Title: Micro-computer peripheral equipment controller
Inventor: RONARUDO JIEI RAASON
IPC: G06F13/42
Filed: 1990-09-18
Abstract: PURPOSE: To effectively compensate an access restoring time by providing an access restoring means for compensating the difference of access restoring times at a peripheral equipment, a control processor and an input/output bus. CONSTITUTION: A control signal is generated in response to an MCA control signal from a micro-charmel architecture(MCA) and an interruption signal from a microprocessor through the use of address information decoded by an address decoding part 101. A command processing part 102 includes a logic such as supply an access restoring time for a keyboard and other necessary peripheral devices, a restoration time compensation circuit, at the time of operation, senses the finish of access to the keyboard controller of an MCA bus to start a counter through the use of this information, and the counter counts a selectable quantity concerning the specific quantity of a restoring time necessary for a related peripheral equipment. Thereby an access restoring time is effectively compensated at the time of executing the interface of a central processor and a peripheral equipment.

Title: Digital loop filter circuit
Inventor: KAMIYAMA TADAHISA
IPC: H03L7/06
Filed: 1993-09-10
Abstract: PURPOSE:To reduce circuit scale and to accelerate operating speed by composing a loop filter to be used for a digital PLL circuit of an adder, subtracter and bit shifter without using any multiplier. CONSTITUTION:An adder 5 inputs a value for which an output signal at certain time (t) and a value [Y(t-1)] outputted from the adder 5 at time (t-1) are shifted for (n) bits so as to be enlarged, the Y(t-1) is subtracted later and further, those values are shifted for (n) bits so as to be reduced. The output from the adder 5 is shifted for (n) bits so as to reduce the value and outputted later as well. Since the arithmetic of the adder 5 is performed with the value of 2<n>-fold of the input signal, accurate arithmetic is enabled. On the other hand, by changing the value of (n), the effect of the filter can be adjusted to any suitable degree.

Title: X-ray mask and method of measuring interval between the mask and substrate to be exposed
Inventor: HORIUCHI TOSHIYUKI
IPC: G03F1/22
Filed: 1989-09-25
Abstract: PURPOSE:To accurately measure absolute value of a proximity interval between a X-ray mask and a substrate to be exposed by providing a back etching region provided with a X-ray absorber formed in a pattern on a X-ray transmission thin film and a hole passing front and rear surfaces of a mask substrate. CONSTITUTION:A back etching region 24 in which a X-ray transmission thin film 23 formed in a pattern with a X-ray absorber 22 is extended on a X-ray mask 21, a back etching region 25 in which the absorber 22 is formed on a whole surface, and a hole 26 passing front and rear surfaces of the mask 21 are provided. Since a hole is formed at the mask to eliminate presence of a solid intermediate except the atmospheric gas between gap sensors 27, 28 and a substrate 29 to be exposed, the position of the substrate can be accurately detected. Since the positions of the mask 21 and the substrate 29 are detected by the sensors 27, 28 placed on the rear surface side of the mask, reference points of the sensors 27, 28 can be calibrated by using a calibration substrate such as a plane substrate, etc., and an absolute gap between the mask and the substrate to be exposed can be obtained. Thus, the absolute value of a proximity gap between the mask and the substrate to be exposed can accurately be measured.

Title: Frequency dividing circuit
Inventor: FUJITA MASAAKI
IPC: H03K23/00
Filed: 1986-10-20
Abstract: PURPOSE:To generate a frequency division output fed to a synchronizing counter of the next stage in a normal state by latching a frequency division output signal of n stages of T flip-flops (T-FFs) by a D flip-flop (D-FF) and a reference clock and using its output as a synchronizing clock of the synchronizing counter thereby compensating a delay due to the T-FFs. CONSTITUTION:A T-FF1 is operated by the rising of a reference clock A after a reset signal (u) is released to obtain an output B. An output C is obtained by operating a T-FF2 by the rising of the output B. Then a T-FF3 is activated by the trailing of the output C and a T-FF4 is operated by the trailing of an output D similarly to obtain an output E. The output E is retarded by 1T via a D-FF5 with respect to the reference clock K to correct the leading of the output of the T-FF2 by 1T and to correct a delay time T4 at the output E into a delay T5 by one stage of the D-FF with respect to the reference clock K. Then the inverted output of the D-FF5 is used for the synchronizing clock of the synchronizing counter 6 to obtain outputs G and H.

Title: Display device used in common with input
Inventor: HARADA HIROSHI
IPC: G09F9/00
Filed: 1990-09-20
Abstract: PURPOSE:To obtain the display device in common use with input which has good operability and lessens fatigue by disposing a display part atop a box- shaped body housing a control section and providing a mirror erected at nearly a perpendicular angle at the rear end thereof. CONSTITUTION:The display part 2 is mounted atop the body 4 in such a manner that a data input area 2b comes just before the same and the mirror 5 is installed nearly perpendicularly at the rear end thereof in such a manner the data display area 2a enters the visual field. The body 4 is placed on a low desk to allow inputting while the elblow is held placed horizontally thereon. The data display area 2a is visible through the mirror 5 at the eye height. The optical path emitted from the area 2a refracts toward the mirror 5 and arrives at the mirror 5 on a gentle slope 6a of a large incident angle if a filter 6 having a saw tooth-shaped section is fixed to the front surface of the area 2a by directing the gentle slope 6a toward the mirror 5. This light is, therefore, visible through the mirror 5 but reflects totally on a steep slope 6b of the small incident angle and, therefore, the light is not directly visible from the front. The erect image is thus visible.

Title: Cloth quantity detector for washer
Inventor: ISHINO TAKASHI
IPC: D06F39/00
Filed: 1989-09-27
Abstract: PURPOSE:To judge the quantity of cloth precisely and to perform precise operation cycle control corresponding to the quantity of cloth even a large quantity of cloth exist by obtaining the accumulating total of voltage cycle time at every repeat of turning on/off of a motor, and detecting the quantity of cloth by adding prescribed time on the accumulating total when no voltage cycle time is detected when the motor is turned off. CONSTITUTION:In a cloth quantity detecting cycle, inversion stirring with on-time for 0.4sec and off-time for 1sec is performed, and the counter electromotive force of the motor 8 when a rotor 6 is rotated with inertia in off-time is detected with the terminal voltage of a capacitor 8a for motor 8 driving, and it is converted to a DC rectangular pulse, and the quantity of cloth is decided by measuring a time t1 between the pulses. Even when the measurement of the pulse time width t1 for even one time out of ten times is missed in the case of applying a load exceeding a certain level, it follows that a rank must be set at a large quantity load i.e., the same cloth quantity rank as that of a rated load. Therefore, a certain constant value is decided in advance when no pulse time width t1 is impossible to measure. The value is decided setting a measurable maximum cycle as reference. In such a way, it is possible to bracket the cloth quantity rank with especially capacitance in the neighborhood of rated capacitance.

The thus prepared filler is filled into a column 4 and an activity measurement-targeted enzyme (e.g., trypsin) 2 is introduced into the column 4 with a pump 1. The produced decomposition products (e.g., para-nitroaniline) of the substrate is quantified with a detector 5 to measure the activity of the enzyme.
