Title: Operation inspection device for opening/closing means
Inventor: ITO KENJI
IPC: G01M3/04
Filed: 1995-12-18
Abstract: PROBLEM TO BE SOLVED: To inspect the operation of an opening/closing valve without a high pressure air source. SOLUTION: A ball 32 is pressed to a ball engaging surface 40 of a valve seat 30 by a spring 34 to form a check valve 14. The ball 32 is pressed in the direction of opening the check valve 14 by the energizing member 60 of an energizing part 18. The pressure of air supplied from an air source 20 is applied to the ball 32 through an inlet passage 38. Accordingly, the sum of the energizing force of the energizing member 60 and the air pressure supplied from the air source 20 is applied to the ball 32. Accordingly, the pressure over the valve opening pressure can be applied to the check valve 14. It is detected from the presence of generation of air bubbles from the forward end of an outlet passage 44 submerged in a water tank 22 whether the check valve 14 is in the open state or not.

Inventor: TAKAHASHI NOBUHARU
IPC: A01N25/06
Filed: 1988-12-26
Abstract: PURPOSE:To obtain the title composition which, when sprayed in large quantities, scarcely tends to be highly flammable and can retain the diffusivity in spite of a reduction in the fluorochlorohydrocarbon content by mixing a kerosene-base stock oil with a propellant consisting of a fluorochlorohydrocarbon, a combustible liquefied gas, and CO2.

When sprayed in large quantities, this composition scarcely tends to be highly flammable and can retain the diffusivity although the fluorochlorohydrocarbon content is relatively low; therefore, it is suitable for use in a limited space, e. g. under the floor, in the ceiling, or in a room. The reduction of the usage of fluorochlorohydrocarbons is desirable also from the viewpoint of maintaining the natural environment.

Title: Switching regulator
Inventor: UMETSU FUMIKAZU
IPC: H02M3/338
Filed: 1987-12-26
Abstract: PURPOSE:To operate safely and to apply a protection against overheat with a simple constitution by using a posistor as a starting resistor and a base current limiting resistor. CONSTITUTION:A switching regulator is such that input power supply applies starting voltage to the base of a switching power transistor(Tr) Q1 through starting resistor P1, and that the Tr Q1 is turned ON. When Tr Q1 is turned ON, the oscillation is started due to positive feedback operation by an oscillation base winding L3 wound on a transformer T1, a diode D1, a capacitor C1, base current limiting resistor P2 and so on, and the Tr Q1 is accordingly turned ON/OFF. At that time, a posistor is used for the starting resistor P1 and the base current limiting resistance P2. Accordingly, when a temperature rises, a resistance also rises, so that the increase in collector current of a Tr Q2 is reduced, the Tr Q1 is controlled under a stable condition, and the loss of power can be reduced.

Abstract: PURPOSE: To enable the picture of an interrupted operation to be reproduced instantaneously by a method wherein a console is temporarily interrupted in operation on a picture of lower hierarchy and transferred to a picture of higher hierarchy jumping over a picture of intermediate hierarchy for another operation or reversely returned to a picture of lower hierarchy from a picture of higher hierarchy jumping over a picture of intermediate hierarchy for another operation. CONSTITUTION: When an operation carried on a picture of lower hierarclny is temporarily interrupted for another operation, a control button is pushed down for inputting operational parameters into a console CPU 331. The console CPU 331 temporarily interrupts an editing operation in accordance with the inputted operational parameters, is transferred to a picture of higher hierarchy jumping over a picture of intermediate hierarchy for another operation, and indicates the picture on a display 102 keeping an operating state at this point. After another operation is finished, a button is so operated as to return an indication on the display 102 to a picture of lower hierarchy from a picture of higher hierarchy jumping over a picture of intermediate hierarchy. Therefore, the picture of an interrupted operation is capable of being instantaneously reproduced.

IPC: B29L11/00
Filed: 1998-11-20
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a plastic optical fiber 20 capable of manufacturing the plastic optical fiber which is sufficiently low in transmission loss. SOLUTION: The process for producing the plastic optical fiber 20 consists of a stage for forming a core 12 by preparing a core rod and melt stretching part of the core rod. A clad material 18 held above Tg of the core 12 is extruded by an extrusion method and the core 12 is clad by the clad material 18, by which the plastic optical fiber 20 is obtained. In such a case, the temperature of the core 12 is maintained at above Tg when the core 12 is clad by the clad material 18. The internal strain of the core 12 is relieved and the surface is melted, by which the strain at the surface is relieved. The surface mismatching between the core 12 and the clad 19 is sufficiently prevented by the plastic optical fiber 20. Further, the core rod 1 is independently formed and, therefore, the diameter of the core rod is formable to an arbitrary size.
