Patent EP-0192480-A1 (EP)
Inventor: YOSHIKAWA YUKIHIRO
IPC: C07C205/38
Filed: 1986-02-20
Abstract: Bis(3-nitrophenoxy) derivatives of aromatic or bridged aromatic hydrocarbons are derived from m-dinitrobenzene and dihydroxy derivatives of said hydrocarbons by a condensation reaction in dipolar aprotic solvents in the presence of bases. The bis(3-nitrophenoxy) derivatives obtained are successively reduced to afford bis-(3-aminophenoxy) derivatives. This is a new method for reacting the dihydroxy-derivatives with m-dinitrobenzene, and hence can prepare novel bis(3-aminophenoxy) derivatives such as 4,4'-bis(3-aminophenoxy)biphenyl, 1-[4-(3-aminophenoxy) phenyl]-1,3,3-trimethyl-6-(3-aminophenoxy)indan, 6,6'-bis(3-aminophenoxy)-3,3,3',3'-tetramethyl-1,1'spirobiindan, and methyl substituted 2,2'-bis[4-(3-aminophenoxy) phenyl)propane.

Abstract: A recording apparatus enables audio and video signals to be recorded on a plurality of recording tracks (AT, VT) on the same recording medium (D). A series of temporally consecutive audio signals can be recorded across a plurality of tracks (AT). On at least the audio track (AT), information signals including a leading track number (NF), the next following track number (Nn) and the number (Nc) of a video track bearing corresponding video signals, are recorded. The track number data of the information signals on these audio tracks (AT) are written in corresponding positions of a digital table memory (38). These information signals (control code data) are recorded on a predetermined control track (CT) on the recording medium (D) such that a series of desired audio signals and corresponding video signals can be selectively reproduced smoothly and promptly by first reading the control track (CT) and then reproducing the audio and video tracks in accordance with the control code data information.

Abstract: Particularly in resistance spot welding or resistance soldering of a contact to a support, e.g. a miniature contact to a contact spring, the process described leads to a minimisation of the contact hardness losses during the process by introducing a short-time energy pulse. Further advantages consist in a reduction in the damage to the surface of the contact material, the increasing of the strength of the joint zone, greater uniformity within the joint zone and the lengthening of the electrode life by three to five times as well as an extremely small transfer of copper from the electrode to the contact surface, the said transfer being at the limit of detectability. In the process, a contact element, e.g. made of silver, is welded to a contact support by means of a welding aid, e.g. composed of Cu Ni 30 Fe or by means of a brazing solder, e.g. composed of L Ag 15 P5, or by means of carrier material and brazing solder, or is connected to the said contact support by flux-free brazing. In order to achieve the abovementioned advantages, the energy pulse used in the process is an extremely steep-flanked controlled energy pulse which at the same time has a high current intensity. This results in rapid introduction into the joint zone of the energy required for joining, unnecessary heating, associated with power loss, of the areas of the material adjacent to the joint zone being eliminated at the same time. <IMAGE>

Abstract: A synchronous demodulator for the demodulation of ultrasound burst waves reflected by a moving object comprises an operational amplifier (30) wired as integra­tor (resistor 36, capacitors 32, 33). When a MOSFET switch (37) in the input line of the amplifier is conductive, it operates as a low-pass filter. If, on the other hand, this switch is in the high-impedance state, the actual value is stored by the capacitor (32, 33). The circuit is switched between filtering mode and hold mode by a demodulator clock (41). The circuit incorporates the functions of demodulator, a low-pass and a hold circuit.
