Title: Optical module, transmitter, receiver, optical switch, light communication apparatus, add-drop multiplexer, and manufacture of optical module
Inventor: IDO TATSUMI
IPC: H04B10/077
Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To form an optical module being higher-performance and lower-cost than one heretofore in use by providing a method and construction which make it possible to realize height adjustment for the core layers of a polymer waveguide and a semiconductor device with less characteristic degradation and by fewer manufacturing processes. SOLUTION: An optical integrated circuit or waveguide having a lower clad layer, a core layer, and an upper clad layer is formed on a silicon substrate having a silicon oxide film, and a semiconductor optical element is mounted on an electrode formed on a silicon oxide film at its part excluding the polymer optical waveguide. Besides, the thickness of the lower clad layer is set to 3-9 μm, and the thickness of the core layer is to 5-8 μm to thin the lower clad layer and make the height of the center of the core layer 5-12 μm so as to coincide the center height of the core layer of an optical semiconductor with that of the polymer waveguide.  Accordingly, it is all right if d and ncorc are set so that a relation of d>λ/(2π.ncorc2-nsio22)1/2) may be satisfied among the thickness (d) of an oxide film, its refractive index (nsio2), the refractive index (ncorc) of the core layer, and the wavelength (λ) of light which propagates through the optical waveguide.

Title: Automatically and simultaneously adjusting device for coating amount of plurality of samples for electrophoresis
Inventor: NAKAZATO TOKITSUGU
IPC: G01N27/447
Filed: 1992-08-31
Abstract: PURPOSE:To individually adjust the numbers of applying times of samples to substrate thin films by mounting a magnetic material on each chip of a sample coating section and controlling the vertical movement of each chip by actuating each electromagnet. CONSTITUTION:A plurality of chips 38 is fitted to a sample coating section 22 in vertically movable states. A magnetic material 39 is mounted on each chip 38 and electromagnets 40 are fixed to the parts of the main body of the section 22 at positions facing the magnetic is 39. When one of the magnets 40 are excited, the magnet 40 attracts its corresponding magnetic material 39 and fixes the chip 38 fitted with the material in a vertically movable state. When one of the magnets 40 is not excited, its corresponding chip 38 is extruded downward. In other words, the downward protrusion of each chip 38 can be controlled by applying a voltage across its corresponding magnet 40. For a sample which is applied one time only, for example, an electric current is made to flow to one of the magnets 40 in accordance with an instruction from a computer and the magnetic material 39 on the corresponding chip 38 is attracted to the magnet 40, but the other chips 38 corresponding to the nonexcited magnets 40 are maintained in downward positions. In such a state, the section 22 comes into contact with a substrate thin film 5 and the chips 38 in the downward positions apply the sample to the surface of the thin film 5.

Title: Inspection apparatus of logical circuit
Inventor: SUZUKI SHUSUKE
IPC: G06F17/50
Filed: 1988-09-19
Abstract: PURPOSE:To perform inspection at a high speed by a method wherein the output values between a plurality of inspection circuits are compared and, when non- coincidence is generated, a circuit to be inspected having a minority output value is confirmed to be inferior to judge a logical circuit. CONSTITUTION:In judging the quality of each of circuits 20-22 to be inspected, the output expected value calculated by a trouble simulation control part 13 and the output value of the circuit to be inspected having the minority output value shown by a test number 1 are compared by an output value comparator 12 and, when non-coincidence is generated, the circuit to be inspected having a majority output value is judged to be an inferior circuit and data of a non- coincidence logical circuit ratio and a non-coincidence logical circuit number are altered to the data of the circuit to be inspected having the majority output value. Since a logical circuit number has '1' different from other output value in a test number 2, a logical circuit number (n) is judged to be inferior because said number has '0' in a test number (n). Further, it is checked whether a non-coincidence dictionary 14 is formed and, when there is no non-coincidence, all of the circuits 20-22 to be inspected are regarded as a good product.

IPC: H04L27/22
Filed: 1991-09-12
Abstract: PURPOSE:To execute correct acquisition of synchronism even when an initial frequency error is large by utilizing the frequency discrimination action so as to suppress a frequency error through the automatic frequency control. CONSTITUTION:When a frequency error is large at the time of the acquisition and even if the phase error detection of a complex multiplier 9 is not worked well, a frequency discrimination signal is obtained by a output signal of a complex multiplier 14.

When the frequency error is decreased, the phase error detection by the complex multiplier 9 is started to operate the phase locked loop. When a frequency of a reception signal is changed during the operation, a frequency discrimination signal appears again at an output of the complex multiplier 14, the automatic frequency control is operated to reduce the frequency error thereby establishing the loop synchronization state again.

Title: Camera
Inventor: YAMAZAKI TATSUYA
IPC: G02B7/36
Filed: 1992-08-07
Abstract: PURPOSE:To stabilize automatic focusing by changing the extracting area of a sharpness signal in a prescribed period. CONSTITUTION:At the time of focusing under zooming, a count value C is incremented. When the value C is any even number, a distance measuring frame is made small, the sharpness signal fetched by a small distance measuring frame previously is defined as a previous value, and the sharpness signal extracted from a distance measuring frame this time is defined as the this-time value of a small distance measuring frame signal. The distance measuring frame is changed by supplying a control signal from a microcomputer 113 through a signal line 134 to a gate circuit 111. The sharpness signal fetched by a large distance measuring frame previously is defined as the previous value, and the sharpness signal extracted from the distance measuring frame this time is defined as this-time value of a large distance measuring frame. When it is discriminated that the previous value and this time value of the small distance measuring frame signal are almost equal, focusing is judged. When the this-time value is considerably changed from the previous value, the this-time value of the small distance measuring frame signal is compared with that of the large distance measuring frame signal and when they are almost equal, it is judged the object is moved or the object gets out of the small distance measuring frame by panning the camera. Thus, the stability of automatic focusing is improved.
