Title: Jet stirring construction method and jet stirring device
Inventor: KOIWA YOSHINOBU
IPC: E02D3/12
Filed: 1991-03-20
Abstract: PURPOSE:To prevent dead air from being produced in the ground and discharge the slurry replaced with ground hardening agent in a jet stirring construction method. CONSTITUTION:A jet nozzle 71 is arranged facing downward at a specified angle, and ground hardening agent and air are jetted into the ground 84 so that the top of the improved ground by means of ground hardening agent and air becomes a circular cone shape. The air dispersed in the ground is collected along the inclined surface 86 of the circular none shape of the improved ground to the center of the hole excavated by a multilayered pipe rod 20, and the slurry replaced with the ground hardening agent is discharged outside due to the lift effect when the air is raised through an excavation hole 87 and discharged outside.

Title: Drive release device for image forming device
Inventor: FUKUCHI YUTAKA
IPC: G03G15/20
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To sufficiently ensure the space for the disposition of a drive release mechanism component, to reduce the size and cost of the mechanism component, and to smoothly perform a drive release operation by providing a drive release member in a fixing means. SOLUTION: In the case of causing the jamming of sheet, an idle gear 33 and a fixing gear 23 are disengaged. Therefore, a door 5 is opened and the pressing of a lever 26 by the projection 24 of it is released. Consequently, the pressing force of a torsion spring 22 turns the lever 26 in the clockwise direction of a bi-directional arrow and moves a link 21 in the left direction of a bi- directional arrow with the projection 24 of the link 21 sandwiched between the forked portion of the lever. The stopper 27 of the link 21 also moves leftwards. A bracket 29 engaging with the stopper 27 rotates in the clockwise direction of a bi-directional arrow against the pressing force of a plate spring, and separates an idle gear 33 from a fixing gear 23 to release both rollers. Thus, the jammed sheet can be pulled out only with the rotating torque of both the rollers.

Title: Magnetoresistance element, terrestrial magnetism azimuth sensor and method for magnetizing magnetoresistance element
Inventor: KAWAMURA NAOKO
IPC: G01R33/09
Filed: 1995-05-29
Abstract: PURPOSE: To enhance the measuring accuracy of a terrestrial magnetism azimuth sensor that detects an azimuth of terrestrial magnetism by using a magnetoresistance element consisting of a magnetoresistance film which is patterned so as to form a plurality of magnetic field detection sections disposed in parallel to each other. CONSTITUTION: This magnetoresistance element utilized for terrestrial magnetism orientation sensor is formed so that widths W1-W6 of respective magnetic field detection sections 1a-1f of a magnetoresistance film 1 are different from each other. An AC demagnetizing field is applied to the magnetoresistance film 1 beforehand, then the magnetic field detection sections 1a-1f are magnetized being alternately reversed to each other. Thereby, variation of a value of resistance of the magnetoresistance film 1 at the time when the magnetic field is applied in the positive direction C is equal to that at the time when applied in the negative direction D. Therefore, it is possible to eliminate measuring error caused by the difference of the variations of resistance values corresponding to respective magnetic field applying directions, thereby enhancing the measuring accuracy.

Title: Transporting cart
Inventor: YAMAZAKI TAKEJIRO
IPC: B66F9/06
Filed: 1994-05-20
Abstract: PURPOSE:To make a cart get over a stepoff with high safety and completely by mounting an auxiliary torque mechanism which gives auxiliary torque temporarily to a traveling wheel, using human power as a driving source. CONSTITUTION:By inclining an operating steering wheel 4 to lift up a cargo, air pressure can be accumulated in the accumulator 82 of an air pressure supply system 8. When an operating part 9 is operated with the cargo on a platform 1 brought into proximity to or contact with a stepoff, air pressure accumulated in the accumulator 82 of an air pressure supply system 8 is discharged to a housing 7 to apply rotating power to an impeller 6. The rotating power applied to the impeller 6 is transmitted to an axle 5 and becomes auxiliary torque F for getting over the stepoff of the traveling wheel 2. It is thus possible to make the traveling wheel get over the stepoff completely.

Title: Method for refilling oil with automatic oil filling up device
Inventor: HASHIMOTO MASAJI
IPC: B67D7/28
Filed: 1988-05-27
Abstract: PURPOSE:To reduce time from starting of oil supply to the end thereof without erroneous operation by a method wherein negative pressure is compensated by air flowing-in via an opening during normal operation, with closing of the opening detected by the rise in the negative pressure, oil supply is stopped, and oil supply is started before oil or bubbles completely flow out. CONSTITUTION:When an opening 37 to the atmosphere of an air supply path 27 is closed by oil or bubbles, a negative pressure sensor 34 detects negative pressure rising in the air supply path, and oil supply is temporarily halted by a device for halting oil supply during time required for bubbles to disappear. When halting of oil supply by the device is released and oil supply is resumed, the negative pressure does not drop until oil or bubbles remaining in the air supply path 27 are forcibly exhausted via a negative pressure generating device. Until the oil or bubbles are exhausted, that is, until the negative pressure temporarily drops, halting of oil supply by the device for halting oil supply is prevented even if the negative pressure sensor 34 detects oil or bubbles.

Title: Method and apparatus for exposure with contact mask
Inventor: USUDA KINYA
IPC: G03F7/20
Filed: 1984-06-26
Abstract: PURPOSE:To inhibit the pattern defects caused by static electricity generated while a mask and an object to be exposed are closely contacted and exposed, by supplying ionized gas to between the mask and the object to be exposed so as to separate them from each other. CONSTITUTION:A motor mask 1 and a copy mask 2 are set respectively on packings 3a and 3b. Nitrogen gas is then supplied to closed spaces 7 and 8 so that said packings 3a and 3b are bent inwards. The surface of the mother mask 1 is thereby closely contacted with the surface of the copy mask 2. Light beams 20 are applied to these masks so as to expose them to light. By exhausting the nitrogen gas from the closed spaces 7 and 8, the mother mask 1 and the copy mask 2 are separated from each other. The closed space 6 is supplied at this time with nitrogen gas ionized by an ion generator 15, so that ions are showered upon the mother mask 1 and the copy mask 2. Static electricity is thereby removed from the surfaces of the masks, and therefore the adhesion of dust to the masks which would be caused by generation of static electricity can be effectively prevented.
