A solid state image pick-up device having a number of static induction transistor image sensors arranged in a matrix form, each static induction image sensor includes a drain region formed by an n+ substrate connected to the earth potential, a channel region formed by an n.sup.- epitaxial layer grown on the substrate, a ring-shaped p+ gate region formed in a surface of the epitaxial layer, an n+ source region formed in a part of the surface of the epitaxial layer surrounded by the ring-shaped gate region and a p+ overflow drain region formed in the surface of the substrate underneath the gate region. By adjusting a time duration of a shutter control signal having a positive voltage applied to the overflow drain region, a time period during which photocarriers, i.e. electrons are flown into the gate region and stored therein, can be controlled at will, and an electronic shutter function can be achieved.

A solid state image sensor including a substrate, an epitaxial layer grown on the substrate, an opaque bottom electrode applied on the epitaxial layer, a photoconductor film deposited on the bottom electrode, a transparent surface electrode applied on the photoconductor film, a reading-out SIT formed in the epitaxial layer and a resetting MOS-FET also formed in the epitaxial layer. A gate diffusion region of the reading-out SIT is connected to the bottom electrode and a source region of resetting MOS-FET is also connected to the bottom electrode. A source electrode connected to the source region of the reading-out SIT is extended under the bottom surface, while an insulating layer is interposed therebetween to form a capacitance. Charge carriers stored in the gate region of the reading-out SIT can be read-out to derive a large output voltage due to the amplifying function of the reading-out SIT.

A solid state image pick-up device with a shutter function including a number of charge coupled devices of vertical overflow domain type is disclosed. A light receiving portion comprises a p.sup.- epitaxial layer arranged on a main surface of an n.sup.+ substrate and an n.sup.+ diffusion surface region is provided in a surface of the p.sup.- layer. A p.sup.+ control gate for controlling a potential barrier between the n.sup.+ diffusion surface region and the p.sup.- epitaxial layer is formed in the epitaxial layer adjacent to the light receiving portion, and a p well region is formed in the epitaxial layer adjacent to the light receiving portion. During a shutter close period, i.e. before a signal charge storing operation, a control voltage applied to the control gate and a reverse bias voltage applied across the n.sup.+ substrate and p.sup.- epitaxial layer are so adjusted that a potential barrier between the epitaxial layer and surface region is made sufficiently small to completely discharge all the charge stored in the light receiving portion into the substrate serving as the overflow drain.

There is disclosed a process for producing a resin molded article by using a resin into which fine metal particles are so introduced as to be hardly dissolved at the melting temperature of the resin and as to obtain high solubility in a high-pressure carbon dioxide. This process comprises the steps of forming a high-pressure fluid by dissolving, in a high-pressure carbon dioxide, a fluorine-containing metal complex and a fluorine-based solution capable of dissolving the same metal complex; introducing the high-pressure fluid into a heated and molten resin; and molding the resin having the high-pressure fluid introduced thereinto, to shape the molded article.
