Title: Forklift
Inventor: OHASHI SABURO
IPC: B66F9/22
Filed: 1989-03-15
Abstract: PURPOSE:To safely operate the title forklift with one operator by installing a remote-control selector valve installed in an auxiliary hydraulic circuit in parallel with a manual main selector valve installed in each hydraulic cylinder hydraulic circuit for fork operation, and making it selectable. CONSTITUTION:When a remore-manual control selector valve 19 is selected to the manual side and a lever of a lift cylinder operating manual selector valve 23 is operated, pressure oil out of a hydraulic pump 16 is fed to a lift cylinder 6 from a main hydraulic circuit 20, and it is operated in an optional direction. In addition, when the selector valve 19 is selected to the remote control side, the pressure oil enters the lift cylinder 6 by way of a throttle valve 25 of an auxiliary hydraulic circuit 21 as one side of throttle valve of a meter- out circuit consisting of throttle valves 26, 26 with a check valve each is opened by a changeover of a lift cylinder operating solenoid selector valve 27. Therefore a flow rate of the hydraulic circuit 21 is reduced so that the lift cylinder 6 is operated at slow speed. Accordingly, a load is carried up to an approximate position manually by one operator and then he goes to the side, thus unloading can be done accurately.

Abstract: PURPOSE:To simplify the measurement of wire height and reduce the test time by measuring the peak height of wire and the height of wire at an edge of a chip where the wire should be out of touch to obtain the shape of bond wire. CONSTITUTION:A hybrid IC substrate 1 having a chip 2 and wiring pattern 6 is checked for the shape of a bond wire 5 on it.

Next, the peak of wire is focused to determine the peak height h1 and the XY coordinates of the peak. Then, the camera is moved vertically, and the wire height h2 at the edge 21 of the chip is determined when the edge 21 is clearly focused.

Title: Oscillation circuit
Inventor: KOMATSU SHIRO
IPC: H03K3/023
Filed: 1989-03-20
Abstract: PURPOSE:To oscillate a square wave with a high frequency by varying a potential at an input terminal of a comparator for a delay time in the output inverting operation of the comparator. CONSTITUTION:The potential of a noninverting input terminal of a comparator 10 is fixed to a reference voltage of 1/2V and a power supply voltage V is applied to an output terminal via a resistor R2. The potential of an inverting input terminal of the comparator 10 increases or decreases due to charge/ discharge by a resistor R1 and a capacitor C1 and the output inverting operation of the comparator when the potential is changed with respect to the reference voltage of the noninverting input terminal has a delay. Then the output potential of the comparator 10 is alternately inverted depending whether the potential at the input terminal is higher or lower than the reference voltage of the noninverting input terminal for the output inversion delay time and a square wave is obtained. Thus, the circuit constitution is simplified and a high frequency is able to be oscillated.
