Title: Quantitative determination for cationic and anionic water-soluble high molecular flocculant
Inventor: IBUKI MANABU
IPC: B01D21/01
Filed: 1981-03-31
Abstract: PURPOSE:To enable precise micro-quantitative determination of a cationic and anionic water-soluble high molecular flocculant by adding ethylenediaminetetraacetate, tannic acid and inorganic salt to a disodium liquid to be treated prepared by removing suspending substances from waste water, and by applying later turbidimetric analysis thereto. CONSTITUTION:0.1ml of 0.1 N disodium ethylenediaminetetraacetate (EDTA) solution and 20ml 2 N salt water solution are added to 1ml liquid to be treated prepared by removing minute suspended substances from waste water or the like by using a membrane filter and a centrifugal separator and are agitated. Then, after 5ml 0.1 N tannic acid solution is added, distilled water is further added thereto to increase the whole quantity to 50ml. Next, hermetical sealing is made and the liquid is agitated and left as it is for 60min, and thereafter the transmittance thereof is measured by using a light having a wavelength of 554nm. On the other hand, a calibration curve is found beforehand by the same operating method by using water containing a known quantity of the aforesaid flocculant. Highly precise determination of the flocculant in the waste water is made possible by the comparison with the curve. EDTA prevents the transmittance from being affected by a colored precipitate made from metal ions in the waste  water with tannic acid.

IPC: E21D9/06
Filed: 1991-03-14
Abstract: PURPOSE:To improve the crushing performance of the crushing head of a non- open-cut replacement device for an existing pipe used in propulsive construction method. CONSTITUTION:A crushing head 23 for existing pipe crushing is connected to the top end of a cylindrical body part 22.

Inventor: IWATA HITOSHI
IPC: H01L29/73
Filed: 1994-03-18
Abstract: PURPOSE:To enable protection from breakdown by thermal runaway without using a temperature detection element or a control circuit. CONSTITUTION:A thermistor thin film 10 having negative temperature characteristics is formed, so as to electrically connect the part between a base electrode 8 and an emitter electrode 10 which are formed on the upper surface of a transistor chip 1.

Title: Magnetization of permanent magnet
Inventor: SEZAKI KOJI
IPC: H01F13/00
Filed: 1987-03-03
Abstract: PURPOSE:To enable saturated magnetization in a lower magnetizing magnetic field without reducing the efficiency of magnetizing work by applying a specific high frequency magnetic field to a permanent magnet made of an intermetallic compound whose main components are a rare earth metal and a transition metal. CONSTITUTION:A permanent magnet made of an intermetallic compound whose main components are a rare earth metal and a transition metal is magnetized by applying a pulse magnetic field after applying a 10 KHz-50 MHz high frequency magnetic field. The high frequency loss generated when the high frequency magnetic field is applied to a rare earth magnet is transformed to heat and the rare earth magnet generates heat by itself. The coercive force of the rare earth magnet reduces with the rise of temperature. Accordingly, saturated magnetization becomes possible in a lower magnetizing magnetic field. When the frequency of the high frequency magnetic field becomes under 10 KHz, the high frequency loss becomes smaller, the rise of the temperature of the rare earth magnet becomes slow and the efficiency of magnetizing work is reduced. Meanwhile, if the frequency becomes over 50 MHz, to obtain a great intensity high frequency magnetic field becomes difficult and industrial merits are lost due to a greater and higher cost power source.

Title: Circuit reset lockout
Inventor: WATSUTOZERU UBUE
IPC: F15B20/00
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To prevent the immediate restarting of a control device, by energizing reset lockout in a moment when a failure is detected, to apply a control signal. SOLUTION: When monitors P1 and P2 Are opened, and control signals S'1 and S'2 are zero, energizing a switch 31 makes an electric current pass through a switch 31 from an electric current source Q, to be led to lines 59 and 68. This opens relays R3 and R4, and instead, the electric current from the source Q can pass through a branch line 80 to be flowed, thereby cutting off a switch 91. Energy storages C1 and C2 are in a charged condition, and when relays R5 an and R6 are opened, the storages C1 and C2 can retain the relays R3 and R4 at an opened position, from the monitors P1 and P2 are closed until relays R1 and R2 are opened. This can ensure electricity feeding, passing through the lines 68 and 58, via a line 41, thereby feeding electricity of the branch line 80 by an operator.
