Patent JP-H03160214-A (JP)
Title: Supervising device for flame current
Inventor: TAJIMA KAZUHIRO
IPC: F23N5/24
Filed: 1989-11-20
Abstract: PURPOSE:To enhance the reliability and safety of the above device by a method wherein a voltage applied to a flame rod is changed over alternately to a DC voltage and to an AC voltage, thereby determining the normal or abnormal state of combustion and others. CONSTITUTION:While a DC voltage is applied to a flame rod 1, the voltage VA of a capacitor 18 exceeds a reference voltage VB, and an output from a comparator 21 becomes 'H'. On the other hand, when an AC voltage is applied, the voltage VA of the capacitor 15 becomes lower than the reference voltage VB, and the output from the comparator 21 becomes 'L'. The DC voltage (for one minute) and the AC voltage (for five seconds) are alternately applied to the flame rod 1, and normal or abnormal combustion is judged by comparing IF with S3 and D2 during the period of applying the DC voltage to issue an alarm or to control the stopping of combustion. Further, comparison between IF and S1 is made during the period of applying the AC voltage, and when IF is lower than S1, a ground fault is judged, and an alarm is issued to stop combustion. Furthermore, at the time of the lapse of five seconds, the output from the comparator 21 is read, and in the case where the output from the comparator 21 is not 'L', an alarm informing that the voltages are not normally changed over is issued, and combustion is stopped.

Title: Dry etching method
Inventor: TATSUMI TETSUYA
IPC: C23F4/00
Filed: 1991-10-22
Abstract: PURPOSE:To prevent the generation of etching residues due to SiSX silicon sulfide) in a method of performing a dry etching on a silicon material layer, whose sidewalls are protected with a sulfur (S) film. CONSTITUTION:When a polycrystalline silicon layer is etched using S2F2/H2O (vapor) mixed gas in a processing of a gate electrode, an etching progresses by the contribution of F*, S<+>, SF<+> and the like while a sidewall protective film consisting of S is formed and the gate electrode having an anisotropic form is formed. Here SiSX is generated in an etching reaction system, but this is immediately decomposed into Si(OH)4 and H2O added to the gas and is removed. Accordingly, the SiSX does never function as an etching mask and the generation of etching residues can be prevented. If a natural oxide film is ready-removed before the etching, a residue preventive effect is much more improved.

Filed: 1988-11-28
Abstract: PURPOSE:To prevent the deterioration of the performance of a CPU which is caused by a bus master except a CPU by stopping the replacement of caches in the case a cache mistake occurs when an access is given to a memory of a bus master except the CPU. CONSTITUTION:A cache replacement control means 6a controls the cache replacement when a bus master except a CPU 1 has an access to a cache 5 and produces a cache mistake. A connection switch means 8 decides whether the start of the means 6a should be instructed or not by the hardware.

That is, sensing is made to know whether the wheel speed condition is accelerative or decelerative, and the current reference wheel speed is calculated in accordance with the accelerative/decelerative tendencies at the previous run and before it. In case these two tendencies are the same as shown in the table, and if the current run is also the same (condition No. 1 or 8), it is considered that the current wheel speed reflects the real situation, and the value is adopted as the current reference wheel speed. If the current run differs from the previous (condition No. 2 or 7) even through the previous accelerative/decelerative tendency is the same as the one before it, a certain minor value B or B' is added to or subtracted from the previous reference wheel speed for the time being. Besides it, a filter as illustrated is provided.
