Patent JP-H01312309-A (JP)
Title: Propagation burner
Inventor: KIMURA JUNICHI
IPC: F23C15/00
Filed: 1988-06-09
Abstract: PURPOSE:To upgrade combustion efficiency by stretching a heating wire over the span where the flames are propagated in the center of a straight pipe-shaped combustion chamber, and designing a combustion system so that the power may be supplied to said heating wire when a discharge gas side flame detector detects a flame, propagating the flames so that they may go and return, avoiding direct extinguishment of the flames. CONSTITUTION:A mixed gas which is mixed within a reference end mixing chamber 4 in a straight pipe-shaped combustion chamber 1 is ignited by an ignition heat source 5 and starts combustion from the tip side. When an exhaust side flame detector F2 detects the flames, a change over switch S is turned on so that the electric current flows to a heating wire 2 from a power supply V. To heat the wire, a flame stream flows to the upper stream side against an inflow pressure of the mixed gas, thereby propagating the flames going on. When an air supply side flame detector F1 detects the flames, the change over switch S is adapted to turn off so that the mixed gas may flow to the down stream side, burning in the tip section, thereby propagating the flames going on. The ignition by an ignition heat source 5 is only available during starting. After that, the flames are continuously propagated automatically between the flame detectors F1 and F2, thereby upgrading the combustion efficiency.

Title: Sintered compact for tool and its production
Inventor: TSUNODA HIDEO
IPC: C04B35/10
Filed: 1989-06-07
Abstract: PURPOSE:To provide a sintered compact for tool capable of low-temp. sintering an causing neither breaking nor abnormal wear of tip at the time of high-speed cutting by adding specific amounts of monoclinic ZrO2 having specific grain size to Al2O3. CONSTITUTION:This sintered compact for tool is produced by sintering a powder mixture consisting of 1-10wt.% monoclinic ZrO2 having <=1000Angstrom  average grain size and 90-99wt.% Al2O3. Since ZrO2 enables the low-temp. sintering of Al2O3 and is uniformly dispersed in the surface of Al2O3 grains, and further, at the time of sintering, ZrO2 absorbs impurity components in Al2O3 and also forms solid solutions together with Al2O3, the grain boundaries are firmly bound. Moreover, when the average grain size of ZrO2 is >=1000Angstrom , uniform dispersion into Al2O3 grains cannot be attained, and further, when the additive quantity of ZrO2 is less than 1%, grain boundary binding power is insufficient, and, on the other hand, the effect caused by increased amount of ZrO2 cannot be produced when it exceeds 10%. The above sintered compact can be attained even by normal pressure sintering in the air and can show superior characteristics, e.g. in high-speed matching of steel in particular.

Title: Cooked condition sensing device for electric oven
Inventor: TANABE TAKESHI
IPC: F24C7/02
Filed: 1988-06-10
Abstract: PURPOSE:To control a detection of temperature and heating means with a simple mechanical parts by a method wherein an increased temperature of a psudo-load means acting as a psudo-load against a food of which temperature is increased due to absorption of a micro-wave is converted into a variation of a shape of shape memory alloy member and a micro-switch is operated with it. CONSTITUTION:As material suitable for a micro-waver absorbing member 1, silicon carbide and ferrite and the like are applied and its temperature is increased by absorbing a micro-wave. The micro-wave absorbing member 1 may become a pseudo-load means against a food and then a temperature of food can be acknowledged without making any direct check of the temperature of food if its temperature is found. A magnetron 5a to which an electrical power is supplied may radiate a microwave and the food within an oven is heated. Simultaneously, the micro-wave absorbing member 1 may absorb a part of the micro-wave and its temperature is increased. As a temperature of food reaches a cooking finished temperature, a shape memory alloy member 3 is bent due to temperature of micro-wave absorbing member 1, and then a micro-switch 4 is depressed to terminate a heating of food. With the arrangement above, it is possible to mount a cooking finished condition sensing device in a less-expensive electronic oven.

Abstract: PURPOSE:To develop paint function without being effected by the capacity of a buffer register by a method wherein the start point of the next color printing is stored in a system part and subsequently outputted to a printer main body to perform the color printing of a closed region at every unit divided coloring region. CONSTITUTION:When color printing is started, the data of a divided printing region 3A is supplied to the buffer register of the PRT part 5 from a system part 6 to be stored therein. Since the region 3A is in an initial state, the data of the next divided printing region 3B is supplied to said buffer register to be stored therein. Thereupon, in a step ST6, the searching of the color printing part within the closed region 1 in an one-dot line and the color printing to the detected color printing part are applied from the internal conversion point whose Y- coordinates are uppermost among three internal conversion parts 7A, 7B, 7C. Next, it is judged whether color printing is finished in a line lower by one dot. Then, it is judged whether buffer capacity is finished in the next dot line and, when the buffer capacity is not yet finished (in the case of NO), a dot line to be subjected to color printing is lowered by one line and, thereafter, color printing is again returned to the step ST6.

Filed: 1998-05-26
Abstract: PROBLEM TO BE SOLVED: To suppress the occurrence of shading in a solid image pick-up device with a micro lens. SOLUTION: In a device, a plurality of optoelectric conversion elements 54 are provided on a light reception surface 52 on a semiconductor substrate 50, and a micro lens 10 is provided on the optoelectric conversion elements 54. Then, in the spherical surface of each micro lens 10, the curvature of the center side of the light reception surface 52 is larger than that of a peripheral side. Therefore, incident light that gradually inclines from the center of the light reception surface 52 toward the periphery can be greatly retracted in the direction of the center of each of the optoelectric conversion elements 54 by each micro lens 10. As a result, the reduction in the quantity of light at the optoelectric conversion element 54 being located at the peripheral side of the light reception surface 52 can be improved, thus suppressing the occurrence of shading.
