Filed: 1986-12-24
Abstract: PURPOSE:To enable perfect stoppage of machine body upon releasing of foot from a speed change pedal, by providing a lock mechanism interlocked to operate a hydraulic pump shaft through back/forth rotation of a speed change pedal and block the rotation at a neutral position. CONSTITUTION:When a speed change pedal is placed 3 at a neutral position, a neutral recess in a neutral lock cam 10 matches with a spool 21 and a shortcircuit path section thereof shortcircuits a delivery port 23a and a return port 24a of a hydraulic pump so as to reduce the pressure to zero thus stopping the rotation of a hydraulic motor completely. When an operator releases his foot from the speed change pedal 3, a neutral energizing arm 4 pushes an engaging pin 7 of a stop pin arm 6 and moves the pin 7 to the neutral position so as to bring the speed change pedal 3 and a HST speed change device H automatically to the neutral position thus shortcircuiting by means of a neutral lock valve A. Consequently, the speed change device H is brought into perfectly stopped state and safe state can be achieved.

Title: Illumination method for automobile road tunnel
Inventor: TSUKASAKI FUMIO
IPC: F21S8/02
Filed: 1998-09-29
Abstract: PROBLEM TO BE SOLVED: To increase the quantity of obstacle viewing information for a driver to contribute to the avoidance of an accident and to reduce consumption power by arranging illumination lamps on the upper part of a wall surface or a ceiling part in a tunnel at appropriate intervals, by reducing the magnitude of an irradiation solid angle as much as possible by concentrating it on an irradiation object, and by utilizing superimposed irradiation by the use of the multiple illumination lamps by tilting an irradiation optical axis forward. SOLUTION: When an irradiation solid angle and a tilt angle of an optical axis are set to 70 deg. and 45 deg., respectively, irradiation light from seven illumination lamps in irradiation solid angle ranges L1-L7 impinges on an obstacle 1 located in one illumination area. When the irradiation is tilted forward and downward like this, the projected area on a road face from the respective lamps is expanded, and irradiated in a superimposing form without discontinuation, so that the irradiation solid angle can be reduced and the irradiation luminous intensity can thereby be enhanced. As the irradiation solid angle is set smaller, larger luminous intensity is provided, and the irradiation solid angle is set in a range where the tilt angle is effective.  The maximum value of the irradiation angle (the sum of the tilt angle and a half of the irradiation solid angle) is around 85 deg. when considering the prevention of glare to a preceding vehicle.

IPC: H04N1/04
Filed: 1987-12-11
Abstract: PURPOSE:To improve the recognition rate by setting the reference points of arbitrary number of pieces each to the upper and the lower parts, and the right and the left of a drawing, calculating in which square surrounded by the reference points a recognition start point position exists and calculating the recognition start point position by regarding the expansion and contraction as uniform in the square.

When the square has been determined, a ratio related to where the recognition start point position is positioned in the square on the normal drawing is derived. By this ratio, a position in the square on an input drawing, which is considered to expand and contract uniformly is calculated. By adding a position of the square to said position, the recognition start point position where an error is scarcely generated is derived.
