Title: Traveling method of vehicle having supper structure and lower structure
Inventor: FUJIKI AKIYOSHI
IPC: E02F9/22
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To reduce the accident by operating a directional control vale by a turning position judgment device, when an supper structure turns in a fixed range or more, and switching the instruction from a traveling lever from forward to backward or from backward to forward or canceling it, and transmitting the resulting instruction to a traveling wheel. SOLUTION: When an upper structure is turned, a turning position detecting device 11 detects the position and transmits the information to a turning position judgment device 12, which then operates a directional control valve 13 when the turning in a fixed range or more is judged. When an instruction of traveling stop is received the flow of oil from a traveling lever 5 to a traveling wheel is interrupted by the control valve 13 to cancel the operation of the lever 5. When the reverse of the oil flow is instructed, the control valve 13 carries the oil carried in the forward circuit from the lever 5 to the backward circuit, or carries the oil carried in the backward circuit to the forward circuit. The oil passed through the directional control valve 13 is passed in a swivel joint 8 and carried to the traveling motor 9 of the traveling wheel to move the machine.  The operating direction of the lever 5 is conformed to the moving direction of the vehicle to reduce the accident.

Title: Preventing method of meandering of tall end part of rolled stock
Inventor: YOSHIMURA HIROYUKI
IPC: B21B39/14
Filed: 1990-05-09
Abstract: PURPOSE:To prevent the generation of reduction and to improve working rate and yield by keeping the vertical clearance of entry guides with which a rolled stock is held approximately equally to the thickness of the rolled stock until the tail end part of the rolled stock is finished to pass through the entry guide part which is provided on the inlet side of a tandem type rolling mill. CONSTITUTION:Because this rolled stock is kept in the state that the rolled stock is passably inserted and held by approximately equal clearance to the thickness with right and left entry guides 6a until the tail end part la of the rolled stock 1 is finished to pass through the entry guide part 6a, phenomena that the tail end part is brought into contact with the guideway of the entry guides 6a and that the end part in the width direction of the tail end part is climbed the guideway, etc., are not generated. And, because the clearance is reduced according to the thickness even if the rolled stock 1 is thinned, reduc tion or the like that is conventionally more liable to be generated as the thick ness is thinner can't be generated.

Title: Temporary contamination preventing method of joining part of caisson element
Inventor: KASUYA MAKOTO
IPC: E02D29/063
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To form a coating film for preventing contamination on a rubber gasket in the joining part of a caisson element used for submerged tunnel construction method so that the coating film is applied with each workability and maintains contamination- preventing property for a specified period in sea water and that when the joining parts are joined, the coating film can be peeled without damaging the rubber surface. SOLUTION: A silicone-based contamination-preventing film is formed on the outside surface of a rubber gasket and the coating film is peeled just before the joining parts of the elements are joined. First, the coating film for preventing contamination is formed by laminating an atoxic contamination preventing adhesive sheet on the outside surface of a rubber gasket. The adhesive sheet has such a structure that an adhesive layer, a base sheet layer, a silicone primer layer and a hardened coating film of a reaction-hardening type silicone resin-contg. coating material for preventing contamination are successively in this order formed on a releasable sheet. When the coating film is peeled, the laminated sheet is peeled from the adhesive layer. In a second example, the contamination-preventing film is formed on a strippable coating film formed on the outside surface of the gasket.

Title: Logical circuit
Inventor: TAKAI ATSUSHI
IPC: H03K19/0952
Filed: 1983-06-30
Abstract: PURPOSE:To attain a high yield by using a circuit connecting a constant current circuit and a diode in parallel as a load to reduce the area of the load for circuit integration, attain high-speed operation and low power consumption and reduce variation. CONSTITUTION:When an FET1 is turned on, a diode 5 is turned on, and a current therethrough is superimposed on a current of a constant current circuit 13. The rate of increase in the current value to a potential difference between diodes 5 and 6 is extremely high, a large current flows to a load whose output voltage reaches a low level and a minimum constant current only flows to a load whose output voltage reaches at a high level. Thus, the output voltage is made stable, high speed is attained by the constant current load, and since an FET is used for the constant current circuit, the area is made small in case of circuit integration and the yeild is kept high by using the FET and the diodes without variation.
