Title: Steering checking device for tractor
Inventor: FUKUOKA YASUTAKA
IPC: B60G9/02
Filed: 1988-10-11
Abstract: PURPOSE:To reduce the maximum steering angle for preventing a steering wheel to abut to a vehicle body so as to improve turning performance by allowing a pitman arm to abut to a restriction stopper only when an axle housing oscillates over a fixed range. CONSTITUTION:When a steering handle is operated, right and left steering wheels 4 are steered via a pitman arm 2, while an axle housing 5 oscillates upward and downward on account of the grounding of the steering wheels 4 following the tilt on the running road surface. In this case, when oscillation of the axle housing 5 remains within a fixed range, the pitman arm 2 is rotated to abut on a pair of right and left stoppers 3, therewith the maximum steering angle takes place. On the other hand, when the oscillation of the axle housing 5 is beyond the fixed range, the maximum steering angle is reduced due to restriction in turning movement of the pitman arm 2 on account of abutment of the pitman arm 2 on a pair of right and left restriction stoppers 6.

Abstract: PURPOSE:To permit the detection of the generating amount of vapor automati cally and continuously by a method wherein a refrigerant liquid level detector, detecting the liquid level of refrigerant in a refrigerant tank, and a device, indicating or recording the detected liquid level of the refrigerant, are provided. CONSTITUTION:When the liquid level of refrigerant is changed from H1 to H2 when time is elapsed from (t1) to (t2), the change DELTA WR of the level of refrigerant per unit time is operated by formula; DELTAWR=(H2-H1)/(t2-t1). Now, when the area of bottom of a refrigerant tank 1 is indicated by AT, the change WR of the amount of refrigerant per unit time is operated by a formula WR =DELTAWRXAT. Accordingly, the generating amount of vapor can be operated. The liquid levels H1, H2 of the refrigerant are detected by an electronic type refrigerant liquid level detector 15 and are indicated or recorded by a refrigerant liquid level indicating and recording meter 17. According to this method, the generating amount of vapor can be known immediately.

IPC: C12G3/02
Filed: 1988-10-12
Abstract: PURPOSE:To prepare a melon liquor having high quality in high operation efficiency at a low cost by adding a specific amount of ethyl alcohol containing a specific amount of lactic acid to a ripe melon, aging and squeezing the melon, adding water and optionally sugars, organic acids, etc., to the juice and fermenting the juice with yeast. CONSTITUTION:Ethyl alcohol added with about 0.5% of lactic acid is added to a ripe melon and the melon is aged for >=6 mouths while keeping the alcohol content of the fruit juice to about 20%. After aging, the melon is squeezed and the juice is added with water and optionally sugars, organic acids, etc., and fermented with yeast to obtain the objective melon liquor. The sterilization effect can be improved by the synergistic effect of ethyl alcohol and the small amount of lactic acid added to the ethyl alcohol to be added to the ripe melon. Accordingly, the amount of alcohol can be decreased to prevent the deterioration of the characteristic properties of the melon.
