IPC: B22F3/02
Filed: 1994-11-10
Abstract: PURPOSE: To produce a porous metal with a simple process by sintering a porous material contg. a slurry consisting of an aq. agar soln. and a metal powder and which is burned off below the sintering temp. of the metal powder. CONSTITUTION: About 20g of solid agar is added to 1000cc of water in a vessel 1, for example, and mixed by an agitator 2 to obtain an aq. agar soln. A. About 300cc of the soln. A is transferred to a vessel 3, about 1kg of stainless steel powder having about 10μm average grain diameter is added, and the mixture is agitated by an agitaor 4 to prepare a slurry B. The slurry B is then transferred to a shallow vessel 5, a porous material 6 of a polyurethane foam having about 30mm thickness is placed in the vessel 5, and the porous material 6 is impregnated with the slurry B. The porous material 6a is pressed by squeeze rollers 7a and 7b to remove the excessive slurry B from the porous material 6a and cooled to room temp., and the agar component is gelled.  The gel is dried, the dried porous material 6b is put in a sintering furnace 8, the furnace is evacuated, and the porous material is sintered at about 1000 deg.C for about 120min to obtain the objective porous metal 9.

Title: Magnetic bearing controller
Inventor: HIROSHIMA MINORU
IPC: F16C32/04
Filed: 1991-11-18
Abstract: PURPOSE:To reduce rigidity of a bearing and avoid passing of resonant vibration by activating a notch filter at a predetermined engine speed during operation of a rotary machine on the basis of a signal output from a rotation detector. CONSTITUTION:A rotation detector 11 detects an engine speed of a rotating body. A comparison circuit 12 compares the detected speed with an engine speed previously set by a reference engine speed setter 13. A signal for operating a notch filter circuit 5 is output when the comparison result reaches the set value. The notch filter circuit 5 is connected in series to a proportional circuit 2, an integrating circuit 3 and a differentiating circuit 4 on the basis of the signal. The operation of the notch filter circuit 5 can deteriorate rigidity of a bearing so as to decrease a resonant frequency of the rotating body. Consequently, operation can be carried out while avoiding the resonant frequency, thereby reducing vibration generated in the rotating body. Therefore, it is possible to miniaturize a bearing main body and a power amplifier for controlling with reduced force required for magnetic bearing control.

Title: Electronic photograph device
Inventor: ITO KEIZO
IPC: G03G21/00
Filed: 1990-11-07
Abstract: PURPOSE:To prevent the occurrence of bad fixing even in a case in which the lowering of the voltage of a power source is remarkable, by setting the deceleration degree of a processing speed according to the power source voltage. CONSTITUTION:When a copy paper sheet B passes a fixing portion 7, heat is taken away at the time of the fixing of a toner image, so a fixing temperature at the portion 7 comes to lower gradually from a target temperature T0 after time t3. And when the fixing temperature lowers to a deceleration temperature T2 at time t4, a control portion decides that the fixing temperature is lower than the deceleration temperature, and conducts the detection of power source voltage. Next, the deceleration degree of a copying speed is set according to the power source voltage thus detected. Thus, the more the power source voltage is lowered, the slower the copying speed is made to be, so it is eliminated that the fixing temperature lowers more than the deceleration temperature T2 and reaches a fixing lower limit temperature T3.

Title: Data reader
Inventor: YOSHII MASAHIRO
IPC: G06K17/00
Filed: 1990-11-06
Abstract: PURPOSE:To execute business when fluctuation of a power supply is slight and improve business efficiently by providing a waveform monitor section with a means detecting a voltage level at least at two stages and a means discriminating the change of voltage waveform stepwise through a measuring means to measure a continuous period of time of change of voltage level. CONSTITUTION:When data loading medium 2 is inserted in data reader 10, via switch section 13 and connecting section 14 power supply 12 supplies the loading medium 2 with power. A waveform monitor 15 always monitors the voltage waveform of the power supply. If it is judged that the voltage waveform fails, a control section 16 informs an upper level terminal of a result of the judgement. That is, if the output from a detecting means 17 exceeds a first voltage level range and less than a second voltage level range and the continuous time of voltage fluctuation of a measuring means 18 is within a set period of time, a discriminating means 19 outputs a state signal to the upper level terminal 11 via the control section 16, and on the other hand, if the continuous time of voltage fluctuation of a measuring means 18 is out of a set period of time, the means 19 outputs the first state signal, and if the output of the detecting means 17 exceeds the second voltage signal level range, the discriminating means 19 outputs the second state signal to the upper level terminal 11. Thus, the monitor 15 discriminates the fluctuation of voltage waveform stepwise.
