Title: Character recognizing device
Inventor: SUZUKI KAORU
IPC: G06K9/20
Filed: 1988-10-27
Abstract: PURPOSE:To obtain a character recognizing device where the inclination of a character row is detected with a high precision and its processing cost can be reduced by providing a reference line extracting means which extracts a prescribed reference line and defines the inclination of this reference line as that of the character row. CONSTITUTION:A reference line extracting part 4 or the like is provided to constitute a character recognizing device. This extracting part 4 imagines arbitrary lines passing a specific position of each character segmented by a character segmenting part 3 and obtains a histogram on a parameter space with respect to pairs of parameters prescribing these lines and extracts the line, which is prescribed by the pair of parameters which give the highest frequency of the histogram, as the reference line and outputs inclination information having the inclination of the reference line as that of the character row. Therefore, the inclination of the character row is calculated with a relatively small amount of picture data, and the processing cost is reduced. Further, the inclination of the character row is obtained with a high precision because the histogram is taken on the parameter space and the inclination of the reference line is determined by the pair of parameters of the point of highest frequency.

Title: Anechoic chamber for radio wave
Inventor: KAIBUCHI SUMIO
IPC: G01R29/10
Filed: 1987-10-28
Abstract: PURPOSE:To prevent a primary reflected wave from returning to a receiving antenna by a method wherein a housing space is composed of walls made of metallic material and at least one wall is inclined against the received polarization reference line. CONSTITUTION:A housing space 17 is composed of a floor wall 11, a ceiling wall, a front wall 12, a rear wall 13, a left wall 14 and a right wall 15 made of metallic material. A transmission source 21 and a receiving antenna 22 are provided in the space 17 so as to be vertical to the floor wall 11. In this case, if all the side walls 12-15 are vertical, the direct vertical polarization from the transmission source 21 and the vertical polarization of the primary reflection produced by the side walls 12-15 are received by the antenna 22. If one of the side walls 12-15 is inclined, the magnitude of the wave received by the antenna 22 is varied and the primary reflected wave can be so controlled as not to return to the antenna 22. When the horizontal polarization is measured, the ceiling wall is inclined. Thus, the reflected wave is not received by the antenna 22 if the walls of the space 17 are properly inclined and, moreover, the space 17 is protected from external radio waves by the metallic walls. As a result, the measurement accuracy of the generated radio wave can be optimized.

Title: Digital telephone set
Inventor: KASHIWAGI KENICHI
IPC: H04M1/00
Filed: 1985-12-02
Abstract: PURPOSE:To simplify the connection work by providing a polarity correction circuit between a receiver and an interface circuit to eliminate the need for the confirmation of the polarity at the time of connection even when a line R is connected reversely. CONSTITUTION:A polarity correction circuit 5 is provided between the receiver 2 and the interface circuit 4. When the connection of the line R is correct in the polarity correction circuit 5, since a selector selects a CMI signal no inverted at all times, the CMI signal with correct polarity is fed to the interface circuit 4. On the other hand, when the connection of the line R is reversed, the CMI signal desired to be inverted is the correct CMI signal. The selector selects the CMI signal not inverted at first and when the output of a polarity inversion detection section comprising 8-stage of shift registers goes to logical '1', the selector selects the inverted CMI signal. Thus, the correct CMI signal is fed to the interface circuit 4.

IPC: H01L21/30
Filed: 1991-10-18
Abstract: PURPOSE:To open a fine pattern by decreasing a resist photosensor of the periphery of a pattern opening by a shielding film of an auxiliary pattern to locally suppress a swell and forming a fine unexposure part to decrease the residual thickness of the film. CONSTITUTION:A negative type resist film 2 provided with a shielding film 4A of an auxiliary pattern having a line width of less than a critical resolution size on the periphery of an opening of a shielding film 4 of a desired pattern is irradiated with an ultraviolet ray through a mask to be exposed. Then, when the resist film after the exposure is developed, a rectangular recess corresponding to the film 4A of the auxiliary pattern is not photosensed, and hence resist molecules are not bonded to a chain but removed by developer. The residual film amount of the opening is reduced that much, and hence a swelling amount is decreased. Thus, the residual thickness of the resist film which is easily affected by the influence of the swell is controlled to pattern a fine pattern with high resolution, and a device can be micronized.
