Title: Analysis of anion using complex forming reaction
Inventor: MIYANAGA AKIYOSHI
IPC: G01N30/02
Filed: 1987-02-27
Abstract: PURPOSE:To achieve a better sensitivity, by measuring electric conductivity through a complex forming reaction support bonded to a transition metal ions after the separation of anions by an eluate containing aminodicarborate using an anion exchange resin column. CONSTITUTION:An eluate containing alkaline metal or a alkaline earth metal salt of aminodicarbonic acid is fed with a liquid feed pump from an eluate tank to inject a fixed amount of a sample with a sample liquid injector and then sent to a separation column filled with an anion exchange resin set in a thermostatic tank. Then, after being passed through a complex forming reaction support to which transition metal ions previously ion bonded, the mixture is introduced to an are electric conductivity detector and a detection signal is displayed on a recorder as chromatogram. This allows a lower value of the electric conductivity of the eluate itself as well as a highly sensitive measurement of anions in the sample.

IPC: G02F1/17
Filed: 1983-03-15
Abstract: PURPOSE:To form a stable functional thin film by freezing temporarily water to be introduced before vapor deposition or sputtering when water is introduced in a thin film, and melting the frozen water and introducing it into a vacuum tank during vapor deposition. CONSTITUTION:An H2O supply cylinder 11 is detached from a joint 16 and inserted into a container filled with a freezing mixture to cool and solidify the H2O in the cylinder 11. The container 12 filled with the freezing mixture is connected to the side of the vacuum tank 1 as it is after the H2O in the cylinder 11 is solidified completely, and a valve 9 and a stop valve 10 are opened fully to evacuate the vacuum tank 1. No H2O vaporizes in said state and the oxygen dissolved in the H2 is removed. The H2 in the cylinder 11 is melted and then controllers 14 and 14' are set to constant temperatures above 0 deg.C. The vapor pressure of pure H2O is controlled only by controlling a leak valve 9 during vapor deposition or sputtering to perform the vapor deposition or sputtering.

Title: Repairing procedure for block lining
Inventor: UEHARA GIICHI
IPC: F23J13/02
Filed: 1983-03-15
Abstract: PURPOSE:To allow for the repairing of cracked area of block lining exclusively without the need to remove the whole block lining in question, by employing a procedure of removing merely the cracked area of block lining after a coring operation. CONSTITUTION:Shallow coring holes are bored by means of a coring drill through a crack 8 spreading over a plurality of blocks 1, the coring holes being overlapped each other. In repairing, the cracked areas are grouped into an odd numbered group and an even numbered group which lie alternately, and one of these two groups is repaired first. After a joint filler is dried over this repaired area, the repairing of another cracked group is started. Specifically, for example, the odd numbered group including cracked areas No. 1, 3, 5 and 7 is cut off first together with a lining material to remove a cylindrical coring by means of a coring drill 9 and then a new block core 1B which has been pre-molded with a slightly small diameter through a coring procedure is inserted into the core hole after a joint filler 2A is applied thereon. After the joint of this group is cured, a similar procedure is taken also for the even numbered group including the cracked areas No. 2, 4, 6 and 8. A joint trimming finish can complete the repairing.

Abstract: PURPOSE:To design a filter in a short time by reading a design object designated from a 1st file, selecting an optimum board satisfying the object from a 2nd file and designing the filter according to a 3rd file. CONSTITUTION:When an input device 15 selects and designates a design object, a processor a 16 reads the design object designated from a 1st file 11 and makes a rough design according to the design procedure stored in a 3rd file 13 to check the design probability.

When it is judged that the object is not satisfied, the process is restored back and the filter is designed again, and when it is judged that the object is satisfied, the result of design is displayed on a display device 17. The design content is confirmed based on the display of the display device 17, and when print-out is designated through the device 15, the processor 16 sends the result of design to an X-Y plotter 18, on which the content is printed out. Thus, the filter is designed equally by a skilled or unskilled person.

Title: Spread spectrum receiver
Inventor: ISHIGURO KAZUHISA
IPC: H04B1/707
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To conduct accurate inverse spread spectrum processing by detecting a correlation output between a spread code and a spread spectrum signal so as to take synchronization between the spread code and the spread spectrum signal depending on the result of detection thereby synchronizing the spread code of a transmitter side with the spread code of a receiver side. SOLUTION: A correlation detection circuit 15 detects the correlation between a received spread code and a spread spectrum signal. Then a control circuit 16 discriminates whether a phase of the spread code is delayed from or advanced from a phase of the spread spectrum signal based on the detected correlation output and generates a switching control signal and a lead or delay control signal depending on the result of discrimination. Then a frequency division ratio of a frequency divider circuit 11 is selected depending on the lead or lag control signal. The spread code synchronously with the spread code in the spread spectrum signal is generated and the spread code and the spread spectrum signal are multiplied by a 1st multiplier 2 in this way, then accurate inverse spread processing is executed.

Title: Power circuit
Inventor: NAKANO KENJI
IPC: H02M3/155
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To improve a power converting efficiency in driving a small load, and extend the life of a battery when driving loads of different sizes. SOLUTION: When driving a normal load 11, a switch 16 is turned off and therefore an inductance is increased since both o f inductors 2, 15 are in an on state, thereby decreasing inductor current iL. By the on/off operations of a switching device 3, an operation that the power accumulated in the inductors 2, 15 is discharged to an output capacitor 9 is repeated, thereby keeping the output voltage E in a specified range. When driving a maximum load 12, the switch 16 is turned on and therefore the inductance is small since only the inductor 2 is in an on state, thereby increasing the inductor current iL and charging power by the inductor 2.  Therefore, even if the load current iR becomes large because of the maximum load 12, the decrease in the output voltage E can be sufficiently compensated by the power accumulated in the inductor 2, and the output voltage E can be kept in the specified range.

Filed: 1994-02-18
Abstract: PURPOSE:To provide a blank for wind instruments which has a high hardness, is hardly softened even in the heat treatment at the time of working and is capable of maintaining a high grade by specifying the contents of one or two kinds of Ca and Si to be a specific ratio in total and consisting the balance with Au. CONSTITUTION:The hardness of the blank for the wind instruments is improved if one or two kinds of the Ca and Si are added at 0.01 to 1wt.% in total to Au. In such a case, the effect thereof is not expected if the content is below 0.01wt.%. The grade of the Au is reduced to <99wt.% if the content of Ca and Si exceeds 1wt.% and the effect is lowered. Namely, the hardness is improved and, therefore, deformation and permanent set in fatigue are hardly generated during handling. In addition, the blank is hardly softened in the heat treatment at the time of working and the high grade of Au is maintained. The molten meal flow at the time of casting is improved by he deoxidation effect of the Ca and Si and material defects, such as pinholes, are eliminated.
