Abstract: PURPOSE:To obtain an optical modulator which operates at a low voltage and has good modulation efficiency by making the refractive index of a buffer layer on a P-N junction surface side higher than that of any other part in a P-N junction type modulator which has two buffer layers across an optical waveguide. CONSTITUTION:A buffer layer 6 of N-Ga0.8Al0.2As, a light guide 2 of N<->-GaAs, a buffer layer 7 of P<+>-Ga0.9Al0.1As, and a low-resistance layer 8 of P-GaAs are formed on an n<+>-GaAs substrate 1 by a liquid-layer epitaxial method in thickness of 1, 2, 1, and 0.2mum, and AuGeNi electrodes 4 and 5 for ohmic contacting are vapor-deposited on the P-GaAs low-resistance layer 8 and under the substrate 1. When the refractive indexes n1, n2, and n3 of the light guide layer 2 and buffer layers 6, 7 are so set that n2<n3<n1, the light guide 2 meets requirements of a longitudinal single mode to 1.15mum light and a 13dB degree of modulation is obtained at 9V by applying a forward bias between the electrodes 4 and 5.

Abstract: PURPOSE:To provide a residual amount detecting device where the residual amount of the sheet to be unwound as a feed roll is rotated is correctly measured and displayed, the constitution of parts is simple, and the arrangement space can be suppressed minimum. CONSTITUTION:A photosensor 57 detects the rotational angle of a feed roll 24, and a rotary encoder 56 detects the unwound amount of the ink ribbon which is unwound as the feed roll 24 is rotated.

In addition, the CPU compares the computed diameter (r) with the set value r 1, and if (r) is not greater than r1, the diameter is outputted in a residual amount display part, which displays that the residual amount of the ink ribbon is small.

Title: Air-permeable adhesive tape and its production
Inventor: SUGITA KOICHI
IPC: C09J7/02
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To obtain an air-permeable adhesive tape, especially one wound in a roll, which undergoes no or little long-term deterioration in air permeability by forming a pressure-sensitive adhesive layer and a porous base or an air- permeable base on a release sheet in the given order and forming air permeation pores containing non-hollow elastic microbeads in the pressure-sensitive adhesive layer. SOLUTION: As the pressure-sensitive adhesive used to constitute the pressure- sensitive adhesive layer a natural rubber, synthetic rubber or acrylic type one is used. The pressure-sensitive adhesive layer has air permeability, and part or all of its air permeation pores contain non-hollow elastic microbeads to an extent that its permeability is not substantially hampered.  The process for producing the air-permeable adhesive tape consists of adding an air permeation agent and optionally a crosslinking agent to a solution of a pressure-sensitive adhesive, uniformly dispersing non-hollow elastic microbeads in the formed uniform dispersion system, applying this dispersion to a release sheet, drying the sheet to form a pressure-sensitive adhesive layer having air permeation pores containing the non-hollow elastic microbeads and laminating the pressure- sensitive adhesive layer with a porous base or an air-permeable base.

Title: Method and device for detecting positional correlation of radiation
Inventor: HORUSUTO SHIYUMITSUTOOBETSUKIN
IPC: G01T1/28
Filed: 1995-08-23
Abstract: PROBLEM TO BE SOLVED: To enhance reliability in the determination of electronic position by accumulating the electron avalanche in the anode side vacuum of a detector and reading out the charges capacitively, as image charges, by a resistive anode means for positioning the charges on the outside of the vacuum. SOLUTION: A photoelectron conversion layer 4, the chevron plate system 3 in a multichannel electron multiplier, and a high resistance anode layer 1 are introduced into high vacuum 7. An anode structure 2 for reading out the position of electron is disposed on the rear of an opposing substrate 6. Positional information of incident radiation quantum is transmitted capacitively from the substrate 6 onto a low resistance anode structure 2 after multiplication of charges. The positional information can be transmitted because the charge collecting layer in the vacuum serves as a high resistance anode layer. A charge avalanche 8 passes through the substrate 6 and coupled capacitively to generate image charges on the anode structure 2 on the opposite side.  Since inner resistance at two anode layers 1, 2 is employed, high resolution is attained through the structures corresponding each other and the spatial resolution is enhanced through capacitive isolation.

Title: Deflection measuring structure for rotating circular cylinder
Inventor: OKI JUNICHI
IPC: G01B11/27
Filed: 1993-08-05
Abstract: PURPOSE:To accurately measure a run-out amount occurring due to an external force or the like, regarding a circular cylinder rotating about an axial center with one end having a journalled structure. CONSTITUTION:Detecting light is emitted toward a right circular cone hole 4 formed to have internal mirror surface and coaxially provided at the edge of a circular cylinder 1, so that the light is reflected in the hole 4 at least twice and, then, emitted externally. The reflective light is received, so as to allow the detection of a deflection from a reference position and, then, the deflection of the rotating circular cylinder 1 is found, depending upon the deflection of the reflective light, thereby enabling the run-out amount of the cylinder 1 to be easily detected. In this case, a deflection at a light receiving position becomes twice the radial deflection of the cylinder 1, due to the reflection of the light at least twice within the hole 4. Thus, the deflection can be detected with accuracy two-fold as high as the case of simple light reflection, thereby improving detecting accuracy.

Title: Semiconductor integrated circuit device
Inventor: SAITO SEIICHI
IPC: H01L23/482
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To obtain the distance between unit MOSFET elements by allowing an electrode that opposes wiring out of at least four electrodes which are arranged in a lattice shape at the minimum distance from the wiring and providing a side, that is in parallel with the extension direction of wiring. SOLUTION: With the shape of source electrodes 14 and 15, a side that faces an oblique wiring 18, for example, having an angle of 45 degrees is inclined at 45 degrees in parallel with the wiring 18. Therefore, a margin is generated at a gap 25 between the source electrodes 14 and 15 and the oblique wiring 18, and at least the minimum allowed distance can be secured, even if a gap 26 between the source electrodes 14 and 15 and drain electrodes 16 and 17 is reduced. As a result, the gap between unit MOSFET elements can be set narrow and reducing the area of an entire output part. In this manner, the distance between an electrode pattern and the side of an oblique wiring pattern corresponding to it can be reduced by the amount where the corner of the electrode pattern is cut, hence narrowing the distance between the unit MOSFET elements.

Abstract: PROBLEM TO BE SOLVED: To easily control the effective recording track width on a recording medium by a thin film magnetic head by identifying the extending of the lowest surface of an upper core layer to both external sides in the track width direction from the upper most surface of an upper layer of lower core layer working also as an upper shielding layer. SOLUTION: The lowest surface of an upper core layer 11 of an induction type head is extended to both external sides of track width direction than the upper most surface of an upper layer 31 of the lower core layer also working as an upper shield layer in the area opposed to a recording medium. Here, the extending (D, E) of the lowest surface of the upper core layer 11 in both external sides in the track width direction from the upper most surface of the upper layer 31 of the lower core layer also working as the upper shield layer is set to about 1.06 times or more the thickness (G) of a gap layer at least in one extending (D or E). Thereby, the extending of at least one effective recording track width becomes constant and allowable range of size error and alignment error of a thin film layer having effect on change of effective recording track can be widened.
