Patent JP-H04363028-A (JP)
Title: Semiconductor device and its manufacture
Inventor: EGUCHI KOJI
IPC: H01L21/20
Filed: 1991-09-11
Abstract: PURPOSE:To reduce an electric field to be concentrated in the upper-part corner part of a semiconductor layer by a method wherein an included angle between a base side and a lateral side in a lower-part trapezoid is formed to be larger than an included angle between a base side and a lateral side in an upper-part trapezoid. CONSTITUTION:N-type impurity regions 2a, 2b are formed down to a prescribed position from the surface toward the bottom face of an SOI film. By the n-type impurity regions 2a, 2b, a channel region 2c is formed at the upper part of the SOI film 2 situated at the lower part of a gate electrode. The SOI film 2 is shaped in such a way that an interval in the direction along the gate electrode 4 becomes narrow from the bottom face toward the surface of the SOI film 2. It is provided with a two-stage inclination from the bottom face toward the surface of the SOI film 1. That is to say, the SOI film 2 is shaped in such a way that two trapezoids have been piled up. When the upper-part corner part of the SOI film 2 is formed to be an obtuse-angle shape, it is possible to effectively prevent a dielectric breakdown which is caused when an electric field is concentrated in the upper-part corner part.

Title: Electronic blackboard device
Inventor: YAMANAMI TSUGUNARI
IPC: G06F3/0488
Filed: 1987-09-14
Abstract: PURPOSE:To improve operability by transmitting successively and intermittently a radio wave corresponding to each tuned frequency, from an antenna coil installed along the circumference of the writing surface of a blackboard main body, and receiving the radio wave reflected from a tuning circuit by the antenna coil, and detecting its frequency, and discriminating whether it is a marker or an eraser. CONSTITUTION:When the marker on the writing surface of the blackboard main body is operated, the radio wave with one frequency among the radio waves transmitted from the antenna coil 13 is received by the tuning circuits of the markers 2-4, and an induced voltage is generated. Even if the transmission of the radio wave from this induction loop coil is stopped, the induced voltage of the nearly equal frequency is generated in the antenna coil 13 having stopped suddenly transmitting a damped wave. Similarly, when the eraser 5 is operated, the induced voltage of the frequency nearly equal to other frequency is generated in the antenna coil 13 having stopped transmitting the radio wave. Thus, it can be discriminated which is being used on the writing surface the markers 2-4 or the eraser 5, according to the frequency of the induced voltage generated in the loop coil 14 having stopped transmitting the radio wave.

Title: Pressure detector
Inventor: MAJIMA NOBORU
IPC: G01L19/06
Filed: 1982-12-30
Abstract: PURPOSE:To attain simultaneously a small size, high performance and high reliability by forming a small magnetic space between a measuring chamber and a pressure receiving port, and packing a magnetic fluid therein thereby performing sealing. CONSTITUTION:A protective liquid such as silicone oil is packed in a measuring chamber 35, and a magnetic fluid is filled in the magnetic space 42 in a pressure receiving body 32 so as to cover the protective liquid while receiving a magnetic attraction force. When a measuring pressure P is exerted on a pressure receiving port 41, the pressure is transmitted via the magnetic fluid in the space 42 and the protective liquid in the chamber 35 to a pressure sensitive element 39 by Pascal's law. The pressure is converted to a change signal of a resistance value by a strain gage formed diffusively thereon and is outputted via leads 40 and 38 to the outside. The magnetic fluid is filled and held in the space 42 by magnetic force to form a magnetic fluid layer and therefore the outflow of the protective fluid in the chamber 35 is prohibited and the element 39 is protected for a long period of time without exposure to the outdoor air.

Abstract: PURPOSE:To prevent the improper transplantation of a seedling by surely controlling the rolling of a transplanter. CONSTITUTION:A transplanter 10 is attached to a mobile machine body in a rollable state. The rolling control (control of the lateral inclination) of the transplanter 10 is carried out by extending or contracting an actuator 26 with a controller 50 according to the difference of heights from the field face detected by the right and left field-face detection sensors 31R and 31L of the transplanter 10. When the detecting heights of both sensors 31R, 31L exceed a prescribed range by lifting the transplanter 10 in the case of turning the mobile machine body 5, etc., the rolling control is stopped. The control is restarted when the detected height is returned within the prescribed range. The trouble of control delay liable to occur in the lowering of a conventional transplanter 10 immediately after the end of turning motion caused by the rolling control in the turning motion can be eliminated and the posture of the transplanter 10 can be corrected without delay by the use of the apparatus.

IPC: G01R33/42
Filed: 1988-09-16
Abstract: PURPOSE:To reduce the magnetic flux reaching pole pieces and generate the inclined magnetic field output with no distortion by inserting slitless copper plates between permanent magnets, inclined magnetic field coils and slit copper plates. CONSTITUTION:Slitless copper plates 5 are provided on side faces of pole pieces 3 near permanent magnets, and four-slit copper plates 6 are provided at optional positions between inclined magnetic field coils 4 and slitless copper plates 5, e.g., on inclined magnetic field coils 4 in consideration of the easiness of assembling. There is no magnetic effect if the slitless copper plates 5 and the slit copper plates 6 are in contact, thus they are separated by a distance h=20-30mm, for example. Most of the magnetic flux generated by the inclined magnetic field coils 4 is absorbed by the slit copper plates 6 provided on the inclined magnetic field coils 4, the magnetic flux having passed slits is absorbed by the slitless copper plates 5 provided on the side faces of the pole pieces 3, thus very little magnetic flux reaches the pole pieces 3.
