Title: Finder optical system
Inventor: KATOU MASATAKE
IPC: G03B13/06
Filed: 1984-05-07
Abstract: PURPOSE:To display information by a finder image and to simplify the structure of the finder optical system of an electronic camera by arranging a prism for information on the 2nd prism of the pentagonal prism of a finder. CONSTITUTION:A light beam E which is passed through a photographic lens and reflected by a reflecting mirror is incident on the pentagonal prism P through a focusing screen 503. The pentagonal prism P consists of the 1st prism 10 and the 2nd prism 11. Then, the light beam E is reflected by reflecting surfaces of the 1st and the 2nd prisms 10 and 11 and projected from a reflecting surface S6 to reach an ocular lens. Further, the prism 502 for information is arranged on the incidence surface S4 of the 2nd prism 11, and consequently various pieces of information are displayed near a photographic image through the finder. Thus, the information prism 502 is arranged on the 2nd prism and the distance between the screen 503 and ocular lens is shortened, so the finder has the high visual field rate and is reduced in size.

Title: Magnetic recording and reproducing device
Inventor: GOTOU SHIYOUJI
IPC: G11B15/675
Filed: 1981-06-15
Abstract: PURPOSE:To reduce the generated torque of a motor, and to reduce the size of a device, by transmitting the power of the motor not to a capstan, but to only a cassette carrying means in cassette unloading mode. CONSTITUTION:For cassette loading, the rotation of a motor 4 is transmitted to a motor pulley 122 through a unidirectional rotating clutch 124 to rotate capstans 172 and 174. When a tape is run, the rotation of the motor 4 shown by an arrow 126 allows a sun gear 136a to rotate as shown by an arrow 184 through gears 128, 130, 132, and 134, but the rotation of a gear 154 is restricted, so a carrier 148 rotates as shown by an arrow 188. For cassette unloading, the motor 4 reverses, so the unidirectional clutch 124 is not engaged, so that neither capstan 172 nor 174 is driven. The turning force of the motor 4, on the other hand,  is transmitted to the sun gear 136a and the rotation of the carrier 148 is restricted by a shaft 160, so the rotation of the sun gear 136a is transmitted to the gear  154, a double-state gear 8, and a gear 12, thereby ejecting the cassette.

Pebble- shape having the diameter of 0.05-0.5mu, cube-shape having the length less than 4mu, or disk-shape having the thickness of 0.05-0.5mu is most suitable. The percentage of the metallic powder mixture in the adhesive is suitably 1-16vol.%.
