Title: Refrigerating apparatus
Inventor: KAWASHIMA KENJI
IPC: F25B1/10
Filed: 1994-11-29
Abstract: PURPOSE: To prevent a misty refrigerant from flowing into a suction pipe line in the state that a damper is throttled at the time of starting-up and of low-loaded operation, by a method wherein a valve opening or closing corresponding to the state that the misty refrigerant in an economizer flows into the suction pipe line between the economizer and a suction chamber for the second stage is provided between them, and the flow rate of the misty refrigerant is controlled. CONSTITUTION: A gaseous refrigerant evaporated in an evaporator 11 is compressed by a first stage impeller 2 through a vane type damper 12 and is again compressed together with the gaseous refrigerant from an economizer 8 by a second stage impeller 3, following which the gaseous refrigerant compressed at a high pressure is led into a condenser 6. In the condenser 6, the gaseous refrigerant is condensed with cooling water and is turned into a liquid refrigerant, and the liquid refrigerant is sprayed into the economizer 8. Part of the liquid refrigerant is led to the second stage impeller 3 through a valve 17 as the gaseous refrigerant, and the rest thereof is returned into the evaporator 11 as the liquid refrigerant.  At this time, when the vane type damper 12 is throttled, the flow rate of the gaseous refrigerant discharged from the first stage impeller 2 is decreased, and hence the second stage impeller 3 without the vane type damper increases a flow rate from the economizer 8, and its increase may cause the inflow of a misty refrigerant. However, the inflow of the misty refrigerant can be prevented by throttling the valve 17.

Title: Semiconductor laser driving circuit
Inventor: SANADA TAKESHI
IPC: H04B10/07
Filed: 1987-11-20
Abstract: PURPOSE:To prevent an excess light from irradiating at the time of coming data and to increase the life of a semiconductor laser by comparing by a comparator the output of a mark ratio detector, the output of a photoelectric converter with a reference voltage, outputting a control voltage, and setting a bias current to a predetermined bias current value by these outputs. CONSTITUTION:When continuous data are transmitted, a transmission data request signal (a) is fixed to 'High', and the bias current of a semiconductor laser 11 is so controlled similarly at the time of transmitting burst data by a mark ratio detector 16, a photoelectric converter 18, a comparator 19 and a bias current controller 20 that an optical output peak power P0 becomes constant. Accordingly, the laser 11 does not excessively radiate a light even if the data are abruptly input so as to set the bias current of the laser 11 substantially to a predetermined current value of a threshold current value before the data is input with the signal (a), and further since the bias current fed to the laser 11 is turned OFF at the time of inputting no data, wasteful power is not consumed, but the life of the laser 11 can be extended.
