Title: Isolator and modem device using the same
Inventor: NAMETAKE MASATAKE
IPC: H01L21/822
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To reduce the size of an isolator function by providing a capacitive insulating means, which transmits signals between a primary-side circuit and a secondary-side circuit and insulates and separates the primary- and secondary- side circuits from each other on a semiconductor substrate. SOLUTION: A dielectric breakdown voltage between a primary side and a secondary side is ensured by means of an interlayer insulating film containing an SOI embedded oxide film 902, trench insulating films 921-925, and a LOCOS 904. In addition, the dielectric breakdown voltage of a capacitor which makes the signal transmission between the primary side and secondary side is ensured by an interlayer insulating film containing the LOCOS 904 between a diffused layer and a metal layer. Since the isolation and separation of the primary side and secondary side from each other can be made on the same semiconductor substrate, and in addition, the capacitor having a high dielectric breakdown voltage can be formed between the primary side and secondary side, an isolator can be made in a monolithic one.  In addition, since the capacitor between the primary side and secondary side is constituted of the interlayer film, a desired capacitance value can be obtained regardless of the thickness of the SOI silicon film.

Title: Infrared-ray detecting circuit
Inventor: TANEI FUMIO
IPC: G08B13/191
Filed: 1982-03-26
Abstract: PURPOSE:To detect whether a man exists or not in an area, without an error, by discriminating a time when a level of a pyroelectricity detecting signal continues a higher value than prescribed, controlling an integral period of the pyroelectricity detecting signal, and discriminating an integral value exceeding the prescribed value. CONSTITUTION:A pyroelectricity detecting signal having no drift of infrared-rays by a man in a prescribed area by a differentially responding pyroelectricity detector 11 for forming an infrared-ray detector is impressed to the first discriminator 12, a continuous time by which an absolute value exceeds a prescribed value is discriminated, and an integral period of an integrator 13 for integrating the pyroelectricity detecting signal is controlled. Subsequently, when it is decided that an integral output of the integrator 13, which becomes constant irrespective of a passing speed of a man passing through in the area exceeds a prescribed value, by the first discriminator 14, it is discriminated that a man exists in the area. Accordingly, it is unnecessary to lower a prescribed threshold level of the discriminator, and whether a man exists in the area or not can be detected without causing a malfunction by a signal due to movement of a man.

Title: Switching circuit for wavelength multiplexed light
Inventor: KOMATSU YOSHIRO
IPC: H04Q3/52
Filed: 1986-03-06
Abstract: PURPOSE:To obtain a high function switching circuit for wavelength multiplexed light capable of multiple address communication or the like by a simple constitution consisting of an optical branching circuit, a variable optical wavelength filter, and a wavelength converting circuit. CONSTITUTION:A wavelength multiplex signal propagated in an input-side optical waveguide 101 is branched to N-number of signals by an optical branching circuit 102. Branched wavelength multiplexed signals are sent to variable optical wavelength filters 103-1-6 having variable pass wavelengths, and only the optical signal having a predetermined wavelength passes through each of these filters by a control signal. Spatially separated wavelength signals are converted to optical signals having specific wavelengths by wavelength converting circuits 107-110, and emitted beams of light have wavelengths multiplexed again by an optical multiplexing circuit 111 and are led to an output-side optical waveguide 112. Since beams of light which pass variable optical wavelength filters 103-106 are converted to optical signals having specific wavelengths by wavelength converting circuits 107-110, optical signal conversion is possible if wavelengths of beams of light passing variable optical wavelength filters 103-106 are controlled.

Title: Paper feed controlling method for copying machine
Inventor: SAKURAI TETSUO
IPC: B65H3/06
Filed: 1986-03-10
Abstract: PURPOSE:To make stable paper feed and timing control performable, by stopping drive at the upstream side of a roller if duration that paper is stopped by a resist roller exceeds the specified value, and making a loose quantity and a paper interval so as to be controlled. CONSTITUTION:When an end of the n-th transfer paper 19 is detected by a resist sensor 23 on this side of a resist roller pair 22, each rotation of these paired rollers 22 is stopped, but since the paper is continuously fed by a feed roller pair 21 even if the end comes into collision with the paired rollers 22, a loose part A is formed in a spot short of these paired rollers 22. This loose quantity is allowable up to a range of 30mm but if it becomes more than this range, each stop time of these paired rollers 22 is counted up, and when reaching the value equivalent to a looseness of 30mm, a driving clutch 25 of the whole paper feed part is turned off, whereby such a possibility that the loose part A is bent, bitten by these paired rollers 22, or bent in a Z-type is prevented from occurring. Thus, a paper interval is almost equal to an original circulating interval, whereby control can be done at the same timing so that paper feeding becomes easy, and even if the stop time comes longer, looseness will not grow larger, thus feed control is stably performable.

Title: Film composition
Inventor: SAKAKIBARA TOSHIYUKI
IPC: C09K23/14
Filed: 1996-03-07
Abstract: PROBLEM TO BE SOLVED: To make a film expandable and its structure hardly destructible even under compression by setting the minimum surface area of a film composition when a film pressure is changed by forming a monomolecular film on a water surface to be at least a prescribed percentage or higher of the maximum surface area of the film composition. SOLUTION: If a matter of a structure such as having a skeletal part and a side chain (film stabilizing matter) like styrol fatty acid ester is added to a film forming matter, the film stabilizing matter works as a cushion in the film and eases a compressing force to form a hardly destructible film. In addition, if the film forming matter and the film stabilizing matter are used for an emulsion, a cosmetic or a liposome, the film shows an improved stability over time and a soft touch to the skin. That is, when a film composition forms a monomolecular film on the water surface to change a film pressure, the minimum surface area of the film composition will be equivalent to 10% or higher the maximum surface area of the film composition. The emulsion contains a stabilized film obtained from this film forming composition.

Filed: 1997-02-19
Abstract: PROBLEM TO BE SOLVED: To prevent electrostatic destruction of a magneto-resistance sensor element (MR element) by arranging a slider fixedly with the MR element connected between one lead or pad and the other lead or pad and a resistor arranged in parallel. SOLUTION: The leads 38 and 40 are connected to both end parts of the MR element 36, and the pads 60 and 62 are connected to end parts of the leads 38 and 40 respectively. The resistor 74 is connected between the pads 60 and 62. The resistor 74 is formed of the same material as the MR element 36. At the time of forming the MR element 36, this is formed to be connected with the end parts of the leads 38 and 40 at the same time. The resistor 74 is formed in a kudzu-like folding pattern. Consequently, when one pad is charged with static electricity, an electric charge is distributed through the resistor 74 to the other pad to prevent generation of a large potential difference between both ends of the pads 60 and 62, so as to prevent electrostatic destruction of the MR element 36.  A resistance value of the resistor 74 is set to a desired value by the number of folding times of the kudzu-like folding pattern.
