Title: Audio image positioner
Inventor: TAKADA AKIRA
IPC: H04S5/00
Filed: 1978-11-01
Abstract: PURPOSE: To enable to fit the audio image by monoral audio signal from a plurality of speakers to arbitrary direction, by the interlocking control of the control of delay time and the control of audio volume with a given relation.  
     CONSTITUTION: As the frequency of the clock generator C is increased, the delay time of audio signal passing through the delay element D is shorter, and the audio signal level obtained with the output terminal Oa with the voltage controlled amplifier A controlled with the voltage converted with the clock signal simultaneously is increased. Further, on the contrary, when frequency is lowered, the delay time is longer and the output audio signal level is smaller. Accordingly, by controlling the variable resistor VR 1  or VR 2  for the sliders L 1  or L 2 , between the output signals Sa and Sc and the output signals Sb and Sd, the phase delay and the magnitude of the audio level can reversely be changed. As a result, when control is made by using the controller controllable the two variable resistors, the audio image can be fixed to arbitrary direction.

Inventor: KOBAYASHI KENZOU
IPC: G02B6/38
Filed: 1979-10-22
Abstract: PURPOSE:To improve workability by enabling insulation sheaths to be formed simultaneously on plural core units. CONSTITUTION:Plural core units 1a are set to a sheath forming head 16 consisting of plural unit through-holes 18 penetrated respectively separately and plural dies 20 aligned on the outlet side of the through-holes 18.

Subsequently, a laser switch 34 is operated to radiate a laser beam. As a result, when the virtual line Q coincides with the reference line P, the laser beam reaches the target point M so that it is confirmed that the user's judgment is correct.
