Title: Intermittent driven transmitter
Inventor: SHIMO NORIO
IPC: H04B1/04
Filed: 1987-02-24
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE        An intermittently driven transmitter having high power output which is driven intermittently so as to transmit a signal via, for example, a satellite in which the voltage supplied to the transmitter is boosted and supplied to a capacitor.  When the signal is to be transmitted, the voltage stored on the capacitor is supplied to a constant voltage circuit which generates a constant voltage which is higher than the voltage supplied to the transmitter and which is supplied to a power amplifier in the final stage of the transmitter and, thus, the intermittent type transmitter with a suitable battery drive system is obtained.

Title: Tandem-axle walking beam suspension
Inventor: JABLE ROGER DENNIS
IPC: F16F15/08
Filed: 1987-04-28
Granted: 1990-06-05
Abstract: ABSTRACT OF THE DISCLOSURE A tandem-axle walking beam suspension is disclosed which uses bushings of novel design in the bores at opposite ends of the walking beams.

Granted: 1990-10-23
Abstract: ABSTRACT OF THE DISCLOSURE            A combined on/off and reversing switch, particularly for an electric screwdriver having a reversible motor, has a switch plate which can be rotatably mounted on an end of the motor.   Terminals of the motor extend through the switch plate and are selectively contacted by ends of two resiliently flexible contact strips carried by the switch plate.   An actuating member is moved along a selected path to rotate the switch plate to select "forward" and "reverse", and then depressed inwardly to flex an end of the appropriate contact strip to complete energization of the motor.    The  contact  strips  resiliently bias the actuating member outwardly to switch the motor "off" when the actuating member is released.   Switching the motor "on" from a neutral "off" position of the switch involves a two part movement of the actuating member.  The switch is of simple and compact construction.

Abstract: ABSTRACT OF THE INVENTION    The device has a storage vessel (2) that is connected to a compressed gas pipe (1) and whose outlet (6) discharges through a shut-off element (7) into a carrier gas pipe (10).  Shut-off element (7) and the setpoint values of a first pressure regulator (23) in compressed gas pipe (1), as well as a second pressure regulator (24) in carrier gas pipe (10), are controlled by a program control device (33) with a program memory (34), in which several programs that are selectable by a selector (37)  for charging the carrier gas stream with varying amounts of material and/or material concentrations are stored. Each program contains time-driven switching commands for opening and closing shut-off element (7) and two different setpoint values for first and second pressure regulator (23, 24). With the device, the carrier gas stream, for example, for descaling hollow billets of varying dimensions, can be charged selectively with different, precisely measured amounts of material and material concentrations (amounts of material per carrier gas volume), by which charging with different amounts of material or material concentrations can be done in quick succession.

The die member includes an annular concave die cavity which surrounds a center die post. The method includes coating at least the tubular barrel portion with a fluorocarbon coating, such as polymerized tetrafluoroethylene, prior to the installation of the fastening element to the panel. The tubular barrel portion is then driven through an opening formed in the panel generally coaxially aligned with the die member center post. The opening may be preformed or more preferably pierced by the piercing surface of the barrel portion. The coated internal surface of the tubular barrel portion is then driven against the external surface of the die post, and then against the bottom surface of the concave die cavity, forming a channel-shaped end portion which receives the edge of the panel, forming a mechanical interlock. The friction-resistant fluorocarbon coating on the barrel portion significantly improves the panel installation, including the integrity of the joint, torque resistance and sealing.
