Abstract: PURPOSE:To obtain a sharp image of a desired part by converting the sound speed in a body into the sound speed in water, finding the focal distance in the water from it, and specifying the height of a probe when forming an ultra sonic image as to the body in the water. CONSTITUTION:When an ultrasonic image of a defect part in the body is formed by making a probe scan on the body arranged in the water mechanically, the height of the tip of the probe is fixed to Z found from an equation I and the probe is put in scanning operation. Here, f is the focal distance mm of the probe in the water, t the thickness mm of the body, v1 the sound speed m/s in the water, v2 the sound speed m/s in the body, and x the position mus of a defective wave in an ultrasonic wave flaw detection waveform. The height of the probe tip is expressed by an equation II when the ultrasonic image of the part of the body of specific depth from the upper surface by making the probe scan against the body arranged in the water by the ultrasonic video forming method with the proper focal distance. Here, f, t, v1, and v2 in the equation are the same with the equation I, d is the depth mm of a part to be measured from the upper surface, and the height of the probe is thus deter mined.

Abstract: PROBLEM TO BE SOLVED: To prevent the production of clinker as well as the burnout of refractories of a fire grating by a method wherein a stepped body is provided between an integrated drying and combustion type stoker and a post-combustion stoker. SOLUTION: Waste is supplied to the drying stoker unit 5 of an integrated drying and combustion type stoker 2 and is dried. Then, the waste is burnt on the combustion stoker unit 6 after being reversed sand stirred by a stepped unit 7. The waste from the integrated drying and combustion type stoker 2 is supplied to a stepped body 4, reversed stirred, and burned on a post- combustion stoker 3 through surface combustion. The integrated drying and combustion type stoker 2 supplies comparatively thin layers of garbage into the drying stoker unit 5 when the garbage is provided with a low calorific power. On the other hand, when the quality of the garbage is provided with comparatively high calorific power, comparatively thick layers of garbage are supplied into the drying stoker unit 5.

Title: Coupling circuit
Inventor: OOTA KAZUO
IPC: H04L12/40
Filed: 1980-11-06
Abstract: PURPOSE:To prevent the lowering in the impedance of a bus transmission line, by constituting a transmission drive circuit which is interrupted other than signal transmission. CONSTITUTION:A stationary base bias voltage is not applied to a base terminal of a transmission transistor (TR)312, which turns on only when the modulation signal is positive. Thus, at the reception state where no modulation signal is applied to the base terminal, this TR312 is non-conductive and it is not a load to a bus transmission line 1. If data are transmitted from a master station not shown at this reception state, this signal is received at a receiver 303 with high input impedance. With the constitution like this, even if a plurality of terminals are connected to the line 1, since the transmission TR is non-conductive and the input impedance of the receiver is high, the impedance of the line 1 is not decreased.

Inventor: NAGAO MASASHI
IPC: F24D3/18
Filed: 1984-07-27
Abstract: PURPOSE:To effectually utilize energy, by combining an absorption-type water heating/ cooling unit, which uses the waste heat of exhaust gas of an engine and that of its cooling water from a water jacket to produce cold water and hot water, with an electric power generation means. CONSTITUTION:Cooling water drained from the water jacket of an engine 1A for driving an electricity generator 1B is returned to the engine through a pipe 17, a low- temperature regenerator 5, a first three-way control valve 14, a heat exchanger 3 between the cooling water and other cooling water, a second three-way control valve 15, a water heater 6 and a pipe 17b so that an absorption-type water heating/cooling unit is operated as a room cooling cycle. When the unit is operated as a room heating cycle wherein room heating and hot water supply are only performed, the cooling water from the water jacket by-passes the low-temperature regenerator 5 and flows through the heat exchanger 8 and a heat exchanger 9 which heats water by the cooling water from the water jacket to perform the room heating and hot water supply. The heat of exhaust gas introduced into a high-temperature regenerator 4 is transferred from a water heater 6 to the cooling water from the water jacket so that heat abandoned in a cooling column 10 is reduced as the load in the room heating and hot water supply increases.
