Filed: 1984-07-27
Abstract: PURPOSE:To listen a call tone in response to a preference of a user by providing a recording and reproducing circuit to a master set and transmitting a content in advance in the recording and reproducing circuit to a key telephone set. CONSTITUTION:The master set 2 is provided with an incoming circuit 3 detecting an incoming to a telephone line 1 and the recording and reproducing circuit 4. A recording button of the key telephone set 5 is depressed in advance and an optional voice is recorded to the circuit 4 as a call tone via a talking circuit from a transmitter 6. The optional voice is a preferred and familiar voice such as sound of a steam engine, bird song, music or human voice. When an incoming call comes to the line 1, the circuit 3 in the set 2 detects it to start the circuit 4. Since the circuit 4 reproduces and transmits the recorded content to the telephone set 5, it is outputted from a speaker 7 incorporated in the telephone set 5 and the user of the key telephone set can recognize the incoming call.

Title: Semiconductor laser module device
Inventor: SARUWATARI MASATOSHI
IPC: G02B6/42
Filed: 1980-11-10
Abstract: PURPOSE:To eliminate a reflection in a coupling region between an optical fiber and a laser light by a method wherein a window thickness of a laser package is preferred to be 1/4 of a wave length and its optical axis is slanted to show an angle of 45 deg. in a perpendicular plane to a polarizing direction of the light from a laser chip. CONSTITUTION:A laser light 23 is a linear polarized wave parallel to a junction plane. A polarizing direction is taken as x axis, and a plate 24 having a thickness of 1/4 of a wave length is placed on it. Because an optical axis 25 is slanted to show 45 deg. to the x axis, the light is reflected at a surface 27 through being converted into a clockwise circular polarized light 26, and it is changed by second passing through the plate 24 having a thickness of 1/4 of a wave length, into a linear polarized wave 29 which has perpendicular relation to the initial linear polarized light. Accordingly when a plate having a thickness of 1/4 of a wave length is inserted at the rear stage of a laser through preferring an axial direction, as easy separation of a reflected light returning to the laser can be attained, and a coupling efficiency is not expended as a sacrifice. In an embodiment, a hermetic window 17 is built of a plate having thickness of 1/4 of a wave length made of sapphire and is fixed by soldering so that an optical axis 25 of sapphire may be taken to be slanted at 45 deg. referring to an active layer of the laser 15 when hermetically sealed. In this constitution reflection from an incident surface of the fiber 18 is very low and is made lower with an additional utilization of anti-reflection film.

Title: Method for reducing load of moving-magnet linear motor

Filed: 1994-06-15
Abstract: PURPOSE:To easily and effectively reduce the load on a linear motor by making an upward magnetic force and downward dead load of a magnet act to the magnet by fitting a magnetic circuit forming a yoke to the casing of a moving section above the magnet. CONSTITUTION:At the time of sliding a casing 5 in the axial direction together with a shaft 13 by applying an upward or downward magnetic force to a magnet 16 by making an electric current to flow to a winding coil 3, a force which moves the magnet 16 upward is generated by bringing the magnetic circuit B of a linear motor to a position above the magnet 16. In addition, since the dead loads of the magnet 16, casing 15, and shaft 13 act as forces which move the magnet 16 downward, the upward magnetic force and downward dead loads act on the magnet 16. Therefore, the size and weight of the linear motor can be reduced, because the load of the motor can be reduced and the current value of the motor at the lifting time and standstill time can be reduced.

Title: Electrophotographic direct drawing type planographic printing plate
Inventor: MORI KENICHI
IPC: B41N1/14
Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To obtain an electrophotographic direct drawing type planographic printing plate which does not require etching processing and is excellent in printing durability by making an image receptive layer incorporate water absorptive polymer particles and hydrophobic resin. SOLUTION: The image receptive layer is principally composed of the water absorptive polymer and the hydrophobic resin. When an image by toner is formed by such constitution, the contact of the image receptive layer with the toner is made excellent by the hydrophobia resin on the surface and it is made excellent in the printing durability. In the case of offset printing, the water absorptive polymer particle absorbs damping liquid and swells, so that the surface is made hydrophilic, and then a non-image part is not soiled. In such a case, material is not restricted as a supporting body particularly, but plastic film and paper are desirable. The particle is not restricted as the water absorptive polymer particle particularly if the particle can absorb water several- ten times to hundreds times as heavy as itself in weight.
