Title: Descaling agent
Inventor: KATO ISAO
IPC: C02F5/00
Filed: 1986-04-11
Abstract: PURPOSE:To efficiently dissolve and remove scales consisting essentially of anthraquinone and/or its compd. by using the titled descaling agent contg. an alkaline substance, a reducing substance, a hydrocarbonic solvent, and a surfactant. CONSTITUTION:An alkaline substance (e.g., sodium hydroxide), a reducing substance (e.g., sodium hydrosulfite), a hydrocarbonic solvent (e.g., an aromatic hydrocarbonic solvent), and a surfactant (e.g., a nonionic surfactant) are incorporated in the agent. The scale removing efficiency can be remarkably improved by the descaling agent thus obtained as compared with the conventional descaling agent consisting of the above-mentioned essential components other than the hydrocarbonic solvent. The scales consisting essentially of anthraquinone or the like deposited on the inside of a black liquor concentrating device in a kraft pulp making factory can be collapsed and stripped off by the agent, the scales are further dissolved, and removed, and the heating efficiency and operation rate can be remarkably improved.

Title: Dividing device
Inventor: TOYOSHIMA NARIHISA
IPC: G06G7/16
Filed: 1980-06-17
Abstract: PURPOSE:To facilitate an easy designing of a circuit that processes the bipolar signal without using any special circuit, by providing a rectifying circuit and a limiter at the denominator input side of an analog dividing circuit and thus securing an accurate operation regardless of the polarity (positive or negative) of the denominator input signal. CONSTITUTION:An inverse amplifier 20 is connected to a numerator input terminal 17 of an analog dividing circuit 10, and the numerator input data beta is applied to an input terminal 21a of the amplifier 20. At the same time, an arithmetic circuit 22 is connected to a denominator input terminal 16 to process the denominator input data alpha given from an input terminal 21b. Then the data alpha is rectified by a rectifying circuit 30, and the code is inverted to the negative polarity through a code converter 40 that supplies the output of the circuit 30. Then the input to a code converter 60 of the next stage is limited to a prescribed value by a limiter 50 when the data alpha is zero or near zero. After this, the code is inverted to the postive polarity by the converter 60 to be applied to the terminal 16. Thus an accurate operation is possible regardless of the polarity (positive or negative) of the data alpha.
