摘要： A screw shaft, a nut, and a conduit member are made of metal material, and a solid lubrication film is coated on inner walls of thread grooves thereof and a ball circulation path of the conduit member. Where d1 is the inner diameter of the ball circulation path of the conduit member, d2 is the groove diameter of the screw shaft, d3 is the diameter of each ball, and h1 is a clearance between the screw shaft and the end portion of the thread groove (as well as the end portion of the conduit member), respective members are arranged so as to satisfy relations of (.vertline.d1-d2.vertline./d3).ltoreq.1/40 and h1/h3.ltoreq.1/40. As a result, it is possible to provide a ball screw mechanism in which film-transfer lubrication is achieved between the members and the durability and precision are improved.

摘要： A plurality of chambers are partitioned in a muffler by a baffle board. The muffler is provided with an exhaust gas passage for discharging exhaust gas outside the muffler via these chambers and a valve that bypasses a part of the exhaust passage. This valve opens according to the exhaust gas pressure. Also provided are a mechanism for pushing the valve in a closing direction, and a mechanism for damping the shock when the valve closes. Thus, valve closing noise is suppressed, and exhaust gas noise is further suppressed.

摘要： A recording apparatus using a semiconductor laser comprises a video signal processor which reduces the time for conduction of current in a semiconductor laser diode by cutting away a pulse signal for turn on/off of the semiconductor laser diode at its leading and trailing edges. For both a one pulse signal representative of an isolated one dot and a one pulse signal representative of continuous plural dots, the signals being transmitted from a host, the processor contracts the pulse width of the pulse signal at its leading and trailing edges to permit uniform recording which is not influenced by the manner of arranging dots.

摘要： An apparatus for measuring the flow rate of water vapor in a process gas including steam includes a sample system having a dew point meter and a pressure meter, and an inert gas supply device for mixing an inert gas with a process gas in the sample system. The process gas comprises a first gas, such as natural gas, and steam. A partial pressure calculating unit calculates the partial pressure of the water vapor contained in the gas mixture on the basis of the dew point of the mixture measured by the dew point meter and the pressure measured by the pressure meter. A flow rate calculating unit calculates the flow rate of the steam contained in the process gas on the basis of the water vapor partial pressure, the inert gas flow rate, and the flow rate of the first gas in the process gas.

摘要： An apparatus for processing a binary video signal carrying information of dots to be printed. The binary video signal is at a relatively higher or lower level for the whole of each bit time to constitute a unit portion of the binary video signal. The unit portion of the binary video signal at one of the levels is representative of one dot. The apparatus includes a first detector for detecting a start of a length of each of those parts of the binary video signal which are at the one level, a second detector connected with the first detector for determining the number of unit portions contained in each part of the video signal, a generator connected with the second detector for producing one or more dot pulses for each part of the video signal, each of the dot pulses having a pulse width smaller than that corresponding to the bit time, the number of the one dot pulses being the same as that of the determined number of unit portions, and a controller connected with the generator for controllably adjusting the pulse width of the dot pulses.
