Title: Manufacture of steel tube
Inventor: OOTA SHIYUUJI
IPC: B22F5/12
Filed: 1979-08-28
Abstract: PURPOSE: To prevent steel tubes from producing welding defects by forming a coating film through coating the surface of steel tubes with a liquid covering material which is mixed with a low melting point metal powder and a wetness aid agent and then heating at a high temperature.  
     CONSTITUTION: After a nonsurface-treated steel band is roll worked to form a tublar shape, tublar edges are bonded with each other by resistance welding etc. to form material tube. A liquid covering material is coated for which the powder of metal of relatively low melting temperature, such as copper or tin, is added with ethylcellulose etc. When the material tube is heated at a temperature higher than the melting point of the liquid covering material, a steel tube is obtained which has a coat of metal, such as copper or tin, on the surface. This enables to prevent welded tube edges from defective portions where welding is not performed due to absence of copper grains adhering.

Title: Weighing instrument preventing effect of air-flow
Inventor: KITAMOTO KIYOTERU
IPC: G01G21/28
Filed: 1986-05-15
Abstract: PURPOSE:To sharply increase the weighing accuracy of an instrument by arranging a load transmitting mechanism penetrating a side wall portion separating a weighing chamber and a mechanism chamber from each other. CONSTITUTION:The load of an object being weighed located on a weighing pan 3 is transmitted to a beam 12 via an arm 4 and a Roberval mechanism 16 and the displacement of the beam 12 is detected by a sensor. Displacement signals thus obtained are amplified by a servo mechanism and resulted output current is supplied to an electromagnetic unit 14 to balance the beam 12. Since a force generated by the electromagnetic unit 14 is proportional to an electric power supplied thereto, the electric power is outputted as a voltage and displayed (15) as the load of the object being weighed. In the operations described above, air in a mechanism chamber 17 tends to flow into a weighing chamber 2 at a lower temperature and passes an opening 18a to let the weighing chamber 2 and the mechanism chamber 17 communicate with each other. The air flowing out of the chamber 17 through the opening 18a rises substantially along a partition 18 and does not affect the weighing pan 3. Thus, a weighing can be conducted with an extremely high accuracy.

Abstract: PURPOSE:To make it possible to use a motor of a small output by transmitting the rotating force of a motor to a reciprocating rod only when a component of a force in a direction parallel to a shifting direction of the reciprocating rod, of the rotating torque of the motor reaches the vicinity of a maximum value. CONSTITUTION:A lip-shaped rotary member 6 starts a continuous constant-speed rotation in accordance with the rotation of a geared motor 4. Therefore, a pressing part 6a comes into contact with a portion 8 to be pressed of an upper reciprocating rod 7, and thereafter presses the part 8 to be pressed by a force corresponding to a component t1 of a force in the direction parallel to the reciprocating rod 7, is pressed in the right side direction.

Upon this occasion, a part 8' to be pressed of a lower reciprocating rod 7' placed in an interlocking relationship with an upper reciprocating rod 7 is preset so that it occupies a position (b). When the rotary member 6 continues further to rotate and the lower reciprocating rod 7' in turn is started to shift in the left hand direction, and the part 8' to be pressed reaches a position (b'), its movement is stopped.

Title: Intake pipe for spark ignition internal combustion engine
Inventor: KAWABE RYUHEI
IPC: F02B31/00
Filed: 1993-05-12
Abstract: PURPOSE:To reduce a fuel consumption amount by providing a pipe for branching an air flow just after the downstream of a butterfly valve, and opening the other end of the branch pipe to an inlet part of a cylinder of an intake pipe so as to give a turning motion to the air flow. CONSTITUTION:A throttle valve 8 is provided in the upstream part of an intake pipe 4 through a distribution part 7 and opened/closed to be associated with an accelerator pedal. An inlet nozzle of a branch flow path 9 is opened just after the downstream of a throttle valve 8. The downstream end of the branch flow path is obliquely connected to a cylinder just before part of the intake pipe. When a valve plate 11 of the throttle valve 8 is placed in an intermediate opening, a negative pressure is generated to a cylinder inlet in the downstream of the valve due to intake action. Consequently, a flow is generated in the branch flow path 9 by a difference between inlet/outlet pressures, to blow out to the intake pipe in a cylinder inlet part. This jet flow, having an angle relating to an intake pipe wall surface normal, holds angular momentum to generate a turning flow after flowing in a cylinder. Thus, a fuel consumption amount can be reduced.

IPC: H04N5/20
Filed: 1980-08-13
Abstract: PURPOSE:To achieve a pickup picture with a good picture quality through desired white clip processing at all times independently of the change in illumination. CONSTITUTION:When an output signal of an AGC detection circuit 10 is decreased, the gain of an AGC amplifier circuit 9 is increased. In this case, the base voltage of a transistor TR62 in a white clip circuit 6 specifies the white clip level, and when the video signal level to the base of a TR61 is lower than the white clip level, the TR61 is conductive and the TR62 cuts off, resulting that the video signal is obtained as it is as the output signal of the circuit 6. Inversely, when the video signal level to the base of the TR61 is higher than the white clip level, the TR61 cuts off the TR62 is conductive, and the output signal is clipped at a specified white clip level.

Title: Method for selectively generating long afterglow inside glass
Inventor: KYU KENEI
IPC: C09K11/08
Filed: 1998-04-21
Abstract: PROBLEM TO BE SOLVED: To form a long-afterglow generating region inside glass. SOLUTION: A non-resonant pulsed laser having a controlled converging point and not absorbed by glass is converged and struck into the inside of a glass containing rare earth ions such as Eu<2+> , Pr<3+> , Tb<3+> , Yb<2+> , Ce<3+> , and Mn<2+> and/or transition metal ions. The glass used is exemplified by a fluoride glass such as ZBLAN, a mixed halide glass, a silicate glass containing CdO, ZnO, an alkaline earth metal oxide, etc., an aluminate glass, or an aluminosilicate glass. As the converging point is moved relatively with the glass, a defective region formed in a specified pattern, being metastable at room temperature, and serving as a long-afterglow generating region can be formed in the inside of the glass. The pulsed laser beam is desirably one having a pulse width of 100 picoseconds.  Since a long afterglow can be generated at only the converging point and its proximity, the glass in the inside of which a long afterglow generating region has been formed in a specified pattern can be utilized as a three-dimensional display, a large-capacity limited-time memory, or the like.
