Title: Electronic musical instrument
Inventor: NAKADA HIROSHI
IPC: G10H1/053
Filed: 1978-02-10
Abstract: PURPOSE: To obtain portamento effect tones by providing means of adding correction values to change frequency information numerical values at specified timings and forming new change frequency information numerical values.  
     CONSTITUTION: With the change frequency information numerical value F' being inputted to the B input end of a subtractor 12 as a current value FA and the frequency information numerical value F being inputted to the A input end of the subtractor 12 as a target value FB, the difference between this target value FB and the current value FA is added as correction value to the current value FA each time when portamento clock PCL is generated, whereby the current value FA is subsequently changed. Such operation is repeatedly performed until the current value FA coincides with the target value FB, i.e., the value of the differential signal D outputted from the subtractor 12 becomes zero, whereby the change frequency information numerical values F' subsequently changing toward the target value are formed and the portamento effect tones are obtained from a sound system 7.

Title: Cathode-ray tube
Inventor: MISONO MASAYOSHI
IPC: H01J29/50
Filed: 1994-02-08
Abstract: PURPOSE:To improve a focus characteristic in the whole image screen area and the whole electron beam current area, and obtain excellent resolution by arranging an intermediate potential electrode between deflecting aberration correcting electrodes, a focusing electrode of an electron gun and a positive electrode in a deflecting magnetic field of a cathode-ray tube. CONSTITUTION:After passing through first to third electrodes 1 to 3, an electron beam 10 emitted from a negative electrode K brings a focus on a fluorescent screen 13 by an electric field of a main lens 38 formed between them and a positive electrode 4. When the beam 10 is deflected by a magnetic field of a deflection yoke 11, deflecting aberration correcting electrodes 39 are arranged in the magnetic field of the yoke 11, and a focusing or diverging condition of the beam 10 is controlled according to a deflection angle. An intermediate potential electrode 3' on which intermediate electric potential of electric potential to be impressed on the respective electrodes is impressed, is interposed between the electrodes 3 and 4 of the main lens 38. Thereby, in the beam 10, even if the deflection angle is increased, since the enlargement of a spot in an image screen peripheral part is reduced, a high resolution image can be reproduced.

Filed: 1990-01-24
Abstract: PURPOSE: To make it easy to monitor the liquid surface in a container by monitoring the attenuation of a diffused stress field which is propagated in a sound-wave propagation member. CONSTITUTION: A transducer 18 which is coupled with the propagation member 16 for an ultrasonic wave, etc., transduces electric pulses from a pulse generator 22 into a stress wave and sends it out to the member 16. The stress wave is propagated in the member 16 and echoed to produce the diffused stress field. The diffused stress field is attenuated by the member 16 itself and liquid touching the member 16 and its attenuation quantity is affected by the area of the part that the liquid touches. Therefore, the transducer 20 detects the level of the diffused stress field and an amplifier 24 and an analyzer 26 measure the attenuation of the diffused stress field and output it to a display device 28 and a recorder 30. Consequently, the liquid surface in the container can be monitored.

In succession, the weighed article weighed by an electronic weigher 1 is delivered into a fixed shoot 4 by an operation of a device 3 which turns over the precision weighing scale 2. The weighed article on the scale 2 is a failed article when it exceeds a prescribed value, and then the weigher 1 senses it and makes a movable shoot 5 leap up. Therefore the failed granular body is made to flow from the shoot 4 to a fixed shoot 15, discharged outside a cover 9 made of acrylic resin and collected in a vessel 7. A passed article is collected in a vessel 6 through the shoots 4 and 5 and conveyed by a conveyor 8.

Title: Production of urethane compound
Inventor: OKAWA TAKASHI
IPC: C07C271/20
Filed: 1991-01-17
Abstract: PURPOSE:To produce a urethane compound to be an intermediate raw material for producing isocyanates by an industrial and advantageous method. CONSTITUTION:A formamide compound is reacted with an amine compound and a carbonic acid ester in the presence of dimethyl carbonate or methyl formate in the absence of a catalyst at 100-200 deg.C temperature. Since a catalyst such as a metallic alcoholate adversely affecting the thermal decomposition step of the resultant urethane compound is not used, the high-quality urethane compound can readily be separated and recovered from the reaction product solution. Thereby, control of moisture is not required and a low-quality amine compound and dimethyl carbonate can be used as raw materials.

Filed: 1983-01-31
Abstract: PURPOSE:To prevent wrinkles from being generated during heat treatment by laminating multiple shadow masks prior to molding and flatly shifting the laminated shadow mask from the inlet to the outlet of a furnace to heat it in the furnace. CONSTITUTION:A mesh belt 201 is flatly constituted from the inlet A to the outlet B of a furnace 200, and a laminated shadow mask 51 to be heat-treated is flatly shifted through the furnace without being tilted while being mounted on the belt 201 and is heated at a heating section 101.

Title: Coordinate input device
Inventor: KOBAYASHI KATSUYUKI
IPC: G06F3/043
Filed: 1988-01-28
Abstract: PURPOSE:To improve the operability of a coordinate input device by detecting the difference of the arrival delay time between the horizontal and vertical wave components of different transmission speeds. CONSTITUTION:An information input/output device performs the input of coordinates to an input tablet consisting of a vibration transmitting plate 8 via a vibration pen 3. Based on this input of coordinates, an input picture is displayed on a display device 11 put on the input tablet. The plate 8 transmits the vibrations received from the pen 3 to three vibration sensors set at the corner parts. These transmission time of vibrations are measured for detection of coordinates. The elastic waves transmitted into the plate 8 consist of the horizontal and vertical wave components which have different transmitting speeds despite the same frequency. Thus the waveform of a detection signal contains a vertical waveform WL arriving first the sensor 6 and a slow horizontal waveform WS. Then the transmission speeds of both waves are previously measured so that the coordinate position is detected from the difference of arrival time between both waves.

Title: Ink jet recording device
Inventor: SAKAE MASAJI
IPC: B41J2/13
Filed: 1983-02-04
Abstract: PURPOSE:To obtain a simplified and stabilized ink jet recording device by a method wherein electric fields for applying the compensating deflection to ink particles are given to charging electrodes so as to compensate tilt distortion. CONSTITUTION:Information signals 36a and 36b are connected to charging electrodes 37a and 37b in a pair, respectively. When it is desired to obtain an image free from tilt distortion irrespective of the directions X and X' of the movement of an ink jet recording element 3, it suffices to generate compensating electric fields in the directions opposite to said directions of the movement respectively. In other words, when the ink jet recording element 3 moves in the direction X, compensating electric fields are generated by compensation signals Vc and Vc' so as to apply to ink particles 35 the compensating deflection in the direction x' reverse to the direction X of the movement. When the element 3 moves in the direction X', compensating electric fields are generated by compensation signals Vb and Vb' so as to apply to the ink particles the compensating deflection in the direction (x) reverse to the direction X' of the movement. By this method, the image free from the tilt distortion can be obtained even when the movement is made in both directions X and X'.
