Abstract: The invention relates to a temperature-stable inductive proximity switch having a transistorized resonant circuit oscillator. The feeding into the emitter-to-collector circuit of the resonant circuit transistor T1 of a balancing current, which depends on the individually determined temperature of the resonant circuit transistor T1 and the individually determined temperature of the resonant circuit coil, ensures that the proximity switch is temperature-stable with respect to its switching distance for every adjusted basic current.

Abstract: 2.1 The axle load of such a drive axle can be described by the spring deflection of the suspension spring and the pressure of the lifting bellows. A previously described device has a signal body which can be displaced axially by the pressure and rotated by the spring deflection. A three-dimensional characteristic diagram is arranged on the signal body and determines for each constellation of rotational position and axial position the insertion depth of the slide of an electrical displacement sensor into the stator and thus determines the axle load signal to be obtained. Because of the signal body with the three-dimensional characteristic diagram the known device constitutes a complex solution. 2.2 In order to simplify the known device, the present invention proposes the replacement of the three-dimensional characteristic diagram by a two-dimensional contour (20, 21) and a displacement capability of the stator (25) of the displacement sensor (24) as a function of the pressure of the lifting bellows (1). As a result, a pressure-dependent adjustment of the insertion depth is superimposed on the adjustment of the insertion depth of the slide (22) by the contour (20, 21). The preferred area of application is vehicle technology. <IMAGE>

Abstract: The invention relates to a method for stabilizing alkaline cleaning baths for Si wafers containing hydrogen peroxide (H2O2), the wafers being intended, in particular, for semiconductor devices. The method ensures in a simple manner that the H2O2 concentration of the bath decreases to values at which the Si wafers are incipiently etched. This is achieved by measuring the potential of an Si wafer in the bath with respect to a reference electrode (calomel) and increasing the H2O2 concentration in the bath again if the potential is markedly displaced to more negative values. <IMAGE>

Abstract: According to the invention, if there is a defective column among the memory cell columns in the memory cell array, all bit lines sharing the same I/O data lines as such a column are separated from the I/O data line regardless of the column address, and instead a group of spare bit lines disposed corresponding to each column address and selected according to the column addresses is electrically connected to the I/O data line. 
     In this structure, the bit lines are disposed by dividing into corresponding I/O data line, and if there are defects extending in two or more rows, as far as they are within a block of same I/O data line, all defective memory cells can be replaced by the memory cells in the spare column. Therefore, while minimizing the increase of chip area and lowering of operating speed in the multiple-bit organized memories, a redundancy circuit of high defect repair efficiency may be realized.

Abstract: A new method is used to fabricate an isolation trench to prevent spurious epitaxial growth at the top edge of the trench opening and at pin holes in oxide over the active area. The method involves etching a deep trench into a semiconductor wafer that is patterned with a mask oxide layer, and then depositing a low temperature oxide, followed by growing a thermal oxide layer under the mask oxide and in the trench. When the oxide at the bottom of the trench is removed to provide a seed for the growth of selective epitaxial silicon, an oxide layer thick enough to leave a protective coating over the active area and at the trench opening is provided which prevents spurious epitaxial silicon growth.

Abstract: A developing device using a one-component developer composed of toner particles, which device comprises a vessel for holding the developer, and a developing roller rotatably provided within the vessel so that a portion of the roller is exposed therefrom and faces a surface of an electrostatic latent image carrying body to form a developing area. During a rotation of the roller, the toner particles are entrained by a surface of the roller to form a developer layer therearound, and are carried to the developing area for a development of an electrostatic latent image formed on the latent image carrying body. The roller and the latent image carrying body are reversely rotated such that the surfaces thereof move upward at the developing area. A blade member is provided within the vessel and resiliently engaged with the roller for regulating a thickness of the developer layer, and is disposed below the roller to prevent a leakage of the toner particles from the vessel at an underside of the developing roller.

Abstract: A high efficiency thermal interposer (150) comprising a first hollow disk (160) and second hollow disk (161), held together by thermally isolating fasteners (162, 163). The fasteners keep the disks from touching one another. In an illustrative embodiment of the invention, the first disk is the low temperature disk portion and the second disk is the high temperature disk portion of the heat shield. Furthermore, according to a preferred embodiment of the invention, the space between the disks is filled with small thermally conductive particles (185) (e.g., stainless steel spheres) which are in thermal contact with the high temperature disk but which are not in contact with the low temperature disk. The thermal interposer/heat shield includes means (135) for introducing cold jets of air into the cavity containing the particles, means for circulating (169) the air therebetween, and means through which the air can exit from the cavity to carry away the heat picked up from the particles inside the cavity. The novel thermal interposer has a low mass, is compact and can achieve a temperature drop that will permit high powered HAT devices to be used in conjuction with temperature sensitive electronic orientation means, such as robot arms.
