Abstract: In order to obtain a sound-broadened image and a clear sound-image discrimination image when producing plural kinds of sounds, the electronic musical instrument and the like provides a sound-image position control apparatus. This apparatus at least provides a signal mixing portion (e.g., matrix controller; MTR1) and a virtual-speaker position control portion (DL10-DL13, KL10-KL13, KR10-KR13, AD10-AD13). Herein, the signal mixing portion mixes plural audio signals supplied from a sound source (17) and the like in accordance with a predetermined signal mixing procedure so as to output plural mixed signals. In order to control positions of virtual speakers (VS10-VS13) which are emerged as sound-producing points as if each kind of sounds is produced from each of these points, the virtual-speaker position control portion applies different delay times to each of plural mixed signals so as to output delayed signals as right-side and left-side audio signals to be respectively supplied to right-side and left-side speakers (SP(R), SP(L)). Thus, the sound-image positions formed by the virtual speakers are controlled well, so that the person can clearly discriminate and recognize each of the sound-image positions. When applying this apparatus to the game device providing a display unit which displays an animated image representing a visual image of the air plane and the like, by adequately controlling the sound-image position, it is possible to obtain a brand-new live-audio effect, by which the point of producing the sounds corresponding to the animated image can be moved in accordance with the movement of the animated image which is moved by the player of the game.

Abstract: In a method for monitoring the state of clogging and/or calcification of heat exchangers (4) in heating systems, follow-up operating data (temperatures T1' to T6', pump speeds np', ns') are sensed at regular intervals during the operation hereof and are compared with the original operating data (temperatures T1 to T6, pump speeds nP, ns) which were sensed in an initial state, e.g. upon initial start-up. In the event of a permissible deviation of the follow-up operating data from the original operating data being exceeded, which is usually attributable to clogging and/or calcification of the heat exchanger (4), a corresponding disruption signal is emitted. Corresponding to this method, a conventional heating system is provided with a monitoring device (28) by means of which clogging and/or calcification of the heat exchanger is automatically examined at regular intervals. <IMAGE>

Abstract: Certain colorants become insoluble under specific and well-defined pH conditions. By forcing a colorant to become insoluble on the page, migration of the colorant is inhibited, thereby helping to reduce bleed between inks of different colors. The colorant is forced out of solution from the ink by contact with another ink having the appropriate pH (either higher or lower than that of the first ink). In particular, an ink containing a colorant comprising a pigment in combination with a pH sensitive dispersant is used in conjunction with an ink of the appropriate pH.

Abstract: An adaptive clock recovery arrangement for deriving a synchronous clock from an asynchronous, packet stream (11) such as an asynchronous transfer mode (ATM) cell stream. The deviation in the magnitude of information stored in a first-in-first-out memory (15) is continually monitored (25), and the synchronous clock frequency, referred to as the adaptive line clock frequency, is adjusted in a plurality of modes, under the control of a processor (29). The adjustment is made in response to a detected increasing condition of the monitored deviation. The adjustments are open-loop adjustments made without continually adjusting the adaptive line clock frequency based on the monitored deviation. Damping is substantially reduced compared with "conventional" PLL arrangements because the open-loop adjustments result in a rapid frequency correction with perfect or nearly perfect deadbeat damping, i.e. without the frequency oscillations that continue after the correct frequency is reached in closed-loop arrangements.

Abstract: It is described an ink jet recording head which has: a pressure chamber (28) which is communicated with a nozzle opening (20) of a nozzle plate (27) and with a reservoir (30) through an ink supply port (29); and a piezoelectric vibrator (21) for, in response to a driving signal, producing volume displacement in the pressure chamber (28), the inertance Mn of the nozzle opening (20) and the inertance Ms of the ink supply port (29) having the relationship of        0.5 < Mn/(Mn + Ms)          is used. The meniscus is rapidly returned to the nozzle opening (20) by an inertial energy which is due to the ink suction to the pressure chamber (28), so that the ink ejection is conducted in the vicinity of the nozzle opening (20), thereby enabling an ink drop which is substantially spherical to be ejected. The contraction time period of the piezoelectric vibrator (21) for sucking ink into the pressure chamber (28), and an expansion time period of the piezoelectric vibrator (21) for ejecting an ink drop from the nozzle opening (20) are set to be 1/f (where f is the Helmholtz's resonance frequency) so that the residual vibration of the meniscus is reduced to a level as low as possible, thereby allowing the record head to be driven at a high speed.
