Abstract: PURPOSE:To eliminate a disturbing wave by adjusting the phase and amplitude of an excited wave of an auxiliary antenna so that the disturbed wave component in both antennas in a main antenna receiving a desired wave and the disturbing wave and the auxiliary antenna receiving the disturbing wave only. CONSTITUTION:Signals of the main antenna 1 receiving the desired wave and the disturbing wave and of the auxiliary antenna 2 receiving only the disturbing wave are distributed respectively at directional couplers 3, 4 and synthesized by a coupler 12. The signal is frequency-converted by a mixer M1, frequency-converted further at a mixer 14, the signal received by a receiver 17 is brought into the signal of disturbing wave only, a controller 19 changes the output of a phase shifter 18, a computer 20 operates and processes the data of the change in the output level of the receiver 17 so as to calculate the relative amplitude and phase of the disturbing wave of both the antennas. Then the phase shifter 23 and the amplitude adjusting device 24 are controlled by a controller 22 so that the disturbing wave component in both the antennas in the excited amplitude and phase of a spare antenna 2 is cancelled.

IPC: F23D3/10
Filed: 1984-03-06
Abstract: PURPOSE:To make a secondary flame blue and short and suppress the development of soots and carbon monoxide, whereby improving a burning characteristic, by permitting an air to flow through the upper portion of side wall of inner cylinder for thereby facilitating the mixture of secondary flame in a finely divided fashion. CONSTITUTION:While a plurality of slot-like air ports 2b is defined through the upper side wall of inner flame cylinder 2 in a kerosene stove for home use in an angular fashion, adjacent air ports are partially defined in an overlaying fashion each other vertically along the inner flame cylinder 2. A slot-like air port 2b is defined through the upper side wall of inner flame cylinder 2. An abundant volume of air flows through the air port 2b to finely divide the secondary flame 7 at its root area. Moreover, since the air port 2b is angularly arranged and overlaid relative to the part of adjacent air port 2b vertically along the inner flame cylinder 2, the mixing is facilitated to make blue and short the secondary flame. The adequate supply of air serves to facilitate combustion, prevent the development of soots and carbon monoxide etc., and improve the burning characteristic of device. Moreover, the provision of slot-like air port 2b at the uppermost portion of inner flame cylinder 2 serves to retain a good burning characteristic.

Title: Discrimination of shape of plate
Inventor: SATO KAZUYUKI
IPC: G01B21/20
Filed: 1988-02-25
Abstract: PURPOSE:To discriminate the shape of a plate, by determining waviness components from an output of a distance to the surface of the plate to obtain a deviation between an average of the waviness components and the individual waviness component. CONSTITUTION:Distances y11, y12, y13, y14 and y15 to the surface of a strip plate 2 from non-contact type sensors 1-1-1-6 are detected as output signal. A vibration component is removed from outputs of the distances to determine waviness components. Then, the waviness components are integrated for a fixed period while divided by said fixed period to obtain an average of the waviness components. Then, a deviation is determined between the results and the individual waviness component to obtain the shape of the plate 2 from the deviation. Thus, it can be identified which kind of local elongation occurs in the plate 2.

IPC: H01H85/30
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To surely stop the flowing of an overcurrent so as to break a circuit by fusing the other fusing part even if a fuse link is made conductive by the electric discharging of the tip of a fusing part during the fusing of the fusing part of the fuse link when the overcurrent is supplied. SOLUTION: A self-extinguishing device 1 is composed of a fuse container 2 and a fuse link 3. The inside of the fuse container 2 is divided by partition walls 5a and 5b, and filled parts 7a and 7c filled with arc-extinguishing materials and a cavity part 7b are provided. The fuse link 3 includes fusing parts 10a and 10b having small fusing areas and a fusing part 10b having a large fusing area in positions corresponding to the filled parts 7a and 7c and the cavity part 7b. If an overcurrent is large, the fusing parts 10a to 10c are fused almost simultaneously. If an overcurrent is small, first the fusing part 10b is fused and, when the fusing part 10b becomes conductive by arc discharge, the fusing parts 10a and 10c are subsequently fused. Thus, overcurrents are surly cut off.

Title: Earthquake resistant glass and block wall executed by rocking interlayer displacement method
Inventor: TANAKA KAZUYOSHI
IPC: E04B2/90
Filed: 1996-01-25
Abstract: PROBLEM TO BE SOLVED: To cause a block wall to follow the displacement of a building frame so as to enhance earthquake resistance at reduced cost by enabling the building frame and both sides of the block wall to slip vertically, and enabling the boundary between the building frame and the wall to move vertically or downward so as to cause rocking of the wall. SOLUTION: The ζ of vertical displacement is distributed into upper ζ UPPER and lower ζ D to make it as small as possible, while the δ of horizontal displacement is made as large as possible. Further, a pivoting distance W1 is reduced, and displacement angle ζ U/W1 is increased to increase the height of a wall face. If the wall is rotated by a rocking angle in an inplane direction, the position of the boundary between the side face of the wall and a building frame is moved. Therefore, the boundary between the wall and the building frame needs to be capable of slipping in the in-plane, vertical direction. At the same time, each wall corner is displaced vertically by the value of Ζ.  Thus the boundary including the upper part or upper and lower parts of the wall face needs to be capable of being displaced in the in-plane, vertical direction, Thus by permitting vertical slip and displacement, the wall is rocked in an earthquake, resulting in enhanced earthquake resistance.

IPC: G03G15/00
Filed: 1999-02-23
Abstract: PROBLEM TO BE SOLVED: To attain efficient trouble shooting by easily and automatically detecting the failure of a photoreceptor in a copying machine having complicated multiple functions. SOLUTION: A photoreceptor patch uniformity test 128 is executed as one of tests for detecting the failure. In the test, a sample is obtained every 1.5 mm in the whole of the surface of the photoreceptor by a black toner area covering level sensor (BTAC). Seam detecting algorism is used, a seam sample is thrown away and a value for showing the total uniformity of a cleaning belt is calculated from the residual samples. This value is used as a reference value. Since the position of a seam is judged, the position of each process control patch and a corresponding BTAC reading value can be analyzed. An average and dispersion are obtained in each patch and compared with the reference value. The uniformity of each position is calculated by a statistical analysis and compared with the reference value.  When the uniformity is lower than its permissible level, an operator is informed of the exchange of a belt.

Title: Collector plate for molten carbonate fuel cell
Inventor: SHIMIZU YASUSHI
IPC: H01M8/02
Filed: 1994-03-16
Abstract: PURPOSE:To form a collector plate having legs disposed densely, having a large leg height, and having a small aperture part surface on a surface to be tightly applied to an electrode from a single plate by bending a thin metal plate into a wavy form for the collector plate. CONSTITUTION:A collector plate 20 is formed by applying bend work to a metal thin plate to be formed in a wavy form. where a width (a) at a peak part of each crest of the wavy form is set to be larger than a width (b) at a foot part. A surface where an electrode gets in contact is formed flat, and a number of small holes 23 are provided in it. When the electrode gets in contact with the collector plate 20, each trough part becomes an aperture part to the electrode, where the width (a) can be kept large in spite of the narrow aperture part because a>b at the peak part. Contact resistance can thus be reduced. In this form, the collector plate 20 can be set high relatively freely. Where the whole height of the collector plate 20 is set at 2.5mm-4mm, with a passage length set at 1m, pressure loss is 30mmAg/300mmAq. This pressure loss gives the optimum system efficiency of a cell.
