Abstract: A bus-to-bus interface circuit maps a portion of the address space of each bus to a corresponding portion of the address space of the other bus. When a computer processor on one bus attempts to read or write access a mapped address, the bus interface circuit obtains control of the other bus and read or write accesses a corresponding address on the other bus. The interface circuit permits a bus master on the first bus to lock both buses so that it may perform several bus-to-bus data read or write operations without having to re-arbitrate for control of either bus after each operation.

Abstract: A method for fabricating a semiconductor device comprises the steps of forming an insulating layer (23) by the CVD method on a main surface of a semiconductor substrate (21), fluidizing the insulating layer by heat treatment, unifying a thickness of the insulating layer, opening contact holes in desired points of the insulating layer (23), and forming conductor contacts for interconnection on the contact holes. The insulating layer has a uniform thickness in any area on the semiconductor device, so that over-etching of the insulating layer (23) in opening contact holes can be prevented, and the step coverage is well improved.

Abstract: A pressure ranging from 50 Kgf/cm² to 800 Kgf/cm² is applied to a powder of fine particles of activated carbon (1,2,3), and while the pressure is being applied to the particles, pulse voltages are applied between the particles for producing electric discharges between the particles, and the particles are kept at a temperature ranging from 700°C to 1000°C, thereby sintering the fine particles of activated carbon to form an electrode of a porous sintered body. Two such electrodes (32) are impregnated with an electrolyte to produce polarized electrodes, and a separator (33) is sandwiched between the polarized electrodes, thus forming an electric double layer capacitor.

Title: Image reading device
Inventor: TAKAMIZAWA SHIRO
IPC: B65H3/52
Filed: 1990-12-11
Abstract: An image reading device having a feed roller and a document-separating member for separating and feeding one document at a time from a stack of documents on a hopper, and an image sensor for reading each document being transported through a suitable document transport path inside the device. The document transport path is inclined downward for a short distance immediately downstream of the feed roller and the document-separating member, then is bent in a near-horizontal direction, stretching substantially straight. This structure reduces the overall height of the device. A rotatable pushing member for pushing the document-separating member against the feed roller has a document guide surface which is located downstream of the document-separating member and which protrudes beyond the putative extension of the document contact plane at the end of the document-separating member, the pushing member thereby constituting a bend of the path. Because the document guide surface supports a document being fed while bending along the path, the document does not hit and raise the document-separating member to disrupt its document-separating action.

Abstract: An apparatus which develops a latent image recorded on an image receiving member with marking particles. A chamber (78) in a developer housing (80) stores a supply of charged marking particles. The marking particles having a charge distribution. A donor roll (74) is positioned in the chamber (78) of the housing (80) to transport marking particles closely adjacent to the latent image to develop the latent image. A rotating, elongated member (44) moves the marking particles. An electrical bias is applied between the elongated member (44) and the donor roll (74) to selectively attract marking particles from the elongated member to the donor roll. The marking particles attracted to the donor roller (74) have a charge distribution with a selected range. The range of the charge distribution of the marking particles attracted to the donor roller (74) is less than the range of the charge distribution of the marking particles being moved by the elongated member (44).

Abstract: A preparation for transdermal drug administration comprising a flexible backing layer and a pressure-sensitive adhesive layer containing a local anesthetic in a proportion of 40-65 weight%. Since the ratio of the amount of the undissolved local anesthetic (Ac) to that of the dissolved local anesthetic (As), Ac/As, in the pressure-sensitive adhesive layer is determined to be in the range of 0.1-1.8, the preparation for transdermal drug administration of the present invention is superior in self-adhesiveness and leaves no adhesive material upon removal from the skin. In addition, burst-like release of the undissolved drug from the pressure-sensitive adhesive layer immediately after application to the skin permits rapid appearance of the anesthetic effect, which enables wide clinical application of the preparations of the present invention.
