Title: Cold storage chamber
Inventor: SUNAGA MAMORU
IPC: F25D16/00
Filed: 1988-07-04
Abstract: PURPOSE:To make mechanical and electrical control unnecessary and obtain a desired cold storage space temperature by a method wherein the amount of fluctuation of an ambient temperature and the desired cold storage space temperature are estimated while the heat exchanging area or the heat accumulating temperature of a cold accumulating member set so as to balance the amount of invading heat with the amount of exchanging heat. CONSTITUTION:Plate type heat accumulating members 5, provided with evaporating pipes 6, are arranged so as to be brought into contact with the outer wall surfaces of the inner casing 2 of a cold storage chamber 1. At least one of the latent heat temperature and the heat exchanging area of the cold heat accumulating member 5 is designed so that a value, obtained by the product of a difference between a temperature in a cold storage space and the latent heat temperature of the cold heat accumulating member 5 by a heat exchanging area or the area of the cold heat accumulating member 5 contacting thermally with the inner casing 2 by the heat transfer coefficient of the inner casing 2 in contact with the cold hat accumulating member 5, becomes equal to the amount of invading heat. According to this method, the temperature in the cold storage space may be controlled surely and simply without effecting any mechanical or electrical control.

Title: Method and apparatus for detecting flaw in welded part and the like with ultrasonic wave
Inventor: IWASAKI AKIO
IPC: G01N29/04
Filed: 1987-06-30
Abstract: PURPOSE:To make it possible to ensure simple flaw detection, by dividing a part, whose flaw is to be detected, into several stages in the direction of a depth, combining and arranging a plurality of slant angle probes so as to measure the divided sections at individual depths separately, and detecting the flaw. CONSTITUTION:The height of a flaw part to be detected is divided into, e.g., four stages. The range of T/4 from the top is measured with slant angle probes 11 and 11'. The range of T/2 from the top is measured with slant angle probes 12 and 12'. The range of 3T/4 is measured with slant angle probes 13 and 13'. The transmitting probes are arranged at the positions close to the flaw detecting position. The receiving probes are arranged at the remote side from the flaw detecting position. For the remaining range of T/4, a slant angle probe 14 is arranged for one probe method. A material A, whose flaw is to be detected, or the probes 11 and 11'-13 and 13' and 14 are moved with the specified arrangement being kept. An echo from a defect is caught with the transmission and reception of ultrasonic waves from the probes. The entire surface of the vertical cross section of the flaw part to be detected is detected with the probes. The data, which are sent from the probes for each divided stage to the computer of a control part, are compared with the data, which are inputted beforehand, and operated with the computer. Thus the continuous state of the defect at the vertical cross section surface at the flaw part to be detected is judged.

Title: Through-type capacitor
Inventor: KUROKUZUHARA MAMORU
IPC: H01G4/35
Filed: 1987-07-03
Abstract: PURPOSE:To prevent a dielectric from being broken by a method wherein an upper end of a lower-part external housing is sandwiched between an external face where one part of an external peripheral edge part of a ring-shaped conductor sheet is folded downward and an inner face of a circular stepped part of a conductor sheet electrode so that a strong contraction stress cannot be exerted on a lowerhalf part of the dielectric. CONSTITUTION:A ceramic dielectric 1 is cylindrical and has a through hole; an inner wall face of this hole and an outer wall face are metallized by using a nickel-plating method or the like. A stepped part is formed at a nearly middle position of a height of the dielectric 1; a diameter at a lower-half part is smaller than that at an upper-half part. A central conductor 2 functioning as one electrode is inserted into the through hole of the dielectric 1 and is soldered. A grounding electrode sheet 3a functioning as the other electrode has a circular stepped part where an upper-part external housing 4 is put and a hole which is cencentric with the circular stepped part to which the lower-half part is attached. The dielectric 1 is supported by this grounding electrode sheet 3a at the stepped part and is soldered. A cylindrical part 31 which is formed at a peripheral edge part of the hole for dielectric supporting use of the grounding electrode sheet 3a and which is folded downward along an external peripheral face of the dielectric prevents a contraction stress by a lower-part external housing 5 and an insulating filling resin 6 from being exerted on the dielectric 1.

IPC: B05D1/04
Filed: 1990-06-26
Abstract: PURPOSE:To apply a uniform coat of wax to a strip in its width direction by providing a pair of driving rolls immediately behind an electrostatic coating device. CONSTITUTION:In an electrostatic coating part A, wax is supplied to a bell part 1 and atomized by applying high voltage across the bell part 1 and a strip 2.

Title: Access circuit of image memory and printer using it
Inventor: SUZUKI MASAYOSHI
IPC: G06F12/02
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To prevent overrun from occurring during printing and to improve the efficiency of image development in a printer. SOLUTION: When data are transferred from a cache to an image memory 3, a CPU continuously transfers a portion of a line of the cash by making a CPU continuous signal true. When transferring of a video is required from a video conversion part 4 during it, a priority judging part 2 judges whether a specified amt. of transferring among a line is finished in referring to an address accessed by the CPU and sends the result to a bus arbitrating part 1. The bus arbitrating part 1 continues the access from the CPU as it is if a specified number of transferring is finished and temporarily stops the access from the CPU if it is not finished and performs reading-out from the video conversion part. It is possible to efficiently develop and output an image by making a requirement for transferring of the video wait within a range where overrun is not generated like this.
