Title: Method for turbine governor valve warming up control
Inventor: MURASATO KAZUNORI
IPC: F01D25/10
Filed: 1987-03-18
Abstract: PURPOSE:To prevent the generation of thermal stress by permitting the opening/ closing control of a bypass valve depending on the difference of temperature between the outer/inner walls of a steam chamber, as well as on the rate of temperature variation, on a machine warmed up by the opening/closing of the bypass valve provided so as to bypass a steam stop valve. CONSTITUTION:A steam supply line leading to a steam turbine consists of a steam stop valve 1 having a steam stop valve-bypass valve 2 and a steam governor valve 4 controlling a steam flow rate, being connected to each other in series, and the warming up of a steam chamber from the steam stop valve to the steam governor valve 4 is conducted through the opening/closing control of the bypass valve 2. In this case, the bypass valve 2 is controlled depending on a difference between the inner and outer wall metal temperatures, while the rate of temperature variation is monitored so that the aperture of the bypass valve 2 is held in such an aperture position as to be obtained when the rate of temperature variation exceeds its specified value, and it is controlled so as to be suppressed. This constitution prevents the generation of thermal stress due to a rapid change in temperature.

Abstract: PURPOSE:To make continuous treatment possible in a short time by permitting rewashing and separation with water in a field of centrifugal force after mixing solid particles of water soluble solid material dispersed in a water-insoluble solution continuously and dissolving, when resolving with the help of centrifugal force. CONSTITUTION:A heavy liquid in which a solid matter is dispersed is pumped up by a heavy liquid pump 9 together with a light liquid into a mixer 8, then the solid matter is allowed to be dissolved into the light liquid. After this, the dissolved mixture is permitted to be blown in the external peripheral direction of a rotor 1 from a heavy liquid dispersion pipe 2 of a centrifugal counter-current extraction device 7 to allow an initial dissolution, washing and separation process. Next, the separated heavy liquid is allowed to move to the external periphery of the rotor 1 and to be washed by the light liquid which blows out of a light liquid dispersion pipe 3 and moves to the internal periphery of the rotor 1 as the second washing process. Consequently, the heavy medium washed for the second time is conducted to the extraction device 7 through a heavy liquid outlet 5. In the meantime, both the light liquid which is introduced through the heavy liquid dispersion pipe 2 to be separated, and the light medium which has entered from the light liquid dispersion pipe 3 are moved in the internal peripheral direction of the rotor 1, and introduced to the exterior of the system from a light liquid outlet 4 via a back pressure valve 11 of the light liquid outlet.

Title: Copying machine
Inventor: SEZOKO SHINICHI
IPC: G03G15/04
Filed: 1984-03-30
Abstract: PURPOSE:To improve the copying operability of superposed originals and prevent miscopying by allowing an original surface on an original platen to be viewed. CONSTITUTION:When an original is placed on the original platen 3 with the original surface down, light from an auxiliary light source 9 is transmitted through the original, so the original surface is viewed and two originals (a) and (b) are superposed one over another easily and securely. When an original platen cover 11 is closed, a switch 14 is turned off and the auxiliary light source 9 turns off. Thus, normal exposure operation is carried out without being disturbed by the auxiliary light source 9, which needs not be turned on and off through special operation, so that a copy is taken by the same operation as before. The auxiliary light source 9 turns on and off associatively with the opening/closing operation of the original platen cover 11, so the light source 9 turns on and off automatically.

Filed: 1981-04-22
Abstract: PURPOSE:To reduce the number of signal transmitting lines between apparatus, by sending minimum bit numbers only which represent fluctuated amounts by checking in advance the fluctuating width of the program tracking prediction angle from figures of the prediction angle of a geostationary satellite, and planting the remaining constant value in an ROM. CONSTITUTION:Since a ground station which tracks a geostationary satellite knows the prediction angle of the satellite, a signal of the minimum bit number 9 representing the fluctuating amount of the prediction angle is transmitted from a program tracking device 1 to an antenna driving device 2. The bit of the remaining constant value of the prediction angle is set in advance in an ROM10 of the device 2. A tip selecting signal 12 is sent to the ROM10 together with the signal 9 and the signal 9 is made effective as an address input of the ROM10. By inputting a bit 11 of the constant value part from the ROM10 and the bit of the signal 9 into an error computing circuit 7 and by computing the difference between these bits and an antenna actual angle signal 6 in the circuit 7, a program prediction error signal 8 is inputted and sent to an antenna-servo system. Therefore, the number of signal transmitting lines between devices 1 and 2 can be reduced.
