IPC: E01F8/00
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To reduce the size of pressure fluctuation by arraning pressure reduction walls projecting in a direction to be parallel with or cross a track at specified intervals along the truck. SOLUTION: In installing pressure reduction walls 1 at specified intervals as an installation pattern of the walls 1 in a direction to cross at right angles with a track from a side wall 2 on a side of the track, there is a case that they are installed slantly and a case that they are installed to cross in the perpendicular and horizontal directions. The height of the walls 1 is set to a level that does not exceed 2.5 m and the projecting size thereof to the track side is made close to the track side as much as possible, thereby enhancing the effect. The walls 1 disturb the field of air flow generating around a train passing through the air in the side of the train. As a result, the size of pressure field in a tip of the train is reduced. Accodingly, reduction of pressure fluctuation as well as prevention of deterioration in the circumferential view along the track and the view from the window of the train are achieved.

Abstract: PURPOSE:To assure a better finished state of grill cooking by a method wherein means for selecting a grill cooking operation where a shutter is opened in the way of cooking operation and a grill cooking operation where the shutter is not opened at all is provided. CONSTITUTION:When an operation I is selected by a changing-over means 20, for example, a heater 13 is energized (ON) just after a cooking is started and a shutter is kept closed. As an energization of the heater 13 is continued and when a temperature within a storing space becomes a certain level Ts, a shutter 17 is opened and the heater 13 is kept energized. After this operation, a temperature level of Tc higher than Ts is set and the storing space 12 is controlled for its temperature at the level. This operation I may provide a sufficient scorch at a surface of a food such as a beef steak. It is suitable for a food having a rare state within it. A selection of an operation II causes an energization of the heater 13 to be continued while the shutter 17 is being closed during a cooking time. When the temperature reaches a certain temperature level Tc, the energization is temporarily stopped and subsequently a temperature within the storing space 12 is controlled at the level Tc, the operation II is suitable for a food of which surface is scorched to some extent such as a chicken leg and its inside part is sufficiently heated.

Abstract: PROBLEM TO BE SOLVED: To provide a soldering apparatus that makes the the temperature drop of the melted solder constant to suppress defects in soldering process. SOLUTION: Solder reserved in a tank 11 is heated and melted by a heater. A moving part 15 transfers the solder in a tank 11.

The discharging wall of nozzle 16 is coated with Teflon (R) resin in thickness of about 2 to 3 μm to form a Teflon resin film 17. Therefore, fused solder is discharged to the leg of an electronic component 21 arranged on the substrate 20, while making contact with the Teflon resin film 17 formed at the discharging wall of the nozzle part 16. The Teflon resin is a material, having poor affinity with the solder, the solder chip no longer adheres to the discharging wall of the nozzle part 16.

Abstract: PURPOSE:To allow the device to maintain an excellent offset preventive capacity with respect to a large quantity of passing paper, by interposing and installing an inner layer, a surface layer and an intermediate layer to an oil impregnated layer so that oil is spread uniformly over the whole surface of a fixing roller. CONSTITUTION:Oil A whose viscosity is dropped by being subjected to heating of a fixing roller K1 passes through a through-hole 12 and infiltrated and diffused toward a surface layer 23 of an oil impregnated layer 2, and first of all, diffused while being controlled as to its flow rate in a fiber layer for forming an inner layer 21. Also, an intermediate layer 22 formed by sponge rubber runs along a boundary surface 3 of the inner layer 21 and the intermediate layer 22, and extends in the direction made by its surface. The intermediate layer 22 is brought into contact with the surface layer 23 consisting of a fiber layer whose permeability is safisfactory and whose density is low, therefore, in the intermediate layer 22, oil is transfer to the surface layer 23, and simultaneously, diffused in the direction for running along the layer in the surface layer 23. As a result, oil is distributed uniformly in the vicinity of the surface of the surface layer 23 which is pressed against the roller K1, and supplied evenly to the roller surface of the roller K1. In such a way, the offset preventive capacity can be maintained.
