Abstract: A movable contact assembly for use in a circuit breaker includes a movable contact arm having wall portions and an elongated contact member located adjacent to and between the wall portions of the movable contact arm. A supporting member attached to the back of the elongated contact member is engaged with the movable contact arm by means of a pivot pin passing through a pair of aligned holes.

Abstract: A speech-synthesizer timepiece disclosed herein is adapted to provide audible sounds indicative of time and/or calender information. The audible sounds are followed by an adjective phrase which represents such a unit of the preceding time and/or calender information as month, day, day of the week, hours, and minutes. The adjective phrase consists of one or more audible sounds like that indicative of the body of the time and/or calender information.

Abstract: A programmable music instrument comprises an indicator for indicating a particular tone having a clef and a relevant scale on a screen, a liquid crystal display, and an electrochromic display cell or the like. A series of input keys is provided for providing digital information defining a musical note, the number of which corresponds to that of the notes in an octave. An octave changing member is employed for selecting a desired tone. The indicator is operated to indicate a selected stave for the particular tone. The octave changing member comprises a switch operated in a relationship with the screen. It may comprise a driver circuit for the liquid crystal display, the electrochromic display cell or the like.

Abstract: A synthetic speech calculator is provided which is capable of generating an audible sound signal which can be representative of keyed data, sequences of keyed data (and errors), processed data, the contents of a memory or the contents of a counter. The sound signal can be suppressed under certain specific circumstances or made soft in intensity. A synthetic-speech calculator includes the keyboard consisting of digit keys and function keys, a desired number of registers for storing 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.

Abstract: A synthetic-speech calculator includes a keyboard consisting of digit keys and function keys and, if desired, 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-analogue converter for convering 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. There are further provided means for producing audible sounds indicative of not only numerical information but also its associated conditional information having a particular meaning with respect to that numerical information, for example, position information, index information, tabulation information, etc.

Abstract: A hand-written pattern is introduced through a matrix input means and stored in a matrix memory. An alarm time is set and stored in an alarm time memory. A detection circuit develops a detection output when the current time reaches the alarm time set in the alarm time memory. In response to the detection output, the hand-written pattern stored in the matrix memory is read out and displayed on a matrix display panel.

Abstract: Wiring patterns and key contact patterns are directly formed on an inner surface of a casing of an electronic calculator. A printed board or a substrate can be eliminated by mounting electrode elements on the inner surface of the casing to establish electrical connection with the wiring patterns formed on the inner surface of the casing, thereby enabling the reduction of size, especially thickness, of the electronic calculator.

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.

Abstract: Digital information related to plural kinds of stitch patterns is stored in a memory means such as an ROM disposed within an electronic sewing machine. A keyboard means is provided for selecting desired stitch patterns stored within the ROM at operator's choices. Output signals of the keyboard means are temporarily stored in a dynamic memory means such as a shift register. A digital control circuit is arranged so that the ROM develops signals related to the stitch pattern selected through the shift register, to thereby control a stitch forming mechanism.

Abstract: In a sewing machine including a static memory for storing digital information related to the positional coordinates for each stitch of a predetermined stitch pattern, a dynamic memory such as a shift register is provided for temporarily storing the digital information derived from the static memory. Output signals of the dynamic memory are applied to a needle positioning mechanism and a work feed mechanism through driving means. In a preferred form, input means are provided for modifying the digital information temporarily stored in the dynamic memory, thereby modifying the stitch pattern.

Abstract: In a combination timepiece and calculator, a keyboard receiving section is provided within the body of the combination timepiece and calculator for accommodating a slidable keyboard therein. Switching means are associated with the keyboard receiving section so as to place the combination timepiece and calculator in the timepiece mode when the keyboard is housed within the keyboard receiving section, and to place the combination timepiece and calculator in the calculator mode when the keyboard is drawn out from the keyboard receiving section.
