Abstract: PURPOSE: An extension number announcement system using a telephone and a method thereof are provided to enable even an old and feeble person or an orally handicapped person to easily select an extension number by providing an announcement message in voice or character. CONSTITUTION: If a telephone is off the hook by a user and a telephone number is input, a DTMF signal(or a tone signal) is generated and output to a private branch exchange(S10). The telephone outputs a ring back tone signal to the user(S12). If the private branch exchange detects the DTMF signal received from the telephone(S40), the private branch exchange draws out voice and character announcement data from voice and character announcement memories(S42). The private branch exchange transmits the drawn voice and character announcement data to the telephone(S44). The telephone separates voice and character announcement messages(S14), outputs the voice announcement message to a speaker(S16), and stores the character announcement message at a memory(S18). The telephone divides the character announcement message to be appropriated for the size of a LCD and outputs the divided character announcement message to the LCD(S20). If the user inputs a specific extension number, the telephone transmits the DTMF signal of the corresponding extension number(S22). The private branch exchanger received the corresponding extension number sets up a call path with an extension telephone having the corresponding extension number(S46).

Abstract: The rotary motion of an input shaft is firstly altered into a controllable rotational oscillation of an intermediate member and subsequently, by means of an overrunning clutch mechanism, this oscillation is transformed into one way impulses towards output shafts which drive the loads. The connecting mechanism between the input shaft and the intermediate member controls, according to its condition, the amplitude of the angular oscillation of the intermediate member within a minimun/maximum, defining the transmission ratio. Inherent drawbacks like the strong impact loads are eliminated as long as the output shafts drive the loads through proper elastic connections while additional overrunning clutches, secured to the casing, prevent the reverse motion of the output shafts.

Abstract: A film of a coating material is produced on a substrate (22) by a pulsed laser deposition method in which the material that forms the coating material is first combined with a matrix material to form a target (16). The target (16) is then exposed to a source of laser energy (12) to desorb the matrix material from the target (16) and lift the coating material from the surface of the target (16). The target (16) and the substrate (22) are oriented with respect to each other so that the lifted coating material is deposited as a film upon said substrate (22). The matrix material is selected to have the property of being more volatile than the coating material and less likely than the coating material to adhere to the substrate (22). The matrix material is further selected as having the property such that when the target (16) is exposed to a source of laser energy (12), the matrix material desorbs from the target (16) and lifts the coating material from the surface of the target (16). In another aspect of the invention, a method of making an improved chemical or biochemical sensing device that includes a chemoselective or bioselective coating on a substrate (22) is carried out by coating the substrate (22) by pulsed laser deposition.
