IPC: H03G3/00
Filed: 1987-07-30
Abstract: PURPOSE:To prevent an excess peak signal from being applied to a speaker by restoring the sound level to the original sound volume setting level gradually at the re-operation of a mute operation switch. CONSTITUTION:An input signal is fed to a speaker 3 via an electronic volume circuit 1 and an amplifier circuit 2. In operating a mute operation switch S3, the sound volume setting level at that point is stored in a memory in a control circuit 4 and the sound volume setting level of the electronic volume circuit 1 is set to a zero level by the control output of the control circuit 4. In operating the mute operation switch S3 again, the sound volume level of -50dB is, for example, at first, set by the control output of the control circuit 4, and the sound volume setting level is controlled to be increased gradually till the original sound volume setting level at a prescribed step. Thus, the leading of the excess output is not applied to the speaker at the restoration from the mute state thereby preventing the speaker from the destroyed.

IPC: G06F11/22
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To shorten a supply time of an address signal from a pattern generator to a defect analysis memory in a memory test device. SOLUTION: An address generating section 110 incorporated in a pattern generator 60 outputs a first address signal 62 and a second address signal 64 to a defect analysis memory 20 in two systems.

Filed: 1996-07-03
Abstract: PROBLEM TO BE SOLVED: To provide an ohmic electrode and its forming method which has a low contact resistivity with an n-type nitrogen III-V compound semiconductor. SOLUTION: When an ohmic electrode is formed on an n-type GaN layer 1 having a low carrier density, after forming an Al-Si alloy film or an Al/Si multi-layer film 2 on the n-type GaN layer 1, n<+> -type layer 3 having a high carrier density is formed by diffusing Si in the Al-Si alloy film or the Al/Si multi-layer film 2 into the n-type GaN layer 1 by means of thermal processing at temperature of 500 to 600 deg.C. An Au-Si alloy film or an Au/Si multi-layer film may be used instead of the Al-Si alloy film or the Al/Si multi-layer film 2.

Filed: 1984-09-14
Abstract: PURPOSE:To improve the coupling efficiency of guided light in the input and the output to improve the efficiency of optical deflection by making the density of protrons near a substrate surface in an optical function part higher than that in optical coupling parts. CONSTITUTION:Parallel light 8 from an He-Ne laser is condensed on a polished end face 3 of an optical waveguide in the thickness direction of the optical waveguide by a cylindrical lens 5 and is coupled into the optical waveguide. A guided light 9 coupled from the end face of the optical waveguide is diffracted by a surface acoustic wave 10 generated by applying an RF power to a comb- shaped electrode 7, and the diffracted light is discharged from an end face 4 of the optical waveguide and becomes a parallel light by a cylindrical lens 6. Since the optical waveguide 2 is provided with a high-density protron layer 20 in the area of the interaction between the surface acoustic wave 10 and the guided light 9 and the density of protrons near the substrate surface in the optical function part is higher than that in optical coupling parts, the electric field intensity distribution of the guided light is pulled up to the substrate surface side in this area, and the efficiency of diffraction of the guided light due to the surface acoustic wave is made high.

Abstract: PROBLEM TO BE SOLVED: To prevent a transfer sheet from being soiled at its leading end, rear end, side edges, and back during image formation, by separating a transfer entrance guide plate into pieces in the axial direction of a drum-like photoreceptor and insulating them from each other. SOLUTION: A transfer entrance guide plate is disposed such that it is separated into pieces in the axial direction of a drum-like photoreceptor and they are insulated from each other. That is, the transfer entrance guide plate is separated into the pieces in the axial direction of the photoreceptor, (in this example, three metal plates, 46A, 46B, and 46C) and they are connected to each other with a resin plate 47, as an insulator, and electrically completely separated from each other. In this state, in the case the width of 46B has a dimension covering the width of a B4-size transfer sheet for example, the parts of 46A and 46C adjacent thereto cannot accumulate charges through the transfer sheet when the B4-size transfer sheet is passed on 46B.  Therefore, even when an A3-size transfer sheet for example is next passed, both side edges of the transfer sheet and back of the part are prevented from being soiled with toner.

Abstract: PURPOSE:To easily deepen the depth of an object side without reducing NA or dropping magnification, by moving a little one of a pair of objective lenses to an image side along an optical axis, and shifting a focal position of an optical system. CONSTITUTION:The best points on an object, which are coupling with imates 5, 5', near points being nearest objective lenses 2, 2' of the depth of an object side, and far points being farthest are denoted as P0, P'0, and P1, P'1, and P2, P'2, respectively, by which the depth of an object is shown by A. When one objective lens, for instance, 2' is moved along an optical axis X', and is moved to a position (a position of a dotted line) where a far point P''2 does not cross an intersection point P0, a focal position is moves to P'0, and also object side depth A' becomes deep. In this case, blur of left and right images and a difference of magnification do not become a problem in reality within a range of the object side depth. Accordingly, the object depth becomes deep without reducing NA or dropping magnification.
