A receiving circuit comprises a transimpedance amplifier 3 including an inversion amplifier 2 for amplifying an input current IN, and a feedback resistance R1 connected between an input and an output of the inversion amplifier 2, a comparison circuit 4 for comparing an output OUT of the transimpedance amplifier 3 with a certain desired reference value, and outputting a result of the comparison, and a control circuit for holding the comparison result, and generating an AGC signal 20 for adjusting a gain of the transimpedance amplifier 3. The transimpedance amplifier 20 has a function capable of gain adjustment in accordance with the input AGC signal 20. The control circuit 5 performs gain adjustment until the output OUT of the transimpedance amplifier 3 exceeds the reference value so that an appropriate gain is obtained. Therefore, even when an input has a wide dynamic range, it is possible to prevent signal saturation and a distortion in output waveform in the transimpedance amplifier, so that appropriate reception can be invariably performed and a signal having a stable duty can be output.

Endoscopic biopsy forceps as one of endoscopic treatment tools of the present invention include a flexible insertion section. The proximal end portion of the insertion section is received in an operating section. A closely wound coil is exposed to the proximal end portion of the insertion section, and the proximal end portion of the coil is enlarged in diameter to form an enlarged-diameter portion. A protrusion is formed in an operation section body, and the enlarged-diameter portion of the coil is locked by the protrusion to restrict the movement of the coil, thereby preventing slipping off of the insertion section.

A novel winding device of special arrangement insusceptible to vibration of a drive motor. A winding roll (2) is supported on a winding arm (1) and combined with a drive motor. The drive motor has a body (3) and a rotary shaft (4) penetrating of the body to project from the opposite sides thereof. Furthermore, a pair of bearings (5) are provided on the winding arm and the rotary shaft is supported rotatably on the opposite sides of the body. A rotation-stop (6) is provided between the winding arm and the body and, in the rotational direction of the rotary shaft, the body is restricted by the rotation-stop and does not rotate. Consequently, a web material can be wound around the winding roll by rotating the winding roll through the drive motor.

An organic thin film manufacturing method and manufacturing apparatus is disclosed in which control of the heating method of the organic material can be carried out simply, temperature control of the organic material to be subjected to vapor deposition is easy, and the reproducibility and stability of the film thickness of the organic thin film obtained are excellent. According to the organic thin film manufacturing method an organic material is fed in a vapor state into a vapor deposition apparatus positioned in a vacuum chamber from a material introducing part positioned outside the vapor deposition apparatus to form a thin film of the organic material on at least one substrate disposed inside the vapor deposition apparatus. The material introducing part has a structure such that the pressure inside can be set independently of that inside the vapor deposition apparatus, and it also has an exhauster independent to that of the vapor deposition apparatus.

A brush unit includes a carbon brush 1, a substantially straight brush arm 2 for holding the carbon brush 1, and a brush base 3 connected to the brush arm 2. The brush base 3 is provided with a receptacle terminal 5 formed by cutting and raising the brush base 3, and thereby the brush base 3 is formed with a base hole 6 corresponding to the receptacle terminal 5. The brush unit is installed to a case cover 4 at two locations of a fixing portion in which the brush arm 2 is fixed to the brush base 3, and a brush base end portion integral with a base portion of the receptacle terminal 5, so that noise is reduced by decreasing a vibration component in an axial direction of the motor at a sliding portion at which the carbon brush 1 slides with-respect to a commutator at the time of motor rotation, and also brush tension is not changed when outside terminals are inserted through outside terminal insertion holes.
摘要:
In a current comparison type latch, during a reset mode of the current comparison type latch where the clock signal is at the “L” level, transistors which are disposed along the current path extending from the high potential power supply line to the low potential power supply line are turned OFF while transistors which connect the high potential power supply line to two output terminals are turned ON, so as to bring the potential of each of the two output terminals to a logic level (the “H” level or the “L” level), thereby preventing a through current from flowing from the high potential power supply line to the low potential power supply line. Therefore, a high-speed and high-precision current comparison is made while reducing the through current during a reset mode.

There is disclosed a leakage diagnosis of an evaporative system in an internal combustion engine, and more particularly there is disclosed an evaporative system in which a more accurate leakage diagnosis can be effected using a change in the pressure in the evaporative system, and such a diagnosis method is also disclosed. The evaporative system includes a gauge line having a gauge valve, which gauge line branches off from an evaporative gas line or an evaporative gas purge line, and communicates with a point upstream of an engine throttle valve or with the ambient atmosphere, a pressure sensor for detecting the pressure in the evaporative system, and a purge valve. A leakage diagnosis of this system is effected based on detected values of the pressure sensor obtained by opening and closing the purge valve and the gauge valve. Therefore, accurate results of the diagnosis can be obtained.
