Title: Warm air heater
Inventor: HORINAKA KIYOSHI
IPC: F24H3/04
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To provide a warm air heater having an air outlet structure for improving its safety. SOLUTION: A cover 19 for implanting a plurality of fiber members 20 is fixed to surfaces of louvers 15 provided in an air outlet 5 of the warm air heater 1. The member 20 and a foundation cloth 23 have lower thermal conductivity than that of the louver 15, and fibers having higher heat resistance than that of a highest temperature of warm air diffused from the outlet 5 are used. Thus, when a person is brought into contact with a surface of the louver 15, its contact area can be reduced, and heat is scarcely transferred to the member 20 itself, and hence safety of the outlet 5 can be improved.

Title: Superconducting magnet
Inventor: MITSUNE SUSUMU
IPC: H01F6/00
Filed: 1989-01-13
Abstract: PURPOSE:To suppress the deformation of a coil when power is applied by a method wherein between each coil presser is coupled with the groove, provided at the butted part of the coil pressor, and the coupling member fitted to the groove. CONSTITUTION:The coil pressers 2 of superconducting dipole coils 1, which are arranged on a concentric circle, are arranged in such a manner that one surface each of them are mutually butted, a groove having a horizontal U-shaped cross-section is provided astriding the adjacentcoil pressers 2 on the butted surface of the coil pressers 2, a coupling metal fitting 3 is fitted to the groove, and all the coil pressers 2 are fixed. By having the above-mentioned constitution, the deformation of the coil pressers 2 is suppressed because the butted part of the outer circumference of the coil pressers 2 is fixed by the coupling metal fitting 3 even when the coil pressers are subjected to deformation by the electromagnetic force of the coil 1. As a result, it is unnecessary to increase the size of the coil pressers in order to enhance their rigidity, and a superconducting magnet of small size and light weight having high reliability can be obtained.

Title: Brazing method
Inventor: ITAMI KUNIHIKO
IPC: B23K3/00
Filed: 1979-01-22
Abstract: PURPOSE: To let the brazed structure of high reliability be obtained by separating the inside of a  hermetic vessel to a high pressure chamber and a low pressure chamber and controlling the flow- down length of braze material through the utilization of the differential pressure thereof or doing  other in the brazing device for sleeve and conduit tube.   
     CONSTITUTION: A sleeve 2, conduit pipe 4, etc. are assembled and the assembly is contained in a  hermetic vessel 8. The hermetic vessel 8 is divided to a high pressure chamber 18 and a low pressure chamber 19 and a fluid resistor 16 is raised and supported from the lower part of the through  part of a pipe plate 1 by a support jig 17 to increase the fluid resistance of the gap between the  sleeve 2 and conduit tube 4. The high pressure chamber 18 and low pressure chamber 19 are  brought under inert gas or reducing gas atmosphere and current is supplied to coils. When a temperature switch 13 senses the melting start point of the braze material, a differential pressure control unit 12 maintains the pressure difference between the high pressure chamber 18 and low pressure chamber 19 constant. Because of this differential pressure, the melted braze is forced in the  gap between the sleeve 2 and conduit tube 4. In addition, the variations in the fluid resistance  owing to the varying sizes of the gap are concealed by the resistor 16 and the flow-down length of  the braze material becomes even in the circumferential direction.

The pattern formed by the diffracted light 63 is capable of changing the hologram pattern. The refractive index of the irradiated part is changed by locally irradiating the light beam path 50 with the UV light 62 in such a manner, by which the reflection parts having desired reflected light spectra are obtd.

Title: Supervising device in loop network
Inventor: NAKAI SHOICHIRO
Filed: 1986-01-16
Abstract: PURPOSE:To detect the abnormal condition of a signal on a transmission line with a simple hardware by initializing a timer each time a detecting means detects the starting of the signal and deciding that a trouble occurs when a timer informs of the progress of a constant time specified based on the open- loop delaying time of the transmission line and the maximum length of the signal. CONSTITUTION:An SD detecting device 14 detects a starting delimiter SD of a bucket to pass on a transmission line 6. A timer 15 is the one to measure the progress of a constant time specified by the open-loop delaying time and the maximum bucket length of the transmission line 6and starts to measure the initialized time progress by an SD detecting output from the SD detecting part 14. Consequently, at the time of the normal action, the timer 15 is initialized by the SD detecting part 14 before the set time is measured and an output 15-1 of the SD detecting part will not come to be an activated condition. When the detecting interval of the starting delimiter SD exceeds the maximum value of the interval of the usual SD detection, the timer 15 makes the output 15-1 into the activated condition and informs a transmitting part 16 that the abnormality occurs.

Title: Moving blade of turbine
Inventor: TAKI TOMOYUKI
IPC: F01D5/14
Filed: 1992-01-16
Abstract: PURPOSE:To prevent erosion of moving blades by changing a collision angle of water droplets against the blade surface through forming the sectional shape of the blade to have an acute aggle at the front adge of the moving blade in the final stage of the turbine. CONSTITUTION:The sectional shape of a blade at the front edge of a moving blade 2 of a low pressure turbine is formed to have an acute angle, and in addition, an angle THETA between the back face 17 of the moving blade, which forms the acute angle, and the moving direction of the moving blade 2 is determined so as to be smaller than a required angle. By this constitution, a yertical component of the flow velocity to the blade surface becomes lower than the critical velocity Vc for the blade material, and erosion can be reduced remarkably. Thus, erosion can be well and economically prevented by reducing collision velocity (a component vertical to the blade surface)and also imput force due to water droplets.

Abstract: PROBLEM TO BE SOLVED: To improve reliability for detecting the rotational position of a disk. SOLUTION: A gray code sector number 104 is assigned in a gray code, and a servo zone counter circuit 4 is not started until the certainty and continuity of the gray code sector number 104 are detected.

Moreover, a failure of the servo zone counter circuit 4 can be detected by comparing the gray code sector number 104 and a servo zone number signal 110 which is the output of the servo zone counter circuit 4.

Abstract: PURPOSE:To cope with the change of a frequency signal source by the same circuit diagram by providing various frequency signal sources, a selector which selects one of them, a frequency divider which generates a normalization signal, and a tuner which extracts a clock by it. CONSTITUTION:Frequency signal sources 1 to be synchronized are a frequency group of, for example, 64, 128, and 256kHz, which are correlative with one another. Therefore, the normalization signal in the frequency group is defined by using divisors. Namely, the normalization signal is generated by the frequency divider 3. Frequency signals from the frequency signal sources 1 are sent to the selector 2, which selects one of those frequency signals. Then, the selected frequency signal is sent to the frequency divider, which divides its frequency to generate the normalization signal. Finally, the normalization signal is sent to the tuner, which extracts the clock.
