Title: Ejector pump
Inventor: ISE YOUJI
IPC: F04F5/46
Filed: 1984-02-21
Abstract: PURPOSE:To reduce the size of ejector pump by mounting a solenoid valve on the hole section of pump body and opening/closing the inlet of nozzle hole by means of the tip section of movable chip. CONSTITUTION:Upon power supply to a solenoid 7b under operation of ejector pump, a plunger 7e is attracted to the center post 7c to move a movable chip A to the left against a spring 32 and the valve body 10 will open the nozzle hole 3a. Consequently, compressed air will pass through the gap 9 and ejected from the nozzle hole 3a to the ejector hole 2a thus to suck the air in sucker B from the suction chamber 4 to the ejector hole 2a while to discharge through a muffler 33. Consequently, the interior of sucker B is depressurized to suck a part C and carry to the desired place. Upon interruption of power to the solenoid 7b, the movable chip will close the nozzle hole through the valve body 10 to pressure feed the compressed air through a closing valve 16 to the suction port 6 thus to release the negative pressure in the sucker quickly.

Title: Exposure control circuit for video camera
Inventor: KONDOU NORIAKI
IPC: H04N5/235
Filed: 1991-01-31
Abstract: PURPOSE:To simplify adjustment by preventing high precision from being requested in the arrangement position of a color bar at the time of adjusting an image pickup signal level by means of displaying the prescribed picture of the color bar with a video camera which respectively detects the image pickup signal levels from plural exposure detection areas and controls exposure. CONSTITUTION:When a mode setting signal is supplied from a terminal 17 and a system is set to an adjustment mode, weighting coefficients K1 and K2 from a coefficient generation circuit 16 are equally set, for example. Thus, exposure is controlled in correspondence with the image pickup levels of the whole screen. Thus, even the video camera detecting the image pickup signal levels from plural exposure detection areas can easily adjust the image pickup signal level by displaying the prescribed picture of the color bar without high precision being requested in the arrangement position of the color bar.

IPC: G11B21/20
Filed: 1983-03-01
Abstract: PURPOSE:To reduce output modulation and to prolong the life of a floppy disk by setting the abutting position of a pivot backward from the center of a magnetic head. CONSTITUTION:The position of a support pin 21 is set backward from the center point of the magnetic head 20 and a contact force point is set at the intersection O of the center line of the magnetic head 20 and the contacting surface of a medium. When the support pin 21 is shift backward from the center of the magnetic head 20, distance (l) is l=Htantheta, tantheta=F/W, and F=Hmu, so l=Hmu. Namely, when the position where the support pin 21 presses the magnetic head 20 is shifted backward from the center of the magnetic head by muH, the magnetic head surface applies uniform surface pressure to the medium; the life of the medium is prolonged and the output modulation is reduced, thereby reducing errors in recording and reproduction. In said equations, theta is the angle of composite force N, H is the height of the magnetic head from the contact surface of the medium to the lower end of the support pin, and mu is the coefficient dynamical friction between the magnetic head and medium.
