A coordinate input and detection device includes a touch panel, light emitting units, a reflective member, intensity distribution detection units, a coordinate detection unit, and filters. The processing apparatus has a magnetometer-assisted mode of operation in which measurements from the magnetometer are used to estimate the navigational state and an alternate mode of operation in which the navigational state of the device is estimated without measurements from the magnetometer. Example of the poorly water-soluble polymer include a polymer having a solubility of 1. The refractory system may also include columnar cavities. For clamping of the tool a split chuck is provided which is clamped on the retaining section by the securing element in the clamped position and is connected with the retaining section in form-locking engagement. The appliance also includes a pressure reducing device arranged within an evaporator-condenser refrigerant circuit, and a valve system for directing or restricting refrigerant flow through the device.
