Abstract: PURPOSE:To provide the subject head of an ink-on-demand type wherein a thin flowpath tubular body and a thin magnet-distortion tubular body are combined, and the magnet-distortion tubular body is deformed by the operation of a magnetic field to press and deform the flowpath tubular body whereby ink is injected at a low voltage driving operation. CONSTITUTION:With a thin flowpath tubular body 11 fabricated by swaging a stainless steel, for example, a two-layer thin magnetostriction tubular body 15 (as one layer the flowpath tubular body 11 may be used concurrently), at least one layer of which is a magnetostriction material (such as pure nickel or the like) is engaged and fixed. A drive signal is sent to a coil 16 to cause a current to flow through the coil 16 to form a magnetic field passing through the magnetostriction tubular body 15 and the magnetic member 19. The magnetostriction tubular body 15 is minutely deformed by the magnetic field, and the pressure chamber 13 of the flowpath tubular body 11 is deformed thereby to inject ink through the nozzle 12.

Title: Exhaust pipe device for automobile
Inventor: OKUNO ISAMU
IPC: F01N1/08
Filed: 1999-05-13
Abstract: PROBLEM TO BE SOLVED: To suppress increase in an exhaust pressure by diffusing emission gas led inside an inner cylinder and discharged from an outlet port by means of a diffusion disc, passing it through a passage part having an area larger than the cross-sectional area of the inner cylinder, and introducing the passed emission gas into an inlet port formed in the inner cylinder having an area larger than that of the passage part so as to discharge it outward. SOLUTION: Emission gas, introduced from an engine into an inner cylinder 12, is discharged from an outlet port 18 and led into a primary diffusion chamber 24 to be diffused. In this process, diffusion is smoothly carried out because a diffusion disc 10 is formed into an umbrella-shape. The emission gas led into the primary diffusion chamber 24 reaches a passage part 14 while being diffused, and the pressure of the emission gas reaching the passage part 14 is lowered, because the area of the passage part 14 is set to be larger than the cross-sectional area of the inner cylinder 12.  The emission gas passed through the passage part 14 moves to a secondary diffusion chamber 26 and is led into an inlet port 20 formed in the inner cylinder 12 so as to be discharged from its rear end, and the gas pressure is lowered and introduction into the inlet port 20 is promoted because the total area of the inlet port 20 is set larger than the area of the passage part 14, so that the increase of an exhaust pressure can be restrained.

Title: Warm air heater
Inventor: UCHIDA TETSUEI
IPC: F24H3/04
Filed: 1994-05-23
Abstract: PURPOSE:To automatically switch the operation to electric heating without the need of urgent oiling even with exhaustion of a fuel and hence improve convenience by automatically starting energization of the electric heating with extinguishment of fuel heating due to the exhaustion of a fuel. CONSTITUTION:Once the amount of combustion is reduced to a predetermined value or lower during a fuel heating, an ON signal of an oiling switch 21 is inputted by a microcomputer 38. Hereby, pulse counting means 33 starts to count the number N of driving pulses for a solenoid pump, and extinguishes combustion of a burner to interrupt the combustion heating without any oiling during the counting, and simultaneously actuates a convection fan 21 with a delay through a fan controller 35 to cool a combustion part. After delay timer means 36 counts for a predetermined time, the electric heating is started with an output from the delay timer means 36. Accordingly, since the operation is automatically switched to the electric heating after the interruption of the combustion heating due to exhaustion of a fuel, the heating is switched on and off without urgent oiling, and this is preferable when an operator has a visitor, when the operator must immediately go out, and when the operator must sleep.

Abstract: PURPOSE:To extend lifetime and to improve reliability by decreasing the degree of oxidation, by providing a coating layer composed of an oxide which is a mixture of one or more than two kinds of ingredients on the inner and outer surfaces of a glow part at the top of a ceramic heater. CONSTITUTION:A ceramic heater 11 is constituted in such a manner that conductive sialon powder, for example, is kneaded with such as thermoplastic resin and it is injection-molded into a metal mold which has a specified cavity. The diameter of a glow part 20 is so molded that the thickness of the part 20 is thinner than those of lead parts 21 and 22. As for an oxide composing a coating layer provided on the glow part 20, one or a mixture of more than two kinds of ingredients chosen from among zirconium silicate, chromium oxide, aluminum oxide, magnesium oxide, zirconium oxide, and aluminum silicate can be used. It is necessary for the coating layer to have the thickness more than 2mum, at least, in order to prevent TiN contained in the conductive sialon of a heater from oxidizing, while the thermal capacity of a coating layer will increase if the thickness exceeds 100mum, as a result, the function of a glow plug will be deteriorated.

Title: Detecting device for movement quantity of moving body
Inventor: KOYAMA TAKASHI
IPC: G01D5/30
Filed: 1987-05-29
Abstract: PURPOSE:To detect even a fine pattern which can not be detected conventionally by arranging the opening of a mask nearly at the intermediate position between a light projecting element and light receiving element, and designing the width (x) of the opening of the mask so that a specific expression holds. CONSTITUTION:In a figure, there are a margin (gap) between a segment R2 and a mask opening edge 4'' and a margin (gap) between a segment R1 and a mask opening edge 4', so luminous flux regarding a low reflection part is incident on the light receiving element 2 to lower the S/N slightly. For the improvement of the S/N, the inequality I holds preferably. When the distance lbetween the mask 4 and a pattern 3 is extremely small, on the other hand, a 1st term in the right member of the expression I is a small value, so as value (x) approximates (a) and when the opening width (x) of the mask 4 becomes smaller than (a), the pattern can not be detected, so that (a) should be larger then (x). For the purpose, the mask 4 is so designed that a <=I and then the fine pattern can be detected.

Title: Recognizing device of hand-written character
Inventor: ISHIGAKI ICHIJI
IPC: G06K9/62
Filed: 1984-06-28
Abstract: PURPOSE:To divide the strokes of a hand-written character into segments and to absorb the variation, etc., of the order of making strokes in writing the character, by extracting the segments of the character depending only on the shape of the character and not on the number of strokes produced from the upward and downward movement of a pen. CONSTITUTION:Bending points are extracted from each stroke constituting an inputted character pattern and each stroke is divided into segments. Moreover, the inter-segment distance is calculated on all segment pairs between the inputted character pattern and a reference character pattern on the divided segments. Then the segment pairs of a number equal to the minimum segment number is determined under a condition where no duplication exists and the sum of inter-segment distances becomes the minimum. Thereafter, the total distance of uncorrelated segments is calculated and the value obtained by adding the total distance multiplied by a coefficient and the sum of the already correlated inter- segment distances to each other is used as an inter-pattern distance. The number of segments thus obtained depends only on the shape of the character and not on the number of strokes produced from the upward and downward movement of a pen.

The modulation degree of the reproduction signal does not satisfies the standards for CDs and such case is undesirable if the deformation rate  d is below 2nm at this time.
