Title: Back light
Inventor: SEKINE MITSUHARU
IPC: G02B6/00
Filed: 1994-02-21
Abstract: PURPOSE:To thin a back light and prevent light leakage by making the opening width of a reflecting cover almost the same with the thickness of a light diffusing plate end face, in a structure wherein light is made incident from the side face of the diffusing plate having a reflecting face on its bottom and radiated out of the face opposite to the reflecting face. CONSTITUTION:LED light R emitted out of a LED element 4 goes straight or is reflected on a reflecting sheet 11 or a reflecting end face 1a to be incident upon a diffusing plate 12. The light R is repeatedly reflected between the inner face of a radiating face 18 and a diffusing face 13, which is the bottom of the diffusing plate and the light reaches the radiating face 18 at critical angle or more is radiated to the outside. In this case, a gradation pattern is formed in the diffusing face 13 due to a large number of projected parts formed more densely as the distance from the element 4 is larger and the light is diffused and reflected efficiently and at the same time the brightness of the light R is made uniform. With this structure, since the width X of the opening part of a reflecting cover 1 in the light emitting part and the thickness (t) of the diffusing plate 12 are set almost equal to each other, the gap between them is eliminated to thin the structure and the light R is prevented from leaking outside.

IPC: H04J3/00
Filed: 1993-02-10
Abstract: PURPOSE:To correctly output data by providing a differentiating circuit, and outputting a signal obtained by allowing an output of a prescribed 4-input OR gate to be subjected to wave tail differentiation, as a reset signal. CONSTITUTION:When a reproducing clock exists in an AGC signal inputted from a demodulator, its signal becomes 'H'. Subsequently, when a clock 1 being a reproducing clock inputted from the outside is continued, an AGC signal 2 inputted from the outside becomes 'H'. Also, the clock 1 becomes an output 4 of a 2-input AND gate 3 without being masked by the signal 2 in the gate 3 and as for four outputs 6-9 of a first 4-bit register 5, only one becomes 'H' in order at every rise of the output of the gate 3. Next, the 4-input AND gate 5 executes an OR operation of a carry output of four pieces of (v)-ary counters. By the obtained timing, the 4-ary counter 20 controls four outputs of the register 5 and a multiplexer 27. Moreover, when an output subjected to wave tail differentiation by a differentiating circuit 18 is set as a reset signal, data can be outputted correctly.

Title: Electronic timepiece
Inventor: SUGANO FUMIO
IPC: G04C9/08
Filed: 1988-02-02
Abstract: PURPOSE:To securely drive a rotor even if the rotor has a difference in phase, etc., by generating in-phase phase correcting driving pulses at the time of an in-phase detection signal and opposite-phase phase correcting driving pulses at the time of an opposite-phase detection signal. CONSTITUTION:When a detecting circuit 16 generates an H signal as an in-phase detection signal, a T-FF 6 is reset. Consequently, the output Q' of the T-FF 6 which outputs an L signal by inverting the edge at the fall of a 1st driving pulse after being reset from being reset is switched to an H signal and held, and the output Q is switched to an L signal and held. The phase correcting driving pulses are applied to a 1st inverter 12 through an inverter 25. When the L signal as the opposite-phase detection signal is generated, the T-FF 6 is not reset and the output Q of the T-FF 6 which is inverted and outputs the H signal is held as it is. Then phase correcting driving pulses are applied to a 2nd inverter 13 through an inverter 23, etc. In this case, the rotor 15 which can not rotate normally because of the opposite phase is driven with this phase correcting driving pulse to rotate normally.
