Abstract: PURPOSE: To enable effecting preliminary sterilization of the inside of an aseptic filling chamber with saturated steam properly by filling a joint of the wall with packing and closing a stopper-inserting hole by a stopper-sterilizing chamber in a manner of hermetically closing an aseptic filling chamber. CONSTITUTION: An aseptic filling chamber 1 is hermetically closed by filling the joints of the sides 2 of the chamber with packing 3, closing a stopper- insertion hole 5 by a stopper-sterilizing cup 6, and closing a steam-discharging pipe 8. Next the aseptic filling chamber 1 is filled with sterilizing steam through a steam-feeding pipe 7.

Title: Fan-starting force controller
Inventor: MAEDA SHIGENOBU
IPC: F04D27/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To reliably start a fan and suppress noises emitted at its normal operation by controlling the fan at its starting so as to be supplied with a higher voltage until its stable rotation and with a lower voltage thereafter. SOLUTION: Upon the starting of a fan 3 serving to forcibly emit heat for preventing a failure in the equipment due to its temperature rise, a transistor control circuit 13 outputs H-signals during the charging of a capacitor 7 to turn a transistor 9 on. A transistor 4 is thereby turned on to supply a direct current 1 to the fan 3. When the charging voltage to the capacitor 7 reaches a threshold value of input voltage to a Schmitt-trigger input inverter 8, L-signals are outputted to turn the transistor off. A capacitor 12 is thereby charged up to turn the transistor 4 off, which then supplies a lower voltage to the fan 3 to lower the rotating speed thereof.

Title: Control method of air conditioning apparatus
Inventor: NAKAMURA TAKAAKI
IPC: F24F11/04
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To readily return a room temperature to an original condition when the room temperature greatly fluctuates from the steady condition, wherein such a fluctuation of room temperature occurs when a door or a window is opened to make an outdoor air enter a room during a save-mode operation which regulates the room temperature by restricting the operation frequency of a compressor and an air amount of an indoor fan. SOLUTION: When a room temperature Tr exceeds a predetermined temperature range (for example, a predetermined temperature ±1 deg.C) by a desired temperature (for example, 1 deg.C) due to an entrance of outdoor air or the like during the save-mode operation, the save-mode operation is interrupted for a predetermined period. During this period, an air conditioning apparatus is operated under a normal operation where the restriction on the operating frequency of a compressor and an air amount of an indoor fan is released so that the room temperature which has been greatly fluctuated from the steady condition is readily returned to an original condition.

Title: Protector for underground burried structure
Inventor: TSUZUKI TAKESHI
IPC: C23C30/00
Filed: 1996-06-20
Abstract: PROBLEM TO BE SOLVED: To surely detect existence of a protector when a cutter contacts the protector to thereby prevent cutting or damage of a burried structure protected by the protector by forming the protector covered with a cutter function decreasing material on its hard steel surface downward curvedly in the advance direction of the cutter. SOLUTION: When a protector 6 having a high hard steel 7 covered with a cutter function decreasing material 8 composed of the low hard steel, resin, rubber and the like is brought into contact with an advancing cutter, the low hard steel 8 is made to stick to the diamond at an end of cutting edge. In this case, the protector 6 is formed at its opposed ends downward curvedly 10 so that it faces downward to the advance direction of the cutter when it is positioned above a burried structure. Accordingly the material 8 is liable to stick to the cutter to thereby decrease the function of the cutter, thereby cutting no high hard steel 7, resulting in prevention of cutting and damage of the burried structure.

Title: Multimode optical fiber
Inventor: MURAKAMI TAIJI
IPC: G02B6/036
Filed: 1982-09-14
Abstract: PURPOSE:To decrease the loss right after drawing and the loss after cabling and owing to deterioration with the lapse of time by making a deposited clad layer thick to maintain the concn. of the OH group at the boundary between a core and a clad at a specific value or below. CONSTITUTION:A quartz multimode optical fiber is constructed of a core glass part 1, a deposited clad layer 2 and a molten quartz tube 3. The OH group from the tube 3 diffuses when the tube 3 is exposed to a high temp. of >=1,200 deg.C such as in the stage manufacturing a small diameter fiber by drawing from a preform or during the glass deposition when the core part and the layer 2 are deposited internally by MCVD on the inside of said tube. The reason for such diffusion lies in that the coefft. of diffusion of the OH group increases with an increase in the temp. The OH group which is the main factor for the loss on a higher mode side is reduced in order to decrease the increase in the loss occurring in cabling and deterioration with age. The thickness of the layer 2 is made <=7mum in order to maintain the concn. distribution of the OH group at the boundary with the clad layer 2 at <=0.1ppm to prevent the diffusion of the OH group particularly to the core part 1.
