Title: Lithium secondary battery
Inventor: MORITA TERUYOSHI
IPC: H01M10/0569
Filed: 1990-05-02
Abstract: PURPOSE:To provide a lithium secondary battery which exhibits excellent characteristics by using carbon, an organic polymer, an inorganic compound, etc., in a negative electrode and using organic solvent under conditions that existence of lithium as metal in a battery is not allowed. CONSTITUTION:A composite oxide containing lithium is made to be a positive electrode, and a substance which occludes lithium at the time of charging and emits lithium at the time of discharging is made to be a negative electrode, while a single organic solvent which gently reacts with lithium or organic electrolyte wherein inorganic salt is added to a mixture of said organic solvent and an organic solvent which rarely reacts with lithium is used. As the electrolyte, a mixture of propylene carbonate and ethylene carbonate with a volume ratio of 1:1 with LiPF6 solved at a rate of 1mol/l is used. This constitution allows the organic solvent which reacts with lithium to be used as electrolyte even when an organic polymer such as polyacetylene or an inorganic compound such as iron oxide is used in the negative electrode, and also good charge/ discharge cycle characteristics can be exhibited.

Title: Vehicle speed control device
Inventor: NISHIMURA EIJI
IPC: B60W30/00
Filed: 1993-05-19
Abstract: PURPOSE:To eliminate the fluctuation of a target vehicle speed by stopping the speed control of a vehicle and holding the value of a control variable on the basis of a distance to a preceding vehicle, when the preceding vehicle is no longer detected, in controlling the speed of the vehicle on the basis of the distance to the preceding vehicle. CONSTITUTION:An auto-cruising system detects a distance between a preceding vehicle and a vehicle with a distance sensor 10, and further detects the speed of the vehicle with a speed sensor 51. Also, an engine 40 is controlled with a control unit 20, on the basis of signals detected with sensors 10 and 51, and an output signal from an operation device group 60. In this case, the control unit 20 performs arithmetic operation about a control variable according to the prescribed process, on the basis of the detected distance to the preceding vehicle, and holds a distance to the vehicle at the preset target value, depending upon the resulting control variable. On the other hand, the sensor 10 estimates possibility to catch up with the preceding vehicle. As a result, when the preceding vehicle can be no longer detected, auto-cruising mode is stopped and, at the same time, the value of the control variable is maintained.

Title: Position detector for movable part
Inventor: HAMANAKA YUMIKO
IPC: G11B7/09
Filed: 1987-05-15
Abstract: PURPOSE:To eliminate a position error in a focus direction which is caused by the rolling mode of the movable part of an optical driving device by providing plural detecting means and performing position detection according to the sum of individual detection signals. CONSTITUTION:A mirror and two sets of position detectors consisting of photoreflectors 16a and 17a, and 16b and 17b are provided at right angles to the moving direction of the movable part 5 which moves an objective in the optical-axis direction for focusing. The sum of the detection outputs of those position detectors is calculated and then when the movable part 5 rolls, one position detector moves away as much as the other approaches, so the detection output sum is not affected by the rolling. Consequently, the detection position error in the focus direction which is caused by the rolling mode of the movable part can be eliminated. Similarly, a position detection error in a tracking direction which is caused by focus-direction displacement is also eliminated.
