Title: Digital signal delay circuit
Inventor: WARISAYA KANJI
IPC: H03K5/13
Filed: 1984-08-02
Abstract: PURPOSE:To improve the noise eliminating effect by using the monostable multivibrators which are put under semistable states in the rise and fall modes of a supplied rectangular wave signal respectively, gate circuits and an FF circuit. CONSTITUTION:The input signal D is supplied to monostable multivibrators MVs 11 and 12. The MV11 is put under a semistable state when the signal D has a rise and then reset to a stable state after a time T3. The output E of the MV11 is turned into a rectangular wave signal E. While the output F of the MV12 is turned into a rectangular wave signal of a figure F. The signals E and D are supplied to an OR gate 13; while signals F and D are supplied to an OR gate 14 respectively. Then gate outputs G and H are supplied to an FF15. Therefore the output J of the FF15 is turned into a rectangular wave signal where the rise of the signal D is delayed by a semistable time T3 of the MV11 and the fall of the input D is delayed by a semistable time T4 of the MV12. These MVs are not easily affected by other input signals in a semistable mode. Thus the noise eliminating effect is increased.

IPC: G06F17/30
Filed: 1988-06-30
Abstract: PURPOSE:To shorten a retrieval processing time by making the storage of all relational data bases in a main memory device unnecessary by holding a relational name, the list of the relational names, and part of an attribute value string in the main memory device, and enabling the kinds and the numbers of attribute value strings to be changed by an on-line operation. CONSTITUTION:All the relational tables are held in a magnetic disk device 3, and a CPU2 registers the relational names and the attribute names of all the relational tables and part of the attribute value string in a main memory 1, and adversely, withdraws the attribute value string from the main memory 1 to the magnetic disk device 3. And when the attribute value string of the relational name required for the processing of a query text is already registered on the main memory device 1, the query is processed only by information in the main memory device 1, and when no required attribute value string exists on the main memory device 1, a required attribute value string is registered on the main memory device 1 by the on-line operation. In such a way, it is possible to shorten the retrieval processing time without holding all the relational data bases in the main memory device 1.

Title: Positioning controller for magnetic disk device
Inventor: HIBINO YOZO
IPC: G11B21/10
Filed: 1989-06-28
Abstract: PURPOSE:To improve the reliability of data read/write with high following accuracy by multiplying a digital input by 1/2<n> at a digital computer when the digital input reaches the maximum value of a D/A converter and multiplying the gain of an analog output of the D/A converter by 2<n>. CONSTITUTION:Position information is digitized by an A/D converter 6 and a position control circuit 7 decides a manipulation variable to track and position onto an object track. Since the position information is a discrete time signal, the manipulation variable of a digital signal being discrete time is converted into an analog signal being continuous time at a D/A converter 8, amplified by a power amplifier 9 to drive and control a voice coil motor 10. When the digital input of the D/A converter 8 reaches a maximum value, an analog output is saturated and the accuracy is deteriorated, then the digital input to the D/A converter 8 is multiplied by 1/2<n> to be decreased and the gain of the analog output is multiplied by 2<n> to be increased. Then the analog output with high accuracy is obtained and the access time is shortened and the positioning accuracy is improved.

IPC: G02F1/01
Filed: 1994-07-15
Abstract: PURPOSE: To provide an ultra-high speed optical switching element which is operative at ordinary temp. and is capable of overcoming the threshold of switching of a several tens nanosecond band. CONSTITUTION: If incident light 4 passes a first multiple quantum well structure 1 changed in the properties of light by control light 3, transmitted light 5 is so changed as to have an increased light quantity by exposure development. When this light passes a second multiple quantum well structure 2, the exposure development by this second multiple quantum well structure 2 is increased by the exposure development by the changed light during the first several picoseconds and the quantity of the transmitted light 5 is eventually increased. Namely, the intensity of the transmitted light 5 increases in the short time band. On the other hand, the second MQWS acts as an absorber and the transmitted light quantity is increased during several picoseconds in the long time zone past the several picoseconds. The long time constant is offset by the second MWQS and an off-time is shortened.
