  • Patent number: 4931340
    Abstract: A honeycomb panel structure for thermal and acoustic insulation and for load bearing capability has a honeycomb panel which comprises a honeycomb core laminated with two facing plates, and a pair of housings. Each housing has a channel to engage and support a edge of the honeycomb panel. A first neutral axis passes through the center of gravity of the honeycomb panel and extends in the direction of the panel. A second neutral axis passes through the centers of gravity of the housings and extends parallel to the first neutral axis. The first and second neutral axes are spaced apart in a vertical direction so that the structure has much higher flexural rigidity.

  • Patent number: 4912322
    Abstract: An optical type displacement detecting device including a main scale and an index scale, wherein a pitch of a first optical grating formed on the main scale is set at P and a pitch of a second optical grating formed on the index scale is set at P/n, thereby producing divided detection signal having pitch P/n. Furthermore, the pitch of the second optical grating is set at (u+v) P/u or (u+v) P/(2u) (u is a gap between a diffusive light source and the first optical grating and v is a gap between the first and second optical gratings), so that a collimator lens can be dispensed with. Further, higher harmonic components of the first optical grating are utilized, whereby the pitch of the second optical grating is set at substantially (u+v) Q/u or (u+v) Q/(2u) (Q=P/m, and m is a whole number of 2 or more), thereby preventing the pitch of the second optical grating from being divided into small ones.

  • Patent number: 4869528
    Abstract: An electronically controlled fluid suspension system for preventing the lateral roll of a vehicle computes a predetermined estimated lateral acceleration based on the running speed and the difference between the maximum steering angle and the minimum steering angle within a predetermined period. The supply and discharge of the air to and from the air springs is rapidly controlled corresponding to the estimated lateral acceleration so as to prevent the vehicle from rolling due to the steering operation. Moreover, the electronically controlled fluid suspension system computes a predetermined target vehicle height based on the lateral acceleration. After the air is supplied and discharged to and from the air springs and the increase of the lateral acceleration is stopped, the vehicle height is restored regardless of the external disturbance, by controlling the supply and discharge of the air corresponding to the vehicle height difference between the target vehicle height and the actual vehicle height.
