Title: Auto-focusing device for camera
Inventor: ONUKI ICHIRO
IPC: G02B7/28
Filed: 1987-01-12
Abstract: PURPOSE:To prevent a photographing lens from generating a large shock during the driving of the lens by executing rapid driving when shock is not sensed even if a section for rapid driving is comparatively long and the rapid driving is switched to a decelerating state, and when the rapid driving is immediately turned to the decelerating state, driving the lens at a low speed. CONSTITUTION:When a point PH is newly set up on a position far from a point PL and the lens is located on a point P4 between the points PL and PH, the lens is driven at a low driving speed NL from the initial point, and when the lens is located on a point P5 exceeding the point PH, driven at a high driving speed NH. Thereby, the lens is driven for a while at the high driving speed NH when existing on the point P5, and after reaching the point PL, decelerated. Consequently, the generation of a large shock at the time of quickly switching from the accelerating state to the decelerating state can be prevented.

Guide bars and the tie bars slidably pierce through the supporting platens of mold parts, each of which contains hot runner manifold respectively at both the sides of the fixed platen and the insides of the movable surface plate and of the movable end surface plate. In addition, the fixed platen is interposed in the middle of the stroke of the tie bars so that the one of the multi-molds is closed when the other of the multi-molds is opened in response to the reciprocating motion of the ram of a cylinder. The left and the right movable surface plates and the movable end surface plate are properly connected to the guide bars. As a result, an injection nozzle can touch a closed multi-mold in order to mold by injection.

Title: External power source voltage detection circuit
Inventor: TANIMOTO JUNICHI
IPC: G01R19/165
Filed: 1993-01-14
Abstract: PURPOSE:To provide an external power source voltage detection circuit for stably operating even if a resistant division ratio is changed. CONSTITUTION:A comparator 15 outputs seventh voltage (g) for switching on a switching element 14 in a case where first voltage (a) which is lower than outside power source voltage by a specified voltage part alone produced with a constant voltage generation circuit 11 is larger than second nearly constant voltage (b). When the switching element 14 is switched on, resistance 16 divides the outside power source voltage in consideration of a specified ratio and outputs fourth voltage (d) directly proportional to the outside power source voltage. Another comparator 17 compares forward voltage (e) with the fourth voltage (d) and outputs fifth voltage (f) which indicates 'zero' when the outside power source voltage is lowered down to specified voltage and the fourth voltage (d) is lower than the voltage (e). Thereby the fourth voltage (d) is equal to the voltage (e) in an area wherein the voltage (e) is stabilized and the comparator 17 stably operates even if a division ratio of the resistance 16 is changed.
