Title: Water treating device
Inventor: MAEDA SADAO
IPC: C02F1/28
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To improve the safety against bacteria by sterilizing the bacteria contained in such water as city water. SOLUTION: The water injected into a filter 6 from an injection port 7 passes through the filter bed consisting of the Triosin (trade name of Hydro Biotech corp., Canada for a kind of an ion-exchange resin) bed 11, stand bed 12, activated-carbon bed 13, granite porphysy bed 15, first magnetite bed 16, ceramic bed 17, second magnetite bed 18 and other bed 14 and then discharged from a water discharge port 8. When the bacteria, etc., approach the surface of a triosin resin in the Triosin bed 11,a power to exchange for iodine ion is exerted, hence the iodine ion is released, and the bacteria coming in contact with the Triosin surface are sterilized by the oxidizing action of iodine. Further, since the Triosin resin releases iodine in the amt. corresponding to the bacteria, an excess of iodine is not released, and the treated water (filtered water) is never contaminated. Accordingly, bacteria are sterilized, and the water freed from the bacterial toxin is supplied as drinking water, etc.

Title: Device for preventing foreign matter from entering into fluid chamber of probe
Inventor: SVEN BERGSTOEL
IPC: A61B8/12
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent foreign matter from entering into an acoustic fluid chamber by opening and communicating the first end part of a tube with a fluid chamber, opening and communicating the second end part of the tube with atmospheric pressure and making the dimension of the tube possible to be operated in an aggressive operation. SOLUTION: An acoustic fluid 112 from an acoustic chamber 110 connected through an orifice is expanded and contracted through the orifice by a capillary 114 which is opened and fluid-communicated with the acoustic fluid 112 included in the acoustic chamber 110. The acoustic fluid 112 inside the acoustic chamber 110 is expanded and contracted inside the capillary 114 through the orifice and comparatively stable inner pressure is kept in the acoustic chamber 110. The dimension of the capillary 114 is made to be the one for an aggresive operation. For example, the dimension of the tube 114 is made to be small as compared with a convetional type capillary to be used in a ultrasonic wave probe. As a result, the usage possibility by the probe against the aggresive operation is enhanced.

Abstract: PROBLEM TO BE SOLVED: To provide a measuring method, for a partial discharge, in which a skilled measuring operator is not required, in which the partial discharge can be judged simply and with high judgment accuracy and whose reliability is high. SOLUTION: The magnitude (q) of a discharged electric-charge amount in every cycle (t) obtained by a partial discharge detector attached to a power cable and information on a generation phase angle ϕ are arranged in a time- series manner, and three-dimensional ϕ-q-t data by which the magnitude of the electric charge amount of a measuring signal with reference to an electricity- application phase and the generation phase angle are indicated is created. Then, the electricity-application angle, the number of electricity-application cycles and the discharged electric-charge amount axis of the ϕ-q-t data are divided, and a ϕ-q-t pattern is created. Then, the ϕ-q-t pattern is input to a neural network Nu1 in which the ϕ-q-t pattern of a partial discharge signal is learned in advance, and the existence of the partial discharge signal is judged. In addition, ϕ-q-n data [where (n) represents the number of occurrences] is sorted into groups, a partial discharge is judged by using a sorted result, and the partial discharge can be measured with high accuracy in the same manner.

Title: Prevention system for reconstitution function stop of constitution controller
Inventor: MATSUURA FUMIAKI
IPC: H04L12/437
Filed: 1990-09-05
Abstract: PURPOSE:To improve the reliability of a ring-like LAN system by preventing a constitution controller from stopping a reconstitution function when a system starts. CONSTITUTION:When a reconstitution operation counter 8 and a reconstitution operation supervisory timer 9 receive an operation start instruction from a reconstitution control mechanism 11, they start respective operations. When the reconstitution control mechanism 11 detects that reconstitution operation is executed more than the number of prescribed times within prescribed time, it can stop the reconstitution function. Thus, a function stopping the reconstitution function is prevented from operating within prescribed time after the rise of the reconstitution controller 1, namely, after the system starts by the reconstitution control mechanism 11. The stop of the reconstitution function of the constitution controller owing to the temporary excess of the specified value of a transmission line length when the system starts can be prevented and the reliability of the transmission system can be improved in a transmission system such as ring-like LAN having duplexed ring-like transmission line.

IPC: G06F13/374
Filed: 1991-08-22
Abstract: PURPOSE: To provide an improved bus arbitration system which can reduce the delay of an arbitration cycle. CONSTITUTION: It is judged whether only one communication module 14 competes for a communication data bus based on a single competitive module arbitration code. If judged so, an access is given to the module 14 within a double bus clock cycle. An integrated code is generated by means of the true and complement of a module ID. The check code of every bit is decided by addition of the integrated code of a bit and that of its adjacent one. If a check code includes 0, it is decided that two or more modules compete for the data bus. The errors can be detected and corrected on a 32-bit data bus via a 10-bit single arbitration mechanism.

Title: High frequency power control system
Inventor: TANAKA HIROTADA
IPC: H03G3/30
Filed: 1987-09-18
Abstract: PURPOSE:To expand the variable range of level control by using two coupling circuits having different degrees of coupling and two detecting circuits to obtain two detecting voltages and switching the two detecting outputs in accordance with a level for controlling an output signal. CONSTITUTION:The degree of coupling of the coupling circuit 2 is set up so as to be slightly lower than the lower limit of a level to control an output signal SO. On the other hand, the degree of coupling of the coupling circuit 3 is set up so that a detecting voltage VD2 is almost equal to a detecting voltage VD1 at a level PC2 in which the voltage VD2 is not sharply changed even if the level of the output signal SO is changed. When the level to control the output signal SO is about the level PC2 or lower than it, a switching signal CS1 allows a change-over switch 6 to select the detecting voltage Vs1. When said level is larger than the level PC2, the switch 6 is allowed to select the detecting voltage VS2. Consequently, a detecting voltage to be inputted to a comparator can be reduced over the whole range of level control.
