Inventor: GRUTTER ROLAND DR
IPC: C25D13/10
Filed: 1989-09-08
Abstract: Pitting in electrodeposition coatings has hitherto been prevented by adding pigment or acrylate resins. This adversely affected the adhesion of the following paint. The object is to provide novel electrodeposition coatings which ensure good adhesion of the following paint and good stone chip resistance. This is achieved by an electrodeposition coating composition which contains an aqueous dispersion of a cathodic or anodic deposition resin and polymer microparticles. The polymer microparticles have a glass transition temperature of below +10 DEG C. A good antipitting effect is thus achieved without impairing the adhesion of the following paints with good stone chip protection. The coating compositions are particularly suitable for the preparation of primers for motor vehicles.

Abstract: A contact-free floating-gate non-volatile memory cell array (1) and process with silicided NSAG bitlines (2,4) and with source/drain regions (SD) buried beneath relatively thick silicon oxide (5). The silicided bitlines (2,4) have a relatively small resistance, eliminating the need for parallel metallic conductors with numerous bitline contacts. The array (1) has relatively small bitline capacitance and may be constructed having relatively small dimensions. Isolation between wordlines (13) and between silicided bitlines (2,4) is by thick field oxide or by P/N junction or trench isolation. Wordlines (13) may be formed from silicided polycrystalline or other material with low resistivity. Coupling of programming and erasing voltages to the floating gate (8) is improved by extending the gates (8) and (10) over the thick field oxide and perhaps by using an insulator with relatively high dielectric constant between the control gate (10) and the floating gate (8). The resulting structure is a dense cross-point array of programmable memory cells.

Abstract: A cabinet (1) comprises access openings, which are displaceable, for example, with the aid of sliding roller doors (3, 5), for access to the interior of the cabinet (1). In the interior of the cabinet (1) there are electric motor driven parts, for example for setting down index card boxes (9) which are moved past the access opening (7) in a paternoster-type movement. It is guaranteed by a safety device that the movement only takes place with the coverings (3, 5) closed. The safety device provides for the coverings (3, 5) each to be fitted with an electric circuit section (21a, 21b) which are removed from a safety loop (17, 19) when the coverings (3, 5) are opened. By this means, a stoppage of the moved parts (9) is inevitably brought about. The electric circuit sections (21a, 21b) have contact parts (23a, 23b) which can be brought into engagement in corresponding contact elements (15a, 15b) which are attached to the housing (1). The cabinet (1) offers the advantage that it is largely protected against manipulations on the safety device since the removal of a complete electric circuit section (21a, 21b) cannot be carried out using simple measures, such as jamming a contact by means of a match, paperclip or the like. <IMAGE>

Abstract: A structure of an A/T (automatic transmission) control device for a vehicular transmission is disclosed in which when the shift lever (1) for controlling the A/T is pivoted at a position at which a positioning pin (7) is engaged with a parking range P, a solenoid pin (15a) pushed and rotates a rotary bush (14) supported on a peripheral surface of a rotary bush by means of a force of a spring within the solenoid (15) so that a recessed groove (14a) of the rotary bush (14) is deviated from a position of the positioning pin (7). Therefore, even if control button (13) (installed at an upper end of the shift lever (1)) is operated, the positioning pin (7) interferes with the upper plane of the rotary bush (14) and is not lowered any more. Consequently, no deviation from the range P occurs. Next, when a vehicular ignition switch (22) is turned to ON and foot brake is operated, the solenoid (15) is turned to ON. The solenoid pin (15a) pulls and rotates the rotary bush (14) against the spring force of the spring installed within the solenoid so that the position of the recessed groove (14) of the rotary bush becomes the same as the position of the positioning pin (7). When the control button (13) is operated, the positioning pin is moved out of the P range. Thus, it becomes possible to move the shift lever (1) at any one of the ranges other than the P range. The solenoid (15) is again turned to OFF a constant period of time after the solenoid is turned to ON with the foot brake is depressed.

Abstract: A fiber optic telecommunication system has master site linked to a plurality of subscriber interface sites by a single pair of optical fibers. Downlink messages are transmitted in a continuous TDM format over a first optical fiber from the master site to subscriber interface sites, and in a burst mode TDMA format over a second optical fiber from the subscriber interface sites to the master site. Each subscriber interface site is coupled to the optical fiber link by way of a multiple fan-out fiber coupling pedestal at a common location on the fiber pair. To prevent collisions between successive uplink bursts from the subscriber interface sites, a guard band separates successive uplink messages from one another. The guard band duration accommodates optical fiber transmission distance between the common location on the uplink optical fiber and the subscriber interface site whose differential optical fiber transmission distance from the common location is greatest. A subscriber location has a television decoder associated with the subscriber's television set, through which television channel selection signals are input by the subscriber for transmission from the subscriber interface site to the master site. Power is provided by way of a replaceable battery pack, housed in a subterrestrial bell jar configuration, effectively insulating the battery pack from extreme temperature changes and the intrusion of moisture.

Abstract: An electric double layer capacitor employs a paste electrode (33) between collector electrodes (34). The paste electrode (33) is compressed under a small load because the collector electrodes (34) are pressed by compression plates (21) in only an area corresponding to the paste electrode (33). With the paste electrode (33) thus compressed, the internal resistance of the capacitor is reduced and the capacitance of the capacitor is stable. The electric double layer capacitor comprises a stack of basic cells (30) or capacitor elements. The basic cells (30) are held closely together by a bolt (23) which extends through central holes (31) in the basic cells (30) and interconnects the compression plates (21), so that the basic cells (30) are compressed under a uniform and appropriate pressure.
