Title: Handwritten character recognition system
Inventor: MIFUNE TOSHIMI
IPC: G06K9/62
Filed: 1987-04-13
Abstract: PURPOSE:To properly calculate the difference of a character by extracting the feature quantity of each dictionary character by using end point position information and stroke point motion information on each dictionary character, and calculating the difference between an input character and the dictionary character by using the feature quantity. CONSTITUTION:The feature of a dictionary pattern is extracted automatically from the dictionary pattern and the input character and dictionary character are compared with each other by an evaluation function calculated from the detection result. The dictionary character is the standard in the same category and a featured part can be detected from the dictionary character. This part is weighed and then when another character is inputted, matching can be evaded. Consequently, the function for evaluation of respective part is changed according to whether or not the part is featured, thereby calculating the difference of the character properly.

Title: Denitration method of combustion waste gas
Inventor: OGINO YOUZOU
IPC: B01D53/60
Filed: 1983-05-20
Abstract: PURPOSE:To obtain the desired denitration efficiency by controlling the amt. of a waste gas to be supplied to a CO oxidizing tower in accordance with the CO concn. in the waste gas to control the temp. of the waste gas at the inlet of a denitration reactor. CONSTITUTION:The waste gas of a sintering machine A is introduced into a wet type desulfurization apparatus C and desulfurized. Then the gas preheated by passing through a heat exchangers D is introduced into a CO oxidizing tower F wherein the gas is heated to a temp. necessary for the denitration, and then introduced into a dry type denitration tower G to undergo denitration. At this time, as the temp. necessary for denitration can not be obtained if the CO concn. is low, a fuel gas contg. CO is introduced into a gas pipe 1 on the upstream side of the CO oxidizing tower F. Reversely, as the temp. is increased abnormally if the CO concn. is high, the flow rate of the waste gas passing through the CO oxidizing tower F is controlled by by-passing a part of the gas into a bypass pipe J. The by-passed waste gas joins the waste gas after passing through the CO oxidizing tower F at the upstream side of a thermometer K.

Title: Constant voltage diode
Inventor: TAGUCHI YASUO
IPC: H01L29/866
Filed: 1986-04-18
Abstract: PURPOSE:To manufacture a stable constant voltage diode by a method wherein a PN junction in narrow depletion layer width is provided in a region isolated from a surface oxide film while the constant voltage value is decided by the breakdown voltage in the depletion layer part. CONSTITUTION:An N layer 2 on a P type Si substrate 1 is isolated by P<+> layers while an N layer 4 extending from a P layer 3 and the surface part thereof to the N layer 2 is formed. Then, overall surface is covered with an SiO2 film 5 to form Al electrodes 8, 9 respectively on the layers 3, 4. Furthermore, a P<+> layer 10 is junctioned to the backside junction surface of the N layer 4. When the PN junction is inversebiased, the width of a depletion layer 10' at the junction part of N layer 4 is narrower than the width W of another deple tion layer 3'' in the P Layer 3. Even if the width W fluctuates, the width W'' does not fluctuate since the depletion part 10' is isolated from the oxide film 4 at the N layer 4. In such a constitution, the constant voltage value is decided by the breakdown voltage at the depletion layer part 10' in the P<+> layer 10 having no effect on the charge accumulated in the oxide film 5 enabling a constant voltage diode to be manufactured with high precision.

Abstract: PROBLEM TO BE SOLVED: To provide a method and an apparatus for on-line prelabel analysis to amino acids with superior operability and quantitative performance, whereby problems in conventional prelabel and postlabel methods are eliminated and amino acids can be automatically turned to fluorescent derivatives without being contaminated and with good reproducibility. SOLUTION: A sample containing amino acids including a protein-consisting amino acid is reacted with OPA (ortho-phtalaldehyde), turned to a fluorescent derivative, and separated by a separation column, so that the fluorescence is detected in a prelabel amino acid analysis method. In the method, an amino acid separation moving phase to which OPA is added beforehand is used. While the moving phase is supplied to the separation column at all times, the sample containing amino acids to be detected at any point of a passage system where the moving phase reaches the separation column is supplied into the moving phase, thereby turning the amino acids to fluorescent derivatives.
