Title: Optical character reader
Inventor: INOUE KEIICHI
IPC: G06K9/32
Filed: 1993-04-14
Abstract: PURPOSE:To accurately segment characters regardless of unfixed inclination of a carried slip. CONSTITUTION:The angle of inclination of the front end of the slip is detected by a front end inclination angle detecting part 3. The reference side position of a character segmentation object row is estimated based on the angle of inclination of the front end of the slip by a reference side position estimating part 4. The reference side position of the character segmentation object row is detected by a reference side position detecting part 5. The angle of inclination of the character segmentation object row is calculated in an inclination angle calculating part 6 based on the estimated reference side position of the character segmentation object row, the detected reference side position of the character segmentation object row, the reference side position of the row preceding the character segmentation object row, and the detected angle of inclination of the front end of the slip. A character segmenting part 7 corrects character position information of the character segmentation object row, which is given from a control part 9, by the angle of inclination of the character segmentation object row calculated by the inclination angle calculating part 6 to obtain the character segmentation position.

Title: Combustion control device
Inventor: KAWAMURA MITSURU
IPC: F23N5/00
Filed: 1989-04-28
Abstract: PURPOSE:To specify a room temperature detecting state without using a false resistor and to perform a combustion test with high efficiency by a method wherein according to the set state of a room temperature flag memory, a detecting room temperature is set to a given value in a set temperature range regardless of detection of a room temperature by a room temperature detecting element. CONSTITUTION:When a power source is turned ON by ON-operating room temperature set switches 5 and 6, a room temperature flag memory is set, and a set temperature is initially set to TA. When combustion is started, a timer is started to operate, a room temperature input is decreased to T0 to start a combustion motion. In which case, since TA is higher than T0, for example, a device in which a combustion amount is switched in two stages of high and low stages performs a HIGH combustion motion. When a timer counts a time t0, a room temperature input is changed from T0 to T1. A room temperature input exceeds the set temperature TA, a combustion amount is changed into LOW, and switching to a LOW combustion motion is effected. As noted above, a room temperature is changed in two stages with the elapse of a time, and according to the change of the room temperature, a combustion amount can be changed in 2 stages. Namely, there is no need to operate the room temperature set switches 5 and 6 in order to change a combustion amount.
