Abstract: PURPOSE: To perfectly interrupt energizing with respect to a heater and to transmit the occurrence of abnormality and failure of a fixing device by turning off the power supply of the heater in a state where a switching means engaged with a fixing roller bearing is in an off-condition. CONSTITUTION: The switching means 13 is constituted of a switch arm 14 and a switch 15. One end side of the arm 14 is engaged with the external circumference of the fixing roller 1 shaft, and the other end side abuts on the switch button 15a of the switch 15. When abnormality occurs in a thermistor 3, so that the fixing roller 1 is abnormally heated by the heater 4 and a fixing roller bearing 5 supporting the fixing roller 1 starts melting by a high temperature, and the roller 1 is pushed upward by the pressure of a pressuring spring 9 pressuring a pressuring roller 2. The external circumference of the roller 1 pushes one end side of the arm 14 upward while having a supporting shaft 14a as the fulcrum, and the other end side pushes the button 15 downward so as to turn the switch 15 off. Thus, the power supply for the heater 4 is interrupted.

IPC: G11B5/455
Filed: 1989-05-17
Abstract: PURPOSE:To improve the quality of a magnetic tape head and to eliminate the loss of cost by, for a core, inspecting the polarity of a core winding before it is sealed in a housing. CONSTITUTION:A reference magnetic tape head 5a, in which the polarity of the core winding is already known, is excited in a fixed direction by a DC power source 8a, and a measured magnetic tape head 5b, in which the polarity of the core winding is unknown, is opposed to the reference magnetic tape head 5a by mutually facing the head gap parts.

Title: Method and device for determining flaw in subject for examination
Inventor: OZAWA KINGO
IPC: G01B17/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To judge with high reliability the severity of a flaw in a subject for examination, such as a railroad rail, by performing appropriate evaluation that matches the kind of the flaw. SOLUTION: Ultrasonic pulses are radiated to a rail 10 through a multichannel ultrasonic wave transmitting/receiving part 12 through an ultrasonic probe 11, and a reflected echo at each of plural channels is detected by a reflected echo detecting part 13. A connection area of the detected reflected echoes on a B-scope image is extracted by a connection area extracting part 14. Magnitude and end-point position on the B-scope image, the central value of the input signal level of the reflected echoes constituting the connection area, and the central value of the beam path of the reflected echoes are calculated by a feature amount extracting part 15 as the feature amounts of the connection area, and the kind of a flaw is identified by a flaw-kind identifying part 16 from the kind of the channel and the central value of the beam path of the reflected echoes extracted.  The severity of the flaw is judged by a severity judging part 17 on the basis of the kind of the flaw, the magnitude and end-point position of the connection area on the B-scope image, and the central value of the input signal level of the reflected echoes.

Title: Anti-skid unit
Inventor: AKAKABE YOSHIFUMI
IPC: B60T8/42
Filed: 1981-08-07
Abstract: PURPOSE:To prevent braking force from being excessively released upon running on frozen road surface, by energizing a brake release signal for a time period corresponding to braking pressure. CONSTITUTION:An arithmetic circuit 44 produces a release signal Y in association with the speeds of wheels 18, 19. A pressure gauge 42 converts pressure in a pipe line 17 into electrical voltage, and a memory 43 delivers the release signal Y to a converter 45 when the signal Y is generated. The converter 45 delivers a time period dependent upon pressure for operating a solenoid valve 52 through an AND circuit 46, an OR circuit 47 and an amplifier 51. When the time period of the release signal is longer than the output of the converter 45, a NOT circuit 48 and an AND circuit 49 operate a pulse generating circuit 50 so that a servo- piston stops its retracting movement and braking pressure repeatedly varies bit by bit. Even if an excessively long release signal is produced, the plunger 22 never retracts largely than it is needed, thereby the excessive release of the brake is prevented.

Title: Lost foam pattern casting method
Inventor: OKUJIMA YOSHIKATSU
IPC: B22C7/02
Filed: 1992-05-18
Abstract: PURPOSE:To form a hollow part having complicate shape even in the case of casting into a lost foam pattern by supporting the end part of a metallic pipe forming a hollow part shape in a finish product with this inner surface by non-bonding sand. CONSTITUTION:The end part 12a of the metallic pipe 12 forming the necessary shape in the finish product with the inner surface is projected from a foam forming body 13 and supported by the non-bonding sand 28. At the time of pouring molten metal into a sprue 24, a runner 25 and pattern 22 made of the foam forming material are thermally decomposed and lost to fill up the molten metal. As the non-bonding sand 28 is filled up in the metallic pipe 12, the metallic pipe 12 can form the hollow part at the accurate position without breaking and deforming.

Title: Method of attaching synthetic resin plate to metal plate
Inventor: YAMAMOTO TERUO
IPC: F16B5/02
Filed: 1981-08-07
Abstract: PURPOSE:To prevent a screw stock from breaking while being driven, by using a nut having a protuberance at the lower part, in case when a resin plate put on the surface of a metal plate is secured by driving a nut on a screw stock that stands on the metal plate and is located in an attaching opening of the resin plate. CONSTITUTION:In case that the synthetic resin plate 2 having the attaching opening 4 is placed on the metal plate 1, one end of the screw stud 5 having a constriction 6 is secured to the metal plate 1 by stud welding such that it extends in an approximately upright state through the attaching opening 4, the nut 9 is driven on the screw stud 5 to be buried in a large diameter hole 3 provided to the attaching opening 4, and then part of the screw stud 5 projecting from the nut 9 is bent at the constriction 6 and is removed, so that the resin plate 2 is attached to the metal plate 1, the nut 9 should include at the lower part the protuberance 8 having a diameter equal to or slightly smaller than that of the attaching opening 4. Thus if the nut is driven with the screw stud 5  biased from the upright position, the screw stud 5 is prevented from breaking at  the constriction 6 if the end part of the nut 9 abuts on part other than the large diameter part 3 and a locally exerted force is applied on the nut 9.

Abstract: PURPOSE:To perform operation of an information processing equipment and relative operation in parallel by holding the image display device, which consists of a magnifying reflecting mirror made of a transparent material enlarging and reflecting a small screen where transmission information from the information processing equipment is displayed, at a human body position which is at a constant relative distance to the eye in front of the eye of the user. CONSTITUTION:A lead line 8 from an information processing equipment main body 1 extends to a wearing tool 3 and then reaches the small screen 5 by penetrating the tool and the transmission information from the information processing equipment main body 1 is projected on the small screen 5. The transmission information from the information processing equipment main body 1 which is projected on the small screen 5 is reflected by a wide-angle reflecting mirror 6 through a path shown by an arrow and further reflected by the internal surface of the magnifying reflecting mirror 7 to reach the eye of the wearing person. The wearing person sees the transmission information as a virtual image 10 which is enlarged large in front of the person. The magnifying reflecting mirror 7 is transparent, so a body which is placed in front of the eye, i.e. beyond the magnifying reflecting mirror can be seen at the same time. Consequently, the information processing equipment is operated to perform other desk work while referring to the transmission information.
