Title: Method of neighboring channel suppression
Inventor: ANDOREASU RIYUNGERAA
IPC: H04B1/12
Filed: 1992-03-27
Abstract: PURPOSE: To compensate the influence of attenuation of an intermediate- frequency filter and a transmission line on a momentary amplitude by individually distortion generated on the signal path according to the influence of attenuation generated during transmission and an intermediate-frequency filter. CONSTITUTION: A digital PLL circuit 20 is tuned to the carrier of a desired signal and a digital PLL circuit 22 is tuned to the carrier of a fault signal, i.e., an adjacent channel. A base band signal is demodulated to obtain an estimated value of a phase ϕ1 of the desired signal on one output side 24 of the circuit 20 and an estimated value of a momentary amplitude a1 of the desired signal on the other output side 26. On one output side 28 of the circuit 22, an estimated value of a phase ϕ2 of the fault signal is extracted and on the other output side 30, an estimated value of a momentary amplitude a2 of the fault signal is extracted. Then components of the fault signal and desired signal are obtained through the remodulation of circuits 32 and 34 according to the respective estimated values. The signal components can be subtracted from the base band signal by coupling means 36 and 38.

Abstract: PROBLEM TO BE SOLVED: To provide a position detecting device, with which a very stable position detection is conducted compared with a conventional device, a magnetic recording device and an optical system and a lens having an aperture, which are applied to these devices. SOLUTION: Opening sections 111 and 112 are provided to make the sizes of the optical return paths from a disk 107 to optical detectors 108L and 108R larger than the sizes the optical return paths from a light source 101 to the disk 107.

Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To obtain a high speed common buffer switch by using a wavelength to specify a memory element to which a packet is written among a plurality of memories being composed of a buffer memory so as to realize the high speed buffer memory. SOLUTION: Packets received at input ports 1500 are transferred to a wavelength converter 1100. The wavelength converter 1100 converts the received packets into respective lights with specific wavelengths according to wavelength information transferred from a controller and transfers the lights to a wavelength multiplex distributor 1200-1. The wavelength multiplex distributor 1200-1 transfers a plurality of the received packets with different wavelengths to a plurality of memory elements 1300. Each memory element 1300 stores only the packet with a predetermined wavelength among the packets transferred from the wavelength multiplex distributor 1200-1. Wavelength selectors 1400 extract a packet with a wavelength instructed from the controller among packets transferred from a wavelength multiplex distributor 1200-2 and output the packet from an output port 1600 in the case of output.

IPC: B01D53/04
Filed: 1988-03-24
Abstract: PURPOSE:To increase the rate of recovery of product gas by successively and repeatedly carrying out adsorption, desorption, cleaning with slightly adsorbable gas (product gas), pressure equalization, recovery under pressure applied with desorbed gas and pressure accumulation with product gas in three or more adsorption vessels. CONSTITUTION:Raw gas is pressurized by a raw gas pump A and sent to a vessel 1, where readily adsorbable gas is adsorbed and removed and product gas is drawn out. The internal pressures of the vessel 1 and a vessel 3 after desorption and cleaning are equalized. The vessel 1 is evacuated by a vacuum pump B to desorb the adsorbed gas and cleaning is carried out by allowing product gas to flow through the vessel 1. After a pressure equalizing stage, pressure is applied to the vessel 1 with desorbed gas to carry out a recovering stage. Product gas is then introduced into the vessel 1 to carry out a pressure accumulating stage.

Title: Toner concentration detector
Inventor: FURUICHI MASAYOSHI
IPC: G03G15/08
Filed: 1979-06-12
Abstract: PURPOSE:To reduce the leakage of magnetic flux and save magnetic shield covers by providing a barrel-form path to allow the passage of the developer to the toner concentration detector and winding a coil to the foregoing passage. CONSTITUTION:A coil 12 is wound to a barrel-form passage 2 through which the two-component type developer passes, and a magnetic core 14 which forms the magnetic path together with the developer in the passage 2 is provided on the outer side of the passage 2. With such constitution, the coil 12 is wound on the barrel- form passage 2 and therefore not only the distribution of the magnetic flux is averaged but also approximately the whole of the magnetic flux having passed through the developer passes the external magnetic path, hence the leakage magnetic flux is extremely less. Consequently, even if the detector is installed without any magnetic shield cover, it is hardly affected by the presence of the carriers on the outer side of the barrel-form passage 2.
