Title: Flue structure for waste heat boiler
Inventor: NAKAMURA KATSUYOSHI
IPC: F22B1/18
Filed: 1990-03-19
Abstract: PURPOSE:To prevent the corrosion of water tubes by waste gas and to prolong the life thereof, by a method wherein a plurality of the water tubes are laid within a wall member and a plurality of studs formed of heat-transferring material are fitted within the wall member between the water tubes and a flue. CONSTITUTION:A wall member 4 for a flue structure 1 is formed of refractory material and within the wall member 4, a plurality of water tubes 6 are laid to surround a flue 3, and between the water tubes 6 and the flue 3, a plurality of studs 7 formed of heat-transferring material are laid within the wall member 4. One end of the stud 7 is fitted to the water tube 6 by welding and the other end thereof is exposed to the flue 3. Therefore, the corrosion by gas such as SO2 or chlorinous gas, which is contained in waste gas 2 in high temperature, occurs only at an exposure part 7a of the stud 7. In this way, the life of the water tube 6 is prolonged against the corrosion by the waste gas 2 in high temperature, and if only the stud 7 corroded is replaced or is padded, a structural function for absorbing heat is prolonged.

Title: Wire-rope test method, wire-rope testing apparatus and magnetizing head
Inventor: NIKORASU TOYAARUTO FUAN DERU B
IPC: G01N27/82
Filed: 1987-03-25
Abstract: A wire rope tester which can detect broken wires, area reductions, or wire contact irregularities. The tester includes two permanent magnetic stacks (32 to 38) which produce axial adjacent and opposed DC magnetic fields which magnetise the rope (46). Broken wires are indicated by flux variations when the flux density is at saturation (j1,j2); area reductions are related to flux variations (j1,j2); also at saturation flux density; and wire contact pattern changes produce detectable eddy current flux variations (k) when the flux density gradient is constant.

Title: Tape cassette
Inventor: HANAKAWA EIICHI
IPC: G11B23/087
Filed: 1985-04-02
Abstract: PURPOSE:To improve the grade of goods and reliability by forming an energizing means with elastic bodies disposing at both sides of an energizing force acting point on a turnable supporting spindle. CONSTITUTION:In the process that a cassette in a closed state is moved in the direction of an arrow A, the engagement between a U-shaped cover 4 and a recessed part 18 on the opening surface of the cassette main body 1 is released, and an abutting member 21 pushes up the U-shaped cover 4 to turn it. Since parts in vicinity of an upper acting point on the turnable supporting spindle 6 in terms of a flat spring 7 being the generating member of the energizing force is in arc-shaped, the lower acting point R of the energizing force is shifted on the front wall inner part 22 of a cassette lower half 3 in the direction of an arrow D together with the shift in the cassette forward direction of the upper action point Q of the energizing force, which is a contact point between them. Thus stress concentration occurring at a fixed end P can be discentralized, and repulsion arising between the upper acting point A and the lower action point R can reduce the permanent distortion. Accordingly the occurrence of the permanent distortion due to the stress concentration is eliminated with respect to the cyclical opening and closing actions of the U-shaped cover 4, thereby improving sales points and reliability.

Title: Method for correcting tracking for linear driven record player
Inventor: TANEOKA AKITO
IPC: G11B3/36
Filed: 1981-05-09
Abstract: PURPOSE:To correct tracking, by using a sensor board made of a good conductor and a high frequency coil which are interlocked with the tone arm and by performing an automatic adjusting through a specified method so that the sensor board may be kept at a fixed location. CONSTITUTION:It is arranged that, when a sensor board 11 is located at the center of coils 9 and 10 when a tone arm is located perpendicularly to a record, the electric potential at points 16 and 17 becomes the same and the output of a point 18 becomes 0 (zero). When the sensor board 11 approaches the coil 10, the output of the point 18 changes downward as shown by a curve 20, and a linearly driving tone arm controlling circuit is driven by the output. Moreover, the output moves the sensor board 11 so that the points 16 and 17 may become the same, and controls and drives the sensor baord 11 so that is may come to the center of the coils 9 and 10. Thus the location of the sensor board 11 is corrected. When the sensor board 11 approaches the coil 9, correction on the location of the sensor board 11 is performed in the reverse way, and the position of the tone arm 12 is automatically adjusted so that it may be perpendicular to the radius of the record always.

Abstract: PURPOSE:To easily measure the grounding resistance which is characteristic for the measured grounding equipment. CONSTITUTION:Each electric potential value V1, V2 of the measured grounding equipment 20 connected with an electric current electrode 22 is measured by an electrometer 23 connected with a voltage electrode 21, by turning-OFF a switch 25.

Title: Thermal transfer recording method and thermal transfer sheet
IPC: B41J2/325
Filed: 1992-03-27
Abstract: PURPOSE:To obtain a good gradation image due to a dye even on an image receiving material having no dyeing layer. CONSTITUTION:In a thermal transfer sheet 1, a plurality of ink layers respectively containing yellow, magenta and cyan dyes are formed on a heat-resistant sheet like substrate 2 and a heat-softenable transfer dyeing layer 4 is further laminated on the yellow ink layer 3Y to form a first composite layer 5. When the first composite layer 5 is pressed to an image receiving material under heating at the time of recording, the dye in the yellow ink layer 3Y is diffused to the transfer dyeing layer 4 corresponding to heat value not only to dye the layer but also to soften the same and, therefore, the transfer dyeing layer 4 is transferred to the image receiving material to form an yellow recording image. Thereafter, the respective ink layers containing magenta and cyan dyes are controlled in heating under pressure to perform lap-recording due to thermal transfer and continuous gradation recording of each color is performed. As a result, a full-color image due to dyeing can be obtained even on plain paper only by heating control.
