The present invention provides a gas filling-type ball for sports which has excellent non-slip property and sufficient mechanical strength such as surface abrasion resistance, and which can be particularly suitably used in a field of a material for a ball such as a basketball, American football, or rugby ball. The emergency eyewash station includes a reservoir containing an eyewash fluid and a mechanism for dispensing the eyewash fluid from the reservoir to wash an injured person’s eyes. The converter further comprises a regulator circuit comprising a regulator circuit feedback input and a regulator circuit output, the regulator circuit feedback input coupled to the feedback output and the regulator circuit output coupled to the energy storage element input, the regulator circuit regulating the input of the first power level to the energy storage element input. The sampling rate of the ordinary AD-C is equivalently enhanced without installing an additional AD-C. The local oscillator signal to the mixer that may downconvert the RF signal to a VLIF signal may be an output of a programmable local oscillator, and may be one of a plurality of frequencies.
