Abstract:
In a filtering dispenser container which includes a plug attached to a mouth portion of a bottle thereof and having a liquid discharge passage, and a filter and a check valve provided in the discharge passage, air lock is prevented, even if the container contains a highly percolative liquid, by preventing a very small amount of liquid percolating the check valve from reaching the filter. In the filtering dispenser container, a dam (14) is provided between the check valve (23) and the filter (25) for retaining a very small amount of the liquid percolating the check valve (23) when the check valve is closed. Thus, the filter (25) is prevented from being wetted with the liquid percolating the closed check valve (23) during storage or delivery of the container before the first use of the container.
Abstract:
A printer with a plurality of ink ribbon cassettes is capable of printing characters or designs with a selected one of these ink ribbon cassettes. The printer includes a vertically movable cassette table on which the plurality of ink ribbon cassettes are mounted in a stacked relationship, a stepping motor, and a rotary cam mechanism for moving the cassette table up and down when the stepping motor drives to rotate the rotary cam mechanism. There is further provided a memory for pre-storing the rotational speed data for each rotational angle of the rotary cam mechanism according to a variation pattern of load applied to the stepping motor together with the rotation of the rotary cam mechanism. The rotational speed of the stepping motor is controlled accoding to the rotational speed data corresponding toe ach rotational angle of the rotary cam mechanism read out of the memory.
Abstract:
An illumination control system includes: illumination apparatuses having respective addresses and perform a dimming control in response to a dimming signal inputted from an outside, and an illumination control terminal which has an imaging device, a capturing range of which is set to include illumination ranges of the illumination apparatuses. The illumination control terminal segments an image captured by the imaging device into a plurality of areas so that the areas correspond to the illumination ranges, detects a person based on the captured image, determines a segmented area in which the person is present if the person has been detected and performs dimming control on an illumination apparatus corresponding to the determined segmented area.
Abstract:
A brightness sensing system includes an image pickup unit for taking an image of a target space and a calculation unit for calculating the brightness of an image pickup area based on the image taken by the image pickup unit. In the brightness sensing system, if the difference or the ratio between an image as a whole and a pixel block formed of one or more pixels is equal to or greater than a threshold in terms of brightness change between a previously-taken reference image and a currently-taken target image, the calculation unit excludes the pixel block from comparison candidates and compares the brightness of the target image with the brightness of the reference image based on the remaining pixels other than the pixel block.
Abstract:
Conductive or solder bumps are stacked between a mounted component such as a BGA device and a printed wiring substrate in a multileveled printed circuit board unit. An interposer or relay substrate is interposed between the adjacent stacked conductive bumps. The interposer substrate is made of a porous material. When any difference in the expansion is caused between the printed wiring substrate and the mounted component, one side of the interposer substrate receives a relatively smaller displacement force while the other side of the interposer substrate receives a relatively larger displacement force. A shearing stress is induced in the interposer substrate. Deformation of the porous material serves to absorb the shearing stress in the interposer substrate. The conductive bumps bonded on one side of the interposer substrate as well as the conductive bumps bonded on the other side of the interposer substrate may be relieved from a shearing stress. Accordingly, the durability of the conductive bumps can be improved. The conductive bumps are allowed to keep a stronger bonding in a longer duration.
Abstract:
A method for altering a circuit pattern of a printed-circuit board includes the steps of removing a portion of the printed-circuit board so that the circuit pattern inside the printed-circuit board is exposed, and connecting an exposed portion of the circuit pattern to another portion of the printed-circuit board by a conductive body so that a circuit path is formed between the exposed portion of the circuit pattern and the other portion of the printed-circuit board.

Abstract:
A printed-circuit board includes an insulating substrate, at least one insulating layer formed on the substrate, a circuit pattern formed on the layer, and a protective coating layer formed on the insulating layer having the circuit pattern formed thereon. The circuit pattern has a location to be cut, if necessary. A material of the protective coating layer is at least partially eliminated from two zones which are disposed at sides of the location to be cut, and a material of the insulating layer may be further at least partially eliminated from those zones.
Abstract:
An illumination apparatus includes a light source; a sensor which has an image sensor and detects an illuminance and a presence of a human based on a captured image while setting a range overlapping a range illuminated by the light source as a visual field; an illuminance determining unit for varying a light output from the light source based on the illuminance and the presence of a human; and a dimming control unit. The illuminance determining unit obtains an illuminance of an illuminance maintaining area included in the visual field based on the captured image, and when the sensor detects no human, the illuminance determining unit reduces the light output while maintaining the illuminance of the illuminance maintaining area to be equal to or greater than a threshold that is set in advance as a lower limit illuminance, which makes it feasible for the image sensor to capture an image.
