摘要:
The main object of the present invention is to provide an optical recording medium with no need to use a control subject substance of the PRTR law, capable of using for an optical recording device with a blue laser, and giving consideration to the environmental aspect.To attain the object, the present invention provides an optical recording medium comprising: a reflective layer containing an aluminum composition as the main component including both aluminum or an aluminum alloy and a metal oxide of a metal other than aluminum; and a dielectric protective layer, formed in contact with the reflective layer, containing a niobium composition as the main component including both silicon dioxide or titanium dioxide and a niobium nitrided oxide.

A content reproduction device has a television broadcast reception function and an Internet connection function, and includes a detection unit and a reproduction-output switching unit. The detection unit detects, when a content of a television broadcast is output for reproduction, a content which is the same as the content of the television broadcast and has a resolution higher than a resolution of the content of the television broadcast from among contents available via an Internet. The reproduction-output switching unit switches a content of the output for reproduction from the content of the television broadcast to the content detected by the detection unit if the detection by the detection unit is successful.
摘要:
The present invention is to provide a method for producing a copolymer for a cement admixture, which enables to easily produce a blend of a plurality of copolymers with different monomer compositions in one polymerization operation, and is superior in water reducing performance and/or slump retention ability. Disclosed is a method for producing a copolymer for a cement admixture, which comprises a step of polymerizing monomer components comprising unsaturated polyalkylene glycol ether-based monomer (A) and unsaturated organic acid-based monomer (B), wherein the unsaturated polyalkylene glycol ether-based monomer (A) is added into a reactor in advance and the unsaturated organic acid-based monomer (B) is added thereto with an addition rate thereof changed at least one time.

A transmitter includes: frequency conversion means for collectively frequency-converting terrestrial digital TV broadcast signals inputted such that the frequency of terrestrial digital TV broadcast signals of a viewing desired channel inputted by viewing desired channel input means, among the terrestrial digital TV broadcast signals inputted, are converted to a frequency of a specific unused channel of a predetermined VHF band; filter means for extracting only TV broadcast signals of the specific unused channel of the predetermined VHF band among the TV broadcast signals obtained by the frequency conversion means; and transmission means for amplifying and wirelessly transmitting the TV broadcast signals extracted by the filter means.

A program-guide-display controlling apparatus for displaying a plurality of program guides on a display unit in a matrix form by using one of the ordinate and the abscissa as a channel number axis and another one as a time axis comprises means for displaying to discriminate a time period in which a purchased program is present and a time period in which the purchased program is not present, so as to ensure that a situation in which two or more PPV programs which are broadcast during the same time period happen to be purchased is made difficult to occur.
摘要:
The present invention provides: a cement admixture which displays excellent cracking inhibition effect and brings about good fluidity even if the quantity of the cement admixture as added is small; and a cement composition comprising this cement admixture. The cement admixture comprises a polyalkylene glycol (A) and a polyalkylene glycol mono(meth)acrylate/unsaturated carboxylic acid-based copolymer (B), wherein: the average molecular weight (X) of the (A) is in the range of 400 to 10,000; the average molecular weight (X) of the (A) and the average molecular weight (Y) of a polyalkylene glycol chain portion of the (B) satisfy 0.9
摘要:
The present invention provides a cement admixture and a cement composition, both of which displays little dependence of the water-reducibility upon temperature in that these cement admixture and cement composition involve little slump loss at high temperature and little increase in the amount of addition at low temperature. The cement admixture comprises either or both of the following components: copolymer (A) which includes constitutional unit (I) of general formula (1) below and constitutional unit (II) of general formula (2) below as essential constitutional units and may further include constitutional unit (III) of general formula (3) below, wherein the content of constitutional unit (III) is 45 weight % or less of copolymer (A); and copolymer salt (B) which is obtained by further neutralizing copolymer (A) with an alkaline substance.
摘要:
A theft detection mechanism is provided with a top ring which is depressed when a foreign object other than a key is inserted into a key inserting hole. A sensor is provided for detecting that the top ring is depressed. A top ring is inevitably pushed down when a foreign object other than a key is inserted into a key inserting hole to activate the sensor, thereby reliably detecting a stealing action. Moreover, the structure of a theft detection mechanism is made simple to reduce the cost thereof.
摘要:
A coil bobbin for a magnetic head in which a recording and reproducing coil bobbin and an erasing coil bobbin each having a hole made therein for inserting a core are formed into an integral structure by being coupled at one end portions thereof through a flange with holes made therein for inserting cores. Terminal pins are provided on the flange, to which the coil winding ends are connected, and a flexible printed circuit board is connected to the coil windings by placing terminal pin insertion holes formed therein over the terminal pins on the flange.
