Title: Structure for switching of flow passage
Inventor: HIROKI KOUJITSU
IPC: B01D61/08
Filed: 1982-01-13
Abstract: PURPOSE:To provide a structure for switching of flow passages which is small in the number of parts and permits easy attaching and detaching of members by  providing a recess corresponding to the ends of a pair of separating tubes to a  header, and interposing a sealing member having a peripheral part corresponding  to said recess. CONSTITUTION:Supporting pipes 3 mounted with membranes 4 are pressed and fixed to a tube plate 5. Inserting parts 7a, 7b of a sealing member 6 are inserted into the tube ends and are pressed to the inside walls of the membranes 4 by expanding members 15a, 15b. An edge part 10 is formed around the connecting part 9 of the member 6 and the part 10 is pressed to the plane end face 13 of a header 12 having a recess 11, by which the fluid tightness of the flow passages is assured. Even if sponge balls, etc. are moved for the purpose of cleaning of the membranes with such structure, the recess 11 which is a switching part for flow passages is large in space; therefore, the damage of the sponge balls is decreased and the pressure drop is reduced as well.

Filed: 1979-01-13
Abstract: PURPOSE: To attain miniaturization and reduction in cost with constitution simplified by applying a reverse-current preventive diode with a voltage obtained by rectifying and smoothing a voltage across the primary winding of the transformer of a DC power circuit.  
     CONSTITUTION: Alternating-current power supply 1 is connected to DC power circuit 2' to develop voltage V 1  across smoothing capacitor 4 and also to apply reverse- current preventive diode 5 with voltage V 2  obtained by rectifying and smoothing the acorss voltage of the primary winding of the transformer of DC power circuit 2'. Both those voltages V 1  and V 2  cause superposing capacitor 6 to develop its high across voltage V 1 +V 2 , which is applied from output terminal 7 to a load to gennerate an arc. Once the arc is generated at the load, load impedance lowers and voltage V 2  also falls to supply voltage V 1  across the load.

Title: Encapsulating method for bulb
Inventor: GOTOU EIZOU
IPC: H01J9/26
Filed: 1980-01-18
Abstract: PURPOSE:To improve the yield during the encapsulation and to enable rigid brazing, by applying the glass brazing only on the inner face side at the open end of bulb thereafter thermally fusing it to encapsulate the stem and the bulb. CONSTITUTION:The open end Ba of a bulb B is immersed in a glass suspention Gs and after picking-up the glass brazing adhered at the outside face is wiped out, then the glass brazing Gi is applied only on the inside face and the end face at the open end Ba of the bulb. Thereafter the stem S is inserted into said bulb B and the flare Sa is positioned at the open end of the bulb to fuse the glass brazing Gi while heating with the burner flare to encapsulate them. Since the stem is encapsulated without applying the glass brazing on the outside face of the bulb, the glass is never distorted to prevent the crack and the yield during the encapsulation work is improved.
