Private data in an EEPROM (14) is erased in a data erasing procedure when pulling out an SIM card (2) from a mobile telephone (1). Before being erased, the private data is encrypted in an encryption procedure and it is transferred and recorded to an external memory (3). The private data encrypted and recorded to the external memory can be reused when the SIM card is used in another mobile telephone. Furthermore, it is possible to prevent the external memory from being left behind when the SIM card is pulled out by interfacing a lock mechanism of a card mounting section (16) with that of a memory mounting section (17).

The brake plate is located at a lower right side of the locking member. Below the brake plate are disposed an electromagnet pole shoe, an electromagnet coil, and an electromagnet core. The test button protective cap is provided with a test button having a test electric contact.

An auxiliary device for an agricultural working machine includes a hydraulic pump unit designed to pump a hydraulic fluid at a predetermined working pressure; a drive unit connected to the hydraulic pump unit that drives the hydraulic pump unit at the working pressure; a hydraulic drive having a drive-fluid inlet connected to a pump-fluid outlet of the hydraulic pump unit via a pressure line (P1, P2) and a drive-fluid outlet connected to a pump-fluid inlet via a supply line (S); and a fluid exchange device having a fluid supply line connected to the supply line (S) for a controlled supply of the hydraulic fluid from a hydraulic circuit of the working machine and a fluid discharge line connected to the supply line (S) upstream of the fluid supply line for the controlled discharge of the hydraulic fluid from the supply line (S) into the hydraulic circuit.

A front housing configuring a scroll compressor is provided in its shaft hole with a first bearing, and the front housing rotatably supports a rotation shaft. The first bearing includes a ball bearing having a plurality of balls. First and second seal rings and are provided between an outer ring fixed to the front housing and an inner ring which abuts against an outer peripheral surface of the rotation shaft. A first seal ring disposed on the side of one side surface of the outer ring is provided such that the first seal ring is in non-contact with the inner ring, and the second seal ring disposed on the side of the other side surface of the outer ring abuts against the inner ring.

The invention relates to a valve unit (10) for metering a fluid, comprising: a fluid housing (12) having a valve seat (14); a fluid passage (16) extending from the fluid inlet (18) to the valve seat (14) and from the valve seat to the fluid outlet (20); a movably mounted valve closing body (24) for controlling or regulating the flow through the fluid channel (16); a first electrode (26) and a second electrode (28), the first electrode (26) being arranged upstream of the valve seat (14) in the fluid channel (16) and the second electrode (26) being arranged downstream of the valve seat (14) in the fluid channel (16), the maximum distance between the two electrodes (26, 28) being 3 mm and/or the maximum distance between each electrode (26, 28) and the valve seat being 1.5 mm. The invention further relates to a valve assembly (50) and to a method for checking the closed state of a valve unit (10).

The invention discloses a steam condensing and backpressure switchable steam turbine power generation system and a using method thereof.

A leakproof arrangement of a chocolate fountain includes a leakproof device tightly fastened within the through hole of the basin. The leakproof device has i) a base sealed to the periphery of the through hole of the basin; ii) a plurality of support frames disposed around the base; and iii) a shaft sleeve disposed at the center of the base, the joint between the shaft sleeve and the base being tightly sealed without any gaps, the height h2 of the shaft sleeve being greater than the maximal chocolate level h1, the connection end at the top of the shaft sleeve rising above the height h2 of the shaft sleeve. In this way, the melted chocolate will never flow over the shaft sleeve such that downward leakage may be avoided. As a result, the leakage of the melted chocolate is prevented, thereby ensuring a smooth operation of the transmission element as well as a prolonged service life.
