Title: Controller of pwm inverter
Inventor: MAEKAWA KATSU
IPC: H02M7/48
Filed: 1985-02-27
Abstract: PURPOSE:To reduce low order harmonic wave content by using as a reference wave a digital sinusoidal wave at large output voltage time and a PWM signal pulse-width-modulated so that the average value becomes the desired sinusoidal wave at fine voltage output time. CONSTITUTION:A switching element of an inverter 1 is turned ON and OFF to convert a Dc constant-voltage power source 2 to a 3-phase AC voltage to drive a 3-phase induction motor 3. The controller of the inverter 1 has a frequency setter 4, a V/F converter 5, a counter 6 as shown, and is controlled by PWM. Thus, when obtaining a relatively large output voltage, a reference wave generator 9 outputs 3-phase digital sinusoidal waves having a voltage command value ¦V¦ in amplitude and equal in the frequency to the set frequency, and the output voltage of the inverter 1 is pulse-modulated in sinusoidal wave. At fine voltage output time, a PWM signal pulse-width-modulated to becomes a desired sinusoidal wave in the average value is used as a reference value to be pulse-width-modulated.

Abstract: PURPOSE:To remove an excessive Si condition, and to obtain an excellent Si3N4 film by implanting N2 or O2 ions in the Si3N4 film and annealing the surface through radiation treatment or heat treatment. CONSTITUTION:A SiO2 film 2 with approximately 20Angstrom  thickness is grown on a Si substrate 1, and the Si3N4 film 3 with approximately 450Angstrom  thickness is laminated and coated onto the film 2.

The surface is annealed by energy in the extent of approximately 1.2Joule/cm<2> by using a Nd:YAG laser. Accordingly, the N2 or O2 ions implanted are bonded with the excessive Si while a flow generated at the time of implantation is also repaired, and the Si3N4 film 4, which contains no excessive Si and characteristics thereof are excellent, is obtained.

Title: Method and apparatus for transporting liquid in boilng stage or in vicinity of boiling state
Inventor: SASA CHIYOUSEI
IPC: F04D7/06
Filed: 1980-03-26
Abstract: PURPOSE: To prevent cavitation and to facilitate the transportation of liquid to a high pressure side by circulating boiling-point liquid via a dynamic and static pressure converter, providing a boiling-point liquid take out nozzle between a pump delivery port and a dynamic and static pressure converter inlet port, and obtaining pressure head of circulating liquid.  
     CONSTITUTION: When a motor 2 of a pump 1 is driven, pressure of returning water in a system is boosted by the pump 1 and flows into a drum 10 through an inlet nozzle 8 of the dynamic and static converter 7 and an upper convolution chamber 9 at a high speed. The pressure head of the returning water which is compressed by the pump 1 is converted to speed head, descended through the drum 10 with intense free convolution being accompanied, and enters into a lower convoluting chamber 11 and lower diffuser 12. The speed head is again converted to the pressure head and the pressure is increased. The pressure is applied to an intake 5 of the pump 1 via a communicating pipe 3. Cavitation of the pump 1 is prevented even though the circulating current is under the boiling state. Thus, the boiling-point liquid can be readily and stably transported to the high pressure side.
