A molten fiber material flow is rendered into a plurality of fibers by means of a liquid jet such as water jet in place of a pressurized gas or air. The flow moves downwardly in a vertical direction while the water jet cuts it at an inclined angle. The water jet is formed by a single nozzle or plural nozzles of a flat-jet or round-jet type.

A substantially uncurved and unwaved plywood includes at least one pair of veneers located symmetrically with respect to a middle of a thickness of the plywood and having unstraight grains which coincide with each other.A method for producing a substantially uncurved and unwaved plywood comprises locating at least one pair of veneers with identical unstraight grains in a pair of positions symmetrical with respect to a middle of a thickness of a plywood to be produced, in such a manner than the grains of the veneers coincide with each other.A simple method for continuously preparing pairs of veneers with identical unstraight grains comprises (i) peeling from a cylindrical log with unstraight fibers a continuous sheet of twice a thickness of each one of a pair of veneers to be prepared, (ii) cutting the sheet into a predetermined length to provide a thick veneer, and (iii) slicing the thick veneer at a middle of a thickness thereof to prepare a pair of veneers with equal thicknesses and with identical unstraight grains. Another simple method for continuously preparing pairs of veneers with identical unstraight grains includes slicing the continuous sheet before cutting into the predetermined length.Other methods for continuously preparing pairs of veneers with identical unstraight grains are also disclosed.

A bicycle ergometer includes an eddy current brake having a rotor assembly including an iron material having a carbon content of 0.12% or less and a silicon content of 0.35% or less, a stator provided in the rotor assembly, a plurality of exciting coils provided on the stator, and a power source for energizing the exciting coils. The ergometer includes an input panel for inputting physical attributes of the user, e.g., age and sex, a pulse sensor for measuring the heart rate of the user at rest and during exercise on the ergometer, an arithmetic control circuit for calculating a training program and heart rate range and for controlling the eddy current brake to present a load to the user which will maintain the user's heart rate in a predetermined range. The method of using the ergometer enables a user to select a physical strength program and a weight reduction program with the selected program reflecting the age, sex, and the present physical condition of the user.

A tube for exchanging heat between inside fluid and outside fluid includes a uniform cross-section portion. The outside fluid flows in an outside passage meanderingly extending in an outside fluid flowing direction. The uniform cross-section portion is disposed at least at each end of the tube longitudinal direction, and has an inside passage and a joint. The inside passage is constructed with a first inner face and a second inner face, which are spaced from each other, and the inside fluid flows through the inside passage. The joint is constructed with the first inner face and the second inner face, which are connected to each other to increase a pressure-resistant strength.
