Abstract: PURPOSE:To improve the paper discharging property of the titled copying machine and, at the same time, to prevent its heating roll from being scratched so as to sharply extend its usable life, by forming a separation click of a synthetic resin and covering at least a part of the surface with a metallic thin film. CONSTITUTION:It is preferable to use a synthetic polymer having a melting point of >=200 deg.C as the synthetic resin for constituting the base section 1 of a separation click, especially in the case of the separation click to be used for a high-temperature heating roll. The full surface of the base section 1 made of such synthetic resin is covered with a metallic film 2, but a case of the metallic film 2 covers only the roll contacting surface in the vicinity of its edge 3 also happens. A photosensitive drum 4 is charged by an electrifier 5 and the separation click 6 is contacted with the photosensitive drum 4. Since the separation click 6 becomes a conductor due to the metallic film 2, the click 6 is not charged. Copying paper 7 is fed after heat-fixing by a fixing roll 8 and press roll 9. The separation click 6 is contacted with the fixing roll 8 on the copying paper discharging side and the copying paper 7 separated from the fixing roll 8 advances while being contacted with the click 6.

Title: Radiosensitive compound and formation of pattern using same
Inventor: UCHINO MASAICHI
IPC: H01B13/00
Filed: 1990-10-30
Abstract: PURPOSE:To realize provision of radiosensitive compound excellent in heat stability, and having high sensitivity and high resolution by allowing alkaline soluble polymer compound and carbon directly coupled to aromatic ring to include secondary or tertiary alcohol having hydroxyl group and precursor acid generating acid by application of radiation. CONSTITUTION:Secondary or tertiary alcohol having hydroxyl group and precursor acid generating acid by application of radiation are included in alkaline soluble polymer compound and carbon directly coupled to aromatic ring. The secondary or tertiary alcohol having hydroxyl group in the carbon directly coupled to the contained aromatic ring effectively takes dehydrating action when it is heated under strong acid to generate lipophilic compound. Since the hydrating action is induced by the acid generated from the precursor acid in a radiation application range when heating is carried out especially after application of radiation, unsoluble or slightly soluble characteristic to alkaline developing liquid is obtained. This radiosensitive compound serves as a negative type photosensitive compound. It is thus possible to have excellent sensitivity and stability against ultraviolet ray, electron beam, another radiation.

Title: Production of tetraalkylbisphenols and production of bisphenols
Inventor: KITAMURA TAKU
IPC: C07B61/00
Filed: 1990-10-29
Abstract: PURPOSE:To obtain the subject tetraalkylbisphenol by carrying out a disproportionation reaction between a tetraalkyldiphenoquinone and a dialkylphenol using, as a solvent, a phenol except the above-mentioned dialkylphenol. CONSTITUTION:A tetraalkylbisphenol is produced by disproportionation reaction between (A) a tetraalkyldiphenoquinone and (B) a dialkylphenol in (C) a phenol (e.g. phenol or monoalkylphenol) except the component (B) as a solvent at 150-200 deg.C. The alkyl groups are then eliminated from the resultant tetraalkylbisphenol in the same reaction system without isolation of the tetraalakylbisphenol to produce a bisphenol. The alkyl group elimination reaction is carried out by heating in the presence of an acid catalyst. Since the disproportionation reaction temperature can be lowered, the purity of the objective compound can be improved. No later recovery process is required because the component (B) of more than the stoichiometric amount is not required.
