Title: Filter apparatus
Inventor: IWAI TADASHI
IPC: B01D29/62
Filed: 1981-05-29
Abstract: PURPOSE: To generate no clogging due to a filter material when backwashing is carried out and to prevent the outflow of the filter material by a method wherein a porous plate is provided to a backwashing water discharge port and light weight particles are interposed between the porous plate and a filter material layer.  
     CONSTITUTION: In backwashing process, valves 11, 13 are opened and valves 10, 12 are closed and washing water is supplied from the lower part of a filter tower 1 by a backwashing pump 7 and passed in an upwardly directed stream to fluidize a filter material layer. In this case, simultaneously with the passing of washing water, light weight particles 5 floated in water are concentrated toward a washing water discharge port and formed into a fixed layer by pressing the same to a porous plate 8 by washing water. When the speed of washing water is increased in the backwashing process, a filter material accompanied and raised by washing water is collected by the fixed layer comprising light weight particles and can be prevented from being discharged from the washing water discharge port. In addition, by attaching a differential pressure detector detecting the differential pressure of the fixed layer, the flow speed of washing water can be controlled according to the differential pressure.

Filed: 1988-04-04
Abstract: PURPOSE:To recover a read error even if a wiggle phenomenon occurs by instructing a retry action based on the detected read error, deciding that the retry action is repeated for the prescribed number of times and executing a prescribed write action. CONSTITUTION:For recording signals, the signals transmitted to a recording and reproducing amplification circuit 8 through a disk controller 9 by the instruction of a CPU10 are impressed on a magnetic head 1 and are recorded in a recording medium 2.

Next, the positioning device 4 is controlled, which positions again the magnetic head 1 to the original track position so as to make the head to execute the write action. Thus, the read error can be recovered even it is wiggle phenomenon occurs.

Title: Radio communication system
Inventor: ISHIBASHI TAKANOBU
IPC: G01S13/79
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain a stable system capable of demodulating data with a low error rate by transmitting data at the first communication frequency and the second communication frequency different from the first one from a radio communication device to a radio communication medium. SOLUTION: A radio card reader writer 100 operates on a clock of a frequency fp, transmits electric power to a radio card 200 by electric power transmission waves (frequency fp), and transmits data by data communication waves (frequency fd). The frequencies fp and fd are set so as to satisfy the relation fd=fp/k(1<k: integer). In addition, letting a distance of transmission be L and the velocity of light be c, fp satisfies the relation fp<<(kc/16L). By this, it is possible to operate the radio card 200 on the clock of frequency fp of the radio card reader writer 100. Therefore, as there is no need for specially incorporating a PLL circuit in the circuit in the radio card 200, the simplification and formation into one chip of a circuit configuration become easy.

IPC: G01J5/14
Filed: 1981-05-29
Abstract: PURPOSE:To detect the invasion of an object having a temperature difference in the background to a heat sensing region of a pyroelectric element, by connecting one end of a pyroelectric element to an amplifier, comparing a part of an output with a comparator and feeding back an integrated value of the output of the comparator to another end of the pyroelectric element. CONSTITUTION:An FET21 is connected to one end of a pyroelectric element 1, an amplified output is inputted to a transistor (TR) 31, a compared output is integrated with an integration circuit 4 using a resistor (R) 41 and a capacitor (C) 42, and the integration output is fed back to another end of the element 1. Thus, if the element 1 has a temperature rise, the output of the FET21 tends to drop, but the impedance of the TR31 is increased, the operating point potential of the element 1 is increased with the R41 and C42, and the output of the FET21 is not greatly changed from a prescribed state of the temperature of the element 1. Thus, the invasion of an object having a temperature difference in the background to the heat sensing region of the element 1 can surely be detected by suitably setting the time constant specified by the R41 and C42.
