Title: Vacuum cleaner
Inventor: OMOTO SHUHEI
IPC: A47L9/04
Filed: 1992-01-31
Abstract: PURPOSE:To prevent a malfunction which occurs when a rotary member floats up from a floor by allowing an output of a means for detecting the rotating direction of the rotary member by noncontact to have a hysteresis characteristic and controlling the rotation of a motor. CONSTITUTION:In a suction port opened in the lower face, a cleaning rotary member driven by a motor 6 being freely rotatable forward and backward is provided. Photosensors 29a, 29b for detecting the rotating direction of a rotary member by noncontact are provided, and its output is inputted to a clock terminal CL and a data terminal D of a flip-flop(FF) 31 being a control means. An output terminal and an inversion output terminal of the FF 31 are inputted to a bridge circuit formed by a monostable multivibrator 35 and transistors Q1-Q4, FETs 1, 2, etc., of a driving circuit 32, and the motor 6 is rotated forward and backward. Also, the output of the photosensor 29a is allowed to have a hysteresis characteristic by a hysteresis means 36, and the monostable multivibrator 35 is controlled. In such a way, even if the rotary member floats up from the floor and rotates by vibration, etc., an erroneous detection and a malfunction of the rotary member are prevented.

Title: Digital camera
Inventor: SAKAGUCHI TOMOHIRO
IPC: H04N5/232
Filed: 1998-01-29
Abstract: PROBLEM TO BE SOLVED: To easily simplify the adjustment of resolution by having a zoom lens moved so that the resolution of image data photographed on a resolution chart is nearly equal to that of a prescribed resolution pattern, and deciding an initial position. SOLUTION: A digital camera 100 is mounted on an adjustment device, a CCD 103 reads a transparent resolution chart set to a light source, and image data of the resolution chart are stored in a DRAM 111 via a CDS circuit 104, an AGC circuit 105, and an A/D converter 106. A CPU 108 compares the resolution of the stored image data with the resolution pattern stored in advance in the DRAM 111. When the resolution is higher than that of the resolution pattern, the CPU 108 writes the position of a zoom lens 101b at that time to an EEPROM 114 as an initial position. When the resolution is lower than that of the resolution pattern, the CPU 108 moves the zoom lens 101b repeatedly by a prescribed amount each, until the resolution of the image data on the resolution chart becomes the resolution of the resolution chart or higher and then sets the position.

Title: Tapping method for molten steel
Inventor: UCHIDA TADASHI
IPC: C21C5/46
Filed: 1986-01-29
Abstract: PURPOSE:To prevent sticking of slag to the edge of a ladle by mounting a freely attachable and detachable coating member to the edge of the ladle, tapping a molten steel from a converter into the ladle and removing the coating member which is stuck with the slag discharged from the converter after tapping. CONSTITUTION:The molten steel to be tapped is housed in the converter 10 and the slag floats on the surface of the molten steel. The ladle 14 to receive the molten steel tapped therefrom is disposed below the converter 10. The ladle 14 is imposed on a receiving carriage 16. A slag discharge spout 18 is installed to the receiving carriage 16 adjacently to the ladle 14 to prevent the sagging of the slag onto the receiving carriage 16. The coating member 22 is put on the edge 20 of the ladle 14 adjacent to the slag off spout 18. The molten steel is tapped from a tap hole 13 into the ladle 14 when the converter 10 is tilted to rotate backward in an arrow N direction. The slag flows out of the tap hole 13 upon ending of the tapping and therefore, the tap hole 13 is raised by rotating the converter 10 in the arrow N direction. The flowing out slag spills partly on the coating member 22 and is received into the spout 18.

Abstract: PURPOSE:To compensate the decrease in the voltage of a power source due to the variation in a load by connecting a motor in series with a transistor, and detecting the input and output side voltage of an armature and the output side voltage of the transistor, thereby controlling a base current. CONSTITUTION:A DC motor M and a transistor Tr are connected in series with each other, and the motor M is controlled at a constant speed by controlling the base current of the transistor Tr.
