Patent CA-2086927-A1 (CA)
Title: Method and device for purifying air
Inventor: LARSSON OLA
IPC: B01D53/72
Filed: 1991-06-27
Abstract: A method and a device designed to clean air and water as well as to recover purified process water with reference to a drier (1) in a particle board or fiber board production process. The polluted air from the drier is fed through a scrubber (3) and is freed in the scrubber from the main part of solid and gaseous contaminants, before it is discharged into the atmosphere, whereas the process water is fed through a coarse separator, before it is returned to the scrubber. According to the invention a portion of the process water from the washing cycle is withdrawn and is fed through a biological purification plant (20), designed to decompose the organic contaminants, which are dissolved in the water, and after that the process water will be returned to the washing cycle.  The integration of the two cycles and the variation of the flow through the purification cycle will influence the conditioning of the washing cycle and also its washing capacity, and in this way it will be possible to maintain the remaining organic contaminants in the discharged air below a certain limit value. In order to optimize the economy of the production process as well as the cleaning process the scrubber (3) is combined with a heat exchanger (8), designed to raise the temperature of the fresh air to the drier (1) and to lower the temperature of the water to the purification plant (20).

Abstract: An endoscopic tool for dispensing units of hemostatic agent broadly comprises a hollow tube which holds a plurality of individual units of the hemostatic agent, a valve at the distal end of the hollow tube which permits the hemostatic agent to pass therethrough but prevents foreign matter from contacting the hemostatic agent while in the tube, a plunger which extends into the hollow tube and contacts a proximal unit of the hemostatic agent, and a mechanism for moving the plunger distally in incremental movements to cause, upon each incremental movement, an individual unit of the hemostatic agent to be pushed through the valve. Typically, the mechanism for moving the plunger and the proximal end of the hollow tube are held in a handle, One mechanism for moving the plunger utilizes a portion of the plunger as a ratchet by forming a plurality of conical elements thereon, and utilizes a switch in the handle which has a V-spring coupled thereto as pawl for advancing the conical elements. A second mechanism utilizes a regularly shaped notched cutout in the handle as the ratchet, and a vertical protrusion on the plunger which extends through the cutout as an engagement element. The notched cutout provides resilient stops, and the protrusion is shaped to allow it to be forced in a forward direction through each resilient stop and then to sit in another notch.

Title: Modular Jack
Inventor: OKADA MASANOBU
IPC: H01R13/514
Filed: 1993-08-06
Abstract: A modular jack applicable to a flat assembly. A hole is pierced in a flat member and a cover that can be opened and closed is disposed so as to cover an opening of the hole. When a modular plug is inserted into the hole, the cover is opened; when not, the cover is closed. When the cover is closed, it is housed in the opening, and the modular jack equals the flat member substantially in thickness. When the modular plug is inserted into the hole through the opening with the cover open, the insertion direction of the modular plug is regulated by inner walls of the hole. When the tip of the modular plug abuts against a bottom portion of the hole, the modular plug cannot be inserted any more. In the state, an electrode section located in the hole is electrically connected to electrodes of the modular plug. A hook portion disposed in the cover locks the.e modular plug so as to prevent the modular plug from easily dropping out of the modular jack even if the modular plug is pulled. If the cover is provided with a lock/release mechanism, the cover can be opened or closed through single finger motion.

Title: Pin-type light receiving device, manufacture of the pin-type light receiving device and optoelectronic integrated circuit
Inventor: YANO HIROSHI
IPC: H01L27/144
Filed: 1994-03-02
Abstract: In a optoelectronic integrated circuit, a pin-type light receiving device and an electronic circuit device are electrically connected to each other and monolithically integrated on a semiconductor substrate.      In the pin-type light receiving device, an n-type semiconductor layer, an i-type semiconductor layer, and a p-type semiconductor layer are sequentially formed on the semiconductor substrate and sequentially formed into mesa shapes. The first mesa is constituted by the p-type semiconductor layer, and the second mesa is constituted by the i-type semiconductor layer. The boundary surface between the first and second mesas is formed to match the junction surface between the p-type semiconductor layer and the i-type semiconductor layer. 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 upon application of a reverse bias voltage stays within the i-type semiconductor layer and does not reach the surfaces of the first and second mesas to be exposed. For this reason, a dark current flowing in accordance with the interface state between the side surface of the mesa and an insulating layer for protecting the surface of the mesa is reduced.      Therefore, a noise signal input in the electronic circuit device is reduced to improve the receiving sensitivity.

Title: High speed optical switching device including a capacitance structure
Inventor: RODGERS PAUL M
IPC: G02F1/01
Filed: 1993-04-13
Abstract: A high speed optical switching device (1) comprises a waveguide arrangement, incorporating a pn junction, with a large bondpad (11) for the purposes of increasing the capacitance presented by the device. Data and control signals can be input at an input port (8) of the waveguide arrangement, presence of the control signal operating to modify the optical path length of the device for the data signal. By incorporating the device in an interferometer arrangement, or by exploiting a Fabry-Perot cavity of the device, it can be used to transmit the data signal selectively, for instance so as to demultiplex a time multiplexed optical communications signal. The high capacitance provides very short recovery times so that data rates of 10 GHz and substantially above can be accomodated.
