Title: Chain lever hoist
Inventor: WADA YASUO
IPC: B66D3/14
Filed: 1998-12-02
Abstract: PROBLEM TO BE SOLVED: To provide a chain lever hoist capable of securing stable loose rotating operation for a long period of time by a simple design. SOLUTION: An operation lever 22 is supported free to revolve in a state with a specified interval from a first hub 55 on an opening part 76 of a brake cover 77 on a chain lever hoist which comes to be in a loose rotating state as it is when the no load side of a load chain 33 is drawn or an operation handle 59 is rotated in the reversing direction under certain circumstances by positioning an engagement click 80 at a neutral position which is not engaged with the normal direction and the opposite direction against an engagement tooth 56 by operation of a change-over lever 86. Consequently, as the first hub 55 is rotated together with a drive shaft 37 without making contact with the operation lever 22 at the time of loose rotating operation, it is possible to perform certain loose rotating operation.

Title: Solenoid valve controller in hydraulic circuit of industrial vehicle
Inventor: YAMADA TADASHI
IPC: B66F9/24
Filed: 1997-12-12
Abstract: PROBLEM TO BE SOLVED: To simplify a circuit (hardware) required in the light of feedback control over a current value flowing into the solenoid of a solenoid valve. SOLUTION: A central processing unit 54 controls the current value of a solenoid valve installed in a hydraulic circuit of a forklift truck. In this case, a pulse width modulation signal conformed to the duty output value commanded by this CPU 54 is outputted from a pulse width modulation port 59. A transistor 60 connected in space between a battery and a solenoid 25a exercises its on-off operation on the basis of the pulse width modulation signal. The current flowed into the solenoid 25a is detected by a current detection circuit 52, and a detection signal (current detected value) S2 passed through a low-pass filter 53 is inputted into an analog-to-digital port 62. The CPU 54 executes current value controlling program data in succession, comparing the current detected value with the prestored desired current value, and thus it is made so as to compensate the duty output value so as to have both the values accorded with each other within the allowable range.
