Title: Sound signal processor
Inventor: TAKAHASHI MASAYUKI
IPC: H03G1/00
Filed: 1982-04-07
Abstract: PURPOSE:To control the starting level of compression and expansion, by displaying both the level of a sound signal and the level of a DC control signal obtained from the sound signal. CONSTITUTION:The signal obtained by a reproducing head 1 is amplified by a reproducing system containing a noise reducing circuit of a Dolby system. A converting circuit 10 gives the wave detection to a sound signal to obtain a DC signal. A level detecting circuit 11 produces a control signal when the voltage of the DC signal is higher than a certain level. The detecting level can be changed by a resistor 16 and at the same time the level of the control signal is displayed at a display 28. The control signal controls the gain of an amplifier 8. The signal is expanded when it is reproduced, and the expanding ratio is decided by a voltage dividing circuit 23 consisting of a resistance. Both states of expansion and compression are shown through level displays 27 and 28. Thus a change is facilitated for the starting level or the ratio.

Filed: 1988-03-10
Abstract: PURPOSE:To accurately evaluate an objective lens having no positioning reference, by correcting the shift between the optical axis of the light incident to a lens to be inspected and the optical axis of the lens to be inspected. CONSTITUTION:A revolver 18 is rotated to oppose an objective lens 18a to a lens 15 to be inspected. The beam emitted from semiconductor laser 1 is condensed by a condensing lens 10 to pass through a pinhole 11 and supplied to a collimation lens 3 to be brought to parallel beam. A part of this beam transmits through the semi-reflecting surface 2a through the semi-reflecting surface 2a of a beam splitter 2 to be incident to a lens 15. This incident beam is condensed by the lens 15 to form a fine spot on the upper surface of a dummy disc 17 and said spot is magnified by a lens 18a to be projected on a television camera 19. Herein, when there is coma aberration, the optical axis of the lens 15 is inclined with respect to that of inspection beam. At this time, the angle of a goniometric stage 14a is adjusted while the pattern projected on the camera 19 is observed to correct the fall of the optical axis of the lens 15.

Title: Variable resistance element and semiconductor device using same
Inventor: FUNAKI TETSUJI
IPC: H01L27/04
Filed: 1986-03-18
Abstract: PURPOSE:To vary the resistance value of an impurity region by forming the opposite conductivity type impurity region in one conductivity type semiconductor substrate, and forming metal electrodes through an insulating film on the impurity region, and applying a variable voltage to the metal electrodes. CONSTITUTION:A variable voltage is applied to metal electrodes 12 formed through an insulating film 13 on a P-type impurity region 11 to vary a resistance value between connecting terminals A, B. More particularly, when a positive voltage is applied to a control input C, the electrode 12 becomes positive, electrons are collected on the surface of the region 11 directly under the film 13, the effective sectional area of the region 11 is reduced to increase a resistance value between connecting terminals A, B. When a negative voltage is, on the contrary, applied to the control input C, the electrode 12 becomes negative, holes are gathered on the surface of the region 11 directly under the film 13, a current tends to readily flow in a channel with the holes. Thus, the resistance values between the connecting terminals A and B is reduced.
