Title: Loudspeaker system
Inventor: TAGAMI AKIRA
IPC: H04R1/34
Filed: 1992-05-27
Abstract: PURPOSE:To obtain a loudspeaker system in which the resonance of tube is hardly generated by forming the shape of an acoustic tube in the shape whose cross-sectional area is gradually enlarged toward both opening parts. CONSTITUTION:An acoustic tube 2 is attached to a loudspeaker unit 1. An acoustic tube input part 3 is formed at the fitting part, and an acoustic tube output part 4 is formed at the opposite part. The acoustic tube 2 is formed as that the center part is thinned. That is, the center part is formed in a shape in which the cross-sectional area is enlarged gradually toward the direction of both opening parts of the acoustic tube input part 3 and the acoustic tube output part 4 from the center part as an origin 5 for enlarging the cross-sectional area. A variation of the cross-sectional area from the origin 5 is proportional to a square of a distance. Also, in a joined part of the loudspeaker unit 1 and the acoustic tube 2, a small opening part 6 is provided. In such a way, an acoustic impedance of the tube is not varied suddenly, and thereby a reflection of a sound in the acoustic tube output part 4 caused by resonance of the tube hardly occurs.

Title: Vehicle control system
Inventor: NOMURA HAJIME
IPC: F02D45/00
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle control system that is capable of requiring, when a vehicle breaks down, the driver to inspect or repair it rapidly. SOLUTION: It is determined in S200 whether DIST exceeds a first criterion value A, or whether to effect a third-stage process against a serious malfunction. If S200 ends in the affirmative, the third-stage serious-malfunction process as a strong warning cuts off fuel in S230 to hold the engine speed falling below a constant value. It is determined in S210 whether DUST exceeds a second criterion value B, or whether to carry out a second-stage process against a slight malfunction. If S210 ends in the affirmative, the second-stage slight- malfunction process as a light warning stops the operation of the air conditioner in S240. It is determined in S220 whether DUST exceeds a third criterion value of zero, or whether to trigger a first-stage process. If S220 ends in the negative, the first-stage process actuates the alarm lamp to indicate the abnormality in S250.

Title: Inner mirror
Inventor: UMEDA FUMIO
IPC: B60R11/02
Filed: 1996-05-29
Abstract: PROBLEM TO BE SOLVED: To secure a wide operation area of a receiver without hindering the design of appearance by providing an antenna for receiving the electric wave, which is sent from a transmitter of a remote control device provided in a vehicle inside of a housing. SOLUTION: An antenna 18 is formed of a reflecting film 10, a first and a second supporting members 12, 13. A grounded conductor layer 14 on a circuit board 8, to which the second supporting member 13 is connected, functions as a ground plate in relation to the antenna 18. This antenna 18 and a receiver circuit 7 form a receiver of a remote control device. The antenna 18 receives the transmitted electric wave, and supplies the receiving signal to the receiver circuit 7, which is formed of various electronic parts, through a first connecting point N1. Since the antenna 18 of the receiver is provided inside of an inner mirror, the influence of the electromagnetic shield effect does not work to the electric wave from the transmitter, and the receiving sensitivity of the antenna 18 is remarkably improved.
