Title: Water-based ink composition
Inventor: MURAKAMI KAKUJI
IPC: C09D11/02
Filed: 1986-08-15
Abstract: PURPOSE:To enable the stabilization of printing operation after prolonged stoppage of the printing particularly with an ink jet printer, by incorporating a specified quaternary phosphonium ion into a water-base ink composition used as, e.g., a writing ink, a printing ink or a stamping ink. CONSTITUTION:This water-based ink composition contains a quaternary phosphonium ion of formula I (wherein R1-R4 are each a substituted or unsubstituted alkyl group, or a substituted or unsubstituted phenyl group). Examples of the quaternary phosphonium ions include those of formulas II, III, and IV. It is most desirable that a phosphonium ion be incorporated into this ink composition as a pH modifier comprising phosphonium hydroxide or phosphonium carbonate, or as a counter ion of a dye containing acid groups of, e.g., a sulfonic acid or a carboxylic acid.

Title: Automatic switching device for water feeding pump
Inventor: INAHASHI KAZUMICHI
IPC: F22D5/34
Filed: 1988-08-03
Abstract: PURPOSE:To enable automatic switching of a feed pump in a short time in a state that a fluctuation in a flow rate of feed is suppressed to a minimum by a method wherein a switching change factor is corrected according to a feed flow rate deviation between an increase amount of water fed with the aid of a turbine-driven feed pump and a decrease amount of water fed with the aid of a motor-driven feed pump. CONSTITUTION:A deviation between an actual feed flow rate signal 20 and a feed demand set signal 21 from a boiler master system is determined by an adder 25, and a proportional and integrating computation is effected by a feed controller 26 to determine a flow rate demand value. In the case of a turbine-driven feed pump, a deviation between a flow rate demand value and a pump outlet flow rate (check valve flow rate) signal 27 is determined by an adder 28, and proportional and integrating computation is effected by a flow rate control device 29. This controller output is inputted to a turbine controller 30. An output from the turbine controller 30 is provided as a signal by means of which a steam regulating valve 32 to control a flow rate of low pressure steam extracted from a main turbine 3 is opened and closed, and the number of revolutions of a turbine 31 for driving a feed pump is controlled. Meanwhile, in the case of a motor-driven feed pump, a feed regulating valve 9 is directly controlled by a means of an output from a flow rate controller 33.

IPC: G06F12/00
Filed: 1988-08-02
Abstract: PURPOSE:To execute retrieval at a high speed by changing store blocks of the same level in an index file by a block pointer. CONSTITUTION:A pointer maintaining means 5 maintains a pointer for connecting store blocks of the same level in an index file 1, when a new store block has been increased in the index file 1 by a record store means 3. A block searching means 6 uses the pointer and searches the store blocks of the same level in the index file 1. A record selecting means 7 starts the block searching means 6, when an index record for satisfying a retrieval condition comes not to exist and allows it to search the store blocks before and behind the same level and selects the index record for satisfying the retrieval condition. An index retrieving means 8 inputs the retrieval condition, starts the record selecting means 7 and extracts a pointer from the index record which has been selected. In such a way, the retrieval can be executed at a high speed.

In the next step, absorbancies of the main wavelength 545nm and a sub-wavelength 600nm generated by reaction are respectively measured in a spectrophotometer 14 and, from the difference calculated by subtracting the absorbancy of the sub-wavelength from that of the main wavelength, the concn. of the total protein is calculated from a calibration curve preliminarily calculated from a known concn. specimen. In this case, red coloring matter such as amaranth or erhthrocin is added to a reagent along with a cupric salt and a tartrate in such an amount that the absorbancy of the main wavelength becomes 0-1 higher per a light path length 10mm. than that of the sub-wavelength. By this method, the error due to the apparent change of absorbancy is eliminated and accurate analysis is performed.

Title: Temp. control method of furnace
Inventor: HASHIMOTO YOSHIYUKI
IPC: F23N5/00
Filed: 1985-09-02
Abstract: PURPOSE:To improve energy saving feature, operability of a furnace, and temp. distribution in the furnace by switching operation to a proportional control in a high burning and to an on-off control in a low burning range. CONSTITUTION:During a high burning time, the burning amount is continuously changed using such an advantage of a proportional control that fuel to air ratio is kept at a constant level and energy saving and temp. distribution properties are excellent as wee. On the other hand, during a low burning time, an on-off operation is carried out under the condition which throttles the amount of fuel and air together. Without stopping some of the burners and introducing excess air, the temp. range between the upper and lower limits is kept small as compared with an conventional on-off operation with improved temp. distribution during this operation. Switching temp. from the proportional to the on-off operation is determined by measuring the furnace inside temp. distribution. And, operation may be switched over automatically at an appropriate switching temp.
