Title: Mis semiconductor device
Inventor: YANOKURA EIJI
IPC: H01L29/78
Filed: 1996-05-24
Abstract: PROBLEM TO BE SOLVED: To protect a device against an instantaneous current by providing a protective circuit for detecting the instantaneous current flowing between the source and drain to thereby lower the gate potential enough to lower the instantaneous current. SOLUTION: When an instantaneous current flows between the drain 2b and source 2s of a MOSFET 2 in a device, a drain current flows a one- thousandth of the instantaneous current in a current detecting MOSFET 4 of a protective circuit 3. If the voltage induced by this drain current in an inductance 6 exceeds the threshold of a current cutting MOSFET 7, the MOSFET 7 turns on to flow a drain current, this lowering the gate voltage applied to a gate 2b of the MOSFET 2 connected to a gate resistance 5 by its voltage drop. As the result, the instantaneous current flowing between the drain 2d and source 2s of the MOSFET 2 in the device instantaneously reduces.

Abstract: PURPOSE:To permit a document input to be printed by any letter font by a method in which in case where the pattern of letter codes can be generated on the letter pattern of a given font, the letter pattern and foreign letter pattern are printed by a converter of font. CONSTITUTION:When a letter font for Japanese sentence is set up, letter code for one letter is read out from a document buffer, and when it is for foreign letter pattern, the code is converted into letter code for Japanese sentence and printed. In the case of foreign letter, a foreign letter pattern is read out and printed. In case where letter font for English sentence is set up, letter code for one letter is read out from the document buffer, and when it is for non-foreign letter and the printing is impossible on English printing mode, printing is made on the space. When the printing is impossible on English printing mode, the English letter is printed. When the letter code is for a foreign letter, the foreign letter is printed. Printing can thus be made by any letter font by optimal letter font in the case of mixed different letter fonts.

Title: Dynamic pressure bearing rotating device
Inventor: NAKASUGI MIKIO
IPC: F16C32/00
Filed: 1989-05-25
Abstract: PURPOSE:To prevent damage of a thrust bearing and keep the position of a rotor with high accuracy by arranging a rotor magnet and a stator in such a manner that in the static state, the axial force between both members is hardly applied, and during rotation, the electromagnetic force is applied in the opposite direction to the pressure of the thrust dynamic pressure bearing. CONSTITUTION:An iron core 12a of a stator 12 is disposed in a neutral position in the axial direction to a rotor magnet 10, so that while an electric current is not applied to the stator 12, the axial force is hardly applied and the force applied to a thrust bearing portion is only the dead load of a rotor including a polygon mirror 9 and so on. A coil portion 12b of the stator 12 is disposed in such a manner as to shift from the rotor magnet 10, so that when an electric current is applied to the stator 12, the electromagnetic force works, and the axial force opposite to the dynamic pressure generating direction of a thrust bearing is applied to the rotor magnet 10 and a rotary sleeve 6. Accordingly, the axial position of the rotor can be regulated by balancing of floating force made by the electromagnetic force, the dead load of the rotor and the dynamic pressure of the bearing. Thus, damage of the thrust bearing can be avoided, and the axial position of the rotor can be kept with high accuracy.

Abstract: PURPOSE:To attain YC separation with less deterioration in the resolution and less crosstalk by utilizing the correlation of pictures in the moving picture processing so as to apply YC separation to the picture in the moving adaptive type YC separation filter. CONSTITUTION:An in-frame YC separation circuit 50 detects correlation of pictures between fields when a moving detection circuit 80 discriminates a picture to be a moving picture and no vertical edge component is detected by a vertical edge detection circuit and any of the three kinds of in-frame YC separator circuits 50 including inter-field operation, horizontal and vertical in-field operation including band limit is selected depending on the quantity of the correlation. When a vertical edge component is detected, the correlation between fields is locally detected and three kinds of in-frame YC separator circuits 50 including inter-field operation, horizontal in-field operation with/ without band limit is selected depending on the result of detection. Thus, the in-frame YC separation Y signal and the in-frame YC separation C signal are outputted in this way. Thus, a picture with high resolution and less in picture quality deterioration due to crosstalk is reproduced.
