Title: Lubricating device of compressor
Inventor: FUJIO KATSUHARU
IPC: F04B39/02
Filed: 1982-09-17
Abstract: PURPOSE:To enable feed of lubricating oil to be stabilized in response to the operation state of a compressor by adjusting an oil passage opening while changing a spring constant based on lubricating ol temperature. CONSTITUTION:Lubricating oil in an oil reservoir 1 flows due to the operation of a pump device or the differential pressure through an oil passage 8, a cylinder 3, an oil passage 4, and a notched groove 10 into an oil passage 11. When the temperature of the lubricating oil exceeds the specific temperature, the coefficient of linear expansion of a coil spring 7 rapidly increases to cause a larger spring constant, and a rubber-made valve body 6 is pushed up and the height of the notched groove 10 is decreased, allowing the opening of the notched groove 10 to be reduced. When the temperature of the lubricating oil drops below the specific temperature, the spring constant is reduced and the height of notched groove 10 of the valve body 6 returns to the original shape due to the elastic force of rubber, so that it is possible to stably supply lubricating oil.

Abstract: PURPOSE:To quicken turning-on, by decreasing the number of windings flowing an on-gate current of a pulse transformer turning on/off a gate turn-off thyristor than that for an off-gate current. CONSTITUTION:A gate of gate turn-off thyristor GT01 is connected to a resistor 15 via a diode 14 flowing a turn-on current with a voltage from a secondary winding 132 of a pulse transformer 13. A transistor (TR)4 flowing an on-gate current is connected to the 1st primary winding 1311 of the transformer 13 and a TR5 flowing an off-gate current is connected to the 2nd primary winding 1312. If the winding ratio of the windings 1312, 132 is taken as 5:1 and that of the windings 1311, 1312 as 1:2, then the generation of avalanche current at turning-off of the GT01 can be prevented, an output voltage of the winding 1312 at turning- on is increased and the leading of the on-gate current is made steep. Thus, the turning-on of the GTO can be quickened and the minimum on-time of the GTO can be decreased.

Abstract: PURPOSE:To obtain a non-linear resistance element including a silicon nitride film having characteristics usable as an active element for a liquid crystal display by forming a non-linear resistance film of a nitrogen-added amorphous silicon hydride having an unpaired electrode density in a specific range. CONSTITUTION:In a non-linear resistance element having an insulating substrate 41 on which a first conducting film 42, a non-linear resistance film 44 and a second conducting film 45 are deposited one over another in that order, the non-linear resistance film 44 is formed of nitrogen-added amorphous silicon hydride having an unpaired electron density in a range from 1X10<17> to 5X10<18>cm<-3>. If the film is deposited by the plasma CVD process under a vacuum of 100 Pa with high frequency power of 200 W at a substrate temperature of 250 deg.C, for example, the non-linear coefficient alpha and the unpaired electron density are varied, as shown in the graph, as flow ratio between SiH4 gas and N2 gas is changed. Namely, as the flow ratio of SiH4/N2 increases, the non-linear coefficient alpha increases and then decreases while there is a region where the coefficient keeps a relatively large value around 10, and this region corresponds to the range suitable for the non-linear resistance element.
