The hot air nozzle 51 having first to fourth four side walls 61 to 64 integral with one another with a ridgeline formed between the adjoining side walls. The side walls 61 to 64 is formed with orifices 68 as distributed over regions thereof corresponding to the respective seal parts 31, 35. The side walls 61 to 64 each have an outer surface facing obliquely upward.

A tape drive mechanism for a video tape recorder and an audio tape recorder. The tape drive mechanism automatically corrects the position of tape in the width-wise direction thereof without mechanically restricting the edge of tape. Sensors (8) and (8) on a tape path detect a dislocation of the tape (7) from a reference running position that may develop in the width-wise direction of the tape (7), a tape guide post (1) for attracting the tape (7) is moved in the width-wise direction of the tape, or inclination of a tape guide post (41) is changed to move the tape (7) in such width-wise direction by means of actuators (2), (42) and (62) that give corresponding displacement based on the values detected by the sensors (8) and (8), or the reel plate (57) is moved in the direction of width of tape to move the tape (7) together with the reel (24). The tape (7) having a small thickness is prevented against vertical movement on the tape path and is permitted to run stably without damaging the edges of the tape.

A blank feeder has a pair of guide rails for guiding blanks having a tubular form of square cross section to a bottom forming mandrel. The guide rails are formed with opposed recessed portions which are V-shaped in cross section for holding therebetween two corners of the blank on a diagonal thereof, and have shock absorbing means for mitigating the impact to be involved in the stiking contact of the blank with the guide rails.

Disclosed is a machine for forming viscous fluid crude material such as dough or fish-paste into a ring shape or the like. The machine has a cutter device provided with a vertical passage and cutter means arranged at the lower opening of the passage. The crude material is forcely introduced into the passage through its upper opening and extruded from its lower opening. The extruded crude material is cut off by means of the cutter means. Moreover, the passage is partitioned at least in its upper portion into a plurality of sector-shaped sections by means of a separator. Accordingly, the formed crude material can be sectioned into a plurality of portions of different tastes and/or colors.

A method comprising a first step for radiating ultraviolet rays of a short wavelength of 110 nm or longer, but shorter than 200 nm to the gas, for example, an air to be treated to generate ozone, a second step for radiating ultraviolet rays of a medium wavelength of 200 nm or longer, but shorter than 300 nm to the air treated in the first step to form active oxygen, and a third step for radiating ultraviolet rays of a long wavelength of 300 nm or longer, but shorter than 380 nm to the air treated in the second step to convert the active oxygen into oxygen molecule in ground state, at least the second and/or third step being conducted in the presence of a photocatalyst comprising particles of titanium oxide of an orthorhombic crystal system or particles of titanium oxide of an orthorhombic crystal system supporting fine particles of another metal.

Disclosed is a control apparatus for a position control motor, which allows the rotor of the motor to follow up to a command position without step out, can ensure highly reliable positioning, and is stable with respect to a variation in load. This position control apparatus comprises a position detecting section for detecting a rotor position of the position control motor, a control section for comparing an output signal of the position detecting section with a command position signal and outputting a signal corresponding to an electric current to flow in windings of the motor based on a deviation between the output signal and the command position signal, and a drive section for outputting an electric current to be supplied to the windings of the motor based on an output signal of the control section, and controls the position of the motor based on the command position signal. The control section outputs a sine-wave data signal corresponding to the command position signal from a sine-wave data table when the deviation lies within an electrical angle of 90 degrees, and outputs a sine-wave data signal, which excites the motor in such a way that the motor comes to an excitation stable point leading to the rotor position by an electrical angle of 90 degrees, from the sine-wave data table when the deviation exceeds an electrical angle of 90 degrees.

In a disc brake assembly including a caliper member mounted on a vehicle body structure in such a manner as to straddle a portion of a rotary brake disc secured for a road wheel, a friction pad supported on the caliper member by means of a pair of hanger pins to be moved toward and away from one side surface of the brake disc for engagement therewith and disengagement therefrom, the friction pad having a backing plate secured thereto to be engaged at one side end face thereof with a torque receiving portion of the caliper member in braking operation and a fluid actuator mounted within the caliper member to press the friction pad against the one side surface of the brake disc, a side projection is provided on at least an upper or lower portion of the one side end face of the backing plate for engagement with the torque receiving portion of the caliper member or on at least an upper or lower portion of the torque receiving portion of the caliper member for engagement with the one side face of said backing plate. The side projection is arranged to apply a rotational force to the backing plate in a rotational direction of the brake disc when engaged with the torque receiving portion of the caliper member or engaged with the one side end face of the backing plate.
摘要:
A two wheel type continuous extrusion apparatus has two rotary wheels having grooves receiving covering material rods, a fixed shoe block arranged therebetween and an abutement receiving a core metal wire. Covering material inlet apertures are provided for communicating passage-ways receiving the covering material rods to a covering chamber for extruding the covering material on the core metal wire to manufacture a composite metal wire. The covering material inlet apertures are inclined relative to a line connecting rotary axes of the rotary wheels such that the covering chamber is positioned on the side of supplying of the covering material rods relative to the connecting line. Consequently, a constraining force for constraining a shoe block becomes small.
