CONSTITUTION:A rubbery bellows tube 7 is fitted into an inner tube 6 provided to the rear side wall 4 of a box-like frame body 1, and an intake port 8 consisting of rigid plastic tubes is provided at the tip of the tube 7. When water form a water channel flows into a paddy field from the intake port 8 and the water level rises, the float 22 of a water level detection mechanism 20 goes up to the water surface, the coupling of coupling levers 14 and 16 are released in the place where a rope 23 is tensed, the intake port 8 is uncoupled and exposed to the water surface by the buoyancy of the float 10, and thereby the inflow of water to paddy field is stopped. In this case, the intake port 8 does not go down because it is coupled with any of the multi-stage coupling recessions 19 of the coupling lever 16. When the intake of water is needed, the coupling between the coupling lever 16 and the intake port 8 is released, the rope 23 is loosened, and the coupling levers 14 and 16 are connected to each other.

Title: Magnetic recording medium
Inventor: SATO RYOICHI
IPC: G11B5/706
Filed: 1986-03-24
Abstract: PURPOSE:To obtain an excellent magnetic recording characteristic by providing a magnetic layer contg. magnetic particles of a hexagonal barium ferrite having a specific value or above of the specific transmittance of a specific wavelength on a nonmagnetic base. CONSTITUTION:A magnetic recording medium is formed by providing the magnetic layer contg. the pulverized magnetic particles of the hexagonal barium ferrite on the nonmagnetic base. This magnetic layer is so formed that the specific transmittance T(800) per 1mum of the light of 800mum wavelength attains >=30%. The reason for specifying the transmittance T(800) of the light per 1mum of the magnetic layer to >=30% lies in that the ratio of the recording and reproducing output-to-noise exhibits a good value at the specific transmittance T(800) or above. The dispersibility is better as the transmittance of the light is larger with the same compsn. There is a correlation between the dispersion of the magnetic material of the hexagonal barium ferrite formed on the nonmagnetic base into the magnetic powder in the magnetic layer and the transmittance of the light. The magnetic recording medium having the excellent magnetic recording characteristics is thus obtd.

Title: Track searching method for magnetic recording and reproducing device
Inventor: MAEDA YUTAKA
IPC: G11B27/10
Filed: 1988-03-22
Abstract: PURPOSE:To reduce the time required by the title device for making track search by previously fixing envelope detecting positions to be fixed in the course of track searching to a rotating magnetic recording medium on each track in a limited state. CONSTITUTION:In the course of a track searching process, if the level of detecting signals of an envelope detecting circuit 83 does not reach a prescribed threshold level when a magnetic head is moved in the direction crossing tracks, the crossed tracks are discriminated as unrecorded tracks. In order to reduce the track search processing time, the positions for detecting the envelope of reproduced signals are limited to -2 pulse, '0' pulse, and +2 pulse positions on each track and the envelope detecting process is performed in the described order. When the envelope is detected at one of the limited envelope detecting positions, the track is discriminated as a recorded track and no envelope detection is performed at the remaining envelope detecting positions of the track.

IPC: G06F17/40
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To quantify significant difference and to make it clear by performing Freedman's test which decides conformity of inputted order data and performing Wilcoxen's signed order sum test which decides the relation of order of each sample when it is decided that significant difference exists with respect to conformity. SOLUTION: When Wilcoxen's signed order sum test S3 can not decide that there is significant difference to any of two samples, Man Witney's order sum test S5 is performed. Plural given samples are divided into some appropriate groups and the existence of significant difference among groups is decided. Grouping, for instance, is performed by comparing average values of order data of each sample that is calculated at the time of Freedman test. Every two groups among plural groups calculate appearance probability P value of Man Witney's order sum test, decide that significant difference exists and make ordering between the two groups clear.

Title: Surge receiving type fault point orienting device
Inventor: NAKAMURA TAKESHI
IPC: G01R31/08
Filed: 1981-04-30
Abstract: PURPOSE:To ensure electric insulation for the main body of a fault point orienting device, etc. and to eliminate malfunction, etc., by converting a fault surge voltage or a current into an optical signal and then transmitting the optical signal to a fault point orienting device from the side of a capacitor type voltage divider via an optical fiber. CONSTITUTION:When a bus L has no fault and in the normal condition, voltage division is carried out for a driving power supply device E by means of a coupling capacitor C1 and a commerical AC power supply capacitor C2. The divided voltage is applied to an AC-DC converter via an insulated transformer T1 to be converted into a DC and then supplied to an electrooptic converter E/O through  a surge absorbing capacitor C4. If a fault arises in the bus L, the fault surge is transmitted to a voltage dividing device CD and the converter E/O to be compensated and amplified through a driver DV with the output supplied from the device E used as a power supply. Then a light emitting diode LED1 is actuated. This optical signal is converted into an electric signal through an optical fiber LG and the converter O/E and then applied to the main body LC of a fault point orienting device. Thus the fault point is oriented.

Title: Automatic control unit
Inventor: YOSHIDA FUMIO
IPC: B21B37/18
Filed: 1979-05-25
Abstract: PURPOSE: To establish the press-down control position less in phase difference between the reference value and the press-down position, by adding a unit correcting the value of press-down position reference.  
     CONSTITUTION: A differentiating unit 16 outputs the mobile speed of a press-down reference value ΔSa, and the mobile speed is limited to the mobile speed to which the press-down position ΔS can follow by a limiter 17. An integrator 18 integrates the differentiated output from the differentiating unit 16 via the limiter 17 to obtain the output ΔSb to a press-down control system 7. While the change rate of the reference value ΔSa is small, since the differentiation 16 of the reference value ΔSa does not reach the limit value of the limiter 17, the integration output ΔSb is integrated 18 as it is, and ΔSa and ΔSb are of the same waveform. Further, if the changing rate of ΔSa is great, since the output differentiating 16 the ΔSa is integrated 18 after it is limited with the limit value of the limiter 17, the changing rate of ΔSb is limited. But, even in this case, the phase of ΔSa and ΔSb is in agreement. Accordingly, the phase of ΔSb and ΔS can be in agreement.

Title: Call signal detector
Inventor: KITAO MASAYUKI
IPC: H04M11/00
Filed: 1988-03-18
Abstract: PURPOSE:To reduce the execution time of a CPU and to improve the processing efficiency by outputting a detection signal when a call signal is received and detecting the presence or absence of a pulse signal in a 1st time interval longer than the period of the pulse signal included in the call signal and stopping the output of the detection signal when the pulse signal is not detected in the predetermined 2nd time. CONSTITUTION:A CPU 7 sets a flag FG to 0 in the main routine to allow the interruption of a call signal and awaits the call signal interruption. When a call signal interruption takes place, the CPU 7 applies sampling for each time interval TS. when the H level is detected, the flag FGH is set to 1. The sampling is applied at least twice during the pulse transmission time T1. When the H level is not reached as the result of sampling, the time T not detecting the pulse signal is counted and when the time T exceeds the set time, the flag FG is set to 0 and the interruption of the call signal is allowed again. Thus, the load of the CPU is relieved and the processing efficiency is improved.
