Title: Control circuit for inverter
Inventor: NEMOTO HIROGAZU
IPC: H02M7/521
Filed: 1982-12-17
Granted: 1987-03-04
Abstract: The inverter is of a load commutation type and has arms formed of thyristors. Pulses are produced and distrubuted to the gates of the thyristors for performing, under normal circumstances, constant margin time control or constnat margin angle control by means of control circuit. The voltage across the load is detected and its magnitude is compared at with a predetermined level at. When the magnitude exceeds the predetemined level, a pulse is produced at and delivered through the distrubutor to the gates of the thyristors. As a result the direction of the load current is reversed, and the transfer of energy to the load is reduced.

Title: Regulated power supply for semiconductor chips with compensation for changes in electrical characteristics
Inventor: KEIJO AOYAMA
IPC: G05F1/46
Filed: 1986-07-30
Granted: 1990-04-16
Abstract: The semiconductor device regulates the extenal power supply voltage applied to the chip.  Variations in the electrical characteristics can be reduced by compensating the chip-to-chip fluctuations of the conductance of transistors (FETs) contained in an inner circuit positioned on the chip.  A dummy transistor having a relatively short channel length is empolyed as a circuit for detecting the electrical characteristics of the transistors formed on the chip.  The voltage drop across the dummy transistor is employed as a representative signal since it is sensitive to variations in the characteristics of the FETs contained in the inner circuit.

Date Oct. 20, 1988.In twin-chamber compressed gas packs, the collar of a diaphragm which invaginates during motion in the container is secured with its opening region in a fold or in the upper part of the container, in order to provide the required sealing between product chamber and working fluid chamber. The disadvantage of packs of this type is that the use of multi-part containers is mandatory and/or that a support ring incorporated in the diaphragm produces a frictional force which may be large enough to prevent ejection of the feed material because of an insufficient pressure differential between the chambers. These drawbacks are overcome by securing the entire region of the collar to the internal wall of the casing.
