Title: Semiconductor memory circuit
Inventor: SATOMI KATSUJI
IPC: G11C11/413
Filed: 1990-07-23
Abstract: PURPOSE:To easily design a memory cell peripheral circuit by providing a circuit selecting and dividing a word line for writing with a column decoder signal between memory cell arrangements and performing the access of only the memory cell with an address indicating an address signal. CONSTITUTION:A word line 27 for writing selected by a low decoder signal is further divided into four with a column decoder signal by using a NAND circuit 32 and an inverter circuit 33 periodically positioned between memory cell arrangements to be separated into a positive phase 21 and a negative phase 22. Therefore, one-line memory cells in the horizontal direction is not selected at the time of writing but selected by the column address, further only the one-fourth of memory cells is selected. Thus, the memory cell peripheral circuit is easily designed by providing the circuit selecting and dividing the word line for writing in the horizontal direction for each memory cell by one address.

Filed: 1983-10-19
Abstract: PURPOSE:To automatically calibrate the offset voltage of a photometry circuit by setting the reference value of an operational amplification means according to output of the amplification means during the charging of a capacitor for photometry through a switching circuit. CONSTITUTION:While photometering is conducted, the transistor as switching element in a photometry circuit is turned ON with a control circuit 8 and causes a capacitor 2 for accumulating charge corresponding to photometering to be discharged while making terminals 6b and 6c of an analog switch 6 non-conducting. Then, the offset voltage of the photometry circuit due to a transistor 3, amplifier 4 and the like as outputted from the amplifier 4 for amplifying the accumulated charge of the capacitor is fed to the circuit 8 through an operational amplifier 5. Consequently, the set reference value of the amplifier 5 changes according to the offset voltage with the circuit 8, a D/A converter 7 and the like and thus, the offset voltage of the photometry circuit is automatically calibrated not affected by the level of the offset voltage thereby accomplishing the photometry without offset errors.

Title: Actuating device for aperture blade
Inventor: KIYOTA MASATO
IPC: G03B9/02
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive actuating device capable of using an electromagnetic plunger as a drive source. SOLUTION: A collar part 12c can move a movable member 14 to the left against a spring 15, by the energization of the electromagnetic plunger 12. At this time, the movable member 14 rotates an aperture blade 18 counterclockwise by a pin 14c. Even if the energization is stopped and the collar part 12c is returned to an original position, the movable member 14 is stopped after its slight follow-up by the fitting relation of the end part 16b of a locking pin 16 and a revolving groove 14a. At this time, an opening part 18a is overlapped with the opening part 11a of a base plate 11, so that an aperture for an optical path is regulated by the opening part 18a. When the plunger 12 is energized again, the movable member 14 is slightly moved to the left and when the energization is stopped, the movable member 14 is returned to the state of the figure.  Therefore, even if the energization of the plunger 12 is stopped, each of large and small optical path aperture states can be surely kept.

Title: Frequency synthesizer
Inventor: WATANABE NOZOMI
IPC: H03L7/197
Filed: 1989-07-31
Abstract: PURPOSE:To decrease a frequency switching time when a high frequency is outputted at a small channel interval or a small channel interval is provided by providing an oscillation section generating a signal of a local frequency and a mixing section. CONSTITUTION:A reference oscillator 11 generates a signal of a reference frequency and an oscillator 18 generates a signal with a local frequency fLO. Then a mixer 17 mixes a signal from an oscillator 15 with a signal from the oscillator 18, outputs the result to an LPF 19, where a high frequency component is eliminated and the result is outputted to a variable frequency divider 16. Moreover, a fixed frequency divider 12 frequency-divides the signal from the oscillator 11 and a phase comparator 13 compares the signal from the frequency divider 12 with the signal from the frequency divider 16, and outputs the signal proportional to the error to an LPF 14. The LPF 14 extracts a high frequency component of the signal from the comparator 13 and outputs the result to a voltage controlled oscillator 15 end the oscillator 15 based on the signal from the LPF 14 outputs a synthesizer output signal with a frequency fOUT to an output terminal 40. Thus, the reference frequency is increased to quicken the loop response speed, thereby decreasing the frequency switching time.
