Title: Variable venturi carburetor
Inventor: ARAI HISAHARU
IPC: F02M7/16
Filed: 1979-10-02
Abstract: PURPOSE: To atomize the fuel in a variable venturi carburetor by introducing vacuum into an atmosphere chamber defined by a suction piston when the opening degree of a throttle valve is small, so that the piston is moved to a more closed pisition thereby increasing the velocity of the air-fuel mixture.  
     CONSTITUTION: A suction piston 7 movable in the upward and downward direction corresponding to the venturi vacuum which acts on a vacuum chamber 13 defines an atmosphere chamber 12 into which an atmosphere is introduced through a vent port not shown. This atmosphere chamber 12 is also introduced with a vacuum generated between the piston 7 and a throttle valve 2 through a vacuum passage 17 including a valve 15. The valve 15 cooperates with the throttle valve 2 through a linkage 24 and a cam 19 in such a manner that when the opening degree of the throttle valve 2 is small, the valve 15 is opened so as to introduce a vacuum into the atmosphere chamber 12, which vacuum closes the piston 7.

Title: Method for providing liquid drip on material surface
Inventor: ARIGA TAMOTSU
IPC: B41J2/01
Filed: 1987-05-27
Abstract: PURPOSE:To enable the state of the physical quantity of the surface or the inside of a material to be made visible on the surface of the material, by a method wherein a signal input part of a sensor detecting the physical quantity of the surface or the inside of the material is provided, and a liquid drip is applied to the signal generating part of the material surface when a predetermined physical quantity of the material is detected. CONSTITUTION:An optical sensor 1 detecting the physical quantity of a material M irradiates the surface of the material M with light from a light source 6 through a light-projecting fiber 5 out of the tip end of a detecting probe 3 and transmits the reflected light to a spectral detector 8 through a light-receiving fiber 7. When irradiating normal reflectance part B of the material M, the optical sensor sends only an OFF signal to a piezo element 10. On the other hand, the light-irradiation of a part A causes the change in reflectance. If the part A is recognized to be an object part by the spectral detector 8, a signal is transmitted to an oscillator 13 through a signal cable 16; thus, an ON signal is sent to the piezo element 10 through a piezo applying signal tube 12 so that a predetermined amount of a liquid is jetted out of a nozzle 9 to be applied to the part A. Furthermore, the liquid is supplied from a liquid tank 15 to the nozzle part through a liquid transfer tube 14.

The filling material is deposited at such a relatively large power and deposition rate as to close the mouth of the cavity, and thereafter the filling material is pushed into the cavity at a high pressure to substantially fill the cavity therewith. Such conventional material as to have a low dielectric factor and as thermally unstable at a conventional processing temperature can be used. To this end, a relatively low processing temperature and high voltage are employed.

Filed: 1983-07-15
Abstract: PURPOSE:To shorten connection time with a channel device by executing dynamic address conversion processing when a dynamic address conversion request is sent from the channel device, and returning a response for dynamic address conversion request before termination. CONSTITUTION:When the channel device 3 requires prefetch DAT (dynamic address conversion), the channel controller 2 receives the requirement, immediately returns the response signal for the prefetch DAT requirement to the channel unit 3, and opens the channel device 3. Thereafter, when the channel controller 2 requires DAT processing for the CPU1, the CPU1 returns the actual address to the channel controller 2 after fixed time, and therefore, stores the actual address in the actual address register 21. When the channel device 3 reguires actual address read for prefetch DAT requirement, contents of the actual address register 21 are transferred to the channel unit 3. Afterwards, the channel device 3 executes memory access by using the actual address.
