Title: Data receiver
Inventor: TSUBAKI KAZUHISA
IPC: H04B7/005
Filed: 1990-03-28
Abstract: PURPOSE:To decode a data correctly even in the transmission where impulse response changes with time by using a decoding data so as to generate a transmission signal estimating the impulse response at a succeeding time and calculating the impulse response always optimum for each decoding of the data. CONSTITUTION:When a reception signal is inputted from an input terminal 11, at first an impulse response estimate device 12 estimates an impulse response and the estimated impulse response is used and an equalizer 13 eliminates distortion in a transmission line to decode a data. Then a transmission signal estimate device 14 estimates and outputs a transmission signal string from a decoded data string every time an equalizer 13 decodes one symbol data. Then the response estimate device 12 estimates the impulse response at a newest time from the estimated transmission signal and the reception signal and uses the newest impulse response for the decoding of a succeeding data. Since the newest impulse response of the transmission line is calculated in such a way at all times, even when the impulse response of the transmission line is fluctuated with time, the data is decoded correctly in following thereto.

Patent JP-H03282042-A (JP)
Title: Torque converter structure
Inventor: KOSHIMICHI TAKAO
IPC: F16H41/24
Filed: 1990-03-28
Abstract: PURPOSE:To effectively prevent lowering of the efficiency of torque transmission by locating a spacer, having an outer peripheral surface extending along the inner peripheral surface of a core ring, in an annular space formed with the inner peripheral surface of the core ring and fixing the spacer to one of a stator, a pump, and a turbine. CONSTITUTION:When a pump 3 is run for rotation by means of a crank shaft 1, oil is delivered from the pump 3 to a turbine 4. In which case, since a slight gap 34 is provided between a core ring member 12 on the pump side and a core ring member 17 on the turbine side, oil is about to enter an annular space part 28 through the gap 34. But, since a spacer 29 is arranged in the annular space part 28, oil does not substantially enter the annular space part 28 from the outside of a core ring R. Thereby, turbulence heretofore generated in the vicinity of a core ring or in the annular space is not generated, and fluid resistance of oil is reduced. This structure improves the efficiency of transmission of torque from the pump 3 to the turbine 4 and increases an engine output.

CONSTITUTION: This adapter having a hot water supply line 2 connected to a bath pipeline 1 to which hot water is supplied from a hot water supply heater, is provided with a mixing discharge unit 8 which sucks up hot water in a bath tub from an inlet port 7 and discharges the hot water into the bath tub while mixing the hot water with hot water from the hot water supply line 2 by a suction force produced when the supplied hot water, while being turned, is discharged. When the amount of hot water in the bath tub is small, there is provided a hot water supply line on/off valve 3 which closes the hot water supply line 2. This on/off valve 3 is designed in structure so that a small amount of hot water may pass from a small hole 11 of a valve disk when it is closed.  This on/off valve 3 is opened by a coil spring-shaped valve drive means 4 which is made of shape memory alloy and deformed in specified shape at a specified temperature or higher.

Title: Electronic musical instrument
Inventor: MUTO TAKAAKI
IPC: G10H1/34
Filed: 1993-04-06
Abstract: PURPOSE:To provide the electronic musical instrument which can play a fast passage with either a strong musical sound or a weak musical sound. CONSTITUTION:When one key of a keyboard 1 is operated, a keying detecting circuit 2 detects the keying force. A CPU 5 detects the keying speed in the beginning of the keying and controls touch sensitivity on the basis of the speed. At this time, the touch sensitivity is so controlled as to rise in the beginning of the generation of a musical sound and fall with the time. Then the CPU 5 corrects the keying force by using the touch sensitivity. Further, the keying force is controlled by the CPU 5 so that its fall is reduced when the force falls abruptly after the generation of the musical sound. A sound source circuit 7 generates the musical sound on the basis of the corrected keying force or the depth of the keying.

Title: Sheet member winding device
Inventor: TERASAKA HIROYUKI
IPC: B65H75/28
Filed: 1986-04-09
Abstract: PURPOSE:To prevent defects caused by a wound portion and improve quality, by keeping at least a part of a passage of a bonding assistant agent from a transportation passage to the surface of winding cores at a temperature higher than a room temperature. CONSTITUTION:The fine particles of bonding assistant agent uniformly atomized and supplied into a transportation passage 14 are distributed further uniformly in the lengthwise direction of winding cores 3 in a static pressure chamber 11. At the time, the fine particles of the bonding assistant agent are difficult to condense because the temperature of the interior of the static pressure chamber 11 is increased by a heater 13 and even if they condense, the condensed amount of the particles is very small and they are vaporized in a short time, thus no water stays or drops. Since the fine particles of the bonding assistant agent uniformly distributed in the static pressure chamber 11 is provided with a directivity to the surface direction of the winding cores 13 through ejecting ports 15, they directly collide with the surface of the respective winding cores 15 to adhere to it. When the application of the bonding assistant agent completes, an atomizing means stops and a switching arm is actuated to return a switching bar 7 to a waiting position.
