摘要： A magnetic head unit is provided by which damage to a conductive-pattern layer formed on a spring arm during a bending process of the spring arm can be prevented. The magnetic head unit comprises a magnetic head and a spring arm having a bent portion which is bent to generate an elastic force. The magnetic head is mounted on an end of the spring arm. At least one conductive-pattern layer is formed on a surface of the spring arm to extend from a gimbal portion where the magnetic head is mounted to a attachment portion where the spring arm is mounted to a member of a magnetic head driving mechanism. The bent portion has a first portion and a second portion separated from the first portion. The conductive-pattern layer passes through the second portion. No external force is applied to the conductive-pattern layer formed during a bending process for the bent portion. A dispersing-pattern layer may be provided for dispersing an external force exerted on the conductive-pattern layer during the bending process of the bent portion so that said conductive-pattern layer is protected from being damaged due to the external force being concentrated onto said conductive-pattern layer.

摘要： A method of processing a silver halide photographic material comprising processing the silver halide photographic material in the presence of an antifoggant which is an organic compound which loses its developing restraining function by a reduction oxidation reaction with oxidized developers. The method improves the discrimination between image and non-image areas of the silver halide photographic material by the novel antifoggant which restrains fog selectively in non-image areas without decreasing photographic sensitivity and image density. The organic compound can be an anti-foggant which possesses a moiety according to the Kendall-Pelz rule and either a mercapto group or a cyclic NH group.

摘要： A two-equivalent cyan dye forming coupler represented by the general formula (I) substituted with at least one substituent represented by general formula (II), having substituents as defined in the specification. This coupler has excellent color forming properties and good dispersibility as well as good color hue and excellent fastness to heat and light. The color photographic material containing the two-equivalent cyan dye forming couplers does not exhibit a decrease in color density of cyan color images even when it is processed with a bleaching solution which has a weak oxidation power or a bleaching solution which is exhausted.

摘要： A process for excavating and constructing a tunnel, and an excavating device are disclosed. This process is directed to excavating and constructing a tunnel under a railway or a road on a bank or on level land in the direction transverse to the railway or road. In this process, pits are dug on the opposite sides of the railway, and then an excavator digs into the wall of a pit on one side so as to go out of the wall of the other pit through the ground left therebetween. In this respect, a hollow casing unit of a box shape is coupled to the rear end of the excavator equipped with a screw conveyor. As the excavator advances or digs forward a given distance, another casing unit is in turn coupled to the rear end of the preceding casing unit, and then such a step is repeated, until the excavator goes out of the wall of another pit. In this manner, the excavator further digs into the wall of one pit in the position adjacent to the preceding run of casing units. Then, these runs of casing units are placed around the imaginary contour of a tunnel, thereby forming the outer wall of the tunnel. The sand and soil inside the outer wall of the tunnel are excavated and removed, after which reinforcing steel bars and a mold are placed along the inner surface of the wall of the tunnel. Concrete is then poured into the hollow casing units themselves as well as between the mold and the wall. Thus, the hollow casing units form an integral part of the wall of a tunnel, as an outer wall.
