To reduce the size and weight of an engine body and improve the mountability and maintainability of transmitting rods in a valve train for an OHV engine having a crankshaft, a crankcase for rotatably supporting the crankshaft, a camshaft incorporated in the crankcase, cylinder heads connected to the crankcase, engine valves operably provided in the cylinder heads, and the transmitting rods for transmitting a valve operating force due to the rotation of the camshaft to the engine valves. The transmitting rods as pull rods are arranged on one side of cylinder barrels. One end portion of each transmitting rod is formed with an engaging portion disengageably engaged with a hook portion of a mating member. An engine body or a guide member, fixed to the engine body, is provided with a guide portion for guiding the engaging portion to the hook portion of the mating member.

A display apparatus including an optical sensor in its peripheral region is intended to response to visible rays efficiently by preventing a malfunction due to the reaction of the optical sensor to near ultraviolet rays. For this purpose, a display apparatus that includes an active matrix substrate (2) having a pixel array region (8) in which a plurality of pixels are arranged on a base substrate (14) is configured as follows: an optical sensor (11) is provided in a peripheral region (9) located around the pixel array region (8); a color filter (22) for display is provided on the opposite side of TFTs (6) from the base substrate (14); and a color filter (23) for an optical sensor is provided on the opposite side of the optical sensor (11) from the base substrate (14).
摘要:
A diffuser is provided on a beverage supply tube having a beverage supply valve. Air bubbles formed in the beverage in the final stage of filtration for extraction are removed from the beverage, and only the gas is passed through the beverage supply tube, whereby the tube is air-blown. Thereafter, the beverage remaining in the diffuser is drained through a drain tube. A pair of electrodes are provided on the beverage supply tube which leads the extracted beverage to the serving cup portion, in order to detect the presence and absence of the beverage based on the conduction caused by the beverage between the electrodes. An air pipe for supplying air to the extraction chamber from an air pump is provided with a branch, and a pressure sensor for detecting the pressure within the extraction chamber during the filtration is attached to the branch. The on/off duty ratio of the air pump is controlled based on a pressure signal from the pressure sensor, so as to control the pressure within the extraction chamber below a predetermined pressure.

The image reading device of the present invention includes (i) a sensor substrate which functions as a photoelectric transfer element having a photodetecting TFT and a pixel capacitor and (ii) a driving IC for applying a voltage to a gate electrode of the photodetecting TFT so as to drive the photodetecting TFT into an ON state or an OFF state. The driving IC applies a voltage, whose polarity is opposite to average polarity of a voltage making the photodetecting TFT in the OFF state, to the gate electrode of the photodetecting TFT in an arbitrary period. Thus, it is possible to provide the image reading device which can suppress variation of a photodetecting TFT property (resistance value) which is observed in a short time.
摘要:
A sensor substrate (20) which includes phototransistors (7), each having a photosensitive semiconductor layer, and auxiliary capacitances (17) connected to the drain electrodes D of the corresponding phototransistors (7), and detecting ICs (25) for detecting a photoelectric conversion amount of the sensor substrate (20), which is connected to a source electrode S of the phototransistor (7), are provided. In the auxiliary capacitance (17), a predetermined amount of charge is stored, and also stored are the charge as generated by an emission of a light beam onto a photosensitive semiconductor layer in the non-conductive state of the phototransistor (7). Each detecting IC (25) detects a photoelectric conversion amount of the sensor substrate (20) based on the amount of charge remaining in the auxiliary capacitance (17).

摘要:
A power source control system for controlling a power source of a terminal device, including a timer in which an actuation time is preset and a control circuit which receives a signal from the timer. At the actuation time, the timer outputs the signal to the control circuit such that the control circuit performs on-off control of the power source of the terminal device.
