Inventor: SHIMIZU KEIICHI
IPC: F04B27/08
Filed: 1992-05-22
Abstract: A wobble plate type compressor having a cantilevered drive mechanism is disclosed. The compressor includes a compressor housing having a plurality of cylinders and a crank chamber adjacent the cylinders.  A reciprocative piston is slidably fitted within each of the cylinders.  A drive mechanism is coupled to the pistons to reciprocate the pistons within the cylinders.  The drive mechanism includes a drive shaft which extends through an opening of a front end plate and extends  into the compressor housing. A cam rotor is attached to an inner end of the drive shaft and rotates therewith.  A support mechanism radially and rotatably supports the drive mechanism.  This support mechanism,  which is formed within the cam rotor and interfits with the front end plate, includes  a bearing located within the cam rotor. Accordingly, the above construction reduces the moment of force acting on the drive mechanism at its radial support center by moving the radial support center closer in the axial direction to the point on the cam rotor at which the maximum gas compression force acts. As a result, the life of the bearing, and the compressor itself, is increased and undesirable vibration of the drive mechanism during operation of the compressor is reduced.

Filed: 1992-05-08
Abstract: An optical communication system wherein a wavelength used by a terminal for transmission and reception is assigned thereto in accordance with a call request from the terminal.           When the terminal makes a call request at a control wavelength, a wavelength control unit selects a wavelength to be used by the calling terminal out of the wavelengths unused on a wavelength-multiplex communication path, and informs the terminal of the selected wavelength at the control wavelength.  The terminal adjusts the wavelength of transmitting and receiving circuits to the informed wavelength.           As an example of the optical communication system is disclosed a wavelength-sharing optical exchange system.    A connection request from a terminal is transmitted through a wavelength-multiplex communication path at a control wavelength.  The wavelength is directed through a subscriber line control unit to a network channel control unit.  The network channel control unit retrieves a wavelength table contained therein to decide if the terminal at the other end is available.  If the called terminal is available, the network channel control unit selects a usable wavelength out of the wavelengths recorded on wavelength table and sets a switchboard such that the switchboard can operate at the selected wavelength.  Further, the network channel control unit informs the calling and called terminals of the selected wavelength at the control wavelength via the subscriber-line control units.  Both of the terminals then set transmitting and receiving wavelengths to the selected wavelength.

Patent CA-2070361-A1 (CA)
Inventor: ORGOVAN ANDREW J
IPC: H02P23/00
Filed: 1992-06-03
Abstract: The invention is carried out by providing an adjustable frequency power supply connected to an alternating current induction motor which is rotated at speeds in excess of 60 hertz.  A plurality of sequential frequency ranges are selected which, together, comprise a total frequency range from a maximum frequency range in excess of 60 hertz to 60 hertz which is applied to the motor.  For each frequency range, a maximum breakdown torque of the motor is determined.       When it is desired to decrease the speed of the motor, it is decelerated sequentially through each frequency range at a different deceleration rate for each range such that the maximum breakdown torque of the motor within each frequency range is not exceeded.  Each different deceleration rate for each frequency range is determined by selecting the minimum period of time, for each frequency range, during which the motor may be decelerated without exceeding the maximum breakdown torque of the motor within that frequency range.          Also, the deceleration rate for each frequency range may be selected by determining the deceleration rate of the motor at the highest frequency in each range which will not result in exceeding of the maximum breakdown torque of the motor.  The motor is then decelerated within each range at the deceleration rate of the highest frequency in the range.

Abstract: The known 4-cycle internal combustion engine including a crankcase, a cylinder, a cylinder head, a piston adapted to reciprocate within the cylinder, a combustion chamber formed by the piston, the cylinder and the cylinder head, and a crankshaft connected to the piston via a connecting rod, is improved in order to enhance a thermal efficiency, to lower an exhaust level of fuel and to make it possible to arbitrarily select-an operation attitude of a 4-cycle engine.  The improved 4-cycle engine comprises an intake passage and an exhaust passage provided in the cylinder head, a rotary valve rotating synchronously with the crankshaft at a speed one-half of that of the latter for communicating the intake passage and the exhaust passage with the cylinder respectively at the time of an intake stroke and at the time of an exhaust stroke, a check valve communicating the intake passage with a crankcase chamber to allow only a flow directed towards the intake passage, and fuel feed means for feeding mixture gas of air, fuel and lubricant oil into the crankcase chamber.          Thereby, suction of the mixture gas into the crankcase chamber as well as feed of the mixture gas into within the crankcase chamber to the intake passage are made possible by variation of the pressure within the crankcase chamber caused by reciprocating motion of the piston.

Title: Method and reagent for determining specific nucleotide variations
Inventor: SOEDERLUND HANS
IPC: C12Q1/68
Filed: 1991-02-15
Abstract: Detection of variable nucleotide(s) is based on primer extension and incorporation of detectable nucleoside triphosphates. By selecting the detection step primers from the region immediately adjacent to the variable nucleotide, this variation can be de-tected after incorporation of as few as one nucleoside triphosphate. Labelled nucleoside triphosphates matching the variable nu-cleotide are added and the incorporation of a label into the detection step primer is measured. The selection of the detection step primer is important to the method according to this invention and is dependent on the nucleotide sequence of interest. The detec-tion step primers are preferably selected so to span the region immediately toward the 3' end from the variable nucleotide to be detected. The method is useful in identifying specific point mutations and genetic variations.
