Abstract: PROBLEM TO BE SOLVED: To improve energy density and cycle life when a carbon material and a composite material are used as a negative electrode by operating the negative electrode in a specific range of current density by setting its capacity higher than a logical capacity of the negative material and lower than a capacity of lithium metal. SOLUTION: Operating current density of a negative electrode is set 0.4-8.0 mA/cm2. For example, in the case of using a negative electrode mixture containing a mixture of highly purified natural graphite with furnace black and a binding agent, discharge capacity hardly decreases after a given cycle test at a defined charge capacity. Thickness of the negative electrode and negative electrode mixture layer is 0.1-100 μm, the thickness ratio of the negative electrode to a positive electrode mixture layer is 1/10-1/2, and density of the negative electrode mixture layer is 0.5-8.0 g/cm3. An active material used for the positive electrode is LiXO2 or LiX2O4 (where, X is a transition metal such as Co, Ni, Mn or the like, or part of it is replaced by Al or alkaline earth metal such as Mg).  An electrolyte layer holding electrolyte and electrolytic solution in polymer such as ethylene oxide is suitable.

Abstract: PURPOSE:To improve the identifying ability of a running vehicle to be measured and to suppress the intercept of transmission by performing optical transmission and reception of a narrow beam by using optical modulated signals and displaying a vehicle speed after finding the speed from the reflected light producing timing of the vehicle and distance between detecting sections. CONSTITUTION:Detecting sections 2a and 2b separated from each other by a distance R respectively send optical modulated rays of light received from an optical modulating section 1 over a road in directions (vertical direction) in parallel with each other as transmitting rays of light at a prescribed light transmitting field angle theta1. Light receiving sections 22a and 22b are set in standby states in symmetrical directions l2 and l3 at the same light receiving field angle theta2 so that they can catch the reflected rays of light of the rays of light sent from the detecting section reflected by a running vehicle in the same state. The reflected rays of light from the running vehicle are successively caught by means of the receivers 22a and 22b in a range where the field angles theta1 and theta2 overlaps and outputted after photoelectric conversion and amplification. A speed calculating section 4 calculates the running speed of the vehicle based on the emitting timing of the emitted rays of light and the distance R and a speed displaying section 5 displays the speed data in accordance with a prescribed displaying form.

Abstract: PROBLEM TO BE SOLVED: To prevent a motor operation from being hindered even in the malfunction of an auxiliary relay and provide excellent operation reliability by connecting a self-auxiliary switch contact in series to an auxiliary relay contact within a motor operating circuit. SOLUTION: In the middle of ON-operation of a motor operating circuit, ON-side motor operating auxiliary relay contacts 24, 25 and self-auxiliary switch contacts 33 (B11), 33 (B12) are closed, and OFF-side motor operating auxiliary relay contacts 30, 30 and self-auxiliary switch contacts 33, 34 are opened. Even if the auxiliary relay contacts 30, 30 are erroneously made by the excessive operating vibration of a drive spring, the self-auxiliary switch contacts 33 (A11), 33 (A12) is kept open. Thus, since the self-auxiliary switch contacts 33, 34 are opened even if the auxiliary relay contacts 24, 24, 30, 30 are made, formation of a short-circuiting circuit without through a motor 25 can be prevented, and the ON-operation can be continued.
