Title: Bonded plastic moulded ski - has skeletal frame with rows or ribs and ridged side plates
IPC: A63C5/048
Filed: 1970-03-24
Abstract: The ski is made of a bonded plastic, in which is set a one piece metal or plastic frame. The frame extends along the entire length of the ski, and consists of two side plates, which form the edges of the ski, connected by a skeletal bridge. The ribs (10) of this bridge piece are strengthened by at least one cross rib which runs along the entire length of the ski. A vertical knife edge (16) is fitted to each side all. After production of the frame, the ski is moulded round and into it. Ridges (12) in the top of the side plates enhance bonding with the ski upper surface, and a double groove at the bottom of the wall enhances the bond with the running surface. This forms a ski with better hold during side slip or swinging.

IPC: G10L13/02

Abstract: A speech synthesis circuit is provided with a variable frame length data converter and the speech synthesizer is preferably integrated on an integrated circuit chips. The variable frame length data converter reduces the amount of data required to synthesizer human speech at a given quality level. Preferably, a full frame of data includes, a pitch parameter, an energy parameter, a repeat bit and a plurality of speech coefficients. Each parameter or coefficient has a preselected length, but each frame has a variable number of parameters or coefficients associated therewith. The parameters and coefficients are encoded and a particular code of the pitch parameter indicates that the speech is to be unvoiced. An unvoiced frame includes fewer coefficients that a voiced frame and the converter detects this particular pitch parameter and automatically sets the unsent coefficients to zero. The converter also detects the state of the repeat bit for controlling the synthesizing to use the coefficients received during the previous frame as the coefficient to be used to generate speech in response to the present frame. In this embodiment, when the repeat bit comes up, new pitch and energy parameters are inputted therewith. Further, the converters preferably detects particular codes in the energy parameter for determining when a pause occurs or when the last frame of data has been sent.

Abstract: With a gas closure valve (18) for plastic processing apparatuses, in order to avoid streaking in the moulding even at very high gas pressures, and to ensure high flexibility in production without change-times, it is proposed for the valve needle (40) to be controlled by a control plunger (60), which for its part is controlled by means of a working gas volume. When material is fed to the mould (16), the valve needle (40) closes material-tightly, whereas when gas is returned the valve needle (40) remains open until the gas bubble formed in the cavity of the mould (16) has been completely discharged.

Abstract: The invention describes a method of continuously controlling and tracking a position of a welding torch ( 10 ) and welding head relative to a weld seam to be produced on a workpiece ( 16 ), whereby the welding torch ( 10 ), spaced at a distance apart from a workpiece ( 16 ) and the weld seam, effects a pendulum motion which is superimposed on its linear welding motion, during which state variables, in particular an ohmic resistance or a current and/or a voltage, are detected as they change in time. The lateral deviation of the welding torch ( 10 ) from the weld seam, in particular from the welding line centre, and/or the height of the welding torch ( 10 ) above the workpiece ( 16 ) and the welding head are derived from the detected actual values and signals in order to control and track the position of the welding torch ( 10 ). Depending on periodically occurring process phases of a welding process, the measurement value detection routine for at least one measurement signal, in particular to detect the state variable, is run at fixed instants and/or states of the periodically recurring process phases of the welding process.

Abstract: PURPOSE:To obtain a semiconductor device having a three-dimensional structure characterized by excellent heat radiation characteristic, by fixing and connecting semiconductor substrates, on which semiconductor elements are formed, through conductive linking balls, whose side surfaces are covered with insulating materials. CONSTITUTION:A semiconductor substrate 6 for lamination, on which semiconductor elements, interconnections for the elements, Al interconnections and the like are formed, is etched. Linking holes 7 are formed in the substrate 6. Each Au ball 15, whose side surface is covered with an alumina ring 14 as an insulating material, is fixed to a pad 3 on the hole 7. The substrate 6 is overlapped so that each Au ball 23, which is fixed to a pad 22 on a good chip, agrees with the ball 15. The balls 23 and 16 are fixed to each other. Similary, another substrate is laminated on the substrate 6. Then thermal stress can be absorbed by the balls 15, 23 and 24. Therefore, yield of cracks can be prevented. Since a required gap is formed between the substrates, the heat radiation characteristic becomes excellent.

The method is based on finite-difference equations and provides a sequence of signals having a high degree of spectral accuracy compared with presently-used methods. The sequence of signals can be generated in real-time without templates (ROM-stored patterns) because the method requires only two multiplications (16,18) and one addition (12) for each signal value generated in the sequence. The method finds application in dual-tone, multi-frequency (DTMF) telephone dialing systems.
