Title: Boiler for automatic food feeder
Inventor: MAKITA TAKATSUGU
IPC: F24H1/18
Filed: 1990-09-18
Abstract: PURPOSE:To prevent a temperature of applied water from being decreased under a replenishing of water by a method wherein a boiler is comprised of a plurality of heating chambers having a heating means therein and arranged continuously in sequence, a water supplying port, a water discharging port and water passages alternatively arranged at either an upper part or a lower part of a heating chamber along a water flow direction CONSTITUTION:As a valve is opened, heated water is discharged out of a heating chamber 23 through a pipe in a direction of arrow E and then hot water is consumed, a liquid surface sensor detects a consumption of water and the cold water is fed into the heating chamber 20 in a direction of an arrow A. Water corresponding to an amount of fed water is sent in sequence in directions of arrows B, C and D through water passages disposed in each of the partitions 14 to 16 toward heating chambers 20 to 23 and then when a specified amount of water is detected by the liquid surface sensor in the heating chamber 23, the water feeding is stopped. Cold water supplied to the heating chamber 20 is not directly mixed with water of high temperature stored in the heating chamber 23, but water supplemented to the heating chamber 23 is a well-heated water in the heating chamber 22, so that the water in the heating chamber 23 does not drop its temperature rapidly and the water reaches to a predetermined temperature within a short period of time under a light supplemental heating.

IPC: F25D23/06
Filed: 1987-09-30
Abstract: PURPOSE: To conceal deformation at the rear corner of an inner box without increasing the number of parts by providing an intermediate partitioning shelf integrally with a rising part for concealing a protrusion at the rear corner. CONSTITUTION: An intermediate partitioning part comprises a front partitioner 13, an intermediate partitioning member 14 and an intermediate partitioning shelf 25. The intermediate partitioning shelf 25 is made of a pan-like injection molded part having a rear rising part 26 not shorter than a protrusion 21 at a rear corner and a side rising part 27 of same height as the rear surface molded integrally on the side of an inner box 2. The intermediate partitioning shelf 25 is held by the member 14, the rail part 16 of the inner box 2, and the rear rail part 20 of the inner box 2. Since the rear rising part of intermediate partitioning shelf conceals the protrusion at a rear corner of the inner box 2, deformation thereof resulting from foaming pressure can be concealed at the time of filling a heat insulating material without increasing the number of parts.

Title: Monitoring alarm for particulates in the air
Inventor: ISHII TSUTOMU
IPC: G01N21/53
Filed: 1989-09-22
Abstract: PURPOSE:To generate an alarm sound when particulates reach a set value by letting the particulates contained in the sample air scatter a laser beam. CONSTITUTION:An exhaust pipe 4 is connected to the lower end of an exhaust nozzle 3b. A suction pump 5 sucks the outside air into a casing 1 via a suction pipe 2 and a suction nozzle 3a. A flow adjusting apparatus 6 adjusts the flow rate of the air. When the sample air passes an opening G, an irradiating unit 7 irradiates laser light, which is scattered by particulates in a sample and a light trap 19 absorbs the laser light which is not scattered. Two aspheric lenses 17 and 18 collect the scattered light to feed it to a photodetector 21, which converts the scattered light to electric signals. The signal processing system of a printed circuit board 22 amplifies the electric signals, analyzes a waveform, counts the signals and, when a given value set in advance is reached, the signal processing system can operate an alarm.

Title: Rotary anode target for x-ray tube and its manufacture
Inventor: IMAI SATORU
IPC: H01J35/10
Filed: 1988-09-30
Abstract: PURPOSE:To enhance the bond strength of a heat radiating plate with an X-ray generating body by forming the heat radiating plate from aluminum nitride. CONSTITUTION:A rotary anode target 7 is equipped with a heat radiating plate 13 and an X-ray generating body 14. Aluminum nitride forming the heat radiating plate 13 has high melting point, having lesser extension to tungsten, etc., constituting the X-ray generating body 14 at the max. service temp. of a rotary anode target 7, and also it has a coefficient of thermal expansion near tungsten. The aluminum nitride exhibits a high thermal conductivity even at high temps. and also a comparatively large specific heat and a larger heat capacity, so that the heat generated in the X-ray generating body 14 because of collision of accelerated electron is radiated effectively through the radiating plate 13. This increases the bond strength of the radiating plate with X-ray generating body and provides good cooling performance.

Title: Detecting method for defect inside light-transmitting object
Inventor: KURUMISAWA MAKOTO
IPC: G01N21/88
Filed: 1993-10-04
Abstract: PURPOSE:To carry out sure and easy inspection of a defect inside a light-transmitting object without necessitating a liquid of an equal refractive index and in a noncontact manner by placing the focus for detection on the defect through the end face of the light-transmitting body. CONSTITUTION:On the occasion of detecting a defect 10 inside a lighttransmitting object 2 of which the surface and rear are light-scattering faces 4, a laser light 7 is applied through the light-scattering face 4 or another end face from a light source 6. The laser light 7 becomes a scattered light source at a line 9 on the light-scattering face 4, and when the defect 10, e.g. a bubble, exists on the face, the light is reflected and scattered and forms a luminant spot. A lightsensing system and a photodetector, e.g. a camera 1, placing the focus on a plane being parallel to the end face 3 and containing the line 9 come to place the focus on the luminant spot of the defect 10 and detects it. By scanning the object of inspection in this way, inspection of the whole object is enabled. Thereby the defect 10 can be specified on a linearly defined section on which the laser light 7 hits, that is a scanning position, and further it can be detected three-dimensionally from the detected position of the luminant spot in the camera 1.
