Title: Tension controller of recording medium
Inventor: KIMURA TAKASHI
IPC: B65H23/182
Filed: 1982-05-12
Abstract: PURPOSE:To sense tape tension at an area where the highest accuracy is needed and to prevent the tension change and the vertical vibration, by attaching a pressure-electricity transducing element to a lower cylinder and controlling a reel motor with the output of said transducing element. CONSTITUTION:A cylinder contains upper and lower cylinders 14 and 15, and a piezoelectric element 20 functioning as a pressure-electricity transducing element is attached at a part of the cylinder 15. A magnetic tape 21 is driven through a vertical post 16 at the inlet side and a slanting post 17 and then via a slanting post 19 and a vertical post 18 of the outlet side. In this case, the element 20 is pressed and a potential difference corresponding to the tape tension is produced at the output terminal of the element 20. Then a reel motor is controlled with the output of said potential difference to keep the tape tension at a constant level. Therefore, the tension is sensed at the inlet of the cylinder where the highest accuracy is needed for the change of tension. Thus, the tension change and the vertical vibration can be prevented.

Title: Method for preventing oxidation of atmosphere
Inventor: NANBA KEISHICHI
IPC: C21D1/76
Filed: 1988-03-31
Abstract: PURPOSE:To prevent the flowing of an oxidizing atmosphere into a heating chamber and further to prevent the turbulence of the atmosphere in the heating chamber by sucking raw gas and air into the heating chamber when evacuated, and thermally decomposing the gaseous mixture to form a reducing gas in the heating chamber. CONSTITUTION:Solenoid valves 14 and 15 are opened along with the movement of a high-temp. work to introduce a mixture contg. an appropriate ratio of the raw gas such as propane and air (oxygen) into ring burners 11 and 13 when the heating chamber H is evacuated. In this case, the opening degree of the valves 14 and 15 is controlled so that a small amt. of air is left after the combustion in the burner 11. The gas is ignited in the burner 13, but incompletely burned due air deficiency at the combustion port 12. Concretely, the combustion is adjusted based on the flame lengths of the burners 11 and 13. A solenoid 7 is then energized, and a stop valve 2 is opened to introduce the external air freed of oxygen into the heating chamber H. Since the chamber H is held at high temp., the sucked raw gas and air are thermally decomposed to form a reducing gas, and the oxidation is prevented. The vacuum in a furnace is simultaneously turned off, and hence the turbulence of the atmosphere in the chamber H can be prevented.

Filed: 1988-03-31
Abstract: PURPOSE:To shorten a distance from an X-ray source to a focusing point and to attain a highly intensified X-ray, by sticking a thin film of a single crystal on a surface of rotated body of Rowland circle with a rotating axis which is a connecting line between the X-ray source on the Rowland circle and the focusing point. CONSTITUTION:After polishing a plane crystal cylindrically, an asymmetric Johannson curved crystal is produced by bending the crystal troidally along a rotated body of Rowland circle with its rotating axis of a line SF. In this case, a distance SC0 between an X-ray source and the crystal, a distance C0F between crystals FZP and their total length L=SC0+C0F, in this X-ray optical system, are expressed as SC0=2R0cos(theta+theta1), C0F=2R0cos(theta-theta1), L=SC0+C0F =2R0cos(theta+theta1)+cos(theta-theta1), respectively. For a conventional crystal, the above values are expressed by putting the theta in the above equations to be 0 deg. when comparing every distance in a crystal arrangement of this optical system to that of the conventional one, a distance L from the X-ray source to a focusing point (ZFP) is shortened, thereby an intensity of the X-ray can be enhanced.

Title: Concrete tubing made through centrifugal shaping process
Inventor: HATTORI KEIKO
IPC: F16L9/08
Filed: 1989-03-31
Abstract: PURPOSE:To make uniform the bending moment at the top and the bottom of a concrete pipe when it is buried, by giving the top a different profile from the bottom, laying the centers of gravity of the top and bottom on a straight line passing the center axis, and establishing a specific relationship between the weight at each center of gravity and its distance from the center axis. CONSTITUTION:The wall thickness T1 of a concrete pipe at its top 2 is made greater than that T3 at the bottom 3, and the width (b) of the outer bottom surface 5 is made greater than that (a) of the top surface 4. If the slopes 6 on both sides of the top 2 is constructed symmetrical to the left and right, the soil pressure applied to the top 2 is dispersed by them 6, and also the reactive force to the bottom 3 is dispersed over the wide bottom surface to ensure that the bending moment generated at the top 2 and bottom 3 is made uniform. Therein the centers of gravity passing the top 2 and bottom 3 shall lie on a straight line passing perpendicularly the center axis of the pipe 1, and such a relationship as G1=r1+G2r1 is established, where G1 and G2 are weights at the top/bottom center of gravity, respectively, and r1 and r2 are their distance from the center axis, respectively. This generates equilibrium of the dynamic balance when rotating, which enables centrifugal shaping without involving vibrations.

Filed: 1983-05-10
Abstract: PURPOSE:To stabilize the idling rotational frequency of an engine just after its starting, by opening a by-pass for a throttle valve when more than a prescribed time has not elapsed since the starting and when the temperature of cooling water is lower than a prescribed level. CONSTITUTION:In a control routine executed in every 32msec, for instance, for an air control valve for opening and closing a by-pass around a throttle valve, it is judged whether a third count CSTA has exceeded a prescribed value C (4 to 10sec, for instance, in terms of time) or the temperature of engine cooling water has exceeded a prescribed level D (65-75 deg.C, for instance). If the third count CSTA is lower than the prescribed value C or the temperature of the engine cooling water is lower than the prescribed level D, a control signal is sent out to open the air control valve. The by-pass is thus opened for a prescribed time since the starting of the engine and for the period of warm-up.

IPC: B41J2/355
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a thermal transfer printer that is capable of reducing consumption of electricity at thermal head without deteriorating printing quality. SOLUTION: Control circuits 4 and 5 produce head strobe signals HD1 and HD2 out of image data S1 for each of lines for controlling supply of electricity to heating elements divided into a plurality of blocks of a thermal head. An MIX circuit 7 outputs the head strobe signals HD1 and HD2, with a time lag provided, to the thermal head 8, being synchronized with a signal specifying switching of image gradation. The time lag is decided, based on heating temperature at the thermal head. Thereby, consumption of electricity can be reduced with supply of electricity to the heating elements dispersed and deterioration in density can be restrained because of changing-over among the blocks.
