Title: Low-temperature nuclear fusion device
Inventor: OGINO SHINJI
IPC: G21B1/00
Filed: 1989-12-22
Abstract: PURPOSE:To facilitate a nuclear fusion reaction by occluding the deuterium generated by the electrolysis of heavy water into a cathode to induce the nuclear fusion reaction and maintaining the surface of the cathode in an active metal state by a cathode metal exposing means. CONSTITUTION:A heavy water electrolysis bath 3 is filled in an electrolytic cell 4 made of glass and the metallic anode 1 or the cathode 2 consisting of titanium or palladium is immersed in the electrolysis bath 3. The active metal atoms are exposed on the surface of the cathode when the cathode receives tensile force. The active metal atoms improves the D-D nuclear fusion on the cathode surface or the diffusion of the deuterium into the cathode, thereby promoting the D-D nuclear fusion in the cathode. The neutrons 1/0n generated by the nuclear fusion in the electrolytic cell 4 is decelerated by a polyethylene layer 12 and is measured by a neutron detector 11 consisting of <3>He.

Inventor: NITTA KEIICHI
IPC: B01D35/02
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To automatically discharge sediment by using a filter capable of treating the sediment mechanically and quickly without any need of resorting to labor. SOLUTION: A filter is divided into a filtration chamber 22 and a strainer retreating chamber 23 by use of a division 24, and many communication holes 28 are drilled through the division 24. Also, comb tooth type strainers slidable in the filtration chamber 22 and the strainer retreating chamber 23 on the operation of a power device are inserted in the communication holes 28. As a result, rubbish clamped with the strainers at a filtrating process are automatically separated therefrom with the division 24 at the time of the retreat of the strainers. A plurality of the strainers so formed are prepared, and when one such filter is operating to filtrate sediment, another filter is made to perform a backwashing operation so as to carry rubbish accumulated in the filtration chamber 22 to a filled ground on pressurized water from a pump, respectively by selecting a valve operation.  A plurality of the filters are alternately made to repeatedly perform filtration and backwashing operations for automatically discharging sediment.

Title: Echo canceller
Inventor: IMADA MASANORI
IPC: H04B3/23
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To effectively evade the deterioration of transmission quality by selectively using a main echo canceller part for suppressing an echo component and a sub-echo canceller part so as to suppress the echo component. SOLUTION: The main echo canceller part 20 generates a correction signal S8 in an adaptive filter 20a by a digital voice signal S7 and executes formation so as to subtract the correction signal S8 from the digital voice signal S5 by a subtracting circuit 20b. On the contrary, the sub-echo canceller part 21 generates the correction signal S9 in the adaptive filter 21a by the digital voice signal S7 and subtracts the correction signal S9 from the digital voice signal S5 by the subtracting circuit 21b so as to output it. The sub-echo canceller part 21 updates the coefficient value of the adaptive filter 21 a by a stipulated cycle. At this time, the sub-echo canceller part 21 stop-controls the coefficient updating operation in accordance with a control signal SEL 1.

Title: Control device of brushless motor
Inventor: USHIYAMA KIYOHIKO
IPC: H02P6/16
Filed: 1994-12-19
Abstract: PURPOSE:To reduce pull-in time of the phase control by delaying the trigger point so that the trigger point may not coincide with the minimum point of the motor torque ripple to increase the change in the rotation speed. CONSTITUTION:A delay circuit 8h is provided between a waveform shaping circuit 8a and a phase comparator 8c. This delay circuit 8h delays the trigger point for a prescribed period of time so that the trigger point of the phase control may coincide with the maximum point of the motor torque ripple. The phase control signal is transmitted from an adder 8e to a motor drive circuit 8g with this delayed trigger point as the reference, and a drive coil of each phase is energized and controlled by the motor drive circuit 8g. Because the trigger point is delayed so that the trigger point may not coincide with the minimum point of the motor torque ripple, the change in the rotational speed is increased, and the pull-in time of the phase control is reduced thereby.

Title: Exposure method
Inventor: TAKASU YASUHIRO
IPC: G03F7/20
Filed: 1987-12-29
Abstract: PURPOSE:To reduce the influence of secondary electrons and facilitate formation of a finer pattern and facilitate suppression of difference in exposure rate caused by the difference in pattern width by a method wherein a resist film and a conductive film are successively built up on a substrate and the exposure to X rays or charge beams is carried out while a voltage is applied between the substrate and the conductive film. CONSTITUTION:A resist film 2 and a conductive film 3 are successively built up on a substrate 1 and the exposure to X rays or charged beams 10 is carried out while a voltage is applied between the substrate 1 and the conductive film 3. For instance, a PMMA resist film 2 with a thickness of 1mum is applied to the silicon wafer 1 and, after the wafer is pre-baked at 170 deg.C, a carbon film 3 with a thickness of 1000Angstrom  is deposited by vacuum evaporation. Then a stainless steel foil 6 is attached to the carbon film 3 of the upper surface of the exposed substrate and connected to the cathode of a 100V source 9 and to the ground 7. Also, a stainless steel foil 8 is attached to the wafer 1 and connected to the anode of the 100V source 9. In this state, the exposure is carried out with electron beams 10. With this constitution, a force toward the silicon wafer 1 is applied to secondary electrons by an electric field in the resist so that the lateral spread of the secondary electrons can be reduced.

Title: Magnetic bearing device
Inventor: NAKAURA SHUNSUKE
IPC: F16C32/04
Filed: 1988-12-28
Abstract: PURPOSE:To prohibit to drive magnetic bearings and motors when a battery is in a poor condition by measuring battery voltage after the battery has been discharged for a specified time when a power supply for a drive device is turned on, and thereby detecting that the battery is in a poor condition. CONSTITUTION:When the first timer 5 is turned on after about 5 seconds have elapsed since a power supply 2 has been turned on, if a battery 10 is short in capacity, energizing load 11 for about 5 seconds causes its voltage to be lowered. This permits voltage at the turn-over input terminal of a comparator 9 to be lower than reference voltage, the output of the comparator 9 is thereby made to be positive voltage as required while the first transistor 14 is turned on so that the normally open contact 5a of the first timer 5 is closed. As a result, the second relay 13 is turned on, the normally open contact 13a of the second relay 13 is thereby closed so that self-hold is maintained. After about 1 second has elapsed since the first timer 5 has been turned on, the second timer 6 is turned on, then, the normally open contact 6a is closed so that the normally closed contact 6b is opened. Since the second relay 13 is turned on, a drive prohibiting signal is sent to magnetic bearings and motors so that no starting is made at all.

Title: Signal switching device
Inventor: YAMAMOTO TOMOJI
IPC: H04N5/268
Filed: 1989-12-25
Abstract: PURPOSE:To execute switching after the output of a fade circuit is made sufficiently small and to prevent a picture from being hard to be observed by controlling the changing-over of a switch based on the operation of a detecting circuit to detect the state of the fade circuit. CONSTITUTION:A comparator 56 compares the output voltage of a fade circuit 31a with the output of a voltage dividing circuit 58 and detects a state that the output of the fade circuit 31a is smaller than the output of the voltage dividing circuit 58. The outputs of comparators 56 and 57 are used as the latch pulses of latch circuits 52 and 53. Thus, when changeover switches 54 and 55 select a (b) side, the operated result of a control panel is not transmitted to the respective switches unless the latch pulses are supplied, and therefore, since the input can be switched when the output is enough lowered by the fade circuit 31, the picture is not made hard to be observed.
