Title: Heat exchanger and method for restoring heat transfer pipe supporting function of the same
Inventor: TAKAHASHI MASARU
IPC: F28F1/32
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To enable the prevention or repairing of vibration abrasion, thinning, corrosion and erosion of a heat transfer tube supporting plate and tube hole with a low cost without necessitating the long period of periodical inspection by a method wherein flowable filler is poured into a gap between the outer surface of a heat transfer tube and the wall surface of tube hole on a heat transfer tube supporting plate to cure it. SOLUTION: A plurality of heat transfer tube supporting plates 9 are installed in a cylinder 10 so as to be arranged with a proper interval and flowable filler 11 is applied on the heat transfer tube supporting plates 9. The flowable filler 11 is provided with good flowability immediately after being produced whereby flows easily into gaps between the tube holes on the heat transfer tube supporting plate 9 and the heat transfer tubes 12 by pouring it along the wall surface of the heat transfer tube supporting plates 9 whereby the filler soaks easily into not only the outer peripheral part of a tube nest but also into the central part of the same.  In this case, the flowable filler 11 is cured at a normal temperature after being produced while the flowable filler 11, adhered to the surface of the heat transfer tube supporting plate 9 and cured, not only blocks a gap between the tube hole of the heat transfer tube supporting plate 9 and the heat transfer tube 12 but also functions as the supporting plate of heat transfer tubes by itself.

Title: Video signal measuring instrument
Inventor: OKUDA HIROYUKI
IPC: H04N17/06
Filed: 1987-02-19
Abstract: PURPOSE:To always obtain a stable sampling clock by deciding whether or not the main output of a second PLL circuit is in a regulated value between synchronizing signals, and switching the inputs to a first and the second PLL circuits by the output of said decision. CONSTITUTION:A synchronizing signal deciding means 9 counts the main output of the second PLL circuit 13 i.e. the output of an oscillator 13d, and decides whether or not the counting is in the regulated value; if it is, the synchronizing signal is normal, and the means 9 supplies the synchronizing signal to the second PLL circuit 13 via a switching means 12. Also, if the counting value is out of the regualted value, the synchronizing signal is abnormal, and the frequency division output of the first PLL circuit 10 is supplied to the second PLL circuit 13 via the switching means. When the counting value is in the regulated value, a synchronizing signal is supplied to the first PLL circuit 10, and if not in the regulated value, the supply of synchronizing signal is interrupted. As a result, always stable sampling clocks suitable for the digitizing of data can be generated.

Title: Inspection of wiring for wafer scale integrated circuit
Inventor: TSUCHIYA SHINPEI
IPC: H01L21/66
Filed: 1986-02-20
Abstract: PURPOSE:To inspect interblock wirings for a circuit in a short time without using the wide area of a wafer by constituting a single circuit system by a plurality of wirings constituting the interblock wirings, testing the performance of the single circuit system and deciding nondefective or defective interblock wirings by the result of the test. CONSTITUTION:Wirings 41-4n constituting interblock wirings are connected in series, and pads 51-5m and 61-6m are formed previously at the terminals of the series circuits. The length of one sides of the pads 51-5m and 61-6m requires approximately 30-50mum, but 10mum or less is sufficient as the width of the wirings 41-4n, and wiring spaces are brought to 5mum or less, thus collecting approximately five wirings 41-4n. On measurement, a pulse signal is inputted from one pad 51, and output signal pulses are detected synchronized with an input in another pad 61. The utilization factor of a wafer is improved because regions required for wirings are reduced, and the time required for measurement is also shortened because the number of measurement is decreased.

Title: Melting furnace
Inventor: IWAI NOBUYUKI
IPC: F23G5/00
Filed: 1990-02-20
Abstract: PURPOSE:To prevent clogging of an outlet port caused by molten slag by a method wherein a temperature of the molten slag near a slag outlet port is kept higher than a melting point of the slag. CONSTITUTION:In the event that a temperature in a melting furnace is rapidly decreased by a variation of a state of material to be melted or an operating condition, a temperature at a part of a slag outlet port 15 is kept high by a radiation heat got from a heat accumulation plate 21. Even in the event that the molten slag is left in the melting furnace just after the operation of the melting furnace is stopped, a temperature at a part of the slag flowing-out port 15 is kept high for a while with a radiation heat from a heat accumulation plate 21. Accordingly, it is possible to discharge the molten slag remaining at the part of the slag flowing-out port 15 completely from the slag flowing-out port 15 toward a slag discharging port 10. With such an arrangement, a clogging with the slag at the slag outlet port 15 is prevented.
