Title: Automatically cancelling device of turn signal lamp
Inventor: MIYAMARU YUKIO
IPC: B60Q1/40
Filed: 1981-06-02
Abstract: PURPOSE:To automatically cancel a turn signal lamp at adequate timing, in an autobicycle, by applying the method of detecting a steering angle at a low speed while utilizing a timer circuit at a high speed and outputting a cancellation signal. CONSTITUTION:In case of low and medium speeds, a signal of a handle steering angle sensor 1 is processed by a signal processor circuit 2 to generate a cancellation signal. While in case of a high speed, a sufficient cancellation signal can not be taken off from said circuit 2, then a car speed detector circuit 3, preset car speed detector circuit 4 and timer circuit 5 are used to generate the cancellation signal with the lapse of a certain time. Outputs from said both routes are obtained with OR result in an OR circuit 6, to return a winker switch 9, turned on for operating flickering, to a neutral position through an output circuit 7 and flickering stoppr mechanism 8.

Abstract: PURPOSE:To produce a one component toner capable of carrying out development by a simultaneous process by forming toner nuclei using a thermoplastic resin as binder resin, copper sulfide as a P-type semiconductor, and a magnetic material, etc. and coating the surface of the toner nuclei with an insulating material. CONSTITUTION:CuS as a P-type semiconductor 2, another pigment 4, and a magnetic material 3 (e.g. Fe3O4, etc.) are dispersed in a thermoplastic resin such as polyacrylonitrile, etc. as binder resin 1, to form toner nuclei 5. An insulating material 6 such as hydrophobic colloidal silica, etc. is coated on the surface of the toner nuclei with 10-90% percentage of covering to obtain thus a one component toner. Since a P-type semiconductor is used therein and the toner nuclei are coated with an insulating material, the charge injection in a developing stage is carried out at a semiconductor part, and transfer is carried out using the electric charge of the previously charged insulated part because of absence of injection of reverse electric charge to the semiconductor part. Thus, a satisfactory transferred picture image is obtained without being influenced by the humidity.

The rail 7 moves along the axis-X on an axis-X carrying rail. This rectlinear movement is transmitted to a position-detecting potentiometer 5 by pulleys 100, 101 and the wire l 1 ' to rotate the potention meter 5 nearly synchronizedly with the motor 1. Thus, the potentiometer 5 is set in response to the position of the rail 7 and a type disc 8 is succession, with high accuracy. Thereafter, the output of the potentiometer 5 is inputted into the other input terminal of the amplifier 3, so that the motor 1 is stopped when the position-X signal input becomes equal to the output signal of the potentiometer 5. Consequently, the stop position of the rail 7 is set at a desired position-X.
