Title: Test circuit for d/a converter
Inventor: INAMI DAIJIRO
IPC: H03M1/10
Filed: 1987-04-16
Abstract: PURPOSE:To measure a peak value of glitch by subtracting an output of an integration device receiving a master clock from an output of a D/A converter and using a peak- hole circuit so as to detect the maximum and minimum value being the result of subtraction thereby measuring the maximum value and the minimum value of an error voltage generated at the output of the D/A converter. CONSTITUTION:A master clock CLK is inputted to an n-bit counter 1. Digital codes D1-Dn being parallel outputs of the counter 1 are increased one by one bit by the clock CLK. An output (a) of an n-bit D/A converter 2 being the object of measurement receiving the digital codes D1-Bn is a stepwise waveform having a transient phenomenon (glidge) at data changeover. Then the master clock CLK is inputted to an integration device 3. Since an expected value (analog voltage) of the D/A converter 2 is obtained at the output (b) of the integration device 3, the quantized error, the capacitance error and an errorvoltage including glitch of the D/A converter 2 are obtained by subtracting the output (b) from the output (a) at the subtractor 4. In inputting the output (e) of the subtractor 4 to a peak hold circuit 5, the maximum value of the error voltage is obtained at the output (d) and the minimum value of the error voltage is detected and held at the output (e).

Title: Compiling process system corresponding to plural code systems
Inventor: NOBA KAZUHIKO
IPC: G06F9/45
Filed: 1989-04-12
Abstract: PURPOSE:To cope with even different code systems with no change of a process logic by using the binary code of a specific character in a code system of a source program in a process logic having no dependence on the code system by reference to a correspondence table. CONSTITUTION:A syntax analyzing part 16, a meaning analyzing part 18, and a code generating part 20 must be conscious of only a certain character code respectively. These codes are previously set in a common area 21 in the form of a correspondence table 22. Then each processing part refers to the codes corresponding to each specific character of the area 21 and can use a common process logic even to different code systems. Thus a correspondence table setting process part 15 can cope with the process of a source program 10 of a new different code system just by changing only the code that is set to the table 22 and with no change of the process logic.

Abstract: PURPOSE:To attain to enhance visibility, by controlling the width or output value of the output pulse of a monostable circuit by the magnitude of electric power to be measured and keeping the brightness of an ON-and-OFF display device by changing the ratio of the lighting time and the time for putting out lights of the ON-and-OFF display device. CONSTITUTION:Electric power to be measured is converted by an electric power frequency converter 1 and the converted frequency is stepped down by a frequency dividing circuit 2 and brought to the frequency matching with a display unit by a counting display circuit 3 and electric power to be measured is measured and displayed by the display circuit 3. A monostable circuit 4 is triggered by the output pulse of the circuit 2 to output pulse output having a prescribed pulse width. The output pulse of the circuit 2 is also simultaneously outputted to a control circuit 5 and, when the speed of the output pulse from the circuit is 'slow' received in a small electric power range, the width of the output pulse of the monostable circuit 4 is made long. Whereas, when the speed of the output pulse from the circuit 2 is 'fast' received in a high electric power range, the width of the output pulse from the circuit 4 is made short. By this method, the brightness of an ON-and-OFF display device 6 is made constant to be turned ON and OFF.

Title: Controller for lockup clutch
Inventor: SUZUKI YUTAKA
IPC: F16H61/14
Filed: 1990-04-06
Abstract: PURPOSE:To control a speed difference as desired at stable accuracy by setting engine speed down to a controlled system at time of starting. CONSTITUTION:This controller is provided with a desired engine speed setting means, setting desired engine speed at time of starting, an actual engine speed detecting means, detecting actual engine speed, and a feedback control means, outputting an operating signal to an electrical actuator so as to make a difference between the desired engine speed and the actual one come to zero. In brief, at time of starting, the engine speed is controlled so as to become the desired engine speed. Consequently such a possibility that the engine speed might go up to more than the necessity is brought to nothing and, what is more, any racing is prevented from occurring. In addition, since the engine speed or a relatively large value is set down to a controlled system, control accuracy comes to such being high.

Abstract: PURPOSE:To miniaturize a device by bending a ground plate in a prescribed part and preventing the ground plate from coming into contact with parts and devices other than a destaticizing unit. CONSTITUTION:A metal plate 24 for destaticizing the charges of an electrified sheet after transfer is attached to one of the sides of the casing 18 of a transfer unit 8 via a guide member 23. The ground plate 31 composed of a plate spring is fixed on a support plate 27 with a fixing part 32. At the front end of the groung plate 31, the contact part 33 is formed in the state of being bent. By making the width of the contact part 33 smaller than the widths of the parts of the ground plate 31 other than its contact part 33, the contact part 33 is made to bend easily compared to the other parts of the ground plate 31. When the transfer unit 8 is attached to the frame of the device, the ground plate 31 is pressed to the metal plate 24 and tends to be bent by its own elasticity, however, only the contact part 33 of the ground plate 31 bends and the parts of the ground plate 31 other than the contact part 33 do not bend and are kept in the prescribed positions.
