Title: High-frequency leakage transformer
Inventor: YUHARA KOUHEI
IPC: H01F38/08
Filed: 1982-09-03
Abstract: PURPOSE:To reduce a leakage flux penetrating the winding, reduce an excess current loss, and prevent overheating of winding part, by performing winding for the primary winding and the secondary winding by disposing them radially around the main leg of iron core with a circular cross section, and forming the surface opposing the return leg of the pass core in a concentric arc with respect to the main leg. CONSTITUTION:A main leg 2 is made to have a circular cross section so that a specified cross section can be obtained with the minimum length of the external periphery. As a result, the length of winding with a specified number of turns can be minimized and the resistance loss of the winding is reduced. Furthermore, an end surface 9a opposing a return path leg 3 of a pass core 9 is formed so that, when seen from the axial direction of the main leg 2, it will form a virtually concentric arc with respect to the main leg 2. To obtain desired magnetic characteristics, this construction makes it possible to reduce a radial spacing 8 between the end surface 9a of the pass core 9 and the peripheral surface of the winding 5. Hence, it is possible to reduce an eddy current loss by reducing the magnetic flux penetrating the winding 5.

Title: Supporting mechanism for working machine with buffer characteristics
Inventor: SASAKI MASAHIRO
IPC: E02F3/80
Filed: 1981-09-30
Abstract: PURPOSE:To prevent the breakage of the snow-blade of a vehicular loader, etc., by effectively applying a fluid pressure buffer action by a fluid pressure control circuit, a dynamic buffer by shear pins and buffer transmitters, and elastic buffer by a buffer part consisting of elastomers. CONSTITUTION:In case where the speed of impaction acting on a working machine 4 is slower than that of fluid pressure buffer, fluid pressure buffer action is made by the extension and shrinkage of a pair of fluid pressure cylinders 10a and 10b. Also, when the speed is faster than that of the fluid pressure buffer action, fluid pressure buffer action is made by the extension and shrinkage of fluid pressure cylinders 10a and 10b, and then dynamic buffer action is made by the shearing of a shear pin 32 and the integral turning of a working machine 4, cylinder mechanisms 10a and 10b, and a buffer transmitter 8. Furthermore, when the buffer transmitter 8 comes into contact with the stopping face 24b of the projection 26b of the supporting frame 6, buffer action is further made by the cylinder mechanisms 10a and 10b. After this, the impaction is absorbed by two actions, fluid pressure buffer action by the cylinders 10a and 10b and elastic buffer action by the elastic deformation of the buffer part 28.

Filed: 1982-09-03
Abstract: Mechanised mail sorting offices require packets to be sorted according to destination into one of many bags. A typical mechanised system includes a loading mechanism for transferring packets from stationary input pockets onto a continuously moving sequence of containers which pass all destinations in turn and unload as required. The system according to the invention consists of a number of separate self powered single trolleys (TL) which run on a tracking network. Each trolley (TL) is adapted to be programmed with the route to be taken to the destination of the packet(s) loaded into it. The trolley (TL) co-operates with en-route track-side signposts (TSB) enabling steering means (SM) in the form of a guide arm at the front of the trolley (TL) to guide the trolley around the tracking network to and from its required destination for unloading its package into a bag. Programming is done by operators at induction stations (ISA, ISB, ISC and ISD) at sidings in the tracking network while the trolleys are stationary.

Title: Image reader
Inventor: TANIMIZU HIROMI
IPC: H04N1/19
Filed: 1997-06-12
Abstract: PROBLEM TO BE SOLVED: To avoid deviation in a read position even when an image is read by the reader adopting a light source changeover system by allowing a read element to read the image for the number of blocks more than the number of RGB light sources within a motor feed time of one line and using read results of the three blocks among the blocks for valid data. SOLUTION: A CCD image pickup element 5 reads an image for 4 blocks or over within a period equivalent to one line where a motor M is moved in the subscanning direction and reads an image by an R light source, an image by a G light source, and an image by a B light source for the initial 3 blocks. A system control section 9 sets an IMGCO signal to a 'high' level in matching with a timing when the CCD image pickup element 5 provides an output of luminance information by the R, G, B light sources and the image signal for that time is received by an image processing section 8, where the image is processed. The IMGCO signal is set to a 'low' level for other periods and the signals for that time is not received. Thus, only data for the 3 blocks read by the three RGB light sources are used for valid data, which are processed and the processed data are outputted.
