Title: Installation method of work
Inventor: MIYAMURA KEIICHI
IPC: B23P19/02
Filed: 1986-12-05
Abstract: PURPOSE:To certainly carry out the press-fitting work for a work in a short time by carrying out the squeezing work for one slidable contact surface of a pair of works and press-fitting the slidable contact surface onto the slidable contact surface of another work and then welding the both slidable contact surfaces of the both works. CONSTITUTION:A coupling 11 is set onto a squeezing device 12, which squeezes the slidable contact surface 11a of the inside diameter. Then, the disturbance generated on the slidable contact surface 11a in the cutting finishing work is squeezed by the difference between the diameter of a punch 12b and the diameter of the slidable contact surface 11a, and the coupling is finished to a smooth surface as a whole. Then, the slidable contact surface 11a of the coupling 11 is position-adjusted to the slidable contact surface 14a of a driven gear 14 by a press-fitting device 13, and press-fitted by lowering a punch 13b. Since the slidable contact surface 11a is finished smooth at this time, press-fitting can be carried out without generating gnawing. Further, the need of pouring lubricating oil into between the both slidable contact surfaces 11a and 14a is avoided in the press-fitting process. Then, the both slidable contact surfaces 11a and 14a are welded by the means such as electron beam. Since lubricating oil does not present at this time, no welding trouble is generated.

Title: Controlling method for absorption refrigerator
Inventor: ISHIKAWA TAKEO
IPC: F25B15/00
Filed: 1988-11-18
Abstract: PURPOSE:To prevent an absorption liquid pump from starting and stopping and to stabilize the coolant outlet temperature of an evaporator by operating the pump at the time of start of an absorption refrigerator, and controlling the frequency of power supplied to the pump on the basis of a time during which the absorption liquid level of the regenerator is shifted from a low level to a high level. CONSTITUTION:Power having a predetermined frequency is supplied to an absorption liquid pump 15 at the time of start of an absorption refrigerator, and a time during which the absorption liquid level of a regenerator 1 is shifted from a low level to a high level is measured. If the time is long, i.e., the rising speed of the liquid level is slow, the frequency of the power fed to the pump after starting is increased. If the time is short, i.e., the rising speed of the liquid level is fast, the frequency of the power is reduced. Thus, dilute absorption liquid matched to the refrigerant evaporation amount in the generator 1 is fed to the regenerator 1, and variation in the liquid level in the generator 1 after starting is reduced. The start and stop of the pump 15 are suppressed, the thermal exchanges between the dilute liquid and the concentrated liquid, intermediate liquid in heat exchangers 6, 7 are continued to stabilize the coolant outlet temperature.
