Title: Vehicle approach sensing alarm device
Inventor: OBA YUKIO
IPC: G08G1/16
Filed: 1993-04-09
Abstract: PURPOSE:To effectively prevent a sudden collision accident between an opposed vehicle which turns to the right and an approaching rear vehicle. CONSTITUTION:A vehicle A detects its own speed, a motorcycle C which approaches from the rear side, and an opposed vehicle B which crosses in front of the vehicle A. When the vehicle A detects the motorcycle C and the opposed vehicle B while stopping or going most slowly, alarming such as lighting of an alarm lamp is carried out for drivers in/on the opposed vehicle B, the motorcycle C and the vehicle A. It is thus possible for the driver in the opposed vehicle B to grasp the existence of the motorcycle C and for the driver on the motorcycle C to grasp the existence of the opposed vehicle B for the effective prevention of a sudden collision accident between both.

Filed: 1986-04-11
Abstract: PURPOSE:To improve shading in a scanning-line perpendicular direction by providing a ROM which stores correcting values of shading of scanning lines corresponding to counted values of a scanning line counter and an adder which adds the output of an A/D conversion part and the output of the ROM together to perform shading correction. CONSTITUTION:The ROM 8 is stored with the correcting values proportional to vertical positions of scanning lines specified previously by the scanning line counter 5 and a correcting value is outputted according to the indication of the scanning counter 5. The output of the A/D conversion part 2 obtained by converting the video analog signal of a television camera 1 having shading characteristics attenuating linearly in the scanning-line perpendicular direction into a digital signal is added by the adder 7 to the correction output corresponding to the scanning line perpendicular position of the ROM 8 and the sum is inputted to an image memory 8. Consequently, the shading characteristics in the scanning-line perpendicular direction are improved.

Title: Leader supporter for pile driving device
Inventor: SAKAI TOSHIKI
IPC: E02D7/16
Filed: 1980-06-23
Abstract: PURPOSE: To provide a stable leader which prevents the creation of twist of a stay against an upper leader, by a method wherein a boxform stopper and the bracket of the stay restrict the rotation of the stay of the leader.  
     CONSTITUTION: During the operations to drive a pile by means of a hammer 31, a lower leader 24 and an upper leader 27 are coupled by means of a pin to keep the upper leader 27 from spinning. When hole-boring is completed and a hammering work follows, the pin is removed to drive a hydraulic driving device 28. When the upper leader turns by 90°, the rotary repulsion, produced due to a difference in weight between the hammer 31 and an auger, causes rotating of a stay-fitting member 33, and thereby stays 34 and 35 are restricted to turn by means of stopper pims 44 and 45 of a boxform stopper 40 and brackets 34A and 35A at the stays 34 and 35.

Abstract: PURPOSE:To prevent the uneven thickness and quality deterioration by performing traction and intermittent traction with the end part of non-insertion side of a thin film tube as the turn of an elongated hose comes to the curved part of a laid pipe, and making the elongated hose to be turned and inserted thereinto while the thin film tube being strained. CONSTITUTION:Upon the turning and inserting operation of an elongated hose 20, the end part of non-insertion side of a thin film tube 21 is performed with traction and intermittent traction as the turn of the hose 20 comes to the curved part 6a of a laid pipe 6, and the turning and inserting operation of the elongated hose is performed while the thin film tube 21 being strained. Thus, the hose 20 passes readily through the curved part 6a of the laid pipe 6 which has been turned and advanced within the thin film tube 21. In this manner, as the thin film tube 20 is turned and inserted into the laid pipe and the thermoplastic resin of the hose 20 is heated and cured, the tube 21 is disposed over the range of the laid pipe 6 and the cured hose 20. As a result, the thermoplastic resin under heating and curing becomes a low viscosity and never oozes out of the dislocation of joining part of the pipe 6 or the gap of a crack.

Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a long write/erase life and enable the reduction of the erase voltage, by forming many columnar protrusions on a floating gate, and flowing a tunnel current from the top end of the protrusion to erase information. SOLUTION: A plurality of columnar protrusions 3b are formed on the top face of a floating gate 5, and protrusions 3c are formed on the columnar protrusions 3b tops. The tops of the protrusions 3c locate near a control gate 8 and hence an electric field concentration occurs to flow a Fowler- Nordheim(FN) tunnel current, thereby erasing information. Since the many columnar protrusions 3b are formed on the top face of the floating gate 5, the write and erase of information are repeated and the FN tunnel current flows from other columnar protrusion 3b, if a tunnel insulation film 6 covering one columnar protrusion 3b deteriorates to make the FN tunnel current hard to flow.
