Title: Manhole construction
Inventor: KUBO YOSHIHISA
IPC: E02D29/12
Filed: 1998-08-10
Abstract: PROBLEM TO BE SOLVED: To reduce damage of a main body, the number of installations, and extension of a pipeline to reduce construction cost, by providing an inflow pipe on a manhole main body so as to slant downward, and providing a wear plate against which sewage from the inflow pipe runs in the main body. SOLUTION: A cover body 12 is connected to the upper end of an upper cylindrical body 111, and the upper end of an invert 13 is connected to the lower end of a lower cylindrical body 113. Next an outflow pipe 16 is provided on the lower end of the invert 13. An intermediate cylindrical body 112 is provided with an inflow pipe so as to slant obliquely downward on the opposite side wall to the wall provided with steps 114. Further a wear plate 15 against which sewage from the inflow pipe 14 runs, is provided on the steps 114 positioned on the opposite side to the inflow pipe 14. This position is on the extending line of the inflow pipe 14, and it is lower than the lower part of the pipe 14 and higher than the top part of the outflow pipe 16.  Hence, sewage flowing down at high speed is decelerated by the wear plate 15, and flow speed energy is converted to impact sound, heat, and the like. Hereby, the main body can be used extending over a long term.

Title: Optical character reader
Inventor: YAMADA YOSHIMI
IPC: G06K9/50
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To provide a optical character reader which is shortened in recognition processing time. SOLUTION: A document T is read by an image read part 30 for generating a multi-valued image signal S34. The image signal S34 is stored in an image memory 41, and the image signal S41 outputted from the image memory 41 is converted by a binarizing process part 42 into a binary image signal S42. The binary image signal S42 is filtered by a filter process part 43 to obtain an image signal S43. A character segmenting processing part 44 cuts character pattern areas S44 out of the image signal S43, character by character. For a character pattern area S44, an X-feature quantity extraction part 45a calculates an X-directional feature quantity S45a and a Y-feature quantity extraction part 45c calculates a Y-directional feature quantity S45c. A character discrimination part 46 collates the featured quantities S45a and S45c against the featured quantities of standard patterns so as to discriminate a character, and its code is outputted as a recognition result S46.

Title: Probe, scanning probe microscope using the probe, and recording and reproducing apparatus using the probe
Inventor: IKEDA TSUTOMU
IPC: B81B3/00
Filed: 1994-09-21
Abstract: PURPOSE: To enhance the controllability of a probe, a scanning probe microscope and a recording and reproducing apparatus which use the probe by a method wherein a shaft for a flat-board drive part is arranged on the side of an electrode apart from its center. CONSTITUTION: Two beams 9 as shafts for a flat-board drive part 8 are situated on the rear end side having an upper electrode 7 apart from the center between the tip and the rear end of the drive part 8. As a result, when the drive part 8 is driven, the movable distance of a tip part having a tip 12 becomes long with reference to the width of a gap 4 at the rear end. However, when the weight ratio W of the tip side to the rear end side becomes 1 or higher, the moment of inertia of the tip side is made large so as to lower the resonance frequency of the drive part 8. Then, an opening part 14 is formed so as to match the outer shape of the tip side, the moment of inertia in a driving operation is brought close uniformly on the front and the rear of the shafts, and a drop in the resonance frequency is suppressed.  At this time, it is most desirable that the weight ratio W is set at 0.8<W<1. In this manner, a probe which is easy to control is obtained, and the controllability of a scanning probe microscope and a recording and reproducing apparatus can be enhanced by using the probe.

Abstract: PURPOSE:To reduce silver paste being used to the extreme degree, by making the height of the semiconductor pellet mounting surface of a tab higher than the surface of the parts other than the mounting part, thereby discharging the extra silver paste when the pellet is bonded to the tabs. CONSTITUTION:A tab lead 5 has a pellet mounting part 6, on which a semiconductor pellet is mounted and fixed by silver paste and the like, and lead parts 7, whose one ends are held by a frame part or a dam lead 3. In this case, the surface of the pellet mounting part 6 is formed so that the flat surface is higher than the height of the surface of the other parts of the pellet mounting part 6 of the tab lead 5. When the semiconductor pellet is attached to the tab lead, which has a trapezoidal shape, a bonding agent such as the silver paste, which is excessively attached to the flat part of the trapezoid part of the tab lead flows down on the slant surface of the trapezoid shape, and is not discharged on the surface of the semiconductor pellet. In this way, defective pellets are decreased to the extreme degree, and the yield rate and working efficiency of the pellet attaching process can be improved.

Filed: 1989-09-01
Abstract: PURPOSE:To protect a switching element from surge voltage generated at the OFF time of the switching element at high speed or leakage currents by connecting capacitive load or the series circuit of the capacitive load and a resistor in parallel with an excitation winding. CONSTITUTION:A snubber circuit 29 is composed of the series circuit of a capacitor 27 as capacitive load and a resistor 28, and connected in parallel with as excitation winding 22. Currents flowing through the excitation winding 22 intend to continuously flow even after service interruption by the effect of an inductance component in a moment when switching element FETs 23 and 24 are turned OFF. The momentary currents are absorbed because they are charged to the capacitor 27, and subsequent currents are returned to a DC power 21 through diodes 25, 26 for feedback. Consequently, the capacitor 27 is constant-current charged at that time, and the terminal voltage of the capacitor gradually rises linearly. Accordingly, the terminal voltage of the FETs 23 and 24 also rises linearly, and the rate of rise dv/dt is brought to a fixed value.
