    摘要: This invention provides a method for the manufacture of a high-expansion type absorbent polymer by first causing an absorbent polymer which is obtained by polymerization of a monomer and is possessed of an alkali salt of acrylic acid as a component of polymer to be cross-linked at the time of azeotropic dehydration thereof with a cross-linking agent possessing two or more functional groups in the presence of an inorganic salt and subsequently drying the cross-linked polymer. By the method of this invention, there can be obtained a high-expansion type absorbent material which absorbs water quickly and forms a gel not viscid but permeable to gas. This absorbent material is highly advantageously used as absorbent for sanitary materials free from leaking water and as a water-retaining agent for agricultural applications hardly causing rotton plant roots.

    摘要: In a flash photographing apparatus, a flash device is arranged to slow the rise of flashing characteristic thereof at the initial stage of flashing. To attain this purpose, the electric charge of a first capacitor is impressed via an inductance onto a flash tube at the initial stage of flashing. Following this, the electric charge of a second capacitor is directly impressed on the flash tube without passing through the inductance.

    摘要: A flash device for a photographic camera is arranged either to inhibit a flashing action or to shift the control mode of the camera from flash photography to daylight photography in cases where an object to be photographed is located outside of the adequately operatable range of distance. A pre-flashing action is performed to detect a distance to the object when a main capacitor is charged to a given level before the capacitor is amply charged for flash photography. Then flash photographing is performed at an aperture value determined on the basis of the detected distance when the distance is within the adequately operatable distance range. In the case where the detected distance is outside of the adequately operatable distance range, the main capacitor is further charged for an increased flashing power. After that, a distance to the object is again detected by a second pre-flashing action before the flash photographing is carried out at an aperture value determined on the basis of the distance detected by the second pre-flashing action. The flash photographing arrangement thus permits seizing a shutter chance in flash photographing an object located at relatively short distance without waiting until the main capacitor is amply charged.

    摘要: In a flash photography apparatus of the type determining an aperture for flash photography based on an integrated value of the reflected light quantity received from an object to be photographed as a result of pre-flashing, the quantity of light received is reduced when the integrated value thereof reaches a predetermined value. Then, the quantity of light received as a result of pre-flashing performed thereafter is integrated and the aperture is determined on the basis of the above integrated value and a signal indicating that the integrated value of the light quantity received has reached a predetermined value.
