Filed: 1988-12-23
Abstract: PURPOSE:To constitute the alarm timepiece which generates voices of various person only by replacing an IC card by storing voice data on the IC card in word units, combining words and editing a document, and synthesizing a speech. CONSTITUTION:A microcomputer 6 outputs a two-byte instruction consisting of data 1 and data 2 to a speech synthesizing LSI 9. Those data 1 and 2 are entered into a document editing table 5. For example, the data 1 consists of seven bits 0 - 6 and specifies words 1 - 127. The data 2 consists of 4-bit channel specification information and 4-bit reduction specification information. In this case, the speech synthesizing LSI 9 synthesizes a speech with four channels and specifies which channel is used for the synthesis. When reduction is specified, 0 - -24 dB are selectable. Consequently, speed data are stored on the IC card in word units, words are combined to edit a document and synthesize a speech, and the document is modified only by changing the card.

IPC: H01J29/07
Filed: 1987-12-25
Abstract: PURPOSE:To give a uniform tension by fixing flat a shadow mask to a frame having a greater thermal capacity than the mask, heating to a high temp., and cooling only the shadow mask through blasting of cold wind etc. CONSTITUTION:By welding, a shadow mask 2 is fixed flat to the whole circumference of a mask pulling frame 3 having a great thermal capacity, and this frame 3 is put in a furnace to heat to 90 deg.C for stabilization and taken out of the furnace when the shadow mask 2 gets constant temp., followed by blasting of the air 5 with temp. adjusted to 30 deg.C to the whole mask 2 so that only the mask 2 is cooled to approx. 30 deg.C. Because the mask pulling frame 3 has great thermal capacity, its temp. does scarcely sink, while the shadow mask 2 cools in the condition that its periphery is fixed to the mask pulling frame 3, so that a tension is generated over the whole. This gives a uniform tension over the whole stably.

Filed: 1993-12-24
Abstract: PURPOSE:To restore the correct read data despite the presence of a data storage medium of a different type which transmits the read data of serial output of a single bit and parallel output of plural bits with use of the same pseudo random signal. CONSTITUTION:A data storage medium 12 is provided with memories 30-1 and 30-2 which perform the serial reading operations. Then one of prescribed four types of pseudo random signals is outputted to the parallel data of two bits which are simultaneously read out of both memories 30-1 and 30-2 every time a data reading instruction is received from a reader/writer 10. The reader/ writer 10 acquires the self-correlation with the received signal by the correlation computing elements 22-1 to 22-4 with the signal equal to those pseudo random signals of the medium 12 defined as a reference signal. Then the reader/writer 10 detects the largest one of four self-correction values at a comparing part 24 and outputs the corresponding 2-bit data. A type command is produced form a type deciding part 15A before the data are read, and the correct data bits are restored in response to the type answer information given from a type answer part 28A.
