Abstract: The sensor for improving resolution comprises  odd  and  even rows of photodetectors (PD) coupled by transfer gates (TG)  to  an array  of VCCD  regions  (VCCD)   operable   as   scanners.   The photodetectors  (PD)  in  each  row  are  operatively   associated alternately with the left and the right sides  of  the  respective VCCD regions across the array, and the photodetectors (PD) in each pair  of  adjacent  photodetectors  not  having  a   VCCD   region therebetween are spaced apart by a channel  stop  region  (ST).  A four phase clock signal consisting  of  four  fields  is  used  to operate the sensor. The sensor provides an increased area ratio of photodetectors to the VCCD regions.

Title: Vacuum pump control device for fire engine
Inventor: BANG CHOL-SHIK
IPC: A62C3/07
Filed: 1990-06-26
Granted: 1992-07-24
Abstract: The control device has means  for  controlling  the  magnetic valve (9), and comprises a pneumatic cylinder (8) operated by  the magnetic valve (9) for switching the pneumatic,  a  roller  clutch (2) of vacuum pump (1) connected with the piston (7) of  pneumatic cylinder (8).  The  control  means  of  magnetic  valve  includes pressure detecting switch for  supplying  the  power  to  magnetic valve and indicating  lamp  of  vacuum  pump,  emergent  selecting switch for applying power to  magnetic  valve  (9).  The  emergent selecting switch (SE), cut-off switch  (SP)  and  pressure  switch (PS) shuts power of magnetic valve (9) mounted  at  inlet  of  the cylinder.

Title: Sirocco fan
Inventor: PARK IN-CHOL
IPC: F04D29/30
Filed: 1990-07-30
Granted: 1992-10-12
Abstract: The sirocco fan is a centrifugal fan for high effenciency and low- noise type. In the sirocco fan,  a  single  blade  (2)  is  to satisfy  the  equation  of  y  =δ (l-x)/3  [1-(l-x)2/l2   [y = deflection direction coordinate of a single blade (2); δ =  angle of flow changing direction; l = length of a single blade (2); x  = length direction coordinate of a single blade (2) . The  angle  of flow changing direction is 90-93 degree.
