Abstract: Provided is a microvolume liquid dispensing method in which a variable capacity passage section of a liquid passage in a microvolume liquid dispenser is pressurized from the outside and shrunk in a direction that reduces the internal capacity thereof so that a liquid that is within the variable capacity passage section is pushed toward both a downstream passage section and an up stream passage section. A microvolume of the liquid is pushed toward the downstream passage section as a result of the downstream passage section having a much larger liquid passage resistance than the upstream passage section. It is thus possible to precisely drip a microvolume liquid of a picoliter order from the tip opening of a nozzle by simple control.

Abstract: An ink set is provided and includes at least a yellow ink composition, a magenta ink composition, and a cyan ink composition, wherein the yellow ink composition contains as a colorant at least one selected from the group consisting of a compound represented by formula (Y-I) and a salt thereof. where R4 represents a monovalent group; R5 represents —OR6 or —NHR7; each of R6 and R7 represents a hydrogen atom or a monovalent group; X3 represents a divalent linking group; n3 represents 0 or 1; Ar3 represents a divalent heterocyclic group; and Ar4 represents an alkyl group, an aryl group, or a monovalent triazine ring group.

Abstract: In a multilayer network, flexible and cost-efficient restructuring of an upper layer network depending on a change in a network state can be achieved. Each node at each layer includes an event-operation database (305) storing event-operation correspondence information and an operation execution control section (304) that, upon occurrence of an event, refers to the event-operation correspondence information and executes a responding operation. The operation is to send a message indicating the occurrence of the event to a specified node, to set a path that bases a link in at least one upper layer network, or a combination of them. With a node (N15, N13) that has detected occurrence of a predetermined event serving as a start point, nodes sequentially specified execute operations by referring to the event-operation correspondence information stored in their own nodes, whereby the upper layer network (L204) is automatically restructured.

Abstract: The present invention provides a reflex-type screen which is wound up by a winding shaft to be retracted and is unwound from the winding shaft in use. The reflex-type screen comprises a reflection layer which reflects an incident light, a transparent surface protective layer provided on a first surface of the reflection layer, and a back surface protective layer provided on a second surface of the reflection layer, wherein as between the surface protective layer and the back surface protective layer, the one that has a higher loop stiffness value, faces inward when the reflex-type screen is wound up by the shaft.

Abstract: An artificial nipple for a nursing bottle having a nipple top part having at its tip a dispensing hole for dispensing a liquid drink; and an artificial nipple body which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The nipple top part has a rib, which prevents contact between an upper side and a lower side of the nipple top part when the nipple top part is compressed flat, at a portion where gums of an infant touch when an upper lip of the infant is in contact with the artificial nipple body or at an internal surface in the vicinity of the portion.

Abstract: The invention aims to provide an artificial nipple for a nursing bottle which permits close fitting of the nipple to the sucking fossa of an infant while avoiding deformation of the nipple while providing a form that is similar to a human nipple, and which can prevent the upper and lower sides of the nipple from contacting each other during peristalsis-like movements. In view of this, the present invention provides an artificial nipple for a nursing bottle having: a nipple top part having at its tip a dispensing hole for dispensing a liquid drink; and an artificial nipple body which is continuous to the nipple top part, and whose diameter and wall thickness are greater than those of the nipple top part. The artificial nipple is made of a flexible material.

Abstract: A target hitting game machine comprising a main game unit, at least three targets which are arrayed on the left and right sides of the front surface of the main game unit while being located at different height positions on at least one of the left and right sides, each of the targets is movable between a hitting position and a standby position, and a game result evaluating unit for evaluating a game result in accordance with a position of the target, when hit by a player, between the hitting position and the standby position.

Abstract: An electric light display apparatus of the light blocking type comprising slender discharge tubes arranged in parallel rows on the front side of the apparatus and each divided by openable light blocking members into a multiplicity of sections arranged continuously longitudinally of the tube. The sections are exposed or shielded by the blocking members individually to display the desired characters, illustrations or like images with a collection of bright portions and dark portions. The apparatus is simple in construction and less susceptible to malfunctions and displays images of high luminance which are distinctly perceivable visually without requiring a great power consumption.
