Title: Line width recognizing device
Inventor: BAN KYOKO
IPC: G06K9/46
Filed: 1985-02-25
Abstract: PURPOSE:To shorten the processing time without reducing a recognition ratio by constituting a line width recognizing device with an original picture memory part, a reduced picture memory part, a reduced picture line width recognizing part, an original picture line width recognizing part and a final line width recognizing part. CONSTITUTION:The reduced picture memory part 2 stores the ORed m-number of original picture elements (longitudinal direction) X m-number of picture elements (lateral direction) from picture elements on the picture of the original picture memory part 1 where binary picture information inputted through a facsimile, scanner, etc., is stored. Based on the picture elements on the reduced picture, a line segment processing part 3 extracts start and the end points of the line segment and the intersection point of horizontal and vertical lines as a node. With the use of the reduced picture, the reduced picture line width recognizing part 4 obtains the line width between respective nodes, and inputs it to a line width information part 7. In terms of the part whose line width cannot be obtained from the reduced picture, the line width is recognized 5 from its original picture, and inputted to the memory part 7. In terms of the part still non-decided, the distance between nodes before and after the part concerned is noticed, and stored 7 as a thick line only when it is thick. Thus the line width is efficiently recognized.

Title: Image pickup device
Inventor: KOJIMA MOTOHIRO
IPC: G02F1/13
Filed: 1986-02-20
Abstract: PURPOSE:To obtain an image pickup device having always a good image pickup characteristic regardless of the intensity of incident light, by controlling the intensity of light made incident on a photoelectric transducer using a layer possible to change electrically the transmission factor of the light. CONSTITUTION:The light is made incident on a solid-state image pickup element 7 through a lens 1 and a liquid crystal panel 6. The solid-state image pickup element 7 is driven by a driving circuit, and an output from the solid-state image pickup element 7 becomes a video signal output with a signal processing circuit 5. The signal processing circuit 5 also outputs a voltage corresponding to the average output of the solid-state image pickup element 7, and it is impressed between electrodes in the liquid crystal panel 8. The liquid crystal panel 6 has an impression voltage dependency with the transmission factor shown in figure. When the voltage corresponding to the average output of the solid-state image pickup element 7 is impressed on the liquid crystal panel 6 from the signal processing circuit 5, the transmission factor of the liquid crystal panel 6 is varied according to the characteristic shown in figure. When strong light is made incident on the solid-state image pickup element 7, the average output is increased, therefore, the voltage impressed on the liquid crystal panel 6 is increased, and the transmission factor is decreased, thereby, a force to weaken the intensity of the light made incident on the solid-state image pickup element 7 is functioned.

Title: Multicolor transfer type thermal recorder
Inventor: TAKAHASHI YOSHIHIKO
IPC: B41J11/00
Filed: 1984-02-28
Abstract: PURPOSE:To enable the coinciding of the recording start position with a recording paper at a plurality of recording sections by temporarily stopping the conveyance of the paper at the recording sections at the subsequent stage when the conveyance of the recording paper reaches a certain value beyond that corresponding to mutual recording position intervals. CONSTITUTION:A microprocessor 39 temporarily stops a stepping motor 18B when the number of lines recorded at the first recording section reaches a value T corresponding to the conveyance of a recording paper from the recording position of the first recording section to that of the second recording section based on the output of a reading address counter 32A. At the same time, an AND gate 36B closed is opened to input a reading clock phi2. The reading of recording information memorized in a memory 30B begins to start the recording in a recording color. As a result, the recording start positions at the recording sections can be matched accurately to enable the fine adjustment of the conveying speeds between the recording sections independently thereby minimizing the color deviation as a whole.

Title: Semiconductor device and its manufacture
Inventor: HIMI KEIMEI
IPC: H01L29/786
Filed: 1994-02-08
Abstract: PURPOSE:To obtain an electrode structure which does not require any aligning margin and has an aligning property by forming a first electrode of a metal having low transmissivity against X rays so that the electrode can have a self-aligning relation with other electrodes. CONSTITUTION:An X-ray resist 10 is irradiated with X rays from an Si substrate 100 side. The X rays are transmitted through the substrate 100 in areas where no X-ray absorbing material nor W electrode 5 which becomes a reflecting material exist and arrive at the resist 10. As a result, the resist 10 is exposed to the X rays and forms an exposed areas 10b. Since the area with the electrode 5 does not transmit the X rays, the resist 10 on the electrode 5 is not exposed. Since the polymer chain of the resist is cut and the resist becomes soluble in a developing solution in the exposed areas 10b, whereas the unexposed area 10a remains insoluble, when a positive resist is used as the resist 10, the resist 10 can be patterned in a self-aligning way with back gate electrodes 5 and 4. Therefore, the need of an aligning margin can be eliminated.

Abstract: PURPOSE:To prevent a generation of a short accident caused by a melting of an electric source cord by setting a current suppression means suppressing a current flowing in the electric source cord through discrimination of the electric source cord temperature rising to an abnormal range of temperature. CONSTITUTION:By using a temperature sensor 12 mounted on a cord reel, a temperature of an electric cord 9 is detected by a second temperature detecting circuit 23, and whether the detected temperature exceeds a temperature that is set by a temperature standard circuit 24 or not is discriminated by a second comparison device 25. If a temperature of the electric cord 9 rises abnormally and exceeds the set temperature, an output of the second comparison device 25 becomes L from H, and the electric cord has a decreased electric current quantity which flows in itself and a self heat generation is suppressed. Thereby, the short accident caused by melting of an outside skin of the electric source cord can be prevented.

Title: Acoustic reproduction device
Inventor: NAKAMURA YOSHIO
IPC: B60R11/02
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To extend a reproduction band while reducing a load noise by providing a control means that varies a feedback coefficient in a feedback system in response to a magnitude of a reproduction signal from a signal source to the acoustic reproduction device. SOLUTION: A microphone 15 picks up a reproduction sound component from a speaker 14 and an external noise component around the speaker, its output signal is given to a subtractor 12 via a phase correction circuit 16 and a variable amplifier 17 and an output of the subtractor 12 is negatively fed back to a reproduction signal. The reproduction signal at an input terminal 11 is fed to the variable amplifier 17 as a control signal so as to vary a feedback coefficient of a feedback variable from the microphone 15 to the subtractor 12 depending on the magnitude of the reproduction signal.  Thus, in the case that the magnitude of a music signal is small, the amplifier 17 is controlled so that the reproduction frequency band of the music signal is made narrow and instead the noise suppression effect is maximized, and in the case that as the magnitude of a music signal is larger, the amplifier 17 is controlled so that the reproduction frequency band of the music signal is made wider and instead the noise suppression effect is being decreased.
