A respirator assembly is described, which includes a respirator shell defining an air inlet opening, an air inlet conduit positionable within the air inlet opening, and an outer device configured to fit over the air inlet conduit and sandwich a portion of the respirator shell between the air inlet conduit and outer device. The image forming apparatus carries out image formation by primarily transferring an image electrophotographically formed on an image carrier onto the rotatably driven intermediate transfer member, and then secondarily transferring the images on the intermediate transfer member onto a recording medium. The instruction description is retrieved as accompanied by the associated behavior function description from the database. The front steering includes an upright pivot shaft connected at an upper end thereof to a mating cavity or aperture formed on a front hood of said car body which allows a further reduction in profile height of the hood of the toy car. Periodically, the process of testing the frequency versus force can be reviewed and the operating frequency adjusted. Encapsulants are formed in the cavities to seal the light emitting chips.
