Title: Received data processor and its method
Inventor: SATO MASAHIKO
IPC: H04L29/02
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To wait for the signal of an AV link in a low speed mode. SOLUTION: When a micro controller 11 receives data from the AV link in the low speed mode, a signal decoding part 21 detects the fall of a start bit. Then, a speed switch part 23 starts a clock switch operation and data decoded in the signal decoding part 21 is accumulated in a RAM 22 during the time when the operation is executed. When an operation for switching a clock from the low speed to the high speed terminates, a process part 24 reads and analyzes data accumulated in the RAM 22 and executes a necessary processing and makes a response.

Title: Power source device
Inventor: SHIMOKAWA SADAJI
IPC: H02M7/06
Filed: 1981-11-11
Abstract: PURPOSE:To obtain a positive-negative symmetrical output through simple constitution by connecting the parallel circuit of a rectifier equal in polarity to the half cycle of an AC output on the low level side and impedance in series to one AC output terminal. CONSTITUTION:At the high potential side of the secondary winding 14 of a transformer 12, and AC output terminal 17 is provided through the parallel circuit of a rectifier 15 and impedance 16. In a half cycle equal in polarity to a rectifier 18 on a DC output side, a current flows through the rectifier 15 to obtain a cut output waveform and in the next half cycle, the current flows through the impedance 16 parallel to the rectifier 15. Therefore, a voltage drop across the  impedance causes a decrease in the peak of the output waveform between output  terminal 17 and 21, so the value of the impedance 16 is selected properly to obtain an output waveform which is nearly symmetrical on the zero level.

Abstract: PURPOSE:To surely detect the presence/absence of video signals inside a microcomputer by fetching composite synchronizing signals obtained by synchronizing- separating the video signals to an input port and judging the presence/absence of the video signals based on the level of the input port.

Title: Optical communication equipment
Inventor: FUKUHARA KOTARO
IPC: H04B10/50
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To reduce a light rising time of a light emitting element without peaking. SOLUTION: When a signal voltage of a voltage corresponding to a normal signal is added to a first light emitting element as shown in (a), a light waveform of the first light emitting element is outputted as in (b). As (c) shows, a second light emitting element is allowed to emit only for a time until the emitted light quantity of the first light emitting element becomes about half. Then, as (d) shows, a light waveform is outputted wherein the light quantities of the first and second light emitting elements are added. Since the second light emitting element begins to be put out at the time when the emitted light quantity of the first light emitting element becomes approximately half, the emitted light quantity remains almost the same as the first light emitting element, while only its rising speed is increased.
