Title: Oscillator circuit
Inventor: UEDA TOSHITSUGU
IPC: H03B5/30
Filed: 1978-01-18
Abstract: PURPOSE: To obtain an oscillator circuit which features the easy circuit design as well as the steady oscillation by installing the 3-terminal type electro-mechanical oscillator, the circuit which detects the phase difference between the input and output voltage for the oscillator and the voltage control oscillator which controls the frequency with the output of the above circuit.  
     CONSTITUTION: The phase difference between the input and output voltage of oscillator EMV is detected through phase detector PD, and the output controls voltage control oscillator VCO via LPF to deliver voltage V out  of frequency f. At the same time, V out  is fed back to oscillator EMV and detector PD. In case frequency f of oscillator VCO is lower than resonance frequency f 0  of oscillator EMV, the phase difference between the input and output voltage of EMV is smaller than π/2. Thus, output voltage VD of detector PD features the positive value and functions to increase frequency f of oscillator VCO. In case frequency f is higher than f 0 , an opposite action is secured to lower frequency f. And when the phase difference between the input and output voltage of EMV is equal to π/2, frequency f becomes equal to f 0  to stabilize the circuit operation. Thus, a stabilized oscillator circuit can be obtained easily.

Filed: 1989-01-11
Abstract: PURPOSE:To display a constituting element even when input/output devices are invalidated by providing the information table of the input/output devices connected to an extension bus on a bus extending unit. CONSTITUTION:When an extension bus 2 is disconnected from a system, the section between a bus adapter processor (BAP) 41 and a bus adapter (BA) 42 of a bus extending unit (BAU) 4 is made into a boundary, and the BA 42 and an input/output device 4 are invalidated. That is, when the power source of the device connected to the extension bus is disconnected, the BA 42 and lower-order devices are disconnected from the system. When the power source on the extension bus side is turned off and an operating system (OS) investigates the all release at the time of start-up, since the devices on the extension bus side are all invalidated, the system cannot grasp the conditions of the devices, and the input/output devices can be practically ignored. Thus in the OS whose constitution is determined at the time of the start-up, the constituting elements can be displayed as an effective state even when one part of the constituting elements is invalidated.

Filed: 1987-01-13
Abstract: PURPOSE:To perform excellent identification against the phase variation, etc., of an input character pattern by deforming the shape in consideration of the phase variation, etc., for the detection of the shape. CONSTITUTION:Character patterns are formed as to respective sides 1A-1D of a circumscribed frame except respective corner parts 2a-2d, and peripheral features of those characters are detected. Namely, character patterns of, for example, a side 1 when the right end is excepted from the whole and when the left end is excepted are generated and identified. Consequently, when the character pattern is as shown in a figure, a character pattern 2 displaced upward while the lower end is excepted and a character pattern 3 displaced downward while the upper end is excepted are generated. Then when peripheral features of those character patterns are detected as mentioned above, a character pattern 3 is in a shape approximating the detected value of a reference, e.g. source character pattern, so it is identified.
