Title: Connected structure of plastic pipe
Inventor: KODA OSAMU
IPC: B29C65/30
Filed: 1985-12-19
Abstract: PURPOSE:To prevent that an adhesive is squeezed out in a pipe and the fluid in the pipe is contaminated with the solvent of the adhesive by combining connection by using an adhesive with welding-connection by means of an electric heating coil. CONSTITUTION:A cylindrical surface 22 of a smaller diameter is formed on the apex of a spigot 21. An electric heating coil is wound around the cylindrical surface and the backward outer surface is coated with an adhesive 3. The spigot is thereafter pushed in a faucet 11 and the apex of the spigot is pressed against the step part of a stopper 12 formed at the inner part of the faucet 11. An electric current is sent to the electric heating coil drawn outside to heat both the inner surface of the faucet 11 and the apex surface of the spigot 21, which are thereby melted to fuse each other. As the connection with the adhesive is done only on the opening side of the faucet, the adhesive 3 is not squeezed out into a pipe from the inner part of the faucet 11 and the apex of the spigot 21 when the connecting operation is carried out. There is no possibility that the solvent of the adhesive is ooze out as the inner part of the faucet and the apex of the spigot are fused with each other.

Title: Display device
Inventor: HARADA SHIGEYUKI
IPC: G09F9/30
Filed: 1989-11-02
Abstract: PURPOSE:To suppress a current flowing to a display area, to miniaturize a device and to reduce the cost thereof by making the polarity of a voltage impressed on the first display area of an image display part and the polarity of a voltage impressed on the second display area mutually reversed. CONSTITUTION:In a P frame, the voltage 0V is impressed on an electrode XA on a data side from a data side driving circuit 260 as a modulation voltage corresponding to light emission. On the other hand, since display data UData and LData which is respectively given to the driving circuits 260 and 270 are inverted by reversal control rotation, the voltage VM is impressed on an electrode XB from a power source circuit 280 through the circuit 270 as a write voltage. At this time, the voltage having a positive polarity VW + VM is impressed on an electrode YA on a scanning side from a power source circuit 310 through a driving circuit 220 as the write voltage by switching a switching circuit 340a. Besides, by switching a switching circuit 340b, the voltage -VW having a negative polarity is impressed on the electrode YB on the scanning side from a power source circuit 330 through a driving circuit 240 as the write voltage. Thus, light is emitted from picture elements A and B.

Title: Self diagnosing device in exhaust gas recirculation controller
Inventor: ONO KENICHI
IPC: F02M25/07
Filed: 1988-11-11
Abstract: PURPOSE:To prevent the erroneous judgement by installing the second control means which prohibits the judging operation by a judging means and prolongs the opening/ closing operation time of an opening/closing means by the control means, when a temperature detecting means detects the rise of the temperature where bad influences are given onto a diaphragm. CONSTITUTION:A control circuit 17 prohibits the judgement operation in the self diagnosis when the temperature detected by an intake temperature sensor 7 is below a prescribed value (e.g., 0 deg.C or less) where bad influences are given into an EGR valve 13 and the diaphragm of a modulator 15. When the intake temperature is over 0 deg.C, it is judged if the operation is within the operation region where exhaust gas recirculation control is carried out or not, from a map according to the intake pressure at present and the engine revolution speed, and when the operation-enabled region is judged, a solenoid valve 16 is energized, and the negative pressure in a suction pipe 2 is applied into the modulator 15, and the valve 13 is opened, and exhaust gas is allowed to recirculate into the suction pipe 2. Therefore, the erroneous detection of the anomaly of the exhaust gas recirculation controller which is caused by the hardening of the diaphragm due to low temperature can be prevented.

Title: Lead storage battery
Inventor: MORIMOTO YOSHINARI
IPC: C22C11/08
Filed: 1985-12-19
Abstract: PURPOSE:To reduce the fluctuation in the composition of a lead alloy of low antimony content in the melting and remelting of the alloy, by adding 0.02% or less by weight of copper likely to generate an intermetallic compound, to the lead alloy of 2% or less by weight in antimony content to make a base of the alloy. CONSTITUTION:Generally, the lower the antimony content of a lead alloy is, the larger the fluctuation of a eutectic region is. A region of such kind also fluctuates much, depending on the distribution of the composition of the alloy. Therefore, it is important to minimize the fluctuation in the composition of the molten lead alloy for casting, in enhancing the productivity of the casting. If the antimony content of the lead alloy is not higher than 2% by weight, the generation of dross is sharply fast in comparison with a conventional lead alloy. However, the addition of copper, which is not quite effective for a lead alloy of 3-5% by weight in antimony content, is effective to stabilize the composition of the lead alloy in the casting. For that reason, a positive electrode base is made of the lead alloy which has an antimony content of 2% or less in weight and to which 0.02% or less by weight of copper is added.
