Filed: 1990-05-29
Abstract: PURPOSE:To quicken the focus speed by setting a focus area to three positions of upper part of screen, middle part of screen and lower part of screen, extracting each component of a video signal of each area simultaneously and discriminating rear focus, front focus or just focus. CONSTITUTION:An area gate 4 outputs a signal to extract three parts, a left area A of an uppermost area, a center area B and right edge area C of a lowermost area among a luminance signal outputted from a video signal processing circuit 3. A divider circuit 11 receives a peak of a high frequency component of the uppermost area A, and peaks of intermediate frequency and low frequency components to calculate a ratio of (high frequency signal level/middle, low frequency signal level). Divider circuits 12, 13 similarly calculate a ratio of a peak of a high frequency component of the center area B and the lowermost area C to a peak of middle and low frequency components. Based on the extracted components in this way, front focus, rear focus or just focus is discriminated. Thus, the speed of the focusing is improved.

Title: Differential pressure transmitter
Inventor: NISHIKAWA KIYONORI
IPC: G01L9/00
Filed: 1984-07-10
Abstract: PURPOSE:To prevent variation in operating pressure even when a pressure transmission medium expands or contracts owing to temperature variation by using an overpressure protecting mechanism which moves two pressure displacement elastic bodies to allow a seal member to abut on a case body or contact wall surface. CONSTITUTION:Pressures Pa and Pb (Pa>Pb) of fluid to be measured when applied are transmitted to a pressure sensitive element 29 through liquid shielding diaphragms 28a and 28b and pressure transmission media 30a and 30b and an output signal proportional to the difference pressure Pa-Pb is obtained. At this time, pressure displacement elastic bodies 22 and 23 and diaphragms 28a and 28b move to left. Then, when an excessive differential pressure exceeding a measurement range is impressed, the elastic bodies 22 and 23 move to left and the seal member 24b abuts on the contact wall surface 26b of a disk 25 to seal the medium 30b between the contact wall surface 26b and element 29. When a higher pressure is impressed and the elastic bodies 22 and 23 jog to left, the medium 30b increases in internal pressure because of non-compressive fluid and the impression of an excessive differential pressure to the element 29 is prevented, so that the generation of the excessive differential pressure is minimized even when the temperature rises in this state.

Title: Apparatus for preventing overheating of feed water pump
Inventor: KOBAYASHI SHIGEAKI
IPC: F04B49/10
Filed: 1979-11-05
Abstract: PURPOSE: To prevent the feed water pump from overheating, by keeping a predetermined flow rate of water automatically when the water flow rate of the feed  water pump is decreased with reduction of the load of a boiler.  
     CONSTITUTION: As the amount of water discharged from the pump is decreased with reduction of the load of the boiler, the discharge pressure of the pump is raised gradually to a critical overheat region. In connection with the above, the tensile force of a resilient member 8 is so selected that a connecting port 10 of a piston 7 is communicated to a port 9 formed in a casing cover 5 by a discharge pressure CR at the point immediately before the critical overheat region. By the discharge pressure raised to CR-point, piston 7 is moved to the right in an ablong hole 6 and ports 9 and 10 are communicated to each other, so tht a part of discharge water, that is, an amount of water corresponding to the minimum flow is released, for instance, to a deaerator disposed on the outside of the pump. Therefore, it is prevented that the water flow rate in the feed water pump is decreased to a level lower than a predetermined value. Thus, overheating of a feed water pump can be prevented positively.
