Title: Gas equipment
Inventor: KOBAYASHI SHIRO
IPC: F23N1/02
Filed: 1986-10-17
Abstract: PURPOSE:To attain an automatic keeping of a constant combustion capability of a main burner by a method wherein a heating amount signal corresponding to a heating calorie of a sense burner is inputted, the inputted value is compared with a reference value set by a gas equipment in advance, an impressed current for an electromagnetic valve is varied to decrease or increase a degree of opening of the electromagnetic valve. CONSTITUTION:A heating calorie signal generated at a heating calorie sensor device 40 heated by a sensing burner 30 to which a specified amount of gas branched from a supplying passage 20 is supplied during operation of the gas equipment corresponds to a heating calorie of supplied gas. A control device 50 has an input of this heating calorie signal, compares it with a reference value defined in accordance with a design specification of the gas equipment in advance, impresses an electric current corresponding to a result of comparison to a solenoid of an electromagnetic valve 100, makes a degree of opening of the electromagnetic valve 100 low if a value of the heating calorie signal is high to decrease a gas supplying volume, and in turn if a value of heating calorie signal is low, it makes a degree of opening of the electromagnetic valve 100 large to increase a gas supplying volume. With this arrangement, even if the gas heating calorie is varied, a combustion capability of the main burner 10 is automatically kept constant so as to be a reference value of the gas equipment.

IPC: H01L21/205
Filed: 1989-09-27
Abstract: PURPOSE:To suppress the generation of a slip line by forming a thin vapor growth layer first on a semiconductor substrate, using SiH4 as reactive gas when forming an Si vapor growth film, and next forming a specified vapor growth film at a low temperature corresponding to the growth temperature of SiH4 by the use of Si-H2Cl2. CONSTITUTION:A semiconductor wafer W is placed on the susceptor 7 within a reactor 1 shielded from outside air, and a specified amount of N2 gas is ejected from a nozzle 8 so as to substitute N2 gas for the air within the reactor 1. Next, a specified amount of H2 gas is ejected from the nozzle 8 so as to substitute H2 gas for N2 gas, and high frequency power is given to a high frequency coil 31 so as to induce and heat the susceptor 7. When the wafer W is heated up by conduction and radiation to a temperature at which SiH4 grows, H2 being carrier gas and SiH4 being reactive gas are ejected from the nozzle 8. After that, the gas inside the reactor 1 is replaced with H2 gas, and this time SiH2Cl2 is ejected as reactive gas from the nozzle 8. This way, after the growth by SiH4, immediately the surface is covered with SiH2Cl2.

Title: Pattern collating device
Inventor: OODAN ETSUROU
IPC: G06K9/00
Filed: 1983-12-28
Abstract: PURPOSE:To make it possible to collate also a pattern having a ground pattern on its background by collating the ground pattern with the pattern and removing the ground pattern from the collating pattern. CONSTITUTION:A document 1 is read out by a reader 10 and the read data are sent to a ground pattern positioning/removing means 11. A data control device 12 separates only a partial area 4 including a print of a seal 3 and stores the area 4 in a picture memory 13. The control part 12 positions a background part 5 on the ground pattern previously stored in a registered ground pattern memory 14. If the ground pattern 6 can be collated in the background part 5, the whole ground pattern of the partial area 4 including the print of the seal 3 can be found out by forecasting it from the positional relation of the repeated pattern of the ground pattern 6. Thus, the pattern of the seal print from which the ground pattern is removed can be obtained by subtracting the ground pattern from the partial area 4 stored in the picture memory 13.
