Abstract: The musical tone synthesizing apparatus synthesizes a musical tone signal in response to the wind instrument and the like to thereby simulate a resonance tube providing with several sound holes each opened or closed by each finger of a performer. Herein, the input signal is delayed by the predetermined delay time, and then the predetermined operational process corresponding to the signal-scattering operation is carried out on the delayed signal. The coefficient used in this operational process is varied in response to the open/close state of each sound hole. Thus, the operation result can simulate the musical tone to be sounded from the resonance tube of the wind instrument and the like.

Abstract: The present paper describes a machine with a mobile lower platform (A) which automatically produces pockets on articles of clothing. The fabric (T) is held firmly between the abovelying blades (L1, L2) and the lower mobile platform (A) during sewing operations, in order to avoid dragging the fabric (T) across the lower platform which generally produces sewing defects along the borders of the pockets. A pressing arm (E) is lowered by means of a piston (F) with an adjustable damper (H). Furthermore, the fold-over blades (L1, L2) are L-shaped in order to maintain the fabric (T) stretched over the cutting and sewing assembly, thereby avoiding wrinkling of the material while it is being sewed.

Abstract: It is normal in video monitoring devices for a relatively large number of monitoring cameras and a smaller number of monitors to be provided. The monitoring cameras are then switched alternately through to the monitors with a video matrix. Since the transmission lines cause distortions, equalizing amplifiers are fitted in front of the video matrix in order to compensate for the distortions. For this purpose, one equalizing amplifier is required for each transmission line. The object of the invention is to reduce the number of equalizing amplifiers required. This reduction can be achieved by disposing the equalizing amplifiers after the video matrix and by extracting the required equalization values from a memory dependent on the selected input and by feeding them to the equalizer as correction values. Through this arrangement, the number of equalizing amplifiers required is equal only to the number of outputs present on the video matrix. <IMAGE>

Abstract: In a cordless key telephone system, access units are located in groups corresponding to service areas for broadcasting radio signals on a control channel or on an assigned speech channel to cordless stations. A main controller selects one of the access units for each service area in response to an incoming call from the switched telephone network and sends a first alert signal to the selected access units to cause them to broadcast a recurrent sequence of second alert signals containing the identifiers of standby cordless stations. The second alert signal is received by each standby cordless station and an ACK signal is transmitted if the received signal contains its identifier. The ACK signal is copied by each access unit for transmission to the main controller, whereupon it returns a proceed-to-assign signal if the number of the received copies of the ACK signals is equal to the number of all standby stations. The proceed-to-assign signal is received by the selected access units and a channel assignment signal is broadcast indicating the assigned channel. On receiving it, each station is switched to the assigned channel and one of the stations in each area transmits an end-of-switching signal to cause the access units to broadcast ringing signals containing the identifiers of the alerted stations. In response to a given cordless station going off hook, an off-hook signal is sent from it and copied by the associated access unit for transmission to the main controller, which returns a turn-on signal to allow the given station to activate its speech circuit.

Abstract: Whereas in the case of scanners using polygonal mirrors and a flat image plane there is no problem in generating a desired beam geometry in the case of scanners having a cylindrical image plane this has been up till now an unsolved problem. The invention presents a method and devices for solving this problem even here. An orientated, preferably elliptical, spot is generated on the image plane. It is advantageous in this case for the major semiaxis of the elliptical spot to be orientated transverse to the scanning direction. The beam is formed either by     - an aspherical reflecting surface, - an aspherical optical system mounted on or immediately in front of a reflecting surface, or by - a rotationally symmetrical, aspherical block of lenses mounted about a reflecting surface.   <IMAGE>
