Title: Abnormal temperature detecting device of gas insulation apparatus
Inventor: MORI EISAKU
IPC: G01K1/02
Filed: 1981-03-27
Abstract: PURPOSE:To detect temperature within an apparatus accurately from outside, by a method wherein an ultrasonic probe is contacted with outer side surface of an insulator to support a high-voltage conductor, and an indicator is connected to the probe and detects propagation time of the ultrasonic wave. CONSTITUTION:An ultrasonic probe 6 generates ultrasonic pulse if voltage from a pulse generator 7 is applied thereto. Pulse from the ultrasonic probe 6 is propagated into a conductor supporting insulator 2 and reflected by an inner conductor 3 and returned to the probe 6. Pulse which does not strike the inner conductor 3 also reaches opposite surface of the insulator and reflected there and returned to the probe 6. The returned ultrasonic wave is converted by the probe 6 into high-frequency and enters an indicator 9 through a receiver 8. Since high frequency voltage from the pulse generator 7 also enters the receiver 8 directly, time interval between the oscillation pulse and the reflecting pulse can be measured at the indicator 9. Temperature can be detected, since the time interval varies with temperature.

Title: Gate oscillating circuit
Inventor: MURAKAMI MASAHARU
IPC: H03K3/282
Filed: 1981-03-30
Abstract: PURPOSE:To stabilize the frequency of oscillation to the fluctuation of the power supply voltage, by using a diode which is biased forward from the power supply via a resistance for a resistance of a feedback circuit that feeds back the output of an amplifier. CONSTITUTION:An oscillating circuit is formed with a direct coupled amplifier consisting of transistors TRQ11 and TRQ12 plus a feedback circuit including a capacitors C11 and C12 plus a diode D21. A TRQ14 is connected in parallel to the TRQ11 to control the start and stop of the oscillation, and at the same time an output is extracted through waveform shaping TRQ13. A resistance R21 is connected between the anode of the diode D21 and the power supply terminal to bias forward the diode D21. Thus the impedance of the D21 has fluctuation with the fluctuation of the power supply voltage. Then the fluctuation is compensated for the frequency of oscillation to the fluctuation of the power supply voltage.

Title: Resistance film structure of position sensor
Inventor: SEKIYA MITSURU
IPC: F02D9/00
Filed: 1997-02-14
Abstract: PROBLEM TO BE SOLVED: To reduce the deterioration in the linearity of output due to the wear of a resistance film and to improve an output accuracy by laminating a resistance paste on a low-resistance paste and forming the resistance film. SOLUTION: A low-resistance paste is laminated so that an electrode film 5a formed on a resistance substrate 5 is covered, and further a resistance paste is laminated on it and a low-resistance film 5c and a resistance film 5b are successively formed on it. In this case, the edge part of the resistance film 5b is reduced so that the low-resistance film 5c is exposed from the resistance film 5b, and a connector terminal 6 is connected to the electrode film 5b via the low-resistance film 5c. A brush 3 that is clamped in one piece with the slider of a position sensor contacts the resistance film 5b and is slid.  However, even if the resistance film 5b is locally worn out due to the slide, the synthetic resistance of the resistance film 5b and the low-resistance film 5c is small and the deterioration in the linearity of output after the long-term use of the position sensor can be suppressed to a small value.

Abstract: PURPOSE:To obtain optical fiber having a large difference of specific refractive index between a core and a clad by adjusting a bulk density of a core corresponding part at the outermost peripheral part to be higher than the bulk density of internal part, and heat-treating a heaped body in an atmosphere contg. F-contg. gas for a certain period in a stage for making the heaped body transparent by heating. CONSTITUTION:O2 and H2 are ejected by feeding the gas from a feeding port 4 and 5, respectively, using a multicore tube burner 3A, 3B. At the same time, SiCl4 as feed gas, GeCl4 as dopant gas, etc. are fed through a feeding port 7 together with Ar gas as carrier gas. A reaction is thus caused, and simultaneously, shielding Ar gas is fed through a feeding port 6, causing successive deposition of fine glass particles from a tip end of a starting base material 8 toward an axial direction. Thus, a bulk density of a core corresponding part at an outermost peripheral part is adjusted to a larger bulk density than that of the internal part by elevating a surface temp. Then, obtd. soot base material is heated, if necessary in an atmosphere contg. Cl2, then heated for at least a specified period at 1,150+ or -150 deg.C in an atmosphere contg. F-contg. gas. Thus, F is added easily to only a clad corresponding part.

Title: Network access method
Inventor: KAWAKAMI TETSUYA
Filed: 1985-03-13
Abstract: PURPOSE:To place priority the network access right by a host by sending longer a jam signal from a terminal device and retransmitting succeedingly collided message when the host detects the collision of transmission messages to the network. CONSTITUTION:The host 1 and each terminal device 2 combine a transmission frame, sense a carrier and start transmission when it is confirmed that the network NW 3 is idle. When collision takes place in the NW 3, the transmission is interrupted immediately and the jam signal is sent to ensure the collision. When number of trials is less than a prescribed value, after a random time is elapsed, the re-transmission is executed from the carrier sensing. In detecting the collision, a longer jam signal is sent from a terminal device 2, the host 1 makes immediately re-transmission. Thus, the collision with the message from the collided terminal device 2 is avoided. Since the host 1 makes re- transmission at collision without CSMA, the host 1 occupies the NW 3 with a priority over the terminal device 2.
