IPC: H01R13/53
Filed: 1993-05-24
Abstract: PURPOSE: To provide an electric connector, which has the simple and microscopic constitution and is superior in an arc-extinguishing function. CONSTITUTION: A connector 10 is composed of separable connecting electrodes 12 and 14, and a member 44 is formed as a structure to be engaged with one electrode 14 through a spring-loaded drive cap 24 having grounding electric potential.

IPC: B60T8/96
Filed: 1994-07-11
Abstract: PURPOSE:To prevent unproper antilock control from being performed to the last and resolve the problem of a reduction of steering stability by completing the antilock control in the middle when an abnormality occurs on the power voltage during the antilock control. CONSTITUTION:An antilock control unit 80 receives the detection signal of a power voltage detecting device 112 and judges whether the battery voltage is abnormal or not during the travel of a vehicle. When it judges that the battery voltage is abnormal, it judges whether antilock control is under way or not depending on whether any of four antilock control flags is set or not. When antilock control is under way, it judges whether the estimated vehicle body speed is a set value (control termination speed for terminating the antilock control when an abnormality occurs on the power voltage) or below or not. When the vehicle body speed becomes the set value or below while the step-on of a brake pedal 10 is not released, a warning lamp 124 is lighted, and the antilock control is terminated.

Filed: 1980-11-12
Abstract: PURPOSE:To obtain a cold electrode gas laser tube with a narrow tube free from bending and having an excellent accuracy in an inner diameter by a method wherein a coaxial duplex structure of thin narrow tubes is adopted. CONSTITUTION:A tube of inner diameter around 4.02+ or -0<0.05>mm. and of thickness around 1.5+ or -mm. is used as an outer narrow tube, and a tube of inner diameter around 1.2+ or -0.02mm. and of thickness around 1.4+ or -0.05<0> is used as an inner narrow tube. By managing a manufacturing process of a narrow tube, a narrow tube of inner diameter around 1.2+ or -0.02mm. can be obtained without selecting it referring to inner diameters and with a low price. When these narrow tube is disposed in coaxial duplex structure, by a region within an inner diameter d of the inner narrow tube 2 excited into an active region of a laser and functioning as a narrow tube where a laser plasma is generated, a bending is prevented by an outer narrow tube 1 supporting an inner narrow tube 2 with an equal effect of using a thick narrow tube. Accordingly dispersion of a laser output and a potential drop in a tube is small, and a gas laser tube with a stable output and low price can be obtained.

Title: Optical receptacle
Inventor: ISHIDA CHISAKO
IPC: G02B6/42
Filed: 1997-06-03
Abstract: PROBLEM TO BE SOLVED: To reduce a transmission loss in an optical signal and to miniaturize it by press feeding a hold ring through the outside of an elastic sleeve inserted with an incorporated ferule and restricting free deformation in the inserted part of the elastic sleeve. SOLUTION: An optical receptacle 1 is provided with the elastic sleeve 15 of a long hollow cylindrical shape. The incorporated ferrule 17 is inserted into the base end side of the inner hole 15a of the elastic sleeve 15, and the elastic sleeve 15 is integrated with the incorporated ferrule 17 by press feeding. The hold ring 13 is inserted into the outer periphery of the base end part of the elastic sleeve 15 by the press feeding. This hold ring 13 controls the elastic elongation/contraction of the base end part of the elastic sleeve 15, and holds the elastic sleeve 15 in a sleeve case 11. Since an insertion length L1 of a plug ferule 3 is longer than L2, the tilt of the plug ferrule 3 for the optical receptacle 1 is reduced, and since end surface between an optical fiber 4 and the optical fiber 19 is kept tightly, the transmission of the optical signal is stabilized.
