Title: Doze detector
Inventor: DAIMON NOBUO
IPC: B60K28/06
Filed: 1993-01-28
Abstract: PURPOSE:To activate an alarm by a parameter by which a dozing state can be substantially judged, by giving an alarm when the winking time obtained by totalizing the winking time above a specified time for each fixed time exceeds a threshold value. CONSTITUTION:An output light 2 from a light-emitting diode 1 is reflected on a human eyeball 3, and the reflected light 4 is sent out to a photodiode 5. The photodiode 5 converts the reflected light 4 into an electrical signal to send it to an amplifier 6, and the amplifier sends out an analog signal to a comparator 7. The comparator 7 generates a digital output signal by a power source voltage exceeding a threshold voltage to send it to a CPU 9. The CPU 9 activates an alarm 10 when the winking time obtained by totalizing the winking time above a specified time for each fixed time exceeds a threshold value. Thus, the doze detection can be performed with higher accuracy.

Title: Manufacture of electrical contacts
Inventor: KOJIMA KIYOKAZU
IPC: H01H11/04
Filed: 1981-01-30
Abstract: PURPOSE:To facilitate removal of burrings produced on an electrical contact piece and to prevent attachment to this contact piece by employing as an abrasive a precious metal or its alloy with a higher hardness than that of the electrical contact piece. CONSTITUTION:When a grinding process is applied for the purpose of removal of burrings produced on an electric piece, an abrasive of precious metal or its alloy is used which has a higher hardness than that of the electrical contact piece in concern. This will facilitate removal of burrings produced on the contact piece and there is not much risk of attachment to the contact surface because of its high toughness. Even though an attachment has occurred as in the worst case, an always stable contactibility is assured because the abrasive consists of a precious metal or its alloy which can offer excellent anti-oxidation and anti-sulfurization performance.

Filed: 1996-01-29
Abstract: PROBLEM TO BE SOLVED: To improve the wettability of a thin film with a lower electrode by specifying the structural component of a coating liquid for the formation of a thin film. SOLUTION: When a ferroelectric thin film comprising a Bi laminar compd. containing Sr, Bi and Ta as the component elements is formed by a wet method, a methoxypropanol soln. containing each metal alkoxide of Sr, Bi and Ta is used as a coating liquid.
