A diaphragm-type carburetor includes a fuel well communicating with a lower end of a fuel nozzle, a constant-pressure fuel chamber communicating with the fuel well through an outlet bore, and a fuel pump incorporated in fuel passages defined between an inlet bore of the constant-pressure fuel chamber and a fuel tank. A fuel introduction control valve controls the introduction of fuel into the constant-pressure fuel chamber. The fuel introduction control valve includes a valve seat member which communicates at its lower end with the fuel well through a bypass passage extending above the constant-pressure fuel chamber. Thus, when fuel vapor is introduced into the constant-pressure fuel chamber, it immediately passes towards the fuel nozzle, whereby the extreme reduction in air-fuel ratio of a fuel-air mixture can be avoided.

A laser treatment apparatus which performs a medical or surgical treatment using laser-beam irradiation, The apparatus has a solid-state laser medium for obtaining a laser beam and an excitation light source for exciting the solid-state laser medium. The apparatus further has a first optical system having a Q-switch which emits light oscillated by the solid-state laser medium as a pulse wave laser beam, and a second optical system which emits the light oscillated by the solid-state laser medium as a continuous wave laser beam. An optical path for the light oscillated by the solid-state laser medium is switched to one of optical paths of the first and second optical systems. With this apparatus, plural oscillation modes and wavelengths can be switched over in accordance with the treatment object, and the load on the user is reduced.

Disclosed is an engine fuel supply apparatus which can be made smaller in size and in which the amount of fuel in an air-fuel mixture can be increased with a fast response in correspondence with the operation of a throttle valve when the engine is accelerated rapidly. The fuel supply apparatus is provided with a fuel booster pump. A portion of an air-fuel mixture is introduced into a negative-pressure chamber of the fuel booster pump via a negative-pressure chamber channel, and the fuel booster pump is actuated. The actuation forces air in a pump chamber to flow into a pressure chamber, and fuel in a fuel storage chamber is temporarily supplied to a carburetor.

An image processing apparatus includes a receiving unit, an image-element group determining unit and a shape changing unit. The receiving unit receives (i) a command to form a blank space and (ii) information specifying a position where the blank space is to be formed in a drawing space for displaying a drawn image. The image-element group determining unit determines, as an image-element group, image elements having a predetermined relation with each other and being drawn in the drawing space. The shape changing unit performs a shape changing process collectively for the image elements of image-element group. The shape changing process includes at least one of (i) a process of moving image elements of the image-element group so as to move the image-element group away from the specified position where the blank space is to be formed, and (ii) a process of reducing the image elements of the image-element group
