Patent EP-0309721-A1 (EP)
Inventor: MORIMOTO YASUAKI
IPC: G11B13/04

Abstract: Optical-recording medium having a light-transmitting substrate layer. 
<??>CDs are such recording media, on which data are stored in so-called pits, that is to say depressions in a light-reflecting layer following the light-transmitting layer. In the case of magneto-optical discs, data are stored in a magneto-optical layer by magnetising in the one or the other direction of magnetisation. For reading the data stored in this way, use is made of the Kerr effect, which produces a measurable rotation of the polarisation plane when a linearly polarised light beam is reflected at the magneto-optical layer. Although both recording media - CD and magneto-optical disc - already have a high storage capacity, a considerable increase in the storage capacity is of great benefit, in particular for computer applications and as a video disc. 
<??>In order to increase the storage capacity considerably, the light-transmitting substrate layer (1) is followed by a light-reflecting magneto-optical layer (2), in which data can be stored on the one hand by magnetising and on the other hand by means of depressions (3), so-called pits. The light-transmitting substrate layer (1) may also be followed by a partially transmitting magneto-optical layer (2) without pits (3), which is then followed by a light-transmitting layer (10). In this or a following layer (11), data can be stored by means of pits (3). 
<??>Storage medium for computers, video disc, CD.

Abstract: The first (T₁) and the second (T₂) output transistor of an amplifier arrangement are push-pull driven by means of a drive circuit (10) having two transistors (T₁₁, T₁₂) which are each loaded by a current source (T₁₃, T₁₄). Currents which are a measure of the currents flowing through the first (T₁) and the second (T₂) output transistor are generated by a first (20) and second (30) current measuring means. These currents are applied to a negative feedback means (40) which controls the current intensity of the current sources (T₁₃, T₁₄) in such a way that the harmonic mean value of the currents flowing through the first (T₁) and the second (T₂) output transistor is substantially equal to a reference value.

Abstract: Process and harvesting attachment for harvesting fruit on stalks of plants of tall growth, for example maize or sunflowers, the fruit being separated from the stalks and collected as a crop and the stalks being comminuted to form chaff; the invention relates furthermore to a harvesting attachment for this, which can be connected individually or severally to an agricultural harvesting appliance and which has two oppositely rotating draw-in rollers, at least one of which is drivable from the harvesting machine via an intermediate gear, the draw-in rollers being preceded by a picking plate with a picking gap extending essentially parallel to the draw-in rollers, and picking gap and draw-in rollers forming the draw-in path for the plants to be harvested, in which attachment a reliable chopping of the stalks is obtained and which, furthermore, can be used on the modular principle for harvesting machines, and the use of which will be economical especially as a result of a reduction of the power requirement; this is achieved by means of two draw-in rollers (20) which rotate oppositely to one another at different circumferential speeds and which grasp the stalks together with the fruit and draw them through a gap-like picking orifice (15) separating the fruit from the stalks, the grasped stalk first being broken by tearing strips (23) provided on the draw-in rollers (20) rotating oppositely to one another at different circumferential speeds and then being torn to pieces in the region of the outlet as a result of the speed difference between the corresponding tearing strips (23), the number and position of the tearing strips (23) being such that, according to the circumferential speeds, when a tearing strip of the first of the draw-in rollers (20) passes through the draw-in path, likewise a tearing strip of the second of the draw-in rollers (20) passes through this draw-in path which the tearing strip assigned to the faster draw-in roller leaves in advance. <IMAGE>

Abstract: 2.1 In communication exchanges to which subscriber sets and also external lines are connected with different dialling methods in each case, uniform procedures are to be used during the transmission of the dialling information from the subscriber set to the external line, in which procedures it is not necessary to determine which dialling method is used by a subscriber set. The dialling information coming from a subscriber set with multifrequency push-button dialling is in this case to be connected through directly on the speech path when it is connected to an external line which also operates in accordance with the multi-frequency method. This direct connecting-through of the dialling information should not be disadvantageously influenced by dialling conversion procedures. 2.2 The dialling information is always supplied via control devices to the external line seized in each case, independently of the dialling method of a subscriber set. When an external line operated in accordance with the multi-frequency dialling method is seized in the outgoing direction, the presence of audio-frequency dialling information is determined with the aid of an audio-frequency receiver connected to the speech path. If this is so, only the direct sending-out of the dialling information is enabled and the multi-frequency transmitter provided for the conversion of dialling information is inhibited. 2.3 In this procedure, it is not necessary to determine the dialling method of a subscriber set from which an external line is seized. The multi-frequency push-button dialling information is connected through directly without delay and without being influenced by conversion processes. <IMAGE>

Abstract: An extended definition television (EDTV) system transmits, receives and displays both EDTV and NTSC signals using a NTSC channel bandwidth. The system produces an EDTV broadcast signal having a picture with a 16:9 aspect ratio and at least one adjacent horizontal border to produce an overall image aspect ratio of 4:3. Picture information is also selectively modulated onto the horizontal border. The EDTV broadcast signal is transmitted in a NTSC format, and a receiving means is provided comprising a display means with a 16:9 aspect ratio, a detector means for deter­mining whether an EDTV or other type of signal is being received, and an expansion means responsive to the detector means to produce an expanded picture for display. When an EDTV signal is received, it is expanded and filtered ver­tically and is expanded horizontally and the 16:9 picture is displayed on the 16:9 display means. The receiving means derives picture information from both the picture portion and the border portion of the EDTV signal. When an NTSC signal is received, it is displayed on the 16:9 display means with at least one vertical border so that the NTSC picture has a 4:3 aspect ratio. The EDTV signal is also compatible with and may be received and displayed on standard NTSC receivers as a 16:9 picture with at least one horizontal border.

Abstract: A surgical stapling instrument is provided having safety and sequencing features to mandate proper operation of the instrument during surgical clamping and stapling of tissue. The instrument is powered by pressurized gas, and includes a manual control for supplying gas to a clamping mechanism in the stapler head and a trigger for actuating a stapling mechanism therein. The instrument prevents actuation of the trigger until the tissue has been clamped. The trigger may not be actuated to implant staples until a trigger safety has been actuated. Following actuation of the stapling mechanism, the instrument is either automatically reset to its initial condition, or may require manual control by the user to restore the clamping and stapling mechanisms to their initial conditions. The instrument affords correct sequencing of operation and prevents inadvertent stapling.
