Title: Salt-resistant ni-added carbon steel for absorption type cooling and warming machine for water
Inventor: TSUJIKAWA SHIGEO
IPC: C22C38/00
Filed: 1996-10-30
Abstract: PROBLEM TO BE SOLVED: To provide a carbon steel type material with excellent corrosion resistance and to enable its effective application to a component material for an absorption type cooling and warming machine for water by adding specific amounts of Ni to the carbon steel type material. SOLUTION: Ni is added by 5.5-20.0wt.%, desirably 7.0-18.0wt.%, more desirably 8.0-13.0wt.%, to a carbon steel for an absorption type cooling and warming machine for water to be operated by using an aqueous solution composition containing alkali halide. As the alkali-halide-containing aqueous solution composition, a water - lithium bromide type, water - lithium iodide type, water - lithium bromide - lithium - iodide type, and water - lithium bromide - lithiun iodide - lithium chloride type aqueous solution composition or an aqueous solution composition prepared by incorporating lithium nitrate into the aqueous solution composition of the above types can be cited. This Ni-containing carbon steel has excellent corrosion resistance and can sufficiently withstand use even in an actual machine.  Further, this material is inexpensive as compared with a stainless steel because it is a low alloy steel.

In this case, only one side surface of the band-like belt 10 is brought in contact with and sucked to the front surface of the permeable belt 14 and reliably conveyed. Moreover, since the band-like member 10 can be conveyed by being sucked on the surfaces on both sides of the vertically laid permeable belt 14, the conveying distance can be approximately doubled in comparison with the conventional conveyer belt making use of only upper surface. The conveying device can be miniaturized and installed in the small floor area.

IPC: H02P6/06
Filed: 1994-12-09
Abstract: PURPOSE: To detect the rotational position of a rotor with high accuracy even when the intensity of magnetization of the rotor widely varies and, at the same time, to stably operate the rotor by providing a feeder circuit in an IC. CONSTITUTION: The rotational position of the cylinder (rotor) of the drum motor of a VTR is detected by detecting a prescribed magnetic pole formed by magnetizing the outer periphery of the cylinder by means of a Hall element 16. A control circuit 15 is integrally formed with an IC package. A shunt regulator 20, a peak detecting circuit 22, etc., are provided in the circuit 15. The element 16 is fed with electricity through a current limiter resistor 19 and its terminal voltage is adjusted by means of the regulator 20. Since the terminal voltage of the element 16 is controlled by means of the regulator 20 so that the peak value of the detected output of the element 16 can become constant even when the intensity of magnetization of the rotor widely varies, the rotational position of the rotor can be detected with high accuracy.  In addition, since the loss of the regulator 20 becomes smaller on the high temperature side, an IC can be operated stably.

Abstract: PURPOSE:To carry out traction control effectively and swiftly responding to a condition of acceleration by operating a brake booster while communication between a master cylinder and a wheel cylinder is cut when stepping on an acceleration pedal is detected, and by interlocking them when slip tendency is detected. CONSTITUTION:When it is detected that an acceleration pedal is made to step on to a certain decree in a fixed period of time before it is judged that a driving wheel is in slip tendency, communication between a master cylinder 5 and wheel cylinders 41, 42 is cut. Namely, pressure release valves 50, 51 are turned OFF while control valves 45, 46 are ON, or channels of both hydraulic pressure systems 43, 44 and hydraulic pressure escape systems 47, 48 are closed. A brake booster is operated, and when the driving wheel is judged to be in slip tendency, the master cylinder 5 and the wheel cylinders 41, 42 are communicated to one another. Since the hydraulic pressure of the master cylinder 5 is increased, the wheel cylinder can be operated instantaneously.
