Title: Outboard ramp
Inventor: SEKIGUCHI GOICHI
IPC: B63B27/14
Filed: 1985-10-24
Abstract: PURPOSE:To decrease the refraction angle per fulcrum and expand the usable range of a ramp without affecting the car passage by dividing the first panel of an outboard ramp into the hull side and the quay side and rotataby connecting them within a predetermined range. CONSTITUTION:The first panel 1 of an outboard ramp is divided into a panel A on the hull side and a panel B on the quay side, and they are rotatably connected within a predetermined range at a fulcrum 7. Then, the panel A is not rotated by a fixed amount or more due to a stopper 6, and the refraction angle of the fulcrum 7 is kept at a fixed amount or less by the stopper. Therefore, since the panel B is inclined to the maximum limit of the inclination angle at any position in the upper and lower limits of a hatch 4 allowing the use of the ramp, the ramp can cope with the difference in level between the hatch 4 and quay in a wide range. The refraction angle per fulcrum is decreased, the panel refraction at the fulcrum does not affect the car passage, and the usable range of the ramp is expanded.

Title: Circuit for detecting deterioration of laser diode
Inventor: TAKAMATSU YOKO
IPC: H01S5/042
Filed: 1995-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a circuit for detecting deterioration of a laser diode even when the output therefrom is not controlled constantly. SOLUTION: An LD current detection circuit 13 detects the voltage value corresponding to an LD current ILD while a PD current detection circuit 14 detects the voltage value corresponding to a PD current IPD. An increase rate of PD current detection value is initially set to be equal to that of LD current detection value. When a differential amplifier 15 takes a relative difference to the LD current ILD under that state, the PD output has the relative value of threshold current Ith which is invariant regardless of variation in the LD current ILD. When the LD deteriorates with that setting, the threshold current Ith increases to cause increase of output from the differential amplifier 15. A comparator 16 detects an output from the differential amplifier 15 exceeding a reference level and makes a decision that the LD has deteriorated before delivering an alarm.

Moreover, the density of the green sheet 1 is made 1.55-1.65g/cm<3>. At the time of the lamination bonding by thermocompression, the green sheet is deformed, whereby the collapse of inner layer wiring can be suppressed to the utmost, and besides the dispersion of the shrinkage factor of a board after sintering can be made small.
