:To detect a fault and its factor with transmission of a control command by detecting at the side of a sequence controller that no control command is transmitted owing to a fault at the side of a computer and storing the control state at the side of the computer in response to the result of said detection. CONSTITUTION:A control means E within a computer A replaces the internal storage of various types of control information in response to the progress of the working control. At the same time, the means E detects through a fault detecting means C of a sequence controller C that no control information is delivered normally from the computer A. Thus a fault signal is sent to the computer A, and the control information is stored in the memory means D. Thus the progress state of the working control obtained in a faulty mode is stored to the means D together with the control information including a command signal. Then the state of the fault can be known by printing out the contents of the means D even in case a worker destructs the state set in a faulty mode for restart of working.

SOLUTION: The optical path control plate 1 comprises the plate which periodically has the stripe grooves 11 consisting of the gentle slopes 12 of 5 to 30 deg. in the angle of inclination with a base material plane and steep slopes 13 of >=60 deg. on the one surface of the transparent base material and periodically has the stripe grooves 14 consisting of slopes 15, 16 of 30 to 50 deg. in the angle of inclination with the base material plane on the other surface of the transparent base material. The light exit side of the light transmission plate which emits the incident light from the light source arranged on the flank as the stripe patterns of bright parts and dark parts from one of the front and rear surfaces is provided with the optical path control plate 1.  As a result, the optical path of the directivity emitted from the light transmission plate may be converted with good directivity to the state more approximate to the perpendicular direction via refraction. While the degradation in the luminance by diffusion is prevented, the directivity of the bright lines emitted from the light transmission plate is well maintained without the collapse by diffusion and dispersion, by which the optical path convertion is made possible.
