Title: Multioutput power unit
Inventor: FUKUCHI TAKESHI
IPC: H02M3/28
Filed: 1990-09-12
Abstract: PURPOSE:To raise output stability and safety by preventing overcurrent with an overcurrent protecting means even if an overcurrent flows in either the first or second DC output, and by causing the first DC output to be in an overcurrent state with an overvoltage protecting means and causing the overcurrent protecting means to operate when overvoltage in the second DC output occurs. CONSTITUTION:An overvoltage protecting means (of the second DC output) is composed of a transistor Q3 being the dummy switch of the first DC output circuit and resistors R10, R11 of the second DC output circuit. If overvoltage appears as the second output voltage by some cause, the base voltage of the transistor Q3 rises turning the transistor Q3 on, and a current flows in a dummy resistor R8 with a low resistance value from the first DC output bringing it into an overcurrent state. This appears as increase of a primary current immediately, and the primary current exceeds a specified value. Accordingly, overcurrent is detected with a control circuit 5 by a current signal generated between the terminals of a primary current detecting resistor R4, and lowering the on-duty of a driving pulse and limiting the operation of an FETQ1 being a switching element, to prevent overcurrent.

Title: Character recognizing device
Inventor: TAKEZAWA KATSUHITO
IPC: G06K9/62
Filed: 1988-09-29
Abstract: PURPOSE:To hasten the processing time and to reduce the erroneous recognition ratio by jump-reading the character information up to the leading character information of a next line when the result of the character recognition is the jump-reading information. CONSTITUTION:A mark 102 shows a mark sheet detecting mark 101 or a reading starting position mark to instruct the reading starting position of respective lines to record the character information and a mark 103 shows a line termination mark to instruct the termination of respective lines to record the character information. A mark 104 shows the line termination identifying mark for jump- reading the succeeding character to instruct that the succeeding character information is not written in respective lines. Consequently, when the line termination identifying mark 104 is not written in the line, the information for 7 characters which can be written in the line becomes all the object of the character recognition. When the result of the character recognition is the jump-reading information, the character information is jump-read up to the leading character information of the next line. Thus, without executing the unnecessary character recognition, the erroneous recognition ratio is reduced.
