Title: Insulated gate type field effect semiconductor device
Inventor: YOU KANJI
IPC: G05F3/24
Filed: 1984-11-28
Abstract: PURPOSE:To obtain the constant voltage of high accuracy by deciding the threshold voltage of a MISFET with a gate electrode containing no impurity. CONSTITUTION:Equations I and II show the threshold voltage of a MISFET having a gate electrode which contains n and p type impurities. While an equation IIIshows the threshold voltage with the gate electrode including no impurity. An equation IV is satisfied among these threshold values. The MISFETs Q1 and Q2 contain a pinip and pipip type gate electrodes respectively and connected in series. The threshold values of the FETs Q1 and Q2 are shown by equations Vand VI from the equation IV. Then the difference is obtained between the threshold values of FETs Q1 and Q2 to obtain the voltage corresponding to a silicon energy gap, i.e., the difference of the work function among an n<+> gate electrode of the FETQ1, an (i) electrode of the FETQ2 and each substrate. This energy gap has an extremely small level of dependence on the production conditions and the ambient temperature conditions. Thus the constant voltage can be obtained with high accuracy.

Title: Rear wheel steering device
Inventor: YOSHIDA YASUHIKO
IPC: B62D5/26
Filed: 1985-11-08
Abstract: PURPOSE:To steer the rear wheels in the same and opposite phases as/to the front wheels steering angle by furnishing a direction control valve to switch over a hydraulic circuit in interlocking with a front wheels steering device, operating a hydraulic actuator with oil pressure which is transmitted via said control valve, and thereby performing steering of the rear wheels. CONSTITUTION:When a steering wheel 24 is turned counterclockwise to swing the head of car to the left, an oil line is switched over by a control valve 27, and a piston 29 of a power cylinder 26 moves to right to steer the front wheels 21 leftwise. At the same time, a spool 37 of a hydraulic selector valve 33 is moved to right according to the pressure difference between the left and right chambers 30a, 30b of said power cylinder 26. Here a smaller steering angle of front wheels corresponds to smaller amount of spool motion, and at this time, a control valve body 45 of a direction control valve 43 moves to right for a smaller distance, whereabout larger corresponds to larger. Thus the flow path in a hydraulic circuit 58 is switched over. Thereby a piston 72 of a hydraulic actuator 63 for steering the rear wheels is moved to the left/right, and the rear wheels 22 are steered in the same phase as/opposite phase to the front wheels 21.

Title: Luminous radiation electron tube
Inventor: TOUHOU MAKOTO
IPC: H01J63/08
Filed: 1983-12-23
Abstract: PURPOSE:To enable a luminous radiation electron tube to be attached directly to the flat surface of a ceiling or the like by installing an anode concentrically with a semicylindrical outer tube. CONSTITUTION:In a semicylindrical outer tube 21, a thermion-radiating bar-like cathode 22 is installed in such a manner as to be located almost in the center of the arc of the semicircular cross section of the outer tube 21. Besides a semicylindrical wire mesh anode 23 is installed in such a manner as to concentrically surround the cathode 22. Owing to the above constitution, a majority of the ultraviolet rays produced through excitation becomes incident upon a phosphor 25 existing on the round inner surface of the semicylindrical outer tube 21. The remaining part of the ultraviolet rays is scattered toward the flat inner surface of the tube 21 before being reflected by a reflecting film 26, and finally become incident upon the phosphor 25. Therefore it is possible to attach the luminous radiation electron tube to a flat surface.

Title: Picture processor and picture processing method
Inventor: ISHIDA YOSHIHIRO
IPC: G06T9/20
Filed: 1994-10-17
Abstract: PURPOSE: To faithfully variable-magnify a picture expressed with outline vector into an original picture even at the time of reducing the picture. CONSTITUTION: The outline vector is extracted by an outline extraction means 12 from a binary picture acquired by a binary picture acquirement means 11. An outline smooth variable-magnification means 13 smoothes the picture expressed by the outline vector and variable-magnifies it. A variable magnification rate in this case is controlled by a variable magnification control means 17 so that the variable magnification rate of a second variable magnification means 16 and a synthesized variable magnification rate become desired ones. The smoothed and variable-magnified picture data is converted into the binary picture by a binary picture reproduction means 14. The binary picture is variable-magnified by the second variable-magnification means 16. It is desirable that the variable magnification rate of the smooth variable magnification means 13 becomes more than one.  Thus, the variable magnification of picture data expressed by vector is limited to enlargement. Abuses that faithfulness to the original picture is lost or unnecessary data is required to be processed at the time of reduction, can be prevented.

Abstract: PURPOSE:To smoothen the web opening operation by providing possibility of changing over an entanglement preventive member installed on an upper and a lower guide roll into the entanglement preventive attitude unambiguously associate with changing-over of the moving direction of a traveling body. CONSTITUTION:A wind pressure is applied to the part 14a of a web stretching upward upon being drawn out from a placing table 13 to between an upper and a lower guide roll 15, 16, and this web part 14a should assume swelling backward. In the back part is situated a lower entanglement preventive member 22 which is consolidated with the lower guide roll 16, so that the swell of the web part 14a will remain in such a degree as lightly touching the undersurface of the lower entanglement preventive member 22. Therefore, there is no risk of hindrance in paying out the web 14, and the wind pressure will stream backward from the left and right sides of the web 14, which should prevent the swollen part of web from entangling between the group 17 of intermediate rolls from the above side.

Title: Automatic equalizer
Inventor: MUROMOTO ATSUSHI
IPC: H04B3/06
Filed: 1990-09-21
Abstract: PURPOSE:To remove the equivalent remaining component of a front equalizer by providing a switching circuit which turns on or off an adaptive matching filter in correspondence with a case when an advance echo is included in an input signal and a case when a lag echo is included. CONSTITUTION:When a line shown by two-wave model includes the advance echo, there is no voltage in correlators 14+4-14+1. The voltage is generated in the tap of one or plural correlators 140-14-N. A tap weight detector 15 detects the presence or absence of a correlation voltage at every tap. When the result satisfies the condition of the advance echo, all the switches 13+N-130-13-N are turned on, the adaptive matching filter 1 is connected and an original operation is executed. When no echo is present on the line or only the lag echo is present thereon, there is no generation of voltage in the correlators 14-1-14-N and the voltage is generated in one or plural correlators 14+N-140. Thus, such a state is logically judged and only the switch 130 is turned on, whereby all the other switches are turned off.
