Title: Grille
Inventor: KOBAYASHI TOSHIHIRO
IPC: F24C3/02
Filed: 1999-08-17
Abstract: PROBLEM TO BE SOLVED: To prevent an unfavorable combustion of a grille burner from occurring by providing a draft generating burner, which accelerates the discharging of a combustion gas in a grille chamber by a draft force, in the initial stage of an ignition. SOLUTION: The combustion gas of a draft generating burner 61 raises the temperature of air in an exhaust chamber 71, and generates a large temperature difference between the upstream and the downstream of an exhaust port 70, and generates an upward draft force in the exhaust chamber 71. By the generation of the draft force, the combustion gas from a grille burner 63 is smoothly discharged to the outside of a grille chamber 60 through the exhaust chamber 71. At the same time, the generation of the draft force sucks in the outside air from an air introduction port 65 on the bottom surface of the grille chamber 60. The outside air is sucked into a cooling path 64, and is made to flow along the lower surface of a receiving tray 62 and cools the receiving tray 62. By this constitution, an unfavorable combustion of the grille burner 63 can be prevented from occurring.

Title: Load detector
Inventor: NAITOU KAZUFUMI
IPC: G01G3/14
Filed: 1983-12-08
Abstract: PURPOSE:To improve accuracy and durability, by providing strain gages made of an amorphous silicon material on the surface of a strain yielding body formed by fuzed quartz as a unitary body, and outputting an electric signal in proportion to the weight of a material to be measured. CONSTITUTION:Strain gages 5' made of amorphous silicon are provided on a strain yielding body 4' formed by fuzed quartz as a unitary body. Since the strain yielding body 4' is nonconducting, the strain gages 5' are directly deposited on the upper surface of the strain yielding body 4' by a chemical gaseous phase growing method. Thus a bridge circuit 10 is formed. When a material to be measured is supplied to a measuring hopper 3, the strain yielding body 4' is deflected, and each gage 5' receives a tensile load and a compressing load. The potential difference is yielded between output terminals by the change in resistance value of each strain gage 5' constituting the bridge circuit 10. Thus the weight of the material to be measured is detected. In this way, accuracy and durability are improved, and the measuring range of the strain yielding body 4' can be made wide.

Filed: 1994-09-28
Abstract: PURPOSE: To lessen the number of compensators to be installed for preventing the troubles in controlling which are caused by an on-delay of a three-phase inverter when the inverter drives an ac motor. CONSTITUTION: A three-phase/two-phase converter 31 converts three-phase current actual values output from a PWM inverter 4 into a d-axis current actual value ID and a q-axis current actual value IQ which cross at right angles. A d-axis current regulator 34 determines a d-axis voltage command value VD* from the deviation of the d-axis current actual value ID from the current command value ID*. In a similar manner, a q-axis current regulator 35 determines a control signal from the deviation of the q-axis current actual value IQ from the current command value IQ*. Only the q axis is provided with a q-axis compensator 36 and a q-axis compensating signal Vc output from the q-axis compensator 36 and the control signal output from the q-axis current regulator 36 are added by a q-axis adder 38 and the adding result becomes a q-axis voltage command value VQ*.  The d-axis voltage command value VQ* and the q-axis voltage command value VQ* are returned to a three-phase ac coordinate system again by a two phase/three-phase converter 37 and the PWM inverter 4 is controlled on those signals.
