Title: Two-step type a/d converter employing chopper type comparator
Inventor: AIURA MASAMI
IPC: H03K5/08
Filed: 1994-06-13
Abstract: PURPOSE:To keep excellent linearity by avoiding an offset error, that is, an offset error caused by an analog switch in details. CONSTITUTION:The two-step type A/D converter employs a chopper type comparator. The switch element 40m-1 of a switch matrix 4 setting the reference input of host and subordinate comparators 1, 2' shares the reference switch (2Bk-1) of the subordinate comparator 2' and the number of switch elements inserted to reference and comparison input lines of both the host and subordinate comparators 1, 2' is the same as each other, then an offset given to each input is equal to each other. Thus, the number of components is reduced by one (an exclusive reference switch in the subordinate chopper comparator) than those of a conventional A/D converter.

Title: Bearing oil reservoir device
Inventor: MATSUO YOSHINORI
IPC: F16N39/04
Filed: 1983-07-20
Abstract: PURPOSE:To reduce temperature of a guide bearing, by fixing a C-shaped fin on a heat receiving side of a heat pipe inserted into a hole formed through a bearing frame to prevent bubbles from adhering to the fin. CONSTITUTION:A lubricating oil is injected from a self-pump hole 3 by a self- pump action due to rotation of a runner 2 in operation, and is circulated in an oil reservoir in such a direction as depicted by arrows. As a C-shaped fin 30 on a heat receiving side of a heat pipe 20 inserted into a hole 10 formed through a bearing frame 9 is directed to the runner 2, a circulation flow is picked up to generate a vortex flow inside the fin 30 and permit the oil to flow from an upper portion to a lower portion of the fin 30. Inside the fin 30, light bubbles 27 only are collected to grow and rise in the oil, thereby reducing the bubbles adhered to the fin 30. Accordingly, heat conduction to the heat pipe 20 is improved and temperature of a guide bearing 8 is reduced.

Title: Checking apparatus of leakage of gas
Inventor: CHIN KOTSUKA
IPC: G01M3/20
Filed: 1989-05-24
Abstract: PURPOSE:To detect minute leakage of a gas positively even when the pressure in an analyzing pipe portion is high by modulating an output generated by a magnetic field generating means with a modulating wave of a predetermined frequency and a predetermined amplitude and, detecting the leakage from the size of an ion current obtained by an ion collector. CONSTITUTION:An ion current measuring part 30 is comprised of an alternating current amplifying part 31, a synchronization adjusting part 32 and an indicating part 34. An output of a modulating part 33 is fed to an ion selecting part 22 which is an electromagnet. The mass-charge ratio of the selecting part 22 is between 3 and 4. More specifically, in a magnetic field of a predetermined intensity or of an intensity close to the predetermined intensity, an output generated from the magnetic field generating means 22 is modulated with a modulating wave of a predetermined frequency and a predetermined amplitude, so that the leakage of a gas is detected from the size of an alternating current voltage obtained by an ion collector at this time. Since a background ion is detected as a direct current voltage by the ion collector, it is not amplified by the alternating current amplifier. Accordingly, the leakage of the gas can be correctly detected.

IPC: G01R31/02
Filed: 1988-05-31
Abstract: PURPOSE:To detect even an instantaneous disconnection, by varying intensity of emission of an LED according to a binary signal to detect interception and variations in intensity of the emission of the LED from the output of a photo transistor. CONSTITUTION:When a disconnection occurs in transmission paths (a) and (b), an LED normally emitting light halts the emission with the disconnection.
