IPC: H01J61/54
Filed: 1979-11-14
Abstract: PURPOSE:To prevent the slipping off of a belt and diminish the ascending of temperature by using a metal having same coefficient of thermal expansion as that of a luminous tube body, as the material of a heat-resisting metallic belt. CONSTITUTION:As for a luminous tube body 1 such as a high pressure sodium discharge lamp, etc., its electrical conductors 3 and 3' are fixed with frame wires 7 and 8 as input terminals through conductors 13 and 14 and a starting auxiliary body 12 made of heat-resisting metallic conductors is coiled round the outercircumference of the luminous body 1.

Title: Incontinence preventing sensor
Inventor: KOYAMA JUN
IPC: A61F5/44
Filed: 1987-06-12
Abstract: PURPOSE:To allow said person to go to a toilet, by arranging an ultrasonic sensor in the vicinity of the bladder of a human body to transmit an ultrasonic wave of several MHz toward the bladder and receiving the reflected wave from the bladder to measure the amount of urine and sensing the sign of incontinence to inform the same to said person. CONSTITUTION:When a transmission order circuit 1 performs a transmission order at an arbitrary time interval, an ultrasonic wave is emitted to the inner wall of the bladder 1 by an oscillation amplifier 4 and and ultrasonic vibrator 3. The reflected wave from the bladder 1 is amplified by a receiving amplifier 5 and the time difference between the transmitting wave and the receiving wave is operated by a time measuring circuit 7. If urine is not accumulated, the time difference is short but, when urine is accumulated, the diameter of the bladder expands and the arrival time of the reflected wave becomes long. Therefore, by informing the sign of incontinence to the said person by a judge circuit 8 having a threshold value lower than the amount of urine reaching incontinence and an alarm 9, incontinence can be prevented. In the case of a woman, this sensor is arranged to the lower part of the public symphysis and, in the case of a man, an oscillator is arranged to the lower part of the prostate to make it possible to sense the sign of incontinence.

Abstract: PURPOSE:To achieve a lowering of an error rate by controlling a threshold level so that a difference between the number of bits corrected from 1 to 0 per error correction block of reproduction information and the number of bits corrected from 0 to 1 reduces. CONSTITUTION:An analog signal from a magnetic head 1 is binary coded with a comparator 3 through an amplifier 2.

An addition is made with an adder 9 to a reference voltage supplied from a reference voltage generator 10 through a window comparator 7 and an integrator 8 based on a difference of the number stored in the registers 5 and 6 and the results are defined as threshold voltage of the comparator 3. Thus, the threshold voltage is controlled so that the frequency of the correction to 0 from 1 almost equals the frequency of the correction to 1 from 0, thereby lowering an error rate.

Title: Fatigue inhibitor for heat transmitting tube
Inventor: AMAMIYA HIDE
IPC: F28F19/06
Filed: 1982-08-27
Abstract: PURPOSE:To prevent heat transmitting tubes from being damaged, by flame- spraying metallic powder to the surfaces of heat transmitting tubes which are supported by baffle plates. CONSTITUTION:A heat transmitting tube 10 is preliminarily treated so as to be ready to be flame-sprayed, by hardening the surface of the tube 10 by means of shot blasting or sandblasting, and by defatting using trichlene. Then, the mixed powder, consisting of less than 94wt% of titanium dioxide, oxide powder of 4- 8wt% of aluminum, and 2-6wt% of vanadium, and nickel and chrome alloy powder consisting of 12-18wt% of chrome, 5-9wt% of iron, and nickel for the remainder wt%, is flame-sprayed to the surface of a heat transmitting tube. In this case, less than 1mm. is enough for the thickness of a layer to be flame- sprayed, but for fear that a little number of pin holes will be formed in the flame-sprayed layer, it is necessary to fuse the part by heating it with flames immediately after flame-spraying.
