Title: Semiconductor device
Inventor: UNO TOMOAKI
IPC: H01S3/109
Filed: 1987-05-12
Abstract: PURPOSE:To obtain a short wavelength light stably, efficiently and moreover, easily without adjusting by a method wherein a layer consisting of nonlinear optical materials capable of generating light of a secondary high frequency is provided on the main surface of a substrate, is placed in the interior of a laser resonator and reflecting layers having a high reflectivity to a laser beam and having a low reflectivity to the secondary high frequency are placed on the layer. CONSTITUTION:A semiconductor laser structure is constituted of an AlGaAs material grown epitaxially on a p-type III-V GaAs compound semiconductor substrate 3 and nonlinear optical materials 5-8 (a p-type AlGaAs layer, an n-type AlGaAs layer, a p-type AlGaAs layer and an n-type AlGaAs layer) to generate a secondary high frequency consist of a ZnSSe II-VI compound semiconductor layer 10 grown epitaxially on the AlGaAs material. When a current is flowed toward an electrode 9 from an electrode 1, the current is luminesced in a GaAs active layer 12 and a laser oscillation of a wavelength of 0.82mum is generated between reflecting layers 11 having a high reflectivity. Light of the wavelength of 0.41mum of the secondary high frequency of a laser beam is generated in the layer 10 and is taken out to the exterior via the reflecting layers 11 having a low reflectivity as a secondary high-frequency output 14.

Title: Vehicle navigation apparatus and automobile
Inventor: HONEY STANLEY K
IPC: G09B29/00
Filed: 1997-04-18
Abstract: PROBLEM TO BE SOLVED: To achieve a higher vehicle tracking accuracy by a method wherein a position with a higher existing probability than that of the current estimated position to correct the current location but updating is omitted when such an operation is not required. SOLUTION: A computer 12 utilizes distance and bearing data, a map data base stored in a memory medium 14, information on the accuracy of an estimated position DRP to generate one parameter or more. These parameters are useful for determining whether the segment S with the highest probability exists or not and moreover, whether such a segment S contains the DRPcu with the existing probability higher than that of the current estimated position DRPc. When such a segment S is determined to exist, the computer 12 calculates a position with a higher probability to update the DRPc to the DRPcu and further performs an evaluation of the accuracy of the DRP and a calculation of a calibration coefficient. The computer 12 selectively processes the information obtained to accomplish an updating according to a vehicle navigation algorithm.

Title: Alkaline storage battery
Inventor: ICHIBA MASAO
IPC: H01M10/34
Filed: 1986-05-20
Abstract: PURPOSE:To make it possible to effectively retard hydrogen gas evolution from a cadmium anode by arranging a cadmium anode and using an alkaline electrolyte containing antimony trioxide. CONSTITUTION:Potassium hydroxide solution is used as an alkaline electrolyte, and antimony trioxide is added to the solution. The antimony trioxide is dissolved in the solution and potassium antimonite is produced in the solution. Since potassium antimonite has strong reducing capability, when the electrolyte containing the potassium is poured, cadmium hydroxide in a cadmium anode is reduced and active metallic cadmium is deposited in the anode. The metallic cadmium serves as conductive material and charge of the cadmium anode is uniformly advanced. overvoltage in the anode is decreased even in quick discharge or charge at low temperature, and hydrogen gas evolution is effectively retarded.

Title: Speaker
Inventor: INANAGA KIYOFUMI
IPC: H04R9/04
Filed: 1988-05-13
Abstract: PURPOSE:To flatten a frequency characteristic and to make sensitivity satisfactory by forming a diaphragm and a conducting part with a high polymer material having conductivity. CONSTITUTION:When an a.c. current as a sound signal is applied to a primary feeding coil 3, a.c. magnetic flux corresponding to an input waveform is generated. Since a ring conducting part 8 has satisfactory conductivity and is closely interlinked with the a.c. magnetic flux, an induced current having the same frequency as that of the a.c. current is induced in the conducting part 8 by a mutual inducing phenomenon. Since the conducting part 8 is positioned in a magnetic cavity 10, force proportional to the product of the intensity of a d.c. magnetic field in the magnetic cavity part 10 and the induced current is acted on the conducting part 8. Namely, the induced current of the conducting part 8 interacts with the d.c. magnetic field in the magnetic cavity part 10, drives a diaphragm 2, and radiates a sound wave. Since the diaphragm 2 composed of a high polymer film having the conductivity has a comparatively large mechanical loss and light weight, in never generates a resonance peak in the frequency characteristic, and the frequency characteristic of a speaker 1 can be flattened.

Title: Lens driving device using bimorph driving element
Inventor: TANAKA YOSHIHIRO
IPC: G03B13/34
Filed: 1987-05-12
Abstract: PURPOSE:To make it possible to drive a member to be driven to a desired position and to return the member to the original position by discontinuously driving a bimorph driving element to cause vibration in a prescribed amplitude or vibration exceeding the prescribed amplitude and to repeat the vibration. CONSTITUTION:This lens driving device is provided with a spring 32 for pressing a cam ring 29 to the original position and a stop lever 33 engaged with one of the ratchet pawls 29b of the ring 29 and pressed to a position at which the return of the ring 29 to the original position is hindered. A bimorph driving element Bi2 is controlled so as to cause small vibration having a small amplitude and large vibration having a large amplitude in the counterclockwise direction. When small vibration is caused once, a sending pawl lever 31 sends the pawls 29b by one tooth. When large vibration is caused, the tip of the lever 31 moves the stop lever 33 against the pressing force to a position at which the lever 33 is disengaged from one of the pawls 29b, so the cam ring 29 is returned to the original position by the pressing force of the spring 32.
