Patent JP-H11145913-A (JP)
Title: Preamplifier
Inventor: HONMA KANENORI
IPC: H04B10/40
Filed: 1997-11-10
Abstract: PROBLEM TO BE SOLVED: To provide a preamplifier with which an optical. reception signal can be normally received without the occurrence of waveform distortion even when prebias is contained. SOLUTION: An optical signal is converted to a current signal by a photodiode(PD) 1 and converted/amplified to a voltage signal by a trans- impedance type amplifier circuit 12. When the input signal from the PD 1 is accompanied with the prebias, the offset level of an automatic offset control(AOC) 11 is shifted to timing corrected just for the prebias by a reset signal 6. In the case of containing the prebias more than a fixed amount and in the case of containing no prebias, the offset '0' level of an output signal from the amplifier circuit 12 is different. Therefore, the optimum threshold voltage in each case is set by a first automatic threshold control(ATC) 8 and a second ATC 9 and while receiving a control signal from a prebias detection circuit 7, the outputs of the first and second ATC are selected by a selector 10.

Filed: 1991-10-28
Abstract: PURPOSE:To conduct amination of a hydroxylated compound under highly safe conditions by reducing a combination of the hydroxylated compound with an amino compound with the hydrogen contained in a hexagonal CaCu5-type hydrogen storage alloy containing rare earth element or Ca and Ni. CONSTITUTION:A combination of (A) a hydroxylated compound (e.g. ethanol) with (B) an amino compound (e.g. aniline) is incorporated with (C) a hydrogen- contg. hydrogen storage alloy with the main phase consisting of a compound having hexagonal CaCu5-type crystal structure bearing both M (rare earth element or Ca) and Ni as the essential elements (e.g. LaNi5), and the reaction temperature of the resultant system is adjusted to 80 deg.C under agitation. Then, a reduction is made for 4hr with the hydrogen released from the alloy followed by recovering the hydrogen gas and reaction liquide, and the reaction product is separated from the reaction liquide, thus efficiently obtaining the objective aminated product (e.g. N-ethylaniline) by amination through hydrogenating reduction under such a highly safe condition as to be <20kg/cm<2> in hydrogen gas pressure.

Title: Boiling heat transfer pipe and its manufacturing method
Inventor: KIDO OSAO
IPC: B23K9/00
Filed: 1990-11-13
Abstract: PURPOSE:To provide a substantial improvement over a heat transfer performance of a boiling heat transfer pipe by a method wherein a helical continuous groove is continuously formed in respect to an axial direction of a pipe, a welding part when the pipe is formed is also formed helically in respect to an axial direction of the pipe, and the groove and a welded projection projected toward an inner circumferential surface of the pipe at the welded part are always kept in parallel to each other at the inner circumferential surface of the pipe. CONSTITUTION:A boiling heat transfer pipe 11 is used as a part of a heat exchanger. Refrigerant during boiling stage is flowed in the pipe. At this time, a V-shaped groove 13 is helically formed at an inner circumferential surface 11a of the boiling heat transfer pipe 11 in respect to an axis (n) of the pipe. A welded projection 15 is also helically arranged in respect to a direction (n) of the pipe axis in such a way as it becomes in parallel with a continuous groove 13, thereby liquid refrigerant flowing at a bottom part of the pipe of a flow passage 12 of the horizontal boiling heat transfer pipe 11 is sufficiently sucked up within the groove 13 under a capillary phenomenon and a guide of the welded projection 15, resulting in that the entire inner circumferential surface 11a of the pipe is wetted by a thin refrigerant liquid film and a heat transferring performance is substantially improved due to an increased effective heat transfer area as well as the thin refrigerant liquid film flow. At this time, the welded projection 15 does not become a trouble against the liquid refrigerant flow, but rather it becomes a guide for guiding a helical flow and so the pressure loss may not be increased.

Filed: 1997-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a speaker system that can raise a sound pressure level at a low-frequency range by specifying an impedance of an impedance compensation circuit. SOLUTION: An impedance compensation circuit of an impedance Zc, which turns an electric impedance of a speaker system into a constant-resistance in order to prevent a decline of efficiency, is inserted serially in the second voice coil. At this time, the impedance compensation circuit decides the impedance Zc so that the electric impedance as the speaker system becomes the constant-resistance when a passive radiator system cabinet is used. That is, this impedance compensation circuit becomes what an equation indicates in a formulaic expression. In the equation, each of L1 and L2 indicates inductance and each of C1 and C3 indicates capacity and each of rc1 and rc2 indicates resistance.

Filed: 1996-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a compact antenna fixture that mounts an antenna on a moving body by using a permanent magnet where the antenna does not come off even when a strong vibration and shock are given to the fixture. SOLUTION: Permanent magnets 2a, 2b fitted to legs 1a, 1b of an antenna 1 are attracted to an outer face of a mount metallic plate 3 being an outer case of a moving body. Electromagnets 6a, 6b that are opposed to the permanent magnets 2a, 2b are placed in an inner face of the mount metallic plate 3. A shock/vibration sensor 7 placed to the mount metallic plate 3 detects a vibration and shock of the moving body and inputs a resulting signal to a CPU 8. When the detected vibration and shock exceeds a prescribed value, the CPU 8 allows an electromagnet drive circuit 9 to excite the electromagnets 6a, 6b. Attracting force of the permanent magnets 2a, 2b coupled with the antenna 1 to the mount metallic plate 3 is increased by exciting the electromagnets 6a, 6b and the antenna 1 is not removed from the mount metallic plate 3 even when vibration and shock are applied.
