Abstract:
A paper ejecting device for ejecting a recording cut sheet cut of a recording apparatus is disclosed. The paper ejecting device includes an ejector for ejecting the recording cut sheet through an outlet which is provided at a portion of the recording apparatus, a tray disposed adjacent to the ejector for receiving and recording cut sheet which has been ejected through the outlet by the ejector, and a sheet reversing member operable between a first position for guiding and reversing the recording cut sheet ejected through the outlet before the sheet falls onto the tray, and a second position for permitting the recording cut sheet ejected through the outlet to be received on the tray, without a reversal of the cut sheet.
Abstract:
In an electrophotographic device, a heat roller is heated by a heater, and upon instruction of start of a print operation, the temperature Tf of the heat roller is detected by a temperature sensor. When the temperature Tf is above a predetermined temperature Tv at which high voltage is applied, the high voltage is applied. Thereafter, the temperature Tf of the heat roller is detected again, and if the temperature Tf is above a predetermined temperature Ts at which the sheet is fed, the solenoid clutch is switched on to feed the sheet. If the print operation is not terminated, the temperature of the heat roller is detected again, and it is checked whether the temperature of the heat roller is above a predetermined fixing temperature Tp.
Abstract:
An emulsifying epoxy resin composition having excellent emulsifiability and storage stability, which comprises a specific epoxy resin (I), an emulsifiable epoxy compound (II) prepared by reacting an urethane compound (II-1), prepared by the reaction of a polyalkylene polyether polyol compound (II-1-1) having a number average molecular weight of 200 to 12,000 and an ethylene oxide content of 80% by weight or above with an excess amount of a polyisocyanate compound (II-1-2), with a specific epoxy compound (II-2) and an alkylphenol ethoxylate (II-3) having a number average molecular weight of 300 to 5,000 at a specific ratio, and water (III). A curable composition having a high cure rate and the cured product obtained these from having excellent film strength, water resistance and so on, which comprises the above-described emulsifiable epoxy resin composition and an active organic amino compound (IV) is also within the scope of the present invention.
Abstract:
A printer with a paper supplying device having a printing section that includes a photosensitive drum for printing on a paper, a manual supplying path for guiding a paper inserted manually, a manual insertion tray for receiving a paper in order to insert the paper into the printing section through the manual supplying path, a manual supplying means for supplying the paper from the insertion member to a printing section through the manual supplying path, an automatic supplying path for guiding a paper inserted automatically, a paper cassette for storing plural papers, an automatic insertion means for supplying a paper from the paper cassette to the printing section through the automatic supplying path, a manual insertion paper detecting sensor for detecting whether or not the paper inserted from the manual insertion tray is in the manual supplying path, an automatic insertion paper detection sensor for detecting whether or not the paper supplied from the paper cassette is in the automatic insertion path, and a LED for informing the operator of the time when the insertion member may receive a following sheet of paper. The LED is activated when no paper is detected by both the manual insertion paper detecting sensor and the automatic insertion paper detection sensor. An automatic insertion controller controls supply of the paper from the paper cassette to the automatic supplying path if there is no paper on the manual insertion tray when the printing of the paper previously inserted from either of the manual insertion tray and the paper cassette has been processed and the LED indicated such to the operator, and a manual insertion controller controls supply of the paper from the manual insertion tray to the manual supplying path if there is a paper on the manual insertion tray when a paper previously inserted from either of the manual insertion tray and the paper cassette has been processed and the paper cassette has been processed and operator informed by means of LED.
Abstract:
A fixing apparatus is provided with a light heater for heating a heat-fixing roller and a temperature detection element for determining the surface temperature of the fixing roller. A temperature corresponding to a lighting time for the heater is determined and compared with the temperature on the surface of the roller and the result of the comparison is used to turn the heater on and off.
Abstract:
A recording apparatus including a recording device for recording line of images on a recording medium, and a feeding device having a stepping motor for feeding the recording medium in a feeding direction perpendicular to the recording lines. The apparatus has a signal generator for generating a timing pulse in timed relation with the start of recording of each recording line so that the recording of each line is started in response to the timing pulse. Further, the stepping motor is stepped to feed the recording medium from one line to another, in response to the timing pulse, such that the stepping of the motor from one excitation phase to the next produces an incremental feeding distance of the medium which is equal to 1/n of a line spacing of the recording lines, where n represents a positive natural number.
Abstract:
Disclosed is a fixing apparatus wherein a print medium having an image transferred thereto is conveyed by rollers provided with a heat source, whereby the transferred image is fixed to the print medium. At least one of the fixing rollers has a hollow section in which the heat source is disposed toward the side at which the print medium is held and upstream with regard to the direction of rotation of the roller. The fixing apparatus comprises a detector for detecting the temperature at or in the vicinity of the heat source; an operating circuit for operating the heat source when the detected temperature is lower than a required temperature; a device for notifying an operator that the temperature of the fixing apparatus has reached a temperature required for the fixing operation; and a timer which starts to count from the start of operation of the heat source. When the required temperature is reached, the timer is reset, and when operation of the heat source is restarted, the timer starts to count again. The notification by the notifying device is continued regardless of the temperature, and is stopped when the count of the timer reaches a predetermined value.
Abstract:
A method of maintaining the load bearing integrity of a pre-existing reinforced concrete post during earthquake tremors wherein a sheet metal band is placed about the post and then made integral thereto by inserting a hardenable bonding agent between the band and the post.
