In an olefin series flooring material according to the present invention, a printed layer 4 containing synthetic resin is laminated on a lower surface of a surface resin layer 2 containing olefin series resin, and a base material layer 3 containing olefin series resin is integrally laminated on a lower surface of the printed layer 4 via an adhesive layer 5. The adhesive layer 5 contains carboxylic acid denaturation propylene-1-butene copolymer resin and carboxylic acid denaturation propylene-ethylene-1-butene copolymer resin, and a mass ratio of the carboxylic acid denaturation propylene-1-butene copolymer resin/the carboxylic acid denaturation propylene-ethylene-1-butene copolymer resin falls within the range of 55/45 to 95/5. According to this olefin series flooring material, sufficient adhesive strength for the printed layer can be obtained.
摘要:
A non-halogen series floor material includes an intermediate resin layer containing filler, resin having no chlorine atom in chemical structure as a primary resin ingredient and amorphous poly α-olefin resin whose number average molecular weight is 20,000 or less. The content of the amorphous poly α-olefin resin is 5 to 40% by weight with respect to entire resin ingredients. On the upper surface of the intermediate resin layer, a surface resin layer having a thickness of 30 to 1,000 μm is integrally formed. The surface resin layer includes no chlorine atom in chemical constitution. On the lower surface of the intermediate layer, a heat shrinkage-characteristic cloth is integrally formed by heating it to form a backing layer. This provides a non-halogen floor material that hardly generates toxic gases at the time of burning, can be manufactured at a low cost and is excellent in wear resistance, stain resistance, dimensional stability and workability.

First and second voltage buffers are added to an amplifying circuit including input and output amplifying stages in which a P-MOS transistor and an N-MOS transistor operate as a push-pull circuit. An input of the first voltage buffer is connected to an output of the amplifying circuit, and an output of the first voltage buffer is connected via a first phase compensating capacitor to a gate electrode of the P-MOS transistor, and is connected via a second phase compensating capacitor to a gate electrode of the N-MOS transistor. An input of the second voltage buffer is connected to the output of the amplifying circuit, and an output of the second voltage buffer is connected via a third phase compensating capacitor to the gate electrode of the P-MOS transistor, and is connected via a fourth phase compensating capacitor to the gate electrode of the N-MOS transistor.

There is disclosed an invention for generating contract information for an image forming apparatus for which the user is going to conclude a contract. The history information of an image forming apparatus used by the user and having a contract history is stored and managed in correlation with the user. Such management is executed in a center server capable communication with the image forming apparatus through a predetermined communication channel. The above-mentioned information includes contract term, machine type, number of print outputs etc. of the image forming apparatus. Also the image forming apparatus to be managed includes that currently contracted and that contracted in the past. In case the user wishes to conclude a new contract for an image forming apparatus, new contract information is generated according to the history information managed by the center server in correlation with the user. This invention provides a system capable of realizing the foregoing.

摘要:
In an image processing apparatus, an image signal generator includes a ROM and a D/A converter. The ROM consists of gain conversion tables. A PWM signal generator includes a frequency divider, a flip-flop, an integrator, a voltage divider, and a comparator. The frequency divider is synchronized with the ROM in response to a sync selection signal. An output from the frequency divider is further frequency-divided by the flip-flop and then converted into a triangular wave signal by the integrator. The bias component of the triangular wave signal is adjusted by the voltage divider. The resultant signal supplied to one input terminal of the comparator is compared thereby with an output from the D/A converter, thereby obtaining a PWM signal. The peak and bottom values of the triangular wave signal are always matched with the maximum and minimum values of the output from the D/A converter.

Provided are: a first entry preventing nail that interferes with a cartridge at a position closer to an insertion/extraction port than an insertion completed position of an insertion-side end face of the cartridge inserted first; a second entry preventing nail at a position with a space from the first entry preventing nail slightly longer than length of the cartridge, which allows entry of the cartridge and retreat of the first entry preventing nail at that position when a tapered face of the cartridge is at that position while preventing the entry of the cartridge and retreat of the first entry preventing nail at that position when the tapered face of the cartridge is not at that position; and a linkage module which allows advancing and retreating actions of the first and second entry preventing nails in a tradeoff relation.
