IPC: H04S1/00
Filed: 1993-03-17
Abstract: PURPOSE:To obtain the acoustic reproduction device reproducing a sound field having a sense of spread and of depth without losing a sense of localization by using two forward left and right speakers only in the stereophonic reproduction. CONSTITUTION:A main signal and a sound field signal are added and the sum is fed to one unit 6e in two speaker units 6a, 6b of the same performance and arranged close to each other in each of left and right channels and the sum of the main signal and the polarity inverted sound field signal is fed to the other unit 6b. Thus, a radiation characteristic of the sound field signal is an 8-shaped dipole characteristic and since a notch direction of radiation of the sound field signal is directed toward a listener 7 when a major axis of the radiation of the main signal is directed toward the listener 7, the sound field signal is not directly reached to the listener 7 and the reflected sound in a room is dominant.

Title: Protector of air conditioner
Inventor: SAITO KATSUHIKO
IPC: H02P27/06
Filed: 1990-03-08
Abstract: PURPOSE:To detect an open-phase operation by a method wherein a current which is made to flow by a power converting operation is detected and the waveform of the current is shaped and the period of the shaped current waveform is calculated and compared with a predetermined value and, if the result of the comparison exceeds the predetermined value, the power converting operation is discontinued. CONSTITUTION:While the compressor 5 of an air conditioner is normally operated by the output of a power converting means 4, a current detecting means 6 detects a current flowing into the power converting means 4 and outputs it to a waveform shaping means 7. The waveform shaping means 7 shapes the waveform of the output of the current detecting means 6 and outputs a pulse wave having a period equal to the period of the waveform of the detected current. A period calculating means 8 receives the shaped pulse wave and calculates its repetition period 'tau'. By comparing the period tau with a predetermined value 2tau, the existence of an open-phase operation is judged.

Title: Thermal head
Inventor: KURITA KENJI
IPC: B41J2/335
Filed: 1989-03-09
Abstract: PURPOSE:To prevent density unevenness of printing from occurring by a method wherein for double-sided adhesive tape, adhesive strength at both ends in an arrangement direction of a thermal resistor is made larger than adhesive strength at a central part in the arrangement direction. CONSTITUTION:For a double-sided adhesive tape 10, a V-shaped cut is notched from both side parts so that a width of a central part 10a becomes less than a width at both end parts 10b, and a ceramic heating element substrate 2 is bonded to a heat sink 3 instead of a double-sided tape 8. Therefore, since the heating element substrate 2 at both end parts is more solidly bonded fast to the heat sink 3 by comparing with that at the central part, a heating head performs high quality printing without unevenness in density.
