Patent JP-H02294595-A (JP)
Title: Vertical shaft pump
Inventor: NISHIZAWA SADAHIKO
IPC: F04D15/00
Filed: 1989-05-02
Abstract: PURPOSE:To simplify structure by a method wherein an inverted U-shaped air feed pipe is connected to a through-hole through which an impeller suction part is communicated to an external part, and a return part has an open end located to a lowermost water level and in a position lower than the through-hole and in a position higher than a suction head available when a maximum negative pressure is generated at the impeller suction part. CONSTITUTION:When a water level is lowered to a lowermost water level LWL and an open end 9A of an inverted U-shaped air feed pipe 9 is opened in the open air through pumping operation, air is sucked through the open end to a suction part 1A of an impeller 1. Water in a coupling pipe 7 and a suction bell mouth 3 is dropped through vacuum break, and switching to air operation is effected. This operation prevents the occurrence of an air suction vortex and breathing phenomenon, and waiting operation is effected in a stable state. When a water level is restored to a value higher than LWL and the open end 9A is submerged, switching to pumping operation is effected by means of the negative pressure of the suction part 1A generated by a self-breathing effect. Since a return part 9B of the air feed pipe 9 is located in a position higher than a suction head available when a maximum negative pressure is generated at the suction part 1A, water is not sucked through a through-hole 8 to the suction part 1A, and pumping capacity is not lowered.

Title: Image forming device
Inventor: NAKAYAMA TOMOFUMI
IPC: G03G15/00
Filed: 1992-05-07
Abstract: PURPOSE:To accurately detect an overcurrent generated when a picture forming device becomes abnormal by switching the target value of the overcurrent to a value conforming with each state in accordance with the state of the image forming device. CONSTITUTION:When the device is initialized, a target overcurrent value switching signal 111 is sent from a control unit and a selector 206 is set to a target value I2 side, namely, to a storage circuit 205 side. The then current value is about 1-2A. On the other hand, since the target value I2 is set at 3A, no overcurrent can be detected when the overcurrent has a normal standby-type waveform. However, when an abnormal waveform is generated due to a slight short, etc., an overcurrent detecting unit 203 can detect the abnormal waveform, sine the abnormal current exceeds the target value I2. As a result, a power unit 102 disconnects a power source 103. When copying operations are started, the selector 206 is switched to another target value I1 side and the target value is set at 10A. During the copying operations, any electric current can be detected, because the current fluctuates between about 3A and 8A. When the copying operations are completed, the selector 206 is again switched to the target value I2 side.
