CONSTITUTION:By expanding by the specified width a flaw pulse Sa included in an inspection signal subsequent to a binarizing process of a binarizing processing circuit 11 and by adding flaw data of plural scanning, for example, S2-S4, an expanse can be given to the dispersed flaw and further, accurate determination of the width of the dispersed flaw becomes available for reduction by the specified width with a flaw data reducing circuit 15a inside a flaw width mean data obtaining means 15. Further, reduced flaw data by N-time scanning are counted with a clock and the data are divided by the counted value N and a mean width W of dispersed and assembled flaws can accurately be determined. In addition to this effect, determination of the counted value N counted by a flaw-length data obtaining means 16 is possible as a length L of the total flaws dispersed as they are and magnitudes of the dispersed and assembled flaws can be obtained rapidly and accurately.

Abstract: PURPOSE:To always secure a uniform developing gap in the longitudinal direction of a photosensitive drum by allowing a developing unit to be engaged with a collar and a projecting member a with respect to the photosensitive drum whose center shaft is fixed, thereby rollingly mounting the developing unit to the photosensitive drum. CONSTITUTION:The projecting member 4d protruding on the side of a drum unit 5 is provided on a central part in the longitudinal direction of the developing unit 4, and a spring 8 is also provided on the rear of the developing unit 4. The developing unit 4 is pressed to the drum unit 5 by the pressure from the spring 8, and engaged in such a position that the collar 3 adheres to the photosensitive drum 1 and the projecting member 4d abuts on the housing 7 of a device main body; and the developing unit 4 can be freely rolled in a direction F with the projecting member 4d as the center. Therefore, even if the shaft 1a of the photosensitive drum 1 is off-centered, a sleeve 2 follows the eccentricity by means of the rolling action while maintaining the adhering of both end collars 3 to the photosensitive drum 1, and flexibly moves. Thus, the uniform developing gap (g) can be always maintained in the longitudinal direction between the photosensitive drum 1 and the sleeve 2.

Title: Vaporizing combustion device
Inventor: TAKAYAMA SHOICHI
IPC: F23D11/44
Filed: 1988-03-28
Abstract: PURPOSE:To heat a vaporizing cylinder evenly and rapidly so as to shorten the time for ignition and suppress the generation of offensive odor and white fumes so as to improve the ignitability by setting sheathed heaters in the vaporizing cylinder at its upper and lower parts as means of heating it. CONSTITUTION:When a vaporizing cylinder 1 has been heated to a prescribed temperature by two sheathed heaters 2a, 2b, a blower 9 starts to send air for combustion into a vaporizing cylinder 1 through an air duct 7 and an inlet 8. On the other hand, a fuel pump 11 also starts to send fuel through a feed tube 12 and eject it into the vaporizing cylinder 1 from the tip of a nozzle 10. The fuel is vaporized at the sidewalls of the heated vaporizing cylinder 1 and, after mixed with air for combustion, sent to a flame stabilizing plate 3 and ejected from flame holes 4. This mixture is ignited by spark discharge between electrodes 5, forming a flame 6. With the sheathed heater 2b embedded in the lower part of the vaporizing cylinder, the bottom of the vaporizing cylinder 1 is heated to a high temperature even when the discharge pressure of the fuel pump 11 is low, so that the fuel is vaporized instantaneously and pulsating combustion does not occur. The flame stabilizing plate 3 is heated by the sheathed heater 2a, so that the time for ignition is shortened.

