IPC: F25B39/02
Filed: 1998-12-10
Abstract: PROBLEM TO BE SOLVED: To reconcile the improvement of the drainage of condensed water and the heat conductivity of the fin. SOLUTION: In a tube 2 flat in cross section arranged to extend vertically, a drainage ditch 10 to guide condensed water downward is made in the middle section in the direction A of an air current, while in a corrugated fin, space 53 is made in the section opposed to the drainage ditch 10, and the corrugated fin is divided into the first fin 51 on the windward side in the direction A of an air current and the second fin 52 on the leeward side. When the condensed water flowing at the inner face angle part 5c of the bend 5b of the windward first fin 51 reaches the space 53, the condensed water passage is interrupted, and condensed water stays in the vicinity of the leeward end of the first fin 51 and forms a liquid film G. Then, the condensed water in the vicinity of the leeward end can be discharged downward through the drainage ditch 10 of the tube 2 through a louver aperture 5e.

Title: Linear solenoid valve
Inventor: SUZUKI MIKIO
IPC: F16K31/06
Filed: 1992-12-08
Abstract: PURPOSE:To prevent the expansion of a weld strain range to a magnetic path, ensure freedom from a drop in magnetic flux density, allow a yoke or the like to be jointed with weld, and reduce manhours for manufacture by welding and jointing a spacer ring, a yoke and a valve sleeve along the periphery of edges in contact with one another. CONSTITUTION:A ring spacer 1 is formed to have both upper and lower ends 11 and 12 of small thickness, and the outer diameter thereof is formed to be small in step. On the other hand, a yoke 2 and a valve spring 3 are formed to be thin at the lower end 21 and upper end 31 opposite to each other, and the inner diameter thereof is enlarged in step. Then, both upper and lower ends 11 and 12 are pressed into the opposite lower end 21 and upper end 31, thereby positioning three members 1 to 3. Thereafter, the three members 1 to 3 are welded and jointed to one another at the outer contact sections 211 and 311 thereof. In this case, the outer contact sections 211 and 311 are substantially away from each inner contact section where a magnetic path passes. Thus, the range A of weld strain does not expand to the magnetic path. As a result, sufficient magnetic flux density can be maintained.

Title: Control device for construction machine
Inventor: SUZUKI MITSURU
IPC: F02D29/04
Filed: 1997-12-22
Abstract: PROBLEM TO BE SOLVED: To improve operability by controlling a working machine into the state of low target engine speed and high target engine output torque at the time of selecting a low speed driving work mode. SOLUTION: When normal operation of a first working mode is selected, an engine and a pump are controlled, so that engine speed becomes target engine speed NB(N'B), and engine output torque becomes target output torque P'S. When fine control of a second working mode is selected, engine speed becomes target engine speed NC(N'C) lower than the target engine speed NB(N'B), and engine output torque becomes target output toque P''L higher than the target output torque P'S. The speed decrease quantity of a working machine associated with the change of load pressure is therefore small compared to conventional constitution, and the whole are of a pump displacement variable area can be used, so that the hysteresis width of pump displacement control can be suppressed low ratio in the same way as normal work. Operability of a lever at the time of fine control can therefore be remarkably improved.
