Title: Recording and reproducing device for wide band luminance signal
Inventor: TANAKA KAZUNORI
IPC: G11B20/02
Filed: 1988-03-16
Abstract: PURPOSE:To improve the resolution at the time of reproduction by recording a narrow band luminance signal obtained by compressing the band of a wide band luminance signal to about 1/2, and a sampling frequency signal on a recording medium and reproducing the luminance signal to convert it to a signal having two-fold horizontal scanning number and using this signal and the converted signal of one horizontal scanning period before to restore the wide band luminance signal. CONSTITUTION:A wide band luminance signal Y and a color signal C separated from a color video signal are inputted to an input terminal 1, and the signal Y has the band compressed to about 1/2 by dot interlacing of a modulator 2. A compressed luminance signal Y' and the color signal C are recorded on a VTR 3, and jitter is removed by a time base corrector 5 to obtain the luminance signal Y' and a color difference signal R-Y', and a scan converter 6 is used to generate the luminance signal Y' and the luminance signal Y' of one line before based on these signals, and they are supplied to a demodulator 7. Simultaneously, the output of the converter 6 is inputted to a matrix circuit 8, and this output and the output of the demodulator 7 are converted to R, G, and B signals, and they are displayed on a non-interlace monitor 9.

Title: Seedling planting machine
Inventor: OUCHI TAKEYUKI
IPC: A01C11/02
Filed: 1996-03-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the possibility that a sensor float moves up and down owing to variation in vehicle speed and the height of a seedling planting device from a mud surface becomes unstable to make the planting depth of seedlings unstable when the seedling planting device is elevated and lowered by the vertical movement of a sensor float. SOLUTION: A travel vehicle body 1 which moves forward by rotating its wheels 7 and 8 on a plowsole is provided with the seedling planting device 2 so that it is elevated by a driving device 3. The sensor float 43 is fitted to the seedling planting device 2 so that it slides on a mud surface while swinging around the lateral shaft 46 of the rear part. When the front end of the sensor float 43 moves up and down, the seedling planting device 2 is elevated and a controller performs output to a driving device 3 with the input from the sensor float 43 so that the seedling planting device 2 is held at constant height from the mud surface even if there is a shallow or a deepness on the plowsole.  The output of the controller is generated on the basis of a corrected value obtained by correcting the input from the sensor float 43 with a coefficient including the square of the vehicle speed of the travel vehicle body 1.

A molten metal is cast through the charging nozzles 10 disposed in the recesses 8 to both short sides of the sprue 4 as shown by C, to prevent the formation of a solidified shell on both short side surface sides of the sprue 4 and to throttle the molten metal to the thickness of a thin walled billet. The amt. of the molten metal to be charged is adjusted between said nozzles and a charging nozzle 5. The formation of the solidified shell along the short side surfaces of the funnel-shaped sprue is thus thoroughly prevented and the drawing of the billet by the metallic belts is made easy.

Title: Magnetic head
Inventor: TODA YASUSHI
IPC: G11B5/127
Filed: 1981-04-28
Abstract: PURPOSE:To obtain simple construction, excellent high frequency characteristics, low power consumption and multitrack easily, by constituting at least one of magnetic poles of a magnetic head consisting of a main magnetic pole and an auxiliary magnetic pole with a cylindrical permanent magnet. CONSTITUTION:The polarity of a permanent magnet cylindrical auxiliary magnetic pole 301 and the running direction of a recording medium are as shown in figure. A winding 302 is given at the tip of a main magnetic pole 101. The front side of a vertical recording layer 105 is taken as the S pole. With a current in the winding 302 zero, the magnetization is inverted. While a current flows to the winding 302 to the amount that the N pole is generated at the tip (a) of the main magnetic pole, the recording layer 105 remains the S pole because of no magnetization inversion. Thus, magnetic recording can be made in accordance with the signal current supplied to the winding 302. A magnetic recording medium 104 can smoothly be run with freely rotatable cylindrical shaped magnetic pole. The cylindrical shape inhibits fringe effect noise.

Title: Overcurrent protective circuit for transistor
IPC: H02H7/12
Filed: 1992-03-19
Abstract: PURPOSE:To provide an overcurrent protective circuit for transistor in which a transistor can be protected positively while eliminating a resistor for overcurrent detection. CONSTITUTION:A transistor Q1 for driving an external load is selected such that the base current Ib thereof at the time of turn ON will comes within a maximum rated collector current Ic (Ic>betaIb). When an overcurrent flows to the collector side of the transistor Q1 due to short circuit of the external load or wiring, the transistor Q1 is not saturated so long as the base current Ib is higher than the collector current Ic and thereby the collector-emitter voltage of the transistor Q1 increases. Consequently, current flow from a resistor R3 to the diode D side is interrupted and a current flows through a resistor R4 to the base side of a transistor Q2. Consequently, the transistor Q2 is turned ON and the base current Ib of the transistor Q1 is interrupted thus protecting the transistor Q1.

Abstract: PURPOSE:To allow the antenna to cope with a large sized antenna configuration and to allow a ununiform thermal distribution hardly to take place by providing a weight in a rear side direction of a tip of a rib via a span part and coupling a rotary drive mechanism to a center shaft. CONSTITUTION:A weight 5 for generating a centrifugal force is provided in the rear side direction of the tip of a rib 4 via span parts 4a, 4b and a rotary drive mechanism (motor) 10 is coupled with the center shaft 7.

Moreover, ununiform thermal distribution being a cause to thermal deformation hardly takes place by the drive. Thus, it is possible to realize a light weight satellite mount large sized antenna with less thermal deformation, multi-beam arrangement with a large electric field strength is attained, the ground station is economized and the effective utilization of frequencies or the like is attained.

Filed: 1986-03-24
Abstract: PURPOSE:To constitute a D/A converter with only resistances having the same value and to facilitate controlling the production process and designing the layout while keeping a high precision by using resistances having the same value in a symmetrical ladder type resistance ladder circuit and weighting a current conducted to them with a specific resistance ladder. CONSTITUTION:Currents conducted to ladder resistances R are weighted in accordance with a power series of 1/2 by base resistances R which make emitter potentials of transistors TRs Q1-Qn, which constitute current mirrors, different from one another by DELTAV. As the result, resistances having the same value can be used as the resistances of the ladder circuit. Currents may be weighted not by causing voltage drop by base resistances but by changing emitter areas.