Title: Mold clamp apparatus of injection molding machine
Inventor: SUEYOSHI TOSHIHIKO
IPC: B29C45/17
Filed: 1985-04-09
Abstract: PURPOSE:To enhance the shape accuracy of a molded product, by providing the reinforcing member provided between support plates faced to each other, a tie rod and a clamping nut and acting compression force on the reinforcing member even in such a state that max. mold clamping force is acted on a mold. CONSTITUTION:Predetermined mold clamping force is acted on a movable mold 2 and a fixed mold 34. A molten resin is injected in a cavity 36 in this state and cooled and solidified to obtain a molded product. Larger force is acted on a tie rod 16 during a time when mold clamping force is acted as compared with such a case that no mold clamping force is acted and the tie rod 16 is extended. Because of this, the force forcibly deforming a flange 12 and a fixed plate 14 is acted on the flange 12 and the fixed plate 14 from the tie rod 16 but, because compression force is acted on a reinforcing member 18 during the action of mold clamping force, the flange 12 and the fixed plate 14 can not deform easily.

Abstract: PURPOSE:To enhance the heating function of a refrigerating cycle heat- exchanging mechanism for marine cooling devices, by dividing a radiator into two sections so that a heat-exchanger is held therebetween within a box in which external cooling water is forced to circulate. CONSTITUTION:During heating coolant discharged from a coolant compressor 3 circulates through a first heat-exchanger 24, a check valve, a receiving container 8, a super cooler 9, a dryer 10 and an expansion valve 12 and then by way of a second heat-exchanger 7, and returns into the compressor 3. During this circulation the coolant raises temperature of air blown out from a blower 25 for heating, and absorbs heat stored in sea water fed from a pump 38 so that it expands and again returns into the second heat-exchanger 7 to carry out heat-exchange with the sea water. During this period the sea water fed from the pump 28 enters into a box 5 through an inlet port 22, in which the sea water makes in contact with a first circulating section of a radiator 16 and a heat exchanger 7, successively, for heat-exchanging them, respectively. With this arrangement, it is possible to increase the amount of gaseous phase coolant, and therefore, the performance of the cooling may be enhanced.

Title: Production of grain-oriented electrical steel sheet having excellent actual machine characteristic
Inventor: NAKAMURA MOTOHARU
IPC: C21D9/46
Filed: 1984-04-14
Abstract: PURPOSE:To provide an excellent actual machine characteristic to a grain-oriented electrical steel sheet by applying microstrain to said sheet without damaging the tensile insulating film then subjecting said steel sheet to a heating treatment under specific conditions. CONSTITUTION:A grain-oriented electrical steel sheet having a tensile insulating film is treated to be applied with microstrain from above the surface without giving such a damage as to expose the base iron to the tensile insulating film by selecting adequately the operating conditions for a pressing method, laser irradiating method or heat ray method. The magnetic domains of said steel sheet are thus finely segmented and the iron loss thereof can be improved but compressive strain remains in the steel sheet and steel sheet has the tendency to deterioration in the iron loss characteristic and residual strain characteristic with an actual transformer owing to various unavoidable stresses in the stage of assembling said transformer. The steel sheet after application of microstrain is thereupon heated to the temp. at which the sheet temp. does not exceed 500 deg.C. The residual compressive stress is decreased without spoiling the improved iron loss mentioned above and the deterioration of the actual machine characteristic is decreased.

Title: Muffler of two wheeler
IPC: F01N1/00
Filed: 1992-03-30
Abstract: PURPOSE:To reduce decrease of volume of a muffler and also to omit extra parts and to reduce welding length by forming a slit from an end portion of a member of a muffler structure, and by closing the slit and welding the closed portion of the slit so as to form a concave portion on a part of the muffler. CONSTITUTION:A muffler 10 is constructed as a tubular structure as a whole and is connected to an exhaust pipe 15. This muffler 10 forms a V-shape slit 17 from an end of a member 16 of the muffler structure. After this member 16 of the muffler structure has been wound to a cylindrical shape, the slit is closed together. The portion of the slit 17 becomes a flat concave shape compared with the circular cross section of the muffler 10. A concave part 20 is formed by integrating the connected part 18 of the closed slit 17 by means of a weld line 19. Thus, the concave part 20 becomes a flat plane structure, and the volume of the muffler 10 does not decrease. In addition, because the closed portion of the slit 17 only is welded, the weld line is short and the appearance is not unsightly.
