摘要： PROBLEM TO BE SOLVED: To obtain an automatic speech connector applicable to various telephone service networks such as public line-leased line-public line connection telephone network, Internet telephone network and callback telephone network. SOLUTION: A telephone adapter 103 is provided between an analog telephone set 108 and a line network 101. The telephone adaptor 103 stores a parameter corresponding to various communication networks and the user makes a telephone call through the least cost routing by means of abbreviation dialing. Each telephone adapter 103 is centrally managed by a management center 104. Furthermore, the telephone adapter 103 can receive various services meeting social needs from a service center 105.

摘要： PROBLEM TO BE SOLVED: To provide a method for readily pasteurizing or exterminating bacteria and pests against seeds without using chemicals in a short time by irradiating laser beam to the seeds including the seeds for agriculture and horticulture. SOLUTION: A laser beam is directly or indirectly irradiated to seeds including the seeds for agriculture and horticulture in the method for pasteurizing or exterminating bacterium and pest against the seeds. When the irradiation is carried out, the seeds as the irradiation objects is preferably moved while changing the faces facing to the incident direction of the laser beam. The laser beam is preferably allowed to be freely reflected and projected to the seeds as the irradiation objects.

摘要： PROBLEM TO BE SOLVED: To make an equipment small in size and thin in thickness by inserting a semiconductor equivalent circuit to subscriber lines at a reference point and a U point with respect to an ISDN(integrated services digital network) line. SOLUTION: It is necessary to efficiently send a high frequency signal to a DSU(digital service unit) 12 through a high frequency transformer. At a U point, it is necessary that a DC component is cut by setting a signal component to a high impedance to allow only a high frequency signal component to pass through and that lines L1 and L2 are short-circuited for a test loop 2A from an exchange at the time of originating a call from a terminal. In this case, the resistance value is set to

摘要： PURPOSE:To enable beautiful welding without generating strain even in a thin metal material by melting and joining objects to be worked by irradiating then with a laser beam, and quickly quenching a weld zone by ejecting water. CONSTITUTION:Objects 1 and 2 to be worked, are melted and joined by irradiating the objects with a laser beam 5 by a NC to the metal objects 1 and 2 to be worked. Then, the weld place 10 of the works 1 and 2, is quenched by quickly ejecting water or mist from the ejector 9 of a hose 7 toward the weld place 10 of the works 1 and 2 to be worked. When irradiating the objects with a laser beam, gaseous argon or gaseous nitrogen is added as assist gas. Water or mist is ejected by the control with NC and sensing ultrasonic vibration by welding work. Consequently, a very wide range such as a stainless steel pool, a large type water bath, the tank body of a railway vehicle, etc., in addition to the outer panel and the roof material of a building, can be covered by this welding.

摘要： PURPOSE:To enable transportation to a jobsite in the condition of a pipe shape without perfectly cutting-of and to facilitate the handling thereof by intermittently cutting the pipe while remaining bridge parts at the time of cutting by no- contact machining with laser beam. CONSTITUTION:At the time of cutting the pipe 1 by irradiation of the laser beam, the pipe material 1 cut while remaining the bridge parts 3 on the cutting 2 line in the fixed interval, is turned over at 180 deg. angle and even if the opposite side at 180 deg. turning is cut in the same way, this material can be transported to the jobsite in pipe-shape state as it is. In the jobsite, by hammering the edge part of the pipe material 1, the pipe material is cracked at the bridge parts 3 an the semi-circular pipes 1a, 1b can be obtd. by slippage. Further, in the case of cutting only one side of the pipe material 1 such as large diameter pipe, thick pipe, or bent pipe, the bridge part 3 is cut with a hand saw, etc., from the space part machined at the faced end part of the cutting part 2. Further, since this machining is the non-contact type with the laser beam, the breakage of the edge and the damage of the pipe material 1 caused by the biting of the edge into the pipe, are eliminated.
