Title: Method for generating stereophonic sound and system for realizing virtual reality
Inventor: NAKAGAWA TOMOHITO
IPC: H04S1/00
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To obtain a satisfactory acoustic characteristics with respect to fluctuations at a position of an utterer, to actively eliminate a noise and to actively eliminate a noise in following to a moving object person through a comparatively simple calculation. SOLUTION: In the method for generating a stereophonic sound, the position of an utterer is estimated (1011) by using a plurality of sound input devices (microphone array 102) and a sound output devices (loudspeaker array 104), and a sound field of a stereophonic sound is controlled optimally accordingly (1012). Furthermore, using an ultra-directivity function of the microphone array (a separation function of a sound source from a noise) and generating a signal to cancel the noise actively eliminate the undesired noise. Through this configuration, a sound field is optimally controlled, even with respect to the fluctuation in a motion of a listener and a harmful noise in existence in a reproduction field can actively be eliminated. Moreover, this method is applicable to a voice recognition device and a system realizing virtual reality.

Title: Hydraulic circuit
Inventor: ISHIZAKI NAOKI
IPC: E02F9/22
Filed: 1989-10-24
Abstract: PURPOSE:To effectively utilize pump driving horse power to dissolve the shortage of flow rate by providing a valve for making the delivery passages of the first and the second pump mutually communicate with their opposite passage when the pump pressure becomes higher by a fixed value or more than load pressure on their opposite side to make the capacity of the pump on the opposite side maximum. CONSTITUTION:The lowering of load pressure Po increases the oil quantity supplied to an actuator, and a flow rate is not therefore satisfied only by the delivery flow rate of the first pump 1. In this case, a signal issued from a differential pressure output valve 11 becomes lower, and then turns into a signal to the second pump 2 to make the second pump 2 increase its delivery rate for supplying a fixed flow rate to the side of the first pump 1. In this case, the second safety valve 21 functions to set the fourth control valve 18 at a tank communicating position for making the first pump 1 attain the state of its allowable maximum delivery rate. Namely, the second pump 2 is controlled by a decreased differential pressure signal on the side of the first pump 1 to function so as to satisfy the differential pressure on the side of the first pump 1. In this case, the differential signal on the side of the second pump 2 exceeds the set pressure of the second safety valve 21, and establishes a capacity control member 1b on the side of the first pump 1 to its maximum capacity.

Title: Continuous pickling method
Inventor: YANAGI KENICHI
IPC: C23G1/02
Filed: 1985-12-09
Abstract: PURPOSE:To shorten the time for pickling by heating a material to be pickled to a high temp. then pickling the material so that the scale on the surface of the material to be pickled is made easily peelable. CONSTITUTION:The material to be pickled is heated to the temp. above the b.p. of an acid soln. under the atm. pressure. The heated material to be pickled is pickled by immersing the material into the above-mentioned acid soln. or the like. The surface scale is finely cracked at the moment when the material to be pickled is immersed into the acid soln. The scale is peeled by the quick expansion of the gas generated when the acid soln. intruding into the cracks evaporates. The time for pickling is thus shortened.

Title: Field emission display element
Inventor: TOKI HITOSHI
IPC: H01J29/86
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To provide a field emission display element having superior reliability and satisfactory vacuum level in a vacuum container because of little gas discharge from a phosphor layer in a process for evacuating the vacuum container. SOLUTION: A field emission display element 1 has an outer enclosure 4, in which a cathode base 2 with a field emission cathode 5 formed on its inner surface faces an anode base 2 with a phosphor layer 15 on its surface with an designated interval. The phosphor layer emits light through excitation by impact of electrons emitted from the field emission cathode. The phosphor layer is convered by a carbon layer 12. The interval between the cathode base and the anode base is not more than 2 mm which causes an evacuation conductance problem. Thereby, the carbon layer absorbing residual gas containing moisture is prevented and the gas adheres to the phosphor body itself. As a result, the carbon layer absorbs gas already contained in a phosphor particle.  Evacuation in an evacuating process in the manufacture of the field emission display element is facilitated, the vacuum level is improved, and reliability as a light emitting element is improved.

After that, pressurizing air is fed through the connecting pipe 14, the center duct 21 and the ducts 20 of the core 2 to grooves 18 and 19. As a result, rubber bags 5 and 5 expand, resulting in shifting the center of the core 2 to the position of the center of gravity of the internal surface of the internal tubular matter 1 and, after that, holding as shifted and at the same time sealing the lower part of a gap part 4 with the upper rubber bag 5. Under the state as just mentioned above, the fixing plate 15 is finely regulated and the lower end of the internal tubular matter 1 is fixed with a bolt or the like.

IPC: D06F33/02
Filed: 1987-10-30
Abstract: PURPOSE: To detect a cloth load quantity with extremely high accuracy by providing a means for judging the cloth load quantity at a minimum water level. CONSTITUTION: When a water level detecting means 18 detects a water level lower than the minimum water level before the cloth load quantity is detected, a water supply means 7 is operated through a washing machine process control means 8 and water is supplied up to the minimum water level in a basket 2. Afterwards, a motor control means 9 is operated, a motor 5 for rotating a stirring blade is driven for a prescribed time and stirring blades 3 are rotated in the basket 2. Within the following OFF term of a motor 5, a cloth load quantity judging means 17 compares a detecting signal from a motor voltage detecting means 14 with a cloth load quantity judging reference value previously stored in a storage means 16 and detects the cloth load quantity.  Thus, since the cloth load quantity is judged at the minimum water level with which overlap in the detection dispersions of respective cloth load quantities is reduced, the cloth load quantity can be detected with extremely high accuracy.

Title: Method and instrument for measuring characteristic of optical trigger element and power converter incorporating the same
Inventor: OGATA SHUJI
IPC: G01R31/26
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To make the turning-off time and the amount of reverse recovery charges of an optical trigger element which are the transient characteristics of the element measurable by applying a voltage which is far lower than the rated voltage of the element. SOLUTION: A forward voltage of 3-10 V is applied upon an optical trigger element, and an optical trigger pulse is applied upon an optical gate for a short time. When the optical trigger pulse is applied upon the optical gate, a forward current flows to the optical trigger element. The time required until the forward current drops to the 10% of its peak value after the current drops to the 90% of the peak value after the optical trigger pulse is applied is found and used as current reduction time. Since the current reduction time is correlative to the turning-off time and the amount of reverse recovery charges, the turning-off time and amount of reverse recovery charges can be found when the current reduction time is found.
