Title: Noise prevention device of speed change gear
Inventor: FUKUNAGA KEIGO
IPC: F16H57/12
Filed: 1981-08-13
Abstract: PURPOSE:To prevent generation of an abnormal noise caused by contact and separation of tooth surfaces in case of light load by applying a predetermined load to a speed change gear when load applied to the speed change gear is light load, less than a predetermined value. CONSTITUTION:When light load less than a predetermined value is connected or coupled to an output shaft 11 to make an operating switch of an electric motor 1, rotation of a rotary shaft 4 of the electric motor 1 is transmitted from the first gear 5 through the second gear 6, the third gear 7, the fourth gear 10 to the output shaft 11. An electric current from the electric motor 1 flows through a conductor 15 to a converter 16, and the current value is increased by the converter 16. The increased electric current flows from the converter 16 to a conductor 17. As a load disc 14 is rotated to cut magnetic field generated in the conductor 17, load is produced, so that a predetermined load is applied to each tooth surface of gears of a speed change gear 2, thereby to keep tooth surfaces engaged with each other from contacting and separating so as to prevent generation of an abnormal noise.

Title: In-calling incoming display system
Inventor: NAKAMURA JUNJI
IPC: H04M3/42
Filed: 1986-06-03
Abstract: PURPOSE:To make an incoming display without disordering an image when there is an incoming signal during image communication by providing an image information center with a detecting means for a request signal and a generating means for an incoming display image signal to a picture terminal. CONSTITUTION:When the VCW signal detecting circuit 61 of a terminal device 6 detects a signal VCW, a CWRQ generation instruction circuit 62 sends out a generation instruction for a signal CWRQ to the image terminal 11. The image terminal 11 of a common-use subscriber 1 when receiving the generation instruction for the signal CWRQ generates the CWRQ. which is transmitted to the image center 3a. The CWRQ detecting circuit 31 of the image center 3a when receiving the signal CWRQ operates a CWPIC generating circuit 32 to edit and transmit an incoming display image signal CWPIC to the image terminal 11 in communication. The image terminal 11 receives the signal CWPIC and displays the arrival of an incoming call during calling on the screen. Consequently, when the incoming call is generated during the image communication, the incoming call is displayed on the without disordering the image.
