To prepare a shaped product comprising a thermal adhesive fiber under moisture and having a fiber aggregate nonwoven structure. In the shaped product, the thermal adhesive fibers under moisture are melted to bond to fibers constituting the fiber aggregate nonwoven structure and the bonded fiber ratio is not more than 85%. The shaped product has an apparent density of 0.05 to 0.7 g / cm3, a maximum bending stress of not less than 0.05 MPa in at least one direction, and a bending stress of not less than â…• of the maximum bending stress at 1.5 times as large as the bending deflection at the maximum bending stress. The moistenable-thermal adhesive fiber may be a sheath-core form conjugated fiber comprising a sheath part comprising an ethylene-vinyl alcohol-series copolymer and a core part comprising a polyester-series resin. Such a shaped product can be used for a building board or the like since the shaped product has a high bending stress although the product is light and has a low density.

Blackboard eraser

A blackboard eraser including a cube having two semi-cylindrical grooves symmetrically arranged in a longitudinal direction therein, and a central brush atop an elevated surface formed between the two grooves. A longitudinal groove is defined underneath each of the send-cylindrical grooves, and equal-length side brushes, which are affixed to an inner surface of a lid, are respectively positioned in the longitudinal grooves. Two grooves are arranged adjacent to each end of the semi-cylindrical grooves, which provide for a shaft affixed to each end of a roller to dispose therein. The brushes and the rollers form the eraser, which are enclosed within a closed chamber between the lid and the two semi-cylindrical grooves. When erasing chalk dust from a blackboard, the chalk dust sticks to the rollers and is carried to the side brushes. The side brushes then wipes the dust, which falls into the closed chamber.

Combination writing instrument

A writing instrument, which has an inner and outer writing element with separate writing medium reservoirs. The writing elements are coaxially mounted in an outer barrel and axially moveable with respect to one another. A driving mechanism may be actuated to allow a user to selectively extend one writing element. The inner and outer writing elements may have an inner sleeve therebetween to improve, for instance, rigidity of the outer writing element and to prevent contamination of the writing medium reservoirs. An outer sleeve may also be provided over the outer writing element. The outer sleeve can function to hold various components of the outer writing element together, and to allow for clean and easy refill of the outer writing element, especially when the outer writing element is a porous nib with a filler-type writing medium reservoir. The writing instrument is designed so that a user can replace the inner and / or outer writing elements when their respective writing medium have been expended.

Applicator, applicator cap and a container having an applicator cap

A cap assembly for closing a container. The cap assembly has: (i) an undercap having a cap body with a top end (or wall) and with at least one endless side wall depending from the top end (or wall) to form a housing for receiving the neck of a container; (ii) an overcap having an overcap body with a top end and with at least one endless side wall depending from the top end to form a housing for receiving and engaging the (cap body of the) undercap; and (iii) an applicator having a stem with a first end for engagement with, or integrally formed with, the undercap within the housing, so that the stem projects from the housing, and a second free end for applying product. The exterior of the undercap body has a series of circumferentially arranged teeth for interengagement with a corresponding series of circumferentially arranged teeth within the housing of the overcap. The two series of teeth being interengageable at a number of relative positions, so that the relative orientation of the overcap to the undercap can be selected. As the undercap is adapted to be attached to the container, relative orientation of the overcap and the container is thus also selectable. In an alternative arrangement the two series of teeth form a safety or child proof cap arrangement. However, the application of a sufficient downward force upon the overcap causes the engagement of the two series of teeth allowing a user to rotate the overcap and undercap in unison. Biasing means may be provided to bias the overcap and undercap apart so that pressure must be applied against the biasing means to remove the cap assembly. Applicators are also provided as an assembly comprising an undercap and an applicator which can be assembled by screwing the undercap on a container into which the applicator has first been placed.

Memory management method, image processing apparatus, and memory management program

When encoding and decoding are concurrently executed by sharing one image memory, the present invention is able to flexibly cope with a situation in which a change occurs in the image size subject to processing. A memory allocation processing block receives information about the image size and the number of images that are specified for each of encoding and decoding, individually allocates the memory areas corresponding to the specified image size by allocating these memory areas to the free area in the image memory in the number equivalent to the number of images, and outputs the addresses of the allocated memory areas. A memory area management block holds memory area information in which the correlation between the identification information of each allocated memory area and the access information for accessing each memory area and receives the requests from the encoder and the decoder for using the allocated memory areas and returning the used memory areas, thereby managing the use status of each memory area on the basis of the memory area information.
