Title: Supported pallet rack
Inventor: KONSTANT ANTHONY N
IPC: B65G1/02
Filed: 1991-01-10
Granted: 1996-03-19
Abstract: A pallet rack comprises at least one pair of spaced, parallel rails and at least one wheeled cart mounted in rolling relation with the pair of rails and defining a load-carrying area.  By this invention a cross brace extends between the rails, being positioned to support the bottom of a weak or poorly placed pallet placed on the rails adjacent the front end.  The cross brace defines a space adjacent each of the rails to permit the front end of the cart to roll to the front end of the rails between the cross brace and each rail.  The cart comprises a pair of wheel-carrying side members positioned parallel to the rails, plus transverse support members connecting the side members.  The transverse support members are spaced from the cart front end by a distance sufficient to allow the front end of the cart to roll between the cross brace and each rail.

Title: Multi-output dc-dc converter using field-effect transistor switched at high frequency
Inventor: NOCHI HIDEO
IPC: G05F1/46
Filed: 1991-01-18
Granted: 1996-03-12
Abstract: A multi-output DC-DC converter comprises a field-effect transistor connected to a one terminal of a DC voltage source, the transistor having a parasitic diode coupled in parallel relationship therewith. A resonant circuit is coupled at one end to the other terminal of the voltage source and a first diode is connected between the transistor and the other end of the resonant circuit to allow a forward current to flow therein. A second diode is connected in parallel with a series circuit formed by the transistor and the first diode to allow current to flow in a reverse direction, the second diode having a recovery time much smaller than the recovery time of the parasitic diode. A first rectifier-filter is coupled to the resonantcircuit for developing a first DC output voltage, and a second rectifier-filter is coupled across the terminals of the DC voltage source through the transistor for developing a second DC output voltage. A third diode is connected between the DC voltage source and the second rectifier-filter for blocking a current flow which would otherwise flow through the first and second diodes and the second rectifier-filter. Deviations of the first and second DC output voltages respectively from a reference voltage are detected and the gate of the transistor is driven by switching pulses having a frequency variable as a function of the deviation of the first DC output voltage and having a duration variable as a function of the deviation of the second DC output voltage.

Title: Integrated optical polarisation splitter
Inventor: DIEMEER MARTINUS B J
IPC: G02B6/126
Filed: 1991-01-28
Granted: 1995-05-30
Abstract: The invention relates to an integrated optical polarisation splitter based on the mode filter principle, in  which  the  asymmetry,  necessary  therefor,  of  the waveguides is obtained by using a polable glassy polymer as  optical  waveguide  material,  which  material  is polarisation-sensitive in the poled state and is not, or virtually not polarisation-sensitive in the unpoled state.          A Y-shaped optical waveguide pattern 8 of polable glassy polymer comprises a continuous optical waveguide formed by the optical waveguide sections 8.1 (incoming) and 8.2 (outgoing) in which the polymer is in the unpoled state and  an  outgoing  optical  waveguide  section  8.3  which connects to said optical waveguide at an acute angle and in a tapered fashion and in which the polymer is in the poled state. Since the poled material is also electro-optical, an electric field, for example generated between electrodes 2 and 10, can still correct any small deviations in the asymmetry. Advantages are simple production, with relatively high tolerances, and a short integration length of the component.

Title: Time-varying image signal coding/decoding system
Inventor: OKAJIMA MASAYUKI
IPC: H04N19/60
Filed: 1992-08-28
Granted: 1997-12-02
Abstract: In the time-varying image signal coding apparatus, a local encoded signal is quantized by a quantizing circuit, and the quantized signal is selected when refreshing is to be accomplished, and subjected to code transform by a code transform circuit to be transmitted to a time-varying image signal decoding apparatus.  The signal supplied from the quantizing circuit is a transform coefficient in the transform region, and this is divided into a plurality of groups to be refreshed on a group-by-group basis.  The transfer control on a group-by-group basis when refreshing is to take place is accomplished with a control signal supplied from a switching control circuit, and this control signal also undergoes code transform by the code transform circuit to be transmitted to the time-varying image signal decoding apparatus.  In the time-varying image signal decoding apparatus, in accordance with the switching control signal transmitted from the time-varying image signal coding apparatus, refreshing is achieved by such selection that the transform coefficient to be refreshed is directly written into a frame memory from a code inverse transform circuit.    When a time-varying image signal is to be transferred by using interframe transform and transform coding, grouping is achieved by the units of transform coefficient, and frames are rewritten with each group independent of others.
