Patent JP-S61240028-A (JP)
Title: Combustion safety device
Inventor: KOMAI YUKIRO
IPC: F23N5/10
Filed: 1985-04-16
Abstract: PURPOSE:To enable to close the gas circuit before the generation of CO by a method wherein the range of oxygen density to close the gas circuit under oxygen deficient state is reduced by forming a V-shaped groove on a primary flame port at the end of a circular tube. CONSTITUTION:The fuel jetted from a nozzle 7 mixes with the primary air passing through air holes 5 and forms the primary flame at the primary flame port 2 by being backed up with the secondary air passing through auxiliary air holes 6. A photo couple 8 produces the electromotive force of about 22 mV normally or when the oxygen density is 21%. However, under oxygen deficient state or when the oxygen density becomes lower, the primary flame port 2 can not hold the existing residual flame due to a V-shaped groove 11 formed on the primary flame port 2 and the electromotive force quickly becomes small. Thus, in the case that the separation voltage of an attraction valve, which opens the gas circuit with the electromotive force of the photo couple 8, is 4-8mV for example, if the oxygen density falls within the narrow range such as 18.2 17.6%, the gas circuit is brought into closed state. Consequently, the danger of the generation of CO, which occurs under the oxygen density of about 17%, in an appliance, is eliminated.

Title: Zoom lens
Inventor: NAGAOKA TOSHIYUKI
IPC: G02B13/18
Filed: 1993-04-07
Abstract: PURPOSE:To obtain a zoom lens of inner-focusing system of small size and with high optical performance and with a variable power rate of around 8 by using a leans whose one surface is aspherical surface in a fourth lens group with positive refracting power. CONSTITUTION:The fourth lens group contains at least the lens whose one surface is aspherical surface, and a second lens group is comprised of at least lenses. Focusing on an object point at short distance is performed by drawing out a third lens group on an object side, and also, the condition of D2T/fr>0.08 can be satisfied. Where, D2T is a gap between the second lens group and the third lens group at a telephoto end when an object point is located at an infinite-point, and fr is the focal distance of the whole system at the telephoto end. It is undesirable to perform the focusing on the object point in close range in the case where D2T/fr is less than 0.08 since it is required to increase the refracting power of the third lens group, and the various kinds of aberrations generated in the group are increased, and aberration fluctuation when the focusing is performed is increased.

Title: Load voltage compensating device
Inventor: KUWABARA HIDEO
IPC: H02J3/12
Filed: 1984-04-20
Abstract: PURPOSE:To increase a response speed and to supply stabler DC electric power by using a semiconductor switch as a switch for short-circuiting or resetting one or plural series-connected semiconductor rectifying elements. CONSTITUTION:If a load 14 varies abruptly into a heavy load and the terminal voltage Eb across a storage battery 5 drops until a load voltage E attains to its lower limit El, a voltage detecting device 13 detects that and supplies an on- command signal to the driving device of a transistor (Tr) 15. Consequently, the Tr15 is turned on to short-circuit diode series bodies 6-10, so the load E applied to the load rises up to Eb, thus compensating said drop. When the Tr17 is on, on the other hand, a floating discharge mode is switched to a uniform charging mode and the voltage Eb rises abruptly to its upper limit value Eu, and then the device 13 detects that and turns off the Tr15. Consequently, the voltage E applied to the load drops from Eb, so its rise is suppressed.

Title: Markless color control method in printer
Inventor: SEYMOUR JOHN C
IPC: B41F31/02
Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To eliminate pulse repetition time by matching/comparing an acquired image array with a target image array and communicating with an ink controller by obtaining a square solution for a matrix linking regulation of the ink controller with variation of color value through a sensitivity coefficient. SOLUTION: A video camera 68 picks up a print image and a controller 70 calculates an image value to generate an image array. The color array of a picked up image is matched, at first, with the color array of a target image and then a color value is compared, in units of pixel, with the color value of the target image thus determining a desired variation of color value. A matrix including each of a plurality of pixels for associating the ink key regulation with the measured variation of color value is thereby generated. In an inking system model, a sensitivity factor for linking the ink key regulation with the variation of color value is obtained and a least square solution is determined before generating a set of ink key regulation.
