Filed: 1987-11-13
Abstract: PURPOSE:To obtain excellent adhesion with a conductor layer and excellent insulating property at low costs, by manufacturing insulating layers having a double-layer structure by using the same insulating paste, and manufacturing the insulating layers having a substantially three-layer structure. CONSTITUTION:Insulating paste includes alumina powder, glass ceramics powder and an organic binder and has a viscosity of 500kcps. The insulating paste is applied on a conductor layer of a ceramic wiring board. With the applied surface facing upward, the device is baked at a temperature increasing speed of 100 deg.C/min or less. The glass ceramics component remains at the upper part, and the alumina component remains at the lower part. When the temperature reaches the crystallizing temperature of the glass ceramics component, the constant temperature is kept. The baking is performed until the position of each particle in the powder does not move. Thus, a first insulating layer 3 is manufactured. The same paste for baking the first insulating layer is applied on the ceramic wiring board 1. The device is turned inside out so that the applied surface faces downward. Baking is performed in the same baking profile as in the manufacturing of the first insulating layer. Thus, a second insulating layer 4 is manufactured. The first and second insulating layers 3 and 4 are sequentially laminated, and a double-layer structure is obtained.

Title: Motor speed control method
Inventor: TANISAKA AKIHIKO
IPC: H02P29/00
Filed: 1992-09-30
Abstract: PURPOSE:To enhance response in speed control by applying an Hinfinity control theory to a speed control system for motor and arriving at a mixed sensitivity problem and then selecting frequency weighting functions to be multiplied by sensitivity function and complementary sensitivity function such that an Hinfinity  norm is decreased thereby determining a transfer function of controller. CONSTITUTION:A frequency weighting function W1 is set high under low frequency region because it is multiplied by a sensitivity function S which is required to be decreased especially under control band, i.e., low frequency region. A frequency weighting function W2 is set high under high frequency region becuase it is multiplied by a complementary sensitivity function T which is required to be decreased for high frequency components of mechanical system or fluctuation of plant, i.e., under high frequency region. When the frequency weighting functions W1, W2 are determined from such viewpoint and a transfer function K of controller is determined to satisfy the formula, an Hinfinity  control theory can be applied to a speed control system of DC motor and can arrive at conclusion of a mixed sensitivity problem.
