Title: Lubricating device for rotary piston engine with supercharger
Inventor: KODAMA HIROSHI
IPC: F01C21/04
Filed: 1980-04-11
Abstract: PURPOSE: To prevent blow off back of oil by controlling the pressure at the suction port of a pump to be nearly equal to the pressure at an intake pipe located at the downstream of the supercharger in the case when the inner-peripheral surface of the actuating chamber of the rotary piston engine is lubricated with oil supplied from a metering pump.  
     CONSTITUTION: When the opening degree of a throttle valve is increased and the supercharger 7 starts therewith to work fully, the pressure of the intake pipe at the downstream of a blower 7b becomes positive. This positive pressure is introduced into the pressure chamber 23 of a pressure controlling valve 21 in a control device 15 through the intermediary of a pressure passage 25 and presses downward a plunger 26 through the intermediary of a diaphragm 22. Therefore, the springing force of a spring 27 is increased and thereby the pressure-regulation characteristic of an oil chamber 16 is enlarged. Accordingly, the pressure at the suction port 13a of the metering pump 13 is controlled to be nearly the same with the aforesaid positive pressure of the intake pipe and thereby the oil from the pump 13 is supplied smoothly to the actuating chamber 3 placed under nearly equal pressure through the intermediary of an oil passage 14 without causing the blow back thereof.

Title: Improving apparatus for quality of water
Inventor: MIO KESATO
IPC: E02B3/02
Filed: 1995-03-08
Abstract: PURPOSE: To increase the oxygen content of ooze, and to improve the quality of water, by providing a function of generating rising vortex flow by a swivel type rotary body, by providing a function of digging up ooze like a shovel, and by causing the subdivision of bubbles together with the agitation of the ooze. CONSTITUTION: An air-taking in part 12 is provided at the bottom part of a sleeve-shaped diaphragm. A swivel type rotary part 22 having radially placed hollow arm parts 22a which communicate with the air-taking in part 12 and which are rotatably connected therewith is provided, and air-blowing parts each are provided at the top ends of the hollow arm parts 22a. Furthermore, air-blowing parts for digging up ooze each are formed at the top ends of the hollow arm parts in opposite direction to the rotary direction of the rotary part 22 and pointing obliquely downward. The swivel type rotary body 2 rotates by reaction force of air-splaying pressure, produces voltex flow energy, and subdivides bubbles, and thus oxygen is allowed to dissolve into the ooze.  Agitating energy digging up the ooze is applied by air blowing from the air-blowing parts and the oxygen is efficiently mixed into the ooze. In this way, the quality of water is improved and the ooze is made efficiently inorganic.

Title: Picture-quality improving circuit of color television receiver
Inventor: OOTA MASUTOMI
IPC: H04N9/77
Filed: 1978-04-24
Abstract: PURPOSE: To make it possible to reproduce a picture whose contour is clear even at the boundary where the picture changes in color.  
     CONSTITUTION: By passing through high-pass filter 1, luminance signal Y has the only high-band component left and is slightly delayed. Color-difference signal C, on the other hand, is separated into two signals; one signal is supplied to switch alternation circuit 4 via delay circuit 3, and the other is directly to circuit 4. As for the output color difference signal, switch alternation circuit 4 is so switched that signal (d) delayed by circuit 4 will be outputted before a switching signal is supplied from trigger generating circuit 2 to switch alternating circuit 4 by the high component of the luminance signal, namely, a signal indicating the contour position of the picture so as to output the undelayed color difference signal. Then, signals C and (d) are compared by comparator circuit 5 and when the both agree each other, switching signal (f) is supplied in order to output signal (d) by switching. Further, the high-band component of the luminance signal energizes circuit 4, whose output is changed from signal (d) to C.

Abstract: PURPOSE:To inexpensively enhance the grade of a pixel and a printing speed in an ink jet head forming a unit pixel by a plurality of dots. CONSTITUTION:Two nozzles arranged so as to cross the advance direction of a nozzle at a right angle receive the supply of the first pulse voltage to emit ink droplets at the same time to form two dots DI.
