Title: Preparation of porous glass
Inventor: KUROSAKI SHIROU
IPC: C03B37/00
Filed: 1979-12-20
Abstract: PURPOSE:In eluting separated phase glass with an acid, to prepare porous glass having no extraordinary point (wherein the diameters of micro pores are extraordinary large), by maintaining the surroundings of one part of the glass at high temperature, and the surroundings of another part of the glass at low temperature. CONSTITUTION:The leaching solution (e.g., hydrochloric acid solution) 37 is put in the bath 36 which is divided into the area A and the area B by the dividing plate 31, and a phase separated glass rod 30 is inserted in the middle of the dividing plate 31 and supported. The phase separated glass rod 30 is leached, while the solution of the area A being heated by the heater 32, and the solution of the area B being cooled by passing cooling water through the cooled part 34 (the arrows 33 and 35 show the circulations of the high-temperature and low temperature solution srespectively). By the above-mentioned method, since the leaching rate of the phase separated glass 30 is higher in the side A than in the side B, the navel 38 at the striking position of the progressing face of the leaching is produced on the surface of the side B (the low-temperature side). This can be removed simply by surface grinding.

IPC: F03B15/08
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To shorten the starting time of hydraulic turbine generator having low inertia. SOLUTION: In this device, the magnetic field of a synchronous generator 1 is controlled by an AC exciter 2 and a rectifier 3. The magnetic field of the AC exciter 2 is controlled by an AVR 7. An electric governor control device 5 is used for control of the speed of a water turbine having low inertia (GD<2> ). Feedback of a difference (a governor deviation) between a speed detecting value and a speed set value to the AVR 7. Namely, a difference between the detecting value (the output of a PT6) of the output voltage of the generator 1 and the set value of an AVR setter 7A is compared with a governor deviation and a difference therebetween is inputted to the AVR 7.  This constitution reduces an AVR input during starting by a governor deviation (increased to a high value during starting), gently reduces the increase of an output voltage, and prevents the occurrence of fall phenomenon of the number of revolutions of a water turbine. Thus, a starting time (a voltage establishment time) is shortened.

Abstract: PURPOSE: To provide an actuator, which reduces energy cost and automatically attains specified end position when switch off or stop for failure by providing a permanent magnet and electromagnet at a closed position and an opening magnet having an electromagnet only. CONSTITUTION: The actuator comprises working magnets 1, 2, coils 3, 4 and a permanent magnet 5. The current in the coil 3 of a closing magnet 1 weakens the magnetic field action of the permanent magnet 5 on an armature 6.

At time t2 to feed a current to the coil 4 of the opening magnet 2 at correct timing, the actuator is attracted to a pole face. After cutting off the current to the coil 4, a short delay time elapses while the magnetic field weakens the spring force. At time t3 the actuator moves and at time t4 due to the magnet force it is attracted and held, based on a magnetic field generated by the permanent magnet.
