Title: Exhaust emission control device for internal combustion engine
Inventor: HIROTA SHINYA
IPC: F01N3/18
Filed: 1992-12-11
Abstract: PURPOSE:To shorten the time required for regeneration by reducing consumption of a reducing agent when NOx absorbent is regenerated. CONSTITUTION:When NOx absorbent is regenerated by supplying a reducing agent to a container from a reducing agent supply quantity supply device 4 after inflow of exhaust gas to the container 3 to house the NOx absorbent 1 is cut off, an air current is generated to carry the reducing agent through the NOx absorbent. Since a high concentration reducing agent layer passes through the NOx absorbent while being carried on the carrying air current, respective parts of the NOx absorbent are generated successivly as the reducing agent layer passes, so that regeneration is carried out efficiently in a short time by a small quantity of reducing agent.

Filed: 1990-11-30
Abstract: PURPOSE:To smoothly conduct charge to a lead accumulator left over discharged by alternately conducting the electrification in the reversed direction and the application of a high voltage in the positive direction once or more when the charge is started, and the charged current does not reach a determined magnitude, and thereafter, conducting a general charge. CONSTITUTION:When charge is started, and the charged current does not reach a determined magnitude, a high voltage in positive direction is applied to a lead accumulator addition to the sending of a current in the reversed direction. For example, to a sealed type lead of 4Ah-4V type (internal resistance 1600OMEGA) left over discharged, at the point of time when the current in the reversed direction is sent for 30 minutes (1.2A limitation, $....-2.45V/cell limitation), the charge (1.2A limitation, 15V/cell limitation) is conducted for 30 minutes at a high voltage. Thus, the current can be sent against a resistant film in passive state generated while the battery is left over discharged, and the charging property can be ensured.

Abstract: PURPOSE:To enable high performance of a boiler by specifying L/D and arraying water tubes in squares when a pitch in the direction of a gas flow of a water tube group is made L and the outer diameter of the water tubes is D. CONSTITUTION:In a boiler having a water tube group in a furnace or a convection heat transfer part, when a pitch in the direction of a gas flow of the water tube group is made Lmm and the outer diameter of a water tube 3 is Dmm, the water tube group is arrayed in squares as 1.8<L/D<2.5.

Filed: 1994-12-17
Abstract: PURPOSE: To make a ring convenient to put on one's finger while preventing the slipping-off of the ring by forming the inner diameter part of an annular part into an oval shape wherein a decorative part is positioned on a long axis. CONSTITUTION: The inner diameter part 3 of an annular part 1 is formed into an oval shape wherein a decorative part 2 is positioned on a long axis toward the decorative part 2. The inner diameter part 3 of the annular part 1 of a ring is allowed to coincide with the shape of a second joint, that is, the oval shape. Therefore, when the ring is put on, the ring is put on one's finger in such a state that the inner diameter part 3 of the annular part 1 of the ring is made parallel to a finger row, that is, the decorative part 2 of the ring is rotated by 90 deg. from a normal position and the decorative part 2 is rotated to the back of the hand for the first time when the inner diameter part passes the second joint part to complete the putting-on of the ring.  Since the inner diameter part 3 of the annular part 1 of the ring is allowed to coincide with the shape of the joint of a finger, the ring can be put on smoothly. Since the putting-on of the ring is completed by rotating the decorative part by 90 deg. after putting-on, the ring becomes hard to slip off from the joint part and the slipping- off thereof is reduced.
