Title: Method for electrolyzing iron
Inventor: SAWAZAKI TETSUO
IPC: C23F13/00
Filed: 1988-03-04
Abstract: PURPOSE:To prevent the clogging between electrodes and a decrease in the current density by stopping electrolysis for specified hours in the method wherein the electrolytic current density on the electrode is enhanced, and the polarity of the electrodes is changed at regular time intervals to generate iron ion in seawater. CONSTITUTION:Seawater is introduced into an electrolytic cell 5 from a seawater inlet 7, and discharged from a seawater outlet 7. The parallel electrodes 3 and 4 are vertically set at some distance in the cell 5, and connected to a power source through conductive rods 1 and 2. The density of the current flowing through the electrodes 3 and 4 is controlled to a high current density of >=4A/dm<2>, the polarity of the electrodes 3 and 4 is changed at regular time intervals, and electrolysis is stopped for a surplus time spent for holding a high current density. Iron ion is generated in the seawater in the cell 5, discharged from an outlet 6, and utilized for preventing the corrosion of the condenser tubes, etc., of a thermal power plant. The deposition of scales on the electrode is prevented by this method, and the cell can be operated under low- load conditions.

Title: High-vision 3-1 sound simple output device
IPC: H04S1/00
Filed: 1992-03-10
Abstract: PURPOSE:To remove a center speaker and simplify the whole constitution, and also improve presence by distributing a High-Vision 3-1 sound to a right and a left speaker as required according to whether or not surround speakers are provided by using a sound matrix. CONSTITUTION:As for the left and right signals L and R, center signal C, and surround signal S of the High-Vision 3-1 sound signal, the signals C and S are distributed together with the signals L and R and outputted from the left and right speakers 3 and 4 as signals L'6 and R' by the sound matrix 1 which respond to control pulses from a surround sound output terminal 5 with a switch unless the surround speakers are connected. When the surround speakers are connected, on the other hand, they are outputted from the surround speakers connected to the terminal 5 without being distributed to the left and right speakers. Consequently, the need for the center speaker is eliminated to simplify the constitution, and the presence is prevented from being spoilt when the left and right speakers and center speaker are put close to one another, and then improved.

Title: Gas discharge panel
Inventor: SATOU MORISHIGE
IPC: H01J11/28
Filed: 1978-04-27
Abstract: PURPOSE: To avoid the unnecessary discharge at the writing cell part for the self- shift type gas discharge panel by leading out in crossing the writing electrodes via the opposing part between the writing electrode and the bus conductor of the shifting electrode which does not constitute the writing cell.  
     CONSTITUTION: The voltage is applied to writing electrode W 1  and shifting electrode Y 11  to generate discharge at writing cell part A. The bus conductor crossing writing electrode conductor W is indicated by Y 2 , and thus no discharge occurs at part C when writing is carried out. As a result, the uneecessary discharge is avoided for the writing executon, thus preventing the lowering of the operation margin.

Abstract: PURPOSE:To enable to charge waste in a sanitary condition without forcing in with a bar or the like, by forming an upper part of a feed port with a bottom end submerged into the liquid in a fermentation tank into a funnel shape, and connecting the discharge part of an underwater pump and the top end part of the feed port. CONSTITUTION:The org. waste through a funnel-shaped socket 3a for waste is put through a feed port 3 into a fermentation tank 1, where the waste is agitated with an underwater pump 9 and is decomposed by accelerated reaction. The pump 9 is started upon charging of the waste, and the discharge flow through a discharge port 11 flows out from the top end of the socket 3a through a connecting pipe 5; therefore, the waste is conducted vigorously into the port 3 by said flow and its own weight. The waste arriving at the bottom end of the port  3 is displaced horizontally or diagonally downward by the discharge flow from a discharge port 10. Since a discharge valve 12 is held closed in this state, the discharge flow attains the max. of the capacity of the pump, and a high effect of feeding is obtained. Further the operator is released from the insanitary and time consuming work such as forcing with bar or the like.

Abstract: PURPOSE:To make a perpetual calendar usable in any calendar month by displaying seven groups of numerals, characters, symbols, etc., with seven different colors in a calendar day display section and day-of-the-week frames with the same colors as those used in the groups of the calendar day display section. CONSTITUTION:The color of a day-of-the-week frame 32 in a day-of-the-week displaying section 14 is made the same as that of the row of a calendar day display section, to which the same numeral as the numeral after hyphen of the frame 32 belongs. When, for example, it is required to know what day is the third Tuesday of March, 1990, the day-of-the-week column of 1990 is first checked and it is found that '3-4' is written in the third day-of-the-week frame. Since it is known that the 4th March, 1990 is the first Sunday of the March from the '3-4', the same color as that the color of the day-of-the-week frame which is sky blue is searched in the calendar day display section. Then, since it is found that numerals '4, 11, 18, 25' are colored with the sky blue, it is known that the third Sunday of the month is 18th. Therefore, it is understood that the third Tuesday of March in question is the 20th which is two days after the third Sunday, 18th March.

Abstract: PROBLEM TO BE SOLVED: To provide a rotary joint simple in structure devised certainly to take avoiding motion when a load torque is excessive and free to flexibly follow to the load side. SOLUTION: A C type spring 8 as a cushioning material is arranged between engagement protruded parts 5, 6 for torque transmission of a primary side rotary member 3 and a secondary side rotary member 4 on a rotary joint to transmit torque from the primary side to the secondary side.
