Abstract: PROBLEM TO BE SOLVED: To facilitate insertion and draws of a connector member even in the case connector is not positioned on the front surface of a box structure, in which a pluraility of printed circuit boards are accommodated, by providing possibility for the connector member to make parallel displacement. SOLUTION: Connectors 1 and 2 for connection of printed circuit boards are installed with possibility of parallel displacement by a flat cable 6 and a holding metal piece 4, and two rod members 4a, 4b are borne rotatably on the side faces of the connectors 1, 2 so that a parallelogram is formed which is capable of expansion and contraction. When one printed circuit board 7a is to be inserted in a box 8 and connected with another board 7b through the cable 6, the connector 2 is inserted to the board 7a, and the tip of the holder piece 4 is stretched, and the board 7a is inserted along a guide. This causes the other connector 1 to make parallel displacement toward the connector member 3 of the base board 7b, and the foremost of the board 7a contacts with the box 8 to complete connection of the connectors 1 and 3.  Thus the insert and drawout of connectors can be made easily without taking out other circuit boards from the box.

Title: Low nox burner for additional heating employing two-stage fuel burning method
Inventor: NABETA RYOSUKE
IPC: F23C99/00
Filed: 1985-11-21
Abstract: PURPOSE:To avoid a temperature in a duct from being risen to an abnormal high temperature locally and restrain the generation of NOx by a method wherein a nozzle for primary fuel and a nozzle for secondary fuel are provided so as to face to an exhaust gas flow path and air for stabilized combustion is sent only to the vicinity of the nozzle for the primary fuel. CONSTITUTION:Exhaust gas 12 is passed through a duct casing 3 and fuel is supplied so as to be devided to the nozzles 2 for secondary fuel respectively while air 8 for stabilized combustion is supplied only to the nozzle 1 for primary fuel. Oxygen exists in the vicinity of the nozzle 1 for primary fuel richly and flame is made in the vicinity 14 of the nozzle. On the contrary, fuel, injected out of the nozzle 2 for secondary fuel, moves to the downstream side of the nozzle 2 slightly and makes flame at a position 15 where at the fuel is joined with the remaining oxygen in the air 8 for stabilized combustion since the amount of oxygen in surrounding exhaust gas is insufficient. Combustion areas, formed by both of the nozzles, are deviated in the positions thereof and, as a result, the generation of NOx may be restrained.

IPC: G03B33/12
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a rear projection type video projecting device easily executing the adjustments of a focusing or the like. SOLUTION: The video light beam of each color passing through each liquid crystal panel for red, green and blue is synthesized by a dichroic prism 1 and is changed into a color video light beam. The color video light beam is led to a projection lens after changing an optical path in an upper direction by a prism 2 for changing the optical path, and is projected from the rear side of a screen. An adjustment mechanism for focus adjustment is provided at the liquid crystal panel. The focus adjustment is executed by changing the posture of a supporting plate 7 constituting a part of a supporting means supporting the liquid crystal panel 3. The posture of the supporting plate 7 is adjusted by inserting a minus driver into an adjusting cross recess formed by a hole 5a and a notch 7a, and the hole 6a and the notch 7a and rotating it.  The inserting direction of the minus driver is made nearly parallel with the direction of the color video light beam before changing the optical path. Thus, the adjustment is executed without covering a projection lens by the hand of an adjuster at the time or the adjustment and making a shade on the screen.
