Title: Magnetic recording and reproducing device
Inventor: HAMAGUCHI MASAKAZU
IPC: H04N5/92
Filed: 1988-11-02
Abstract: PURPOSE:To eliminate the need for the preparation of separate reproducing devices by providing the 1st mode recording/reproducing an existing broadcast system NTSC video signal and the 2nd mode recording/reproducing a band compression high definition video signal and using an input video signal identification signal so as to select the mode and to record a prescribed video signal. CONSTITUTION:The servo control 80 is set to a prescribed recording mode in response to an identification signal VR of an input video signal to record both the video signals. On the other hand, at reproduction, the reproducing mode is identified depending on the difference in the frequency of a control signal or the difference in the form of the recorded video signal to output an identification signal Vp. Then the servo control 80 is set to the prescribed reproduction mode in response to the identification signal Vp of the reproduction mode, the signal processing circuit 200 is switched and the reproducing signal is processed according to a prescribed format to decode the original video signal. Thus, both the high definition video signal subject to band compression and the NTSC video signal are recorded/reproduced by the same device.

Filed: 1987-10-30
Abstract: PURPOSE:To attain rapid focusing by rotating a lens barrel and moving an image pickup device in the reverse direction to a lens moving direction simultaneously with the movement of a focusing lens. CONSTITUTION:Since the leading direction of a screw face 31 engaged with the focusing lens 4 in the lens barrel 3 is reversed from that of a screw face 32 engaged with the image pickup device 6, the focusing lens 4 and the image pickup device 6 are moved respectively in the reverse directions on an optical axis at the time of rotating the lens barrel 3. When the leading angles of the screw faces 31, 32 are the same, the moving speeds of the lens 4 and the device 6 are the same and their directions are reversed to each other, so that the time required for focusing can be reduced to a half of ordinary time. Thus, rapid focusing can be attained.

Title: Speaker diaphragm
Inventor: AOKI TAKAYOSHI
IPC: H04R7/08
Filed: 1984-12-24
Abstract: PURPOSE:To prevent the occurrence of a ruggedness on the surface of the speaker diaphragm even when the external pressure is applied from the surface skin material and the large input is continuously impressed for a long period by providing the rib between sector repeating patterns of the core material. CONSTITUTION:By installing some ribs 2 on the way to a slender cell 1, the distance between a rib 2 and a rib 2 goes to be short and the diametral strength of the core material is raised. Further, when expansion and shrinkage are executed at the time of bonding front and rear skin materials and core materials by providing a small groove at the upper part of the rib 2, the air in the cell runs away to the external and therefore, the ruggedness can not be made at the surface of the front skin material. When a speaker system is dropped in the packed condition, the ruggedness can be made on the surface of a speaker diaphragm by changing the pressure in an exterior packing, and therefore, special specifications to protect a speaker diaphragm are performed, this becomes unnecessary and the packaging cost can be reduced.
