Title: Circuit breaker for power distribution
Inventor: INOUE HIROMICHI
IPC: H02H3/04
Filed: 1995-02-17
Abstract: PURPOSE: To control the complete power failure by a compact, simple installation by actuating a branch circuit breaker when a current flowing through a cable way has an external predetermined level lower than the predetermined level. CONSTITUTION: Control means 5 judges whether a current value of the currents detected' by current detecting means 1 is greater than the rated interrupting current; if it exceeds the rated interrupting current, an external detecting section 13 determines a delay time for that current value based on the external predetermined level; and if the current value continues beyond the delay time, then an external overcurrent signal is output. An external trip signal output section 16 inputs said external overcurrent signal and outputs an external trip signal so as to actuate a branch breaker B having an earlier priority order in accordance with the priority order set by priority order setting means 4. External switching drive means 23 sends an external trip signal to a corresponding branch breaker B based on said external trip signal for interruption.  By doing this, a complete power failure can be restricted by said compact, simple installation.

Title: Shaped beam antenna
Inventor: SHIYOUGEN KAZUYOSHI
IPC: H01Q19/18
Filed: 1990-02-13
Abstract: PURPOSE:To obtain a shaped beam antenna covering a required service area with a higher gain in response to the shape of the said service area by correcting the mirror surface so that the amplitude distribution and the phase distribution on a main reflecting mirror are equal to the amplitude distribution and the phase distribution minimizing the square sum of the difference between an object gain in the far field and an antenna gain. CONSTITUTION:A shaped beam antenna 10 consists of a feeding horn 3, a sub reflecting mirror 4 and a main reflecting mirror 5. In order to obtain a phase distribution on an aperture of the main reflecting mirror 5, the uniform amplitude distribution is assumed, then the phase distribution is optimized so that a square sum of a difference between an object gain at a gain constraint point 1 at a remote field and an antenna gain is minimized. In this case, in order to avoid a sudden change in the phase, in the process of optimizing the phase distribution, a limit is provided, which avoids the difference between adjacent phases at aperture grating points from being a required value or over. Thus, the radiation pattern by which the required range is covered with a higher gain is realized and a shaped beam of a complicated shape is obtained.

Title: Manufacture of rugged substrate
Inventor: IENAGA TERUHIKO
IPC: H01L31/04
Filed: 1998-02-12
Abstract: PROBLEM TO BE SOLVED: To obtain a rugged substrate having a desired rugged structure with excellent reproducibility, by preparing a second process in which a crystal system semiconductor substrate is subjected to surface treatment by using alkaline solution and a rugged substrate having a rugged structure on the surface is manufactured. SOLUTION: It is necessary to form precisely the optimum rugged structure for a solar battery, i.e., uneven structure in which the length between crests is preferably in the ranged of 10-50 μm and the apex angle of the crest is at most 90 deg.. When the anisotropic etching rate is too high, it is difficult to obtain the optimum rugged structure with excellent reproducibility, so that the concentration of etching solution to be used is made comparatively low. As the etching solution to be used in a second process, alkaline solution such as NaOH and KOH is used because anisotropic etching of a crystal system semiconductor substrate is necessary. When these chemicals are used, attention must be paid to maintenance management of the chemicals and chemical resistance of apparatuses to be used in etching.

Title: Amorphous toothbrush
Inventor: YAMATO HIROSHI
IPC: A46B3/22
Filed: 1995-01-09
Abstract: PURPOSE: To provide a toothbrush which can be used for a long time by attaching brush bristle to a brush part of a toothbrush so as to maintain its shape due to such a tendency that it can return to its original shape from a bent shape. CONSTITUTION: A brush bristle part of a toothbrush is set in an amorphous condition. Since the material of the brush bristle part is amorphous, such a tendency that it can return to its originals shape from a bent shape can hold the shape of the brush bristle part, and accordingly, the toothbrush can be used for a long time. With this arrangement, it is possible to eliminate a disadvantage inherent to conventional toothbrush, such that the vertical posture of the brush bristle is disturbed so as to remarkably lower the teeth brushing effects.

Title: Treatment of waste water
Inventor: SHISHIDA KENICHI
IPC: B01J23/89
Filed: 1992-02-18
Abstract: PURPOSE:To make it possible to treat a waste water containing a chemical compound which contains sulphur efficiently, if the water contains a large amount of water-soluble inorganic salts by oxidizing, in a liquid phase, the waste water which contains sulphur, using a gas containing oxygen of higher than specific concentration in the presence of a solid catalyst under pressure and at a temperature which enables the waste water to be maintained in the liquid phase. CONSTITUTION:First, a waste water fed from a line 8 is pressurized using a pump 3. Then, gas containing about 93% (>=25%) of oxygen concentration fed from a PSA device 9 is pressurized using a compressor 5, and this gas is mixed with the waste water at a rate of O2/TOD(oxygen volume in air/theoretical oxygen demand) = about 1.2. After that, this gas/liquid mixture is heated by using a heat exchanger 2 after passing through a line 10 and then is conducted into a wet-type oxidation tower 1. This wet-type oxidation tower 1 filled with a catalyst oxidizes the waste water. The waste water passes through a line 11, then is cooled by the heat exchanger 2, and runs into a gas/liquid separator 4. In the gas/liquid separator 4, a liquid level control valve 6 and a pressure control valve 7 are activated to maintain a liquid level and a pressure at a constant level.

Title: Fluid sensing pipette
Inventor: DEEBITSUDO ERU BOOGAA
IPC: G01F23/24
Filed: 1995-02-20
Abstract: PURPOSE: To minimize a required cleaning time for the inside and outside of the tip of a pipette and the quantity of cleaning liquid by producing a liquid sensing pipette, including an outside and an inside conductive pipe to prevent mutual contamination between different biological specimens. CONSTITUTION: The outside on the tip side of a pipette is completely cleaned by the action of a cleaning liquid, which is pushed back upward between the inside of a well 66 and the outside of the pipette 66 along the outside of the pipette 10, and specimens are therefore removed. The pipette 10 detects (contributes to the prevention of contamination) the invasion of the tip on the end side of the pipette into a specimen in a test tube. This fluid-sensing mechanism is accomplished through the cooperation of outside and inside conductive tubes 18, 20 with a level detecting circuit 22. In addition, a polymer tube 48 is hydrophobic, and the fluid is filliped from its inside. Thus, a part of biological fluid does not adhere to the inside of tube, and cause mutual contamination will not take place. A polymer painted film 19 also forms a hydrophobic face and obtains the same effect.  In addition, since required cleaning time is minimized, the outside diameter of the pipette 10 is minimum, and its surface area is minimized, and moreover, the polymer pained film 19 is uniformly thin, and the outside diameter is made smaller.
