Filed: 1981-01-12
Granted: 1984-12-07
Abstract: The camera comprisea a solid state image sensing device from which dot sequential color signals are derived. A gain control signal generator produces a gain control signal level set at a predetermined signal level which is sequentially changed to change the output level of the image sensing device. A dot sequential gain control amplifier is controlled by the gain control signal. A color signal separator receives the output of the amplifier and converts the gain controlled dot sequential color signals into simultaneous color signals.

Title: Wrap-around packaging machine
Inventor: CONFORTO PETER M
IPC: B65B5/02
Filed: 1987-09-08
Granted: 1992-05-22
Abstract: A blank for forming a wrap-around carton is delivered to a moving support carriage which is moved to a station where the moving carriage receives a predetermined number of articles to be packaged. The carriage, with the articles resting on the bottom portion of the blank, is moved downstream while cams actuate tucker fingers which pivot up to fold the tuck flaps of the blank toward each other, causing the end and side panels to be elevated. Another cam actuates a pusher bar which pivots up to push the articles. The carton blank and the articles are thus positively moved through subsequent flap folding and gluing stations, avoiding the problems which can arise due to the use of separate means for moving the articles and the carton blank. A cam operated hinged plate is used to segregate the leading articles at the entry to the machine.

Title: Cache memory
Inventor: KIM SONG-UN
IPC: G06F12/08
Filed: 1990-12-26
Granted: 1992-12-26
Abstract: The circuit optimally shares one cache memory to improve  the efficiency  of  the  cache  memory  when  a  snooper  and  a   CPU simultaneously use the memory. The circuit  includes  an  approach controller of processor (11) for interfacing the  data  needed  to approach a CPU cache (4) or a CPU (1), an approach  controller  of snooper  (12),  a  memory  controller  of  cache  data  (13)   for controlling the data state of a cache memory (6) according to  the control signals from the two approach controllers (11,12),  and  a cache controller (3) composed of the 1st cue (Fc;14) and  the  2nd cue (Fs;15).
