Title: Mirror holding frame for single-lens reflex camera
Inventor: KATAYAMA AKIRA
IPC: G03B19/12
Filed: 1982-10-21
Abstract: PURPOSE:To eliminate camera shake and the operation sound for turning and stop of a mirror, by providing a piercing part on one of planes of both faces of a mirror holding frame body at least to reduce the weight while holding the strength. CONSTITUTION:Many piercing holes 11 are formed as meshes of a net throughout a surface 1A of a mirror holding frame body 1 which holds the mirror turned between a finder observation position and a photographing position. Thus, the mass is reduced considerably without changing the position of a gravity center G of the mirror holding frame body 1 and reducing the strength of the mirror holding frame body 1. Consequently, since the inertia moment due to the turning center of an arm plate 2 becomes smaller, the angular motion quantity of the mirror holding frame body 1 is reduced, and the shock in case of a sudden stop of turning of the mirror holding frame body 1 is reduced, and the camera shake for this sudden stop is lessened.

Filed: 1990-07-13
Abstract: PURPOSE:To improve the accuracy and monotonosity of a pulse width by providing plural stages of delay gates, plural differential amplifiers, a control circuit and a pulse generating circuit and varying the pulse width with a delay signal whose delay time is controlled with high accuracy. CONSTITUTION:A delay time Td from the application of an input pulse signal Sin. to a delay circuit 1 at a point of time t0 till a delay pulse signal Sd appears at a point of time t1 is proportional to a stage number of delay gates G through which the input pulse signal Sin fed to the input terminal of the delay circuit 1 passes. Thus, when the input pulse signal Sin is delayed by a time, the input pulse signal Sin passes through number of delay gates corresponding to a number resulting from a desired delay time divided by a delay time per one delay gate. Let the delay time per one stage of delay gate be 120ps, the delay time is controlled by a very thin step. As a result, a pulse width of an output pulse signal Sout is varied finely with high accuracy.
