Abstract: Direct electrostatic printing apparatus including structure (12) for delivering developer or toner particles to a printhead (14) forming an integral part of the printing device. The printing device includes, in addition to the printhead, a conductive shoe (16) which is suitably biased (38) during a printing cycle to assist in the electrostatic attraction of developer through apertures (36) in the printhead onto the copying medium (30) disposed intermediate the printhead and the conductive shoe. The structure (12) for delivering developer or toner is adapted to deliver toner containing a minimum quantity of wrong sign and size toner. To this end, the developer delivery system includes a conventional magnetic brush (18) which delivers toner to a donor roll structure (24) which, in turn, delivers toner to the vicinity of apertures in the printhead structure.

Abstract: In the case of previous methods for the acquisition of a control signal for automatic track following in the playback mode of a magnetic recording apparatus with rotating magnetic heads, during the scanning of the individual tracks the signal levels of crosstalking pilot signals which are recorded in the respectively adjacent tracks are measured and subsequently subtracted from one another. However, such a control only operates satisfactorily if the signal levels of the pilot signals recorded and to be sampled do not display fluctuations caused by the apparatus or the tape. The novel method is intended to ensure error-free control even in the case of such fluctuations. In the case of the novel method, instead of the customary practice of forming the difference, the quotient of the measured crosstalk levels is formed. Magnetic recording apparatuses with rotating magnetic heads.

Inventor: KAWAMURA HIDEO
IPC: F02B77/11
Filed: 1988-05-25
Abstract: The heat-insulating piston structure (10) according to the present invention is formed by fixing a piston head (4), which consists of a material the coefficient of thermal expansion of which is substantially equal to that of a ceramic material, to a piston skirt (2), and setting a thin, flat plate (5) portion of a ceramic material on the whole of the flat surface of the piston head which is on the side of a combustion chamber via a heat-insulating member. Accordingly, the piston (10) can be formed so that it has excellent heat-insulating character­istics and high thermal resistance, deformation resistance and corrosion resistance. Especially, the thin plate portion of a ceramic material (5), which is exposed to a combustion gas, can be formed to the smallest possible thickness to reduce the thermal capacity thereof greatly. Therefore, the temperature of the wall of the combustion chamber varies easily with that of the combustion gas (in other words, the amplitude of the temperature of this wall becomes large). Consequently, a difference between the temperature of the thin plate portion of a ceramic material and those of the gases (combustion gas and suction air) becomes small momentarily, so   that the heat transfer rate of the thin plate portion decreases. This causes a decrease in the quantity of heat which the suction air receives from the wall surface. As a result, the suction air smoothly enters the combustion chamber without being expanded therein. This enables the suction efficiency and cycle efficiency to be improved.

Abstract: In known diplexers for separating a total frequency range into at least two part-frequency ranges or connecting these together, via which a remote power feeding current is fed into the connecting point of a branch, constructed, for example, as high-pass filter, for a higher part-frequency range for supplying an active component with operating current, this branch exhibiting at least one series capacitor and a shunt inductance connected to its connecting point, the high-pass filter is bypassed by a choke (D) for the transmission of the remote power feeding current (Figure 1). Due to the inter-turn and stray capacitance of this choke (D), the transfer characteristics of the diplexer are greatly impaired at high frequencies and/or feed currents. To avoid or at least to minimise this disadvantageous effect, it is proposed that the shunt inductance (L7) connected at the connecting point (A2) of the branch (4) for a higher frequency range (first satellite intermediate frequency range) is connected to earth via a bypass capacitor (C7) and the junction point (P1) of these two reactances (L7, C7) is connected via a choke (Dr1, Dr2) to a circuit point (P2) of a branch (3) for a lower part-frequency range (40 to 860 MHz), which is connected via at least one inductance (L1, L2, L4) to the separating point (A) or junction point of the diplexer (1). <IMAGE>

Abstract: A patterned microwave interactive element and laminate including a patterned microwave interactive element for use in forming food packaging materials that may be employed to store and subsequently cook the food stored therein are provided. The pattern of the microwave interactive element is selected to focus the heat generated to predetermined areas of the food contained in the packaging. Areas where the microwave interactive element has been deactivated may be formed by a variety of methods, such as by demetallization, by the application of an inactivating chemical, by mechanical means and the like, to create a preselected pattern of inactive areas relative to the active areas, thereby controlling the temperatures produced in different sections of the packaging material. Optimum browning and/or crisping of the microwave heated food product may be achieved by selecting a pattern of microwave interactive and inactive areas tailored to specific food products.

Abstract: Dynamic logic units utilize magnetic cores (3) of rectangular hysteresis loop material wound with an input winding (9), a pair of output windings (35, 41) connected to a CMOS flip-flop (17), and a d-c control winding (13). With a d-c current on the control winding, output pulses which alternately switch the flip-flop (17) to produce a square wave output which matches the input are generated. In a first embodiment, the output windings are in the form of a center-tapped winding (35, 45, 41) with the center tap (45) grounded to provide a low impedance discharge path for the capacitors (33, 39) in grounded R-C filters on the inputs to the flip-flop (17) which suppress voltage spikes; output windings on separate magnetic cores which share an input windings but only one of which has a control winding, are connected in opposition to eliminate the switching spikes in the signal applied to the flip-­flop.
