Patent JP-S6037869-A (JP)
Title: Scanning device
Inventor: KODERA MASAHIDE
IPC: H04N1/19
Filed: 1983-08-10
Abstract: PURPOSE:To detect surely minute information on a medium by adopting the constitution that the main scanning direction and the sub-scanning direction are crossed obliquely for a line sensor. CONSTITUTION:An image sensor is moved as shown in symbols j-1-j+2 in case of sub-scanning, as a result a device, e.g., a photodetector section (c) on the image sensor is moved sequentially to positions c', c'', c''' (or conversely). Thus, when the image sensor conducts scanning from the position j-1 to the j+2, a minute line P is detected as an independent picture element in the order of different photodetector sections (e), c', a'' and Y'''. Thus, the information such as lateral lines of the Ming type Kanji (Chinese character) narrower than the conventional scanning line is not suppressed in case of binary-coding at the post- stage.

Title: Detection of gas
Inventor: KODA HIROSHI
IPC: G01N27/12
Filed: 1988-06-13
Abstract: PURPOSE:To detect a specific gas with a piece of gas sensor by using the differences in the response speeds of the gas sensor to the respective gaseous components in a gaseous mixture. CONSTITUTION:The gas sensor 2 has a heater and a thin SnO2 film and has the response speeds varying with the gas to be detected in the gaseous mixture and the other gases. The breathing air is sucked by a specific delivery pump 12 via a detector 10 from a mouthpiece 8 when the breathing air is blown into the sensor. The output of the gas sensor 20 is inputted via an A/D converter 14 to a differentiation circuit 16 and a distributor 20. A memory 22 stores the output V0 before the start of contact with the breathing air, the output V1 of the 2nd second after the start of the contact, the output V2 of the 5th second, and the output V3 of the 10th second in the sampling period of a timer 18. An arithmetic circuit 24 for detecting the concn. of CH3SH (concn. of bad breath) determines to CH3SH from V1-n(V<3>-V2) and divides the same by the output V0 in the air, thus making the detection based on the output change from the inside of the air. In the formula, (n) is an integer.

Title: Method for detecting rate of change
Inventor: SANO TAKESHI
IPC: G01D1/16
Filed: 1990-06-04
Abstract: PURPOSE:To prevent erroneous determination in a case where a value has temporarily and suddenly changed due to a disturbance, etc. by a method wherein in determining a rate of change, whether or not the rate of change is excessive is determined depending on whether or not a difference between current data and a plurality of previously sampled data is a determination value of an amount of change or higher. CONSTITUTION:After measurement data is sampled with predetermined time intervals, the sampled data are sequentially stored and also the currently sampled data are compared to a predetermined number of data which have been stored to obtain the differences. If there is a difference which is larger than a defined determination value of an amount of change among the differences, determination is made such that a rate of change of the measurement data is excessive. Thus even if the measurement data temporarily and suddenly changed within the determination value of the amount of change due to a disturbance, etc., the amount of change will not be determined to be excessive, and also it is possible to quickly determine that the rate of change is excessive as to measurement data which actually change suddenly.

Title: Deciding method for print starting position of dot printer
Inventor: YONEZAWA SETSUO
IPC: B41J29/42
Filed: 1981-09-16
Abstract: PURPOSE:To eliminate the displacement of a print starting position by comparing and judging the stored content at the prespacing time with the counted pulse value at the spacing time for printing, thereby selectively deciding a print starting pulse. CONSTITUTION:An output signal from a comparison judging arithmetic unit 57, a print timing signal from a dot sensor 48 and a home signal from a home sensor 51 are supplied to a main controller 56 of a CPU, which controller 56 thus processes printing data fed from external equipments and generates drive signals of a printing head 5, a drive motor 8 and a clutch solenoid 21 in a mechanism. A counter 58 is cleared by a fall of the signal from the sensor 51, thereby starting the pulse counting of the print timing signal of the sensor 48. When a blank pulse is applied to the print timing signal, a stop signal is fed from the controller 56, thereby stopping the counting operation of the counter 58. Thus, the stored value of the registor 59 is compared with the magnitude of the  counted value of the counter 58 by the unit 57, thereby deciding the print starting position.

Filed: 1999-05-26
Abstract: PROBLEM TO BE SOLVED: To directly select an interrupt processing routine according to hardware by unnecessitating any polling processing by software or the rewriting of software. SOLUTION: An interrupt controller INTCTR successively accepts interrupt signals from devices A, B, and C, and outputs an interrupt request signal IRQ and interrupt generating device information INTSEL, and starts the acceptance of the next interrupt by waiting for an acceptance signal IRQACK.
