摘要:
A semiconductor optical pulse compression waveguide with a novel structure that can greatly reduce its size, and be simply fabricated. The semiconductor optical pulse compression waveguide is composed of a semiconductor optical waveguide which guides an optical signal and includes an optical pulse compression region. The optical pulse compression region includes at least one saturable amplifier region that loses its amplification characteristic after amplifying a fixed amount of optical energy, and at least one saturable absorber region that loses its absorption characteristic after absorbing a fixed amount of optical energy, where the saturable amplifier region and the saturable absorber region are disposed alternately in series in the optical pulse compression region.

The vibration of a vibratory element, caused by applying thereto a shock, is detected by a vibration sensor and provided as an electric shock signal to a resonance circuit. The resonance frequencies and resonance decay time of the resonance circuit can freely be adjusted. By setting the resonance frequencies and resonance decay time of the resonance circuit to arbitrary values, desired frequency components are extracted from the electric shock signal and output as a sound signal of an electronic musical instrument.

Disclosed is a solution circulation type metal-halogen battery in which an electrolyte is circulated between a reaction tank and an electrolyte storage tank. This battery has a first group of rectifying plates and a second group of rectifying plates aligned in a row, respectively, so as to partition between the inlet of the electrolyte and the reaction tank and between the outlet thereof and the reaction tank, respectively. These first and second groups of rectifying plates are formed in such a manner that the interval between the respective rectifying plates increases in accordance with a predetermined functional equation in the direction of moving away from the inlet or outlet side of the electrolyte. This apparatus equalizes the flow rate and velocity of the electrolyte flowing through the reaction tank, thereby preventing the occurrence of an overvoltage or a faulty deposition of metal resulting from the non-uniform flow of the electrolyte.

In a multi-user communication system in which communication is carried out between a display apparatus and multiple information terminal apparatuses (a moderator terminal apparatus and a user terminal apparatus) over a network, the moderator terminal apparatus sends, to the display apparatus, a data ID (ID information) for identifying data to be displayed in a display unit of the display apparatus, user information indicating a user that is an owner of that data, and access rights information that is set for each user using the information terminal apparatuses and that indicates whether or not the generation and changing of that data is permitted. The display apparatus displays the data identified by the data ID (ID information) in the display unit based on the user information and the access rights information.

Provided is a powdered raw material, which is housed in a housing portion (12) of a type of a bottle cap 1 which has the housing portion (12) that houses the powdered raw material, and of which the housing portion (12) is opened by an uncapping operation, and then causes the raw material to be released into the bottle. Using a multi-functional powder property measuring instrument multi-tester, the powdered raw material is dropped onto a watch glass from a powder falling point, a dropped mass and a mass on the watch glass are measured, and a degree of dispersion which is obtained from the following formula (1) is equal to or more than 5% and equal to or lower than 40%. degree of dispersion[%]=(dropped mass−mass on the watch glass)/the dropped mass×100 (1)
摘要:
An image processing apparatus includes an image converting section, a scanning controlling section, an image memory, and an object detection processing section. The image converting section converts a size of input image data. The scanning controlling section stores the size-converted image data, performs a scanning process of moving a square region having a predetermined size in the size-converted image data, and successively extracts square region image data. The image memory stores the square region image data which have been extracted by the scanning controlling section. The object detection processing section which detects an object region from the extracted square region image data. The image memory stores a plurality of entries of object candidate image data containing object regions of a plurality of object candidates. The object detection processing section performs an object determining process of determining whether or not the square region image data contain an object region.
