Abstract: A steam turbine in which principal components to be exposed to high temperatures are all made of ferritic steel, whereby the temperatures of main steam and reheat steam can be increased to 610-660 (.degree.C.). The rotor shaft (23 in FIG. 1) of the steam turbine is made of ferritic forged steel whose 100,000-hour creep rupture strength is at least 15 (kg/mm.sup.2) at the service temperature of the rotor shaft. Likewise, the casing (18) is made of ferritic cast steel whose 100,000-hour creep rupture strength is at least 10 (kg/mm.sup.2). The steam turbine of high thermal efficiency can be applied to a steam-turbine power plant.

Abstract: In an improved method of treating foul water, the solids that are produced during the process of treatment of foul water such as wastewater or liquid sludges are treated with a heat treatment apparatus and the resulting thermal energy and/or gas is utilized in the treatment of said foul water. The foul water may be subjected, directly and/or after a treatment, to a filtration step using a filter packed with nonflammable particulate matter such as sand, and the trapped solids are fed into a fluidized-bed heat treatment apparatus such as a fluidized-bed incinerator or gasification furnace and, thereafter, the nonflammable particulate matter in the heat treatment apparatus is returned to the filtration step. The foul water can be treated with effective utilization of the energy of the organic matter in the foul water or the solids that are produced during the process of its treatment.

Abstract: The improved method of treating an exhaust gas from a combustion apparatus comprises adding ammonia to the exhaust gas and then irradiating it with an electron beam, characterized in that part or all of said ammonia is supplied as a separated portion of ammonia-containing water. The ammonia-containing foul water may contain feces excreted from humans and/or domestic animals and poultry, fermentation industry liquid waste or food processing wastewater. The organic waste-containing water may be digested anaerobically to convert the organic matter to methane gas and, subsequently, ammonia is separated from the supernatant liquor and used as the source of ammonia to be supplied. The methane gas is suitably used as a source of energy for the combustion apparatus. At least part of the organic matter in the organic foul water may be decomposed oxidatively and, subsequently, ammonia is separated for use as the source of ammonia to be supplied.

Abstract: An operation display method and apparatus for variables of an oscilloscope including a rotary-push mechanism connected with a rotary knob is disclosed. When the rotary knob is rotated clockwise a little, a right directional arrow is displayed on a CRT. Then e.g. a cursor is shifted to the right on the CRT by a division every pushing the rotary knob. When the rotary knob is rotated clockwise or counterclockwise, the cursor is shifted a little to the right or the left. When the knob is rotated counterclockwise in the precise adjustment, a left directional arrow is displayed on the CRT. Then the cursor can shifted to the left on the CRT by a division every pushing the knob. Other variables can be operated in the same manner.

Abstract: In a computer network system having a plurality of on-line connected computer systems, each computer system has means to monitor the amount of jobs of its own computer system. Each computer system requests a job to another computer system when the amount of jobs of its own computer system is in short, and the requested computer system transfers a job to the requesting computer system if the amount of jobs of the requested computer system is enough. Each computer system also requests transfer-out of a job to another computer system when the amount of jobs of its own computer system is over, and the requested computer system accepts the request if the amount of jobs of its own computer system is not full, and the requesting computer system transfers the job to the accepting computer system. In this manner, loads to the computer systems are distributed.

Abstract: A rocking massage chair wherein massaging wheel elements and their drive mechanism are disposed in backrest part of the chair while a motor for driving an operating shaft of the drive mechanism is disposed in seating part of the chair, whereby the relatively heavy motor is located on forward side of a rocking center of the chair so as to keep the center of gravity of the chair always on the forward side and thus to prevent the chair from overturning rearward.

Abstract: In the fabrication of an electronic circuit such as an integrated circuit, a method of determining the arrangement of logic circuit devices on a circuit board on the basis of a logic data defining the logic circuit devices and the interconnections among them. The logic circuit devices are classified in groups in accordance with a degree that each signal line connected with the logic circuit devices requires the expedition of signal propagation therethrough. First, the logic circuit devices belonging to the group pertinent to the highest degree are arranged, and next those belonging to the group pertinent to the second highest degree are arranged. Such a processing is carried out for all the groups.

Abstract: A high-strength austenitic steel having a fully austenite structure and consisting essentially of 0.02 to 0.15 wt % of C, not greater than 1.5 wt % of Si, not greater than 2.5 wt % of Mn, 8 to 20 wt % of Ni, 13 to 25 wt % of Cr, 0.02 to 0.25 wt % of Al, not greater than 0.1 wt % of N, at least one of 0.001 to 0.01 wt % of B, 0.02 to 0.5 wt % of Nb, 0.01 to 0.2 wt % of Ti and 0.02 to 0.6 wt % of V and the balance substantialy Fe, with the weight ratio (Al/N) ranging between 1 and 4.5. This steel is suitable for use as the material of, for example, inner casing of steam turbine, valve body incorporated in the steam turbine, rotor shaft, and chemical equipment such as reaction pipe and vessel for styrene monomer producing facility.

Abstract: Chargeable electric instrument of watertight housing capable of still discharging abnormally generated gas or liquid from built-in storage battery. The instrument includes a gas discharging valve means provided at an open end of a storage-battery casing, a cap means fixed to the casing for liquid-tightly enclosing the open end and valve means, a charge current feeding means provided in an end part of the housing, and a gas or liquid flow-path means made through the cap means and housing while preventing an entry of any fluid from the exterior, whereby any explosive gas internally generated can be effectively discharged through the valve, cap and flow-path means to the exterior.

Abstract: A method of measuring fat content of meat includes the steps of immersing a meat sample in a liquid, and detecting the amount of displacement of the liquid by the meat sample, the variance of such displacement as a function of fat content being predetermined, whereby the fat content is determinable from the detected displacement.

Abstract: An electric dry shaver with an inner blade block including a parallel array of semiconductor shearing blades and reciprocally driven along inner surface of a flexible thin outer blade mounted substantially in a semicylindrical shape of an outer blade block by means of a vibrating device through a reciprocal driving shaft detachably and resiliently connected to a connecting means pivotably provided in the inner blade block substantially at the center of gravity thereof. The connecting means is pivoted to the inner blade block at an axis passing substantially the center of gravity and intersecting at right angles longitudinal axis of the semicylindrical outer blade in a plane perpendicular to a plane including reciprocal directions of the driving shaft and the connection of the driving shaft to the connecting means is performed at a position adjacent the pivoting axis of the latter.

Abstract: An electric dry shaver of reciprocally vibrated type having long hair trimmer which is driven only when a coupling member mounted to drive means is coupled to clipper cutter of the trimmer by trimmer operating handle manually operated. The clipper cutter has a joint member and the coupling member is normally biased away from engagement with the joint member. The handle as operated into trimmer operating position engages the coupling member to urge it into engagement with the joint member so that the clipper cutter will be coupled to the drive means.
