Title: Houling prevention device for simultaneous bidirectional speaker-phone
Inventor: NAKAI MICHIO
IPC: H04R3/02
Filed: 1988-01-29
Abstract: PURPOSE:To obtain a stable houling preventing effect by making an acoustic wave propagated from two sets of speakers two sounds of the phase-inversed same level with each other in the sound receiving position. CONSTITUTION:Voice signals inputted from telephone lines L1, L2 are outputted to the first speaker 9 through a hybrid transformer T1 and a low-pass filter 12 from two wire - four wire conversion circuit 11, but at the same time, inputted to a BBD 15 from the transformer T1. After being delayed for a set delay time, the signals are outputted to the second speaker 10 via a low-pass filter 17, etc., to be propagated as an acoustic wave. The delay time is set equal to the time necessary for the acoustic waves emitted from the speakers 9, 10 to reach a microphone 4. Therefore, the both acoustic waves comes the phase- inversed same level with each other at time of reaching a transmitter, hence they acts to offset each other. As a result, only the speaker voice of a transmitter is made incident to the microphone 4, thus the occurring of a houling can be suppressed.

Title: Ultrasonic applicator
Inventor: IWASAKI SEIJI
IPC: A61B18/00
Filed: 1991-02-13
Abstract: PURPOSE:To enhance the efficiency of drive of an ultrasonic applicator by providing a flange portion in a part corresponding to the node of vibration ahead of an ultrasonic vibrator, and connecting a vibrating member to the flange portion in such a manner that the front end face of the vibrating member serves as a vibrating face located at the antinode of the vibration, and making the vibrating member movable relative to the vibrating face. CONSTITUTION:A voltage is applied to an ultrasonic vibrator 40 and then the vibrator vibrates in its longitudinal direction. The vibration generated is transmitted to a vibrating member 41 and ultrasonic wave is transmitted to a human body from a vibrating face 46 via a ultrasonic transmission liquid 50 retained in a water bag 47. In this case the ultrasonic vibrator 40 is supported at its flange 43 to a casing 45, the flange 43 being located at the node of the vibration: since the inner film 47 of the water bag 47 is movable relative to the vibrating face 46 of the vibrating member 41 which is connected to the flange portion 43, the constraint of the vibrating face 46 located at the antinode of the vibration is small and vibration is not restrained. Therefore, the efficiency of drive of the ultrasonic vibrator is enhanced.

Title: Thermal transfer recording material
Inventor: OKABE EIICHI
IPC: B41M5/392
Filed: 1987-01-31
Abstract: PURPOSE:To obtain superior printing properties even in paper or inferior smoothness by adding one or more than two kinds of amino acid derivatives selected from among amide N-acylaminate, ester N-acylaminate and amine salt of N- acylamino acid to a thermomelting ink layer. CONSTITUTION:In a thermal transfer recording material consisting of a base and at least a thermomelting ink layer provided on the base, the thermomelting ink layer contains one or more than two kinds of amino acid derivatives selected from amide N-acylaminate, ester N-acylaminate and amine salt of N-acylamino acid. The amino acid derivative contained in the thermomelting ink layer gelatinizes wax even in a molten state. Wax has almost no flocculation power when molten because of a sudden decrease in viscosity when it melts. However, the amino acid derivative gives gelatization effect to wax even when the latter is molten, thus preventing the sudden decrease of viscosity and improving flocculation. Therefore, the transfer effect of ink is increased and subsequently, even paper of inferior smoothness printed sharply.
