Title: Upper thread transfer device of two-needle sewing machine
Inventor: YASUI HIDEO
IPC: D05B45/00
Filed: 1988-12-19
Abstract: PURPOSE:To eliminate an upper thread being pulled with motion of a cloth by supplying upper thread in a length greater than the distance of a bending point from a needle which varies through the cloth feeding action, and by adjusting the amount of supply of upper thread length. CONSTITUTION:Upper threads I1, I2 are fet to needles H1, H2 by an upper thread supply mechanism A at every action of transporting the cloth. A roller motor 2 is started when power is put on, and an upper thread supply roller 1 and an up and down collection roller 5 are in rotating condition at all times. During single needle sewing, the upper thread supply mechanism A supplies continuously the upper thread I2 even to the inner needle H1, and the upper thread I1 is prevented from being pulled unreasonably out of the stitch on the inner needle H2 side due to transport of the cloth under single needle sewing. When it is finished, an upper thread transfer mechanism performs collection of upper thread.

Title: Automatic travelling type electric vacuum cleaner
Inventor: YAMAGISHI TAKAHITO
IPC: A47L9/28
Filed: 1993-12-20
Abstract: PURPOSE:To make an effective automatic cleaning by moving the main body by the length of the suction port in the longitudinal direction when no dust collected from a floor nozzle remains and moving the main body in the width direction by the width of a suction port when an obstacle is sensed. CONSTITUTION:Dust is collected to a dust collecting room 4 by an electric fan 3 from a suction port 7 of a floor nozzle 8 under a main body 1. When a dust detecting means 37 detects that no dust remains, a travelling driving part 14 rotates a travelling wheel 15 and moves the main body 1 by the length of the suction port 7. The operation is repeated and the distance between the obstacle and the main body 1 is sensed 24 and when the contact of them is sensed 25, the main body 1 is moved by the length of the width in the width direction of the suction port 7. The steering to the side is performed by controlling the travelling driving part 14 by a steering motor 18 and a steering reduction gear 19. Then, the main body 1 is moved in the opposite direction by the length of the suction port 7 to collect dust. Thus, the remaining of dust and the re-cleaning can be prevented and the effetive automatic cleaning is performed.

Abstract: PROBLEM TO BE SOLVED: To quickly set a communication channel and to prevent the decline of service by improving a communication state inside a service area when the number of times of transmitting a communication channel setting request inside the service area of a base station becomes equal to or more than a prescribed value. SOLUTION: A retransmission timer is set so as to perform retransmission and a retransmission processing is performed until the upper limit number of times of the retransmission is reached. The retransmission processing is a processing performed when some kind of trouble is caused after mobile equipment 21 requests access to the base station 22 and a response from the base station 22 to the access is not returned. Then, in the case the number of times of the retransmission exceeds an upper limit value, the processing is interrupted and a standby state is attained until a call origination/position registration request is performed again. In this case, it is a measure taken so as to prevent an unrequired request processing from being performed when the mobile equipment 21 is on the outside of the service area and communication itself is impossible.
