Title: Method for injection-molding resin covering layer on inner surface of pipe joint and mandrel therefor
Inventor: TANABE KATSUE
IPC: B29C45/14
Filed: 1988-11-18
Abstract: PURPOSE:To prevent resin covering layer from being separated at the removal of a sprue by a method wherein the longitudinal section of lateral runner is formed to be tapered so as to expand toward a longitudinal runner in order to make the tapering angle in the longitudinal section of the lateral runner at the position coming into contact with a gate at the specified angle. CONSTITUTION:On the method and the mandrel for injection-molding elbow, since a gate is arranged on the inner surface side of the concave curved part of a pipe joint, a sprue left after injection molding must be removed by being pulled off without causing the separation of the resin covering layer from the inner surface of the pipe joint. Further, on the method and the mandrel for injection-molding elbow or tee, the longitudinal section of a lateral runner 12 is tapered so as to expand toward a longitudinal runner 11 and, at the same time, the tapering angle on the lateral runner side is formed larger than that on the resin covering layer side by 2-30 deg.. Furthermore, on the method and the mandrel for injection-molding socket, the longitudinal section of the lateral runner is tapered so as to expand toward the longitudinal runner and, at the same time, its tapering angle is formed to be 92-120 deg.. When a sprue is sheered off under the state just mentioned above, the sprue is pulled off just at the gate or under the state that more material even on the resin covering layer side with respect to the gate is sheered off, without decreasing the flow resistance of the pipe joint.

Title: Flow regulating valve
Inventor: OKADA SADAO
IPC: F16K31/04
Filed: 1993-11-22
Abstract: PURPOSE:To smooth valve disc operation and prevent lowering of regulation precision by a method wherein the rear base end part of a cylindrical valve body is caused to effect airtight slide over the inner peripheral surface of the flow passage of a valve chamber and the valve part of a valve body part is positioned facing a valve seat part situated upper stream from an outlet, and a distance between the valve seat part and the valve part is regulated through movement in an axial direction of the valve disc. CONSTITUTION:A valve disc 1 is moved forward and backward according to an input signal, a distance between a valve part 13 and a valve seat part 23 is changed, and the opening of the valve disc 1 is regulated. Since, during axial slide of the valve disc 1, the outer periphery of the base end part of the valve disc 1 is caused to perform airtight slide over the inner peripheral surface of a valve chamber flow passage 20, even through the valve disc 1 is formed in the shape of a cylinder, no flow from other than a flow passage running between the valve part 13 and the valve sea part 23 is generated. Further, since the rear space 29 of the valve disc 1 is communicated to the downstream part of the valve disc 1, even when the rear space 29 is expanded and contracted along with movement of the valve disc 1, a pressure in the rear space 29 is neither increased nor decreased. Thus, a useless working force through pressurization and reduction of the pressure of the rear space 29 is eliminated. The valve body 1 is smoothly operated by a transmission device and since the outer periphery of the base end of the valve body 1 is caused to effect airtight slide over the inner peripheral surface of the valve chamber flow passage 20, flow rate regulation precision is not lost.

Title: Tablet device
Inventor: TERANISHI YUKIHIDE
IPC: G06F3/0488
Filed: 1994-11-28
Abstract: PURPOSE: To prevent a pen from being lost or carried away by providing a pen recognizing circuit for outputting a signal when the intensity of signals from the respective loop coils of an antenna coil group gets lower than a designated value and its time exceeds a prescribed time. CONSTITUTION: When a cordless pen 1 is moved to a position largely distant from a main body 2 of a tablet, it is impossible to detect the position of the cordless pen 1 by an antenna coil group 6. After the lapse of a fixed time from that the detection became impossible, a pen recognizing circuit 11 transmits a signal to a driver 13 and the driver 13 generates a warning sound by driving a loudspeaker. Besides, even when the position of the cordless pen 1 can be detected, the pen recognizing circuit 11 checks the strength of signals from the respective loop coils of the antenna coil group 6 when the cordless pen 1 is positioned on a pen rest, and when the strength is insufficient, the warning sound is generated through the driver 13 by driving the loudspeaker.

Title: Image forming device
Inventor: KUZUMI TOORU
IPC: G05F1/10
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To avoid leak and to make continuable printing operation by providing an output switching means making the output of a high-voltage power source drop to a previously decided at value when an output abnormality detection means detects an abnormality. SOLUTION: When the occurrence of the leak is detected by a leak detection circuit 42, a leak signal S4 is transmitted to a control circuit 5, and the number n(=1) of occurring times of the separation leak is recorded in a memory 7. Simultaneously, an output switching signal Q4 is transmitted to the high-voltage power source 41 from the circuit 5 so as to make the output of the power source 41 drop to the set value lower than an initial value. Since high-voltage output is automatically made to drop when the leak occurs, the leak is stopped, and the printing operation is continuously performed again. Thus, the performance of a separation discharger 4 is kept longer than in the conventional one, and the number of repairing times is made small. When the main cause of the leak is removed by repair and performance of the discharger 4 is restored to an initial state, the high-voltage output can be restored to the initial value.

Filed: 1987-11-19
Abstract: PURPOSE:To increase breakdown strength in input protection by a method wherein the gate electrodes of two transistors are connected to a ground electrode and their drain electrodes are connected to an input pad and an input gate electrode. CONSTITUTION:The drain electrodes of two N-channel MOS transistors built in a P-well are connected by an aluminum lead 6 to an input pad 20 and an input gate electrode. Gates electrodes 3 and 4 are both connected to a ground wiring 8 through a second polycrystalline silicon layer 9. Source electrodes are connected to a power source and a ground electrode pad through aluminum leads 7 and 8. In this design, when a surge voltage is applied to the input pad 20, resistance is lower in the line from a drain to a power source or to the ground level than in a design wherein connection is established between a source electrode and a power source or the ground by using a diffusion layer or a polycrystalline silicon layer. Escape of electric charges is easier in such a design, which increases breakdown strength in input protection.
