Patent JP-H05139141-A (JP)
Title: Air conditioner
Inventor: KAJINO YUICHI
IPC: B60H1/00
Filed: 1991-11-22
Abstract: PURPOSE:To quickly change ventilating temperature in conformation to an environmental change without an excessive temperature change and provide a stable operation and a certain target temperature. CONSTITUTION:The temperature change of a target blowoff temperature is detected. When the temperature change is smaller than a standard temperature difference, an air mix damper 6 is controlled by the feedback control based on the deviation between the blowoff temperature detected by a blowoff temperature sensor 16 and the target blowoff temperature, and when the temperature change is larger than the standard temperature difference, the air mix damper 6 is driven according to the moving quantity corresponding to the temperature change. Even if the target blowoff temperature is largely changed, the temperature of the blown air can be quickly changed, and thereafter, it can be certainly approached to the target blowoff temperature.

Title: Thin-film type thermal head and its manufacture
Inventor: SATONAKA TAKAMI
IPC: B41J2/335
Filed: 1988-12-06
Abstract: PURPOSE:To obtain a protecting film having good abrasion resistance and heat conductivity by forming an abrasion-resistant layer in two-layered structure of SiOxNy for a flower layer and SiCz for an upper layer (x,y and z represent the ratio of a component, x=0, y=0 and z=0). CONSTITUTION:An SiOxNy film 5 as a lower layer is formed through plasma CVD process using SiH4, N2, N2O and O2 as material gases. If NH3 is contained in the material gas, the containing amount of hydrogen in the film is increased. Therefore, from the viewpoint of heat-proof property, it is preferable that the material gas contains little NH3. It is necessary to throw-in a large quantity of electric power to dissolve the N2. An upper layer 6 is formed of SiCz through plasma CVD process using SiH4, CH4, C2H4 and C2H2. A gas containing less CH group in CH4, C2H4 and C2H2 is more desirable from the viewpoint of heat-proof property. The temperature of a substrate should be 300 deg.C or higher. Even when N2O or O2 is not added, if a large quantity of power is thrown-in, nitrogen ions or radicals of high exciting property are produced. Accordingly, the hydrogen in the film can be reduced by the hydrogen separation reaction between the nitrogen ions or radicals and Si-Hn. As a result, a protecting film having good abrasion resistance and thermal conductivity is obtained.

Title: Method and apparatus for controlling compression molding machine
Inventor: HONJO YUTAKA
IPC: B29C43/02
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To avoid an obstruction of degassing upon compression molding, a bulge of a molding or a change in a flash by starting preheating of a material when a die is pressurized and compressed so that a die interval becomes a given value or an applied pressure is raised to a given value. SOLUTION: A preheating starting position setter 22 and a preheating starting pressure setter 24 are suitably set and regulated so that a pressure of a cylinder 7 arrives at a preheating starting pressure before a movable board 5 arrives at a preheating starting position. When the board 5 approaches a fixed board 4 so that a material in a cavity of a movable die 2 is pressurized and compressed by a core by a fixed die 1, an oil pressure in a pressurizing chamber of the cylinder 7 is raised as its reaction force. When the pressure arrives at the preheating starting pressure, a compression and movement signal of the board 5 is switched to hold its position, and continued until next compressing step is started. The compressing step is previously programmed together with a degassing step and a repressurizing step.  Thus, molding without influence of an amount of the material supplied to the die or an unevenness of a curing speed is performed, and a defective ratio of the molding can be reduced.

Abstract: PURPOSE: To reduce a width changing part for cast slab and to improve the yield by making the width changing time the shortest regardless of the size of the width changing, in the width changing method with a mold for cast slab. CONSTITUTION: At the time of enlarging or shrinking the cast slab width by shifting the short side of the mold, the shift of the short side is divided into a front inclining period gradually inclined to the center side of the mold and a rear inclining period gradually inclined to the reverse center side of the mold and an accelerating ratio (α) of the shifting velocity in the horizontal direction of the upper and the lower end parts of the short side in each period is beforehand obtd. by using a permissible shell deformed resistant force as a parameter.  Further, the difference ΔV between the shifting velocities at the upper and the lower end parts is decided with the equation ΔV=α.L/Uc (wherein, L is the length of the short side of the mold and U is casting velocity), and the accelerating ratio and the velocity difference are kept to the constant to execute the width change. Just after starting the width change, the shifting velocity at the lower end part of the short side is made to be zero so that the average value with time in the shifting velocity Vu0 at the upper end part is equalized with ΔV or more velocity. Further, just before completing the width change, the shifting velocity at the upper end part of the short side is made to be zero so that the average value with time in the shifting velicity Vl0 at the lower end part is equalized with ΔV or more velocity to execute the width change.

Wire from the front of the resistor 14a is connected to the electrodes 11a, 11c of an electrostatic Q-lens and wire from the rear of the resistor 14b is connected to the electrodes 11b, 11d of the electrostatic Q-lens. The point of connection between the resistors 14a, 14b is grounded. The resistance values of the resistors 14a, 14b are ideally the same and selected so that the voltages generated can correct, by means of the chromatic aberrations of the electrostatic Q-lens, chromatic aberrations occurring at the electromagnetic Q-lens.
