Abstract: PURPOSE:To measure the concn. of org. matter by simple procedures of measuring the quantity of the light emitted in the process in which the org. matter in the raw water of water works is oxidized by an oxidizing agent and computing the consumption of the oxidizing agent. CONSTITUTION:Sample water is injected by a prescribed volume from a sample water container 3 into a reaction ell 1. Further, a prescribed volume of potassium permanganate and acid or alkali soln. are injected into the cell 1. The liquid mixture is heated for a specified period of time by a thermostatic chamber 2 to cause an oxidation reaction. The quantity of the light generated at the time of the reaction is measured by a photoelectron multiplier (photo cell) 11. Computation is made by a computing element 12 in accordance with the count value outputted by the photo cell 11 and the quantity of the light emitted per specified volume of the sample for a specified period of time is determined. Further, the consumption of the potassium permanganate is determined from the quantity of the emitted light by the predetermined conversion equation. The quantity of the emitted light and the consumption of the potassium permanganate are displayed respectively on a display device 13 for the quantity of the emitted light and a display device 14 for the consumption of the potassium permanganate to end the measurement.

Title: Character recognizing method
Inventor: SHIMIZU HIROYUKI
IPC: G06K9/68
Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To improve a correct read rate by performing recognition by using a reference vector found from a predicted feature vector. SOLUTION: A recognition character selection block 14 selects the feature vector of an input character which is securely recognized out of the recognition results of respective characters stored in a character information storage block 13. A feature-vector-by-writer prediction block 15 predicts the feature vector of a category other than a recognized category decided to include an input character selected by using the feature vector and using a recursive expression. A reference-vector-by-writer correction block 16 finds a reference vector dedicated to a writer from a reference vector for an unspecified writer by using the feature vectors of individual categories predicted from the feature vector. Further, a character recognition block 17 finds the value of a distance or similarity to the feature vector of each input character by using a new reference vector and performs rerecognition.

Title: Camera
Inventor: ARITA HIROSHI
IPC: G03B17/38
Filed: 1991-02-13
Abstract: PURPOSE:To improve operability in one-point range-finding mode photographing by means of remote control release by maintaining the one-point range-finding mode until a releasing signal is outputted from the releasing means of the camera main body. CONSTITUTION:A remote control releasing flag is provided in a sequence controller 1. A flag goes to '1' when release by use of a remote controller is performed, and it goes to '0' when release by use of a releasing switch 14 is performed. Before the return to the initial condition, the flag is checked. When the flag indicates '0', the multipoint range-finding mode is automatically set irrespective of the range-finding mode; when the flag indicates 1, the range- finding mode is left as it is. That is, in the releasing operation by the remote controller, autofocusing by one-point range-finding is performed unless release by the release-switch 14 of the camera main body is selected.
