Title: Transfer device
Inventor: SHIOZAWA ETSUO
IPC: G03G15/16
Filed: 1988-03-31
Abstract: PURPOSE:To optimize an obtained image by using two motors of a high precision motor and a high torque motor, rotating a photosensitive drum by means of the high precision motor when a toner image is formed and rotating the photosensitive drum and a transfer drum by means of the high torque motor when the toner image is transferred. CONSTITUTION:When the toner image is formed, the transfer drum 8 is separated from the photosensitive drum 2. At the same time, a clutch 6 is disengaged and the photosensitive drum 2 is rotated by means of the high precision motor 4. When the toner image is transferred to an image receiving sheet, the transfer drum 8 is made to press-contact with the photosensitive drum 2. In addition to that, the clutch 6 is engaged so that both the drums 2 and 8 are rotated by means of the high torque motor 7. Thus, when the toner image is transferred, stable transferring can be achieved by securing a necessary high torque. When the toner image is formed, the rotating precision of the photosensitive drum 2 is heightened, thereby obtaining an appropriate toner image without irregularity.

Title: Dial pulse receiving system
Inventor: MIZUGUCHI TADASHI
IPC: H04Q3/42
Filed: 1981-05-26
Abstract: PURPOSE:To prevent the counter loss of a dial pulse by delaying the timing of inputting a monitoring point signal of a circuit to a dial pulse counting device. CONSTITUTION:A dial pulse from a subscriber 1 is inputted to a dial pulse counting device 4 from a subscriber's circuit 2 through a delaying device 12. The counting loss of the dial pulse can be prevented because a plently time is available from starting of the dial pulse counting device 4 by a common controlling device 5 to arrival of the dial pulse. By this way, it becomes unnecessary to close the network 3 as before when counting the dial pulse, and the amount of processing of the common controlling device can be reduced.

CONSTITUTION:After the first layer 2 of about 50 nm in thickness has been formed using iron as a magnetic material maintaining the temperature of a glass substrate 1 at 400 deg.C, and by performing ionplating for three minutes, the temperature of the glass substrate 1 is lowered to 200 deg.C, ion-plating is performed at the same filmforming speed for fifty minutes, and the second layer 3 of about 900 nm in thickness is formed. Subsequently, the temperature of the glass substrate 1 is raised to 400 deg.C again, and the third layer 4 of about 50 nm in thickness is formed at the same film-forming speed. The pinhole generating density of the Fe magnetic film of 1 mum in thickness formed as above is 2 pinholes/cm<2> as against the pinhole generating density of 10-20 pinholes/cm<2> on the film formed at the substrate 1 temperature of 200 deg.C using the method heretofore in use, and the quality of the magnetic film can be improved sharply.

Title: Handset making use of ear microphone
Inventor: ONO HIROSHI
IPC: H04R1/00
Filed: 1979-06-26
Abstract: PURPOSE:To prevent the generation of the hawling of a handset that uses a vibra- tion pickup type ear microphone available for a talk with a single ear, by providing a correcting device that cancels the output voltage of a receiver. CONSTITUTION:Correcting device 5 has vibration pickup 6 with nearly the same frequency characteristics that sound vibrating pickup 2 of vibration pickup type ear microphone 1 has. Then, both pickups 2 and 6 are arranged at acoustically-equal intervals to receiver 4 via waveguides 7 and also connected to each other so that both outputs will cancel. Therefore, a voltage developed by ear microphone 1 never reaches transmitter 9, and consequently the generation of hawling can be prevented. As a result, the volume of the receiver can be increased and even under noisy conditions, clear sound reception can be attained.
