Title: Screen printing machine
Inventor: TAKEUCHI AKIRA
IPC: B41F15/20
Filed: 1990-03-20
Abstract: PURPOSE:To improve a snap off of a green sheet and a screen by avoiding sticking of both by a method wherein a processing part composed of a printing base on which the green sheet is put fixedly and a plate frame to which the screen is disposed in tension is provided, and a pushing member having elasticity is provided to the plate frame. CONSTITUTION:A processing part 23 composed of a printing base 22 on which a green sheet 40 is fixedly put and a plate frame 24 to which a screen 26 for pattern printing arranged above the printing base is disposed in tension is established, and pushing members 28a, 28b having elasticity are arranged to the frame. Therefore, in the case where a squeegee 60 is displaced, since the pushing members 28a, 28b push an end part of the green sheet 40, the green sheet 40 is never transferred to the screen 26 side by adhesion of a paste 50. Further, a snap off property can be steeply improved because of a clearance to be generated by a thickness of the pushing member and its elasticity.

Abstract: PURPOSE:To constitute so that water in a reservoir does not evaporate even when a turbine has started or when a load has dropped suddenly, and also water in a penstock does not freeze in the winter season, by making a part of condensate flow into a high pressure side penstock and cooling the water in the reservoir. CONSTITUTION:A part of condensate is led to a penstock 9 of a high pressure side H of a differential pressure transducer 6 through a water-conveyance pipe 11 and a flow rate control valve 12 on the way of a condensation pipe 1 for feeding condensate to a deaerator 2, and a chilled water is always supplied into a reservoir 8. Also, a penstock 7 for connecting the reservoir 8 and the upper part of a water storage tank 4 is inclined downward from both sides and formed in a Y-shaped pipe, and a combined pipe 13 is connected to the lower part of the water storage tank 4. According to such a structure, a reference head water in the reservoir 8 is always cooled by a part of a chilled condensate, therefore, no evaporating phenomenon occurs in any time. Also, water in the high pressure value penstock 9 of the differential pressure transducer 6 always flows in the upper direction and does not stay, therefore, there is no danger of making said water freeze in the winter season.

Title: Charged state visually recognizing system
Inventor: KOBAYASHI KENICHI
IPC: G01R29/24
Filed: 1979-06-07
Abstract: PURPOSE: To recognize visually a charged body for charged portion and its quantity by a system wherein the charged body is pushed onto an image pickup tube to transfer a charged state to a target of the image pickup tube, and then the target is scanned with an electron beam.  
     CONSTITUTION: From pushing a charged body Mk onto a dielectric thin film Is, a charged state of the body Mk is transferred to a photoconductive film Pr 2  (target) by way of the dielectric thin film Is. When a plus charge is present on the target, the plus charge is decreasing through scanning with an electron beam from a cathode Pr 3  and a charging is carried out from a power supply through an electrode Pr 1 , therefore it is sent to a display Dr as signal to indication. Since a white (high brilliant) display appears, as illustrated, on a cathode ray tube CRT of the display Dr, the charged state of the body Mk can be recognized by observing its position, shape and area.
