摘要:
A camera which includes a liquid crystal focusing screen and an exposure control circuit that measures light reflected from the subject to be photographed after its passage through the liquid crystal screen is further provided with a circuit for compensating the light value determined by the exposure control circuit when operating voltage is not applied to the focusing screen so as to thereby compensate the amount of light measured through the screen when the nonapplication of operating voltage to the focusing screen causes the screen to transmit light therethrough less readily than when operating voltage is applied thereto.

An anode for an electrolytic capacitor includes a porous body having micropores that include a dielectric layer filled thereon and an electrolyte filled therein. The porous body includes a laminate of a plurality of sinter layers having the micropores formed from valve metal particles. The laminate includes alternating smaller micropore-size regions and larger micropore-size regions, which form electric conductive passages between the smaller micropore-size regions and side surfaces of the porous body. This structure reduces resistance of the capacitor and also increases capacitance by effectively utilizing the capacitance of the smaller micropore-size regions. The porous body is formed by stacking a plurality of porous preforms, such as sheets preformed of valve metal powder, into a laminate, and then sintering the laminate. The porous body may be joined with a valve metal substrate during sintering, thereby completing the anode for an electrolytic capacitor. Particularly, the porous body may be a laminate including larger micropore-size sinter layers and smaller micropore-size sinter layers, by alternatively laminating two types of preforms, each having a different density.

A mounting structure for a multiple-optical-axis photoelectric switch comprising, a protrusion of a first member attached to cap members located on either end of the main case of one or both of a light receiving body and a light emitting body. The protrusion is interposed between a convex curved surface of a second member and a concave curved surface of a third member. Elongated holes in the protrusion allow the bodies to pivot about an axis containing the light emitters and light receivers. Consequently, a multiple-optical-axis photoelectric switch, mounting structure and fixture can be provided in which the optical axis can be adjusted without being influenced by the limitation in the spaces above and below the main case while the multiple-optical-axis photoelectric switch is mounted at a predetermined mounting part.
