Title: Control device of gas appliance
Inventor: ADACHI IKURO
IPC: F23N1/00
Filed: 1995-11-09
Abstract: PROBLEM TO BE SOLVED: To facilitate the switching and checking operation of the minimum and maximum current values of a proportional valve, and to surely return the control condition to the original one. SOLUTION: The regular combustion control is realized after ignition of a burner 1 is detected, and when the switching operation from the off-condition to the on-condition of a minimum combustion forced switch or a maximum combustion forced switch is detected during the combustion, the current value of a governor proportional valve 33 is switched to the current value corresponding to the minimum combustion or the maximum combustion. When each switch is not returned to the original condition after each switching operation is detected, the governor proportional valve 33 is returned to the regular combustion control in 20 minutes after the final switching operation is detected.  Because the current value is switched by the switching from the off-condition to the on-condition, a worker can easily judge whether or not the operation for switching is completed, and surely check the pressure. The combustion control is returned to the original condition even when the returning operation of each switch to the original condition is neglected after the work.

Abstract: PURPOSE:To cool the abnormal-temp. spot and to prevent the ignition of coal by measuring the surface temp. of a coal heap with a non-contact thermometer set on a movable water sprinkler and sprinkling cooling water over the heap when the measured temp. exceeds a set value. CONSTITUTION:Coal is stacked by a stacker (not shown in the figure) into a coal heap 1 on the ground in a coal yard. A water sprinkling nozzle 6 is fixed to a body 5 traveling on a rail 3 provided on the ground to form a water sprinkler 4, which is freely moved in the longitudinal direction of the heap 1. A non-contact thermometer 8 such as an IR thermometer is fixed to the sprinkler 4 through a support 9.

Title: Production of spherical ceramic sintered compact, and spherical ceramic sintered compact
Inventor: NIWA TOMONORI
IPC: C04B35/64
Filed: 1999-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain a spherical ceramic sintered compact having reduced defects and producible in a high efficiency and to provide a method for producing the sintered compact. SOLUTION: Ground powder for molding is spherically attached and stuck to the circumference of a molding nucleus body 50 while the molding nucleus body 50 is being rolled on a ground powder layer 10k for molding in a rotating granulation container to give a spherical molding body 80. Consequently the density of a stuck layer 10a of the molding ground powder growing around the molding body 80 can be extremely raised and the formed stuck layer 10a has reduced defects such as pore and cracks caused by bridging of powder particles. The spherical molding body 80 is baked.  Consequently, the obtained spherical ceramic sintered compact comprises a nucleus part derived from the molding nucleus body 50 at the central part of the sintered compact distinguishable between it and an outer layer part derived from the stuck layer 10a having high density and a few defects when a section passing through approximately the central part of the sintered compact is polished, enlarged and observed. The polished surface is made into a sintered compact structure showing the texture to give the objective spherical ceramic sintered compact having a small ratio of defect formation on the surface part, a high density and a high strength.

Title: Switching power supply circuit
Inventor: YASUMURA MASAYUKI
IPC: H02M3/28
Filed: 1999-10-14
Abstract: PROBLEM TO BE SOLVED: To reduce power loss in a switching element without causing increase in the size of circuit scale. SOLUTION: Clamp circuits 2A, 2B which are to be provided in a self- oscillating resonance type converter are formed of Schottky barrier diodes DSBD1, DSBD2 and resistors RD1, RD2. Consequently, since the waveforms for the drive current IB supplied to the switching elements Q1, Q2 can be formed as substantially ideal waveforms where an inverse current, for example, during turning off of the switching elements Q1, Q2 is increased, the power loss due to the switching elements Q1, Q2 can be reduced by shortening the accumulation time t stig and descending time tf of the switching elements Q1, Q2.
