Title: Disturbing-wave eliminating antenna device
Inventor: FUJITA RIKUO
IPC: H01Q3/30
Filed: 1980-03-31
Abstract: PURPOSE:To receive a wave in the direction where maximum composite directivity can be obtained by adjusting the antenna direction so that a disturbing wave arrives in the horizontal direction with + or -90 deg. to the front surface direction of antenna directivity and then by arranging the antenna so that a desired wave is synthesized in phase. CONSTITUTION:So that a disturbing wave arrives at angles of + or -90 deg. to the front surface directions of two antennas 1 and 2, their antenna directions are adjusted and the both are placed at an interval in the disturbing wave direction. Then, the sensitivity of each antenna to the disturbing wave is zero, so that no disturbing wave output appears. Further, phase shifter 3 is interposed in the feeder of antenna 1 closer to the arrival direction of a desired wave so as to mix the desired radio wave by mixer 4 in phase.

IPC: B29D17/00
Filed: 1986-02-26
Abstract: PURPOSE:To enable the titled device to control generation of residual stress as low as possible, by a method wherein when the central part of a disk on the inside of an existing cavity is blanked by a punch, resisting force in the direction opposing to pressing force of the punch is applied to a sprue bushing at the time of a backward movement of the said sprue bushing. CONSTITUTION:When mirror surface plates 7, 47 on a stationary and movable sides close upon completing mold clamping, molten resin on the inside of a heating cylinder 18 is injected into a mold cavity. Although the central part of a molded disk is opened through blanking by a method wherein when injection is completed, a cylinder 32 is operated, a piston 33 is shifted leftward and a punch 50 is ejected leftward in this instance, a sprue bushing 12 begins a backward movement along with a forward movement of the punch 50. Along with the above matter a piston 61c is moved backward also, which results in flowing out of oil on the inside of a hydraulic cylinder 61 through an oil hole 63. As the oil flows in an oil tank 66 through an electromagnetic proportional control valve 69 resistance is generated and resisting force in the direction opposing to pressing force of the punch 50 is applied to the sprue bushing 12. This resisting force can adjust arbitrarily a preset value of the electromagnetic proportional pressure control valve 69 by varying the preset value.

Title: Vertical synchronizing separator circuit
Inventor: OKAJIMA MASAYUKI
IPC: H04N5/10
Filed: 1986-02-28
Abstract: PURPOSE:To prevent an erroneous detection with a simple constitution by giving a register reading a composite synchronizing signal by a clock which has a frequency twice a horizontal synchronizing signal and rises at the prescribed timing, a register which reads the output of the former register by said clock and a circuit which executes the OR operation of the output signals of both registers. CONSTITUTION:To an input terminal I2, a clock is given whose frequency is twice the horizontal synchronizing signal and whose pulse rise lies between two adjacent equalization pulses included in the composite synchronizing signal S1. A waveform illustration S1 shows the composite synchronizing signal inputted to the input terminal I1. The part excluded the vertical synchronizing signal and a noise pulse N lies between two horizontal synchronizing signals H. The noise pulse N is in the position of the rise of the clock S, so the output signal S3 of a register 1 becomes the waveform as illustrated and the output signal S4 of a register 2 becomes the waveform as illustrated. However, by executing the OR operation of the signals S3 and S4 in the OR gate circuit 3, the output signal S5 of the circuit 3 is always at a high level, so that the noise pulse N is not mistakenly detected as the vertical synchronizing signal.
