Title: Three-phase transformer
Inventor: OKAMURA KATSUYA
IPC: H01F27/34
Filed: 1984-10-01
Abstract: PURPOSE:To improve the reliability in the thunder resisting insulation and to provide a light-weight and small-sized transformer by grounding the two terminals of a tertiary winding with DELTA-connection through a non-linear resistance element, and connecting the 3 terminals each other through non-linear resistance elements. CONSTITUTION:The three-phase transformer has a primary winding 10 with Y- connection, a secondary winding 20, and a tertiary winding 30 with incorporated DELTA-con nection. The winding 30 has a non-linear resistance element 51 connected to the tank through its terminals (a) and (c), a non-linear resistance element 52 connected between the terminals (a) and (b), and a non-linear resistance element 53 connected to the tank through its terminals (b) and (c). In such a construction, for example, an excessive voltage will not be produced even if a thunder impulse voltage invades into the (u)- terminal of the winding 20 since a voltage will be induced at the (a)-terminal of the winding 30 or the element 51 will activate for the inter-phase between the (a)-terminal and ground, and the (a) and (c)-phases, thereby activating the inter-phase element 52 between the (a)- and (b)-phases. This results in the improved reliability of the thun der resisting insulation and a light-weighted transformer due to the reduced main gap distance between the winding and iron core, and between the windings.

Title: Microwave resonator
Inventor: MIYA TATSUYA
IPC: H03B5/18
Filed: 1993-07-27
Abstract: PURPOSE:To prevent undesired oscillation by providing a stub at a position on a microstrip line apart from a connecting point between the microstrip line and, a negative resistive element by a specific length, thereby reducing a negative resistance at an undesired frequency. CONSTITUTION:A stub 6 is provided at a position apart from a connecting point A between a microstrip line 2 and a negative resistive element 1 by a (2n-1)/4 wavelength ls with respect to an undesired oscillating frequency (n=1, 2). The stub 6 on the microstrip line 1 acts like changing a frequency characteristic of the negative resistance when viewing from a termination resistor 4 toward the negative resistor, resulting that the impedance when viewing from the negative resistive element 1 toward the termination side is high at an undesired oscillation frequency. Thus, the oscillating condition is not satisfied at the undesired frequency. That is, the stub 6 acts like decreasing the negative resistance at the undesired frequency with respect to the negative resistive element having often caused undesired oscillation.

IPC: H01F27/12
Filed: 1989-08-09
Abstract: PURPOSE:To improve heat radiating efficiency and achieve lighter weight and miniaturization by forming an oil passage with closed annular space bounded by an inner cylinder, an outer cylinder, an upper cover and a lower cover, and radially providing corrugated ribs on at least inner or outer side of the inner cylinder and connecting an upper and a lower manifolds to the oil passage. CONSTITUTION:A radiator 4 is a can member wherein an oil passage 10 is provided in a double cylinder consisting of an outer cylinder 14 having corrugated ribs 14a and an inner cylinder 17 having corrugated ribs 17a, and the central part of the can forms a cavity part 15. A part of an upper cover 9 is connected to an upper manifold 3 and a part of a lower cover 13 is connected to a lower manifold 5. That is, the radiator 4 achieves the radiating effect due to the outward radial corrugated ribs provided on the outer periphery thereof, and the air flow blowing through the cavity part 15 upwardly with increasing speed due to chimney effect. This construction also achieves radiating effect due to inwardly and radially provided corrugated ribs 17a. Thus, radiating effect, i.e., the radiated heat amount per unit area and per unit temperature, can be increased.

Title: Cleaner for condenser cooling pipe
Inventor: KUBOTA SHOZO
IPC: F28G1/12
Filed: 1998-07-21
Abstract: PROBLEM TO BE SOLVED: To prevent a duct from being choked through adhesion and growth of a marine organism by providing a function for conducting sea water constantly through the entire apparatus even when ball cleaning operation is not performed. SOLUTION: A ball separator 10 is disposed between ball circulation pumps 2A, 2B and change-over valves 3A-3C. The ball separator 10 has a grid not passing a ball and the ball and the ball flows out to a ball outlet together with sea water and only sea water flows out through a sea water outlet. At the time of cleaning operation of a condenser 7A, the change-over valve 3a conducts between the ball inlet side and the ball collector 4A side whereas change-over valves 3B, 3C conduct, respectively, between the sea water inlet side and the ball collectors 4B or 4C. Consequently, the ball circulates through a duct leading to the condenser 7A and only sea water flows into condensers 7B, 7C. Since sea water does not stand at any part, the duct is prevented from being choked through adhesion and growth of a marine organism.

Title: Measuring method for cao content in steel
Inventor: KURAHO HIROFUMI
IPC: G01N27/06
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To quickly and surely determine the CaO content in steel by using an inert gas melting method to separate oxygen derived from the CaO in steel from that derived from oxides in the steel other than CaO for measurement of the oxygen content derived from the CaO in the steel. SOLUTION: A block-shaped steel sample is put in a graphite crucible by a predetermined amount. Using an inert gas melting device, power is supplied to heat the graphite crucible in an inert atmosphere. The sample is melted by the heating, complex compounds contained in the sample are decomposed, and the oxides decomposed or those in the sample are reacted with carbon constituting the graphite crucible, thus producing CO or CO2 gas. Using either infrared absorption method, a detecting method using a heat conductivity detector, or a detecting method depending on changes in electric conductivity, the oxygen content is measured for every gas produced at each of predetermined temperatures (applied power).  Therefore, oxygen derived from CaO, depending on a predetermined extraction temperature, can be separated and specified, and the CaO content in steel can be determined quickly and surely based on the oxygen content separated and specified.

Title: Hair cutting device
Inventor: IKUTA TOSHIO
IPC: B26B19/14
Filed: 1988-08-19
Abstract: PURPOSE:To reduce the cutting resistance and shorten the time necessary for cutting hair by setting an inner cutter positioned on the inner peripheral side of an inner cutter basic board which is revolution-driven and an inner cutter positioned on the outer peripheral side so as to be shifted in the peripheral direction of the inner cutter basic board and superposing the locusci of revolu tion of the both inner cutters. CONSTITUTION:Three inner cutters 2b are installed on the outer peripheral side of an inner cutter basic board 3, and three inner cutters 2a are installed on the inner peripheral side, and urged to the outer cutting edge 1 side by a pushing-up spring 22. Since the inner cutting edge 2a on the inner peripheral side and the inner cutting edge 2b on the outer peripheral side are shifted by each nearly half pitch in the peripheral direction of the inner cutter basic board 3, the simultaneous cutting of hair on the both inner cutters 2a and 2b is hardly carried out and the cutting resistance is reduced. Further, the outside of the inner cutter 2a and the inside of the inner cutter 2b are set so that the locusci of revolution are superposed by beta each other. Therefore, a region which is not used for cutting is reduced to zero, and the chance of cutting hair can be increased.
