IPC: B21J13/02
Filed: 1981-07-15
Abstract: PURPOSE:To form grooves of reverse gradient on inner face of a recessed part of a material and improve dimensional accuray by fitting one insert of a pair of inserts to an inner face of the recessed part of the material and ironing the outer peripheral face of the material by another insert. CONSTITUTION:The tip of a lock pin 11 is set at the inside of inserts 7 disposed radially. A preparatively formed material 1' is placed on it and grooves 2a are fitted to the inserts 7. Then, an upper die is lowered. Since projected parts 5 are positioned at the middle of adjoining inserts 7 in the upper die 3, the projected parts 5 iron the middle part of adjoining grooves 2a of the material 1 when the upper die 3 is lowered. Reverse gradient is formed in the lower part of the grooves 2a, and at the same time, inner peripheral face is formed to a curved face that fits to a spherical face. When the lock pin 11 is lowered, the inserts 7 are moved by elastic force of a spring 10 in centripetal direction and come off from the grooves 2. Then, the upper die 3 is raised, worked forged parts 1 are taken out from the inserts 7.

Title: Device for controlling emission of stroboscopic emission of camera
Inventor: HOSHINO YASUSHI
IPC: G03B15/05
Filed: 1985-05-24
Abstract: PURPOSE:To make possible an exact emission timing by shifting an emission timing value in the direction where the sensitivity of a film changes according to the difference of a full aperture value when a focal length is changed over. CONSTITUTION:A table which determines the relation between a measured distance value and the emission timing value of a stroboscopic emission for each sensitivity of the film is preliminarily stored in a variable focus camera of which the full aperture value changes. The emission timing value is shifted in the direction where the film sensitivity changes according to the difference of the full aperture value when the focus is changed over. The emission timing is thereby determined. The adequate emission timing for the other focuses is thus obtainable simply by storing the emission timing table for one focus. The smaller memory capacity is required and the correct exposing is realized.
