Title: Musical sound reproducing device
Inventor: SHIMIZU MASAHIRO
IPC: G10H7/02
Filed: 1994-05-31
Abstract: PURPOSE:To extend or shorten a reproduction time without varying the pitch of PCM-recorded music waveform data and deteriorating the sound quality. CONSTITUTION:The sound-recorded waveform data are divided into note units according to the specifications of a tap point TP(i) and a division point BP(i), and the waveform data are read out by extending or shortening a read time in note units according to the expansion or shortening of the reproduction time. Namely, when a sound recording time is shorter than the reproduction time, waveform data of respective notes are read out at the same speed with the sound recording and this read is quit halfway. When the sound recording time is longer than the reproduction time, the waveform data on the notes are read out at the same speed with the sound recording and a partial section of the respective notes is looped to make an adjustment to the reproduction time. Consequently, the read speed does not varies, so there is variation in neither pitch nor sound quality and the reproduction time can optionally be set.

Title: Lubricating oil feeder for engine
Inventor: MUNETOU TAKASHIGE
IPC: F01M1/02
Filed: 1979-09-14
Abstract: PURPOSE: To supply lubricating oil to a combustion chamber without excess and deficiency, by operating the flow control lever of a metering pump through simple link units depending on both the degree of opening of a throttle valve and the temperature of an engine.  
     CONSTITUTION: When a throttle valve 2 is fully opened while the temperature of cooling water of an engine is low, a throttle valve lever 4 is swung upward and the upper and lower links 8, 9 of the first link unit 7 are pulled upward. As a result, the flow control lever 6 of a metering pump 5 is also swung upward to increase the quantity of supplied lubricating oil. At that time, the link unit 7 is bent to an obtuse angle in the position of a pin 10 because the link unit 7 is coupled with the horizontal link 15 of the second link unit 13, so that the swing of the lever 6 is made relatively large. When the temperature of the cooling water becomes high, a pin 16 is moved down to the bottom of a slot 17a by the action of a thermowax pellet 12 to make the swing of the lever 6 larger.

Title: Device for correcting fluctuation of time axis
Inventor: TAKEDA KATSUMI
IPC: G11B20/02
Filed: 1982-07-09
Abstract: PURPOSE:To prevent a side lock phenomenon, by providing an AC coupling circuit to an electronic time axis fluctuation correcting device of an information reproducer such as video disc player for bringing a DC voltage of a VCO input signal into a fixed bias. CONSTITUTION:An output signal of a phase error circuit 7 is amplified and processed at a phase compensating circuit 8a, and inputted to a VCO9 via an AC coupling circuit, a buffer and a bias amplifier 13 provided in a fixed biasing circuit 10. If an external disturbance such as dropout is mixed in an extracted reference signal in this case, an excess error signal is inputted to a phase comparison circuit 8a. A large amplitude signal effected with the signal appears at an output of the phase comparison circuit 8a and the VCO9 responds to it. Although a CCD2 is going to transit to a state delayed by one horizontal scanning period for a time determined by a CR time constant of the AC coupling circuit 11, since an output stage of a bias amplifier 13 is not subjected to a DC fluctuation because of the AC coupling, a set DC voltage for driving the VCO2 is kept again. Thus, the CCD2 keeps the normal delay state against a reproduced video signal 1, allowing to prevent the generation of the side lock phenomenon and the generation of the resulting beat disturbance.
