IPC: G11B15/20
Filed: 1979-01-12
Abstract: PURPOSE: To obtain a tape recorder featuring a small amount of force required for operation of the cue and review by giving the sequential driving to the head subsrate via two rotors and also resetting the head substrate up to the temporary stop position via the 2nd rotor in the quick winding mode.  
     CONSTITUTION: Secondary gear 48 starts turning with push of the quick winding button in the reproduction mode, and thus head substrate 26 is returned up to the position identical to the temporary stop mode. And pinch roller 33 is detached from capstan 36. At this moment, heads 28 and 29 are still at the position to touch the tape to make the tape reproduction possible. In parallel to this action, the high- speed turning is given to take-up reel stage 19 thus to secure the quick winding and cue actions while the reproduction is being given. In such constitution, the force can be reduced for operation of both the cue and review, thus obtaining a tape recorder incorporating the highly reliable and low-cost cue and review mechanisms along with a simple structure.

Inventor: HASHIMOTO TAKAO
IPC: C23F13/00
Filed: 1981-01-13
Abstract: PURPOSE: To prevent the electrolytic corrosion of an underground-buried metallic pipe by forming bond junctures electrically conducting and connecting each of said metallic pipes to the connecting parts of said pipes and connecting earth plates to the arbitrary positions of the metallic pipes.  
     CONSTITUTION: Since underground-buried metallic pipes 1, and 1' are connected to each other by means of a bond connecting wire 4 and are in a good electrical conductive state, the galvanic current in accordance with oxygen concn. cell effect and the like flows mostly in the pipes 1 and 1'. Hence, the current flowing out into the ground from the damaged parts 6 which are liable to be produced in the pressure contact parts between the pipes 1, 1' and a joint pipe 3 is considerably decreased and the breakthrough electrolytic corrosion damages from the parts 6 are considerably decreased. Since earth plates 5 are connected in the arbitrary positions of the pipes 1, 1', the galvanic current flowing in the pipes, 1, 1' flows out into the ground through the plates 5 in spite of the case in which other damaged parts 7 are produced other than in the connected parts. Hence, the current flowing from the parts 7 to the ground decreases and the breakthrough electrolytic corrosion damages in the parts 7 are decreased.

CONSTITUTION: When the prize winning to a specific prize winning port is attained, a control part selects, for example, the big hit pattern 18c of the pattern display column of a variable display device. Following that, the vertical line 18a and the horizontal line 18b are selected. In other words, nine points out of the intersections of the vertical line 18a and the horizontal line 18b are selected, and the big hit pattern 18c is displayed on selected nine points. Then, the position of the vertical line 19a is determined at, for example, three according to the number of the dice of a vertical line selection column 19a, and the vertical line 18a is displayed and identified by changing its hue. Similarly, the horizontal line 18b is also determined by the number of dice of a horizontal line selection column 19b.  When the display position of the big hit pattern 18c coincides with the intersection of the vertical line 18a and the horizontal line 18b, the variable prize winning port is opened, which sets a specific state.

Title: Character recognizing device
Inventor: TOMONO KOZO
IPC: G06K9/62
Filed: 1989-01-10
Abstract: PURPOSE:To improve the operability for correction of characters by excluding a standard character pattern contained in a recognition dictionary corresponding to the names of characters of the same form out of the recognizing subjects and at the same time adding the information on the same form character names to the recognizing candidate characters to display them on a display means. CONSTITUTION:A control means 15 excludes the characters except the head ones of each pair of same form characters stored in a same form character store table 18 out of a recognition dictionary 14 and recognizes these excluded characters via a recognizing means 13. In the case the head characters of a certain pair of same form characters are included in the recognizing character candidates, all other characters belonging to the relevant pair are added to the recognizing candidate characters and displayed on a display means 17. Thus it is possible to easily identify the same form characters which are hard to discriminate by the font only on the means 17. Then the load of an operator is reduced for correction of characters.

Title: Liquid crystal display device and its production
Inventor: NISHIMURA ETSUKO
IPC: G02F1/1343
Filed: 1995-01-13
Abstract: PURPOSE: To eliminate disconnection and short circuiting defects and to improve a yield by improving the adhesion of a stepped part with respect to a transparent conductive film. CONSTITUTION: A nearly randomly oriented polycrystalline indium tin oxide(ITO) film 101 having the ratio of the X-ray diffraction peak intensity of the (400) face to the (222) face in the range of 25 to 75% is used as the transparent conductive film of the liquid crystal display device. Since this film has a film structure densely packed with crystal grains of a uniform size, the interior of the crystal grains and grain boundaries are uniformly etched at the time of patterning the film by a wet etching method, by which a well etched end shape 103 of a forward taper is obtd. Then, the good adhesion of the upper layer film is assured in the case the other film bestrides the difference in level of the transparent conductive film.  The penetration of an etchant in the transverse direction of the stepped part is prevented even when the transparent conductive film bestrides the difference in level of the other film and, therefore, the stepwise breakage from the etched ends of the pattern is lessened and the adhesion of the transparent conductive film itself is assured.

CONSTITUTION:If a speed change lever, being controlled to a low speed position, is switched to be placed in a reverse position, a low speed shifter 13 is transferred to a position of 13A by oscillation of a select arm 21, placing a speed changer in a reverse condition. Simultaneously, a bell crank 16, being pressed by lateral movement of the low speed shifter 13 and deflected as shown by a chain line in the drawing, pulls a wire 17. Then a control member 18 is turned from a position 18A shown by a chain line to a position 18 shown by a full line in the drawing, and a lever 9, even if it is tried to be turned to the front, hits the control member 18, here a clutch 7 is engaged but a wire 10 never reaches a position exceeding a supporting point 12 of the lever 9. Accordingly, the lever 9, if it is released from pressing by hand, returns to a position as shown by a chain line in the drawing immediately disengaging the clutch 7.

Abstract: PURPOSE:To cause boiling due to local heating easily and enable to increase the transmitted amount of heat of the heat pipe remakrably by a method wherein an auxiliary heating means is provided in the vicinity of an evaporating part, wherein the operating liquid of the heat pipe is located, to heat the part locally. CONSTITUTION:A heater 3, as the auxiliary heating means, is provided at the vicinity of the outer periphery of the evaporating part M of a vessel 1 in which the operatin liquid 2 is sealed and when an electric power is supplied from an electric source 4 to the auxiliary heating means, the evaporating part is heated locally. According to this method, local boiling is caused and bubbles B are ascended, whereby, the operating liquid is mixed to generate new bubbles B. These bubbles are ascended with speed higher than that caused by natural convection while protrusions and recesses are produced at a boundary surface A and a practical evaporating area is increased. Thus, when boiling begins, the boiling is spread to the whole of the operating liquid and is continued. Acordingly, boiling is continued if the electric source 4 is put OFF therafter and highly efficient heat transmission may be maintained. A lens 5, projecting light beams, may be preferably employed as the auxiliary heating means.
