Abstract: PURPOSE:To obtain a photogravure process roll facilitating the fitting of rotary shafts to a cylinder and being light in weight, by forming the cylinder 1 of an extruded form material of an aluminum alloy having at least three radial joint walls, and by making the rotary shafts project outward with respective one end fixed on the inner surface in each of the opposite ends of an inner wall. CONSTITUTION:A cylinder 1 is formed of an extruded form material of an Al-Mg-Si aluminum alloy which has an outer wall 1a, an inner wall 1b and four radial joint walls 1c joining the former two walls. Rotary shafts 2 formed of Fe are made to project outward with respective one end fixed on the inner surface in each of the opposite ends of the inner wall 1b. The weight of this roll is about 1/3 of an iron one, and thus an operation of replacing the roll can be performed by one person. Moreover the cylinder is excellent in the adhesion to a copper plating layer and quite free from corrosion. The rotary shafts in a pair can be fitted simply to the cylinder.

Title: Humidifier
Inventor: SHISHIDO HIDEO
IPC: F24F6/02
Filed: 1993-05-18
Abstract: PURPOSE:To prevent adverse effects due to water scale by detecting water scale produced by concentration of calcium contained in water. CONSTITUTION:As water evaporates in an evaporating vessel 4, a calcium content in the water is concentrated. Since a high-concentration calcium water solution Wa is greater in specific gravity than water, it will collect on a bottom of a connection tube 13. As the surroundings are increased in specific gravity, a float 15 is increased in buoyancy to rise. When a magnet 17 integral with the float 15 is separated from a reed switch 16, the reed switch 16 is made off to suspend supplying of electricity to a heater 5.

Abstract: PURPOSE: To enable to vary the valve lift in a device for lifting the valve for an internal combustion engine and to obtain low noise and smooth transient characterristics thereof by operating the plunger of the device through a mechanism for amplifying the movement of the plunger.  
     CONSTITUTION: In case that the internal combustion engine speed is now low, namely, the opening area of an exhaust passage 20 to an oil pan is increased by a control valve 21 in response to the opening of a throttle or accelerator to reduce the oil pressure supplied through an oil feed hole 19 into second oil pressure chamber 17, when a piston 4 is retracted up upon rotation of a cam 6, the oil pressure in the first oil pressure chamber 12 rises to thereby start lifting a body 2 and accordingly a plunger 7. The lifting speeds of the body 2 and the plunger 7 depend upon the pressure receiving areas S7 and S2 of the plunger 7 and the body 2, respectively and springs 14 and 18. While the body 2 is lifting, the relative speed between the body 2 and the plunger 7 is small with the result that the plunger 7 will lift substantially the same speed as that of the piston 4

Title: System for calculating call rate
Inventor: SHIMAZAKI TOSHIYUKI
IPC: H04M15/34
Filed: 1988-05-11
Abstract: PURPOSE:To easily know the saving condition of a call rate by accumulating the difference of the call rate between the route of the dial number of an extension subscriber and a route which an optimum route selecting function has selected. CONSTITUTION:A private exchange 3 selects the optimum route based on the dial number 2 which the extension subscriber 1 has dialled at the time of originating a main wire, and transmits to the side of the main wire the dial number 2 to which a number is newly added, or from which the number is deleted, or which is not converted as it is as the selection number 7 of a called subscriber. Call rate calculation parts 11 and 13 by the dial number 2 and the selection number 7 cause call rate calculated value storage parts 12 and 14 to store respectively calculated rates. A comparison operation part 15 operates the difference, which is stored in a difference result storage part 16, and compares the size of respective stored contents. When the stored content of the storage part 12 is larger, the difference is accumulated in a call rate accumulation part 18. When the stored content of the storage part 14 is larger, the difference is accumulated in a call rate accumulation part 17. Thus, the saving condition of the call rate can easily be detected.

Abstract: The entrance to a fan duct of a gas turbine engine is provided with a plurality of circumferentially spaced projections or barriers extending radially inwardly from the wall of the duct. Each barrier is formed of a sound absorbing material, for example a honeycomb material covered with a resistive face sheet consistent with sound absorption. Each barrier has a varying circumferential width configuration wherein the greatest width abuts the duct wall and the width tapers to a minimum near the radially inwardmost point. The number and circumferential spacing of the barriers can be varied according to optimization of individual engine situations. The axial disposition of the barriers is such that the fluid wakes created thereby are substantially attenuated before interference with the fan blade.
