Title: Control valve
Inventor: SAKO MITSUSATO
IPC: F16K31/02
Filed: 1988-05-25
Abstract: PURPOSE:To enable fluid to be completely interrupted at the time of entire closing as well as to make a device compact by rotating a rotating cylinder piled upon a stationary cylinder by means of the stator of a piezo-electric motor so as to enable the openings of both of the cylinders be communicated with each other, and thereby sealing both of the cylinders with magnetic fluid. CONSTITUTION:When a rotating cylinder 6 is rotated against a stationary cylinder 5 with the stator 7 of a piezo-electric motor driven, an opening area communicating the opening 5a of the stationary cylinder 5 with the opening 6a of the rotating cylinder 6 is changed so that the flow-rate or the pressure of fluid flowing within a valve main body 1 can be controlled. And when the openings 5a and 6a of the stationary cylinder 5 and the rotating cylinder 6 are entirely uncommunicated with each other, the valved is entirely closed. In this case, since there exists magnetic fluid 15 around the opening 5a of the stationary cylinder 5, even if there is a gap more or less between the stationary cylinder 5 and the rotating cylinder 6, the gap can be sealed by the magnetic fluid 15. No fluid leak therefore develops, thereby enabling the fluid to be completely interrupted.

Filed: 1988-05-26
Abstract: PURPOSE:To smoothly start a facility by starting a hydraulic machine, interposing a generator in an electric system, thereafter changing a time constant of speed control circuit at the point where the matching at the time of interposing is cleared over a second value, and moving operation to the normal while delaying the response. CONSTITUTION:When an aimed output is input to an output controller 1 based on a power generation command, the controller 1 computes the aimed rotary speed corresponding to the aimed output to generate a command to an opening controller 2, thereby a guide vane 3 is operated and a runner 4 is rotated. The rotary speed of an induction generator 5 directly coupled to the runner 4 is detected by a speed detector 6. A speed control circuit 7 outputs a control signal to a speed controller 8 in response to the difference between the actual rotation speed of detector 6 and the aimed rotary speed of controller 1. In this case, after the induction generator 5 is interposed in an electric system, the time constant of speed control circuit 7 is changed over a second value at the point where the shock at the time of interposition so as to speed up the response.

Filed: 1990-05-18
Abstract: PURPOSE:To prevent the sticking of toner to a developer detecting window by monotonously reducing the distance of the detecting surface of a developer concentration detector and the developer carrier as it goes to the downstream side in the advancing direction of a developer. CONSTITUTION:In the developer concentration detecting window 33 of a detecting unit 30, a surface facing a developing sleeve 251 is inclined by the angle of theta with respect to the contacting line of the developing sleeve 251, and the opening part A of the entrance side of the developer T carried on the developing sleeve 251 is larger than the opening part B of the exit side. Since the detecting surface of the detecting window 33 is formed flat, the distance of the detecting surface and the developing sleeve 251 can be monotonously reduced as it goes to the downstream side in the moving direction of the developer. Therefore, the detecting surface of the detecting window 33 detecting the concentration of the developer is not eternally soiled by the developer. Thus, the concentration of the developer is always and accurately detected, and a stable developer concentration is always obtained, and an uniform high- definition image is obtained.

Abstract: PURPOSE:To obtain an apparatus which enables the detection of a speed signal with limited ripples along with a better response by switching and differentiating outputs of a rotary encoder. CONSTITUTION:Outputs A0 and B0 of a 2-phase type rotary encoder are inverted 2 and 3 separately. Then, the outputs A0 and B0 are added up 8 while the inverted output A0 and output B0 are added up 9 and based on respective addition outputs, a logic processing 14 is performed to obtain four kinds of outputs sequentially during one cycle. Then, respective outputs inverted and non-inverted are differentiated 4 to be applied to a switching circuit 6, with which differentiated values of the outputs are trimmed near the maximum of the minimum thereof based on the four logic outputs. These switching outputs are differentiated 5 and the harmonic components of the differentiation outputs are removed with a filter 7. As a result, a DC voltage can be detected which varies in the polarity with the direction of rotation while proportional to the rotational speed from the outputs of the encoder.

Title: Floating magnetic head
Inventor: EZAKI KIICHIROU
IPC: G11B21/21
Filed: 1992-04-23
Abstract: PURPOSE:To improve follow-up characteristics by forming a floating surface of a slider in a flat state over the entire surface. CONSTITUTION:A floating surface 105 of a slider 1 is opposed to a magnetic recording medium, and a reader/writer 2 is mounted. The floating surface is formed substantially in a flat state over the entire surface. Accordingly, when a loading point is set to an intermediate part of the slider, floating amounts become substantially equal at air input and output sides thereby to avoid a front lowering. Even if the floating amount is 0.2mum or less, it is scarcely crashed, and magnetic head having high recording density can be obtained. Since the floating surface is flat over the entire surface, masses are balanced before and after the loading point set to the intermediate part of the slider, an inertial moment of the entire head is reduced. and a high speed follow-up can be obtained.

Then the values corresponding to those set edge areas are set to the RAM45 and a flag counter 42.

Title: Variable delay circuit
Inventor: YAMAGIWA AKIRA
IPC: H03K5/13
Filed: 1982-07-28
Abstract: PURPOSE:To attain high accuracy and high stability, by eliminating the difference in delay time by using a differential circuit for a driving circuit, taking balance between the rising and falling times and avoiding the change in pulse width even if the delay time is large. CONSTITUTION:The driving circuit 11 is a bipolar circuit and a CR circuit comprising a resistor 12 and a varactor diode 13 is formed to each output. A bipolar signal from each CR circuit is inputted to a differential input type receiving circuit 11' of the next stage to perform waveform shaping. A voltage applied to the varactor diode 13 is given via a DA converter 14. The delay time is changed by changing an input D of the DA converter. When a reverse bias voltage is small and the capacitance is large, even if the waveform at points A and B is different between the rising and falling times since the receiving circuit 11' is formed as a differential input, no difference in the increment of delay time is produced between the rising and the falling times at outputs O1 and O2.

Filed: 1986-06-05
Abstract: PURPOSE:To prevent the effect of a trouble to other operation and to easily study the trouble factor by detecting an interface trouble in response to a fact a discrepancy state lasts longer than a prescribed time between the number of requests transferred between the information processors and the number of replies. CONSTITUTION:The requests given to an information processor 2 from an information processor 1 via a signal line 9 of a monitor system are counted by a counter circuit 3.

A comparator 5 compares the count values of both circuits 3 and 4 with each other. A timer 6 is set according to the result of said comparison and then reset by the output of an OR circuit 8. If the discrepancy between both count values of circuits 3 and 4 lasts longer than a prescribed time, an alarm device 7 works to prevent the effect of an interface trouble to other operation. Thus the factor of the trouble is easily studied.
