Title: Heat treatment of bi12geo20 single crystal
Inventor: YAMAZAKI TORU
IPC: C30B33/00
Filed: 1988-02-29
Abstract: PURPOSE:To obtain single crystal free from generation of a crack in a heat- treating process and a working process of crystal by heating Bi12GeO20 single crystal at specified temp. CONSTITUTION:Bi12GeO20 single crystal is heated in a range within 700-780 deg.C. This heat-treatment temp. is regulated to 700-780 deg.C by the following reason. In other words, in the temp. range not higher than 700 deg.C for producing a solid phase, long time is necessary for temp. holding time to remove strain in case of growing single crystal and therefore it is not practical. Further a region producing a metastable phase exists in the temp. range not lower than 780 deg.C and when heat treatment passing through this region is performed, strain due to deviation of composition in the fine region remaining in crystal is increased and a crack is generated in the working process.

Abstract: PURPOSE: To remarkably lower the spread of the line aberration by inserting evenly distributed projected parts into a coiling space in a coiling process and giving re-setting point for next coil turns. CONSTITUTION: During a coiling process, an inside coil section 27 is wound on a core rod and when the number of the turns reaches the necessary value in the section 27, pins 37 positioned respectively at right angles to the face of the turns and symmetrically relative to the vertical axis of the turns are immediately inserted into a coiling space part. Then, an initial turn of the next section 29 is positioned in the surrounding of the pins 37 and a gap 23 is formed in side part 21 between the sections 27, 29. Next, when the number of the turns reaches the necessary value in the second section 29, two or more pins (projected parts) 39 are inserted into the coiling space and four gaps 25 are formed by arranging the turns. In this manner, re-setting is carried out at these four points in the part 21 and the spread of the line aberration can be lowered by 50%.

Title: High pressure injection tubing for diesel engine
Inventor: UEMITSU ISAO
IPC: F02B3/06
Filed: 1989-02-28
Abstract: PURPOSE:To control the spike type vibration pressure of a high pressure fuel injection tubing by coaxially arranging an inner pipe and an outer pipe, concurrently interposing resin into a space between the inner pipe and the outer pipe, and thereby elastically deforming resin against the pressure vibration at the inner pipe side. CONSTITUTION:A high pressure injection tubing 18 has an inner pipe 20 and an outer pipe 22 arranged in such a way as to be at the inner side and the outer side respectively with respect to the radial direction, and also concurrently has them coaxially extended mutually so as to be formed. In this case, resin 24 thinner than the wall thickness of the inner and outer pipes is coaxially interposed radially in a space between the inner pipe 20 and the outer pipe 22. The tip section A of the high pressure fuel injection tubing 18 is squeezed so that resin 24 is fixed onto the inner pipe 20 and the outer pipe 22 respectively. Then, resin 24 is adapted to be elastically deformed against pressure vibration accompanied with high pressure fuel injection at the inner pipe 20 side. This permits the elastic deformation to absorb spike type vibration pressure at the inner pipe 20 side, thereby controlling the spike type vibration pressure of the high pressure injection tubing 18.

Abstract: PURPOSE:To detect positioning well only with rotary heads in a recording and reproducing device of a PCM signal by making the frequency of a positioning pilot signal in a recording position, which should be positioned at a reproducing time, different from that in other parts at a recording time. CONSTITUTION:The device is set to the quick traversing or rewinding reproducing mode simultaneously with turning-on of a positioning switch. At this time, a pilot signal P1 or P2 taken out from a tape is supplied to a low pass filter 41 and is extracted and is supplied to a detecting circuit 42, and the change from the signal P1 to the signal P2 having a frequency f2 is detected. Consequently, a detection signal SD of the signal P2 is obtained from this detecting circuit 42 when the position of the signal P2 recorded between musics at a recording time is detected; and if the signal SD has a prescribed level or higher, a detection output signal is led out to an output terminal 44, and the tape is set to the normal reproducing mode from the quick traversing or rewinding mode in the position to be positioned by the output signal. Thus, positioning is performed only with rotary heads.

Filed: 1979-04-16
Abstract: PURPOSE: To improve accuracy, responsiveness and reliability and make manufacture easy by so constructing the apparatus that a thermocouple is pressed to the heat receiving element by means of a fine steel pipe.  
     CONSTITUTION: A heat receiving element 2 of sufficiently small spherical form to take best advantage of the responsiveness of a thermocouple 3 is installed to a heat receiving element stanchion 5 of good thermal insulation characteristic. Also, the thermocouple 3 is installed by being directly pressed to the heat receiving element 2 by a fine steel pipe 4 without welding. Since the heat receiving element 2 is made in sufficiently small spherical form, the decrease in measurement accuracy owing to thermal deformation and the decrease in apparatus life owing to thermal stress are small. Further, the heat receiving element 2 is moved by a screw mechanism and therefore the position of the heat receiving element 2 may be set with good accuracy.

Abstract: PURPOSE:To prevent the low temp. cracking after hot working quickly and surely through simple operation by cooling a martensitic stainless steel under specific conditions from high temp. and reheating the same then cooling it down to ordinary temp. thereby softening the steel. CONSTITUTION:A martensitic stainless steel is cooled from the high temp. state after hot working down to the temp. region wherein the upper limit is Ms point + 100 deg.C and the lower limit is the higher of Mf point or 100 deg.C, at the cooling rates at which it is not cooled down to the nose of the pearlite transformation. Thence, it is reheated to the temp. below the Ac1 point and is held at this temp. for >=1min to temper the transformed martensite or the residual austenite is converted to pearlite, whereby the residual austenite is converted to low carbon. Next, the steel is cooled down to ordinary temp. so that the transformed martensite of high Ms point is softened by self-tempering. By this method, low temp. cracking is suppressed and the products of the martensitic stainless steel are mass-produced in good yields.
