Title: Production of aluminum nitride sintered body
Inventor: SAKAIDA TOSHIAKI
IPC: C04B35/581
Filed: 1988-08-22
Abstract: PURPOSE:To enable production of an AlN sintered body with high density and high thermal conductivity using the normal pressure sintering method by using a specified alkaline earth metal salt of an acrylic acid-based copolymer as a sintering auxiliary. CONSTITUTION:An alkaline earth metal salt of a poly(meth)acrylic acid or (meth)acrylic acid-based copolymer is blended with powdery AlN in an amount of 0.2-2atomic% in conversion as the alkaline earth metal element. A molding of the resultant mixture is sintered in a non-oxidizing atmosphere under normal pressure to produce an AlN sintered body with a high density and high thermal conductivity. The effect of the above-mentioned sintering auxiliary is not shown and sufficient high values of the density and the thermal conductivity thereof can not be obtained in < the lower limit of the addition ratio of the above- mentioned sintering auxiliary. The above-mentioned values of the density and the thermal conductivity are reduced because of inhibition of sintering in > the upper limit.

Title: Power unit for electronic equipment
Inventor: NAKAYAMA HIDE
IPC: G05F1/10
Filed: 1989-08-09
Abstract: PURPOSE:To stably operate electronic equipment in a wide temperature range by controlling a temperature in the equipment without using a heater, etc., by providing a second power source part to supply a prescribed power out of powers outputted from a first power source part to a load and to convert another power to heat loss between the first power source part and the load. CONSTITUTION:The first power source part 1 detects the temperature with a sensor part 4 and changes an output voltage based on the change of its output signal. In other words, under the condition of low temperature, the change of the output signal of the sensor part 4 raises the output voltage of the first power source part 1 higher than the one under the condition exceeding a room temperature. Meanwhile, the second power source part 2 supplies the prescribed constant power out of the output powers to the load 3, and changes another power to the heat loss. Therefore, when the output voltage of the first power source part 1 is increased under the condition of low temperature, the heat loss is increased by that amount, which raises the temperature in the electronic equipment with the heat loss. In such a way, the equipment can be stably operated.

Filed: 1989-08-11
Abstract: PURPOSE:To realize constant speed control of a motor and to improve the maintainability and the reliability of operation by outputting a frequency correction value signal based on a detected value of input current to inverter section and controlling the output frequency of the inverter section based on the frequency correction value signal. CONSTITUTION:A frequency correction circuit 17 outputs a frequency correction value signal according to the variation of the value of current detected through a current detector 16. When load torque increases under steady operation, slip increases to cause increase of input current thus increasing frequency correction value signal to be fed from the frequency correction circuit 17. Consequently, such signal as the frequency correction value signal is lapped over a set signal, fed from a frequency setter 15, is provided through an amplifier 22 to a frequency control circuit 25. The frequency control circuit 25 controls the output frequency from the inverter section 13 to increase by the amount of the frequency correction value signal. By such arrangement, speed drop of the motor 14 is compensated and constant speed control is carried out.

IPC: H01L21/28
Filed: 1988-08-19
Abstract: PURPOSE:To produce a stable contact which causes no junction leak even upon application of heat in succeeding processes by subjecting TiN or TiW coated as a burrier metal to high speed thermal processing under a environment containing inert gas and oxygen gas. CONSTITUTION:At first, a Si substrate 101 is coated with an insulation film 102 and an opening is made therethrough. Then a burrier metal 103 is formed through sputtering. TiN or TiW is employed as the burrier metal. When TiN is employed, a halogen lamp annealing device is used for carrying out high speed thermal processing under an environment containing inert gas and oxygen gas. At this time, the temperature is brought higher than 700 deg.C. Oxygen gas flow is reduced as low as possible in order to prevent oxidation of TiN. Thereafter, a conductive wiring layer 105 is formed of Al alloy, for example, through sputtering. By such arrangement, junction leak does not occur even upon application of heat in the succeeding processes.
