Title: Lcd controller
Inventor: YAMAMOTO TOSHIYUKI
IPC: G09G3/36
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To eliminate massive data transfer, to remarkably shorten a processing time and to update a picture similarly as usual even after a rotation display by setting a memory address of the data to be usually displayed in the lower right when an inverse display is performed on a register group setting the memory address of the data. SOLUTION: The register group 210 is a register group holding the value of the memory address where the data of a point starting a display are placed. When a 180 deg. rotation display is performed, the memory address with the data to be usually displayed in the lower right of an LCD is stored/held in the register group 210. Then, a function decrementing the address at a 180 deg. rotation display time is added to the function incrementing the address matched with a data amount per pixel at every display mode at a usual display time. Thus, at the 180 deg. rotation display time, the display is started from the final point at the usual display time, and the data are read out in the order reverse to a usual order to be displayed.

Title: Protective device for regenerative chopper device
Inventor: NARITA HIROSHI
IPC: H02M3/135
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To prevent the breakage of not only the components of a chopper device but also other components by making the energy stored in a reactor to flow reversely through a regenerative diode which is broken for some reason when a fuse blows out due to an overcurrent. SOLUTION: In a protective device for regenerative chopper device, a diode DP is connected in parallel with a serial circuit of a reactor LCH and a regenerative diode DRCH and, when the diode DRCH is broken for some reason, an overcurrent flows and a fuse FU blows out. When the overcurrent flows, the energy stored in the reactor LCH is made to flow reversely through the broken diode DRCH and a newly provided diode DP. A diode having a small current capacity can be used as the diode DP, because no current flows to the diode DP during normal chopper control. Therefore, no overcharging of an input capacitor of a regenerative chopper occurs and the components of a converter, an inverter, etc., as well as the components of the chopper device are not broken.
