Title: Fluidized-bed combustion equipment
Inventor: IDEI YASUMASA
IPC: F27B15/02
Filed: 1989-05-16
Abstract: PURPOSE:To make the peripheral local heat transfer coefficient in the circumferential direction of heating pipes uniform for obtaining a fluidized-bed combustion equipment that heats the heating pipes efficiently, stably by forming fluidized media into a spherical or nearly spherical shape. CONSTITUTION:A furnace 10 is divided into a fluidized-bed chamber 12 above a gas distribution plate 13 and a combustion chamber 11 below the distribution plate. When fuel gas is burned in the combustion chamber 11, and the combustion gas is spouted from gas spouting holes 13b of gas nozzles 13a into the fluidized-bed chamber 12, fluidized media 14 are fluidized and forms a fluidized bed 15. The particles of the fluidized media are of spherical or nearly spherical shape, and ceramic such as alumina, silicon carbides, etc., and magnesia are suitable for the material of fluidized media. Having a spherical or nearly spherical shape, the particles do not retain on the top of catalyst pipes 16 but roll down along the surface of the catalyst pipes 16. Therefore, the peripheral local heat transfer coefficient at the top of the catalyst pipe 16 becomes high, and the peripheral local heat transfer coefficient in the circumferential direction of the catalyst pipes 16 is made uniform, causing the catalyst pipes 16 to be heated efficiently and stably.

Title: Dot matrix printer device
Inventor: KAKIZAKI SHIGEKO
IPC: B41J2/505
Filed: 1986-05-26
Abstract: PURPOSE:To print a character having a desired inclination against a paper without using a data converting memory to obtain an easily readable document wherein an image such as a circular graph and a character are mixedly present, by controlling an angle of a printing head, a paper feed speed, and a paper feed direction according to a direction of a character to be printed. CONSTITUTION:An angle of alpha degrees is obtained from the relation of to cos alpha=beta/R, where R is the number of dots in the transverse direction of a character and beta is a paper feed length, by a method wherein a paper is fed in a plus direction by a length beta/R every time a printing of one dot-alignment is completed. After the rotation angle of a printing head is obtained, a timing control part 5 calculates a paper feed length per dot-alignment L (=beta/R) and controls the rotating speeds of a paper feed motor and a carriage motor through a paper feed control part 8 and a carriage control part 5. After the completion of printing of R dot-alignment, a printing speed and a paper feed speed are so controlled that a paper feed length many agree with beta, and the paper is fed in a positive or negative direction by the length beta/R; the direction depends on a minus or plus direction of the rotation angle alpha. Since in an inclined character, beta=0, only the rotation angle alpha of the printing head 15 is controlled.

Title: Ultrasonic measuring apparatus
Inventor: MIYATA TORU
IPC: G01N29/38
Filed: 1993-04-23
Abstract: PURPOSE:To collect a defect wave irrespective of the change of the surface state by holding a peak value of an echo detecting signal corresponding to the measuring cycle, attenuating the peak value thereby generating a threshold value, and detecting a detecting signal of the next measuring cycle with using the threshold value. CONSTITUTION:An input signal upon receipt of an echo is extracted only for a certain period by a gate circuit 16 in accordance with a gate signal from an activated gate pulse generating circuit 14a, which is held at a peak hold circuit 17. The output of the circuit 16 is input also to a comparator 18. A threshold value VTH which is a divided voltage of an output of a sample hold circuit 19a by a level setting circuit 19b as a variable resistor is input to the other input terminal of the comparator 18. A detecting signal P output from the comparator 18 triggers a gate pulse generating circuit 14b and enters a time-width variable pulse generating circuit 20, with generating a sample hold signal H. Since a next threshold value VTH is set by a peak value of the one earlier measuring cycle held by the circuit 17, it allows the detecting signal P to follow the detecting level even when it is decreased, thus realizing the detection at the level.

IPC: H01L27/04
Filed: 1990-05-14
Abstract: PURPOSE:To regulate a delay and to perform a layout of a high speed LSI by automatically inserting a buffer gate between wiring in a network in which its wiring length is increased to shorten the length between the gates. CONSTITUTION:A graph 1 representing the relationship between a distance between latches 1 and 2 and a delay value is a characteristic graph when there is nothing between the latches. Reference numeral 2 denotes a characteristic graph when a buffer gate 5 of one stage is inserted between the latches, and its delay value is reduced by (x) as compared with the delay of the same distance l of the 1. A position where the gate 5 of one stage is inserted is limited to a range as shown by 4 by the characteristic. If it exceeds this range, the delay value is reversely increased. The distance l between the latches 1 and 2 is equivalent to (l1+l2) after the gate is inserted, but it may not always be equivalent in the sense of varying the delay value. As described above, the value can be regulated to the delay value matched to its object by inserting the gate between the latches.

With the thickness of the filter paper being made about 1mm, the grooves of, e.g., at least 5W10mm in width and about 0.1W0.5mm in depth are formed. In the case of using spray water, it is effective if a pored plate 6 provided with oblong holes 6a in the paper-making direction between the filter paper layer 8 and device 4. The use of this filter paper prolongs the life of filtration because foreign matter deposits in the concave parts 5a then shifts onto the convex parts 5b.
