Abstract: A method for forming a metal pattern by the micro-stamping process involves the steps of treating a substrate bearing a thin film of a reducing silicon polymer with a solution containing a salt of a metal having a standard oxidation-reduction potential of at least 0.54 volt, allowing metal colloid to deposit on the substrate surface, stamping a pattern of an alkane thiol to the substrate surface for transferring the pattern to the metal colloid-bearing silicon polymer thin film, and effecting electroless metal plating for forming a metal pattern only on the region of the silicon polymer thin film which is not covered with the alkane thiol pattern. The finely defined metal pattern can be formed on any type of substrate though inexpensive simple steps and has good adhesion to the substrate.

Abstract: Around a heat roller, a center thermistor (20c) as a first temperature sensor is placed within the range of ±450 from a portion where maximum heat is generated by an IH coil, and a front thermistor (20f) as a second temperature sensor is placed within the range of ±45° from a portion where minimum heat is generated by the IH coil. A main CPU (201) performs fixing control on the basis of sensing temperatures from these two thermistors (20c, 20f). This can prevent an increase in the cost and uniformize the heat distribution of a fixing roller.

Abstract: An organopolysiloxane composition for molding purposes is provided which includes: (A) an organopolysiloxane with at least two alkenyl groups bonded to silicon atoms, (B) a straight chain organopolysiloxane with a hydrogen atom bonded to a silicon atom at both terminals, (C) an organohydrogenpolysiloxane with at least three hydrogen atoms bonded to silicon atoms within a single molecule and including a RHSiO unit and a R2XSiO1/2 unit (wherein R is an unsubstituted or a substituted monovalent hydrocarbon group with no alkenyl groups, and X represents either a hydrogen atom or a group represented by R as defined above) within the molecule, (D) a hydrosilylation reaction catalyst, and (E) finely powdered silica, wherein the total number of hydrogen atoms bonded to silicon atoms within the constituent (B) and the constituent (C) ranges from 1 to 5 per alkenyl group within the constituent (A), and the number of hydrogen atoms bonded to silicon atoms within the constituent (B) accounts for 20 to 70 mol % of the com

Abstract: A room temperature curable organopolysiloxane composition comprising (1) a hydroxyl end-blocked organopolysiloxane having a viscosity of 10-1,000,000 centistokes at 25° C. in admixture with a premix of (2) methyltriacetoxysilane or a partial hydrolyzate thereof as a curing agent and (3) methanol is improved in shelf stability, physical properties and outer appearance as well as adhesion to aluminum.

Abstract: This invention is made to prevent the user from re-setting paper by effecting a process for pushing a sheave of sheets of paper by a transferring guide towards the paper feeding side if setting of paper of a tandem type LCF is not correctly effected and when it is predicted that it is structurally safe based on information of an end guide switch and no-paper-on-the-wait-side switch. Thus, useless time and labor of the user can be alleviated and the reliability as a device can be enhanced by effecting the transferring process which is structurally safe.

Abstract: A liquid silicone rubber base including (A) an alkenyl-containing organopolysiloxane, (B) a reinforcing silica filler, (C) a mixing assistant in the form of a silanol-containing compound, (E) an organohydrogen polysiloxane, (f) a platinum catalyst and optionally, (D) a wetting auxiliary catalyst is prepared by previously mixing 10-120 parts of component (A) with 1-35 parts of component (C) and 0-35 parts of component (D) to form a premix liquid, mixing the premix liquid with 100 parts of component (B) to form a premix power, and kneading the premix powder with the remainder of component (A). By adding a curing agent of organohydrogenpolysiloxane/platinum catalyst to the liquid silicone rubber base, there is obtained a liquid silicone rubber composition having improved fatigue endurance.

Abstract: An addition-curable type silicone rubber composition comprising (A) an organopolysiloxane having an alkenyl group such as vinyl in its molecule, (B) an organohydrogenpolysiloxane having at least two SiH groups in its molecule, (C) a platinum catalyst such as platinum, chloroplatinic acid, etc., (D) an inorganic filler, (E) an organic titanium compound such as tetraethyl titanate, and (F) water. The composition exhibits good fluidity, and behaves like a Newtonian fluid, even where carbon black or a silica or alumina having an average particle diameter of 1 .mu.m or above is incorporated in the composition as an inorganic filler for improving such characteristics as heat resistance, thermal conductivity, etc.
