Title: Method for manufacturing stator of flat-type motor
Inventor: KAMIYA YUTAKA
IPC: H02K15/12
Filed: 1977-09-19
Abstract: PURPOSE: To improve undesirable influence of ununiform temperature distribution in coil etc., by injecting insulating resin into the air-gap formed between the windding-core and the flange and into the clearance formed by tearing off of the insulating resin from the flange and hardening the same.  
     CONSTITUTION: One end surface of winding-core 2 is fixed to the flange 1 and the slot 3 provided on the other end is caused to receive coil 4. Then, insulating resin 5 is injected to enclose the end portion of the coil and to bond it to the flange surface, and hardened. The flange, bent by hardening contraction of the insulating resin bonded to the flange, is torn off from the resin 5, and very small clearance 10, 11 produced by the tearing off is injected with insulating resin 12, which is then hardened. This injection of resin 12 prevents the deterioration of cooling effect due to clearance produced between the lower end of the winding-core 2 and the flange 1 by the deformation of resin 5 when it is hardened, and also prevents ununiform temperature distribution caused by exfoliation of the bonded surface between the resin and the flange

Title: Notch filter adjusting method for positioning control system
Inventor: MIZOSHITA YOSHIBUMI
IPC: H02P29/00
Filed: 1986-05-16
Abstract: PURPOSE:To automatically adjust a frequency of a notch filter by generating a disturbance noise signal, obtaining a positioning error signal against a position signal from a controlled system, and also, varying a frequency of the notch filter, and measuring the positioning error signal. CONSTITUTION:A suppression effect by a suppression frequency which has been set to a notch filter 2b is measured by injecting the disturbance noise NS to an actual positioning control system. That is, when the frequency which has been set to the notch filter 2b coincides with a resonance frequency of a controlled system 3b, a resonance frequency component of a position error (er) is suppressed, and the controlled system 3b does not resonate, therefore, an amplitude or an effective value of the position error (er) becomes small. Accordingly, when the frequency of the notch filter 2b is varied by injecting the disturbance noise NS in an operation zone, the resonance frequency of the controlled system 3b becomes equal to the set frequency of the notch filter 2b at the time of the minimum value of the position error (er). In this way, an optimum suppression frequency can be set to the notch filter 2b.

Title: Hollow yarn membrane with fins for dialysis and manufacturing method thereof
Inventor: OMICHI TAKAHIRO
IPC: B01D71/12
Filed: 1996-04-10
Abstract: PROBLEM TO BE SOLVED: To prevent reduction of the mass transmission coefficient by membrane thickness increase at fin attaching parts, by forming a dense layer with specific values of thickness and average yarn radius on the outer layer part of the whole parts of a hollow yarn membrane and making the average porosity of the whole membrane to be a specified %. SOLUTION: The membrane part of hollow yarn membrane with fins is composed of two layers of a dense skin layer to manage the porosity of the hollow yarn membrane and an inner layer with a coarse porous structure. The skin layer with 30-1,000nm of thickness and 5-25nm of the average pore radius forms the outer layer of the whole hollow yarn membrane. The average porosity of the whole membrane including the skin layer and the porous inner layer is to be in a range of 60-85%. If the thickness of the skin layer is lower than 30nm, a membrane defect is easily generated to cause useful protein to be easily leaked. If the thickness exeeds 1,000nm, the transmission resistance becomes too large. If the average radius is under 5nm, harmful low molecular weight protein in blood becomes hard to be removed. If the average radius exeeds 15nm, leak of useful protein in blood becomes remarkable.
