IPC: B01D29/62
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of pressure loss in a filter layer and the clogging of a supporting material by using a soft magnetic material as the supporting material for supporting magnetic powder of a filter media, magnetizing the supporting material by a magnetization device at the time of filtration and holding the magnetic powder of the filter media with the magnetic force. SOLUTION: A filter casing 8 is provided with the filter media composed of the magnetic powder on the supporting material 11 provided between a water feed port 9 and a water discharge port 10 and the soft magnetic material is used as the supporting material 11. Sewage to be filtered enters into the filter casing 8 from the water feed port 9 and is filtered through the filter layer of the soft ferrite powder of the filter media 12 before discharged from the water discharge port 10.  At this time, because the filter media 12 is leaked from the supporting material 11 to be discharged from the water discharge port 10 with the filtrate, the soft ferrite particles are stuck to each other to prevent the leakage from the filter casing 8 by applying soft weak current to a coil 14 of an electromagnet to generate weak magnetic field and magnetizing the supporting material 11 by the magnetic field.

Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To cool a retaining ring and reduce a clearance between a rotor side and a stationary side at the time of rated revolution concerning a cooling method for a gas turbine seal ring retaining ring. SOLUTION: Though air for cooling is supplied to the inside of a cavity 33 of a stationary blade 2C through an air pipe 32, air for cooling is cooled by a cooler and cools a seal ring retaining ring 22. Thermal elongation ΔB on a stationary side gradually increases after the time of starting and it is saturated at the time of rated revolution, and thermal elongation ΔA1 , ΔA2 on a rotor side also increases, but it is saturated at a smaller value than that of ΔB.  A temperature difference between the time of starting and the time of driving the seal ring retaining ring 22 becomes smaller when it is cooled by the cooler than in the case when the seal ring retaining ring 22 is not cooled, its thermal elongation also becomes smaller than conventionally, and it is possible to reduce a clearance, i.e., a difference between ΔB and ΔA1 , ΔA2 at the time of rated driving, that is, between the rotor side and the stationary side.

Patent JP-H0738412-A (JP)
Title: Level conversion circuit
Inventor: MOTOYOSHI TOSHIAKI
IPC: H03K19/018
Filed: 1993-07-16
Abstract: PURPOSE:To reduce the trailing transition time of an output signal by generating a differentiation waveform signal of an output of a current switch section and applying the signal to a base of an output transistor(TR) so as to quicken turning-on of the output TR. CONSTITUTION:One output VCT2 of a current switch section 3 is a signal changing in phase to a complementary input signal INX. A differentiation waveform signal SP of the signal VCTw shows a pulsive waveform in which the amplitude is increased positively by at least a leading edge of the signal VCT2. Thus, an output TR T13 whose base receives the differentiation waveform signal SP is quickly turned on in a timing of a leading edge of the signal VCT2? that is, an input INX. Then a trailing transition time of an output signal OUT is reduced without being affected on the turning-on speed of a phase splitter TR T9 and a faster processing speed is attained.

Title: Remote controller
Inventor: YOSHIMURA KEIJI
IPC: H04B10/2507
Filed: 1984-08-24
Abstract: PURPOSE:To perform remote operation which is not affected by a noise by transmitting the in-phase and opposite-pahse signals of a signal to be transmitted simultaneously and receiving those signals when an optical type remote controller performs transmission and reception. CONSTITUTION:A signal 6 and an inverted signal 7 to be transmitted are outputted from a transmitter 8 by light emitting diodes 9 and 10. Those signals are received by photodetection diodes 21 and 22 of a receiver 11 and further amplified by amplifiers 12 and 13. The output of the amplifier 13 is further inverted by an inverter 7. Consequently, a receiver 11 outputs the output A of the amplifier 12 as a signal 6 and the output B of the amplifier 13 as a signal 7, which is inverted by the inverter 7 to obtain a signal C. Then, only the signals A and B are received after being transmitted in air. Therefore, either one is invariably on and even if there is an influence exerted in an off period, the other is on, so no influence of the on-side signl is exerted.

Title: Phase synchronizing oscillator
Inventor: IKEMATSU HIROSHI
IPC: H03L7/093
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To reduce the component constitution of a loop filter and to solve the problem of high cost by providing a transfer function which is proportional to a specific value of a complex angular frequency and making a closed loop transfer function of a phase-locked loop, determining phase noise, contain no phase term. SOLUTION: A phase comparator 4 makes a phase comparison between the output of a voltage-controlled oscillator 1 which is divided by a frequency divider 3 and a reference signal and outputs a detection voltage corresponding to their phase difference. The loop filter 5 smooths and applies the detection voltage from the phase comparator 4 to the voltage-controlled oscillator 1 and has a transfer function proportional to 1/s3. The phase synchroning oscillator uses this loop filter 5 having a transfer function proportional to 1/s3 and causes no deterioration of phase noise due to phase delay in the transition area between an area wherein noise due to the multiplication of the PLL is dominant and an area wherein noise due to the voltage-controlled oscillator is dominant.  Therefore, the component constitution of the loop filter 5 is reducible because of approximate conditions wherein it is considered the phase-locked loop has no phase delay approximately.

Title: Optical heterodyne detecting circuit
Inventor: IWASHITA KATSU
IPC: H04B10/556
Filed: 1988-07-15
Abstract: PURPOSE:To obtain high sensitivity equivalent to a case where a dual filter is used without needing wide intermediate frequency band width by receiving an FSK signal by using an image rejection mixer. CONSTITUTION:The frequency of a local oscillating light source 1 is set to an intermediate frequency between a mark frequency and a space frequency. For an FSK signal light and a local oscillating light, the two lights, in which mutual phase difference is practically pi/2, are outputted by a polarization beam splitter 3 through a directional coupler 2. These two lights are inputted to two light receiving circuits 4 and 6 and 5 and 6. After that, outputs are added by adders 10 and 11 with dislocating one output from the other output practically by the pi/2. Next, the added two outputs are detected by envelope detecting circuit 12 and 13 and an output is operated by a subtractor 14. Thus, without needing the wide intermediate frequency band width, the high sensitivity, which is equivalent to the case to use the dual filter, can be obtained.
