Abstract: In an elastic coupling of disc-type construction, in particular a split flywheel for an internal combustion engine, an elongate spring is arranged between the two coupling halves rotatable with respect to one another. The spring, which is substantially extended in the relieved condition, is divided by the installation of wedge-shaped spring cups into two or more subregions, the longitudinal axes of which are arranged at an angle to one another. A spring of low stiffness, favourable for certain operating conditions, is obtained in this way, while the spring is composed of essentially straight parts. This gives a spring which is economical to produce, is loaded in a favourable manner in operation and, at the same time, is not exposed to any wear. <IMAGE>

Abstract: A light spot position detector, which detects the two-dimensional position of a light spot projected onto a light receiving element (1) with four quadrant light receiving parts (1a-1d), has an amplifier (7) for amplifying detection signals transmitted from the respective light receiving parts individually, an arithmetic circuit (9) for transmitting a first position signal and a second position signal corresponding to the two-dimensional position, and a variable resistor (7a-7d; 9a-9d) for adjusting the gains of the amplifier and the arithmetic circuit with respect to the detection signals. With this configuration, the amount of crosstalk between the first and second position signals is restrained within a given range, the crosstalk occurring when there are variations in gain of the amplifier (7) and of the arithmetic circuit (9) with respect to the respective detection signals. When the light spot position detector (1) is incorporated into an optical head and the optical head (10) is designed such that the movement of the objective lens (3a) causes a shift in the light spot, the displacement of the objective lens can be correctly detected, achieving accurate tracking control and focussing control.

A wide detection bandwidth is also obtained by providing a semiconductor optical amplifier (10) having two current injection electrodes. A bias current (20) is supplied through both current injection electrodes, and both electrodes produce optical gain. However, only one of the electrodes is used for optical signal detection.

Abstract: A thermal print head having a plurality of resistive heat elements and associated individual current sources which are enabled allowing selectable currents to pass through each of the selected thermal print elements. In a binary mode, the current sources can be operated to select a first or second current level, where the first current level is insufficient to form an optical density in the printed image and the second results in an optical density being formed. Alternatively, the current sources are coupled to binary word decoding networks and resistive ladders for decoding up to 2 n  discrete density codes, where n corresponds to the number of bits in the word decoded at the current driver. 
     The current source for each element is coupled to a voltage reference source through a pair of complementary load resistors and switching transistors such that regardless of the binary value applied, the reference voltage source is loaded by one or the other of the load resistors. In this fashion, the reference voltage is loaded by the same total load resistance regardless of the number of thermal print head elements in the array that are energized for printing at any given time. In a binary, n-bit word decoding embodiment, the resistors of each resistance ladder for each current source and thermal print element effectively function as the total load presented to the reference voltage regardless of the n-bit data value decoded to provide the 2 n  discrete print density levels.

Abstract: The present invention method is carried out with a programmable automatic wire bonder having a linear drive motor. The wire bonder (24) is programmed to bond loose lead frame leads (15) at a second bond position in a novel manner. The lead frame lead to be bonded at second bond is clamped in a work holder that leaves the ends of the lead frame leads loose above the bonding mandrel of the work holder but restrained to a predetermined floating zone that is established within a predetermined distance above the bonding mandrel (17). The bonding tool is programmed to engage the loose lead frame lead at second bond at a predetermined velocity which permits the bonding tool to simultaneously exert an impact force on the wire to be bonded and to clamp the loose lead frame lead. While the bonding tool is applying the impact force and simultaneously clamping the loose lead frame lead a second relatively high bonding force is applied to the bonding tool to complete a second bond without incurring bounce, or transient vibrations while making the second bond.

A window  26  which is substantially transparent to the collimated radiation  24  allows the radiated energy to reach the metal oxide substrate  34 . An etch mask  32  may be positioned between the radiation source  20  and the substrate  34 . The metal oxide substrate  34  and liquid ambient  30  are maintained at a nominal temperature (e.g. 25 °C). Without illumination, the metal oxide is not appreciably etched by the liquid ambient. Upon illumination the etch rate is substantially increased.
