A percussion instrument includes a mainframe having a bottom part defining a lower surface. A head is tensioned over an inner part of the mainframe. A hoop structure is arranged over the outer periphery of the head and applies tension to the head. The hoop structure has a lower surface provided with a plurality of recesses. Female threaded connector parts are contained within the recesses. A plurality of bolts extend through the bottom part of the mainframe and engage the female threaded connector parts, to affix the hoop structure to the mainframe. The bolts extend into the bottom part of the mainframe, such that exposure of the bolts on the upper surface side of the hoop structure can be avoided.

A method and an apparatus for manufacturing tablets of moist powder which is produced by adding an additive agent such as an excipient or a binder to medical ingredients, further adding a solvent such as water, ethanol or the like, and kneading the mixture. The tablet manufacturing method comprises the steps of: preparing a first table and a second table which are intermittently rotated and driven relatively with respect to each other; supplying moist powder from a hopper into filling holes of the first table; filling the supplied moist powder into mold cavities of the second table under a pressurized condition by means of filling pins of a filling and pressurizing device at a location where the first table overlaps with the second table; relatively moving the first and second tables with respect to each other so as to level the surface of the moist powder in the mold cavities by removing the excessive powder; chamfering the surface of the moist powder by a finish-forming device; drying the moist powder by a dryer; and releasing the moist powder out of the mold cavities by a release device.

An output signal from a photodetector (3) responsive to light reflected at a phonograph record (2) is differentiated to produce positive and negative differential pulses (b.sub.1+, b.sub.1-), and the positive differential pulse (b.sub.1+) is retarded by a time length substantially equal to the time difference between the positive and negative differential pulses (b.sub.1+, b.sub.1-), while the negative differential pulse (b.sub.1-) is inverted to be a positive signal (d). The retarded signal (c) is added to the positive signal (d) so that the amplitude of the positive signal (d) becomes greater than before when the timing of the positive signal matches with the retarded signal (c). A resultant sum signal (e) produced in this way will be compared with a reference value (V.sub.TH1) to detect only unrecorded zones thereby accurately distinguishing unrecorded zones from recorded zones. The circuit arrangement therefore, comprises a differentiator (4), a circuit (D.sub.1, D.sub.2) for separating the positive differential pulse (b.sub.1+) from the negative differential pulse (b.sub.1-), a delay circuit (6), an inverting circuit (7), an adder (8), and a comparator (9).

A record disc playing apparatus comprises an address signal generating unit for generating address signals corresponding to horizontal rotational angular positions of a tone arm, a device for generating a rotational angular velocity signal corresponding to the rotational angular velocity of the tone arm, a circuit for controlling the rotation of a motor for driving a turntable, a control device supplied with the address signals and having a memory device from which is from which read out information corresponding to the addresses indicated by the address signals, and an attenuation circuit supplied with the rotational angular velocity signal and operating with an attenuation quantity, with respect to the rotational angular velocity signal, which quantity is varied by a signal from the control device. The rotational angular velocity signal corresponds to the quantity of any eccentricity of the record disc. The control device producing as output signals based on the information thus read out. The attenuation circuit supplying an output signal to the control device. The rotation of the motor is so controlled that a rotational irregularity due to any eccentricity of the record disc is corrected for.
