IPC: G10F1/02
Filed: 1993-06-25
Abstract: PURPOSE:To restart an automatic musical performance after the reproduction of a recording medium and the reproduction of the automatic musical perfor mance are synchronized with each other if the both becomes asynchronous with each other. CONSTITUTION:When the automatic musical performance using an automatic performance memory 208 is carried out in time to the audio reproduction of the CD 105, a musical instrument control part 201 stops the audio playback sound and waits for the device to recover from an uncorrectable state if error correction is disabled owing to a flaw, etc., on the CD 105. Once the devices recovers, the synchronous reproduction is restarted on the basis of time data in automatic performance data and time data on the CD 105.

Title: Display device
Inventor: KAWASE TOMOYUKI
IPC: G09G3/04
Filed: 1987-06-23
Abstract: PURPOSE: To increase luminance in accordance with display duty and to reduce the dispersion of display luminance or flickering among respective columns by changing the pulse width of dynamic driving scanning pulses of a display device in each column and equalizing the width of scanning pulses applied to respective columns between two periods of commercial power supply.  
     CONSTITUTION: The pulse width of column scanners K1 to K4 of respective display devices 1a to 1d to be driven by a dynamic scanning system is variably changed in each column and the total of the pulse width of scanning pulses applied to respective columns in one scanning period or a period proportional to one period is made equal in all columns.

IPC: B41J2/06
Filed: 1996-06-17
Abstract: PROBLEM TO BE SOLVED: To stabilize the recording quality in the whole spacing areas by providing recording gap measuring means at both ends aside of an ejection electrode of a head. SOLUTION: When a recording paper 5 is fed in the arrow H direction along the disposition direction of an ejection electrode 3 in a recording head 1, the recording head 1 is positioned at one end of a spacing area 4 before starting the recording operation. The recording gap between an A point and a B point is measured by sensors 7 provided at both ends. The recording head 1 spaces to the other end of the spacing area 4 so that the recording gap between a C-point and a D-point is measured.  Based on the measurement in the four points, a controlling portion controls a θ rotation mechanism and a θ rotation mechanism for finely moving a counter electrode 2 for making a correction in the θrotation direction and the θ rotation direction such that the recording gap from the ejection electrode 3 to the recording paper 5 can always be constant in the recording operation thereafter.

Filed: 1984-07-26
Abstract: PURPOSE:To correct a basic character inputted in the past easily by deciding the availability of voiced sound formation and rho-sound formation by a voiced sound/ rho-sound formation availability deciding part and converting the basic character into a voiced sound character or a rho-sound character on the basis of the decided result. CONSTITUTION:A basic character is displayed on a display 7 and its positional information is stored in a position storage part 3. When a voiced sound code or a rho-sound code is inputted, the voiced sound/rho-sound formation availability deciding part 4 decides the availability of the sequence of (voiced sound basic character + voiced character code), the sequence of (rho-sound basic character + rho-sound code) or voiced-sound formation or rho-sound formation such as the correction of voiced-sound formation of the basic character. In other case, the deciding part 4 decides an error input. When the availability of the voiced-sound formation or rho-sound formation is decided, a voiced-sound/rho-sound conversion part 5 forms a voiced-sound character or a rho-sound character and displays the formed character on the display 7.

Title: Tube end joining structure
Inventor: TAKEUCHI MAMORU
IPC: B21D39/04
Filed: 1980-11-07
Abstract: PURPOSE: To eliminate danger of hydrogen embrittlement fracture of a tube in roll joint method of tube end by providing a hollow part at a specified position of intermediate tube end part.  
     CONSTITUTION: Tube end of shapetube, especially a penstock 1 of a heavy water reactor is inserted between an outer peripheral tube 2 and an inner peripheral tube 3. The tube 3 is expanded from inside by a roll 4 and joined. A hollow groove 6 is provided on the inner peripheral part of a tube 1 with which the end of the tube 3 contacts. When inside of the tube 3 is expanded, the tube 1 that corresponds to the position of the tip of the tube 3 is expanded in the direction of outer periphery, and high residual tensile stress is generated in this part. However, owing to the groove 6, the amount of expansion of the tube 1 is reduced. Consequently, occurrence of residual stress is prevented and danger of hydrogen embrittlement fracture is eliminated.

Title: Information processor
Inventor: AINO SHIGEYUKI
IPC: G06F9/38
Filed: 1988-06-24
Abstract: PURPOSE:To prefetch an instruction at a high speed after the cancel conditions are satisfied by retrying the instruction identified by an identification means and at the same time canceling the instruction set at the stage of a pipeline and its relative information by the subsequent instructions including the one to be retried. CONSTITUTION:A circuit 134-138 identifies the specific one of subsequent instructions when a register having the possibility of conflict produces a cancel instruction during a pipeline process. A circuit 139-142 recognizes the specific instruction that carried out the cancel together with the cancel instruction. Then a circuit 102 invalidates the register number designated by the cancel instruction out of those register numbers having the possibility of conflict. When the cancel conditions are satisfied, this satisfaction is checked in plural cycles and the number of the register to be invalidated with a request for cancel is invalidated. Thus an instruction can be prefetched at a high speed after the cancel conditions are satisfied.

Title: Operation control system for chemical injection pump
Inventor: MUKASA MINORU
IPC: F04B49/06
Filed: 1979-12-04
Abstract: PURPOSE: To promote the follow-up capacity of an actual value of chemical injection to the set chemical injection amount, by providing a great-capacity injection pump controllable in its amount of injection by the length of stoke and a samll-capacity pump controllable in its amount of injection by the number of revolutions and the length of stroke.  
     CONSTITUTION: In accordance with the level of the set command, a great-capacity pump 1 is given a stroke-control signal from a control device 3 to be controlled in its length of stroke, and the portion in its charge is changed by steps. On the contrary, a small-capacity pump 2 variable in its length of stroke and the number of revolutions is taking charge in the remainder known by substracting the portion in charge of the great-capacity pump 1. Since the amount of chemical injection is finely and continuously adjusted by changing the number of revolutions of the small- capacity pump, the follow-up capacity of an actual value to the command of injection can be improved. As the adjustment is made only by changing the stroke lengths of the large and small capacity pumps 1 and 2 by steps, mechanical operations can be reduced to promote the reliability of a system.
