Title: Reel device for cable
Inventor: KAWAMOTO AKIO
IPC: B60R16/027
Filed: 1994-12-28
Abstract: PURPOSE: To smoothen the movement of a flat cable and the rotation of a spacer by forming a cable pressing part on a cable guide part excluding the vicinity of a reversing insert part. CONSTITUTION: The cable guide part 111 of a guide body has a cable pressing part 112 opposed to the other side part of a cable to arrest the separation of the cable from a groove part 55, which is provided excluding a reversing insert part 106 or its vicinity. Thus, when the cable is rewound in the inside of the groove part 55, passed through the reversing insert part 106 of the guide body while it is reversed in U-shape, and delivered to the outside of the guide body, only the cable in the reversing insert part 106 or its vicinity is separated from the groove part 55 to the outer circumferential side, and the other part of the cable is laid in the state held by a groove part provided on a shaft part.  It is only in the reversing insert part 106 or its vicinity that the cable is slid to the guide body, and the frictional resistance between the cable and the guide body is reduced to smoothly deliver the cable.

Abstract: PROBLEM TO BE SOLVED: To improve yield and also to prevent buckling by suppressing variation in width between materials to be rolled and in the material itself to be rolled, reducing margin allowance by changing the target value of width based on the rolling temp. of the material to be rolled. SOLUTION: In tha case of high rolling temp., the amount of width return at the final horizontal rolling mill R3 changes from dW0 in the case that the rolling temp. is as set to dW1. Taking the target value WR of width on the outlet side of a roughing mill group as a reference and, as taking the edging amount dWE with an edger E3 as constant, the target value of width on the outlet side of the horizontal rolling mill R2 which is the inlet side of an edger E3 before the horizontal rolling mill is changed from WH0 to WH1. In such a case, the preset value of the opening degree of the edger is changed from WH0-dWE to WH1-dWE. Next, also about the opening degree of the edger E2 of the next on the upstream side, similarly WH1 is calculated as the new target value of width after horizontal rolling. By repeatedly executing this operation about each pass, the target value of width is set and simultaneously the opening degree of the edger is set.

Filed: 1995-11-24
Abstract: PROBLEM TO BE SOLVED: To reduce a minute crack to take place in a piezoelectric bimorph and also to improve working efficiency by arranging a strain gauge for detecting a displacement amt. of the piezoelectric bimorph on an elastic supporting member. SOLUTION: A head base 13 is supported by the piezoelectric bimorph 14 and the elastic supporting member 15. When a driving voltage is impressed upon the bimorph 14, and the bimorph 14 is curved to be displaced, the supporting member is also curved, while tracking operation is performed by a head chip 12. Resistance values of the strain gauges 22 and 23 stuck to the front and back surfaces of the supporting member 15 are changed to increase on the expanding side of the supporting member 15 as against the state of its repose and to decrease on the contracting side as against its repose respectively. Consequently, by detecting a difference between the resistance values of the gauges 22 and 23, the replacement amt. of the bimorph 14 can be observed.  As a result, while auto-tracking operation of the magnetic head device is held as it is, the occurrence of a minute crack in the bimorph 14 can be reduced.

Title: Four-way valve for refrigerating cycle
Inventor: FUJIMOTO RYUZO
IPC: F16K31/66
Filed: 1987-12-25
Abstract: PURPOSE:To achieve high reliability at low cost with a simple structure with less number of component parts by providing a heat-responsive device disposed so as to exchange heat with the ambient air, and a valve unit to work in conjunction with the heat-responsive device, and comprising the heat-responsive device with a superconducting material with a magnetic substance being disposed to one surface and of the heat-responsive device. CONSTITUTION:A bellows 34 is disposed at one end of a four-way valve 33. One end of a heat-responsive device 37 is fixedly attached to the end of the bellows 34, and the other end 39 of it is opposed to a magnetic substance 38 one end of which is fixedly held by a holder 35. When cooled with the heat-responsive device 37 and the magnetic substance 38 contacting each other, the heat-responsive device 38 comprising a superconducting material overcomes the force of the bellows 34 by the effect of superconductivity at a temperature lower than a certain level, and lift itself off the magnetic substance 38 to move to the left until it is stopped. When the cooling is suspended and the temperature is allowed to rise, the effect of superconductivity is lost, and the heat-responsive device is pushed to the right back to the initial position by means of the force of the bellows. Since the interior of the four-way valve is under the same refrigerant pressure and its function is not affected by the difference between the high and low refrigerant pressures, a highly stable reliability can be obtained.
