Filed: 1995-03-10
Abstract: PURPOSE: To easily and accurately design an analog integrated circuit by designing a layout by using a cell pattern which has the periphery of an element encircled with a ground power line (GND) and whose characteristics are already known. CONSTITUTION: The circuit is designed by performing circuit simulation using an ideal element, i.e., an element including no parasitic capacity. When desired performance (characteristics) is obtained, the ideal element is replaced with a cell equivalent circuit which has the same characteristic values and includes a parasitic component and the whole circuit is simulated. When the desired performance is obtained, the cell of the element used for the designed circuit is called from a library and the whole is arranged on a layout surface. This called cell consists of the element and GND at its circumference. Called cells 41-49 are arranged so that the same connections with the circuit can be made. Further, a gap (notch) between GND areas generated depending upon the large/ small relation among the cells is processed by adding a GND pattern, etc.

IPC: G11B5/127
Filed: 1990-03-05
Abstract: PURPOSE:To attain saturation recording with a small recording current in a perpendicular single layer magnetic recording medium by using a magnetic substance as a pad material. CONSTITUTION:A magnetic substance with a high permeability is used for a pad 1 opposite to a ring magnetic head 4 in a magnetic recording and reproducing device comprising the pad 1, a mmgnetic recording medium drive motor 3 and a ring magnetic head 4.

Filed: 1991-03-18
Abstract: PURPOSE:To reduce the diffusion and scattering of carriers by lowering the impurity concentration of a channel in a carrier conductive region and the intensity of the vertical electric field in the carrier conductive region and widening the width of the carrier conductive region. CONSTITUTION:A region 3 is an n<-> region and the impurity concentration of the region 3 is set at <1X10<17>cm<-3> so as to prevent a decline in the mobility of carriers caused by Coulomb scattering. It is important to allow the carrier 20 to run in this region 3 apart from the boundary between a gate film 22 and semiconductor. In addition, the electric field of the running region of the carriers 20 against the surface of the gate must be moderate and the impurity density in the running region of the carriers 20 must be low. Since a normal-off type MOS transistor is easy to use, the thickness and concentration of the n<-> region of the region 3 are important.

Abstract: PURPOSE:To detect a leak of a body to be tested, by a leak detector, by a method wherein the body to be tested which is filled up with compressed air and a trace gas is immersed in a liquid of a testing vessel wherein the liquid is held, and the inside of the testing vessel is exhausted to have a negative pressure. CONSTITUTION:An opening of a testing vessel 1 wherein a liquid 2 is held is closed airtightly by a cover 3. A body 5 to be tested is filled up with compressed air and a trace gas 4 and immersed in the liquid 2. The inside of the vessel 1 closed hermetically by the cover 3 is exhausted by driving a pump 8 for exhaustion. When there is any leak from the body 5 to be tested, the trace gas 4 leaks out with air bubbles 6, and it is detected by a leak detector 7. The generation of the air bubbles and the frequency thereof are increased by setting the inside of the vessel 1 to have a negative pressure. Since the trace gas is detected by the leak detector 7, it is unnecessary to observe the air bubbles by the eye, the leak can be detected highly precisely and reliably, and a time of inspection can be shortened.
