Title: Fluid heater
Inventor: SHIMODA YUTAKA
IPC: F24H1/10
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the retention part of fluid from being formed in the fluid heater of a quartz double pipe structure. SOLUTION: Three pipe bodies 17 and 21 made of quartz glass are inserted into the cylindrical tubular part 10 of a tubular body A1 made of quartz glass. Into these pipe bodies respectively, halogen lamps are inserted. To the tubular body A1, an inlet pipe 15a having a fluid inlet port 15 and an outlet pipe 16a having a fluid outlet port 16 are attached. In this case, the inlet pipe 15a is attached in an inclined manner so as to intersect the axial direction of the tubular body A1. Thus, fluid entering through the inlet pipe 15a rotates and flows along the inner wall of the tubular part 10 of the tubular body A1, so that it is not retained.

Filed: 1995-02-16
Abstract: PURPOSE: To surely establish communication by sending a special tone when the facsimile equipment decides that a destination equipment having been registered and making a call has a short protocol function and updating the registration based on the presence/absence of a reply with the tone after conducting communication/line interrupting in the short protocol mode. CONSTITUTION: An MPU 14 controls read, recording scanning section and processing sections 20, 22, 24 or the like to read registration data of the opposite party in a RAM 18 thereby checking the availability of a short protocol function of the opposite party. When the function is available, a special to one signal S commanding the transit to the short protocol mode is sent and the presence of a reply from the opposite party with respect to the signal S is decided. As a result, when no reply is received, it is decided that a model of the opposite party is changed into a model unable to reply the signal S, the line is interrupted an registration data of the opposite party are updated from the presence to the absence of the short protocol function.  On the other hand, when the reply is received, after the presence of the short protocol function is confirmed, data are sent by the short protocol mode, and when not confirmed, communication is made by a standard protocol mode. Thus, even when models are changed, sure communication is attained.

Abstract: PURPOSE: To eliminate troublesome operations, and make highly accurate measurement by detecting the height of a measured area, and thereby correcting the blood pressure or a blood vessel condition measured by a measuring means in response to the height at which measurement has been made. CONSTITUTION: When a start switch 7 is turned on, the inclination θ1 of a main body 11 is detected by an inclination sensor 8, it is taken in a MPU 3 through an A/D converter 2, and it is stored in a memory 9. After that, a wrist is pressed by a cuff, its pressure is increased up to a specified cuff pressure, and it is then decompressed thereafter. In the process of a series of pressing and decompressing, the maximum and the lowest blood pressure are determined based on string data for the amplitude of a pulsation wave to be detected by a pulsation wave sensor 1 and cuff pressure. After the decision of blood pressure has been over, the inclination of θ2 of the main body 11 is measured again, and the inclination θ2 measured at this point is stored in the memory 9.  Next, the difference H in height is computed based on the inclinations θ1 and θ2 and if the difference is in a specified range, a correction value is then computed so as to allow a blood pressure value to be corrected, and the corrected blood pressure value is then indicated on a display unit 4.

Abstract: PURPOSE:To enable positioning control with a high speed and high accuracy, by using a position detecting sensor for an object to be positioned to get rid of the unstability elements such as the vibrations due to a spring, etc. which is used to absorb the impact of collision. CONSTITUTION:It is decided that an object 2 to be controlled is pressed to a mobile part 1a when the moving speed of the object 2 which is calculated via a signal S is lower than the reference level. Thus control is started (t0). In this case, the position of the contact face between the object 2 and the part 1a is set at A0. At the same time, the extent of shift of the position A0 is defined as L0 to the reference position. Then the control degree C0 corresponding to a shift between the present position L0 and the target position LA at a time point t0 is fed to a positioning actuator 1. Then the contact face is moved to the position A1 from the position A0, and the control degree corresponding to deviations (L1-LA) remaining at the point t1 is added to the previous control degree C0 to obtain a new control degree C1. Furthermore the contact face is set close to the position LA. Thus the control compoletes when the position Ln gets within a ragne LA+ or -epsilon.
