Title: Wireless domestic telecommunication system for transmitting sounds and data
Inventor: BERKEN JAMES J
IPC: H04B7/24
Filed: 1990-11-29
Abstract: A wireless in-building telecommunications system for voice and data communications is disclosed having at least one node (101) arranged for linking to the PSTN (151) and at least one digital information source (153, 155, 157, 159) multiplicity of user modules (103) (UM's) linked to the node via a shared RF communications path (107). Each UM is coupled to a voice telephone instrument (127) and to one or more data terminals (165). The UM's communicate with the node by exchanging fast packets via the common RF path (107). The node also includes a fast-packet-switched mechanism controlled by a bandwidth allocating scheme to prevent collisions of packets as they are transmitted between the various units (101, 103) (nodes and/or user modules) that may be accessing the RF path (107). Also disclosed is a method for allocating the required bandwidth to each of the users of the common communications path in a wireless in-building telephone system. The invention provides for the combination of both voice and data in a single switch using a common packet structure. It allows for the dynamic allocation of bandwidth based on system loading. This includes not only bandwidth within the voice or data areas of the frame, but also between the voice and data portions. It also synchronizes the transfer of the data and the allocation of bus bandwidth.

Title: Magnetoresistance effect film, magnetic head, and magnetic recording and reproducing device
Inventor: HOSHINO KATSUMI
IPC: G11B5/39
Filed: 1997-01-08
Abstract: PROBLEM TO BE SOLVED: To improve the corrosion resistance of antiferromagnetic film without the drastic deterioration of a bonding magnetic field and thermal stability, by adding at least one kinds of transition metal elements or group IIIb, IVb element on the periodic table into an Mn-Ir antiferromagnetic alloy having an Ir compsn. in a specific range of multilayered magnetoresistance effect film laminated with magnetic film and antiferromagnetic film. SOLUTION: If about 5at.% additive elements Ti, Mo, Ru and Au are added to the Mn-Ir alloy having 8 to 55at.% Ir compsn., the bonding magnetic field and blocking temp. are slightly lowered but the corrosion resistance is improved. Namely, if no elements are added to the Mn-Ir alloy, the coupling magnetic field begins to be lowered when the holding time exceeds 300 hours. The lowering thereof begins to occur in the multilayered films formed by adding the Ti, Mo, Ru and Au to the Mn-Ir alloy when the holding time exceeds 450 to 500 hours. The similar effects are obtainable even if the other transition elements or the elements of group IIIb and IVb on periodic table are used.

Filed: 1989-01-06
Abstract: PURPOSE:To obtain the optical speech path which has no switch losses and with which the output level does not depend on the polarization state of incident light by subjecting plural LD optical amplifiers to optical cascade connection on both sides of optical matrix switches by intersecting the polarization directions to be mainly amplified orthogonally with each other. CONSTITUTION:The space divided optical exchange system connected with the optical matrix switches 1a, 1b and 1c, 1d on both sides of an optical inter-stage connection circuit 2 is constituted by connecting the respective input and output sides to the semiconductor laser type (LD) optical amplifiers 41, 42 via a single mode fiber (SMF) array 3a and SMDs 31, 3c and 32 when the speech path to connect the switches 1a, 1c is selected. These amplifiers 41, 42 are provided by intersecting the respectively polarization directions to be mainly amplified orthogonally with each other. The polarization state of the input light signal is preserved as it is in the switches 1a, 1c of this constitution and the switch operation is obtd. without depending on the polarization state of the input light signal as a whole. The level fluctuation of the output light is thus prevented. Since the immediate interaction of both the amplifiers on each other is prevented by the intervention of both the switches, the stable operation is assured while the gain is obtd.

Title: High-precise positioning method and device for work
Inventor: MORITA MASATOSHI
IPC: B23P19/00
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To reliably position a work in the desired position by reversely moving the work along the X direction before moving the work along the X direction and positioning it. SOLUTION: A top plate work 104 is pressed out by an adjusting bar in the direction P1 along the x direction by driving a position adjusting mechanism, and the top plate work 104 and a rib 104a are reliably struck to the end surface of a heater board 102. A stepping motor of a pressing mechanism is driven and moved in the plate spring direction P2 by only the prescribed distance, and the top plate work 104 is positioned to the heater board 102. Since the ascent gradient after striking is extremely large in comparison with the gradient of force by friction force, whether the rib 104a of the top plate work and the heater board 102 are struck to each other or not can be judged by detecting the gradient.
