Title: Fluid mixer
Inventor: HASHIMOTO NOBUO
IPC: B01F5/06
Filed: 1986-07-05
Abstract: PURPOSE:To obtain a fluid mixer easy to manufacture, by a method wherein a spiral shaft having a spiral groove carved therein spirally is engaged with a cylindrical pipeline having a spiral groove carved therein spirally and the cross-sectional area of said pipeline is made smaller as a fluid advances in the flow direction. CONSTITUTION:A fluid A injected in an inflow port A1 flows along the clockwise revolving spiral groove 2b formed in a pipeline 2 and the counterclockwise revolving spiral groove 3b of a spiral shaft 3 to flow in a state divided into two. The fluid B injected in an inflow port B1 flows along spiral grooves 2a, 3a. When the flow of the fluids A, B advances, the divided surfaces of the partial streams of the liquids A, B generate facial contact. Since these contact surfaces are different in flow direction, turbulent flow is generated to bring about turbulent flow mixing. When the flow of the liquids further advances to reach the connection parts of screw threads, the turbulent flow mixing is once interrupted and the next turbulent flow mixing is promoted. This turbulent flow mixing is repeated to sufficiently mix both fluids. Since the cross-sectional area of a fluid passage 30 becomes smaller as the fluids advance in the passage direction, the flow speed of the fluids becomes gradually higher.

IPC: G11B20/02
Filed: 1981-10-05
Abstract: PURPOSE:To prevent deterioration in picture quality, by providing a home VTR with an amplified whose high frequency range is emphasized by the inductance of a video head and a parallel capacitance, the negative feedback circuit of an amplifier including an LPF, and an FM peaking circuit. CONSTITUTION:A signal reproduced by a video head 1 is coupled to the secondary side of a rotary transformer 2 and sent to a 1st-stage regenerative amplifier 4. The resonance between the inductance of the head 1 and a fixed capacitance 3 provided at the input side of the amplifier 4 is utilized to perform peaking at the peak frequency of an FM carrier, and the signal is fed back negatively to the input side through the negative feedback circuit consisting of resistance 5-7 and a capacitor 10. This negative feedback circuit constitutes an LPF to reduce the amount of high-frequency negative feedback. Thus, variance in frequency characteristics due to variance of the head 1 is compressed and then the signal is inputted to an FM signal peaking circuit 9 through a trailing-stage regenerative amplifier 8. The circuit 9 obtains original regenerative equalization characteristics to reduce deterioration in picture quality.

Abstract: PURPOSE:To prevent the rupture of a transistor by a method wherein the change of a rectified DC voltage is detected and a switching transistor, constituting a switching system stabilizing power source circuit, is intercepted when the DC voltage has exceeded a given value. CONSTITUTION:When a rectified voltage, exceeding a specified voltage determined by resistors R2, R3 and a Zener diode D6, is impressed on the point of intersection of a smoothing capacitor C1 and the resistor R2 in this circuit, the Zener diode D6 turns on. Then, the transistor Q2, Q4 of a switching circuit also turn on and, therefore, the base and the emitter of a switching transistor(SWTr) Q1 are short-circuited and are brought into OFF condition whereby the collector current of the SWTr Q1 bia an induction T1 is interrupted. Accordingly, the induced voltage of the inductance T1, which is impressed on the collector of the SWTr Q1, is limited and the operating curve of the transistor in this case is within a safe operation area in a diagram whereby the possibility of the rupture of the transistor may be eliminated.

Title: Document register and document retrieving device
Inventor: IMASATO SHIYOU
IPC: G06F17/30
Filed: 1991-06-28
Abstract: PURPOSE:To automatically extract a keyword without using excess data such as a dictionary by providing this document registering/retrieving device with a document coding means, a document registering means and a document index storing means for storing corresponding relation between a superimposed code and a document. CONSTITUTION:The document coding means 1 converts a document to be registered or a keyword applied to the document into a superimposed code. When the document is an object to be registered, the keyword is automatically allocated and manual keyword application is unnecessary. The document registering means 2 allows a bit string obtained by the means 1 to correspond to the document and stores the correspondence in the document index storing means 3. The means 3 correspondingly stores the bit string and the document. Since the keyword is automatically allocated, labor for registering the document can be reduced, and since large data such as a word dictionary are not used, the number of memories or disks to be driven can be reduced.

IPC: H04L29/06
Filed: 1991-06-28
Abstract: PURPOSE:To prepare a minimized state transition diagram without redundancy and to efficiently prepare a satisfactory program without redundancy by automatically and surely removing the overlapping of transition information in the state transition diagram having tree structure. CONSTITUTION:An edition part 2 edits graphic information inputted from an input part 1 and prepares the state transition diagram having the tree structure. An equivalent state judgement part 3 successively compares transition information groups concerning the two arbitrary states and when these groups are equal, it is judged that the two states are equivalent. While remaining the transition information group concerning one state judged as the equivalent state, a transition information reduction part 4 erases the transition information group concerning the other state and replaces a state number in the remaining state transition diagram. Thus, the minimized state transition diagram is automatically generated by repeating such a processing until no equivalent state exists.

Filed: 1997-06-16
Abstract: PROBLEM TO BE SOLVED: To shorten a reproduction time by reading first data after sectors next to an error sector when the error sector occurs while a plurality of sectors of a range not filling one round of a track are being reproduced, and reproducing the error sector when an apparatus reaches the error sector. SOLUTION: When an error sector that cannot be corrected occurs during reading of sector data, a system controller 14 calculates a time passed after the error sector and calculates an estimated wait time from a sector being read to the error sector. When the apparatus while continuing the reading reaches immediately before an estimated position, a focus tracking control circuit 6 is controlled to move the apparatus to an inner circumference of the track. When the apparatus comes to a position of the error sector, the apparatus reads data again with monitoring sector numbers and reloads a correction and buffer RAM 10. After the reloading, a correction process and an EDC(error detection code) check for blocks are carried out again.
