Title: Evaporation type combustion device
Inventor: ASANO YOSHIO
IPC: F23N5/24
Filed: 1983-11-25
Abstract: PURPOSE:To reduce odor or a production of incomplete combustion gas by a method wherein a heater is fixed near fuel reservoir arranged at fuel supplying nozzle, an energization of the heater is terminated simultaneously with diminishing of flame, the nozzle is cooled by the combustion blower to prevent the post dropping of the fuel toward an evaporating part. CONSTITUTION:When a flame is diminished, the combustion air blower 30 and the hot air blower 40 are energized through a temperature switch 37, so that the energized condition is kept unit the temperature of the temperature switch 37 is decreased. In turn, the fuels at a nozzle part 25 and within a oil reservoir 28 are heated by the sheath heater during combustion, the energization for the sheath heater 29 is terminated in simultaneous with the diminishing of the ignited fuel and the heating is terminated. Therefore, the fuel in the nozzle 25 is rapidly cooled. Due to this fact, the fuel is set to its more compressed condition compared with that of the combustion, resulting in that the fuel stopped at the extremity end of the nozzle 25 is suctioned toward the oil reservoir 28 and thus it is possible to prevent the post dropping of the fuel toward an evaporating part 27 from the nozzle 25 after the diminishing of the flame.

Title: Release mechanism for clutch
Inventor: KUSUMOTO HIROTAKA
IPC: F16D23/14
Filed: 1984-10-22
Abstract: PURPOSE:To enable smooth and reliable automation of centering, by a method wherein centering is automatically completed by rolling, and a work amount required for centering is extremely decreased by rolling friction factor. CONSTITUTION:When a point A of contact is moved to an ideal conical surface and centering is completed, a wheel 15 on the rotation side is rotated along the ideal conical surface during rotation of a diaphragm spring 6, slide contact surfaces of two members are brought into surface contact with each other and are limited by slip friction. Meanwhile, the end surface of a wheel 16 on the stationary side is also limited by slip friction. The ideal conical surface is always changed occasioned by wear of a clutch disc and wear of the contact part between the diaphragm spring 6 and a rolling bearing. But, resistance produced during centering action of a bearing is extremely low, centering is effected so that the point of contact is positioned to a current ideal conical surface, and this enables smooth automation of centering.

Title: Predicting device for heat accumulation of thermal head
Inventor: NAKA TOSHIYA
IPC: B41J2/36
Filed: 1988-09-08
Abstract: PURPOSE:To prevent density displacement under the transient state of a large temperature change by changing over thermal time constants in each cooling constant according to the magnitude of the temperature change and conducting heat-accumulation estimation being close to the observed values of the temperature change to each heating element and having high accuracy. CONSTITUTION:When a changeover-position detecting means 3 detects the position of the changeover of the constant of estimated-temperature arithmetic operation on the basis of the input of a data for recording, the means 3 transmits a changeover signal to a cooling-constant generating means 2. When there is the changeover signal, the cooling-constant generating means 2 transmits the cooling constant exp (-t/tau2) of a novel thermal time constant tau2 to a predicting-temperature arithmetic means 1 in place of the cooling constant of a thermal time constant tau1. Consequently, the thermal time constant included in the cooling constant sent to the estimated-temperature arithmetic means 1 is changed over, thus reducing the difference of a temperature observed value and an estimated one. Accordingly, a number of the thermal time constants are prepared, and compensated, thus eliminating density variation under a transient state.

Abstract: PURPOSE:To make it possible to obtain a magnet for generating a magnetic field which is satisfactorily uniform and has a low intensity, at a low cost by applying a dynamic field so as to stepwise change the magnetic field during repetition of measuring sequence. CONSTITUTION:Only during a certain time, a dynamic field power source 22 is energized so as to allow a dynamic magnetic field coil 21 to instantly increase the magnetic field strength to a magnetic field H1, so as to increase the magnetization M. Thereafter, the power source 22 is cut off so as to deenergize the coil 21 just before measurement of sequence. Then, the magnetic field strength H returns to a weak magnetic field strength H0 so as to establish a uniform magnetic field space. Thereafter, with the period of this uniform magnetic field space, a high frequency magnetic field at a specific frequency is applied to a body 1 to be detected, by means of a high frequency coil 14a, and then an inclined magnetic field in three axial directions are applied to the body 1 by means of an inclined magnetic field coil 9 so as to measure a signal. At this time that is intermediate of a period t0 during which the magnetization M increased during a certain time is decreased by its certain time constant even after the coil 21 is deenergized, thereby it is possible to obtain an image having a satisfactory S/N ratio with an increased magnetization M.
