Title: Thermal louver
Inventor: KOMATSU TAKAHIRO
IPC: B64G1/50
Filed: 1989-09-30
Abstract: PURPOSE:To effectively control suitable temperature with a compact construction by concentrically providing a thermal shield plate inside a substrate whose radiation coefficients of infrared ray are respectively specified and which respectively consist of cylindrical members having holes opened and by relatively moving them in accordance with change in temperature. CONSTITUTION:A thermal louver for protecting an artificial satellite or the like comprises a cylindrical substrate 1 having holes 10 opened on an outer peripheral wall, a cylindrical thermal shield plate 2 accommodated therein and having holes 20 opened which correspond to the holes 10 and a driving portion 3 having a bimetal 3c for relatively moving them in accordance with change in temperature. When temperature in the artificial satellite rises near to an upper limit value, the bimetal 3c is expanded to rotate a pinion 3b. A rack 2b is moved to close the holes 10 of the substrate 1 by an outer surface 2a of the thermal shield plate 2. Thus, heat in the satellite is moved to an inner side face 1a of the substrate 1 through the holes 20 to lower the temperature to a proper value.

Title: Insulated-gate field-effect transistor
Inventor: KAYAMA CHIZURU
IPC: H01L29/78
Filed: 1988-10-11
Abstract: PURPOSE:To decrease a gate capacitance by a method wherein an impurity layer whose conductivity type is opposite to that of a gate electrode is formed at the center of the gate electrode section and made floating. CONSTITUTION:An impurity layer whose conductivity type is opposite to that of a gate electrode 6 is formed on the center of a gate polysilicon section of the gate electrode 6 and made to float potentially. That is, when a transistor is ON, a depletion layer 17 is made to expand as an impurity layer 7 is in a floating condition and to shrink in operating area. By this setup, a capacitance is decreased and the concentration of an electric field under the gate electrode 6 is moderated, so that a transistor of this design can be prevented from deteriorating in breakdown strength. And, even if this constitution is applied to an n-channel type field effect transistor or a p-channel type field effect transistor, the same effect as above can be obtained.

Title: Forming method for filling water-resistant film of glass ionomer type
Inventor: ONOSE HIDEO
IPC: C09D5/00
Filed: 1988-10-14
Abstract: PURPOSE:To prevent water sensitiveness of glass ionomer type filling and protect its surface form and aesthetic property by using an aid member consisting of a matrix outer layer, which suits the sinus shape to be filled, and a film as an inner layer situated at the inner surface of the matrix. CONSTITUTION:A film as inner layer adapting to the sinus shape to be filled is arranged at the inner surface of the outer layer of matrix, and after the sinus is filled with glass ionomer type material, the matrix with built-in film is put over the filling part, and the outer layer of matrix is removed following hardening of the glass ionomer type material. Thereby only the film is attached to the glass ionomer type material, which can thus be protected against moisture. Covering the surface with a clear skin makes it easy to check the fit condition of the perimeter of the sinus. Removal of the film after 24hrs or after necessary time for anti-moistening according to necessity will achieve an excellent glass ionomer type touched-up surface which is free from influence of the moisture in the oral cavity.

IPC: G06T7/60
Filed: 1994-09-28
Abstract: PURPOSE: To perform a high-speed matching with image data of a body to be processed which is picked up at various tilt angles by using a small number of model images. CONSTITUTION: Picked-up image data from a TV camera are registered in an image memory 8 and a tilt detection part 9a finds the tilt angle of the object. In a RAM 12, a model image having a 0 deg. tilt angle is registered. A recognition part 9b makes a serial search for the image data to make a rough search for detecting the presence position of the object in the image data and then makes a random search for the image data on the basis of the detected presence position data of the object, and makes the data match with the model image. A memory control part 7 when reading the image data out of the image memory perform affine transformation on the basis of the detected tilt to rotate the picked-up image data by a specific angle so that the data match with the angle of the model image, and outputs and sends the result to a recognition part 9b.

Title: Fastening screw
Inventor: NAKAMURA DAIJIRO
IPC: F16B37/00
Filed: 1992-08-31
Abstract: PURPOSE:To prevent over-tightening of a screw member beyond a set value and make its removal easy by providing a torque transmitting member between a screw member and an operating ring, and also providing an one-side torque limitter which cuts off the torque transmission in the case of a specified load. CONSTITUTION:In order to attach a rotary tool 20 to a drive shaft 17, a flange ring 15 side of a fastening screw 10 is faced to a tool 20 side, and a screw member 13 of the screw 10 is faced to a tool 20 side, and a screw member 13 of the screw 10 is fitted to a mounting bolt 18, and then an operating ring 11 is turned by hands for screw fitting. If the ring 15 does not touch the tool 20 during screwing, the screw 10 rotates integrally. When the ring 15 abuts on the tool 20, only a revolution of a revolving ring 12 is allowed because its rotation is prevented by the engagement with the flange ring 15, and the tool 20 can be fastened by large fastening force because of the difference between the number of the teeth of the external gear of the revolving ring 12 and the internal gear of the screw member 13. When the fastening force reaches the set value, a sliding member 14 rotates freely, and the transmission of the torque is interrupted. In the case of loosening the fastening screw 10, the turning of the operating ring 11 in the loosening direction makes the revolving ring 12 move into a revolving motion and the fastening can be loosened.
