Title: Egr valve
Inventor: SASAKI NORIO
IPC: F02M25/07
Filed: 1994-08-26
Abstract: PURPOSE: To prevent entrance of a foreign matter, impeding movement of a valve stem, between the valve stem and a bush. CONSTITUTION: An EGR valve 5 constituting the exhaust gas recirculation(EGR) of an engine is provided with casings 6 and 11 and a valve steam 18 supported by a bush 22 and a baffle 23 is provided therein. A valve body 20 arranged at the lower end of the valve stem 18 is seated on a valve seat 21 arranged in a casing 6. A diaphragm 10 located in the casing 11 vertically moves the valve stem 18 occasioned by displacement of itself. Based on movement of the valve stem 18, an opening between the valve body 20 and the valve seat 21 is regulated. The upper part of the bush 22 is formed in the shape of a truncated cone and has an upper surface spreading outward centering around the valve stem 18 and the upper surface forms a slope 22c inclined downward with the valve stem 18 serving as a center.  Thus, water and mud with which the upper surface of the bush 22 is splashed flows down along a slope 22c in a direction in which the water and the mud are spaced away from the valve stem 18.

Title: Apparatus for washing exhaust gas
Inventor: KOUFUKU HIDEO
IPC: B01D53/50
Filed: 1985-09-13
Abstract: PURPOSE:To attain the enhancement of adsorbing efficiency and the simplification of the inner structure of a tower, by a method wherein the main body of either one of washing solution supply piping and a piping support is integrally provided with the other main body. CONSTITUTION:A washing solution flowing through the liquid flow passage 4 of main piping passes through a branched pipe 2 to be sprayed from the spray nozzle 9 provided to the leading end of said branched pipe 2. At this time, because the main piping 1 is formed by the main body of a piping support 8, said main piping 1 has sufficient strength only by this structure and generates no bending. Because there is no separate piping support, the reduction in the opening area of a gas-liquid contact tower and the jetting direction of the sprayed solution is not obstructed and adsorbing efficiency is enhanced. The inner structure of the tower is also simplified and the economical tower is constituted.

On the other hand, a printer is equipped with a plurality of data expanding means for expanding a plurality of sets of compressed data at a variable data compression ratio and a means to send an image for measuring an image drawing rate. The terminals 100 of the host computer compress image data using a stored data compression method and the stored data compression ratio. Further, the terminals 100 create a command for image creation to the printer. The printer expands the image data at the command for image creation received from the terminals 100 of the host computer using the stored data compression method and data compression ratio.  Thus, it is possible to eliminate the unnecessary compression/expansion of the image data.

IPC: G02B7/32
Filed: 1985-09-13
Abstract: PURPOSE:To remove the unstable action due to the noise by controlling the gain of the gain control amplifier with the smaller signal out of two photodetecting elements. CONSTITUTION:The output of Si photo diodes 6A and 6B to receive the reflecting light from an object is converted to the voltage signal by electric current-voltage converting circuits 35A and 35B, and inputted respectively through BPF36A and 36B and synchronizing detecting circuits 37A and 37B to a difference signal circuit 38 and a signal selecting circuit 39. At the circuit 38, the difference of both channels is operated, and the difference signal is outputted to a gain control amplifier 40. On the other hand, at the circuit 39, the smaller signal out of both channel signals is selected, and this is inputted to the amplifier 40 as the control signal. When the gain is controlled by the control signal, the difference signal outputted from the amplifier 40 comes to be the signal which is changed in the curve shape. Such a difference signal output is inputted to a deciding circuit 41, the focus deciding action is executed and the focus action is executed by the output. Since the deviation is enlarged by the device, the normal action is executed even when the noise is applied.

Title: Preload type electric contact terminal
Inventor: DEIMITORII JII GU RAABU
IPC: H01R12/57
Filed: 1981-12-16
Abstract: Electrical contact terminal of the flat coplanar type which is manufactured by stamping sheet metal, has a yoke portion having a latch arm and a spring arm extending therefrom. The latch arm is relatively short while the spring arm is of sufficient length to permit deflection thereof when the terminal is placed in service. The two arms have free ends which are adjacent to and resiliently biased against each other. The free ends are latched to each other by latching means which permits movement of the free end of the spring arm along a side edge of the latch arm. An edge portion of the spring arm serves as a contact portion and current flows from this contact portion to the end of the spring arm then to the latch arm and to the yoke portion of the terminal to provide a short low inductance current path for the current. The spring arm is in a preloaded and flexed condition so that an elevated contact pressure is achieved.

Title: Method and device for detecting welding arc
Inventor: MIYATA SOUZABUROU
IPC: B23K9/095
Filed: 1981-12-18
Abstract: PURPOSE:To measure welding speed automatically and accurately by giving command to starting and finishing of work later than the time of detection of  arc light detector installed in the welding start and welding finishing sections. CONSTITUTION:When a welding arc arrives at a distance l1 from the installed position of arc light detectors 5a, 5b, if voltage is raised to power source voltage, the start and terminal of the distance L1 is detected by detectors 5a, 5b.  This differs from detection of start and terminal of distance L0 between the  positions of the detectors 5a, 5b. The first delay relay or second delay relay is  operated according to output voltage of the detectors 5a, 5b. In this case, delay time of the delay relay corresponds to, for instance, the time in which the arc 4 moves the distance la. Accordingly, it can be brought sufficiently close to the time in which the arc moves the distance L0, and detection error due to raidal spreading of arc light can be compensated substantially.

Abstract: PROBLEM TO BE SOLVED: To provide a plastic diffraction molded lens hardly causing a transcription failure of a diffraction groove shape even if applying injection molding, and to provide an optical system using the lens. SOLUTION: Grooves 31-33 for discharging gas are formed in a diffraction groove transcription part 21 of a mold member 20 for this lens. The grooves 31, 32, 33 are formed such that the grooves 31, 32, 33 cut respective grooves of the diffraction groove transcription part 21 into pieces 22a, 22b.
