Title: Portable headphone type audio system
Inventor: YAMAOKA TETSUYA
IPC: H03G3/32
Filed: 1987-04-02
Abstract: PURPOSE:To automatically adjust the sound volume in response to the noise level in the environment by converting the noise inputted from a microphone from AC to DC signal and changing the audio signal generated in the audio system in proportion to the noise signal level subjected to DC conversion. CONSTITUTION:The microphone 1 inputs the external noise at reproduction and a voice to be recorded at recording, and a switch section 2 switches the inputted voice by the microphone 1 to an AC-DC conversion section 4 at reproduction and the reproducing/recording section 3 at recording. Moreover, the voice inputted from the microphone 1 at reproduction is recorded by a reproducing/recording section 3 and the noise inputted from the microphone 1 is converted into a DC level signal proportional to the noise level by the AC/DC conversion section 4. Thus, even if a surrounding noise level is changed, the sound is listened always to a proper level automatically.

Abstract: PURPOSE:To leave the resist of a side etching part for an etching mask, and manufacture an HBT having a protecting layer in the depletion state in an outer base region, by spreading positive type resist, and exposing the whole surface to light without using a photo mask. CONSTITUTION:An emitter electrode 7 is formed on multilayer structure material for an HBT wherein a collector contact layer 2, a collector layer 3, a base layer 4, an emitter layer 5 and an emitter contact layer 6 are epitaxially grown on a semiinsulative GaAs substrate 1. An element isolation region 8 is formed by implanting hydrogen ions (H<+>), and a part of the layer 6 and a part of the layer 5 are selectively subjected to a first wet etching. In this process, a part of the layer 5 and a part of the layer 6 under the emitter electrode 7 are subjected to side etching. Positive type resist 9 is spread on the whole surface. When the whole surface is exposed to light without using a photo mask, only the resist of the side-etched part under the electrode 7 is not exposed. By development, the resist is left in the side-etched part and turns to a side wall 9A.

Title: Solid-state memory
Inventor: SUZUKI AKIHISA
IPC: G11B7/2433
Filed: 1986-04-10
Abstract: PURPOSE:To raise the information recording density by using local residual polarization due to the pyroelectric effect as information recording and reading out recorded information by the change of the refractive index due to this residual polarization. CONSTITUTION:When a laser bema 18 is locally projected in a spot size, it is made incident on the inside of a recording part 12 through a protective layer 16 and is absorbed in the stage of repeated reflection on lower and upper boundary faces of the recording paper 12, and therefore, the recording part 12 is momently heated. When the recording part 12 is locally heated in this manner, an electric charge is generated by the pyroelectric effect because the recording part 12 consists of a dielectric having the pyroelectric effect; and when the recording part 12 is cooled after heating is stopped, residual polarization due to the electric charge is locally generated in the recording part 12, and information is recorded by this local residual polarization. Recorded information is optically detected by the local change of the refractive index caused by the residual polarization based on an electrooptic effect.

Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To reduce the difference in longitudinal scanning areas at both right and left ends of a measuring area in a reflection measuring device using a polygon mirror, whose respective plane-inclining angles are different. SOLUTION: In a reflection measuring device 1, a semiconductor laser diode 21 and a collimator lens 23 are arranged at the rear upper part of a polygon mirror 31, wherein the inclining angles of the respective mirror planes are different. The infrared pulse light from the semiconductor laser diode 21 is reflected to slant backward by a mirror 24 arranged at the upper part of the front of the polygon mirror 31 and applied on the mirror plane of the polygon mirror 31. The reflected light from a body present in a measuring area is condensed with a light receiving lens 50 and applied into a photodetector 60. Thus, the interval between the scanning lines reflected from the respective mirror planes becomes constant, and the gap is not generated in the measuring area.

When a light source is installed below the picture element, the light made incident from the lower side of the transparent turning disk 51 transmits a polarizer 52 and is radiated upward.  A quantity of light transmitting the polarizer 52 is regulated by a rotation angle of the polarizer 52.
