Title: Sterilizing treating method for membrane separation unit
Inventor: YABUSHITA TOSHIO
IPC: A47J19/00
Filed: 1979-03-27
Abstract: PURPOSE: To prevent effectively the multiplication of microorganism and the formation of slime on the outside surface of the separating tubes of a tubular membrane separating unit, by dropping or spraying a microbicide fluid on the outside surface of the separating tubes.  
     CONSTITUTION: Many separating tubes 1, 1 of a tubular membrane separating unit A are continued so as to form an exposed zigzag path with heads 2, 2 connected to both ends of the tubes. Alternate repetition of the treatment by dropping sterilizing fluid on the outside surfaces of the separating tubes from a perforated pipe 5 and the washing operation with washing water from nozzles 6, 6 for the outside surfaces of the separating tubes 1, 1 can be applied either during operation or during shut- down of the unit A. Hereby, the multiplication of microorganisms on the outside surface of the separating tubes is prevented. A little slime formed on the surface of the tubes, if any, is easily peelable, and is removed by the next spray of washing water.

Title: Method of rapid refrigeration control for electric refrigerator
Inventor: HOSHINO AKIHITO
IPC: F25D17/08
Filed: 1988-02-19
Abstract: PURPOSE:To enable the feed of cold air in a large quantity and at a high wind velocity and to permit faster refrigeration of food, by a method wherein through control of a rapid refrigeration button, a compressor, a damper, and a fan are motioned. CONSTITUTION:It is decided whether a rapid freezing button 5a of a control panel 5 is controlled. When no rapid refrigeration button 5a is controlled, normal processing is executed. When the control is effected, a built-in timer 4a is set, and counting of a given time is started. Further, a motor damper device 9 of a cold storage chamber and a motor damper device 10 of a vegetable chamber are brought into an OFF-state, and control to close respective dampers is executed. Control is executed to that a compressor 6 and a fan motor device 7 continuously maintain on ON-state, and a working frequency is increased. This operation causes the feed of cold air into the cold storage chamber in a larger quantity and at a higher wind velocity compared with a conventional rapid freezing method. Subsequently, when the rapid refrigeration button 5a is brought into an OFF-state, control of rapid refrigeration is rendered ineffective to start normal operation. When no control is executed and the built-in timer 4a is timed up, control of rapid refrigeration is rendered ineffective to start normal operation.

Title: Looseness indicator for spring washer
Inventor: UDAGAWA HIROSHI
IPC: F16B39/24
Filed: 1995-01-17
Abstract: PURPOSE: To provide a looseness indicator for spring washer which can facilitate the detection of a loose spring washer by mounting it onto the spring washer. CONSTITUTION: A base part 1 constituted of spring material is fixed onto the step-off part 14 of a spring washer 13. The base part is formed with a slantingly rising inclined part 2 integrally with it. The inclined part is formed with a protrusion part 3 standing outwards from the outer periphery side surface of the spring washer. As a result, the loose condition of the spring washer appears as the inclination of the protrusion part, and the protrusion comes out to the outside of the head part, of a screw, so it is possible to inspect the inclining condition of the protrusion part. The shifting condition of the end of the protrusion part is increased according to the length of the protrusion part, so it is possible to inspect the loose condition of the spring washer sensitively.  It is also possible to visually-inspect the loose condition of the spring washer without tightening the screw with a screw-driver.

Filed: 1998-02-05
Abstract: PROBLEM TO BE SOLVED: To discriminate easily between the rear and front of a wafer, to prevent a crown-like epitaxial growth film from being grown, and to protect an epitaxial growth layer effectively against contamination, by a method wherein a chamfered part is provided to a part of or all of the outer circumference of the rear of the wafer. SOLUTION: Only the outer circumference of the rear of a mirror-finish wafer is partly or fully chamfered. That is, only the rear edge of the wafer is chamfered after the wafer is subjected to final finishing polishing, and the front of the wafer where an epitaxial growth layer is grown is not chamfered. By this setup, the rear and front of the wafer can be easily discriminated from each other by detecting a chamfered part. The rear edge of the wafer may be either partly or fully chamfered. The front of the wafer where an epitaxial layer is grown is not chamfered, so that the epitaxial layer is restrained from growing abnormally in a specific direction on the outer circumference of the wafer and protected against contamination at melt-back.
