    Abstract: In an image forming apparatus, a calculation processing portion includes an input portion and an input-portion abnormality determining portion. The input portion is connected to a temperature detection portion. When an abnormality detection circuit has detected that a temperature detected by the temperature detection portion is an abnormally heated temperature, the input-portion abnormality determining portion determines whether or not a first temperature calculated as a temperature of a fixing member is lower than a predetermined second temperature, and upon determining that the first temperature is lower than the second temperature, determines that the input portion is abnormal.

    Abstract: A wear-proof tester to evaluate an anti-frictional performance of surface treatment carried on a needle cage. The needle cage is subjected to flex under the centrifugal force of composite revolution and rotation. Wear-proof test of surface treatment is carried by sliding contact between the outside circular surface of the retainer and the inside circular surface of the outside wheel. The retainer with no roller is fastened on a rotary shaft with leaving a clearance between them. A radial load is applied to retainer through a test outside wheel to get the retainer flexed to make sliding contact over a predetermined area between the outside circular surface of the retainer and the inside circular surface of the outside wheel. This wear-proof tester is applicable to the wear-proof tests of various materials other than the wear-proof test of the retainer made of various materials.

    Abstract: The temperature of the tread surface part of a tire is increased by running the tire in contact with a drum. The increase in the temperature of the tread surface part is due to the heat of friction between the tread surface part and the drum. Because large increases in temperature indicate that the friction is causing a large amount of wear, it is possible to forecast with ease the amount of wear of the tire from the increase in temperature of the tread surface part. The temperature of the tread surface part can be measured using a thermography machine, and the wear in the tread can be determined by looking at an image that shows the temperature.

  • Patent number: 6671471
    Abstract: An image heating apparatus in an image forming apparatus includes a temperature detecting element, an elastic member for pressuring the temperature detecting element and a film for covering the temperature detecting element. Conventionally, since the elastic member whose width is smaller than the width of the film completely covers the temperature detecting element and the elastic member, it has been necessary to prevent the film from interfering with and riding onto a heater holder equipped beside those parts. For improvement of the above problem, the elastic member whose width is larger than the width of the film is provided to be able to pressure an edge of the film.

  • Patent number: 6632252
    Abstract: A sensor system includes a housing that houses a thermally sensitive sensor, a transmitter portion and a power source. Preferably, the sensor device is encapsulated to protect the components from the environment. The transmitter generates a signal in response to the sensor detecting a temperature in a vehicle component that exceeds a predetermined temperature. A receiver is located remotely from the transmitter to receive the signal. The power supply generates electricity when the temperature of the vehicle component achieves an initial threshold temperature that is less than the predetermined temperature.

  • Patent number: 6612736
    Abstract: An estimated brake rotor temperature is provided including a cooling effect during active braking as well as when braking is inactive. The cooling effect is based on a difference between the rotor temperature and sensed ambient temperature and is also preferably based on wheel speed. In an active braking mode, a heating effect is provided based at least on sensed wheel speed. If no brake pressure signal is available, the heating effect is further based on vehicle deceleration. The heating effects for front and rear brake units are relatively compensated for differences in heat generation due to load shifts during braking, the compensation being preferably based on vehicle deceleration. The brake rotor temperature estimation is realized in a programmed digital computer but does not use computer resource hungry exponential functions.

  • Publication number: 20030110860
    Abstract: To enhance a detecting capability for monitoring a bearing assembly and also to minimize complication of the structure resulting from increase in functionality, a vehicle mounted bearing assembly 51 includes inner and outer members 2 and 1 with rows of rolling elements 3 operatively interposed between the inner and outer members 2 and 1, and a rotation detecting sensor 4. A sensor output from the rotation detecting sensor 4 is digitalized by a digitalizing unit 101 and is subsequently transmitted wireless by a transmitting unit 105. One or both of status detecting sensors 52, 53 for detecting different statuses of the bearing assembly 51 other than rotation such as temperature and vibration occurring in the bearing assembly 51 may be additionally employed. A signal coordinating unit 104 may also be used for coordinating the respective sensor outputs from the rotation detecting sensor and the status detecting sensors to enable those sensor outputs to be transmitted wireless by the transmitting unit 105.

  • Patent number: 6430459
    Abstract: A roll sensing system for measuring the pressure distribution and nip width in a nip roll press. The sensing system comprises a strip having sensors thereon, the strip being placed in a nip press, for sensing the pressure at several locations therealong. At one end of the strip lies electronics associated with the sensors. The electronics communicate with an optional multiplexer and a bidirectional transmitter for signal transmission to an external signal conditioner and an external computer. The computer determines pressure values and nip width values at various locations along the strip, and communicates with a display which provides a visual, graphical and/or numerical data to the operator. Optionally, a control system can be in communication with the transmitter or the computer to initiate crown corrections in response to pressure or nip width readings.

  • Publication number: 20020006154
    Abstract: In accordance with the presence or absence of heat, a transistor shows a relatively rapid change, while a cooling water CLW shows a relatively gentle change. The temperatures of both members settle down to approximately equal temperatures when no heat is generated in the transistor. At this time, the temperature of one of the transistor or the cooling water and the amount of energization of the transistor are used to estimate the temperature of the other member. This method is applied to other temperature estimations, such as estimation of the temperature between a stator coil and a stator iron core of a motor etc.

  • Patent number: 6113263
    Abstract: A contact-type thermometer which is supported by fixing a contact plate having a supporting bar on both sides of an annular elastic member that is formed by connecting both sides of an elastic sheet. A temperature sensitive portion is arranged between the annular elastic member and the contact plate to hold a portion attached to the contact plate of the annular elastic member and the opposite side using the support. In addition, clearance fixing the supporting bar into a guide hole that is long from side to side in a holder such that the contact plate contacts an object to be temperature measured in parallel. The elastic force acting on the back of the contact plate under the condition of the elastically deforming annular elastic member becomes slightly flat, wherein the contact plate does not float more than a distance to the surface of the object to be temperature measured, so the temperature can be accurately measured.
