Title: Self-switching noise suppression type receiver
Inventor: MATSUSHITA HIROSHI
IPC: H04N5/213
Filed: 1990-07-17
Abstract: PURPOSE:To prevent production of interference fringe on a screen of a receiver by introducing a capacitor absorbing suppressing a switching noise from a rectifier circuit to the receiver. CONSTITUTION:A color control pulse outputted from a microcomputer 1 to a color control pulse signal line 2 is a signal repeating a low level and a high level. A diode 3 repeats the switching operation by the signal. A ringing component generated in the switching operation is eliminated by connecting a smoothing capacitor C2 across the diode so as to unsharpen the switching voltage waveform. Thus, the capacitor absorbing suppressing a switching noise from a rectifier circuit is introduced to the circuit to eliminate production of interference fringe on the screen of the receiver.

IPC: F02K9/46
Filed: 1985-08-28
Abstract: PURPOSE:To simplify an engine in structure as well as to reduce an energy loss, by setting up a jet pump, formed in branching off a driving fluid generating pipe line from a fuel feed pipe line, in this fuel feed pipe line which feeds a combustor with liquid hydrogen. CONSTITUTION:A low pressure fuel feed pipe 11 is connected to a fuel tank where liquid hydrogen is filled up. High pressure oxygen gas spouted out of a driving gas spouting nozzle 12 is mixed with low pressure liquid hydrogen to be sucked up from the low pressure fuel feed pipe 11 at a mixing part 13. After engine starting, heat out of an engine combustor is impressed on a branch pipe 16, whereby the high pressure hydrogen gas is heated up and gasified, so that it is spouted out of the nozzle 12. Thus, such a cryo-propellant rocket engine as being less in an energy loss is securable with a very simple structure.

IPC: G03B42/02
Filed: 1983-10-05
Abstract: PURPOSE:To improve the power of separation between accelerated exciting light and accelerated fluorescence by using laser light as the accelerated exciting light and using the combination of two or more kinds of filter different in half- value width for the purpose of separating the accelerated exciting light and the accelerated fluorescence. CONSTITUTION:An object 12 is arranged between a radiation generator 11 and a radiographic image conversion panel 13, and radiation is irradiated to the object 12. Electrons and/or positive holes stored in the trap level of an accelerated fluorescence layer of the radiographic image conversion panel 13 are excited by a laser light source 14 to radiate a stored image as the accelerated fluorescence. This accelerated fluorescence is separated from the laser light by two or more kinds of filter 18 different in half-value width and is converted to an electric signal by a photodetector 15. The electric signal of the photodetector 15 is sent to an image reproducing device 16 and is displayed as a radiographic image on an image display device 17. Thus, the power of separation between the accelerated exciting light and the accelerated fluorescence is high sufficiently to obtain the practical radiographic image of less noise.
