Title: Reinforced wood beam
Inventor: COUTURE RAYMOND
IPC: E04C3/02
Filed: 1990-02-05
Abstract: ABSTRACT OF THE DISCLOSURE A wood beam provided with reinforcement to increase the tensional strength, in particular in its bottom portion to thus allow its use for relatively longer free spans and/or heavier floor or roof loads. This wood beam is economically made of wafer boards, reinforcing filaments in a channel along the bottom longitudinal edge of the beam, and adhesive bonding the filaments in the channel and to the associated wood boards. Crosscut incisions are provided along the longitudinal joint to increase the surface of adherence for the adhesive. This beam is especially used as a floor joist along with an L-shaped header joist and a reverse T center beam also made of wafer board. A complete floor system is thus provided.

Title: Magnetic head and process for producing same
Inventor: YOSHIKAWA HIDEKI
IPC: G11B5/105
Filed: 1990-02-07
Abstract: ABSTRACT OF THE DISCLOSURE         A magnetic head having a pair of core half segments opposed to each other face to-face, with a magnetic  gap formed therebetween, and bonded to each other with a joint layer.  The joint layer is formed by a nonmagnetic oxide layer having a high melting point and extending over the joint faces of the segments.  A portion of the nonmagnetic oxide layer functions as the magnetic  gap.  The nonmagnetic oxide layer is formed by causing a solution of organic metal compound to penetrate into a space between a pair of core half members providing the pair of core half segments and heating the solution to change the solution to a sol and then to a gel and eventually solidify the solution.

Abstract: A cleaning method and cleaning system using an organic solvent such as Freon.   A cleaning tank (1) is closed  after  an article  (2)  to  be cleaned  is  placed within the cleaning tank.   The cleaning tank (1) has a downwardly concave bottom wall  (60)  carrying ultrasonic oscillators  (11).    The  solvent  is  supplied  to  the cleaning tank (1) from a solvent storage tank (3).   The article is cleaned with the supplied solvent.  After the cleaning, the solvent is discharged in liquid state from the cleaning tank (1) while vapor of the solvent which remains in the cleaning tank is discharged to a condenser (16)  to condense the vapor.   The condensed solvent is returned from the condenser (16) into the solvent storage tank (3).  After the liquid solvent and vapor solvent are discharged  from  the  cleaning  tank  (1),  the  cleaned article is taken out from the cleaning tank.  Before the cleaned article is taken out, air is introduced into the cleaning tank (1) at least at a last part of the step of discharging the vapor of the solvent.  The condenser (16) is incorporated in a distiller  (14).   A solvent vapor supplying unit  (34)  is connected to the cleaning tank (1).  The thus provided closed system prevents release of Freon to the atmosphere.

Filed: 1990-08-08
Abstract: An infant environmental transition system and method provides an infant with a controlled, healthy transition from an intrauterine environment to the extrauterine environment, and includes a housing within which the infant is supported by a soft, form-fitting bed. Environmental conditions provided within the housing include simulated motions, sounds and tactile sensations resembling the intrauterine environment. A suspension and drive system controls the degree of movement imparted to the housing and to an infant supported therein.    The resulting motion closely approximates the motion experienced by the fetus while the mother is walking. The sound profile simulates intrauterine cardiovascular and gastrointestinal sounds. The system simulates day and night variations in motions and sounds, integrates changes to the environment over time toward the natural extrauterine environment, and may respond to infant activity or other imputs at various intervals.

Patent CA-2031580-A1 (CA)
IPC: H03G1/00
Filed: 1990-12-05
Abstract: A General Purpose Low Cost Digital Amplitude Regulator Abstract Apparatus for digital amplitude regulation is disclosed, for use as a volume control or the like, utilizing pulse width modulation to control gain through the variation of the incremental resistance of a two terminal non-linear element, the resistance of which varies with current, e.g., a diode or diode like element. A stream of pulses, the duty cycle of which is variable and digitally controlled, is filtered to produce a quasi-continuously variable direct-current (DC) voltage. The DC voltage either directly or by providing a DC current regulates the gain of an amplifier that is amplifying the signal of interest by regulating the transmission characteristics of the diode. For low cost implementation in a system already employing a microprocessor or microcomputer the determinative duty cycle can be derived under software control and supplied as an output from a single latchable output pin. In an exemplary implementation, the incremental resistance of an ordinary silicon diode operated in accordance with the small signal model of a diode. Additionally, the use of an energy storing type filter allows the the continuous stream of variable duty cycle pulses to be momentarily interrupted so that a pin used for supplying the pulses can be used for the performance of additional functions without affecting the perceived volume level.

Abstract: Disclosed is a communication apparatus for an input speech signal which calculates linear predictive coefficients of the input speech signal and inversely filters the speech signal by using the linear predictive coefficients in order to flatten the spectral envelope of the input speech signal and produce a predictive residual signal.  A low power frequency component is adaptively removed out of frequency components of the predictive residual signal by using the calculated linear predictive coefficients.  The linear predictive coefficients are converted into a signal having the removed frequency components.   The converted signal and the removed predictive residual signal are combined.  This configuration of the present invention make it possible to faithfully transmit an important speech component including the Formant component without having to increase a data amount of transmitted information, and thereby to provide a communication apparatus for a speech signal which ensures high sound quality.

Abstract: Abstract of the Disclosure A heat shield retainer and method is provided for mounting a heat shield onto a polymeric fuel tank.  The heat shield retainer comprises a nut and bolt combination and a retainer body.  The retainer body has bulbous pegs located on a first side thereof for engaging within corresponding sockets located within a fuel tank to secure the retainer body to the fuel tank.  The retainer body further includes a releasable channel located on a second side thereof for releasably connecting the nut and bolt thereto.  One or more retainers of the present invention may be employed to mount a heat shield onto a polymeric fuel tank.  After a polymeric tank has been formed, and before it has cooled, the respective pegs of each heat shield retainer are inserted into corresponding sockets located within the fuel tank.  As the tank cools, the polymeric material of the tank defining the sockets contracts about the pegs.  As a result, after the tank cools, the pegs are locked within the sockets, and hence to the fuel tank.
