Title: Motor-driven fluid machinery and frequency converter used for the fluid machinery
Inventor: KOBAYASHI MAKOTO
IPC: F04D13/08
Filed: 1996-05-09
Abstract: PROBLEM TO BE SOLVED: To eliminate a useless operation by storing drive modes made to contain the speed, operation time and rest time of a motor as elements, and performing operational control via the selection of one of the drive modes on the basis of the specific gravity of fluids, regarding a machine to draw a plurality of fluids having different specific gravity. SOLUTION: At the time of starting a pump, a priming plug 26 is preliminarily removed and then a barrel 1 is replenished with self-priming for storage in annular space (delivery chamber) 8. Then, the pump is started. As a result, the priming is drawn into a pump easing 11 via a self-priming circulation water suction port 23 open to the annular space 8. Also, an air-water mixture of the air at the suction side and the priming drawn from the suction port 23 is pressurized with an impeller 12, and discharged from a delivery port 24 to the delivery chamber 8. In this case, consumption torque per revolution is detected to find the specific gravity of a fluid. Furthermore, the most effective drive mode is selected depending on a fluid to be drawn, on the basis of the specific gravity.  For example, a high speed rotation mode is selected at the time of drawing the air of low specific gravity, while a low speed rotation mode is selected at the time of drawing water of high specific gravity.

Title: Method for growing single crystal
Inventor: ASAHI TOSHIAKI
IPC: C30B11/00
Filed: 1992-05-06
Abstract: PURPOSE:To prevent the polycrystallization from a vessel wall during the growth of a crystal by filling a melt of nearly the same compsn. as the compsn. of a raw material melt between a vessel for growth and an outer vessel and cooling the raw material melt to solidify. CONSTITUTION:The vessel 6 for growth is arranged in the outer vessel 5. The raw material melt is put into this vessel 6 for growth and the melt of nearly the same compsn. as the compsn. of the raw material melt is filled between the vessel 6 for growth and the outer vessel 5 closely up to about the same height as the height of the raw material melt. The melts in and out of the vessel 6 for growth are then simultaneously cooled to solidify and to allow the crystal to grow. As a result, the direct heat release in and out of the vessel for growth is lessened and the reverse projection of the solid-liquid boundary on the wall of the vessel for growth is prevented. The single crystal is thus grown with good reproducibility.

A reproducing signal from an R/W head Hrw is detected as to the amplitude of a pulse corresponding to an embedded servo-signal by a peak detector 12, A/D-converted 13 and inputted to the PC 1. In the PC 1, a position detecting signal is formed, and this signal and a position reference signal from a terminal 15 are added 24, so that the position detecting signal becomes the same level as the position reference signal, integrated 17, brought to phase compensation 17, and a driving current is supplied to the ACT 10 so that the center of the head Hrw coincide with the center of a track.

Title: Output protection circuit
Inventor: SUZUKI TAKESHI
IPC: H03K17/08
Filed: 1986-06-16
Abstract: PURPOSE:To obtain a high dielectric strength without losing the drive capability by providing plural protection circuits each comprising a protection resistor having a comparatively high resistance and a protection diode in parallel between a drain and an output pad of an output MOS transistor (TR) so as to scatter a surge thereby preventing the concentration onto a specific part. CONSTITUTION:In selecting resistors R1-R4 to the same and comparatively high value and the pattern similarly, and selecting diodes D1-D4 as similar pattern and characteristic, a surge voltage is scattered into four protection cicuits 131-134 and then absorbed. Thus, the concentration of stress onto a specific pattern is prevented. Since the protection resistors R1-R4 are connected in parallel between the drain of the output MOS TR Q3 and the output pad 12, the combined resistance is lowered, the drive capability of the output circuit is not decreased. Since the resistance of the resistors R1-R4 is high, an overcurrent is suppressed sufficiently to offer a high protection effect. a, from internal circuit.

Title: Cassette tray
Inventor: NAKAMURA MITSUNORI
IPC: G03G15/00
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent an area with formed images of a recording medium from deviating from a proper area by freely moving a side regulating plate by a prescribed distance in a width direction in a state that the side regulating plate is fixed by a fixing means. SOLUTION: In a side regulating plate 22 and a fixing means 90, a side regulating side cam and a fixing means side cam for separating positions of the plate 22 and the means 90 each other at the time of rotation are formed. Because the front side regulating plate 22 is energized in a direction that the front side regulating side cam and the fixing means side cam are separated by a compressive coil spring in a fixing state, the front side regulating plate 22 is capable of freely moving in an arrow B direction according to stress acting on the front side regulating plate 22. Therefore, the front side regulating plate 22 and a rear side regulating plate 24 are capable of moving by a prescribed distance in a width direction (the arrow B direction) in a state that the plates 22 and 24 are fixed by the fixing means 90.  Even if the recording medium is strongly pressed on the side regulating plates 22, 24, a slight gap is formed because the recording medium pushes back the side regulating plates 22, 24 in the width direction.

Filed: 1983-07-29
Abstract: PURPOSE:To attain long time backup by storing the sum of a fixed pattern and necessary data in an idle address of a memory or an area of a working memory when voltage supply from a main power supply is interrupted. CONSTITUTION:When the main power supply is turned off during an operation, voltage is supplied to a microcomputer 1 by the discharge of a backup capacitor 4. At that time, the microcomputer 1 stores the sum of the fixed pattern having previously fixed random number and the contents of data requiring backup in the idle address of the memory 17 and the memory address in the working area which is not used in the time other than real operation. When voltage is supplied from the main power supply 13 again, a reset signal is impressed from a node between a capacitor 20 and a resistance 21 to the microcomputer 1. If the backup is executed in the operation voltage range of the memory 17, the contents are held as they are even if the backup is reset on the way and then the operation starts again, so that the contents are guaranteed.

Title: Measurement of radiation dose
Inventor: UDA TATSUHIKO
IPC: G01T1/02
Filed: 1985-06-28
Abstract: PURPOSE:To surface-monitor an alpha-radioactive waste by oscillating an electret element at a constant period and converting to a piezoelectric output based on an electric charge induced on the surface of a piezoelectric element opposite to the electret element through an insulative dielectric layer to thereby obtain the quantity of a radiation. CONSTITUTION:After the surface of an object contaminated by an alpha-radioactive or beta-and-gamma-radioactive substance is covered by a permanently polarized electret film 10 for a given time, the film 10 is connected to an AC power supply via an electrode 11 for oscillation on one end of the film 10. Further, the film 10 is opposed to a piezoelectric element 13 in a close contact with an output electrode 14 via a dielectric layer 12. Since the gap of the dielectric layer 12 is changed when the film 10 is oscillated, the quantity of an induced charge is changed by an oscillatory period. Therefore, a piezoelectric output synchronizes with the oscillation of the film 10. The output of the power supply 15 for oscillation is rendered a reference signal 16 and only a synchronous output component, after amplified by a phase detector 17, is outputted at a recorder or a display 19. A measuring portion is contained in an electrostatic shielding casing 20 to remove the effect of a disturbance. Thus, a surface contamination monitor especially for an alpha-radioactive waste can be performed.
