Title: Electrochromic display devices in electronic timepieces
IPC: G02F1/15
Filed: 1981-01-12
Granted: 1984-04-18
Abstract: An electronic timepiece provided with an electrochromic display device as a time related information display. The ECD is driven by an electric charge transfer method. The electric charges which cause coloration of segments directly transfer from non-selected segments to selected segments. In the ECD additional concealed dummy segments temporally store the excess electric charges when the total area of the selected segments decreases, and release the stored electric charges when the total area of the selected segments increases, so that the electric charge density of colorized segment is always kept constant. Moreover electric charges are periodically supplied to the display device so as to compensate the lost amount which was dissipated during transfer cycle.

Title: Self-priming pump
Inventor: HIRAKAWA NORISHIGE
IPC: F04D13/02
Filed: 1986-07-09
Granted: 1988-12-21
Abstract: A communication hole is bored through a partition member which divides an intake-side priming fluid chamber from a discharge-side priming fluid chamber, whereby the two chambers are connected. The communication hole serves to prevent, on a predetermined level, a backflow of a pump fluid due to siphonage caused on the intake side when pumping operation is stopped, thereby securing a priming fluid in a pump casing. A valve assembly including a valve member is disposed corresponding to the communication hole. The valve member, which is always urged to an open position, is moved to and held in a position where it is caused to close the communication hole by the action of the pump fluid flowing in a feeding direction during pumping operation. When the pump is stopped to cause the backflow of the fluid, the valve member is moved back to the open position by the urging action.
Patent GB-2207552-B (GB)
Title: Thyristors
Inventor: CREES DAVID EDWARD
IPC: H01L29/74
Filed: 1988-07-21
Granted: 1990-10-03
Abstract: A thyristor having a main cathode 1 and an anode electrode 2 between which conduction occurs, also includes a region of long charge carrier lifetime 12. During forward conduction between the cathode 1 and anode 2, carriers diffuse into the region of long lifetime region 12. If, during reverse recovery, but prior to the thyristor recovery time, a positive going voltage ramp is applied across the device, turn-on is initiated in the long lifetime region 12 due to the presence of unrecombined charge and displacement currents generated. The current produced is limited by resistors 9 and 17 to prevent damaging high levels and is used to switch on the remainder of the thyristor (via an amplifying gate) without any damage to the device occurring. In previous thyristors not including a region of long carrier lifetime, such a voltage might result in turn-on occurring over only a very small volume and the heat dissipated could destroy the thyristor.
