Title: Lateral resist control device for picture image formation device
Inventor: INMIYA TAKEHARU
IPC: B41J13/00
Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To shorten time to correct a position of a sheet material in the cross direction. SOLUTION: A first sheet material is moved to a specified position by detecting its position in the cross direction (ST6) while carrying the first sheet material (ST5). Moving quantity (correcting quantity) at the time is memorized (ST7), and while carrying sheet materials after a second one (ST9), they are moved to the same position in the cross direction as the first one (ST10). In the case when the position in the cross direction is different from the previously carried sheet material (NO of ST11), moving quantity of the sheet material is re-memorized (ST7), and while sheet materials thereafter are carried in accordance with the re-emorized moving quantity (ST9), they are moved to the same position in the cross direction as the first one (ST10). Consequently, it is possible to shorten positional correcting time in the cross direction of the sheet materials after the second sheet.

Title: Negative pressure controlling valve
Inventor: NAITOU MICHIKATSU
IPC: F02B1/04
Filed: 1981-06-19
Abstract: PURPOSE:To effectively control the negative pressure in a diaphragm chamber in accordance with th state of engine load by a method wherein a valve holding member equipped between the diaphragm chamber and a chamber open to the atmosphere is adjustably supported by a plurality of balance springs and a moving rod. CONSTITUTION:When engine load increases, a coil 42 is excited through a load sensor 45 and a operational processing circuit 46 in order to apply an attractive force to a gap 44. Accordingly, even under the condition that the negative pressure in the diaphragm chamber is low, the force of the spring 34 surpasses that of the spring 35, resulting in shifting the moving rod 36 downward, lowering the valve holding member 32 and communicating the diaphragm chamber 26 to the chamber open to the atmosphere 39. Consequently, when the pressures in both the chambers 26 and 39 are equal to each other, the valve holding member 32 is raised by means of the spring 35 and the diaphragm chamber 26 is made vacuum for the setting of negative pressure by means of a vacuum pump 31. In other words, the setting of negative pressure can be performed in accordance with the state of engine load.

Title: Damping device
Inventor: NOMICHI TOSHIYUKI
IPC: E04H9/02
Filed: 1989-04-14
Abstract: PURPOSE:To dynamically absorb wave energy in a form of elastic deformation as well as to enhance a damping rate against fluid by providing a baffle plate rotatably against the wave direction of the fluid for the fluid of a storage tank with an open fluid surface, and thereby connecting a weight with the baffle plate via an elastic support means such as a rotating support cylinder and the like. CONSTITUTION:When a structure 1 oscillates horizontally to the directions as shown by arrow heads C and D by earthquakes, wind and the like, fluid 5 starts to wave in the directions as shown by the arrow heads C and D in such a way as to be synchronized with oscillation so that the oscillation of the structure 1 is absorbed by wave energy. In the second place, when the fluid 5 starts to wave to the directions as shown by the arrow heads A and D, a baffle plate 10 is rotated by wave energy to the directions as shown by arrow heads A and B via a support shaft 6. In this case, when the baffle plate 10 is tried to be rotated to the direction A, the baffle plate 10 is acted by force to the direction B because of the inertia of a weight 11 provided through the rotating support cylinder 9 of a spring member so that the waves of the fluid 5 are restrained by that amount while wave energy is concurrently being concumed as elastic deformation energy accompanied with the elastic deformation of the support cylinder 9, so as to be damped. The same is true even when the baffle plate 10 is rotated to the direction B.

Title: Vibration damping of gas-turbine engine bucket
Inventor: MERUBIN BOBO
IPC: F01D5/26
Filed: 1992-04-16
Abstract: PURPOSE: To maintain sliding engagement of a damper pad with a bevelled platform surface so as to dissipate vibrational energy in a bucket by preventing the reactionary force applied by the platform to the damper from generating rotational moment. CONSTITUTION: Pads 36, 38, 40 engage their opposite bevelled platform surface 26 when a damper 30 is propelled into a V-shaped groove by centrifugal force during the rotation of a rotor disc. As in the case of the relative bucket motion shown by arrow heads 48, 50, the load applied to the pad 38 (arrow head 54) and the load applied to the pad 40 (arrow head 56) are oriented to a common point 58 on a vector 44, no rotational moment acting on the damper 30 is generated. On the contrary, as in the case of the relative bucket motion shown by arrow heads 60, 62, the load applied to the pad 36 (arrow head 66) and the load applied to the pad 40 (arrow head 68) are also oriented to a common point 70 on a centrifugal line, no swinging moment acts upon the damper 30.  Thus, it is possible to maintain sliding engagement of the damper with the bevelled platform surface and dissipate vibrational energy.

Filed: 1989-04-14
Abstract: PURPOSE:To shorten the fire spread time and hence prevent the discharge of vaporized gas by providing a secondary air hole which is open to the upper end of a secondary air chamber except for a fire spread section. CONSTITUTION:The air sent from a combustion fan 20 is divided into three systems which comprise a vaporizer air which enters a mixing chamber 15 passing through a vaporizer 11, a primary air which enters the mixing chamber 15 passing through a primary flow straightening hole 13, and a secondary air which is ejected from a secondary air hole 18. The vaporized gas generated in the vaporizer 11 is mixed with the vaporizer air in the mixing chamber 15, and produces a premixed air, which is ejected from flame holes 16. The premixed air ejected from a flame hole 16A is ignited by the discharge of an ignition plug 21, thereby forming flames. As a fire spread section 19 is surrounded by the flame holes 16 and the secondary air holes 18, a stagnation area 22 is generated. The premixed air and the secondary air flow into this stagnation area 22. Therefore, the first ignited flames are brought into contact with the adjoining premixed air in a fire spread section, thereby igniting the premixed air instantaneously. Since then similar fire spread continues, which makes it possible to shorten fire spread time and prevent the discharge of exhaust gas as well.

Filed: 1988-04-19
Abstract: PURPOSE:To improve fuel consumption and to enable excellent cleaning of exhaust gas, by a method wherein a change in the fluctuation width of the rotation speed of an internal combustion engine is detected, and according to the change, the air-fuel ratio of the internal combustion engine is varied. CONSTITUTION:A detecting means M1 detects the fluctuation width of a rotation speed during non-load running of an internal combustion engine. A varying means M2 varies an air-fuel ratio so that the fluctuation width of the rotation speed is decreased. In this case, a change in the fluctuation width of the rotation speed is detected by a detecting means M3. When a change in the fluctuation width of the rotation speed is produced, based on the change, the varying means M2 is controlled by a first control means M4 so that an air-fuel ratio is brought into the lean side or the rich side. Meanwhile, when there is no change, the varying means M2 is controlled by a second control means M5 so that an air- fuel ratio is brought into the lean side. This constitution improves fuel consumption during non-load running, and cleans exhaust gas in an excellent state.
