Abstract: PURPOSE: A forming apparatus and a method of a perforated product are provided to form the perforated product consecutively and automatically by using a movable die and a sliding die without an air-blowing portion and to produce thick or thin products sealed completely. CONSTITUTION: A forming apparatus comprises a sliding die(22); a fixed base(24); an actuator(27); a fixed die(15a) and a movable support body. The sliding die has a cavity(4a) corresponding to a middle portion of a perforated product on one side. A protrusion portion(20) is formed to the other side of the sliding die. Melting resin is injected to the sliding die by an intruder(21). The fixed base supports a rear portion of the sliding die. A sprue(23) is formed to the fixed die to flow melting resin. The actuator is arranged across a horizontal arm(26) of a holder(25). The holder is fixed to an upper portion of the fixed base. The actuator moves the sliding die up and down by control of a control unit. The fixed die is opposite to the sliding die and has a protrusion portion(20a) to correspond to the cavity on one side. A cavity(4b) is formed to the other side of the fixed die to form the other middle portion. The movable support body is fixed to a rear surface of the fixed die. The movable support body is reciprocated right and left by the other actuator controlled by the control unit.

Abstract: The volume of a loudspeaker in a telephone is automatically adjusted according to the ambient noise at the telephone location. During a predetermined time window which exists during the initial period of a telephone call, the ambient noise is measured, and the volume of the loudspeaker adjusted accordingly. For example, the time period may exist between the time when the telephone goes off-hook, until the time when the handset is placed near the ear. Adjusting the ambient noise during this period has the advantage of not having to filter out the user's speech, as would be the case when measuring the ambient noise while the user is speaking. Furthermore, there is no requirement for circuitry which detects gaps in speech.

Title: Detection of base contaminants in gas samples
IPC: G01N1/00
Filed: 2000-01-14
Abstract: A detection system for detecting contaminant gases includes a converter, a detector, a primary channel for delivering a target gas sample through the converter to the detector, and at least two scrubbing channels for delivering a reference gas sample through the converter to the detector. Each of the scrubbing channels includes a scrubber for removing basic nitrogen compounds from the reference gas sample, while the primary channel preferably transmits the target gas sample without scrubbing. The converter converts gaseous nitrogen compounds in the target gas sample to an indicator gas, such as nitric oxide (NO), and a control system directs the flow of a gas sample among the primary channel and the scrubbing channels. In accordance with one aspect of the invention, the basic-nitrogen-compound concentration can be measured by comparing the concentration of the indicator gas detected in the reference sample with the detected indicator-gas concentration in the target sample. The use of multiple scrubbing channels enables the detection to operate continuously since each scrubber can be alternately purged while another is scrubbing.
