Abstract: It is an enema device, in which an electro-motive pump is used for adapting to different water containers, and a power supply unit in the device may be a rectifier or a car power supply; a rubber tube is connected with a rectal pipe or a washing nozzle, which is to be mounted on a stool bag before performing an enema operation.

Abstract: A writing pen having a retractible ink tube and a series of sealing disks for sealing the writing nib against vaporization or drying of ink on the nib surface when the ink tube is in its retracted position. A sliding sleeve is mounted around the ink tube to separate the ink tube from the seal assembly so as to prevent the ink from contaminating the seal assembly.

Abstract: A multi-head electro-discharging machine, in which each head member has an independent transmission assembly; the head member can move in X-axis, Y-axis and Z-axis directions by a guide screw rod; every head member can be adjusted independently for operation without intervening the others; every head member may be mounted with an electrode connector, and two head members can be operated simultaneously in a crossing manner; a plurality of head members are mounted along the rear side of a supporting frame of the machine, and one or more than one head members may be mounted on both ends of the supporting frame for further multi-processing operation.

Abstract: A canned beverage fixture attachable to the interior of an automobile; a handle portion of the fixture can be inserted in the gap between car window glass and the window frame, or it may be looped around the locking pin of the car door. The fixture comprises a fixing ring connected with a handle portion by means of a hanging belt. The lower edge of the fixing ring is formed into a barbed ring portion that facilitates insertional movement of the fixing ring around the top edge (rim) of the canned beverage.

Abstract: A remote control type of automatic control device for automobile door wherein of the car doors and its locking device is provided with a micro-switch for sensing the state of the car door and the state of the locking device. The locking devices are controlled by locking coils. The locking devices of all the car doors can be locked when a car-speed detecting circuit, a switch circuit and a delay circuit all have a specific output. When the car is parked, an unlocking trigger circuit can unlock all the locking devices. There is a receiving circuit to receive a signal sent by a remote control device. As soon as a signal is received, a trigger will be triggered. The output terminal of the trigger is connected with two NAND gates. One of the input terminals of each two NAND gates is connected one of the two contact points of a micro-switch on the main car door.
