Abstract: The present invention relates to silk screen printer which comprises a cylindrically curved printing table adapted for the application of print onto print material; a stencil frame and stencil arranged for reciprocating movement in response to the reciprocating movement of the printing table (2); a squeegee arrangement for pressing the stencil against the printing table and therewith transfer print to print material located between the printing table and the stencil; and a gripper (8) which coacts with the printing table and which grips the leading end part (3a) of the print material(3), as seen in the direction of movement, at least during part of a printing sequence. 
     The gripper (8) is pivotally mounted on the printing table (2) and extends in the direction of longitudinal, curved extension of the table, the gripper (8), in a registered position, being pressed against a stop means (13) such as to register the gripper in relation to the chassi (10) of the printer, it being possible to effect this registration while disregarding the stop position of the stencil frame and the printing table (2). 
     The printer also includes a forked roller arrangement (30) which is effective in retarding movement of the gripper (8) towards a registered position and in accelerating the gripper (8) away from this position. 
     It is proposed that Figure 3 is published together with abstract.

Abstract: An equal voltage is applied to a shielding case (11b) and a screen grid (28) when a normal mode is set, while a switch (46) is changed over to connect the shielding case (11b) to ground when a photo mode is set. Therefore, part of a discharge voltage from a corona discharger (11) is passed to ground in the photo mode. It is therefore possible to make the surface potential of a photosensitive body (10) in the photo mode in which the shielding case (11b) is grounded lower than that in the normal mode in which the shielding case (11b) of the corona discharger (11) is placed at a potential corresponding to an output direct-current voltage of a high-tension transformer (76). As a result, the halftones of photographs can be reproduced effectively.

Abstract: A transformer apparatus uses SCR devices (152,153; 252,253) as tap switching elements for a tapped winding (113,117) of a transformer (100). A snubber circuit (180,280) is connected in parallel with each tap switching element. Current flow in a snubber circuit associated with each SCR device is monitored to determine the present switched state of that SCR device. This monitored current flow is utilized by control circuitry (130) to permit turn on of an SCR device only when all of the tap switching SCR devices are presently non-conducting.

Abstract: A process for transferring information including a source or destination address between two nodes in a network via data switching logic. The switching logic must decode commands and addresses in order to adopt the proper configuration so that the commands and addresses can be forwarded from one system resource to another system resource. A read or write address is transmitted to the switching logic and decoded in order to configure the switching logic. The same read or write address is then retransmitted to the switching logic for forwarding to the appropriate system resource. As a result, there is no need for extra storage logic in order to retain read and write addresses while the switching logic is being configured.

Title: Device and method for defect handling in semi-conductor memory
Inventor: GROSS STEPHEN
IPC: G06F12/16
Filed: 1990-09-19
Abstract: A solid-state memory array such as an EEprom or Flash EEprom array is used to store sequential data in a prescribed order. The memory includes a first information list containing addresses and defect types of previously detected defects. The defects are listed in the same prescribed order as that of the data. Only a simple controller is required to reference the information list so that writing or reading of the data will skip over the defective locations in the memory. New defects may be detected during writing by failure in verification, and those new defects will also be skipped. The memory also includes a second information list maintained by the controller. As data is written to the memory, addresses of file-markers and defects detected by write failure are entered into the list in the same prescribed order. This second list is referenced with the first list by the controller in subsequent reading to skip over both the previously and the newly detected defects.

Abstract: Treatment coil (10) for an electromagnetic therapy apparatus, which coil has an approximately oval cross-section with a large and a small diameter (a and b respectively) and can be used to treat the trunk of the human body with low-frequency magnetic alternating fields. The cross section of the treatment coil is asymmetrical relative to the large diameter (a), in particular it is curved to a greater extent in the upper part than in the lower part. A treatment coil shaped in this way is, for the patient being treated, considerably more comfortable than the known treatment coils with circular or elliptical cross-section. <IMAGE>

Abstract: Afterglow in a luminescent material in which a significant factor in afterglow is the release of holes from hole traps in the scintillator material is substantially reduced by adding a hole-trapping species to the scintillator composition which successfully competes with the hole traps in the basic scintillator composition. In gadolinium gallium garnet activated with chromium, the addition of cerium, terbium or praseodymium reduces afterglow in this manner.

Abstract: An output from a solid state image sensing device spatially modulated by a color filter is A/D converted and stored in a field memory. Digital signals read from the field memory during electronic zooming are successively delayed by 1 H period by means of first, second and third 1H delay elements connected in series. The output from the field memory and outputs from the first, second and third 1H delay elements are separated into luminance components and line sequential color components by first to fourth Y/C separating circuits, respectively. A first set of three primary color signals are calculated based on outputs from the first, second and third Y/C separating circuits, and a second set of three primary color signals are calculated based on outputs from the second, third and fourth Y/C separating circuits. Three primary color signals corresponding to a new display point formed along with the execution of electronic zooming function are formed based on the calculated two sets of three primary color signals, and a luminance signal corresponding to the new display point is formed based on outputs from the first and second delay elements.

Abstract: A drive circuit having, in addition to a fault discrimination operational circuit for detecting an overcurrent of the current sense IGBT (Q1), a capacitor (C2) operatively connected in parallel to the gate-emitter of the current sense IGBT, and a transistor (T4A) for discharging the capacitor via a resistor (R2). In case of short-circuit fault, an overcurrent is detected by the fault discrimination operational circuit (100), and the transistor is turned on via the operational circuit. The gate voltage of the IGBT is gradually declined to turn off the IGBT. This enables the IGBT to be protected from a transitional overvoltage across the collector and emitter of the IGBT.
