Patent DE-2808577-A1 (DE)
Inventor: TANIMOTO AKIRA
IPC: G10L19/00
Filed: 1978-02-28
Abstract: A synthetic-speech calculator includes a keyboard consisting of digit keys and function keys and one or more mode selectors, a desired number of registers for storing numerical information entered by the depression of selected ones of the digit keys, a read-only-memory for storing a large number of digital codes as sound quantizing information, counter means for specifying the address of the memory so as to take a specific digital code out of the memory, a digital-to-analog converter for converting the specific digital code taken out of the memory into an audible sound signal, and a loud speaker driven by the audible sound signal and producing an audible sound. The synthetic-speech calculator is adapted such that the audible sound signals are derived via the loud speaker by at least two different methods of sound generation. For example, when a voice start key is depressed, all digits of keyed information are produced in audible form with appropriate pauses. In addition, numerical information is produced by digit by digit in audible form each time a voice start key is depressed. Numerical information is produced in a 3-digit group mode, each of the 3-digit groups being audibly produced each time the voice start key is depressed. Finally, numerical information may be audibly produced in order of ascending significance relative to the least significant digit or in order of descending significance relative to the most significant digit. The mode selector directs the synthetic-speech calculator how to derive the audible sound signals via the loud speaker.

Title: Electromagnetic drive for dress or hammer - has piston armature generating pneumatic or hydraulic pressure for storage during non-working stroke
Inventor: DOEGE ECKART PROF DR ING
IPC: H02K33/00
Filed: 1978-07-13
Abstract: The electromagnetic drive has an armature formed as a piston working in a cylinder. Work is performed in both the compression and tensile directions instead of using damping in one direction. The efficiency is therefore increased. The tensile or sliding forces (no-load travel) in the cylinder not acting in a direction producing work generate a pneumatic or hydraulic pressure which is stored in a pressure store. This pressure may be amplified before being stored. In the working direction the stored pressure is applied to the piston.

Title: Adaptive delta modulation with conversion to binary signal - uses computer to decide, after scanning during specified time period, which binary value gives best approximation
Inventor: NEUMANN LOTHAR DR RER NAT
IPC: H03M3/02
Filed: 1979-08-08
Abstract: During an adaptive delta modulation an input signal has to be so converted into a binary signal with the lowest possible bit follower frequency that the input signal can be well approximated from the sequence of binary values. The scanning value of the input signal is approximated at a given point in time in such manner that an approximation for a given value is constructed from the first number of bits of a binary signal. After scanning of the input signal at the given point in time, a computer, e.g. a microprocessor, determines between this and another point in time which of both binary values would provide a better approximation, under prescribed procedure. This determined binary value is transmitted to the receiver as the nth bit of the binary signal.
