Title: Intake device for internal-combustion engine
Inventor: KATO MANABU
IPC: F01L3/22
Filed: 1985-04-04
Abstract: PURPOSE:To prevent thermal radiation of intake valve and to heat and vaporize the intake mixture gas through the intake valve by securing the valve seat through a low thermal transmission member to the cylinder head in the port at the intake valve side of double intake valve engine to be supplied with fuel. CONSTITUTION:In an engine having two intake valves in single cylinder, an intake port having an intake valve is arranged independently while a fuel injection valve is arranged at the normally communicatable intake port and a valve openable under high speed is arranged at another intake port. The intake valve 1A at the port 2A arranged with a fuel injection valve and to take in the air normally will seat in the valve seat 12 thus to radiate the heat from the valve 1A to the cylinder head 11. But since the valve seat 12 is made of such material as having considerably lower thermal transmission factor than the cylinder head 11, the heat is hard to be radiated from the valve 1A to the cylinder head 11 thus to never cool easily. Consequently, the mixture gas contacting against the valve 1A is vaporized sufficiently, resulting in improvement of combustibility.

Abstract: PURPOSE:To enable to effectively decrease noise level by providing a device for changing the frequency of supplied power to a stepping motor to alter the diffusing direction of air by rotating a deflecting blade of diffusion direction. CONSTITUTION:A deflecting blade 5 which alters the diffusing direction, a stepping motor 8 which rotates the blade 5, and a frequency changing device 10 which raises the frequency of supplied power to the motor 8 when the load torque of the motor 8 is large, are provided, and a signal from a position detector 9 which detects the positions where the load torques of the motor 8 are large and small is fed to the device 10. When the detector 9 detects the position where the load torque is large, the device 10 receives a signal from the detector 9, raises the frequency of the supplied power to the motor 8, while when the detector 9 detects the position where the torque is small, the device 10 lowers the frequency. In this manner, the period of the blade 5 is maintained at the desired swing, thereby decreasing the noise.

Title: Color video amplifier circuit
Inventor: SEKO KAZUYUKI
IPC: H04N5/14
Filed: 1986-03-27
Abstract: PURPOSE:To dislay two kinds of blue colors different in chromaticity by outputting a weak red and green video signal in addition to a blue video signal when the blue video signal is inputted based on a control signal. CONSTITUTION:When a switch S1 is connected to the position of +5V, the signals inputted to red/green/blue circuits are amplified independently. When the switch S1 is connected to the position of the ground and only the blue signal is inputted, components, D2R, Z2R, R2R pass the signal, amplified by a Q1R and oututted from a r4, the sugnals pass through components D2G, Z2G, R2G, amplified by a Q1G and a signal is outputted from a g4. Thus, red/blue colors are displayed slightly in addition to the blue signal on a cathode-ray tube and the color reaches a blue color close to a white color, that is, a light blue color as a whole.

Title: Welding method of pipe to flat plate or to drum plate
Inventor: MATSUI SHIGETOMO
IPC: B23K15/00
Filed: 1978-06-13
Abstract: PURPOSE: To make conventional complex welding set useless and to reduce the cost of welding, by welding a pipe to a flange made by cutting a suitable portion of a flat plate or drum plate by means of an electron beam welding unit, then by welding the flange to the cut off part.  
     CONSTITUTION: A comparatively large flange 4 is cut off from a drum plate 1 around an hole 3 to which a pipe 2 is to be fitted. The flange 4 is welded to the pipe 2 in a vacuum chamber by electron beams securely and easily. Thereafter, the pipe 2 welded to the flange 4 is fitted to the cut off part 5 of the drum plate 1 and welded to the drum plate 1 by conventional welding method. Hereby, coupling is effected by welding plate to plate, facilitating the field work considerably. This method makes it possible to weld the pipe 2 to the flange 4 easily even when the drum plate is thick or when the bevel shape for fitting a pipe to a drum plate is complex. Consequently the cost of welding is remarkably reduced because the weldig is conducted efficiently by conventional method without use of long time.
