An image processing apparatus, which displays an image corresponding to a synchronizing frequency change-image signal, which is obtained by changing a frequency of a synchronizing signal of an image signal, and an other image corresponding to an other image signal on a same display screen. The holding tank is located within a head of the cylinder, and has a single port serving for both ingress and egress of gasses to the combustion chamber. In the first and second embodiments, a flywheel is located for smoothing the power flow to the plunger drive arrangement, and in the third embodiment the flywheel is located for smoothing power flow to both the plunger drive arrangement and the auxiliary function drive arrangement. Movement of the second member causes flow of ink from the second ink supply. A concave surface below the snap bearing, which is retained by a pair of shoulders, allows the snap bearing to elastically deform during assembly of the connector to thereby reduce the risk of plastic deformation of the components while allowing significant improvements in overlap at the interface of the components. Also provided herein are vectors and host cells comprising those nucleic acid sequences, chimeric polypeptide molecules comprising the polypeptides of the present invention fused to heterologous polypeptide sequences, antibodies which bind to the polypeptides of the present invention and to methods for producing the polypeptides of the present invention.
