摘要:
A method for forming a lubricant coat on a surface of steel slug to be forged and a forging device provided with a lubricant coat forming system. The method makes possible the forging of hard to work material, such as stainless steel. Highly durable parts can be manufactured easily. The durability of the metal molds of the forging device is increased, thereby decreasing the cost for the manufacture of the parts. In the method, the uniformly thick lubricant coat can be formed easily even on the transformed end surfaces of the material being worked, providing effective lubrication. The lubricant coat forming member can replace the oil lubrication of the related-art forging device of the inline type, in which the cut end surfaces of the material are not lubricated, without modifying the structure of the related-art forging device especially. The forging device of this invention continuously forges the material, lengthening the interval for replacing metal molds and decreasing the cost for the manufacture of the parts.
摘要:
In a magnetic recording/reproducing apparatus of the helical scanning type the rotation speed of the reels in operation is detected and it is judged to be abnormal, if the rotation speed exceeds the upper limit thereof. This upper limit can be varied, depending on various operating modes. When an abnormality is detected, the brake of the reels is driven and the rotation of the drum is stopped. After the tape has been stopped, the tape is unloaded while rotating the supply side reel and the take-up side reel, the drum remaining not rotated.

An ultrasonic diagnosis apparatus comprises an ultrasonic probe for transmitting an ultrasonic pulse beam toward an internal moving medium of a living body at a constant recurrence frequency, a converter for mixing the received high-frequency signal with a set of complex reference signals having a frequency n times as high as the recurrence frequency of the transmitted ultrasonic pulse beam and having a complex relation therebetween, thereby converting the high-frequency signal into complex signals, a speed operating circuit for computing the moving speed of the internal moving medium on the basis of the complex signals, and a display unit for displaying the moving speed in real time. The apparatus may include a speed dispersion operating circuit for computing the dispersion of the moving speed computed by the speed operating circuit in order to display both the moving speed and the dispersion thereof on the display unit.
摘要:
An ultrasonic diagnosis apparatus comprises a probe means for transmitting an ultrasonic pulse beam toward an internal moving part of a living body and receiving the reflected wave therefrom, and a plurality of phasing circuits for simultaneously receiving and phasing the received signal in parallel in a plurality of channels. The received signals of plural channels are mixed with a set of complex reference signals having a complex relation therebetween, thereby converting the received signals into complex signals. A multiple-channel multiple-cancel complex signal canceller with feedback removes reflected signal components from a low-speed moving part and/or a stationary part of the living body. Speed and speed dispersion operating circuits compute the moving speed of the moving part on the basis of the complex signals and the dispersion thereof, respectively. The results of computation are subjected to image processing.
摘要:
An ultrasonic diagnosis apparatus obtains an ultrasonic wave image of B mode by transmitting an ultrasonic pulse beam toward an internal moving part of a living body at a constant recurrence frequency and receiving the reflected wave therefrom. A speed distribution operator detects a frequency shift of the reflected wave Doppler-shifted by the internal moving part, thereby computing the distribution of the moving speed of the internal moving part. The speed distribution image of the internal moving part is displayed on the basis of the output of the speed operator. The apparatus includes distribution a circuit section for variably designating the region of scanning with the ultrasonic pulse beam for the measurement of the Doppler blood flow image so that the region can be selected as desired.
摘要:
A method is disclosed for improving both the accuracy of severing electrical terminals from the chains in which they are supplied and the alignment between the terminal and the lead wire which is attached to the terminal. In both cases, alignment marks are formed on the terminal at locations delimiting the maximum ranges of positions for respective transitional edges of the cutting die used to separate the terminals and the insulation-stripped end of the lead wire. The terminal is aligned with the die and the lead wire using these marks prior to cutting and crimping of the wire.

A high-strength steel for valve springs, consisting of 0.50-0.70 wt. % of carbon, 1.50-2.50 wt. % of silicon, 0.50-1.20 wt. % of manganese, 1.50-2.50 wt. % of nickel, 0.50-1.00 wt. % of chromium, 0.20.0.50 wt. % of molybdenum, 0.15-0.25 wt. % of vanadium, and the balance being iron and inevitably included inclusions. Also disclosed is a process for producing such a high-strength steel, which includes a step of minimizing oxygen in a melt of the steel, so as to reduce the oxygen content of the steel to 15 ppm or less, and a step of adding calcium to the melt and thereby controlling the form of the inclusions. The process may further include a step of minimizing titanium and nitrogen in the melt, so as to reduce the titanium and nitrogen content of the steel to 50 ppm or less, and 60 ppm or less, respectively.

摘要:
A head shift mechanism in a magnetic tape apparatus includes a rotatably driven gear, a movably supported engaging member intermittently engageable with the gear, and a cam member which is operatively coupled to and moves simultaneously with the engaging member. A movably supported changeover member is cooperable with and moves in response to movement of the cam member, and a selectively actuable arrangement causes the gear to drivingly engage the engaging member. A movably supported operating member has a magnetic head thereon, and the changeover member can cause a movably supported control member to move the operating member to an advanced position. A lock arrangement is provided to releasably lock the control member in a position where it holds the operating member in the advanced position, and selectively actuable release arrangement is provided for releasing the lock arrangement.
摘要:
A magnetic recording/reproducing apparatus in a tape player comprising a rotatable cam and an operational means interlocking with the rotatable cam. The operational means is arranged to operate a control means for forwardly and rearwardly moving reproduction mechanisms like a head, a pinch roller or an idler and the control means is to be held in its reproduction position by a locking means.
