A filter for removing contaminants from water. The filter has a first porous filter part formed by setting an active carbon in a high-molecular low-melt index polymeric binder. An inlet directs water to be filtered to the first porous filter part. An outlet directs water filtered by passage through the first porous filter part to a point of use.

A method of processing a photosensitive glass includes exposing. Photosensitive glass by radiation from a laser whose oscillation wavelength lies within the range of wavelengths of exposing light to which the glass responds. Then, the exposed portions 1c are thermally developed and etched. Since a laser beam propagates with a high rectilinearity, the front and rear surfaces of thick photosensitive glass can be exposed without producing dimensional errors. Therefore, the etching accuracy is improved. Especially, where the front and rear surfaces of photosensitive glass are etched, both surfaces can be processed so as to form the same shape in them accurately. In addition, because almost all the energy of the laser radiation is used for exposure of the photosensitive glass, the energy is not wasted and so the efficiency is high.

A time adjusting device for an electronic timepiece utilizes a manually rotatable mechanism which generates pulses corresponding in frequency and number with the speed and extent of rotation thereof. Each pulse which is generated is thereafter converted into a plurality of pulses. A manually actuatable switch applies either the normal periodic time pulses to a time counter or the plurality of pulses to the time counter upon actuation to adjust the time count therein.

Time adjusting device for electronic timepiece

Time adjusting means for electronic timepiece which detects change in the generation condition of pulses generated in response to a manual operation speed and generates a predetermined number of pulses in accordance with the detection output as the time-adjusting pulses. The time adjusting means enables a rapid time adjustment of an electronic timepiece at a high speed. When the manual operation speed exceeds a predetermined speed, the time adjusting means stops the time-adjusting pulse so as to prevent erroneous operation.
