Title: Four-wheel steering control device
Inventor: MINAZU KIYOAKI
IPC: B62D7/14
Filed: 1990-04-05
Abstract: PURPOSE:To satisfactorily maintain the steering property at the time of reverse running by automatically switching the steering mode to the reverse-phase four-wheel steering mode for a turn with the minimum turning radius when a working machine is lifted, and automatically switching the steering mode to the rear wheel steering mode when a forward/reverse transfer lever is shifted to the reverse position. CONSTITUTION:A lift position detecting sensor 32 transmits a signal to a CPU when a hydraulic lever 31 is set on, and a controller detects that a ground working machine is in the lift position state. A shift position detecting sensor 34 transmits a signal to the CPU when a forward/reverse transfer lever 33 is shifted to the reverse position, and the controller detects that a vehicle is in the reverse running state. A steering mode transfer switch switches the steering mode to an optional mode among modes 1-4, and a signal indicating which mode is selected is transmitted to the CPU via an input interface. The reverse- phase four-wheel steering mode is selected when the working machine is in the lift position. The rear-wheel steering mode is preferentially selected when the forward/reverse transfer lever 33 is in the reverse running position.

Filed: 1999-03-31
Abstract: PROBLEM TO BE SOLVED: To obtain an oil supply tank in which a cap can be removed easily from the fuel intake of a cartridge tank without contaminating fingers with kerosene by coupling an elevating/lowering guide tube with the fuel intake cap through bending of stop clips. SOLUTION: Eight stop clips 19, 19, for example, are provided at the lower end of an elevating/lowering guide tube 13. Rectangular holes 20 are made at the stretching base part of a spring receiving seat provided at the lower end of a fuel intake cap 3 and inserted, respectively, with two stop clips 19, 19. The stop clips 19, 19 are bent after being inserted into the rectangular holes 20 and jointed rigidly to the fuel intake cap 3. The elevating/lowering guide tube 13 and the fuel intake cap 3 are separated by recovering the stop clip 19 from bent state. A knob handle can thereby be replaced easily by a new one upon damage. In other words, the elevating/lowering guide tube 13 is fixed to the fuel intake cap 3 not by welding but by means of the stop clip 19.

Title: Continuous bright annealing method for titanium coil material
Inventor: KOJIMA TOSHIO
IPC: C22F1/00
Filed: 1987-04-16
Abstract: PURPOSE:To produce a bright annealed titanium sheet material having high quality without being formed with temper colors, etc., continuously with high efficiency by setting the atmospheric pressure of gaseous N2 atmosphere chambers at the pressure lower than the gaseous Ar atmosphere pressure in a furnace body and higher than the out-of-furnace pressure. CONSTITUTION:The atmospheric pressure of the gaseous N2 atmosphere chambers 11, 11' of the continuous bright annealing furnace body 10 is set higher than the out-of-furnace pressure 10 and the gaseous Ar atmosphere pressure in the furnace body 10 is set slightly higher than the atmospheric pressure of the gaseous N2 atmosphere chambers 11, 11'. The pressure to press a coil 3 to be treated to felt 12 is so regulated that some gaseous N2 is ejected from the felt seal in the inlet side chamber 11 to the outside of the furnace 10. The surface of the coil material 3 is cleaned by the ejection flow of such gaseous N2. The O2 sticking to the coil material 3, is therefore, not carried into the furnace body 10 and the generation of the temper colors is prevented. An infiltration accident of the gaseous N2 into the furnace body 10 is prevented even if the pressure in the chambers 11, 11' increases.
