Title: Air fuel ratio detector
Inventor: MIYATA SHIGERU
IPC: G01N27/419
Filed: 1985-04-30
Abstract: PURPOSE:To detect an air fuel ratio accurately by acceleration the gas exchange in a diffusion chamber through the operation of a pump current control means and a current supply means when the air fuel ratio varies from a leak area to a rich area or vice versa. CONSTITUTION:When the air fuel ratio varies from the rich area to the leak area and an oxygen concentration electron element M2 generates electromotive force exceeding a set value, a reverse pump current flows to an oxygen pump element M3 and oxygen in exhaust gas is sucked in the diffusion chamber. At this time, the element M2 is operated as a pump element temporarily through the operation of a current supply means M7 to suck the oxygen in the exhaust gas in the chamber M1, thereby accelerating the gas exchange nearby the electrode of the element M2 facing the chamber M1. When the air fuel ratio varies from the leak area to the rich area, on the other hand, the element M2 is operated as a pump element temporarily through the operation of the means M7 and oxygen in the chamber M1 is discharged to the exhaust gas, thereby accelerating the gas exchange nearby the electrode of the element 2 facing the chamber M11. Thus, the gas exchange in the chamber M1 is performed smoothly.

Title: Video information processing device
Inventor: TOMARINO KAZUHIRO
IPC: H04N7/087
Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To rewrite rewrite-information such as a control program automatically without giving effect on video information and imposing trouble on the user. SOLUTION: Rewrite data such as a new control program are multiplexed on information part of video information such as a vertical blanking period and a horizontal blanking period applied to the processing unit without giving effect of the video image. A rewrite data presence/absence decision section 1 gives a discrimination output to a data rewrite section 3 when rewrite data are in existence for the vertical blanking period of the video information. Furthermore, a rewrite data demultiplex section 2 extracts the rewrite data multiplexed on the video information and gives the rewrite data to a rewrite memory 4. A data rewrite section 3 writes the rewrite data extracted by the demultiplex section 2 to the rewrite memory 4 only when the section 3 receives the discrimination output denoting the presence of the rewrite data from the decision section 1.

Title: Fluid atomsphere convertion control
Inventor: KIMURA SADAHIRO
IPC: F02M33/00
Filed: 1978-08-03
Abstract: PURPOSE: To control fluid to a desired condition, a fluid route is provided with a control material capable of repeating occulsion and discharge of one or more of material contained in a liquid.  
     CONSTITUTION: This method of control is used to control a composition comprising fluid, among many properties of fluid. The method is carried out by placing a control material capable of repeating occulusion and discharge of one or more of material contained in a liquid. In internal combustion engine, for example, concentration of a mixed gas of air and gasoline is controlled by active carbon 12, a control material. In this case, when an electromagnetic switch 11 is closed to heat a heater 13, the temperature of the active carbon 12 rises up. When the switch is turned off, the temperature falls. As such, the controllable active carbon 12 is passed through mixed gas, changing the gas concentration as shown in the figure.

IPC: B23K9/12
Filed: 1979-07-26
Abstract: PURPOSE: To reduce the number of parts, eliminate malfunction and obtain stable sequence controlling by changing conventional semiconductor switching elements to trigger switches, relays and solenoid valves.  
     CONSTITUTION: With a trigger switch 16 off prior to welding, the electric current of an electric power source 18 flows in a relay 12 and is charged to a capacitor 60. Next, when the switch 16 is turned on at the time t 1 , the contacts 62a, 62b of an electric current detector invert and at the time t 2  exciting current is supplied to a solenoid valve 14, by which ordinary arc welding is started. Thence, when the switch 16 is turned off at the time t 3 , the capacitor 60 is discharged and the welding is continued. When the switch 16 is next turned on at the time t 4  for the purpose of crater welding, the contacts 12a of the relay 12 are driven by the capacitor 60, by which the welding is changed over to crater welding. If the switch 16 is turned off at the time t 5 , the contacts 62a and the solenoid valve 14 are opened and the contacts 12b close, thus resetting to the state prior to welding.

IPC: G02B6/42
Filed: 1979-07-27
Abstract: PURPOSE:To easily and surely suppress the reflection of light on the incident side by inclining the incident face of a light isolator with respect to optical axis. CONSTITUTION:For example, in the case in which a parallel beam converting lens 16 is on the front face of a light isolator 10, the light isolator 10 is constituted by a Faraday rotor 11, a polarizer 11 and an analyzer 13. The laser light 15 from a semiconductor laser 14 is paralleled by a lens 16 and these parallel beams pass through a polarizer 12 and an analyzer 13 and are coupled to an optical fiber 18 by a circular cylindrical lens 17. Here, the incident face 12' of the polarizer 12 is inclined with respect to the optical axis; therefore the parallel laser beams are prevented from being reflected thereby and returning to the semiconductor laser 14. Even in the case in which the converged laser light enters the circular cylindrical lens 21 provided to the front face of the polarizer 20, if the beam west is positioned on the inclined incident face 21', the reflected light may be suppressed. Thereby, the reflected light may be suppressed easily and surely.

Title: Highly thin grinding stone
Inventor: ABE TAKAKO
IPC: B24D5/12
Filed: 1988-04-19
Abstract: PURPOSE:To obtain a grinding stone with high stiffness capable of deep cutting by arranging high strength ceramic whiskers other than super abrasives to the direction normal to the axial line of the grinding while being dispersed into metallic plating phases. CONSTITUTION:Numbers of ceramic whiskers 11, 11,... are dispersed into metallic plating phases 10 in such a way that these whiskers 11, 11,... are arranged to the direction normal to the axial line of these whiskers. The deformation of metallic plating phases to the aforesaid direction is accordingly restrained so as to improve the stiffness of a grinding stone for reducing the deflection thereof. Resultantly, even when the aforesaid stone is used for full cutting by which a wafer is deeply cut, it may withstand great grinding resistance sufficiently. Even if taping materials are adhered onto the edge so as to make it dull, there is little risk of failures. In grinding operations, whiskers 11, 11,... come suitably out of the grinding stone so as to form chip pockets at traces left over therein, these chip pockets thereby allow chips to be effectively taken out so as to accelerate the self edge forming action of super abrasives for improving the sharp cutting of the grinding stone.
