Title: Transmitter with noise preventing circuit
Inventor: FUJISAWA SHINICHI
IPC: H04B1/04
Filed: 1987-06-24
Abstract: PURPOSE: To prevent occurrence of noises when a power source is actuated, by starting transmission after occurrence of noises from a digital phase comparator is terminated when the power source is actuated.  
     CONSTITUTION: Since the control voltage of an automatic phase controlling circuit (APC) becomes abnormal for a fixed time after the power supply is turned on, an APC voltage discriminating circuit 1 sends a logic signal of '0' to a delay circuit 2. Upon inputting the logic signal of '0', the delay circuit 2 immediately controls a switch 3 to open. When the APC controlling voltage becomes a normal value, the APC voltage discriminating circuit 1 generates a logic signal of '1' and the delay circuit 2 controls the switch 3 to turn on after a delay time which is required for locking the transmitting output frequency elapses. Therefore, even when the oscillation frequency of a voltage controlled oscillator (VCO) rises from a point far from the center, the transmitter generating no noise is obtained.

Title: Method for coloring granular fertilizer material
Inventor: SUGAWARA HARUSHIGE
IPC: C05G3/00
Filed: 1987-06-24
Abstract: PURPOSE: To improve the colorability and abrasion resistance of a granular fertilizer and to reduce the coloring cost by forming an aq. solution of a condensation product of urea and formaldehyde, that contains an added colorant, and treating a granular fertilizer material with this aq. solution.  
     CONSTITUTION: This method comprises forming a condensation product of urea and formaldehyde (UF condensation product), that contains a colorant, as an aq. solution and treating a granular fertilizer material in this aq. solution to form a very thin coating layer on the surface of each of the fertilizer material granules. At this time, the colored coating layer on each of the granules can simply be formed e.g. by heating the granular fertilizer material beforehand, then spraying the surface of each of the fertilizer material granules with the UF condensation product aq. solution and rotating the sprayed granules for a specified time with a rotary drum. Since this coating layer is firmly stuck to the surface of each of the fertilizer material granules, peeling of the coating film from the granule can be prevented from occurring. Further, since such a very thin coating layer is sufficient to fulfill the purpose, the colorability and abrasion resistance of a granular fertilizer can be improved and the coloring cost can be reduced.

IPC: F01L1/26
Filed: 1989-06-20
Abstract: PURPOSE:To improve intake/exhaust efficiency more by arranging a valve for allowing a relatively large flow out of a plurality of valves, toward the center of respective cylinder line directions. CONSTITUTION:Two valves 12a, 12b are operated in opening and closing motion in compliance with head curve lines which are different from each other, the valve 12b arranged on the cylinder line direction center side of each combustion chamber 13 is driven in compliance with the head curve line of a wide opening angle and a high head relatively, while the valve 12a arranged outside is driven in compliance with the head curve line of a narrow opening angle and a low head relatively. Thus, a clear difference is qcuerated in a passing flow rate by differentiating the heads and the opening angles of two valves 12a, 12b from each other. The improvement of relative intake/exhaust efficiency is promoted more by arranging the valve 12b of the wide opening angle and the high head causing a larger flow rate, on the side of the cylinder line direction center having a smaller flow passage resistance.
