Title: Cardioid directional antenna rotatable in beam direction
Inventor: IKEDA JIYUNICHI
IPC: H01Q21/29
Filed: 1982-09-06
Abstract: PURPOSE:To electrically perform omnidirectional beam rotation without using any driving mechanism and, at the same time, to miniaturize the device, by using two 8-shaped directional antennas which are arranged at right angles to each other and one non-directional antenna. CONSTITUTION:A 90 deg.-phase shifter 13 is connected to one 8-shaped directional antenna 11 of two 8-shaped directional antennas 11 and 12 which are arranged at right angles to each other and output signals of the 8-shaped directional antennas 11 and 12 are combined at the same amplitude with a phase difference of 90 deg. at a combiner 14, and thus, a non-directional antenna is constituted. Furthermore, a non-directional antenna 15 having no phase directivity is provided and a variable phase shifter 16 is connected to the output of the antenna 15 and cardioid directivity is obtained by combining the output of the antenna 15 at a combiner 17 after the amplitude of the output is equalized to that of the output of the non-directional antenna containing the two 8-shaped directional antennas 11 and 12. When the phase shifted amount by the variable phase shifter 16 is changed, the maximum beam direction of this combined antenna can be rotated optionally.

Title: Effects device
Inventor: INOUE TOSHIHIRO
IPC: G10H1/057
Filed: 1988-06-23
Abstract: PURPOSE:To prevent clock noises from being generated by giving an attenuation envelope to a delay output signal before variation and giving a rising envelope to a signal after variation at the same time, and outputting their composite signal from a variable delay means. CONSTITUTION:A variation detecting circuit 34 detects the variation of the output data of a delay length setting part 29 and outputs an envelope indication signal according to the detection. For example, when the variation from delay length corresponding to a delay output signal D1 to delay length corresponding to a delay output signal D2 is detected, an attenuation envelope indication signal S1D for the signal D1 and a rising envelope indication signal S2A for the signal D2 are outputted. Thus, both signals which are given the envelopes are put together with contrary characteristics to obtain the output signal of the variable delay means. Consequently, even if the output signal corresponding to the delay length before the variation is out of phase with the output signal corresponding to the delay length after the variation, both signals are switched smoothly and the generation of clock noises is prevented.

Filed: 1977-12-22
Abstract: PURPOSE: To smooth and finish the inner surface of a socket with ease and good accuracy, by molding a tube from a resin material having a curing rate lower than the other part used forming the socket inner surface only.  
     CONSTITUTION: The band material 6 impregnated with a resin containing a hardener which will decompose at a relatively high temperature, etc. is wrapped around the the mandrel 1 and the inner layer 5 of the socket to form the inner surface layer. A filler is fed from the filler feeder 7 to the surface of the material 6 to form the intermediate layer. The band material 9 containing a hardener which will decompose at a relatively low temperature, etc. is wrapped around the intermediate layer to form the outer layer. The tubular material thus obtained is passed through the heating furnace 10 and cured without curing the inner surface 5 of the socket sufficiently.

Filed: 1979-11-29
Abstract: PURPOSE: To simplify an optional operation of the delay time as well as the constitution of a pyrotechnic time limiting device, by securing a flexible relative movement for both the delay line and the initiator to the time extending direction.  
     CONSTITUTION: The inserting part 13 of the initiator 16 is put into the hole 7 of the case 6 and then moved to a desired position. Then the ratchet detent 20 is hooked into the long groove 2 to extend in a spiral form. Thus the time delay line 9 of which one end is connected to the output powder 4 and the initiator 16 have a relative movement in the extending direction, and thus the relative position is decided. According to these relative positions, said line 9 has a contact with the fire path 18 of the initiator 16. As a result, the desired pyrotechnic time limit is selected in a simple way. At the same time, the constitution of the pyrotechnic time limiting device is simplified with a small-sized and light-weight structure.

Abstract: PURPOSE:To make it possible to open and close a gas passage by the predetermined displacement action of an operating shaft by a method wherein a means to control the displacement of a valve, which controls the opening and closing of a gas passage, is made by combining a guide cam with a rotary cam. CONSTITUTION:By pushing an operator 13 in an operating panel 12 so as to be nearly flush with the operating panel 12 under the state that the gas is turned off, a rotary cam 16 is pushed by the tip of a cam 15, which connects to the tip of a shaft 14 interlocking with the operator, so as to push a main rod 5 in order to open a safety valve 4 and a main valve 8. When a user removes his hand from the operator 13 after the ignition of a gas burner, the operator 13 projects far beyond the surface of the operating panel 12 and at the same time the shaft 14 is restored to its initial position by means of a spring A 17. Next, when the turning-off of the gas is intended, by pushing again the projected operator 13 in the panel and, after that, removing the hand of the user from the operator, the rotary cam 16 is pivoted so as to be restored to its initial position, resulting in letting the main valve 8 close the gas passage.
