Title: Magnetic head
Inventor: NAKAMURA TOMIO
IPC: G11B5/23
Filed: 1978-01-18
Abstract: PURPOSE:To enable a digitally recording and reproducing rotary magnetic head to effect the parallel processing of two tracks by interposing a common I-type core between special C-type cores having stepped portions formed with a gap and a winding space. CONSTITUTION:Ferrite blocks 11 and 11' and ceramic blocks 12 and 12' are jointed to form winding spaces 15 and 15'. Moreover, the blocks 11 and 11' are formed with the stepped portions such as grooves 14 and 14' for determining the shape of a gap and the width of the tracks. The resultant C-type cores 20 and 20' are bonded with glass through a common I-type core 13, and the grooves 14 and 14' are filled up with glass. Then, the side to face a magnetic tape is finished, and the winding is accomplished in the spaces 15 and 15'. Although four gaps 16, 16', 21 and 21' are formed of the grooves 14 and 14', only the gaps 16 and 16' are used for recording and reproducing purposes. Thus, the spacing between the gaps 21 and 21' and the magnetic tape is made sufficient as to exert no influence upon the recording and reproducing operations by the spherical finish of the surface.

Title: Composite cooker
Inventor: BETSUSOU DAISUKE
IPC: H05B11/00
Filed: 1989-01-10
Abstract: PURPOSE:To easily perform cooking such as boiling or singeing on food by inserting a microwave shielding plate provided with cut sections to prevent a closed loop between the heating coil of an induction heater and a container mounting plate. CONSTITUTION:The high-frequency magnetic field 10 is generated by a current 9 flowing in a heating coil 3. This high-frequency magnetic field 10 generates an eddy current on a container storing food such as a pot made of a conducting material and heats the container itself, and the food in the container is heated and cooked. When a shielding plate 1 made of a conducting material such as copper, aluminum or stainless steel to shield microwaves 7 is mounted on this coil 3, the high-frequency magnetic field 10 generated by the heating coil 3 tends to feed a current to this shielding plate 1. However, cut sections 2 are provided on the shielding plate 1, and the current 11 which the high-frequency magnetic field 10 tends to generate can not flow. The short-circuit current 11 by the high-frequency magnetic field 10 can be prevented by providing the out sections 2 on the shielding plate 1.

Title: Field effect transistor and its manufacture
Inventor: KUBOTA HIROSHI
IPC: H01L21/28
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To improve the reliability of a gate insulating film while voidance of a gate electrode prevented, by providing a gate electrode with a lower part region where only phosphorus is introduced as impurity and an upper part region where phosphorus and n-type semiconductor whose segregation coefficient is smaller than it are introduced as impurities. SOLUTION: An electrode 6 of a field effect type transistor comprises a lower part region 6a where only phosphorous is introduced as impurity and an upper part region 6b where phosphorus and arsenic are introduced as impurities. Only phosphorus wherein the impurity diffusion amount as impurity into a gate oxide film 3 is smaller than arsenic is introduced in the lower part region 6a contacting the gate oxide film 3 of the gate electrode 6, so the reliability of the gate oxide film 3 is high. This is because the segregation coefficient of arsenic at the interface between a silicon film 4 and the oxide film 3 is small. A shallow joint with arsenic is formed while the film thickness of electrode kept thick for finer construction, so presence of phosphorus prevents voidance of an electrode.

Title: Optical nonlinear element
Inventor: ANDO HIROAKI
IPC: G02F1/35
Filed: 1988-01-14
Abstract: PURPOSE:To eliminate the need for external electric circuits and to facilitate production and integration by providing a structure laminated with multiple periods of a 1st semiconductor layer, semiconductor multilayers, 4th semiconductor layer, and semiconductor multilayers as one period. CONSTITUTION:The main part of this optical nonlinear element is constituted of the laminated semiconductor layers consisting of the repetitions of the nipi structure in which the i layer is a multiple quantum well layer 3 and the n layer 2 and p layer 6 are of the semiconductor having the energy larger than the energy of the exciton absorption of the multiple quantum well layer 3. While this optical nonlinear element utilizes the electric field effect of the exciton absorption in the multiple quantum wells like with the conventional type, only the built-in potential difference of the pin type junction is utilized as the source of the electric field impressed to the multiple quantum well layers 3 and the direct effect of optical carriers such as electrons and holes generated when input light 12 is projected thereon is utilized for controlling the impressed electric field; therefore, the external electric circuit which is heretofore indispensable for the element of the conventional type is not needed. The need for the external electric circuits is thereby eliminated and the production and integration are facilitated.
