IPC: B63H25/00
Filed: 1981-08-28
Abstract: A plastic material, preferably polyvinylidene fluoride 
(PVDF) film, made highly piezoelectric by known methods, is 
placed in a sensor unit structure wherein pressure is exerted 
against the piezoelectric film by means of rotation of the 
steering wheel of the boat or vehicle to thereby cause the 
piezoelectric film to generate electric signals which are used 
in controlling the rpm of a low-inertia, instantaneously 
reversible steering power assist motor. The rpm of the motor 
is substantially proportional to the electric signals, which, in 
turn, are determined by, and responsive to, the degrees of 
rotation and speed of rotation of the steering wheel. The 
direction of rotation of the steering wheel determines the 
direction of steering assist, i.e., to the left or right. Available 
torque of the motor however is substantially inversely 
proportional to rpm of the engine propelling the boat or 
vehicle.

preform (14) comprising a segment of fiber glass web coated 
with a thermosetting and thermally conductive plastic is 
positioned on each chip pad between the chip pad and the 
active face of the I.C. chip. The plastic material of the preform 
encapsulates the active face of the chip, including a portion 
of each of the leads proximate the chip and secures the chip 
to the chip pad. The outer lead bonding sites of the leads are 
bonded to OL pads of the substrate with exposed portions of 
the leads between the OL pads and the encapsulated 
portions being bent away from the substrate and under 
compression. A heat sink (42) is bonded to the heat sink pad. 
The plastic material of the preform, the chip pad and the 
thermally conductive material filling the thermal passage 
provide a low impedance thermal path between the I.C. chip 
and the heat sink.

Abstract: The present invention is an electronic piano that 
includes various «easy play» features that enable a person 
with little musical training to play the piano producing 
music similar to that of a skilled musician. The «easy play» 
feature automatically creates musical and rhythmic piano 
accompaniment patterns in response to playing either one 
key (One Finger Chord mode) or a chord (Funchords mode) 
with the heft hand. The player plays the melody of the 
desired tune with the right hand. Instead of having to move 
the fingers of the left hand to play complex piano accom­
paniment patterns, as with a conventional piano, the player 
only needs to play a note or chord, and move the finger or 
fingers of the left hand to a different playing key and keys to 
change chords and patterns. In the standard piano mode, 
this instrument resembles an acoustic piano in function. 
The invention also includes a set of pushbutton switches 
which control the «easy play» features of the instrument. 
The features in the invention include: Funchords, One 
Finger Chord, Dynamic Pro Harmony, Harmony Dynamic 
Adjustment Minor Touch Strip, Arpeggio Tough Strip Style 
Selector, Style Expanders, Coupler, Manual Advance, Stac­
cato, and Memory.

Filed: 1982-12-08
Abstract: A process for applying a patterned coating to a circuit board 
(31) without the use of a patterning mask. A surface (30) of the 
circuit board is coated with uncured material (32) having a cure 
reaction which is inhibited by the presence of oxygen. The thickness 
of the material on land areas (34) surrounding holes (36) through 
the circuit board is reduced by causing a portion of the material to 
flow into the holes. The material is then exposed, in the presence 
of oxygen, to an energy source which advances the cure reaction only 
of sublayers (37) of the material which are isolated from the oxygen 
by overlayers (38) of the material. Surface layers of the material, 
including substantially the entire thickness of the reduced 
thickness portions of the layer, remain uncured, allowing subsequent 
selective removal of the uncured portions of the material.
