A thermal-type fluid flow sensor comprises a heating resistor formed on a thin film of a substrate, and plural thermal sensitive resistors configuring a bridge circuit. The thermal sensitive resistors are disposed on the thin film of the substrate so as to be located on an adjacent upstream side and an adjacent downstream side of the heating resistor in a stream direction of fluid to be measured. Resistor traces for the thermal sensitive resistors are formed so that the respective thermal sensitive resistors exhibit substantially equal changes in resistance with each other to distortion caused in the thin film.

A plurality of image bearing members is supported by an apparatus main body and is arranged in a predetermined direction. A belt unit is configured to be detachably mounted on the apparatus main body. The belt unit includes a belt frame, a plurality of belt support rollers, a belt, and a plurality of transfer members. The plurality of belt support rollers is supported by the belt frame. The belt is movably supported by the plurality of belt support rollers and extends in the predetermined direction. Each of the plurality of transfer members is disposed in confrontation with a corresponding one of the plurality of image bearing members with the belt interposed therebetween. A positioning member fixes, relative to the apparatus main body, each of the plurality of transfer members at a position in the predetermined direction when the belt unit is mounted on the apparatus main body.

A belt unit is provided with pressure-receiving parts, and a photosensitive unit is provided with pressing parts that applies pressing force to the pressure-receiving parts when the photosensitive unit is inserted to a main body of an image forming device along a guide groove formed in the main body. The pressing force applied to the pressure-receiving parts presses the belt unit toward a regular mounting position in the main body, so that the mounting of the belt unit is completed at the same time the mounting of the photosensitive unit is completed.

Transmitter and receiver for wireless communications with improved accuracy and stability in radio frequency control. A transmitter mixes an information-carrying signal (first signal) and a non-modulated wave signal (second signal) with a carrier signal, thereby producing a first and second radio frequency signals for radio wave transmission. A receiver mixes those two radio frequency signals to extract the original information signal. While the received radio frequency signals contain some frequency fluctuations and phase noises that have been introduced at the sending end, such unstable components Δf will cancel out at the receiving end.

The present invention relates to a polycarbonate resin composition comprising 100 parts by weight of aromatic polycarbonate resin having a concentration of end hydroxyl group of 100 to 1800 ppm and 0.0001 to 5 parts by weight of fine particle of boride of at least one metal selected from the group consisting of La, Ce, Pr, Nd, Tb, Dy, Ho, Y, Sm, Eu, Re, Tm, Yb, Lu, Sr and Ca, and a heat ray shielding molded product formed by molding the above polycarbonate resin composition. The polycarbonate resin composition and heat ray shielding molded product composed thereof according to the present invention, have especially low haze, are excellent in transparency, have low solar transmittance and sufficient heat ray shielding property (especially, have a function of transparency for visible light and selectively shielding property for infrared ray), and are excellent in mechanical strength and thermal stability at melting. Therefore, these are suitably applicable for windows of general buildings or vehicles, roof materials of arcades and carports, optical materials such as infrared ray cut filters, films for agriculture or the like.

Conventional thermal flow measurement devices lack consideration for automobiles in severe environments. A detection element of the thermal flow measurement device according to the present invention is structured by the provision of a planar substrate made of a material having good thermal conductivity, such as silicon or ceramic, with a thin-walled portion (diaphragm). On the surface of the thin-walled portion, the detection element comprises a heat element as a heater heated to a temperature being different to a predetermined extent from the temperature of the air flow to be measured, temperature-detecting resistors as temperature-detecting means on both sides of the heat element, wiring portions formed of electrical conductors that draw signal lines from the heat element and the temperature-detecting resistors and that have a melting point of 2000° C. or higher, and pads.

An image forming apparatus is configured to form an image on a recording sheet by transferring toner onto the recording sheet. The image forming apparatus may include a container having an inlet configured to receive waste toner, the container defining a storage area having a horizontal dimension greater than a vertical dimension. Also, the image forming apparatus may include a first pump disposed adjacent to the inlet of the container on an inlet side, the first pump configured to feed waste toner from the inlet to an outlet side of the first pump, and a second pump disposed adjacent to the outlet side of the first pump, the second pump configured to feed the waste toner fed by the first pump to an outlet side of the second pump on a side opposite the inlet in the storage area.
摘要:
A circuit board connector has a fixing member (20; 32; 42; 52) for a housing (10) on a circuit board (K). Engaging portions (24) of the fixing member (20; 32; 42; 52) are bent to increase the areas of engaging surfaces (25) in the thickness direction (TD). Thus, contact areas between the engaging portions (24) and restricting surfaces (14) of the housing (10) increase, and forces acting on the contact surfaces are distributed. Accordingly, even if large separating forces repeatedly act on a housing (10), damage and to the engaging portions (24) and restricting surfaces (14) can be prevented.
