A key-driving/detecting mechanism for performing automatically a keyboard instrument is constituted by a plurality of keys arranged on a key bed, each key being rotatable about a balance pin secured to a balance rail, and an electromagnetic device interposed between a lower surface of each key and the key bed at a position to the rear of the balance pin. Each electromagnetic device comprises an electromagnetic oil mounted on the key bed and a permanent magnet secured to a rear surface of the key. The simplicity of the key-driving/detecting mechanism is implemented by this disposition of the electromagnetic device. In a modification a pair of electromagnetic devices are provided in front of and in rear of the balance pin.

A liquid crystal display device has a framework which includes a first frame for supporting a liquid crystal panel, a second frame having an upper portion for covering a peripheral portion of the surface of the liquid crystal panel and a side extending substantially parallel to the side of the first frame, and third members being in the form of clips detachably attached to the side of the first frame. The second frame is fixed to the first frame via the third members. The liquid crystal display device also includes a mechanism for changing the angle of the display.

A reduced iron installation includes transportable container having a charge/discharge mouth section provided with a sealing valve and a plurality of support legs and is arranged for 180.degree. rotation between a charge condition under a furnace to a discharge condition supported over the mouth of a storage tank via its legs, a weighing device for said container in its discharge condition, and a cluster remover disposed in the storage tank mouth and having a sealing valve which opens and closes, in response to detection signals from the weighing device indicating that the container is charged or empty, respectively. The cluster remover includes a grizzly feeder disposed obliquely within a cylindrical casing which is supported via an anti-vibration mounting on a fixed support surface, and a vibrating machine mounted on the casing.

The present invention relates to a hot briquetting apparatus for producing reduced iron briquettes comprising a container for receiving high temperature reduced iron; a storage tank connected to and located underneath the container for storing reduced iron and a hot briquetting machine located at a bottom opening of the storage tank. The improvement involves a means for charging residual reduced iron powder, carbon or mixtures thereof as well as an inert gas into the storage tank, said charge means connected to the storage tank and penetrating into the storage tank so that it is attached in a fluid-tight manner; said powder, carbon, inert gas, etc., being funneled into the storage tank in specific proportions in response to control means which are activated by a temperature sensor in contact with the reduced iron within the storage tank.

In the construction of a damper assembly for musical instruments, the conventionally used swingable damper lever for operationally relating a key to an associated damper wire is omitted and the swing movement of the key is either directly and indirectly converted into a corresponding fairly vertical movement of an elongated damper holder via a balance weight disposed to the bottom end of the damper holder in order to avoid undesired influences caused by swinging movement of any mechanical parts. Use of a plate type damper holder further advantageously prevents undesirable twist and dancing of the damper holder. Simultaneous, even and well-controlled pressure contact of the damper head with the vibrating string assures ideal damping and acoustic effects and use of detachable balance weight enables free adjustment of touch on the key.

In a method for estimating an entrance angle of a V-ribbed belt from a flat pulley to a V-ribbed pulley, the entrance angle is estimated easily at a stage of pulley layout design.The V-ribbed belt 10 forms a track which enters at an entrance angle of approximately zero degree (substantially perpendicular to a plane that includes an axis 3a of rotation) into the flat pulley 3, is wound along the outer peripheral face of the flat pulley 3 without deviating in the axial direction thereof, and extends substantially linearly from a winding end point c at the flat pulley 3 to a winding start point d at a drive pulley 1. The entrance angle α of the V-ribbed belt 10 from the flat pulley 3 to the drive pulley 1 is obtained on the basis of the track of the V-ribbed belt by, for example, a three-dimensional CAD or the like.

摘要:
A finger-pressure substitutive stimulator comprises a supple, net-like sheet member having many stripe-like projections on one surface thereof and formed of various hard or semi-hard synthetic resin materials. The finger-pressure substitutive stimulator is fixed to the surface of the skin of a human body at a part to be treated using an appropriate fixing means—e.g., commercially available adhesive tapes, bandages, and supporters—or an adhesive sheet fastened to the smooth rear surface of the sheet member; it serves to ease or remove pain by correcting such ailments as rheumatism, neuralgia, shoulder stiffness, lumbago, and visceral disorders. The stripe-like projections pressed against the skin surface provide uniform, sustained stimulation to the peripheral nerves in the human body surface layer over the entire wide region to which the stimulator is attached and effectively correct disorders and abnormalities of the human body, thereby removing or easing pains. Due to the net-like structure and suppleness of the sheet member, one or a small number of stimulators can provide effective and sufficient stimulation to a wider region than conventional stimulators while easily conforming to a curved shape of a part to be treated and ensuring air permeability to the skin surface.
