Provided is a recording material with a superior heat resistance and having a low content of a dihydroxydiphenylsulfone derivative, and a color-developing composition for producing the recording material. With the use of this color-developing composition, a recording material with a superior heat resistance at the background part can be provided and the content of a dihydroxydiphenylsulfone derivative, such as 4,4′-dihydroxydiphenylsulfone, in the color-developing composition can be reduced to 2% by mass or less, or further to 1% by mass or less.

Provided is a recording material with a superior storage property for the background and image, particularly with a remarkable superiority in any of light resistance of the background, and light, moisture and heat resistance of the image. The recording material contains a phenolic compound represented by formula (I) [wherein R1-R3 each independently represent a hydrogen atom or C1-C4 alkyl group; R5 represents a hydrogen atom, C1-C4 alkyl group or C1-C4 alkoxy group, with the proviso that when R5 is a hydrogen atom, R4 is a C1-C4 alkyl group, when R5 is a C1-C4 alkyl group, R4 is a hydrogen atom, and when R5 is a C1-C4 alkoxy group, R4 is a C1-C4 alkoxy group].
摘要:
A spray painting device having a first spray mechanism and a second spray mechanism located downstream of the first spray mechanism in an assembly line along which an automobile body is conveyed. A spray head of the first spray mechanism is fixed at a constant height when spraying paint onto a side outer panel portion which is situated over a front or rear wheel of the automobile chassis, and is moved up and down when spraying paint onto a side outer panel portion which is not situated over the front or rear wheel. A spray head of the second spray mechanism is located so that a constant distance is maintained between the spray heads and the side outer panel to spray a uniform coat of paint onto the side outer panel.

An object of the present invention is to provide a recording material or a recording sheet that is excellent in background and image stabilities and further excellent in color-developing sensitivity. The recording material of the present invention contains a color-forming compound, an additive, and at least one compound represented by formula (I) [wherein R1 and R4 each independently represent a C1-C6 alkyl group or the like; p represents 0 or any integer of 1 to 4; q represents 0 or any integer of 1 to 5; when p and q represents 2 or more, each of R1 and each of R4 are the same or different; R2 and R3 each independently represent a hydrogen atom or the like; R5 represents a hydrogen atom or the like; and the bond represented by the wavy line represents E, Z, or a mixture thereof].
摘要:
A control unit of an electronic-book read-aloud device reads book data and electronic-book data from an electronic bookmark and stores the read data in a storage unit. Further, the control unit sets a read-aloud-start position based on the electronic-bookmark data, reads the book data after the read-aloud-start position from the storage unit, and transmits the book data to a speech-output unit. The speech-output unit converts the book data into a speech signal and transmits the speech signal to a speaker through an amplifier. If the read-aloud processing is stopped, the control unit writes read-aloud-end-position data and read-aloud-date data into the electronic bookmark of the electronic book.

An input device for an information terminal includes an operational experience determining device for determining the operational experience of a user in accordance with the speed of inputting data by the user to a data input screen and a display control device for changing the content on the data input screen in accordance with a result of the determination by the operational experience determining device.
摘要:
A data transfer control system in a data transfer apparatus including a plurality of data processing units having different data transfer speeds and a temporary holding circuit provided between the data processing units for temporarily holding data transferred between the data processing units. The data transfer apparatus sends a transfer request for data corresponding to a data storage capacity of the temporary holding circuit of the data transfer apparatus to the data processing unit on the side of sending data and sends a transfer request for data corresponding to the data storage capacity of the temporary holding circuit after an elapse of a delivering time of data to an information processing unit on the data transferred side of the temporary holding circuit from the time of the data transfer request is sent until the requested data from the data processing unit on the data sending side reaches the temporary holding circuit of the data transfer apparatus.
摘要:
A thin-film magnetic head is provided which includes a substrate having formed thereon an upper and a lower thin-film magnetic core, a thin-film conductor coil, and a thin-film gap. An insulation layer is provided that electrically insulates the coil and the magnetic cores. The insulation layer is formed of an organic silicone resin with a ladder structure that is composed of silicon, oxygen and carbon. A resist is used as a mask to form the pattern of the insulation layer, and then the resin is removed
摘要:
Provided is a color-developing composition containing a molecular compound which has as a component compound a compound represented by formula (I) [wherein Y represents a C1-C12 hydrocarbon group which is chained or branched and saturated or unsaturated, or a C1-C8 hydrocarbon group which is chained or branched, saturated or unsaturated and has an ether or thioether bond; R1, R2, R3 and R4 each independently represent a C1-C6 alkyl group or C2-C6 alkenyl group; n, p, q and r each represents any integer of 0 to 4; and m represents any integer of 0 to 2]. Also provided is a recording material with a sufficient color-forming sensitivity, superior storage stability, and especially with an extremely little background fogging in a heat resistance test.
