Title: Recognition type document filing device and control method thereof
Inventor: HISAGAI MASAMI
IPC: G06K9/62
Filed: 1994-11-17
Abstract: PURPOSE: To perform accurate identification calculation later by preserving a feature vector for a character whose recognized result is doubtful. CONSTITUTION: Document images read by an image scanner 3 are stored in a RAM 4, the characters are segmented and the feature vectors are extracted. For the extracted feature vectors, an Euclidean distance with an average feature vector is calculated, the prescribed pieces of candidate character groups are obtained in an ascending order and they are stored in a large classification part 11. Thereafter, the respective candidates, pseudo Bayesian identification formulas for respective formats are computed and the upper prescribed pieces of the candidates are outputted. Then, a difference between the value of the pseudo Bayes identification formula of a first candidate among them and the value of a second candidate is decided, it is decided that the first candidate is correct when it is more than a fixed value and it is decided that the first candidate is uncertain when it is not.  For the character judged as uncertain, the feature vector relating to the character is stored.

Title: Address conversion system
Inventor: INAGAMI YASUHIRO
IPC: G06F12/10
Filed: 1987-11-11
Abstract: PURPOSE:To improve the management efficiency of a main memory by using plural address conversion tables and selecting an optimum address conversion size based on the program characteristics. CONSTITUTION:The bit decided by each address conversion size is selected out of a logical address 1 specified by a program. A means which shows whether each address conversion size is valid or not is provided within the entries of address conversion tables 5-7. Then the entries of tables 5-7 are specified as the specified information. The display means can be changed by the program. A CTOR 8 which manages a main memory sets the contents of storage at one of tables 5-7. Then the CTOR 8 registers the correspondence between a logical address 1 and real addresses 2-4 according to the working state of the main memory and at the same time sets said display means. As a result, the contents of the main memory are selected based on the program characteristics and can be also changed. Thus a main memory having the high control efficiency is obtained.

Filed: 1997-10-16
Abstract: PROBLEM TO BE SOLVED: To provide a method for adjusting the point of origin for a component transferring device by which the adjustment of the point of origin can be easily and accurately carried out. SOLUTION: First, a moving member 7 is positioned at the point of origin of the device with the aid of a point of origin adjusting tool (not shown) and the position detecting sensor 13 is brought to a state of outputting 'on' output signals.

Title: Gas rate sensor
Inventor: SAKAMOTO OSAMU
IPC: G01C19/00
Filed: 1987-11-12
Abstract: PURPOSE:To shorten characteristic stability time after the closing of a power source, by arranging posts made up of an insulation base section and a conducting film formed on the surface thereof to lower an absolute value of a temperature rise at the posts. CONSTITUTION:Hot wires 4f and 4g cause a change in a gas rate from the unevenness of a gas and as a change in the gas rate is proportional to an angular velocity, the change is detected as temperature difference between the hot wires 4f and 4g. Since insulation base sections 4b'-4e' composing the posts 4b-4e are made up of ceramics, resin and the like, heat transmitted from the hot wires 4f and 4g is transmitted to a conducting film 4l in which a heat conductivity is higher than the base sections 4b'-4e'. In this case, viewed from a total surface area/total capacity of the film 4l, as the film 4l is large, a temperature rise is limited with a better radiation characteristics. This allows a shorter time in the stabilization of a rising characteristic when a power source is closed to obtain a stable operation.

Title: Surface cleaning system for semiconductor element
Inventor: OGURI ISAO
IPC: B08B5/00
Filed: 1988-11-10
Abstract: PURPOSE:To effectively remove refuse such as dusts, etc., adhered to the surface of a semiconductor element in a short time treatment by oppositely disposing a hot blast diffusing nozzle on a conveying line of the element, and diffusing hot blast air managed at its temperature to a predetermined value through the nozzle to the surface of the element. CONSTITUTION:When air intaken from the environment is fed to a nozzle 4 by a blower 8 in the conducting state of an electric heater 5, the air is altered to hot blast, which is diffused down from the nozzle 4. The set value of the hot blast temperature is previously set to 200-250 deg.C, the value of a temperature sensor 6 is applied to a controller 9 to control to conduct the heater 5. When the element 1 is conveyed along a conveying line 2 in a state that the hot blast air managed at its temperature is diffused through the nozzle 4, the hot blast is diffused to the resin surface of the element 1. Thus, most of refuse such as dusts, etc., adhered to the surface of the element 1 is blown out by the air pressure of the host blast, the remainder is incinerated at that place in contact with the hot blast. The ash of cinders is blown out by the air pressure to be removed from the surface of the element 1.
