Title: Detecting circuit for velocity pulse
Inventor: SAKUYAMA HIDEO
IPC: B60L9/16
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To perform the accurate and stable detection of velocity over the full range of velocity with less dispersion in the frequency computation of velocity pulses. SOLUTION: In this detecting circuit, the number of edges of a velocity pulse in two phases A and B (with a phase difference of 90 deg.) and time data at the time of edge detection are detected to compute the frequency of a velocity pulse by a microcomputer 14. In this case, the detecting circuit is provided with a correcting means 7 which performs correction so that the time of a velocity pulse at high/low levels are averaged, a both-edge detecting means 8 which detects both edges of rising and falling of the A phase and B phase, a single edge detecting means 9 which detects the single edge of only the A phase of a velocity pulse, and a switching register 5.  The detection of a velocity pulse is performed by the both-edge detecting means 8 via the correcting means 7 at the time when the frequency of a velocity pulse is within a computation period and by switching to the single edge detecting means 9 at the time when the frequency of a velocity pulse is more than the computation period.

Abstract: PURPOSE:To prevent an I type iron core from slipping out by a method wherein the protrusions simultaneously integrated with molded bobbins are made slightly thicker than the dimension of a linkage gap made between the I type iron core and E type iron cores so as to fix the I Type iron core. CONSTITUTION:The protrusions 5 integrated with molded bobbins 4 are made slightly thicker than the dimension of the linkage gap 3 made between E type iron cores 1 and an I type iron core 2. Accordingly, when the I type iron core 2 fitted with the molded bobbins 4 is held and pressurized by two each of the E type iron cores 1 from both sides, the protrusions 5 are deformed by the pressurization in the state of being held by the E type iron cores 1 and the I type iron core 2 so that the I type iron core 2 may be pressurized from both sides through the intermediary of the protrusions 5. At this time, the thin wall parts 8 adjacent to the protrusions 5 concentrate the pressure applied on the protrusions 5 by the E type iron cores 1 in themselves 8 so as to prevent the molded bobbins 4 from breaking down due to the deformation such as distortion etc.

Abstract: PROBLEM TO BE SOLVED: To provide a noise reduction device capable of effectively reducing noise components not only in still images but also in moving images without a blur feeling due to the degradation of high band components and being realized at a low cost. SOLUTION: An upper limit detector 8 ranks the size of the signal level of reference pixels composed of plural peripheral pixels with a center pixel as a center in input video signals and detects the signal level of the pixel of an upper limit value rank R1 set larger than a center rank. A lower limit detector 9 detects the signal level of the pixel of a lower limit value rank R2 set smaller than the center rank. An MIN 10 and an MAX 11 constitute an amplitude limiting means and amplitude-limit the signal level of the center pixel between the upper limit value rank and the lower limit value rank. As a result, amplitude change by noise is suppressed.

IPC: G01B21/22
Filed: 1997-03-18
Abstract: PROBLEM TO BE SOLVED: To provide an oscillating motor having a larger rotor torque by causing a drive coil 15 to utilize effectively magnetic fluxes generated by magnets. SOLUTION: A rotor 14 is constituted by fitting magnets 12, 13 with two poles in the radial direction, to a shaft 11 rotatably supported by bearings. A driving coil 15 for oscillating the rotor 14 in a range of a specified angle is arranged along the lengthwise direction of the peripheral surfaces of the magnets 12, 13, and along the upper and lower surfaces of the magnets 12, 13 as well. Consequently, the length of the part to which magnetic fluxes from the magnets 12, 13 act effectively in the whole of the driving coil 15 becomes longer than the length in the axial direction of the magnets 12, 13 as shown by the figure. Accordingly, it becomes possible to increase the torque of the rotor 14, since the driving coil 15 can effectively use magnetic fluxes generated by the magnets 12, 13.

Abstract: PURPOSE:To transmit what a patient intends to others by detecting it by an eyeball motion detector that his eyes are turned on a specific gaze point. CONSTITUTION:The patient wears an eyeball motion sensor 2, and the sensor output signal obtained by watching a presentation monitor 8 is introduced to an eyeball motion analyzer 4. The sensor 2 and the analyzer 4 constitute the eyeball motion detector.

When the next sample point is in a circle prescribed by VthX(sampling period), it is discriminated that he sees the gaze point in the center of the circle. When his eyes are turned upon a point on the outside of this circle within one sampling time, it is discriminated that he averts hie eyes from the gaze point. The output signal of the analyzer 4 is subjected to a prescribed processing by a processor 6, and the result is presented on the presentation monitor 8 again.

Title: Netlike form device
Inventor: SAINOO TAKASHI
IPC: E02D29/02
Filed: 1993-04-13
Abstract: PURPOSE:To make it possible to eliminate the need for a separator, prevent the deflection due to the weight and side pressure of concrete filled in the interior, and improve construction efficiency by erecting and fixing a vertical end thick material on the outer side and locking the material by means of a locking member. CONSTITUTION:When concrete is placed, predetermined vibration is applied to fill the concrete uniformly into a form. In this case, vertical end thick materials 10 are firmly fixed on the outer sides to prevent netlike form members 12 from being deflected outwards. Next, after predetermined curing period of time, the solidified concrete is removed from the form. As a result, there is no need to attach a separator and hence rust or water leak at an attaching part can be avoided, thereby shortening a construction period.
