Abstract: PURPOSE:To simply and accurately enhance estimating accuracy of the air-fuel ratio of respective cylinders by calculating a value CX hat (k) from an estimated state variable X hat (k), and judging a converging condition of an observer by comparing it with output Y(k). CONSTITUTION:A single air-fuel ratio sensor 40 is arranged with every exhaust system collected part 24 of a multicylinder internal combustion engine 10, and the air-fuel ratio of an input air-fuel mixture of respective cylinders is estimated from the output. Behavior of an exhaust system is identified by state equations I and II [A, B and C are a matrix of (nXm)] in which the air-fuel ratio of the respective cylinders is set as input U(k) and the air-fuel ratio of the collected part is set as output Y(k), and is estimated by an X hat (k) from a state equation III (K is a gain matrix) in which an observer is constructed by setting the input U(k) as a prescribed value and the output Y(k) is used as input and the air-fuel ratio of the respective cylinders is set as a state variable X. A value CX hat (k) is calculated from an estimated state variable X hat (k), and it is compared with the output Y(k), and a converging condition of the observer is measured.

Title: Vehicle sensor
Inventor: FUJIMOTO TAKUYA
IPC: G08G1/052
Filed: 1990-07-10
Abstract: PURPOSE:To improve the accuracy of both speed measurement and sensing for the presence or absence of a vehicle by setting the directivity of a first receiving antenna narrower in the direction of movement and the directivity of a second receiving antenna wider in the direction of movement. CONSTITUTION:A receiving antenna 11 of an antenna part 2 has the directivity covering a lane 3. On the other hand, first and second receiving antennas 12/13 cover a lane 1, the first receiving antenna 12 has the directivity limited in the direction of movement, and the second receiving antenna 13 has the directivity broadening the cover range in the direction of movement. Namely, since the directivity of the movement direction of the first receiving antenna 12 is narrow, the range including a Doppler frequency decreases and the accurate speed measurement can be performed. Since the directivity of the second receiving antenna 13 is wide, the presense or absence of a vehicle can be surely and accurately sensed without generating pulse crack. Thus, the antithetic performance of high speed accuracy and high sensitivity can be simultaneously satisfied.

Filed: 1997-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent the program of different specification from erroneously being down-loaded in updating for down-loading the individual programs generated for the unit of different specification through the use of a general boot loader and a flash memory. SOLUTION: If a password collation mode is set in down-loading the program (S440: YES), a model/country identification password is received (S450) and it is collated with a password stored in the pertinent area of a main program area. When they are not matched, received data is read (S460-S480). The password collation mode is set when initial loading is not completed. When initial loading is not completed, the password collation mode is not set and the program and the password are read without collating the passwords. They are written in the pertinent areas (S510-S560).

IPC: H03K23/52
Filed: 1981-11-16
Abstract: PURPOSE:To decrease the number of required elements, by using a flip-flop circuit controlling clock signals supplied to a transfer gate depending on the state of input. CONSTITUTION:When an input Dn is ''H'', a clock -CK' is given to an AND  circuit AND11 to invert an output Qn via transfer gates TG11, TG12 and inverters I11-I13. When the input Dn is ''L'', a clock signal being the -CK' is stopped to hold the output Qn. As a result, the input signals can be frequency-divided by a half with less number of elements. In constituting an n-frequency division circuit concretely, the number of gates can be decreased from the conventional numbers of 7Xn into 6X(n+1).

Abstract: PURPOSE:To obtain high transfer efficiency and to prevent the failure and skipping of a transfer by using a contact type electrifier, and electrifying the opposite surface of a transfer material carrier while a transfer material pressurizing a photosensitive drum from the opposite face of the transfer material carrier. CONSTITUTION:In the contact part of the photosensitive drum 1 and the transfer material P, the electrifying roller 3 of a contact electrifier is rotated while the transfer material carrier 2 is pressed on the photosensitive drum 1 from the inner periphery of the carrier 2 to obtain the contact, so that a toner image T on the photosensitive drum 1 comes into contact with the transfer material P with proper pressure. this case the electrifying roller 3 positively electrifies the inner periphery of the transfer carrier 2 to form a transfer electric field. The negatively electrified toner image T on the photosensitive drum 1 is transferred and held on the transfer material P on a transfer part. Thus, the contact state of the toner image T on the photosensitive drum 1 and the transfer material P is stabilized, and uniform contact is obtained.

Title: Method to measure spin-lattice relaxation period
Inventor: CHIYAARUZU RUSHIAN DAMOORIN
IPC: G01N24/08
Filed: 1994-08-05
Abstract: PURPOSE: To measure the spin grid relaxation time of a subject by using the sequence of radio frequency puses and magnetic field gradient pulse in a magnetic resonance imaging device. CONSTITUTION: By first the longitudinal spin magnetization is inverted by inverting RF pulses, and secondly by using a sub-sequence in which a series of detecting RF pulses 130 is included, the spin grid relaxation time is determined by detecting the recovery of the magnetization. While the inverting pulse is applied to the whole of a tested body, the detecting pulse is applied only to a selected part of the subject. In the case of measuring the spin grid relaxation time of moving blood, the blood in a detected area is replaced for the respective detecting pulse by the movement of blood, so that the measurement accuracy is heightened and after one inverting pulse, many detecting pulses can be detected. Accordingly, the renal function in the individual kidneys can be evaluated by using the sub-sequency in a living body.

Title: Pattern matching device and its learning system
Inventor: SEKOE HIROAKI
IPC: G10L15/16
Filed: 1988-07-22
Abstract: PURPOSE:To cope with the fluctuation of a feature vector itself by correcting the element of a standard vector in accordance with the product of the difference of the signal of each input unit and the corresponding standard vector and the output of an intermediate unit except the immediately higher rank ones kept under the direct control in a learning state. CONSTITUTION:The input vectors ai are received by 7 input units of an input frame 10, and the difference yli between the vector ai and a standard vector bki<n> is obtained via an intermediate frame 20. A selection unit 30 selects the minimum value of an output group yli, and an output unit 40 calculates the sum total of the outputs of a selection layer to output the pattern difference (z). The minimum value of the difference (z) shows the recognizing result. In a learning state, the total sum of the selection layer is approximated by the product arithmetic and the output Z(n) can be differentiated with the vector blki<n>. Thus the standard vector element blki is corrected with the value corresponding to the product piymi (mnot equal to l) of the difference between the signal aki received from each input unit and the corresponding element blki and output of an intermediate group except the higher rank intermediate units kept under the direct control and contained in a higher rank intermediate frame.

Abstract: PURPOSE:To make whole network not stop even if a trouble occurs in one station or a transmission line by transmitting and receiving a signal, by separating the transmission lines of a ring type and a bus type according to a situation. CONSTITUTION:The signal like a picture signal, etc., required to be processed at high speed, is transmitted through the medium of the ring type transmission line, and the signal such as a state monitor signal, etc., is transmitted through the medium of the bus type transmission line 4. In this case, if it is assumed that the trouble occurs in a work station 13 for instance, the work station 12 sends communication data to the transmission line 32 for output at low speed. This communication data is received by the work station 14 through the bus type transmission line 4 and further through an input output line 34. Hereafter, because the data goes round through a ring type LAN. the work station 12 receives a response from the work station 11.
