Title: Heat treatment for coiled metallic material
Inventor: MATSUMURA ICHIRO
IPC: F27D7/04
Filed: 1995-03-09
Abstract: PURPOSE: To uniformly heat-treat coiled metallic materials in a short time by reversing the turning direction of furnace atmospheric gas along the axis of the coiled metallic material, between the fore half treatment group and the back half treatment group. CONSTITUTION: Coiled metallic materials 71 to 75 are heat-treated in mutually communicating divided plural treatment chambers 41, 42, to 45. In the fore half treatment chambers 41, 42, 43, a furnace atmospheric gas is allowed to flow downward by means of fans 51, 52, 53 and the flow of the gas in the coil inside peripheral part of the metallic materials 71, 72, 73 is made downward, and the flow of the gas in the outside peripheral part is made upward. The flows of the gases are reversed in the back half treatment chambers 44, 45. The occurrence of violent mutual interference of gas flows and resultant inferior circulation is limited only to the part between the treatment chambers 43, 44, and respective inside peripheral parts and outside peripheral parts of the coiled metallic materials 71 to 75 can be uniformly heat-treated.  As to the turning direction of the gas along the circumference of the coil, when it is controlled so that it turns clockwise and counterclockwise alternately in the treatment chambers 41 to 45, mutual interference of the gas flows does not occur and heat treatment can be performed more uniformly.

Title: Optical mark for detection and detecting method for the mark
Inventor: NABESHIMA TOMIO
IPC: G06K7/12
Filed: 1994-03-25
Abstract: PURPOSE:To easily and accurately judge a change in a data detecting environment by forming a sufficiently long leading part continued before a data part by a fluorescent material. CONSTITUTION:When a mark 14 is irradiated with light, the fluorescent material of the leading part 20 is excited at first and fluorescence is generated. Since the length of the leading part 20 is set up sufficiently longer than the continued part of the data part 21, fluorescence is generated from the leading part 20 with sufficiently large intensity and in a stable state and the intensity corresponding to a detecting condition or an environment is obtained. Since the leading part 20 is continuously arranged on a position close to the scanning starting position of the data part 21, the intensity of fluorescence discharged from the data part 21 is also uniformly changed over the whole area. The intensity of fluorescence generated from the leading part 20 is detected at first and the intensity of fluorescence generated from the data part 21 is compared with the detection value to be a reference, so that the contents of a mark formed on the data part 21 can be judged.

Filed: 1978-06-30
Abstract: PURPOSE: To firmly secure magnetic materials and obtain the magnetic material roll having even magnetic force by coating powder form adhesive agents on a fixing shaft through electrostatic coating at the time of forming the magnetic brush of an electrophotographic copier.  
     CONSTITUTION: At the time of securing magnetic materials 5a, 5b to the grooves 2, 3 and plane 4 of a fixing shaft 1, powder adhesive agents such as of modified nylon are coated on the fixing shaft 1 by an electrostatic coater and are heated for a short time at 100 to 150°C. Next, the magnetic materials 5a, 5b are mounted and are tentatively fixed. These are then heated further for 5 minutes to 1 hour at 180 to 250°C to allow the adhesive agents to set. As a result, the adhesive agents are evenly coated and the problems such as production of a clearance between the magnetic materials 5a, 5b and shaft 1 are eliminated. In addition, waste of the adhesive agents may be saved and firm bonding is made possible.

Title: Impulse noise rejector
Inventor: KOUNO TOSHIHIKO
IPC: H03G3/34
Filed: 1980-06-13
Abstract: PURPOSE:To effectively reject impulse noises without much damage to an original  signal, by changing a cutoff frequency of a variable filter added with the original  signal in accordance with the duration time of the impulse noises. CONSTITUTION:A music signal having an impulse noise from an input terminal is applied to a voltage controlled type LPF filter 12 via signal delay circuit 11. On the other hand, the impulse noise component included in the said music signal is detected at a noise detecting circuit 13 and it is converted into a pulse width signal having a pulse width corresponding to the duration time at a pulse forming circuit 14. Further, this pulse width signal is converted into a DC voltage corresponding to the pulse width at a pulse width/voltage converting circuit 15 and applied to a control terminal of the said voltage variable type LPF filter 12. Thus, if the duration time of impulse noise is short, the cutoff frequency of the LPF filter 12 is higher and inversely, if the duration time of the impulse noise is longer, the cutoff frequency becomes lower.

Filed: 1989-03-29
Abstract: PURPOSE:To grasp a physical property having frequency dependency in detail and precisely by transmitting the ultrasonic waves of plural frequencies while a sample is moved, detecting the acoustic characteristic of the sample and displaying it as a color signal which is made based on three primary colors. CONSTITUTION:The sample S shaped in a plate state is horizontally placed and the ultrasonic waves of the three frequencies are transmitted from ultrasonic wave transmission parts 20a, 20b and 20c on an upper surface while horizontally moving the sample S by a driving device 1. When a point P comes under the respective transmission parts, signals received by receiving parts 21a, 21b and 21c are arithmetically processed by a transmitter-receiver 22. Then, they becomes an acoustic characteristic signal Ak or the like and they are inputted in an image memory 3. Besides, they are made to be the three primary colors by an arithmetic operation unit 4 and transmitted to a CRT as a driving signal Ib' or the like. As the result, color display with intensity corresponding to the acoustic characteristic is obtained on a display screen. Thus, a video forming device that the physical property of the sample can be precisely grasped by scanning the required area of the sample is obtained.

IPC: H04R25/02
Filed: 1988-03-31
Abstract: PURPOSE: To surely interrupt the power supply when the hearing aid is not in use by including a switch that responds to a state change during removal of the hearing aid or during mount of the hearing aid and that is placed at a location being exposed in the state change to an automatic switching means.  
     CONSTITUTION: A temperature sensing switch 9 is placed to a side wall 10 of a housing 1 so that the temperature sensing switch 9 is closely in contact with a head of the user when the hearing aid is mounted behind the external ear of the user. In the case that the user dismounts the hearing aid without the operation of a switch 8, since the heat supply from the skin of the user to the temperature sensing switch 9 is interrupted, the temperature of the temperature sensing switch 9 is decreased, and since the temperature reaches a switch response temperature or below at which a power supply 7 is disconnected from an amplifier 3, undesirable discharge from the power supply is prevented. The temperature of the temperature sensing switch 9 reaches the response temperature in a very short time as above, the switch 8 is not entirely in use and the on-off control device of the hearing aid is controlled by only the temperature sensing switch 9.

At the same time, a switching circuit 14a is simultaneously turned off. A kick pulse outputted from the circuit 22 is supplied to a reproducing stylus moving means 17 through an adder circuit 15 and amplifier 16. After a reproducing stylus 12 moves once, the moved quantity is compared with an aimed moving track number by the act of a code storage circuit 19 and comparator circuit 20 and the next pulse width is controlled, so that the reproducing stylus 12 can be moved for a moving quantity which is closer to an aimed point. Therefore, the moving time of the reproducing stylus 12 at the high-speed searching time can be shortened.
