Title: Magnetic head
Inventor: YAMADA HIROKI
IPC: G11B5/23
Filed: 1987-01-30
Abstract: PURPOSE:To obtain a magnetic head having good recording and reproducing characteristics by forming a thin amorphous Co film having 1,000-4,000G saturation magnetization on at least one of the end faces in the gap part of a ferrite core. CONSTITUTION:The thin amorphous Co base film 2 is formed on one face in the gap part of a magnetic head consisting of the ferrite core 1 and a nonmagnetic part 3 consisting of SiO2 is formed on the other face. For example, the thickness of the thin film 2 at this time is specified to 0.8mum, the DC saturation magnetization to 2,500G the initial relative permeability to 15,000, the coercive force to 0.05Oe and the thickness of the nonmagnetic part 3 to 0.4mum. The thin film 2 is magnetically satd. at the time of recording and, therefore, the magnetic head of a wide gap is obtd. The leakage magnetic flux from a magnetic recording medium is slight and since the magnetic permeability of the thin film 2 is large, the magnetic head of a narrow gap is obtd. at the time of reproducing. The magnetic head having the good recording and reproducing characteristics is thus obtd. if the head is constituted in such a manner.

Abstract: PURPOSE: To reduce the load so that the data wheel may be properly positioned and prevented  from rotating even upon an impact by providing day wheel regulating means which is engageable  with the day wheel to operate it in the thickness direction of a plate.   
     CONSTITUTION: A cylindrical wheel 2 rotates twice a day, and a date wheel 3 meshing therewith  rotates once a day. When it reaches 0 c'clock am, the shown condition is established, and the  pawl 3a of the wheel 3 brings the teeth of a date wheel 6 into an advanced condition whereas a  day advance pawl 5 brings a day wheel 7 into an advanced condition. On the other hand, the  cam-shaped projections 3b and 3c of the wheel 3 are brought into engagement with the projections 4a and 4c of a regulating lever 4, respectively, to gradually move the lever 4 down. Then,  the pin 4b at the leading end of the lever 4 is moved down so that its slope engages with the teeth  of the data wheel 6. This is similar to the day wheel. Moreover, the pawl 3a of the data wheel is  brought into enagement with the teeth of the wheel 6 so that the pawl 5 is advanced to a day star  7. Before long, the pins 4b and 4d of the lever are disengaged from the wheel 6 and the star 7 so  that the lever 4 restores its normal condition with the aid of the spring force to stop the wheel 6  and the star 7.

Title: Telephone set
Inventor: FUKUMURA YUKIO
IPC: H04M1/00
Filed: 1990-01-30
Abstract: PURPOSE:To inform an incoming call without causing a fault to an audible sense of a user by providing an incoming call sound volume control means controlling the sound volume of an incoming call tone and using the incoming call sound volume control means so as to send an incoming call tone increasing gradually from a receiver used for the talking. CONSTITUTION:When an incoming call detection circuit 31 detects the presence of a call and informs the call presence to an incoming call tone volume control circuit 32, the incoming call tone volume control circuit 32 controls tone volume changeover switches 51-54 so as to be closed sequentially thereby increasing the incoming tone sequentially from the incoming call detection circuit 31 to an incoming tone amplifier circuit 33. The incoming tone amplifier circuit 33 amplifies the incoming call tone and supplies it to the receiver 22 and a hybrid circuit 2 outputs an incoming call tone as an audible tone from the receiver 22. Thus, the incoming call tone gradually increasing is obtained from the receiver 22 at the arrival of the incoming call. Since the user notices the arrival of the call before the incoming tone is larger, the arrival of the call is informed without causing a defect to the audible sense of the user.

Abstract: PURPOSE:To prevent malfunction from being performed by transmitting a status signal to a mobile machine periodically, applying reset on a telephone set when no folding signal is received within a prescribed time, and afterwards, recovering the telephone set to its original state by an initializing signal. CONSTITUTION:When the synchronization of a signal interface between the telephone set 1 and the mobile machine 2 is taken, the status signal from a control part 5 can be received after the prescribed time, therefore, an autonomous reset counter 6 is reset. Here, no count-up of the autonomous counter 6 is performed, and the control part 5 continues its operation, and outputs the status signal again. Also, when step out is generated, the reset is applied on the control part 5 by a reset signal from the autonomous counter 6 after the prescribed time when the status signal is transmitted. Therefore, the autonomous reset counter is reset by the initializing signal, and the synchronization can be recovered.

Thereafter, the signal CH1 is inputted to a switching circuit 6a for switching between the signal CH1 and a Y signal of a video signal, and the signal CH2 is inputted to a switching circuit 6b for switching between the signal CH2 and a C signal of the video signal, and rotary magnetic heads 8a and 8b are used to record signals on the magnetic tape by recording amplifies 7a and 7b. Thus, the signal CH1 is recorded on an extension of the Y signal, and the signal CH2 is recorded on an extension of the C signal.
