Title: Digital to analog converter
Inventor: ISHII YOSHINORI
IPC: H03M1/82
Filed: 1982-06-30
Abstract: PURPOSE:To output the voltage across a capacitor as an analog voltage and to simplify circuit constitution, by applying the capacitor with a digital signal applied between one terminal of a resistance element and the ground through a diode. CONSTITUTION:When there is a pulse input which holds a terminal A at a high level, the capacitor C is charged through a diode D1 and the output at an output terminal Va increases. On the other hand, when there is a pulse input which holds a terminal B at a low level, the capacitor C is discharged through a diode D2. At this time, the output Va varies in accordance with control based upon the frequency of the charging and discharging of the capacitor C, i.e. the digital signal. Then, the constants of the R and C are set to proper values to obtain the output Va with small step width.

Title: Developing device
Inventor: YAJIMA TAKESHI
IPC: G03D5/04
Filed: 1987-05-11
Abstract: PURPOSE:To obviate generation of unequality in development and film thickness of a disk-shaped master disk by coating a discharge port for a developing soln. with a porous body. CONSTITUTION:The master disk 2 is fixed onto a turn table 1.

Title: Analyzing method for program abnormality
Inventor: TAKADA SHINGO
IPC: G06F11/28
Filed: 1991-05-20
Abstract: PURPOSE:To facilitate the analysis of program abnormality by reading in instructions to the point of time when the abnormality of a program occurs, and executing operation reverse to normal operation in reverse order for every instruction, and detecting an abnormal effective address. CONSTITUTION:In the case that the abnormality occurs during the execution of the program, the instructions from initial state to the time of the occurrence of the abnormality are read in (step 1). The instruction is converted into the reverse operation, for instance, addition is converted into subtraction (step 2). The converted instruction is executed in the reverse order from a point where the program stops (step 3). Next, it is decided whether the instruction was executed normally or not (step 4). If it is decided to have been executed normally, the effective address of the instruction is counted down (step 5). If count down is normal, the next instruction is read in (step 6, 7). If the execution of the instruction or the count-down is abnormal, its effective address is outputted (step 8). Thus, the abnormality of the program having occurred can be easily analyzed.
