Title: Performance method of music data and music performance device using it
Inventor: TAKASAKI NAGAYOSHI
IPC: G10H1/00
Filed: 1997-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a performance method of music data and a music performance device capable of easily varying a performance speed. SOLUTION: The performance data on a piece of music and time information showing performance time are stored in a memory part (ST11). A tempo input key is operated for measuring the beat of the music and a time interval and setting the performance speed from a mean time (ST12). The data and the information are read out (ST13), and when the time interval until the next key operation does not satisfy ST15 and ST16 (ST14), the time information is processed so as to become the set performance speed (ST18), and the data are supplied to a sound source part at the timing of this information, and a musical signal is generated. The key operation satisfied ST15 is made invalid, and when satisfying ST16, the mean time is calculated newly, and the performance speed is reset. When the key operation does not exist, and ST30 is satisfied, the advance of the performance is stopped (ST31).  The processing from ST13 is repeated until the output of the data in a memory are finished. Only by changing the time interval by the operation by the tempo input key, the performance speed is varied easily.

Title: Encoder
Inventor: TSUKIJI MASAAKI
IPC: G01D5/38
Filed: 1988-05-10
Abstract: PURPOSE:To prevent laser luminous flux from exiting from the case of the encoder by detecting whether or not coherent luminous flux for measurement and a scale are in prescribed position relation and controlling the oscillation of a laser and the cutoff of laser light with a detection signal. CONSTITUTION:The luminous flux from the laser 1 is made incident on a diffraction grating 3 through a collimator lens 2.

A light emitting element 10, a condenser lens 11, and a light receiving element 12 are put in a case and when the light receiving element 12 does not light-receive luminous flux below certain intensity, a control means 13 stops the oscillation of the laser to prevent the laser luminous flux from exiting from the case 9 through a shutter mechanism, thereby eliminating adverse influence upon human bodies.

Title: Prediction alarm tone transmission
Inventor: OSAKI TAKAAKI
IPC: G06F3/16
Filed: 1986-05-20
Abstract: PURPOSE:To eliminate circuits of extension, compression and addition, etc., by using an original signal as it is in a prediction alarm tone transmission circuit which overlaps a coded sound signal with an audible sound signal, and transmits them. CONSTITUTION:In a ROM 15, an overlapped value in which respective sampled values of the audible sound signal are added to all the respective values to which the sound signal can take is written. The ROM 15 is respectively supplied with address signals from a serial-parallel conversion circuit 11 and an AND gate 14 at every sampling cycle of the sound signal. Thus, a read signal in accordance with the overlapped value in a memory address concerned is sequentially supplied to a parallelserial conversion circuit 16 from the ROM 15. The converter 16 converts the supplied signal to a serial signal, and the objective overlapped signal in which the sound signal is overlapped with the audible sound signal can be obtained. Thus, the circuits of extension, compression and addition can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To improve the productivity by adjusting a process of the series of extension of the wire, and moving a welding torch by a robot in a temporally duplicate manner to reduce the welding time and the movement cycle time. SOLUTION: During the welding at one welding part, a wire feeding equipment is driven forward to feed the wire in the forward direction, while a clamping equipment is in the released condition and does not interfere the feed of the wire. When the welding is completed, the wire feed equipment is stopped, and the feed of the wire to a welding torch is stopped. Then, the wire is clamped by the clamping equipment closer to the welding torch in the wire feed direction than to the wire feed equipment. The wire feed equipment is driven backward, and the wire is fed in the reverse direction, the excessive part of the wire part between the wire feed equipment and the clamping equipment is removed to optimize the wire length. Then, the reverse driving of the wire feed equipment is stopped, and reverse feed of the wire is stopped.  Clamping of the wire by the clamping equipment is released to set the wire free.

Title: Reset device for vocoder
Inventor: WAKE YASUHIRO
IPC: H04M7/00
Filed: 1987-05-12
Abstract: PURPOSE:To automatically restore a fault, even if it takes place, by having only to hook off the handset at least once by providing a means that detects the inoperative state of an exchange trunk connecting to a vocoder by monitoring a transmitted/received dial signal so as to reset the vocoder. CONSTITUTION:An exchange trunk inoperation detecting circuit 8 is constituted such that the circuit 8 outputs a reset signal when both 'SS' and 'SR' are inactive. In making a call from a telephone set 1, a handset of the telephone set 1 is hooked off at first. In this case, a sending dial signal 'SS' of a telephone exchange 2 is made active to inform it to a transmitter 7 that the exchange trunk is active. The 'SS' signal is sent to a line 12 via a multiplexer 11 and inputted to the exchange trunk inoperation detecting circuit 8. The exchange trunk inoperation detecting circuit 8 releases the reset to the vocoder 9 because the signal 'SS' is active.

Title: Fork pin hole machining device for turbine rotor
Inventor: FUJIWARA MINORU
IPC: B23B51/00
Filed: 1989-05-08
Abstract: PURPOSE:To avoid the core dislocation of a fork pin hole, when machined in a prefinal step where there is a narrow space between discs, by using a stretching cutting tool which is connected to a sleeve via a pin joint for a hollow cut portion. CONSTITUTION:A hollow drill 3 is connected to a sleeve 2 via a joint 7, so that when the hollow drill 3 is fixed to make positive rotation of the sleeve 2 the pin joint 7 is put therein to fix the sleeve 2 and the hollow drill 3. When the sleeve 2 is reversely rotated, the pin joint 7 is released to set the sleeve 2 and the hollow drill 3 free, allowing the stretching of a cutting tool. A machining device 1 for a fork pin hole 4 and the stretching cutting tool can be thus inserted between a prefinal-step disc 5 and a before-prefinal-step disc 6, even if there is a narrow space between discs. Also, the machining device 1 is installed at a right angle and in parallel to the side face of the disc, therefore avoiding taper from being formed in the fork pin hole 4 and improve machining precision.

Title: Detector of focusing state
Inventor: SUZUKI KENJI
IPC: G02B7/30
Filed: 1982-06-30
Abstract: PURPOSE:To enable the detection of focusing state with high accuracy by deviating the respective arrangements of lenses corresponding to two image-forming luminous fluxes from each other roughly by a half pitch and disposing the same in proximity in parallel with each other. CONSTITUTION:If, for example, an out-of-focus image 26 of a narrow slit width having a negligible width is projected on lenslet arrays as shown in the figure, the luminous flux is made incident only to the one lenslet with one row of photodetectors in the prior art and is therefore judged to be focusing and in the worst case, the out of-focus is not detected unless the width (d) of the out-of- focus image is made equal to the pitch P of the lenslet. If the two photodetectors are used in contrast with the prior art, the luminous flux is judged to be focusing on the lenslet array 25-1 but the luminous flux is made incident to the two lenslets 27-1, 27-2; therefore, the out-of-focus is detected.
