IPC: C01G23/00
Filed: 1992-02-17
Abstract: PURPOSE:To make fine particles of titanium oxide hydrophobic without damaging powder properties by dispersing fine particles of titanium oxide into an alkali aqueous solution, adding a trialkoxysilane thereto and hydrolyzing. CONSTITUTION:1-60 pts.wt. fine particles of titanium oxide having 0.001-200mum particle diameter are dispersed into 100 pts.wt. alkali aqueous solution (e.g. ammonia) having pH10.0-13.0 and 1-1,000 pts.wt. trialkoxysilane (e.g. trimethoxysilane) of the formula R<1>Si(OR2)3 (R<1> is 1-6C alkyl, aryl, alkenyl, monofunctional organic group containing one or more of amino group, epoxy group and vinyl group or organic group containing one or more of these groups substituted with halogen; R<2> is 1-6C alkyl) are added little by litte the dispersion at 0-60 deg.C while stirring to carry out hydrolysis condensation reaction. After the reaction is over, the resulting substance is optionally washed with water and dried. The fine particles of titanium oxide have a coating film with such a sufficient thickness and chemical bond strength as to show hydrophobic nature on the surface and have excellent water repellency and dispersibility to organic resin materials.

Title: Manufacture of low-permeability hose
Inventor: FUJIO KATSUYOSHI
IPC: B29C48/06
Filed: 1990-03-14
Abstract: PURPOSE:To remove easily a core by making mold release properties between a mandrel and resin layer excellent at the time of removal of the core, by a method wherein prior to extrusion coating of molten resin over a surface layer of the mandrel made of rubber which is provided with a mold release layer comprised of fluorine rubber, a silicone mold release agent having specific viscosity is applied to the surface layer of the mandrel. CONSTITUTION:When a mandrel 2 is sent out by a sending-out machine 1, a mold release agent is applied to the surface of the mandrel 2 by an applicator 3 of the mold release agent. The mold release agent is of a silicone mold release agent having viscosity of 300cs=1,000cs and mold release properties are improved by combined use of a mold release layer 2c formed on a surface layer of the mandrel 2 and the silicone mold release agent. At the time when the mandrel 2 passes through an extruding machine 4, a resin layer 7 is formed over the mandrel 2 and wound up once around a wind-up drum 6. Then shifted to a core removing process by passing through a process identical with conventional one. Although the removal of the core is performed by applying water pressure to a space between the mandrel 2 and resin layer 7, the mandrel 2 can be removed easily at favorable mold release properties by the mold release layer 2c and silicone mold release agent and it is not feared that the inside of the resin layer 7 is hurt.

Title: Integrated circuit
Inventor: KOMATSU HIDETOSHI
IPC: H03F1/30
Filed: 1978-05-23
Abstract: PURPOSE:To ensure an effective application of the integrated circuit to the hearing aid, the microminiature radio and others by forming the feedback elements of the voltage and output amplifying  steps with the resistance comprising the MOSFET and also securing the temperature compensation by utilizing the difference of the temperature characteristics between the output transistor and  the feedback element. CONSTITUTION:Voltage amplifying steps 31 and 32 comprising the MOSFET of C.MOS structure drive power amplifying step 33 consisting of bipolar transistor Tr. At the same time, feedback element 34 comprising the resistance composed of the MOSFET applies the feedback between the input and output to perform setting of the amplification factor and the necessary frequency characteristics. The drain current of the MOSFET shows the negative temperature  characteristics, and the collector current of output Tr33 features the positive temperature characteristics each. Thus, the failure such as the thermal runaway and the like are liable to occur.  Utilizing the difference of these temperature characteristics, Tr33 and element 34 are distributed  close to each other within the chip. As a result, the resistance value of element 34 reduces by the  increment of the junction temperature of Tr33 to lower the amplification factor. Accordingly, the  drive voltage of the output step is lowered down to perform the temperature compensation.

CONSTITUTION:Steel strip 22 having passed through molten Zn contained in a plating pot 21 proceeds between gas jets 23, where deposited Zn is adjusted. Then the strip 22 is heated in a direct flame type heating zone 14 equipped with gas burners 15 and maintained at a hot state in a convection heating zone 16 installed above the heating zone 14 thereby alloying the plated Zn with the steel strip 22. The convection heating zone 16 is composed of a movable section consisting of a wind box 18 and spraying nozzles 19, and a fixed section consisting of a wind box 18' and spraying nozzles 19', both sections being heated by use of high-temp. combustion gas produced in the direct flame type heating zone 14. In alloying of the plated surface, both movable and fixed sections are used for heating and maintaining the strip at a hot state, and in ordinary plating process, the wind box 18' of the fixed section is used for cooling plated strip. Hence a cooler 32 is unnecessary, and the height of a cooling tower to a deflector roll 39 is decreased.

Abstract: PURPOSE:To improve solubility of a core substance and ensure stability of color forming properties with time, by using a specified compound as a core substance component, in a pressue-sensitive recording sheet utilizing a color reaction based on formation of a complex of a ligand compound with an iron (III) compound. CONSTITUTION:An amide compound of formula I or II is incorporated as a capsule core substance, in a pressure-sensitive recording sheet comprising a combination of microcapsules containing an alkyl gallate (the total number of carbon atoms in an alkyl group is at least 12) with an iron (III) compound.

Ordinarily, the amount of the amide compound is preferably 1-95pts.wt. per 100pts.wt. of the capsule core substance. The use of the amide compound makes the alkyl gallate more liable to be dissolved in an oil, restrains the alkyl gallate from crystallizing in capsules, and enables color forming properties to be favorably maintained with time. In the formulas, each of R1-R5 is satd. or unsatd. substd. or unsubstd. alkyl.
