Title: Single phase three wire blocking filter for power line carrier communication
Inventor: GANJI NOBUO
IPC: H03H7/09
Filed: 1990-04-13
Abstract: PURPOSE:To make the size small and to reduce number of components by constituting the blocking filter with series resonance circuits one of which is connected between a neutral line and a 1st power line connecting to a 1st coil wound unidirectionally on a core and the other of which is connected between the neutral line and a 2nd power line connecting to a 2nd coil, respectively. CONSTITUTION:A 1st coil 28 and a 2nd coil 29 wound respectively unidirectionally on a core 27 are coupled magnetically. The coils 28, 29 are connected respectively to a 1st power line 22 and a 2nd power line 23. A coil 31 and a capacitor 32 are connected between the 1st power line 22 and a neutral line 21 and a coil 33 and a capacitor 34 are connected between the 2nd power line 23 and the neutral line 21 to constitute a series resonance circuit respective ly. Since only a magnetic flux caused by an unbalanced component of currents flowing through the 1st coil 28 and the 2nd coil 29 is generated in the core 27, the size of one core in a conventional configuration is enough for the pur pose. Moreover, since the 1st coil 28 and the 2nd coil 29 are coupled magnetical ly, a capacitor 30 is in parallel resonance even with the 2nd coil 29. Thus, one capacitor 30 is enough for the purpose.

Title: Automatic steering gear for ship
Inventor: SATOU TOSHIFUMI
IPC: B63H25/04
Filed: 1979-08-02
Abstract: PURPOSE: To minimize hull propelling energy to provide the most effective steering to waves by providing a high frequency screening filter for generating output of low frequency fluctuating component and a controller having gain property.  
     CONSTITUTION: Azimuthal error ψs of difference between set azimuth ψs and actual azimuth ψr has a wave form made by the composition of high frequency fluctuating component and low frequency fluctuating one. When this error is put in the input of a high frequency cut-off filter 6, the high frequency fluctuating component is removed and only the low frequency fluctuating component ψe' is generated. Also, the controller 1 has increaseing gain property selected such that the increase ratio of command steering angle δs along Y-axis is relatively large as long as azimuthal deviation signal ψe of X-axis is small and relatively small as long as same is large. As a result, a large gain is obtained in the range of small azimuthal deviation ψe.

Title: Generator for organic gas
Inventor: TAKEUCHI SADAO
IPC: G01N1/00
Filed: 1982-06-09
Abstract: PURPOSE:To enable the continuous supply of an org. gas having a specified concn. in a large amt. at a specified flow rate for a long period of time in a generator for org. gas to be used for testing adsorption, performance of catalysts, etc., by blowing air to liquid contg. a volatile org. liquid compd. by providing a control unit for the flow rate of the gas. CONSTITUTION:The concn. of the org. material in a supply gas 10 is drawn out as the output of a measuring device 6 for concn. and the signal thereof is fed to a flow rate control unit 7 (or comparator) to detect the difference from a reference concn. Since the flow rate of the gas to be blown is regulated according to said difference, the gas can be controlled in immediate response with the excess or shortage in the amt. of the org. material. On the other hand, the flow rate of the gas 10 is set at a specified value; therefore, the concn. of the gas is held constant. In other words, a flow passage for a diluting gas is provided by bypassing a gas generator 3, and when the output from the measuring device for concn. decreases, the flow rate in the bypass flow passage is throttled to send the decreased component to the blowing side, whereby the rate of the supply gas is maintained always constant.

Title: Radio relay booster
Inventor: NAITO MASASHI
IPC: H04B7/15
Filed: 1996-04-19
Abstract: PROBLEM TO BE SOLVED: To obtain the radio relay booster that cancels a sneak path interference signal with high accuracy by repeating the update operation of a canceller control variable in a decreasing direction of a residual interference signal obtained through a very small fluctuation of the canceller control variable consisting of attenuation characteristic information and phase rotation information. SOLUTION: A controller 12 at first detects a level of a residual interference signal from a complex correlation device 14 as correlation information and decides attenuation characteristic information to an attenuator and phase rotation information to a phase shifter 9 based on the correlation information and provides an output of values obtained by fluctuating minutely the decided attenuation characteristic information and phase rotation information in both increasing and decreasing directions to the phase shifter 9 and the attenuator 10 as canceller control variables. Furthermore, the controller 12 updates sequentially the canceller control variable in a direction of decreasing the residual interference signal level from the complex correlation device 14 based on the canceller control variable fluctuated minutely.  Thus, the attenuation characteristic information and the phase rotation information are optimized and the sneak path interference signal is cancelled with high accuracy.

Title: Tacky adhesive type cleaning sheet, image forming material having cleaning member and cleaning method of image forming device
Inventor: TANAKA NAOMITSU
IPC: B08B7/00
Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To efficiently clean an object to be cleaned while the cleaning sheet maintains contact with this object and to make the sheet non-tacky adhesive at the time of inserting the sheet into an apparatus for dealing with cards in a state where pressurization is released by providing the surface of a base with a tacky adhesive layer and porous screen. SOLUTION: This tacky adhesive type cleaning sheet is provided with the tacky adhesive layer 2 on one surface of the sheet-like base 1 and is further provided with the porous screen 3 on its surface. Even if the porous screen 3 comes into contact with the object 4 to be cleaned, the screen projects from the surface of the tacky adhesive layer 2 unless there is a contact pressure and, therefore, the exposed surface 20 of the tacky adhesive layer does not come into contact with the object 4 to be cleaned and is made non-tacky adhesive. When the pressurized state is attained by the contact, the screen 3 is deformed and the tacky adhesive layer 2 is exposed from the porous part. The exposed surface 20 of the tacky adhesive layer comes into contact with the object and exhibits tacky adhesiveness. When the pressurization is released, the surface is made non-tacky adhesive and the smooth insertion of the sheet into the apparatus dealing with magnetic cards is made possible. The efficient cleaning is made executable by tacky adhesive power in the pressurized state.
