Patent JP-S6211327-A (JP)
Title: Radio relay system
Inventor: OZAKI TAKAYUKI
IPC: H04B7/15
Filed: 1985-07-09
Abstract: PURPOSE:To miniaturize a repeater by using a transversal equalizer of an intermediate frequency band so as to detect a digital modulation wave, controlling the equalizer to minimize a waveform distortion and to relay an equalized digital modulation wave. CONSTITUTION:For example, a multi-value orthogonal amplitude modulation (QAM) wave in a received microwave band signal is frequency-converted into an IF band a receiver 1, the noise component is reduced by an IF filter and an automatic gain control amplifier, the level is made constant and the result is fed to a transversal equalizer (T-EQL) 7. The IF band multi-value QAM wave where transmission distortion caused by, e.g., fading is equalized is frequency-converted by a transmitter 6 into a microwave, converted into a required level and sent to an opposite station. The control by the T-EQL 7 is performed so that the distortion of a base band signal obtained through the detection by an orthogonal detector 9 is minimized. Thus, the repater is miniaturized and the power consumption is reduced.

Title: Method for depositing material layer on substrate and plating system
Inventor: SIMPSON CINDY REIDSEMA
IPC: H01L21/288
Filed: 1998-05-14
Abstract: PROBLEM TO BE SOLVED: To provide an electroplating system which make the layers to be deposited in a plating treatment uniform and a method therefor. SOLUTION: This electroplating system 30 and method make it possible to improve the uniformity of the deposition of a conductive material or to enable the adjustment of deposition by enhancing the uniformity of the current density over the entire part of the surface of a semiconductor element substrate 20 during the plating treatment. A current density modifier 37 lowers the current density near the edge of this substrate. The adjustment to improve the uniformity of the plating, i.e., to increase the material for plating near the center of the substrate 20 is made possible by such lowering of the current density. The system enables such alteration as to remove the current density modifier on a structure 36 or remove this structure from the system without disassembling the parts of a head 35 at all.  The downtime of the apparatus is reduced, the life of the apparatus is prolonged and the number of particles is reduced by cleaning on site.

IPC: G03B13/36
Filed: 1981-09-24
Abstract: PURPOSE:To obtain an automatic focusing device which operates stably nearly within its focusing position range without deteriorating in response outside of said near focusing position range. CONSTITUTION:A focus arithmetic controlling circuit 10 processes photoelectric conversion signals of subject images reformed on solid-state image pickup elements 8 and 9 to detect the relative positions of said subject images, and thus obtains pieces of information on a front-focus, a rear-focus, and a focusing state, and the displacement position of a photographic lens from a focusing position, and also drives a motor 13 to output a servo signal x(t) based upon those pieces of information for the movement of the focusing position of the photographic lens 1. This servo signal x(t) contains an improper component (noise) transiently owing to camera shake, noise malfunction of the device, etc. A servo-control circuit 11 inputs the servo signal x(t) containing the noise, and then converts it into a servo signal z(t) removed from the noise to putting the automatic focusing device in stable operation.

IPC: F23N1/00
Filed: 1979-11-21
Abstract: PURPOSE: To prevent an exhaust purifying catalyst from being overheated, by attaching a fuel discharge controller to a fuel pump which is actuated when the catalyst temperature rises.  
     CONSTITUTION: As a power switch 2 is turned on, a transistor 7 is oscillated to excite a plunger driving coil of a fuel pump for fuel injection. A control transistor 11 and light emitting diode 12 are set in parallel to a thermal sensing element 14 attached to a catalyst in an exhaust system. As the catalyst is overheated, the diode 12 emits light which is transmitted to a light sensing resistor 9 to increase its resistance. This reduces a voltage through the coil 3 to turn off the plunger.

Abstract: PURPOSE:To remove a phase jitter interference component by allowing the output of a carrier phase control circuit to pass a fixed equalizer on which line equalizing characteristics obtained after the inserting point of a phase jitter factor are set up. CONSTITUTION:Data MODEM for deciding a signal point corresponding to a receiving signal point after removing an inter-code interference by an automatic equalizing means 10, removing a phase error and frequency offset by a carrier automatic phase control means (CAPC) 12 and then removing phase jitter by a phase jitter removing means 14 is utilized as an object. In this case, a phase jitter interference removing means 18 for removing a phase jitter interference component is provided following on the CAPC 12. Namely when the equalizing characteristic of a line generating phase jitter interference after the phase jitter inserting point is defined as C<-1>, the phase jitter interference component included in the output of the CAPC 12 can be removed by providing the means 18 with the equalizer 20 on which a line equalizing characteristic C is set up. Consequently, the phase jitter component generated in the transmission line in which the phase jitter exists can be removed.

Abstract: PURPOSE:To control economically the temp. in a blast furnace in front of the tuyere, by blowing CO2-contg. gas into the blast furnace through the tuyere. CONSTITUTION:Blast furnace gas discharged from the top of a blast furnace 2 is accumulated through a dust collector 1, cold water scrubbers 3, 4, and a silencer 6 into a tank. A portion of the blast furnace gas is led through a compressor 7 to an annular pipe line installed at the outer periphery of a blast furnace tuyere, and is blown into the furnace through a nozzle 10 while the gas quantity being controlled by a valve 14. Simultaneously, hot air is blown in from a hot stove 15 through a pipe 8. The CO2 contained in the blast furnace gas is brought into contact with red-hot coke, so that it is reduced and lowers the temp. in the furnace in front of the tuyere due to its heat-absorption. This method makes it possible to control the temp. in front of the tuyere in the furnace without blowing heavy oil or steam through the tuyere.
