Title: Optical module
Inventor: WATANABE TSUTOMU
IPC: G02B6/42
Filed: 1998-04-03
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of interference due to stray light between adjacent optical elements and to eliminate electromagnetic wave interference (EMI). SOLUTION: An optical component 28 provided with a light emitting element 25 and a light receiving element 26 side by side on a mount 24 is provided in an IC package. A ferrule which contains optical fibers 27(A) and 27(B) is fitted integrally to the IC package. In this case, the end surface of the optical fibers 27(A) and 27(B) face the light emitting element 25 or light receiving element 26. The light emitting element 25 is covered with a metallic cover 31. Light (stray light) other than light entering the optical fibers 27 from the light emitting element 25 is cut off by the cover 31, so the stray light never exerts any adverse influence on the adjacent light receiving element 26.  Further, an electromagnetic wave generated when the light emitting element 25 emits light does not leak out because of the magnetic shield effect of the cover 31, so electromagnetic wave interference can be suppressed.

Title: Manufacture of superconducting multiple core compound billet
Inventor: NAGASU YOSHINORI
IPC: H01B13/00
Filed: 1991-04-12
Abstract: PURPOSE:To provide a manufacture method of a superconducting multiple core compound billet wherein a number of superconducting element wires can easily be line-up arranged. CONSTITUTION:Since superconducting element wires 2 are arranged in a plurality of divided type dummy rings 1 installed in a coaxial state at specified intervals, an arrangement state of the superconducting element wires can be monitored and corrected through a clearance part of each of the divided dummy rings and therefore line-up arrangement of the superconducting element wires 2 is easy. While an aggregation 3 of the line-up arranged superconducting element wires is being bundled by a metallic tape 4, the divided type dummy rings 1 are removed sequentially so that a line-up arrangement state of the superconducting element wires 2 can never be broken. Since a number of superconducting element wires 2 are bundled with a metal thin wire such as the metallic tape 4 to be filled in a metal tube 6, filling density of the superconducting wire 2 can be retained at a high value.

Filed: 1980-08-11
Abstract: PURPOSE:To detect the characteristics of a gas to be measured, by measuring the difference between the propagation velocities of ultrasonic waves in the reference gas and the gas to be measured. CONSTITUTION:When different gases are filled in vessels 1a, 1b respectively, and an electric signal is applied to an input terminal 5, said signal is converted to an ultrasonic wave signal via transducers 2a, 3a for an input, thereby an ultrasonic wave to be radiated in gas. Said ultrasonic wave propagates in gas within respective vessels 1a, 1b and is received with transducers 2b, 3b for an output, and after being converted to an electric signal, supplied to output terminals 6a, 6b. Between the outputs taken out from the two transducers 2, 3 for input and output, a phase difference corresponding to the difference of propagation velocity of the ultrasonic wave in gas is produced. Said device functions effectively even in a case of measurement for a difference of the ultrasonic wave produced by conditions such as a temperature difference or a concentration difference or gas pressure in a case of the same kind of gas.

Title: Ac voltage measuring apparatus
Inventor: MIYAZONO SHUNICHI
IPC: H03M1/60
Filed: 1990-04-25
Abstract: PURPOSE:To facilitate circuit integration and to reduce the size and the cost of an AC voltage measuring apparatus by measuring an input voltage based on the occupation rates of output pulses from first and second comparators which make comparison, respectively, with first and second references voltages. CONSTITUTION:AC signals are commonly fed from an input terminal IN through a capacitor C to the non-inverted input terminal of a comparator 21 and the inverted input terminal of the other comparator 22. When positive and negative peak values of an AC input signal are larger than Vra, Vrb, respectively, outputs from both comparators 21, 22 go H even during an interval T21 where positive instantaneous value of the AC input signal is higher than Vra or an interval T22 where negative instantaneous value is lower than Vrb. During intervals T01, T02 where the instantaneous value of the AC input signal is between Vra and Vrb, outputs from both comparators 21, 22 go L. Since each interval is equalized and the number of sample in each interval is also equalized, an AC voltage value corresponding to an occupation rate calculated in an operating circuit 35 can be derived, as a measurement, from a ROM 36.

Title: Magnetic shielding parts
Inventor: MOMOSE KENICHIROU
IPC: G11B23/087
Filed: 1980-08-11
Abstract: PURPOSE:To obtain effective magnetic shield by adjusting the component of low Ni permalloy including Cu. CONSTITUTION:An alloy is made to have a composition essentially consisting of Ni 60-77wt%, Cu 1-25wt% and the balance Fe including inevitable impurities as residue. This composition allows magnetic permeability which is second to none conventional high Ni permalloy and permits application to magnetic shielding parts. If Ni is 60% or less, the magnetic permeability is low for any adjustment, and if Ni is 77% or more, resource saving is ineffective. Cu of 1% or less has no adding effect and Cu of 25% or more injures hot workabitiy. If the composition of Ni 65-72%, Cu 10-18%, Fe as residue is applied to a shielding plate for cassette tape and the composition of Ni 69-72%, Cu 13-16%, Fe as residue is applied to a shielding case for magnetic head, magnetic shield is very effective. Furthermore, with a small quantity of Mo, W, Nb, Si and the like being added, magnetic characteristics can further be improved.

Title: Thread cut detecting device
Inventor: MAKINO SHOZABURO
IPC: B65H63/032
Filed: 1986-05-13
Abstract: PURPOSE:To improve the detection precision with the simple constitution by averaging the induced potential of a pair of detection electrodes which induce the charged electricity on a thread, synchronously in a same phase, and operating a relay circuit by diffenentiation-amplifying each output signal. CONSTITUTION:When a thread 1 travels, the induction signal due to the commercial electric power and the detection signal corresponding to the electric charge on the thread are superposed onto the detection electrodes 2a and 2b, and applied onto terminals Pa and Pb. Since the induction signals are synchronized in a same phase, the signals are offset. While, since the detection signals are asynchronously induced in a same phase, the superposition signal of the both is generated in the output of a differential amplifier 5, and the output voltage R of a recitifier 6 becomes high potential. Therefore, the output signal of a comparator becomes zero, and a relay circuit 7 is input into into inoperative. When the traveling of the thread 1 stops because of cut, etc., the thread traveling signal induced in the direction electrode is eliminated, and the relay circuit 7 is put into operative, and the cut of thread is detected.
