IPC: B03C3/68
Filed: 1987-09-30
Abstract: PURPOSE:To optimize the voltage of a discharge electrode by inputting the output from the temp. sensor and/or pressure sensor provided to the casing of the title electrostatic precipitator to a signal converter, and inputting the output from the signal converter to the voltage controller for a dust collecting electrode. CONSTITUTION:The temp. sensor 8 and/or pressure sensor 8' are provided at the predetermined position of the casing 1 of the electrostatic precipitator. The output from the sensors 8 and 8' is inputted to the signal converter 11, and the output from the signal converter 11 is inputted to the voltage (current) controller 10 for the dust collecting electrode 9. The temp. and/or pressure in the precipitator used under high temp. and/or high pressure are detected, and the corona discharge voltage is controlled based on the detection value. As a result, the variations in the discharge voltage are controlled, when the precipitator is operated at the temp. or pressure greatly different from the rated operating temp. or pressure, especially when the temp. or pressure is increased and decreased in the starting and stopping of the precipitator, or when the precipitator is operated at low temp. or low pressure in the low-load operation. Consequently, the dust collecting function of the precipitator can be stably maintained.

Title: Output limiter for output amplifier of d-class bicmos hearing aid
Inventor: SHIRO MIRATSUZO
IPC: H03F3/183
Filed: 1993-09-30
Abstract: PURPOSE: To reduce power consumption and to design a hearing aid with higher performance for a hard limiter which is provided between the output drive transistor of a D-class amplifier and a pulse width modulator. CONSTITUTION: This limiter 31 achieves operation by controlling the duty cycle of the output of the pulse width modulator, directly corresponding to the size of a voltage appearing at both terminals of a load output transducer 16. Pulse modulated(PWM) signals are compared with the output of a pair of one-shot circuits (single pulse generators). In the case that the positive pulse or negative pulse of the PWM signals is shorter than a one-shot pulse, the PWM pulse is replaced with the one-shot pulse. Thus, the maximum value and minimum value of the duty cycle of the PWM signals are set and thus, the positive and negative values of a corresponding output voltage are limited.

Abstract: PURPOSE:To prevent an unfixed toner image from scattering and to obtain a copy image of high quality having no image disorder by discharging transfer paper which is separated from a photosensitive drum electrostatically and gradually by using a conveyance assisting belt which has a potential gradient. CONSTITUTION:The conveyance assisting belt 20 is formed of a single layer of a conductor, a support roller 21 nearby a fixing device 17 is so driven for rotation that the conveyance assisting belt 20 and photosensitive drum 11 are equal in speed, and support rollers 21 and 22 are applied with voltages from power sources 23 and 24 so as to give the conveyance assisting belt 20 the potential gradient. The transfer paper 18 is discharged electrostatically and gradually according to the potential gradient while conveyed by the conveyance assisting belt 20, and then guided by a guide plate 25 and inserted into the fixing device 17. Here, the guide plate 25 has its surface made of a nonconductive material and is arranged so that no abrupt influence is exerted upon the electrostatic charging potential of the transfer paper 18. Consequently, the abrupt potential gradient is eliminated to eliminate the oscillatory scatter of toner on the transfer paper 18 and then eliminate the image disorder, thereby improving the resolution.

Title: Radio communication equipment
Inventor: MIYAZAKI SHINICHI
IPC: H04B1/40
Filed: 1987-09-28
Abstract: PURPOSE:To correct a reference oscillator by a reception high frequency signal by detecting a data signal included in a high frequency signal inputted to the receiver so as to discriminate whether or not the high frequency signal is an object reception high frequency signal and using a narrow band filter so as to limit the band of the intermediate frequency signal given to a comparator. CONSTITUTION:When the object reception high frequency signal is inputted to an input terminal 1 and it passes through the narrow band filter 12 while being converted into a 2nd intermediate frequency signal, the data signal included in the received high frequency signal is detected by a data detection circuit 13 and its detection signal is sent to a control circuit 14. The control circuit 14 changes a phase difference detection signal into a DC voltage and output it to a reference oscillator 4 to correct the output frequency of the reference oscillator 4 based on the object reception high frequency signal inputted to the input terminal 1. In this case, since the narrow band filter 12 blocks the input of other high frequency signal to a phase comparator 10 when the frequency is at the outside of the band of the narrow band filter even when the other high frequency signal having a higher electric field level than the object reception high frequency signal is given, the frequency correction is to be implemented consecutively based on the object reception high frequency signal only.

Title: Memory access system
Inventor: KATAGIRI YOSHIHIKO
IPC: G06F12/02
Filed: 1992-09-14
Abstract: PURPOSE:To gain fast memory access by shortening the setup time of an address for the memory access. CONSTITUTION:An address register 135 holds a value which is one larger than the address of last memory access by a request source 100. When the request source 100 starts accessing a memory, a comparator 140 compares an address sent out by the request source 100 with the contents of the address register 135. When the comparison result indicates a coincidence, the request source 100 ends the memory access. After the memory access, the address register 135 increases its holding contents. Consequently, the memory access to successive addresses can be gained at a high speed.

Abstract: PURPOSE:To enhance reliability by preventing the emission of an erroneous signal, by a method wherein a piezoelectric body is held between a pair of electrodes and another one electrode is further provided in a side receiving pressure contact force and impact force from the outside so as to hold a definite distance from the surfaces of said electrodes. CONSTITUTION:When matter which has kinetic energy equal to or more than a definite level collides with an isolation electrode 3, a part of the isolation electrode 3 provided under tension is depressed to the side of an electrode 2 and, simultaneously with the contact of the surface of the isolation electrode 3 with the electrode 2, the surface of a piezoelectric body 1 is struck and piezoelectric charge is generated in the piezoelectric body 1. This piezoelectric charge transfers to the electrode 2 and the isolation electrode 3 and is detected from electrode terminals 5, 5' as voltage. This detected voltage is determined by the value of the piezoelectric charge. Therefore, the voltage corresponding to the magnitude of impact can be detected and, when a small quantity of sand is fallen, no voltage is generated. By this method, the emission of an erroneous signal is prevented to make it possible to enhance reliability.
