Title: Apparatus for preventing collision between hoists
Inventor: ONOSE AKIO
IPC: B66C15/04
Filed: 1977-12-07
Abstract: PURPOSE: To prevent collision between hoists by means of impedances connected between trolley wire and detectors provided in each hoist.  
     CONSTITUTION: Trolley wire 2 divided into a plurality of sections is extended in parallel along power source wire, and an electric impedance is provided at each of the junctions between adjacent two sections of trolley wire 2, such that it can be detected from the impedance connection that hoists H 1 , H 2  are present at adjacent two sections of trolley wire 2. However, output stignal is lowered between two sections spaced from each other by the presence of one further section of trolley wire 2, since there exist two impedances between them, so that presence of hoists H 1 , H 2  in these spaced-apart sections can not be detected. Therefore, a rearward or succeeding hoist is permitted to pass through the section freely. With such an arrangement, it is enabled to operate a plurality of hoists safely without causing collision

Filed: 1982-08-25
Abstract: PURPOSE:To obtain quickly a characteristic point in response to the shape of stroke with a simple circuit constitution, by taking the sampling point respresenting the characteristic of the shape such as start, end and bending point of the stroke as a characteristic point. CONSTITUTION:Inputted manually written character information is stored in a sampling point memory section 1 as sampling point number and coordinates. The sampling point stored in the memory section 1 is stored in a characteristic point memory section 5 as a characteristic point at the same time in terms of sampling point number and coordinates. Then, the memory section 5 applies the coordinates of the characteristic point to a distance operating section 2 and the sampling point number and coordinates of the sampling point to the distance operating section 2 and a maximum value selecting section 3. The operating section 2 calculates the distance between the straight line and the sampling point between the characteristic point. The selecting section 3 selects the maximum value among distances transmitted sequentially and stores it. This maximum value is applied to a comparison section 4 and compared with a preset value thetath. When the maximum value is the thetath or over, the sampling point selected at the selecting section 3 is discriminated as the characteristic point and the sampling point number and coordinates are stored in the memory section 5.

Title: Drum scanning type ink jet recorder
Inventor: HIRATA TOSHITAKA
IPC: B41J25/308
Filed: 1979-11-12
Abstract: PURPOSE:To reduce the bending of the flow of ink particles by a method wherein a space between the surface of a drum and a rectifier plate is narrowed by driving the rectifier plate to move backward while synchronizing the movement with that of the plate for holding down recording paper. CONSTITUTION:If a drum 1 is turned clockwise, a plate 1b used to hold down recording paper reaches the end portion of a rectifier plate 5. While the plate is clearing the end portion, a supporting frame 6 is forced to move backward in resisting the repulsing force of springs 101, 102. When the plate 1b has passed through  the end portion, the frame is pushed forward by the repulsing force of the spring  101, 102. As a result, a gap between the recording paper on the drum 1 and the end  of the rectifier plate 5 is kept minute normally, and the amount of flowing wind  going through the cap is made extremely small, thus minimizing the bending of the  flow of ink particles caused by the wind.
