Title: Communication method and device for the communication method
Inventor: KOTOBUKI KOKURIYOU
IPC: H04B1/707
Filed: 1995-09-08
Abstract: PROBLEM TO BE SOLVED: To improve the communication capacity by multiplying a quasi- orthogonal spread code with two systems of communication series with respect to one reception station and synthesizing the signals so as to facilitate error correction by a receiver side with a comparatively simple device. SOLUTION: A reception signal Ain1 is transferred from a 1st stage sample- and-hold circuit SH1 toward a sample-and-hold circuit SHm in the sample-and- hold circuits SH1 to SHm whose number corresponds to a spread rate. In this transfer process, the signal held in the sample-and-hold circuits SH1 to SHn is given to a couple of multipliers, where the signal is multiplied with spread codes PNI1 to PNIn, PNQ1 to PNQn specific to a reception station generated by the spread code generators of I, Q components. Then the results are multiplied by a multiplier X separately for the I, Q components and output signals Mi, Mq of the matched filter are outputted. Thus, the error correction by the receiver side is facilitated, the communication capacity is improved and one system of signal holding circuit in the reception station is enough and the extension of the circuit scale is slight.

Title: Electric motor and its manufacturing method
Inventor: SASAO MASAKI
IPC: H02K15/12
Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To make varnish sufficiently permiate the gaps of windings wound onto a rotor core in a short time by providing passing holes on coil brackets which cover rotor windings wound in the slots of a rotor core provided in the center of the magnetic field of a field core and which are inserted in the openings of the slots. SOLUTION: Because passing holes 11a are provided on coil brackets 11 positioned on the external circumference of rotor windings 4 provided inside a slot 12 of a rotor core 5, it is possible for varnish to permeate after the winding not only from the exposed parts of a coil 4a, 4b, both end parts in the axial direction of the rotor core 5 but also via the passing holes 11a of the coil brackets 11. As a result, varnish is able to sufficiently enter the gaps between windings wound in the inner part of the slot 12. This structure improves heat conduction between the windings, preventing the temperature rise of the rotor windings 4 to increase the efficacy of an electronic motor. Moreover, visual check is possible, and the reliability can be greatly improved.

Title: Inertia damper
Inventor: NAKANISHI MOTOYASU
IPC: F16F15/173
Filed: 1987-10-09
Abstract: PURPOSE:To suppress vibration on a shaft rapidly and to make it possible to isolate vibration in high accuracy by combining a shaft attaching body and an inertia body together through equipping with gel-like substance which is dispersed with particulates of ferroelectric ceramics in silicone resin which is made to be in penetration number 50-200, into gaps between projected faces of said two bodies. CONSTITUTION:A shaft attaching body 1 and an inertia body 2 are combined together through equipping with gel-like substance 3 dispersed with particulates of ferroelectric ceramics in silicone resin made to be in penetration number 50-200 into gaps between projected faces 131, 231. As a result of that, vibration generated on the shaft side brings deformation of the gel-like substance 3, but the deformation generates resistance in proportion to velocity difference between the shaft attaching body 1 and the inertia body 2 and restoring force due to annular difference for absorbing vibration energy to suppress vibration rapidly. While, deformation of the gel-like substance 3 itself can also be taken out as electric signal. therefore the signal can also be fed back to drive circuit, so vibration can be isolated in higher accuracy.
