Abstract: PURPOSE: To easily and accurately diagnose a limiting current type oxygen sensor for any abnormality by applying, to the oxygen sensor, a diagnostic voltage in a voltage range in which a positive or negative current flows, and comparing the detected current value with a predetermined criterion for failure. CONSTITUTION: A CPU s48a , when it is judged that a predetermined time has elapsed since the previous abnormality diagnosis, applies a negative voltage Vn to an oxygen sensor 26 as a diagnostic voltage, and compares a negative sensor current In detected by a sensor current detecting circuit 45 with a predetermined criterion Inc for abnormality (a current value within a predetermined range containing at least zero, e.g. 5mA) when In >Inc , it outputs an abnormality signal to an engine control part 49 to turn on an alarm light 29 and to interrupt air-fuel ratio feedback control, and when In <Inc , the CPU waits for a predetermined time (e.g.  100ms) and then compares a negative current In at that time with the criterion Inc again, and when In <Inc , it judges that the sensor 26 is normal, and executes air-fuel ratio detection, and when In <=Inc , it judges that the sensor 26 is abnormal, and outputs an abnormality signal to the control part 29.

Filed: 1993-06-10
Abstract: PURPOSE:To quicken the retrieval speed by referencing a retrieval data table provided with a picture for retrieval command and a learning function so as to transfer a picture with a deep relation to the retrieval command picture to a display memory section. CONSTITUTION:When an entry section 12 is used to provide a retrieval command, each of data corresponding to the picture in a retrieval table 14 is revised and when a retrieved picture is in existence in display memory sections 3-5, a changeover section 6 is switched to connect a relevant frame memory to a D/A converter section 7. Then the retrieved picture data are read from the frame memories 3-5 and displayed via the D/A converter section 7. Whether or not the retrieval number of times for each retrieved picture reaches a predetermined number is checked and when the predetermined number of times is reached, the data of the picture are revised. When the retrieved picture is not in existence in the display memory section, the relevant picture is transferred from a picture storage device 1 to, e.g. the memory 3 and the retrieved data are read from the memory 3 and displayed. A succeeding picture number or the like is referenced from the retrieval table 13 and the picture is transferred to the frame memories 4, 5.

Filed: 1991-06-11
Abstract: PURPOSE:To prevent the occurrence of idle wiping during the time when a vehicle is making a stop by surely detecting in a simple manner that the vehicle is making a stop in regard to a wiper control device. CONSTITUTION:It is judged by the presence of a parking signal generated when the parking brake is applied whether or not a vehicle is making a stop (step 3). When it is judged that the vehicle is making a stop, a control threshold value T1 for the accumulated value SIGMARp of rain drop pulses outputted from a rain sensor is set to one greater than a threshold value T2 which is set when it is detected that the vehicle is running. By this constitution, the sensitivity of wiper operations is lowered when the vehicle is making a stop (step 4 and 5).

Title: Signal transmitter
Inventor: KODAMA TOMOKO
IPC: H04L1/22
Filed: 1991-06-12
Abstract: PURPOSE:To switch a line while the quality of a transmission signal is kept by starting the transmission of a standby line when the quality of the transmission signal of an active line is degraded and switching the line when synchronization is taken. CONSTITUTION:When a bit error rate reaches a prescribed rate or above, as soon as a line switching signal is sent to a line switching device 10 and a frame synchronization detector 9, the signal transmission in a standby line is started. Then the detector 9 implements frame synchronization based on a transmission signal sent through the standby line and after the frame synchronization in the standby line is confirmed, the switching device 10 is used to switch the line. Since the active line and the standby line are switched between a transmission frame and a frequency, the active and standby lines are switched without causing error correction disabling state of the signal caused when the switching is implemented in the frame of the transmission signal.

Filed: 1990-05-29
Abstract: PURPOSE:To minimize space of an automatic travelling cleaner by providing a turnover switching element for turning in response to outputs of a detecting means a moving direction of a travelling device into advancing direction when a forward operation force is applied, and into retiring direction when a rearward operation force is applied, and a current control switching element directly connected to the turnover switching element. CONSTITUTION:A motor 14 drives a travelling device 12 in normal and reversed directions and a detecting means 9 detects whether operation force is applied in forward or rearward direction. When forward operation force is applied, normal and reversed direction turnover switching elements 25 and 26 are switched to drive the travelling device 12 in forward direction, and when rearward operation force is applied, the elements 25 and 26 are switched to drive the device 12 in rearward direction. When the travelling direction is reversed, the turnover switching elements 25 and 26 are switched, and immediately after the reversing, current is controlled to be small by a single current control switching element 27. By this constitution, heat generation of the elements can be restricted so that a radiation plate is not needed, whereby space can be minimized.

Abstract: PURPOSE:To mount and demount a grinding wheel, keeping a dynamic balance device installed, by installing two rollers in integral revolution each of which contacts individually an outer wheel and inner wheels and generates a revolution difference and installing weights which are shifted by the revolution difference and allowing a fixing tool for the grindstone to be exposed through an opened hole at the center part of a housing. CONSTITUTION:When two rollers (24a, 25a) and (24b, 25b) which can be revolved integrally are allowed to contact an outer wheel 11 and inner wheels 13a and 13b, the turning moment of the outer wheel in revolution which is installed onto a housing 10 which integrally revolves with a grindstone 1 is transmitted to the inner wheel which revolves freely for the outer wheel through each roller. A revolution difference is generated between the outer and inner wheels because of the diameter difference. Weights 20a and 20b are shifted by utilizing said revolution difference, and stopped at the position where vibration is less, and dynamically balanced. Further, when the grindstone is mounted/demounted, a fixing tool 4 for the grindstone is operated through an opened hole 10a at the center part of the housing, with a dynamic balance device installed.

Title: Production of substrate for oxygen sensor element
Inventor: KANBE YOSHITAKA
IPC: G01N27/41
Filed: 1988-06-07
Abstract: PURPOSE:To reduce cost and to prevent the generation of the deformation, crack, etc., of a heater part by using metal powder which is oxidized by calcination to form an insulating layer and using metal powder paste which forms the insulating layer. CONSTITUTION:A slurry is prepd. by mixing a binder, solvent, plasticizer, and deflocculant with zirconia powder. A zirconia green sheet 21 is produced from this slurry. The paste consisting of Al powder as the metal powder is then coated on the sheet 21 to form an Al powder layer 22. A Pt paste layer 23 is formed on the layer 22. The sheet 21 formed with the layer 23 and the layer 22 is then dried, degreased and calcined. The layer 23 constitutes the heater layer 23a and the sheet 21 is sintered to constitute a solid electrolyte layer 21a after the degreasing and calcination. On the other hand, the layer 22 turns to alumina as the Al is oxidized and the insulating layer 22a is formed between the layer 23a and the layer 21a. The layer 23 and the sheet 21 can be calcined simultaneously under the same conditions and, therefore, the production cost is reduced and the deformation, crack, etc., of the heater part are eliminated.
