Title: Electrolytic water-producing apparatus
Inventor: SHUDO AKIHIKO
IPC: C02F1/46
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To prevent excessive water pressure from applying to a pipeline connected with an electrolytic bath and to the electrolytic bath even in the case pipe choking occurs in a conduit pipe to lead out ionic water produced in the electrolytic bath. SOLUTION: This electrolyzed water producing apparatus comprises a water supply valve V1 which is opened at the time of supplying treated water to a water supply pipe 11 connected with flowing inlets 21a, 21b of an electrolytic bath 20, a flow sensor S which detects the flow rate of treated water and sends out flow rate detection signals to the water supply pipe 11 in the downstream side of the water supply valve V1, a water discharge valve V2 which is connected with a water discharging pipe 13 in the downstream side of the flow sensor S and closed at the time of supplying treated water, and conduit pipes 33, 34 which are connected with respective flowing outlets to lead out each ionic water.  In the case the flow sensor S does not send a flow rate detecting signal at the time when water supply to the electrolytic bath 20 is started by opening the water supply valve V1, a closing signal is sent to the water supply valve V1 and the water supply valve V1 is closed. Consequently, even if pipe choking occurs in the conduit pipes 33, 34, excessive water pressure application to the water supply pipe 11 an the electrolytic bath 20 can be prevented.

Title: Device for braking generator
Inventor: AIDA KEIJI
IPC: H02P3/00
Filed: 1977-12-21
Abstract: PURPOSE: To shorten the stopping time of a generator by inverting to abruptly demagnetize a rectifying circuit at demagnetizing step until field current becomes  zero completely.  
     CONSTITUTION: The input of a prime mover 2 is disconnected, a synchronous breaker 12 is opened, and a switch 7' is then switched to terminal B to invert a rectifying circuit 5 for abrupt demagnetization. When a field current is reduced to predetermined value, an AC breaker 13 is opened, and the switch 7' is switched to a terminal C to simultaneously fire all the thyristors of the circuit 5. Then, an AC breaker 14 is closed, and the switch 7' is switched to terminal D to invert the circuit 5 for abrupt demagnetization. When the field current becomes zero, a generator braking switch 16 is closed, and the switch 7' is switched to terminal E to thus supply braking field current to the circuit 5.

Title: Method for continuously observing specific area in earth observation
Inventor: HISADA YASUMASA
IPC: G01S13/90
Filed: 1986-07-01
Abstract: PURPOSE:To always observe a specific area, by mounting SAR (synthetic aperture radar) to the artificial satellite on a synchronous orbit and allowing SAR to reciprocally move in relative relation to the ground of the specific area in the air. CONSTITUTION:SAR is allowed to reciprocally move in relative relation to the ground of a specific area in the air and, during this reciprocal movement, a pulse radio wave is emitted from the antenna of SAR at a constant interval and the echo radio wave from the ground is received by said antenna. By this method, an unequal interval synthetic aperture array becoming coarse at the center thereof but becoming dense at both left and right ends thereof is formed in the space of the specific area equivalently during data processing. The energy distribution of said equivalent unequal interval synthetic aperture array within a unit time comes to a both-end distribution type and the beam width of the main lobe on a synthetic aperture antenna pattern is narrower as compared not only with usual actual aperture type radar but also with SAR and the resolving power of said array is enhanced. The received echo signal is subjected to cross-correlation processing along with reference function separately calculated and the information such as topography of the specific area is formed as an image to be outputted.

Title: Magnetic head for magneto-optical recording and magneto-optical recorder
Inventor: ISHII KAZUNORI
IPC: G11B11/10
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To make the deformation of a coil not to be generated by providing a coil in which respective both ends of a conductive wire in which a crank shaped bent is formed at the intermediate part of the coil of a magnetic head for magneto-optical recording are respectively wound in helical forms in directions opposite each other from an inner peripheral part toward an outer peripheral part to prevent stress from being imparted on the intermediate part. SOLUTION: A crank shaped bent 25 is formed at the intermediate part of a magnet wire 22 to make the difference in level of the wire equal to the height H of the cross section of the magnet wire 22. Consequently, when a coil 21 is formed by the winding of the magnet wire 22, the first layer 21a and the second layer 21b of the coil are closely adhered to be formed with the difference in level H. Thus, when the bent 25 is preliminarily provided at the intermediate part of the magnet wire 22, stress is not imparted on the intermediate part even at the time winding the magnet wire 22 and even though the height H of the cross section of the wire 22 is larger than 20% of the inner diameter of the coil 21, the deformation of the coil 21 is never generated.

IPC: B41J2/175
Filed: 1981-09-29
Abstract: PURPOSE:To bring an air flow from an air outlet into a constant velocity, by a method wherein the air pressure in an air feed path is held in a constant value through a special control of the air pressure in an air feed path, through which the air flow is jetted from an air outlet positioned facing to an ink outlet. CONSTITUTION:An air feed path 16 is provided with a pressure sensor 25, a control signal generating circuit 26 and a pump drive circuit 27.

Title: Method of decreasing nox content in gasified coal fuel
Inventor: SATO MIKIO
IPC: C10L3/00
Filed: 1988-06-25
Abstract: PURPOSE:To continuously eliminate NH3 contained as an impurity in a dry process, by supplying oxygen to a gasified coal fuel at temp. above 700 deg.C. CONSTITUTION:The NOx content of a gasified coal fuel (NH3 concn.: several hundreds to several thousands of ppm) is decreased by mixing the fuel homogeneously with oxygen, oxygen-contg. gases (e.g., or air), or compounds with generate oxygen on evaporation (e.g., H2O2), and treating at temp. above 700 deg.C. When nitrogen oxides (e.g., NO, N2O or NO2) are injected simultaneously with oxygen, they reduce the lower limit of decomposition temp. of NH3 and therefore the treating temp. may be above 600 deg.C. The amt. of injected gas is such that the concn. ratio O2/NH3=1-3, or NO/NH3=0.5-1.
