Inventor: OBARA HARUKI
IPC: B23H7/10
Filed: 1987-09-25
Abstract: PURPOSE:To contain a wire with high density through prevention of twist of the wire during recovery and to enable enough containing of the wire, by a method wherein a tempering means by intermittent energization is situated on a wire running between a hoisting roller and a wire recovery box, and the wire is contained in a folding form. CONSTITUTION:A wire 12 passing a lower guide is discharged to a wire recovery box 19 in a state to be nipped between a hoisting roller 17 and a pinch roller 18. Since the secondary voltage of a slider transformer 21 is applied on the roller 18 and an insulated metallic recovery box 19, when the tip of the wire is brought into contact with the recovery box 19, the wire 12 between the roller 17 and the recovery box 19 is charged with a current of approximate 5A. Thereby, the wire 12 is heated to a high temperature, and is tempered and becomes limp, and is contained in a snakelikely wound state. An on-off timer 25 is located between the other end on the secondary side of the transformer 21 and a brush 23 making contact with the roller 18, and by performing intermittent energization to the wire 12 running between the roller 17 and the recovery box 19, the spent wire 12 is contained in a folded manner in the recovery box 19.

Abstract: PURPOSE:To improve an output waveform, and to contrive miniaturization and lightening of the titled amplifier by providing a main magnetic flux loop path equipped with a first saturable core, a magnetic shunt core, an auxiliary magnetic flux loop path equipped with a second saturable core and a control winding wound at the extending part of the first saturable core and shifting the magnetic flux of an input winding at a magnetic shunt core. CONSTITUTION:A magnetic shunt core 14 shunts a part of the magnetic flux of a main magnetic flux loop path to outer legs 28 and 30, adjusts an output voltage, attenuates higher harmonics and minimizes the waveform distortion of the output voltage. A second wound core 22 is arranged so as to overlap with the lower half part of a first wound core 12 and a part of a first saturable core is magnetically saturated. Next, a control winding 24 is connected to a DC power source, second and third core parts 12b and 12c are magnetically saturated, the output voltage of an output winding 20 is lowered because a magnetic flux to cross with an output winding 20 is minimized. When a DC current supplied to the control winding 24 is minimized, the output voltage is reduced. Since the single control winding can be adopted and respective wound cores and respective windings are arranged in the same plane, super-thinning and compacting can be achieved, a magnetic shunt is provided at a main magnetic flux loop path, and therefore, the higher harmonics are attenuated and the waveform distortion of the output voltage can be improved.

Abstract: PURPOSE: To provide a musical performance information output device which can prevent a musical performance from being delayed due to an external sound source, etc., which is giving the real musical performance, and an automatic playing device equipped with the device. CONSTITUTION: When data read in S44 is control data and an MIDI output mode is an all-data output mode (i.e., '1') ('YES' in S52), no external output is performed if the current and last control data are the same ('YES' in S53), but when the data are not the same, ('NO' in S53), the current control data is converted into a MIDI signal, which is outputted to the outside (S54). Thus, when the current and last control data are the same, the current data is not outputted, but the last state is maintained as it is by the external sound source and then the same timbre with the output of the current data is eventually obtained.

IPC: G06F9/46
Filed: 1987-09-24
Abstract: PURPOSE:To reduce the hardware cost by making plural virtual computer systems share the real resources. CONSTITUTION:An application program is controlled by a virtual multiple processor 4 via either one of virtual computer systems 1-3 and an execution mode is controlled by an execution mode controller 6. In an on-line mode, the resources of the systems 1-3 have the free input/output in response to the real resources 25 and 26 via a resources/real resources correspondence controller 7. In a test mode the resources are limited to the virtual resources 23 and 24 and the input/output is cut off to the resources 25 and 26. In a parallel run-on mode the systems 1-3 themselves have no change from the on-line mode and the resources of the systems 1-3 go to the resources 23 in terms of the output in a parallel run test mode, then go to the resources 25 in terms of the input respectively. Thus the computer system cost is reduced.

Abstract: PURPOSE:To provide a superconducting material composed of an element selected from Ti, Zr and Hf, misch metal, Ba, copper and oxygen at prescribed molar ratios, having a critical temperature near the normal temperature and producible and usable at low material cost and cooling cost. CONSTITUTION:The objective superconducting material has a composition expressed by formula (MM is misch metal; M is Ti, Zr or Hf; 0.3<=x<=0.8; 0.05<=y<=0.4).

Filed: 1988-09-26
Abstract: PURPOSE:To prevent the displacement of a printing head by a construction wherein the excitation of a carriage drive motor is inhibited when a printing command is quiescent for a predetermined time, and at the restart of the excitation a carriage is returned to a reference position and, thereafter, traveled. CONSTITUTION:When a carriage travel signal is supplied to a printer, drive pulses (a) are generated on a terminal 100 by the number corresponding to a required travel distance. Until a time T1, exciting currents (g), (h), (i), and (j) are successively supplied to respective exciting coils 22, and a single-phase excitation according to a predetermined exciting sequence is conducted. A carriage 10 is driven to be moved to a required position by this exciting action. Then, after a predetermined quiescent time elapses from the interruption of the supply of the drive pulses (a) succeeding to the completion of a printing action, a restart signal is imparted to a printer. As a result, a drive pulse (a) is imparted as a reference position detection action signal. When the carriage 10 reaches a reference position, a reference position detection signal (k) is outputted. The carriage 10 is traveled from the reference position to the required printing position with the reception of a new printing command after the restart. Therefore, the displacement of the carriage can be prevented.

Abstract: PURPOSE:To enable an insulating layer to have the same characteristics with a polyimide resin film without using polyimide resin by a method wherein an aromatic polyamide paper is impregnated with thermosetting resin into prepreg, the insulating layer is formed of prepreg, and the insulating layer is formed 0.2mm or below in thickness and flexible. CONSTITUTION:A metal foil, a metal plating layer, or a conductive paste which can be formed into a circuit can be optionally used as a conductive layer. A conductive layer is provided onto at least one of the sides or both the sides of a board. Heat resistant resin is not especially specified in composition, but heat resistant epoxy resin, polyimide resin, or triazine resin can be used as heat resistant resin. An aromatic polyamide paper is not especially specified if it can be used for lamination. An aromatic polyamide paper is impregnated with heat resistant resin, and the resin is set semi-cured to enable the paper to serve as a prepreg. The prepreg is made to serve as an insulating layer, and it is preferable that the prepreg film is 0.2mm or below in thickness. If the prepreg film is thicker than 0.2mm, it deteriorates in folding endurance and flexibility.
