Title: Gas compressor
Inventor: YAMAGUCHI MASARU
IPC: F04B39/16
Filed: 1995-10-20
Abstract: PROBLEM TO BE SOLVED: To enhance reliability by preventing any control failure in capacity due to the mixing of foreign substances. SOLUTION: A cylindrical solid filter 30 is installed in a borderline between an oil passage 21 and a dividing passage 22. This filter 30 extends into the oil passage 21 from an inflow port 22a of the diving passage 22, forming two clearance passages 31 and 31 in space between the surface side and an inner wall 21c of the oil passage 21. Any possible inflow of foreign substances into the dividing passage 22 and the side of a capacity control means 17 is prevented by the filter 30.  The foresin substances stuck to the filter 30 are eliminated by a flow of lubricating oil passing through the filter as it is, another flow of lubricating oil by way of the clearance passages 31 and 31, and a turbulent flow (vortex) to be produced at the downstream side of the filter 30 in combination, through which the flow of the lubricating oil ranging from the dividing passage 22 to the side of the capacity control means is always smoothened with being interrupted.

Abstract: PURPOSE:To attain to enhance clock accuracy to a large extent, by providing a power source circuit outputting voltage near to a battery voltage even when an apparatus power source is turned ON and changing over said voltage to system rated voltage only when a calender clock circuit part is accessed. CONSTITUTION:When an apparatus power source is turned ON and a calender clock circuit 5 is not accessed, level voltage turning a transistor 34 ON by programs control is applied to a signal line 10 and the transistor 34 is turned ON while transistors 31, 30 are turned OFF and the output of a change-over circuit 4 becomes ineffective. When the apparatus power source is turned ON and the calender clock circuit part 5 is accessed, the signal line 10 is earthed and the transistor 34 is turned OFF while the transistors 31, 30 are turned ON. At this time, because the emitter and collector voltages of the transistor 30 are low, a value almost near to prescribed voltage of 5V is supplied to the calender clock circuit part 5. When the apparatus power source was turned OFF, voltage of +3.0V is supplied to the calender clock circuit part 5 from battery 27 through a resistor 26.

Title: Gain adjusting circuit for video signal
Inventor: KAMINAGA KOZO
IPC: H03G3/20
Filed: 1985-12-06
Abstract: PURPOSE:To easily fix a preset state of a gain adjusting circuit whose gain is kept constant by adding an output from a fixed gain circuit with a control input for gain adjusting, comparing the output of the said addition with a feedback signal, and controlling the gain of a variable gain circuit by means of the output of the said comparison. CONSTITUTION:The synchronization level L of an input video signal from an input terminal 1 is detected by a synchronization-level detector 15, and multiplied G0 by the fixed gain circuit 16, and goes to be G0.L. Since the input video signal is multiplied by G by the variable gain circuit 3, an output of G.L is obtained from a synchronization-level detector 11. Assuming a gain-control input from an input terminal 5 to be (x), the output of an adder 17 will be G0.L+(x), which is transferred to a comparator circuit 12 to be compared with the output of G.L. The gain G of the circuit 3 is controlled so as to make the difference of the said comparison zero. When the preset state is desired, the gain control input (x) is made zero so that the gain G of the circuit 3 comes to be G0, and the level is fixed at the constant preset gain G0 regardless of the synchronization level L.
