Patent JP-S55162521-A (JP)
Title: Burner
Inventor: INUI YOSHIAKI
IPC: F23D11/40
Filed: 1979-06-01
Abstract: PURPOSE: To produce a heating effect and a combustion flame which are always stable, by providing a space between a head spoke part and flame ports in a device in which secondary air is introduced into the center of the combustion flame.  
     CONSTITUTION: A mixed gas flow, which contains air and evaporated or atomized liquid fuel or gas fuel, is conducted to a burner head 23 and burned in a device. A pressure equalizing plate 25, a porous flame port plate 26 and a keep plate 27 are protruded forth so that a space is defined between a head spoke part 33 and flame ports 45, 46. As a result, vortical negative pressure caused at downstream to the spoke part 33 of a head body 24 does not reach the flame ports 45, 46 and the flowing velocity of the mixed gas gushing from the ports is stabilized. According to this constitution, combustion is stabilized even if the combustion quantity is low or an excess air ratio is small.

Title: Power source
Inventor: OKATSUCHI CHIHIRO
IPC: G05F1/10
Filed: 1991-03-11
Abstract: PURPOSE:To reduce in size, to eliminate a loss during operation and to obtain a power source having a high efficiency by providing a reactor in which an input current becomes an attenuated resonance current at the transient time of inputting a DC voltage, and further providing a protective circuit for operating chopper means when the voltage of a smoothing capacitor becomes a predetermined voltage or lower. CONSTITUTION:A charging current of a smoothing capacitor 4 becomes an attenuated resonance current by an operation of a reactor 22 when a breaker 2 is closed, and a maximum value of the applied current is limited to a value decided by a circuit constant. A voltage V4 of the capacitor 4 is raised to twice as large as a maximum V1, and attenuated by power consumption of a DC/DC converter 19, a loss of a main circuit. An overvoltage detector 31 operates a chopper 20 when the value of the voltage V4 is a predetermined voltage or lower. Thus, the operation of the chopper is inhibited while the voltage of the capacitor is raised at the transient time, thereby reducing a stress of MOSFETs 7, 8.

Title: Control device of continuously variable transmission
Inventor: MINAGAWA YUSUKE
IPC: F16H61/21
Filed: 1994-04-07
Abstract: PURPOSE:To prevent the stick-out of a vehicle by adjusting the transmission speed in changing and controlling the transmission ratio of a continuously variable transmission to be small to suppress the rapid release of the inertia energy of the engine due to the delay in operating the booster when the boost pressure condition of the engine is over the prescribed value. CONSTITUTION:The line pressure to be fed to a driving pulley cylinder chamber 20 and a driven pulley cylinder chamber 32 generates the holding force sufficient to prevent a belt 24 from being slipped against the rotational moving force to be applied to the belt 24 while the pulley ratio is changed and controlled by the input with the rotational angle of a step motor as the control quantity to pulleys 16, 26. When the pulley ratio, i.e., the transmission ratio is changed and controlled to be small as the vehicle speed is increased or the throttle opening is reduced, the line pressure to be fed is reduced. When the boost pressure condition of the intake air is over the prescribed value, the transmission speed to the up-shift of the continuously variable transmission is adjusted to be small to suppress and prevent the transmission shock such as the stick-out of the vehicle.

Title: Method for grinding roll of rolling mill
Inventor: IDEUE KAZUO
IPC: B21B28/02
Filed: 1984-04-10
Abstract: PURPOSE:To eliminate the need for a driving device of grinding body and to simplify its construction by specifying the angle of a grinding body in case of rotating a roll, in an on-line roll-grinding method performed by pressing the rotating grinding-body against the roll surface. CONSTITUTION:A cylindrical grinding body 3, such as a whetstone, is pressed against the roll surface of a roll 1 to be ground. The body 3 is freely rotatably supported on a supporting bed so that its rotating axis Y intersects the axis X of roll 1 at an angle theta with respect to the axis X. Further, the supporting bed is moved parallelly to the axis X along a fixed guide beam. Accordingly, the body 3 can be moved parallelly to the axis X. Hereupon, when the body 3 is pressed against the roll 1 surface while rotating the roll 1 at a peripheral speed VR, the peripheral speed VG of the body 3 becomes smaller than the peripheral speed VR and a relative slip VS is produced in the Y-axis direction, because the body 3 rotates on its own axis but intersects the axis X at the angle theta. Here, as the body 3 is supported impossibly to move in the Y-axis direction, the roll 1 surface is ground in accordance with the slip VS.

Title: Solenoid valve for controlling ink jet
Inventor: IWASAKI KIYUUHACHIROU
IPC: B41J2/175
Filed: 1980-05-26
Abstract: PURPOSE:To prevent dripping or reverse flow of ink by a method wherein a plunger effecting the opening and closing operations of a flow path is constituted so as not to be provided with a braking force upon moving into one direction while so as to be provided with the same upon moving into the other direction in the solenoid valve controlling ink jet. CONSTITUTION:When the pressure of an accumulator is arrived at a predetermined value, an electric current is flowed through a coil 14 in the solenoid valve and the plunger 16 is lifted up whereby a piston 17 is moved upward. At this moment, a pressure in a cylinder 18 becomes the same as the atmospheric pressure because the air is released to the outside thereof by the upward movement of a ball 18c, therefore, no braking force is exerted to the piston 17 and paths 11a1, 11a2 are communicated instantaneously thereby causing no dripping of the ink. Next, when the coil 14 is deenergized, the piston 17 tries to move downward by the force of a spring 20, however, because the ball 18c is closing a vent port 18a, the inside of the cylinder 18 becomes to a negative pressure, the piston 17 is lowered slowly, the ink pressure of a head 6 is lowered gradually and the air will never flow reversely.
