  • Patent number: 10640313
    Abstract: An image forming apparatus includes a feeding member, a conveying member, and a detecting unit. The feeding member feeds a recording material stacked on a stacking unit. The conveying member convey the fed recording material. The detecting unit detect the conveyed recording material. Where the recording material is a first type, the feeding member feeds the stacked recording material at a first speed, and the conveying member changes the first speed to a second speed that is faster than the first speed before the detecting unit detects the recording material. Where the recording material is a second type that is different from the first type, the feeding member feeds the stacked recording material a third speed that is different from the first speed, and the conveying member changes the third speed to a fourth speed that is different from the third speed after the detecting unit detects the recording material.

  • Patent number: 10620098
    Abstract: An apparatus and methods for testing components under force is described herein. The apparatus comprises cap bolts that may be tightened to exert a measurable, constant force upon a lever arm that rotates about a fulcrum. The lever arm pushes down upon a push rod, to exert a force upon a test piece in an insertion well, which may be filled with fluid. The fulcrum may be positioned, such that the force from the cap bolt gives a magnifying, or a diluting force, upon the push rod.

  • Patent number: 10591398
    Abstract: A soot sensing system includes a soot sensor having a first element, and circuitry to an amount of soot accumulated on the element and to control heating of the element in response to the soot accumulation. An electrostatic repelling voltage (ERV) may be applied to a sensor/heater element(s) during a contamination prevention mode (CPM) to repel ash and reduce contamination of the sensor. A pulsed heating voltage (PHV) may be applied to the elements during the CPM and a pulsed ERV may be applied to the elements during the “off” period of the PHV. All voltage to the elements may be turned off during the CPM and the elements may be floating/ground. A PHV may be applied to the elements during the CPM and no voltage may be applied to the elements during the “off” period of the PHV. A heating voltage may be applied to the elements during a CPM corresponding to a cold start.

  • Patent number: 10591452
    Abstract: A gas chromatograph is provided which is capable of effectively reducing the amount consumed of a carrier gas, reducing the time and effort required for an operator to manually set parameters, and preventing damages to a column and a detector due to a setting mistake. In a case where a stop operation for the power supply of the gas chromatograph is performed (Yes in step S101), the flow rate of a carrier gas to be supplied to a sample vaporization chamber is decreased and the temperatures of the column and the detector are sufficiently lowered (steps S102 to S104), and then the power supply of the gas chromatograph is switched over from an ON state to an OFF state (step S106).

  • Patent number: 10564082
    Abstract: According to improvement of the receptor layer of various sensors of the type for detecting physical parameters (for example, a surface stress sensor, QCM, and SPR), all of high sensitivity, selectivity, and durability are achieved simultaneously. A porous material or a particulate material, e.g., nanoparticles, is used in place of a uniform membrane which has been conventionally used as a receptor layer. Accordingly, the sensitivity can be controlled by changing the membrane thickness of the receptor layer, the selectivity can be controlled by changing a surface modifying group to be fixed on the porous material or particulate material, and the durability can be controlled by changing the composition and surface properties of the porous material or particulate material.

  • Patent number: 10557679
    Abstract: A firearm and tool oiling chamber comprised of an oil less air compressor, sealed chamber, oil atomizer and air filter. Said system introduces air through the oil atomizer breaking oil down to a fine vapor allowing the vapor to cover all surfaces of firearm or tool. As the vapor enters the chamber, being heavier than air it forces air out through the exhaust line and filter. Any escaping oil is caught in filter. The oil is able to cover all surfaces of firearm or tool and to penetrate into areas that hand oiling does not reach using much less oil than conventional methods.

  • Patent number: 10548298
    Abstract: A dog collar light with An LED housing, an electronics housing, left and right-side knobs, a front lens, LED lights, a battery and an elastic attachment band. The LED housing can pivot within arms extending from each side of the electronics housing. The electronic housing also includes a fur guard to help keep fur from blocking the LED lights. The side knobs are used for rotating the LED housing up or down and are made of transparent material so that light can shine out from either from the front lens of the LED housing or from the left and right knobs. The LED lights are powered by a battery located within the electronics housing. The elastic band attaches to the electronics housing and holds it to a dog collar so that the LED lights can shine light onto the ground in front of the dog.

  • Patent number: 10550751
    Abstract: Methods and systems are provided for a particulate matter (PM) sensor assembly positioned downstream of a diesel particulate filter in an exhaust system. In one example, a method may include rotating the PM sensor assembly inside an exhaust passage to generate an output, the rotation based on exhaust flow conditions within the exhaust passage. By rotating the PM sensor assembly via a bearing, a rate of soot particulate accumulation on a sensor element of the assembly may be maintained at a desired level, and independent of a direction of exhaust flow inside the exhaust passage.

  • Patent number: 10545108
    Abstract: A thin film gas sensor device includes a substrate, a first pillar, a second pillar, a nanostructured thin film layer, and a first and a second electrical contact. The first and second pillars are supported by the substrate. The nanostructured thin film layer is formed with a semi-conductor material including holes. The semiconductor material is configured to undergo a reduction in a density of the holes in the presence of a target gas, thereby increasing an electrical resistance of the nanostructured thin film layer. The first and the second electrical contacts are operably connected to the nanostructured thin film layer, such that the increase in electrical resistance can be detected.

  • Patent number: 10534094
    Abstract: A gas sensor instrument comprises a housing formed of two parts (102, 10) and a diffusion chamber inside the housing. The diffusion chamber is formed from two parts (106, 108) and at least one of the diffusion chamber parts is formed integrally with one of the housing parts. This allows a reduction in size of the instrument without compromising the size of the diffusion chamber. Additionally, a tubular projection is formed integrally with one of the housing parts to form part of a Faraday cage for shielding an amplifier circuit of the instrument.

  • Patent number: 10466151
    Abstract: A method is provided for measuring density of a fluid by means of at least one at least sectionally curved measuring tube. The measuring tube is adapted to be flowed through by the fluid and concurrently to be caused to vibrate over a wanted oscillatory length, namely a tube length measured from a first tube end to a second tube end, a length which is greater than a minimum separation of the second tube end from the first tube end. According to the invention, among other things, also a tilt measured value representing an inclination of the at least one measuring tube in the static resting position relative to a local acceleration of gravity is ascertained, in such a manner that such represents an angle of intersection between a direction vector of an imaginary first reference axis (y-axis) and a direction vector of an imaginary second reference axis (g-axis).
