摘要:
A thermal fixing device including a pair of rotating rollers which are press-contacted to each other, a heating section associated with at least one of the rollers and an image supporter having an unfixed toner image which is passed through a gap between the rollers so that the unfixed toner image is thermally (melt) fixed, the heating section having an integral structure type heating and cooling device which includes a cooler and a heater acting as a support, and wherein the fixing device further includes a thin endless metal belt which rotates while contacting the integral structure type device and which has a non-adhesive film on the outer surface of the belt, and a drive roller which drives the endless metal belt for rotation while applying tension to the endless metal belt. The surface temperature at a portion where the endless metal belt is in pressure-contact with the image supporter is first increased to a temperature (Tm) near the melting point of the toner and then cooled so that the image supporter can be stripped prior to the endless metal belt, and so that the temperature is higher than the glass transition point of the toner and lower than the softening point of the toner.

A process for preparing a cordierite, which includes dissolving a silicon compound, an aluminum compound and a magnesium compound in a molar ratio of 1:0.7 to 1:0.3 to 0.5 in a complexing agent represented by the formula R(OCH.sub.2 CH.sub.2).sub.n OH, wherein R is an alkyl group and n is an integer of 1 to 4; heating the resulting solution to bring about a ligand exchange reaction of the silicon compound, aluminum compound and magnesium compound with the complexing agent; conducting hydrolysis to form a gel; drying the gel and sintering the dried gel at 800.degree. to 1450.degree. C.

A coin receiving apparatus for a vending machine is disclosed which has a coin detector for producing an output corresponding to the diameter of a deposited coin. One or more additional coin detectors of a differential transformer type are sequentially arranged adjacent to the coin diameter detector in the coin detection path for producing an output corresponding to coin characteristics other than the coin diameter. A coin determination circuit judges whether the deposited coin is true or false in response to the detected outputs from the respective coin detectors. A coin receipt control circuit responsive to the true or false judgement output from the coin determination circuit controls the receipt or return of the deposited coin. The deposited coin is received in the receiving apparatus if the detected outputs from all of the coin detectors indicate that the deposited coin is true. A successive deposit determination circuit judges whether the last deposited coin passes through an initial coin detector on the coin detection path before the preceding deposited coin passes through a final coin detector. A timer starts to operate when the deposited coin passes through the final coin detector and responsive to an output of the successive deposit determination circuit. A determination output control circuit applies the true judgement output from the coin determination circuit to the coin receipt control circuit only when the timer does not operate after the deposited coin passes through the final coin detector. The coin receiving apparatus having such a successive deposit determination circuit, timer and determination output control circuit reduces the coin return ratio.

Rapidly curable adhesive compositions suitable for bonding polypropylene, comprising a polymer of sulfochlorinated and/or chlorinated polypropylene with an average chlorine content of 26% to 34% by weight, and an average molecular weight of 5,000 to 120,000, dissolved in monomeric ingredients such as acrylic and/or methacrylic monomers.
摘要:
A mechanical pencil including a main body divided into first and second members which are rotatable relative to one another. An inner mechanism is provided, primarily in the first member of the body, including a chuck for gripping leads, a chuck tightening member for tightening the chuck disposed around the chuck, a chuck tightening member receiver, and a lead case coupled at a front end portion to the chuck. In a preferred embodiment, a push member is coupled at a front end to the lead case while a spring biases the inner mechanism rearwardly. A mechanism is provided for converting the relative rotation of the first and second members to axial movement of the inner mechanism between retracted and writing positions.
摘要:
The invention provides an efficient method for the preparation of ethylbenzene by the reaction of toluene and methyl alcohol. By virtue of the specific active ingredients contained in the catalyst, the catalyst is free from the problem of rapid decrease of the catalytic activity owing to coking so that the inventive method is very satisfactory as an industrial process for the preparation of ethylbenzene.
