Title: Radio pager receiver capable of readily checking whether or not memory backup is correct
Inventor: IDE MOTOKI
IPC: H04W84/02
Filed: 1988-02-26
Granted: 1992-06-30
Abstract: Abstract of the Disclosure:     In a radio pager receiver comprising a memory (14) which is activated by main electric power and backed up by backup electric power, and which has a message area and an additional area for memorizing messages and administration data for administration of the messages, respectively, a message processor (20) is included in the receiver to judge whether or not the administration data are correctly kept in the additional area when the memory and the message processor are activated after the message processor is once deactivated.  The message processor thereby produces a result signal representative of judgement.  The message processor may process the message signals to have the administration data related to one another in accordance with a logical relationship.  In this event, the message processor judges whether or not the logical relationship is correctly kept in the additional area.  The logical relationship is checked by message linkage information indicative of a message order or processing the message signals.  The logical relationship may also be checked by another linkage information related to a length of each message.  The message processor may erase the message  and the administration data from the message area and the additional area when the result of (Abstract of the Disclosure continued) judgement indicates that the administration data are not correctly kept in the additional area.

Title: Symmetric optical device
Inventor: HINTON HARVARD S
IPC: G02F3/00
Filed: 1988-03-28
Granted: 1992-03-31
Abstract: SYMMETRIC OPTICAL DEVICE     Abstract An optically bistable device 100 is disclosed having first and second semiconductor multiple quantum well regions 101 and 102 with complementary high and low absorption levels for emitting first and second output light beams 162 and 163 having complementary low and high power levels. The optical device comprises first and second photodetectors 103 and 104 having respective quantum well regions 101 and 102. The photodetectors are responsive to first and second light beams 160 and 161 for electrically controlling the optical absorption of each of the two quantum well regions. The state of the device is determined by the transmission level of light beam 161 passing through multiple quantum well region 102 and being emitted as output light beam 162, whereas the complementary state of the device is determined by the transmission level of complementary output light beam 162. A variable optical attenuator 701 concomitantly and proportionally varies the power level of input light beams 160and 161 to maintain the state of the device over a wide range of input powers. When operated in the bistable operating region of the device, either one of control light beams 180 and 181 with a low power level changes the device from one state to the other. Two threshold values of the ratio of the power of the light incident on the two photodetectors establishes where the device switches from one state to the other.

Abstract: LOG STRUCTURES AND METHOD OF CONSTRUCTING SAME                  ABSTRACT OF THE DISCLOSURE This invention relates to a unique log structure system and method of constructing same.  An array of ripples is machined into parallel top and bottom surfaces of each log.          The ripples are the same size, spacing and configuration and comprise peaks and valleys in the top ripple surface aligned with valleys and peaks, respectively, in the lower ripple surface.  Logs are stacked with the top ripple surface of a lower log interlocked with a bottom ripple surface of an upper log.  At the corners first and second logs are notched so as to interlock with their axes intersecting at a predetermined angle. Third and fourth logs are notched and interlocked at the structure corner with their axes also intersecting at the predetermined angle.  The third and fourth logs are stacked on top of the first and second logs so their respective ripple surfaces interlock.  Some logs are interlocked between other logs but with a narrower horizontal dimension so as to permit spaces between logs for wiring.  Holes filled with sealant and additional notches aligning with the holes are formed in the logs perpendicular to the ripple surfaces where the logs are notched to prevent air passage through the notches.  Additional ripple surfaces are provided on vertical surfaces of logs to facilitate butt and corner joining, particularly in logs of man-made materials.        The method includes the steps of forming upper and lower ripple surfaces in logs, stacking the logs, notching the logs, interlocking the notches, interlocking the ripple surfaces, forming holes through the logs at the interlocked notches, and filling the holes with sealant to prevent air flow through the notches.

Abstract: ABSTRACT OF THE DISCLOSURE            Hand-held ski sharpeners are well known, but they are difficult to use and tend to produce unsatisfactory results.  Electrically operated ski sharpeners are also known in which a rotating grinding wheel is used to apply a cutting pressure to the edge of the ski.  This cutting pressure may be adjustable.  However, in such sharpeners, the grinding wheel can easily become damaged and worn and therefore needs to be dressed before use.  The ski sharpener disclosed herein comprises an abrasive disc (30) which is rotated by a motor (20), the disc being biased to a position where it is proud of a guide surface (9) by means of which the sharpener is guided along the ski.  The biasing of the disc (30) is adjustable by means of a set screw (23) and lock nut (24) attached to an axially movable motor spindle (28) against the action of a compression spring (27) or other means applying the desired force.  This enables different cutting pressures to be applied and hence different amounts of material to be removed.  The disc (30) has an abrasive surface (32) which is pulled on to the edge of the ski as the sharpener is moved along it.
