Abstract: The annular chamber separator contains a plurality of coaxial annular walls (20, 21, 22, 23), which delimit a group of annular chambers (15, 16, 17, 18, 19) nested in each other forming a serpentine flow path. If there is a danger of the lower passageways (27) blocking with sludge, the vessel (10) containing the annular chambers is inclined, so that the sludge in the annular lower baffle regions sinks to the lower end of each of them and the raised sections of the baffle regions are freed from sludge. Sludge outlets (48, 49) can be provided at the bottom (26) so that sludge can be discharged in each particular case from the lower end of the annular collection region. <IMAGE>

Abstract: An exposing apparatus adapted for exposing a completely dry photosensitive recording medium which produces no waste and uses no developing solution, and which can expose a multicolor photosensitive recording medium quickly to form a clear image free from mixture of colors, and a method for forming high-quality color images with ease using the above exposing apparatus. The exposing apparatus includes a device for transmitting light whose wavelength corresponds to a spectral response of the photosensitive recording medium, which device is interposed between an exposing light source and the photosensitive recording medium, and a device for shielding a heat ray from the exposing light source, which device is interposed between the device for transmitting light whose wavelength corresponds to the spectral response and the exposing light source. The method for forming an image uses such exposing apparatus and forms the image by exposing a heat developed photosensitive recording medium a plurality of times and then heating the exposed photosensitive recording medium substantially uniformly, the heat developed photosensitive recording medium forming a latent image on a photocuring composition by exposure and causing a component having to do with coloring or discoloring by heating to migrate within itself (the recording medium) in accordance with the latent image.

Abstract: In a method for data transfer between a plurality of memory cells and at least one input/output terminal of a semiconductor memory, and a semiconductor memory for carrying out the method, a memory cell address is defined by a control signal for a data transfer. A data transfer operation from or to the memory cells is controlled with an address control signal and an output enable control signal for defining a memory cell address with one of the two signals. A data transfer operation is subsequently initiated at a given logical linkage of the two control signals. An ensuing data transfer is controlled with the other of the two control signals.

Abstract: In an optoelectronic integrated circuit, a pin-type light receiving device (10a) and an electronic circuit device (20) are electrically connected to each other and monolithically integrated on a semiconductor substrate (1). In the pin-type light receiving device, an n-type semiconductor layer (11), an i-type semiconductor layer (12a), and a p-type semiconductor layer (13c) are sequentially formed on the semiconductor substrate (1) and sequentially formed into mesa shapes. The first mesa is constituted by the p-type semiconductor layer (13c), and the second mesa is constituted by the i-type semiconductor layer (12a). The boundary surface between the first and second mesas is formed to match the junction surface between the p-type semiconductor layer (13c) and the i-type semiconductor layer (12a). The diameter of the first mesa is formed smaller than that of the second mesa. With this structure, a depletion layer extending from the p-type semiconductor layer (13c) upon application of a reverse bias voltage stays within the i-type semiconductor layer (12a) and does not reach the surfaces of the first and second mesas to be exposed.

Abstract: An automatic cash transaction system allowing execution of a new transaction using past transaction data of the user stored in an external storage medium (5). By using the present system, the user can simply execute transactions of various kinds in a short time. The present system includes a portable external storage medium (5) storing contents of past transactions such as deposits, transfers and withdrawals, and automatic cash transaction device (1) installed in an office. When the user has specified a kind of transaction, only transaction data of the specified kind are read from the external storage device (5) and displayed on a screen and a transaction is executed on the basis of specific data selected by the user from the transaction data thus read. When the user has not specified a kind of transaction, all of usable past transaction data are read and displayed and a transaction is executed on the basis of transaction data selected by the user. If usable transaction data are not stored in the external storage device (5), the present system has a function for allowing the user to modify arbitrary transaction data stored in the external storage device (5) and execute a transaction on the basis of the modified data. <IMAGE>

Abstract: Currently, electronic imaging cameras use expensive array photodetectors instead of inexpensive linear photodetectors (30) because they cannot scan linear detectors (30) across the entire image within their exposure time and because the linear photodetectors do not capture sufficient photons to produce a high quality image. An image capture system (20) is described that has a lens (24) to form an image on an imaging plane, a detector (30) mounted to preclude translational motion, a mirror (26) for deflecting the image to the plane (31) of the detector (30), and a mechanism that moves the mirror (26) to scan the image across the detector (30). The image projection system is similar to the image capture system except that it operates in reverse and has an array of light generation elements instead of a light detector.

Abstract: Polymers suitable for chemically amplified resists based on styrene chemistry are advantageously formed with a meta substituent on the phenyl ring of the styrene moiety. Additionally, polymers for such applications including, but not limited to, meta substituted polymers are advantageously formed by reacting a first monomer having a first protective group with a second monomer having a second protective group. After polymerization, the second protective group is removed without substantially affecting the first protective group. For example, if the first protective group is an alkoxy carbonyl group, and the second protective group is a silyl ether group, treatment with a lower alcohol with trace amounts of acid transforms the silyl group into an OH-moiety without affecting the alkoxy carbonyl group.

Abstract: A communication system and method of use which integrates a paging system into the PBX communication environment providing enhance performance and capabilities. A PBX environment brings together many forms of communication: telephony conversations, voice mail, electronic mail, Fax messages, and others. The paging system, which consists of a paging server, a voice response unit, and end user paging devices, is integrated into the PBX environment making it the focal point of communications. The paging devices provide immediate and visual indication to the user of a request for callback and relative urgency for the callback, and of the arrival of other forms of communication such as a voice mail message, electronic mail, and Fax. The paging system subscriber need only look at his paging device to determine if E-Mail, Voice Mail, or facsimile messages await. Performance is also enhanced for a caller trying to reach a paging system subscriber. Callers only need to dial a single phone number, rather than a phone number for the office and a different phone number to page. Because the paging system utilizes a voice response unit, callers are informed of their options and instructed how to complete their communication.
