Title: Injection mold of plastic lens
Inventor: OSEKO HISAAKI
IPC: B29C33/42
Filed: 1991-03-20
Abstract: PURPOSE:To prevent flash from developing even under the condition that a retainer and an insert consisting of a mold deform. CONSTITUTION:Under the condition that the end part 34a on the cavity 30 side of a movable side mounting member 34 is extended to the center side (to the center axis line X side of the surfaces of a lens to be produced) of a cavity 30, the contact surface 35 between a movable side insert 31 and the end part 34a of the movable side mounting member 34 and the contact surface 37 between the end part 34a of the movable side mounting member 34 and a fixed side member 3b are set normal to the mold opening direction (to the direction along the center axis line X of the lens surfaces). Since strong mold clamping pressure is applied to the contact surfaces 35 and 31, even when high temperature, molten and highly fluid resin is filled in the cavity 30 under high pressure, no clearance develops. Even when the movable side mounting member 34 slightly deforms elastically normal to the mold opening direction, no flash develops.

Title: Film winding and rewinding device
Inventor: SHIMADA TAKAHISA
IPC: G03B17/00
Filed: 1988-04-04
Abstract: PURPOSE:To automate film winding and rewinding operation by adopting such a constitution that the normal rotation of one motor winds up film and its reverse rotation rewinds the film when its last frame is detected. CONSTITUTION:A microcomputer 40 switches the normal or reverse rotation of the motor 1. Its normal rotation winds up the film. When the last frame of the film is judged to appear during winding up the film because of its fully stretching, the motor is reversely rotated to automatically rewind the film. The last frame is decided as follows: 1st and 2nd switches SW1 and SW2 detect plural cams when the film is fully stretched, that is, the condition of a one- rotation cam 10 and that of a winding stop member 22, respectively, and the microcomputer 40 decides the last frame. With respect to a winding action, the motor 1 winds up the film from a sprocket 17 to a spool 9. Thus, the winding and rewinding actions can be automated.

Title: Method of interrupting transition
Inventor: BURAIAN JIYONSON
IPC: H04N5/268
Filed: 1989-04-03
Abstract: PURPOSE: To smoothly change a transition on a video switcher by an operator, without applying any visual abnormality to a viewer by arranging the next new video signal source on a preset bus and turning a current video signal source on a program bus into black as planned. CONSTITUTION: An event is supplied automatically or from an event programming system, and a button for skipping to the present of the video signal source or to the next event is activated, so that fade to black is completed when starting the transition period of the current signal source and after the activation period of any suitable video signal source, it can be made into the newly selected video signal source. On the other hand, the signal of the program bus (the signal path of the current program) is kept in black until the new video signal source can be watched, as needed. Therefore, the transition is interrupted, and the video signal source is smoothly changed into other one only, while applying a short black term to the viewer in case of the worst.  Thus, the operator can smoothly change the transition on the video switcher, without applying any visual abnormality to the viewer.

Abstract: PURPOSE:To prevent engine stall previously and maintan the superior operation performance by copensating the adjustment of an idle revolution speed by the car-speed adjusting means of a constant speed controller, even in the case when an idle control system is in trouble. CONSTITUTION:A car-speed adjusting means 63 controls a throttle valve 8 so that a constant-speed traveling value set by a constant-speed traveling value setting means 62 is obtained. When an idle operation state detecting means 60 detects idle operation state, the opening and closing of the throttle valve 8 is controlled by the control signal supplied from an idle revolution speed adjusting means 61. When a trouble detecting means 64 detects the trouble in at least one of the both means 60 and 61, the idle revolution speed is adjusted by the car- speed adjusting means 63 through a compensating means 65. Therefore, when an idle revolution speed control system is in trouble, the idle revolution speed can be adjuted by an existing constant-speed controlling apparatus.
