Title: Device and method for providing background noise displaying operation in digital receiver
Inventor: REIMONDO JIEI REOPORUDO
IPC: H04B1/10
Filed: 1992-09-10
Abstract: PURPOSE: To allow a user to recognize the operating state of a digital receiver from background noise by providing a background noise generator for controlling the amplitude of its output, depending on a reception signal to the digital receiver. CONSTITUTION: An antenna 42, an RF section 44, a mixer 48 and a vocoder 50 in the receiver 40 configure a digital section. An audio amplifier 52, a final audio circuit stage 54 and an audio converter 56 configure an audio section. A receiver is provided with a variable amplitude noise generator 60, which gives a digital noise signal to the vocoder 50 via the mixer 48. Thus, the digital noise signal is mixed with a digital signal from the RF section 44 at the digital section to provide a background noise signal. The variable amplitude noise generator 60 is controlled by an output signal from the RF section 44, and the amplitude of the background noise is reduced in response, as an input signal strength is increased.

IPC: F23J3/00
Filed: 1993-10-27
Abstract: PURPOSE:To enable the most suitable jetting pressure to be attained when a soot blower is operated by a method wherein the jetted fluid pressure during the next operation of the soot blower is varied in the maximum variation range of difference between the steam temperature at the outlet of a boiler and a desired control value. CONSTITUTION:A calculator 2 receives a signal from a transmitter 1 for the steam temperature at the outlet of a boiler and calculates the difference of temperature from a rated value as a control value of the boiler outlet port temperature within a specified time after jetting from a sot blower or a deslagging device. The jetting pressure is set in advance in a stepwise manner according to the calculated maximum varying range and the set jetting pressure is stored in an internal memory in correspondence with the difference. Then, at the next jetting, the stored pressure value is fed to a pressure adjusting device 3 when the next jetting is carried out. A pressure adjusting device 3 receives this instruction, controls the degree of opening of a valve and sets the pressure of fluid in a system of a piping 12. With such an arrangement as above, the differences of the steam temperature and the steam pressure at the outlet of the boiler from the control values become minimums.

Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a solid-state image-pickup device whose power consumption is suppressed small, while adopting plural stages of source follower circuits. SOLUTION: A 15V reset voltage Vr is used for a power supply voltage Vod1 of a 1st stage source follower circuit 4 similarly to a conventional device, and this is due to a current flowing to the 1st stage source follower circuit 4 is as small as 200-300μA, and power consumption is not so much reduced even when a low power supply Vod1 is adopted for the source follower circuit 4. Since a current of 3-4mA flows in a 2nd stage source follower circuit 5, a low-power supply voltage Vod2 is adopted for the source follower circuit 5, and the power consumption that is a product of the current and the voltage is reduced thereby.
