Title: Frequency offset compensation circuit
Inventor: YOSHINO HITOSHI
IPC: H04B1/10
Filed: 1993-08-23
Abstract: PURPOSE:To estimate the frequency offset with high accuracy even under the occurrence of multi-path fading by interposing a transversal filter between an output of a differential coding circuit and an input to a correlation circuit. CONSTITUTION:A base band signal y(i) being a received complex envelope signal is subject to delay detection by a delay detection circuit 2 to provide an output of a signal z(i) to a correlation circuit. Furthermore, a differential coding circuit 5 outputs a differential code series m(i) to a transversal filter 8 based on a predetermined training signal outputted from a training signal generator 6. The correlation circuit 3 receives the signal z(i) and an output of the filter 8 to provide an output of a correlation signal (c), and a frequency offset (Fo) estimate circuit 4 outputs an Fo estimate signal DELTAomega based on the signal (c). A complex multiplier 7 multiplies the signal y(i) and the DELTAomega to compensate the Fo. Thus, the frequency offset is estimated with high accuracy even under the occurrence of multi-path propagation fading.

IPC: G03F1/84
Filed: 1984-10-05
Abstract: PURPOSE:To make it possible to inspect a pattern without generating a pseudo- defect, by comparing several picture element at a corner part of a model pattern with a pattern to be inspected, with said picture element as a dead zone. CONSTITUTION:A model pattern 18 is expanded into the two-dimensional image having 3X3 picture elements by using one-line delay lines 13 and a shift register 14. Then exclusive OR values 15 of the central picture element and the surrounding 8 picture elements of the 3X3 picture elements are computed. The results are added by an adder 16. The added result represents the number of the picture elements having the opposite color from the color of the central picture element among the surrounding 8 picture elements of the 3X3 picture elements except the central picture element. The added result is compared with a constant '4' by a comparator 17. When the result is 4 or more, a '1' is outputted. When the result is 3 or less, a '0' is outputted. A signal 18b' indicating whether the dead zone is present or not is obtained. A signal 18a', which indicates the black and white pattern in synchronization with the signal 18b', is outputted from the shift register 14. Thus the model pattern, in which the dead zone is provided in the picture elements at the corner part, can be obtained.

Abstract: PURPOSE:To apply positioning at a high speed with high accuracy by detecting the period of vibration generated when a mobile body is accelerated, and setting the arrival speed so that the time requiring for acceleration is an integral number multiple of the vibrating period, thereby decreasing the residual vibration of a machine system. CONSTITUTION:The set position and the arrival speed of the mobile body 1 is set to a position speed voltage converter 6 and a servo motor 4 is started and accelerated. On the other hand, a vibration sensor 10 detects the vibration of the mobile body 1 and a period T of the vibration waveform is inputted to an arithmetic unit 12. A rotary angle or an angular velocity of the motor 4 from a position detector 8 is inputted to the arithmetic unit 12 and a time (t) from the acceleration start to the present time is inputted from a clock 13 at the same time. The arithmetic unit 12 makes operation so that the time reaching the set speed is an integral number of multiple of the synchronism T, the result is inputted to the converter 6 to correct the set speed. As a result, the residual vibration of the machine system of the mobile body 1 is decreased and attenuated earlier so as to conduct acceleration and deceleration and positioning at a high speed with high accuracy is attained.

Title: Diesel fine particle eliminator
Inventor: TERADA MAMORU
IPC: F01N9/00
Filed: 1982-12-01
Abstract: PURPOSE:To prevent fusion of trap by detecting inside temperature of trap and performing feedback control of secondary air supply thereby maintaining the inside temperature of trap below fusing temperature. CONSTITUTION:During regeneration, temperature in trap 8 is measured by temperature sensors 24, 25 to perform temperature control by means of ECU29. When the temperature in trap is below fusing temperature of catching member T3, secondary air supply is stopped by closing a solenoid valve 22 to suppress combustion thus to lower temperature in trap 8 and when it will drop below self-combustionable temperature T4, said solenoid valve 22 will open to feed secondary air to start self-combustion of particulate. In such a manner, combustion will continue for predetermined time under the temperature between T3 and T4 to burn the particulates completely. Consequently the temperature of trap 8 is maintained below fusing temperature to cause no fusion of trap 8.

IPC: H04M1/60
Filed: 1984-10-05
Abstract: PURPOSE:To set automatically a speech reception sound volume at an optimum level in a telephone application mode by varying a waiting time in response to the speech reception sound volume. CONSTITUTION:A reception signal is supplied to a speaker 4 via a hybrid circuit 1, a variable gain amplifier 2 and a speech reception power amplifier 3. While voices are supplied to the circuit 1 via a mike 7, a mike amplifier 6 and a variable gain amplifier 5. In a waiting mode the outputs of a speech reception rectifier circuit 8 and a speech transmission rectifier circuit are reduced. At the same time, a threshold value circuit 21 delivers the signal having a high level. In such a case, a changeover switch 24 is turned off and therefore the circuit system of a comparator 10 is separated from a point X. Then the value of a variable resistor 25 for the control of the waiting state varies in response to the actuation of a speech reception variable attenuator 26. Thus the DC potential is varied at the point X. The resistor 25 is cut off with the input of a sound signal. Then the circuit system of the comparator 10 is connected to the point X.

Abstract: PURPOSE: To prevent worsening of the appearance caused by running of a rib where sipes are formed. CONSTITUTION: A second rib 18 is divided into a plurality of lands by sipes 22, and tall lands 28 and less tall lands 30 are arranged alternately. The angle αformed by a tread 28A to the sipes 22 is set to 100deg., and the lands 28 are formed trapezoidal. The taller lands 28 receive a greater pressure when grounded than that which the less tall lands 30 receive. Because the lands 28 are set so that the swell-out amount of the side wall 28B when it is inclined and receives a compression enlarges, so that the side wall 28B swells out largely along with reception of a large compressive force, and thereby the sipes 22 are put in tight attachment. During contacting with a road surface, the lands 28 and the ones 30 are consolidated substantially so that a grounding behavior the same as a rib not divided by sipes 22 is exhibited, which achieves suppression of the heel-and-toe wear.
