A tube spacer S formed by bending a wire, includes a plurality of projectionsand a base-bending portion. Each of the projectionsis inserted between tubes, and has a pair of extending portionsextend in X direction and a front-bending portionfor connecting both front ends of the pair of extending portions. The base-bending portionconnects both rear ends of the projectionsso that the projectionsare arranged at interval in Z direction. With this structure, manufacturing cost for the tube spacer S can be low, and the tubes can be stably supported.

Tube spacer, method of manufacturing the same, and heat exchanger

A heating apparatusincludes a shell, a primary heat exchanger (sensible heat exchanger), a burner (combustion means), and a fan. A secondary heat exchanger (latent heat exchanger)has a plurality of heat receiving tubesarranged in parallel between a pair of headersand, the heat receiving tubesbeing fixed to tube plates. The heat receiving tubesare bare tubes without fins and are arranged across flow of combustion gas. The number of the tubesarranged vertically is less than the number of the tubesarranged horizontally.

Heating apparatus

A secondary heat exchanger B for recovering latent heat from combustion gas includes water tubeseach of which is so inclined that a first endis positioned lower than a second end. Therefore, in draining water from each of the water tubes, water can be caused to flow smoothly into a water-inflow and hot-water-outflow headerA connected to the first ends. The secondary heat exchanger B includes a casingwhich includes an upper walland a bottom wallwhich are so inclined that the inner surfaces thereof extend generally in parallel with the water tubes, and the upper and the lower gapsandhave constant widths sand s. Therefore, the amount of heat recovery from the combustion gas passing through the gapsandcan be increased.

There is disclosed an agent for preventing the adhesion of thallium 201 to a container which comprises a reducing substance as an active ingredient. There is also disclosed a radioactive diagnostic agent wherein the adhesion of thallium 201 to a container is prevented which comprises thallium 201 and a reducing substance.

Method for preventing adhesion of thallium 201 to container

An ink jet head has an ink head main body that is constituted of a substrate, spacers that are formed on one side of the substrate, and a roof plate that is joined to the substrate through the spacers. One or more ink passages are independently formed between the substrate and the roof plate. Rows of piezoelectric devices, each of which is made of a plurality of piezoelectric devices aligned along each ink passage, are formed through the respective ink passages. Ac voltages whose phases are different from each other by 90 degrees are applied to the respective piezoelectric devices. Progressive waves, which are excited by the rows of piezoelectric devices, allow ink to move through the ink passage and to be sprayed.

An information recording and reproducing apparatus of the present invention, in which a tunnel current is utilized for recording information to a recording surface of a recording medium and/or for reproducing information from the recording surface, includes a slider which is arranged on the recording surface and floats above the recording surface by an air flow caused by movement of the recording medium. The slider includes a body having a first surface positioned opposite to the recording surface, a second surface parallel to the first surface, and a third surface oblique to the first and second surfaces. The slider further includes a cantilever having a projecting portion projecting from the body so as to be substantially parallel to the recording surface and a tip for detecting the tunnel current formed on a surface of the projecting portion on the side of the recording surface.
