Title: Method and device for driving windshield wiper
Inventor: KUROYANAGI MAKOTO
IPC: B60S1/32
Filed: 1981-06-03
Abstract: PURPOSE:To reduce the noise of inversion of the blade of a windshield wiper and heighten its durability, by changing the centrifugal force of a weight interlocked with the blade, into a force for pushing the blade on the windshield and by making the pushing force zero at the time of the inversion of the blade on its upper and lower stroke limits. CONSTITUTION:A swing arm 14 fitted with a weight 13 on the tip of the arm is coupled to the shaft 9 of a windshield wiper so that the swing arm is pinch-held between a pivot lever 10 and a holder 11 which supports the shaft 9. The arm 14 swings in connection with the rocking motion of the lever 10. At that time, contrifugal force acts to the arm 14 because of the weight 13 to push and open the holder 11 and the lever 10 from each other. The push-opening force is transmitted to the shaft 9 and the arm 1 to push the blade 3 of the wiper on the windshield. When the direction of movement of the wiper blade 3 is inverted, the force which pushes the blade on the windshield is zero because the speed of the swing of the arm 14 is zero at the time of the inversion.

Title: Optical gyroscope
Inventor: TAI SHUICHI
IPC: G01C19/66
Filed: 1987-04-06
Abstract: PURPOSE:To obtain a simple, small-sized gyroscope by using a semiconductor laser which has a diffraction grating formed on an active layer as a light source and composing a ring laser of a single-mode optical fiber without using an optical fiber coupler. CONSTITUTION:Light emitted by the active layer 13 is propagated clockwise and counterclockwise to an optical fiber loop 9 from its upper and lower ends and further travels in the loop plural times through the active layer 13. Simultaneously, part of the active layer propagated light is diffracted by the diffraction grating 14 and exits from the semiconductor laser 10 at right angles to the active layer 13 to the left as shown in a figure. Consequently, when the whole system rotates, the clockwise and counterclockwise propagated light beams in the ring lasers 9 and 10 differ in oscillation frequency by Sagnac effect. Consequently, those light beams interfere with each other and reach a photodetector 4 as a beat signal. The frequency of this beat signal is proportional to the rotary angular speed, so the rotary angular speed given to the system is known.

Abstract: PURPOSE:To obtain an image fixing device of electrophotographic image forming device which can prevent degradation of image quality due to the toner stuck to a heat resistance film, in a simple constitution. CONSTITUTION:An image of toner 19 formed on a recording medium 18, is fixed to the recording medium 18 by laminating, heating and pressurizing a heating body 11, and a heat resistance film 14. A heat resistance film 14 is supplied from a supply side reel 15, carried at a speed the same as that of the recording medium 18 between a heating body 11 and a pressurizing roller 13 held by means of a heating body support member 12, then collected by means of collecting side reel 17 via a film carrying roller 16.

Title: Gas-filled breaker
Inventor: KOSHIZUKA TADASHI
IPC: H02B13/02
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a gas-filled breaker in which the number of components is reduced and in which an applied steep surge voltage is distributed uniformly by a method wherein an upper-end-part shield is supported by a resistor which is constituted in a hollow cylindrical shape. SOLUTION: A resistor 20 has a cylindrical shape, an upper-end resistor shield 10 is supported by the resistor 20 itself, and it is not required to install an insulating column or the like. As a result, the number of components for the breaker can be reduced. In addition, since the outside diameter in the central part in the up-and-down direction of the resistor 20 is larger than the outside diameter in a part near the upper-part resistor shield 10, the resistance value per unit length of the resistor 20 in the central part becomes higher than that in the part near the upper-part resistor shield 10. As a result, when a high-frequency surge voltage is applied to the resistor 20, it is possible to prevent that its end part becomes a high voltage.  Consequently, when a steep surge voltage is applied to a resistor shield device 9, a voltage share is reduced, and it is possible to prevent a local temperature rise.

Then, if there is no skip of the sound, dubbing from the CD to a tape is continued. On the other hand, when the absolute time elapsed becomes apart more than + or -1 second, and it is decided that there is the skip of the sound, the control part 3 detects it, and since it controls the CD player 1 and the tape recorder 2 so as to execute automatically the dubbing over again, inconvenience for a user to have to continue to hear the sound is eliminated. Thus, the failure of the recording due to the skip of the sound of the CD is almost perfectly prevented.

Abstract: PURPOSE:To detect a static magnetic field or a magnetic field in a low frequency area at a high accuracy irrelevant to temperature changes by processing output of an AC amplifier for amplifying output of a magnetoresistance effect element (MR element) synchronizing changes in a bias magnetic field.
