摘要： An ink-jet head driver comprises: a pressure chamber filled with a recording liquid; a piezo-electric element as electrical/mechanical transducing means for enlarging the capacity of the pressure chamber at a first stage and contracting it in a second stage into the state before enlargement, thereby emitting the recording liquid; and a device for adjusting the time interval between the first and second stages to adjust the emitting velocity. The capacity of the pressure chamber is changed due to charge and discharge by a charging/discharging circuit, and charge/discharge time constants of this circuit are selectively controlled by a control unit. According to this driver, mixture of air into recording liquid in the ink-jet head when the piezo-electric element is expanded is prevented, and a variable range of a dot diameter of the recording liquid droplet can be extended, thereby improving recording quality.

摘要： A picture-forming method comprises the steps of providing picture forming elementary particles having different optical densities; controlling the areas occupied by the respective picture forming elementary particles; and representing gradient by said different picture forming elementary particles while limiting the percentage of the gradient level area represented by the highest density elementary particle to said picture forming elementary particles to under 70% of the total area repsesented by said respective different picture forming elementary particles, thereby giving a picture which does not feel "rough". Apparatus is also disclosed for performing the method.

摘要： A motor drive apparatus constructed to be not only attachable to cameras having mechanical coupling parts of two different types which are ordinarily not interchangeable. A change-over switch inserted in the mode signal transmission line of the motor drive apparatus closes when the apparatus is attached to a camera of the former type and opens when it is attached to a camera of the latter type.
