IPC: H01L21/60
Filed: 1990-04-18
Abstract: According to a method of manufacturing a semiconductor device with a semiconductor element, a wiring layer is formed on a semiconductor substrate on which a semiconductor element is formed. A first window is formed to expose a first surface portion of the wiring layer in a protective film which covers the entire surface of the semiconductor substrate. A metal film is formed on the entire surface including the first protective film and within the first window. A second window having an opening smaller than that of the first window is formed in the metal film to expose a second surface portion of the wiring layer within the first surface portion. Electrolytic plating is performed using the metal film as a current path to form a projecting metal electrode on the second surface portion of the wiring layer in the second window. Thereafter, the metal film is removed.

Abstract: A packer (10) for use in a well bore has a housing assembly (22) with an operating mandrel assembly (32) disposed therein. A packer mandrel assembly (24) is slidably connected to the housing assembly (22). During operation, the operating mandrel assembly may be actuated to cycle a tool below the packer without setting the packer. After the operating mandrel assembly and housing assembly are moved a predetermined amount with respect to the packer mandrel assembly, the housing assembly is brought into contact with a sliding shoe (172) on the packer mandrel assembly which in turn engages and deforms packer elements (26) into sealing engagement with the well bore.

Abstract: A low loss, tunable optical filter (20) comprises two ferrules (24-24) which are aligned axially with each of two adjacent end faces being provided with a wafer (30). A mirror (40) is embedded between each end face and its associated wafer, the wafer being bonded to the end face of its associated wafer. Optical fiber is disposed in a passageway which extends through each ferrule and through the associated wafer. The ferrules and associated wafers are supported to cause adjacent exposed faces of the wafers to be in predetermined spatial relation to each other. Any gap therebetween may be fixed or may be adjusted by a piezoelectric transducer system (44). The disclosed filter provides rejection ratios which are sufficiently high for frequency discrimination in frequency shift keying systems and for channel selection or switching in wave division multiplexer applications.

Abstract: The drain cleaning machine (10) comprises a frame (12) supporting a rotatable drum (56, 60) which is driven by a motor (110) through an endless belt (112). The drum (14) contains a flexible drain cleaning snake (24) which is rotatable with the drum (56, 60) and axially displaceable into and out of the drum (56, 60), and the frame (12) supports a snake feeding device (18) through which the snake (24) extends and by which the snake (24) is displaced into and out of the drum (56, 60). The frame (12) is wheeled to facilitate transportation of the machine (10) from one location to another. The drum (56, 60), drum shaft (64) and bearing (70) are constructed as a unit (14) removably mounted on the frame (12). The drive motor (110) is pivotally mounted on the frame (12) and spring biased to tension the drive belt (112) and to facilitate separation of the drive belt (112) from the drum (56, 60) to facilitate removal of the drum unit (14) from the frame (12). Stabilizer members (20) are associated with the wheels (22) on the frame (12) and are pivotal between storage and use positions in which the wheels (22) respectively engage an underlying surface (S) and are elevated above the surface (S) to stabilize the machine (10) against rolling and tipping displacement during use. The snake feeding device (18) includes three rollers which engage the snake (24) to feed the latter inwardly and outwardly of the drum in response to rotation of the drum, and two of the rollers are radially adjustable relative to the snake (24) through corresponding cam arrangements so that the feeding device (18) can accommodate snakes (24) having different diameters.

Abstract: An apparatus capable of detecting a displacement of a probe from a track of a recording medium caused by track fluctuations, vibrations at recording/reproducing period. 
     For example, a probe 1 is maintained to vibrate at frequency f in the direction perpendicular to a data train 4 at an amplitude smaller than the width of the data train 4. In this case, the amplitude of a reproduced signal of the data train changes with the displacement between the probe 1 and the data train. The envelope signal i of the reproduced signal is phase detected using as a reference signal the vibration waveform (standard signal) at frequency f o  of the probe 1, to obtain a signal proportional to the displacement from the data train. Using this signal, it becomes possible to feedback control the probe 1 so as to make it trace the data train.

The number n of the storage areas (SB) forming a storage area sequence (SBF) is to be selected with n 2<m>. The presence of information items or processes is indicated by a predetermined binary information item in the storage areas (SB). Using the method according to the invention, the storage area sequence (SBF) is divided into a plurality of substorage area sequences (TS) in which the presence of predetermined binary information items is checked and the corresponding substorage area (TS) is in each case selected as a function of the occurrence of binary predetermined information items.

Abstract: Planar display devices which have a small thickness and used as a display unit of a television set, a monitor or the like. 
     A control electrode portion for passing electrons through a given electron-passing hole selected from a plurality of electron-passing holes provided on an insulating substrate is formed by coating the insulating substrate with a conductive film and dividing them into a plurality of conductive films as control electrodes. 
     This structure obviates the mesh structure of electrons which are necessary in the case of arranging control electrodes on the insulating substrate, thereby realizing high-definition display devices with improved luminance. In addition, planar display devices provided with a surface insulated substrate produced by forming an insulating film on a conductive substrate having electron-passing holes and a plurality of separate control electrodes arranged on the surface insulated substrate, it is possible to prevent the charge-up effect which obstructs the passage of electron beams and, hence, to enhance the luminance by (1) providing a voltage applying means for applying a predetermined voltage to the conductive substrate, (2) providing a portion at which the conductive substrate is exposed between the adjacent control electrodes, and so on.

Abstract: A device for the remote control of a shower comprises a first sensor (3) having a first detection region (5). If a user enters this detection region (5) a detection circuit (7) which is connected downstream of the sensor (3) ensures that the magnetic valve (9) which controls the water flow through the showerhead (1) is opened. A second sensor (4) is also provided which has a considerably smaller detection region (6). If the user who is standing under the shower (1) moves his hand into the smaller detection region (6) of the second sensor (4), a detection circuit (10) which is arranged downstream of said sensor likewise generates an output signal. The output signals of the two detection circuits (7, 10) are combined via a circuit (11) which carries out a logic AND function and produces an output signal when both the sensor (3) having the larger detection region (5) and the sensor (4) having the smaller detection region (6) respond. This output signal is now in turn supplied to a logic circuit (12) which, at the start of this signal, determines the respective switching state of the electrically operated valve (9), like a changeover switch, and moves it to the opposite state, that is to say for example closes an open valve or opens a closed valve. <IMAGE>
