Title: Combustion control device
Inventor: OKAMOTO HIDEO
IPC: F23N5/20
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the generation of abnormal noise directly after ignition, especially during cold time ignition by changing a burner combustion volume into a combustion volume to be decided by a combustion volume decision making means after the lapse of a specified time since an ignition detection means detects the ignition of said burner. CONSTITUTION:When ignition is detected by a flame rod 18 at time 't', a combustion volume Qi during a specified ignition time called for until the temperature of a burner 2 is stabilized, is maintained as illustrated in a solid line A. Therefore, this construction makes it possible to conform the characteristic frequency f2 of a supply section to the characteristic frequency of a combustion section 10 even right after the ignition when the temperature of a burner 2 for a burner plate 12 or the like fails to rise to a satisfactory extent, thereby preventing the generation of noise. Then, at time t3, the combustion volume is changed into a combustion volume to be decided based on a controller 71 or the like. A blower 25 and a proportional control valve 61 are controlled from the above data.

Title: Noise shaping circuit
Inventor: SUGIHARA TORU
IPC: H03M7/00
Filed: 1992-10-31
Abstract: PURPOSE:To prevent the occurrence of hunting phenomenon based upon a limit cycle by detecting that an input signal becomes a DC value (including '0') and setting up a value fed back to a quantizer to '0'. CONSTITUTION:An input signal from an input terminal 11 is sent to a DC detector 17 and whether the input signal is a DC value including '0' or not is detected. When the input signal is a DC value including '0', all coefficeint values outputted from a noise filter 16 are controlled by a control signal outputted from a DC detector 17 so as to be switched to '0', so that a feedback value from the filter 16 to an adder (subtractor) 12 becomes '0'. When noise feedback value to a requantizer 13 becomes '0', an n-bit input signal from an input terminal 11 is extracted from an output terminal 14 after executing only cut-back to m bits. Consequently the occurrence of a hunting phenomenon can be prevented.

IPC: H01S3/10
Filed: 1994-12-20
Abstract: PURPOSE: To form an image with a different resolution by changing the shape of the optical path of a laser beam by superposing a slit on the path by the movement of an arm. CONSTITUTION: An arm 25 has a slit 24 for specifying the shape of the optical path of a laser beam 15.
