This disclosure provides a negative-working resist composition comprising a calix resorcinarene derivative of specific structure, an acid generator which directly or indirectly generates an acid when exposed to an active energy ray having a wavelength of 248 nm or less, and a cross-linking agent. The system comprises a pair of elastic conveyor belts guided by certain cylindrical bodies, which can be aided by some freely rotating rods, with one of the cylindrical bodies acting on each one of the elastic belts as a drive element for transmitting independent movement to them. The separation unit takes an index value and an alpha value separately out of the texel value in the index form, and provides the index value to a lookup table reference unit and the alpha value to a synthesizing unit. The controllable frequency divider circuit provides any division factor among a set of division factors in which for any division factor a ratio between that division factor and a lower division factor closest thereto, if existing, does not exceed 1. When the temperature of the heating section or between the heating section and the condensate recovering unit is dropped by a predetermined value, steam is supplied from the steam supply pipe to the inlet of the steam ejector, and gas in the heating section is sucked into the suction chamber of the steam ejector. The elastic device is configured for providing an elastic force to open the battery cover relative to the back cover.
