Abstract: A rotational difference between the speed corresponding to a cylinder at a combustion stroke and the speed corresponding to the cylinder at a previous combustion is calculated. Then, a corrected value is derived from averaging all the rotational differences up to the present combustion stroke. A corrected rotational difference is calculated by subtracting the corrected value from the rotational difference. The misfire judgment level is calculated and set with an interpolated calculation by referring to the map that has the parameters of engine speed and fuel injection pulse width. The level is then compared with the corrected rotational difference. If the corrected rotational difference is larger than the misfire judgement level, and if the corrected rotational difference at the previous combustion stroke is smaller than the level that has a minus value, it can be accurately judged that the cylinder at the previous combustion stroke is in a condition of misfire.

Abstract: The invention relates to an inhaler for products such as medicaments, and particularly to an inhaler for transferring to a patient a metered dose of product contained in a pressurized dispensing container. The inhaler includes a housing adapted to receive a pressurized dispensing container, a mouthpiece, duct means for connecting an outlet of the container with the mouthpiece and air inlet means for allowing air into the inhaler for when a user applies suction to the mouthpiece. The housing also comprises a mechanical break-up component located in the duct means. The component breaks up the product as it passes along the duct means, before mixing with the air flow to effect atomization of the product. The duct means includes a chamber for receiving the mechanical break-up component, the chamber having an end wall providing a barrier between the chamber and the mouthpiece to prevent the mechanical break-up component from entering the mouthpiece.

Abstract: A control unit for a hot and cold water mixer that includes one cartridge, one movable disc, one fixed disc, and one valve seat. Within the structure, the first and second openings and the third shell shape opening of the fixed disc will provide the maximum area of water flow in conjunction with the enlarged area of the mixing chamber of the movable disc. The unit will increase the water flow of the valve and will facilitate the transporting capability of a more uniform temperature water. In addition, the cartridge structure may, for any purposes, assemble various connecting pipe lengths or specifications to the valve seat and may form the desired specification as well as reduces the production cost of cartridge molds.

A nose portion is used to combine the base and the fixing base to form an integral body that is separable from each other. An open end of the transparent box is connected with the rubber plug base. Accordingly, the base may be easily separated from the fixing base so that a card may also be inserted into or removed from the open end of the transparent box, thus the ball appearance is achieved.

Abstract: An improved polarity fuse plug. The plug includes an outer shell, an inner plug, 2 electric conductors, a concave shaped butterfly plate and a water proof chip. The outer shell is a flat stand and the inner plug holds each electric conductor separately. One of the electric conductors is connected to the fuse and the end of the other electric conductor is connected to the power cable. There is a concave shaped flume on the side of the fuse box and inside of the box has the concave shaped butterfly plate plugged onto it. The end of the concave shaped butterfly plate is connected to the power cable so as to avoid exposing the power cable when the fuse box is opened.
