Title: Thread control in automatic thread tension sewing machine
Inventor: HANIYU SUSUMU
IPC: D05B45/00
Filed: 1987-06-26
Abstract: PURPOSE: To prevent fluctuation generated by the difference of the elongation characteristics of threads by turning a needle thread pressurizing device to a high clamping pressure so as to generate elongation in a needle thread between a needle and the needle thread pressurizing device at the time of the pull-in phase of the needle thread and controlling it to a low clamping pressure at the time of a thread supply phase to a stitch.  
     CONSTITUTION: The needle thread 5 pulled out from a needle thread barrel 47 is guided through a thread guide 48 to a part between a pair of thread clamping plates 36a and 36b of a first needle thread pressurizing device 36, guided to the part between the thread clamping plates 41 and 42 of a second needle thread pressurizing device 39, then hooked to a balance 34 and led to a needle hole. The first needle thread pressurizing device 36 supplies fixed clamping force T 1  at all times during a sewing cycle and the second needle thread pressurizing device 39 supplies strong clamping force T 2  by the pressurization of a spring 43 from the phase of roughly eliminating the elongation of the needle thread by the lowering of the balance 34 to the phase reaching a dead center on the balance. The elongation is generated by supplying the high clamping pressure at the time of pulling out the thread from the barrel, a state with less elongation is attained by turning it low-in the clamping pressure at the time of supplying the thread, the thread is supplied for the difference and the variation of the needle and bobbin thread entangling position of the stitch is prevented.

Title: Disk type brushless motor with preferable efficiency of superposed armature coil type
Inventor: HIRANO NORIMITSU
IPC: H02K3/04
Filed: 1983-08-29
Abstract: PURPOSE:To obtain a large torque, to reduce a torque ripple and to improve the performance of a brushless motor by filling a conductor unit which contributes to a generated torque of an armature coil of one set in cavity in a frame of the armature coil of the other set as a stator armature. CONSTITUTION:Since armature coils 1-1,...,1-6 are formed by bending the conductor units 1c, 1d of the inner and outer peripheries which do not contribute to the generated torque, conductor units 1a, 1b which contribute to the generated torque can be sequentially contained in the cavity in a frame of the armature coil. Accordingly, even if six armature coils 1-1,...,1-6 are superposed at an equal interval, the radial conductor units 1a, 1b which contribute to the generated torque can be arranged so as not to be superposed planely uniformly. Thus, since a stator armature 28 is not superposed in double at the armature coils, an air gap is not increased, and the coils 1-1,...,1-6 are provided in number of twice of those of the conventional one. Accordingly, large rotary torque of substantially twice can be obtained, a torque ripple can be smoothed to approx. 1/2, and a disk type brushless fan motor which has extremely good performance can be readily obtained.

Title: Thin film for inas hall element
Inventor: SHIBAZAKI ICHIRO
IPC: H01L43/14
Filed: 1990-06-18
Abstract: PURPOSE:To obtain a Hall element having characteristic in which a resistance value is not lowered together with a temperature by providing an electron mobility structure of two layers of low and high electron mobility parts of predetermined thickness, and doping doner impurity at the high mobility part in a predetermined range of carrier concentration to form an InAs thin film. CONSTITUTION:A material for an InAs Hall element has a thin film of two-layer structure of a low electron mobility part 21 near a boundary of a substrate 1 and a high electron mobility part 22 separately from the boundary. As impurity atoms, those which act as doner impurity 3 with InAs is generally desirable, such as Si, S, Ge, etc. Doping amount is necessarily at least 4X10<16> pieces/cm<3> or more as carrier concentration, and the upper limit of the carrier concentration is 8X10<16> pieces/cm<3> due to the limit of doping amount of the impurity atoms. In a thin film of 1.4mum or less to be used desirably as a Hall element, Si, S, Ge are particularly desirable as dopant. Thus, a phenomenon in which a resistance value is lowered together with a temperature rise is eliminated.
