Title: Semiconductor memory device
Inventor: KONO SHIGEKI
IPC: G11C7/06
Filed: 1999-01-29
Abstract: PROBLEM TO BE SOLVED: To obtain a semiconductor memory device which eliminates the dependence on an address of the read rate of stored information and in which the stored information can be read out at a maximum rate by providing a means by which the charging speed of a reference digit line can be changed. SOLUTION: The constitution of a reference cell matrix is made identical to the constitution of the fundamental unit of a memory cell matrix 9. The selection signal of a reference cell is made equivalent to that of a memory cell. Thereby, the rise time of a digit line is made nearly identical to the rise time of a reference digit line. Even when the rise time of the fight line is changed by an address to be accessed, the rise time of the reference digit line is changed in the same manner. A digit-line reference signal DGR is nearly equal to the intermediate value between a digit line signal DG (ON) generated by a memory cell in an ON state and a digit line signal DG (OFF) generated by a memory cell in an OFF state, and it rises quickly along the intermediate value.

Title: Cutter preventing erroneous cutting
Inventor: UCHIDA TATSUTOSHI
IPC: B26D7/22
Filed: 1998-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a cutter which can prevent erroneous cutting resulting from erroneous arrangement from being generated in an object to be cut, such as printed paper. SOLUTION: The widths W1, W2, W3 of the objects to be cut at the time of being disposed at a cutter 1 are set and stored respectively in a movement controller for the ruler 2 of the cutter 1 corresponding to the moving positions (a), (b), (c) of the ruler 2 for respective cutting stages. A sensor 6 is disposed behind a cutter body 4 along the longitudinal direction of a knife 3, so as to detect the width of the object to be cut disposed at the cutter body 4. In cutting, the ruler 2 is moved to a prescribed position, a setting value of the width of the object to be cut at this position is compared with a measured value which is measured by the sensor 6.  If both of them coincide with each other, the knife 3 is operated to conduct cutting, and if not, the operational circuit of the knife 3 is opened to take the object to be cut as being in an erroneous arrangement, and the lowering operation of the knife is prevented even when the switch is ON, thus it is possible to prevent generation of erroneous cutting resulting from the erroneous arrangement.

Title: Analog/digital converter
Inventor: SHIROTA SHOZO
IPC: H03M1/34
Filed: 1990-01-31
Abstract: PURPOSE:To prevent the accuracy from being deteriorated against the fluctuation of noise or the like of an analog input by turning off an analog input select signal till a chopper amplifier bias signal is lost and an input sampling signal is interrupted. CONSTITUTION:An analog input select signal SELi is brought into an L level for a period till an input sampling signal SAMP goes to L after a chopper amplifier bias signal TB reaches an L level. Thus, even when fluctuation due to noise is superimposed onto the analog input after the chopper amplifier bias period is finished, no fluctuation is delivered to a comparator input 2 and stable conversion with high accuracy is attained. Thus, since the analog select signal is interrupted only for a period when the effect of input fluctuation due to noise or the like is susceptible, a stable A/D converter with high accuracy is realized.

Title: Auxiliary gap member for spark plug for internal combustion engine
Inventor: TAKAMURA KOZO
IPC: H01T13/00
Filed: 1988-02-02
Abstract: PURPOSE:To stabilize spark voltage by disposing conductive matter electrically insulated from an anode and surrounding this anode. CONSTITUTION:Because the degree of expansion of corona at electrode edge part 4a(5a) is controlled by action of conductive matter 6 electrically insulated from an anode 4(5) and disposed in an enclosing tube 1 surrounding this anode 4(5), fluctuation in spark voltage at a spark gap becomes small. By setting the conductive matter 6 to have an equal potential to a cathode 5(4), potential inclination at the electrode edge part 4a(5a) becomes sharp further, and fluctuation in spark voltage becomes small further. Spark voltage can thus be stabilized.
