A position of an inner surface of a panel ( ) is measured with the panel being held, and a position of a main surface of a color selection electrode ( ) is measured with a color selection electrode frame ( ) being held, so that the measured positional data provide a measured value corresponding to a spacing between the panel inner surface and the main surface of the color selection electrode. In a state that the engaging holes of the supporting members are engaged with dummy pins ( ) arranged in a predetermined positional relationship to the panel pins ( ) on the condition that the panel is held, the position of the main surface of the color selection electrode is adjusted with respect to engaging holes on the basis of the predetermined positional relationship and the measured value, and supporting members are fixed by welding to the color selection electrode frame.

Method of assembling color crt and assembling device

A first loop antenna apparatus is disclosed which includes an open loop antenna portion and an inductor having a predetermined inductance and first and second ends connected to first and second intermediate points of the open loop antenna portion. The inductance of the first loop antenna apparatus is decreased because the inductor is connected in parallel, so that an opening area (antenna gain) is increased at the same resonant condition. A second loop antenna apparatus is also disclosed which includes an open loop antenna portion, a first inductor having a predetermined inductance, one end of the first inductor being connected to first intermediate point of the open loop antenna portion, a second inductor having the predetermined inductance, one end of the second inductor being connected to a second intermediate point of the open loop antenna portion, and a capacitor having a predetermined capacitance, connected the other ends of the first and second inductors. Similarly, the inductance of the second loop antenna apparatus is decreased because the inductors and the capacitor is connected in parallel, so that an opening area (antenna gain) is increased at the same resonant condition.

Loop antenna

A self-priming chemical pump which comprises: a pump portion including at least an impeller and a shaft supporting the impeller; a self-priming mechanism portion including a self-priming chamber which is provided in the discharge side of a vortex chamber of the impeller so as to communicate with a discharge opening, and a suction chamber which is provided in the suction side of the vortex chamber of the impeller so as to communicate with a suction opening; a seal wall which is provided in the vicinity of the discharge side of the vortex chamber to form a slight gap along the outer circumference of the impeller; and a circulation hole which is provided in the self-priming chamber so as to be located inside the outer circumference of the impeller.
