Title: Dictionary and character recognizing method
Inventor: KOJIMA KEIJI
IPC: G06K9/03
Filed: 1989-01-12
Abstract: PURPOSE:To cope with variance in character shape effectively by classifying and organizing each character by categories according to the shape feature of the character image and whether it is stable or unstable. CONSTITUTION:Areas 101 classified by the categories are secured in the memory space 100 of a dictionary memory (ROM or RAM), specific category numbers are assigned to the respective areas 101, and the dictionaries of characters classified by the category numbers are stored. Then, matching with a feature quantity extracted from the character image is carried out as to the dictionaries of stable and unstable categories corresponding to the shape features extracted from the character image and the dictionary of specific unstable categories (categories for character deformation) relating to the shape features. Consequently, a dictionary for character recognition wherein variance in character shape is considered is realized with relatively small amount.

IPC: G01R31/36
Filed: 1983-01-17
Abstract: PURPOSE:To detect the timing of discharge to be done in an accurate manner, by making full use of a fact that internal resistance grows large in a battery simultaneously with the discharge, while checking the terminal voltage at that time in a way of making a large current into a flow a moment. CONSTITUTION:In order to operate a device 35, when a key 34 is pressed, this device 35 is set in motion and simultaneously a pulse is outputted out of an input P of a central processing unit 33 whereby the first portion flows into a condenser 31 (a so-called rush current) as a collector current for a transistor 28 and then those from the second one downward flow into a resistor 30. While operating the device 35, if the quantity of discharge reaches a point 14 shown in this discharge characteristic drawing, internal resistance inside a battery 1 rises as the rush current flows so that output voltage of the battery 1 drops to some extent. So, finally no current flows into a Zener diode 16, stopping the conduction of transistors 17 and 21, and the S input of an RS flip-flop circuit 24 is turned to ''H''. With this rush current, when a Q output is turned to ''H'', the lighting of an LED25 goes out, informing an operator of the discharge start timing immediately.

IPC: G02B6/12
Filed: 1999-01-13
Abstract: PROBLEM TO BE SOLVED: To obtain roughly a set-up wavelength in a set-up temperature range, by reducing light transmission central wavelength temperature dependency of an array waveguide type diffraction grating or the like. SOLUTION: A plate member 8 having a larger coefficient of linear expansion than a substrate 1 is installed on the rear face side of the substrate 1 of an array waveguide type diffraction grating 11 for dividing the light having plural wavelengths from the light having respectively different plural wavelengths inputted from a light input waveguide 2 by a diffraction effect of an array waveguide 40, and for outputting the light from each light output waveguide 6. Light transmission characteristics of each output light have a light transmission characteristic for transmitting the light with mutually different light transmission central wavelengths as each center.  The light transmission central wavelength is shifted to the long wavelength side by a temperature rise, and the plate member 8 is expanded more largely than the substrate 1 by the temperature rise at that time, and the substrate 1 is warped projectingly to the lower side. Hereby, A compressive stress is added to the array waveguide 40 or the like, and the refractive index and the length of the array waveguide 40 are reduced, and each light transmission central wavelength is shifted to the short wavelength side, to thereby reduce a temperature dependency change of each light transmission central wavelength.

Title: Image forming method
Inventor: SUGITA TATSUYA
IPC: G03G17/06
Filed: 1995-01-20
Abstract: PURPOSE: To provide an image forming device which moves toner by irradiation of light and moves the toner by actuating larger force than light pressure on toner. CONSTITUTION: Light from a light source 20 is applied on toner held on a transparent belt 202 through a space modulator 50. Since toner absorbs light, generates heat, and receives optical migration force, it reaches paper 150 from the transparent belt 202, forming an image. Fog can be removed by a cleaner 220 by fixing toner by light from the light source 20. As optical migration force can act larger force than light pressure on toner, toner held by a holding body overcomes adhesion force and can move easily.
