Abstract: PROBLEM TO BE SOLVED: To obtain a polishing material, a cutting material and a sliding material requiring a high hardness by jetting particles of a hard material together with a fluid to an applied body by shock acceleration so as to perform spray adhesion of the hard material to the applied body. SOLUTION: A high hardness material such as diamond is jetted to an applied body 11 by shock acceleration by means of a shock compression application device so as to be spray-applied onto the applied body 11. The shock compression application device has a cylindrical double structure. That is, the shock compression application device comprises a sample chamber 3 at its center part accommodating a hard material and a fluid, a space 6 around a periphery part of the sample chamber 3, a flight plate 7 and a gunpowder filling part 8, disposed in this order, while the applied body 11 is disposed opposite to a lower nozzle 10. The shock compression application device is also provided with a fluid supplying part 9.  As the fluid, an inert gas such as nitrogen is used, An explosion of the gunpowder in the gunpowder filling part 8 causes shock pressure of the flight plate 7 to the sample chamber 3 so as to compress the sample chamber 3. As a result, particles of the hard material accelerated by the shock wave together with the fluid are jetted to the applied body.

IPC: H01L21/66
Filed: 1984-12-26
Abstract: PURPOSE:To provide a temp. variable cryostat capable of changing the temp. of an electronic element continuously from the temp. of a cooling medium to room temp., by linearily changing the temp. distribution in a test chamber by utilizing the heat conductivity of a support conductor. CONSTITUTION:When the temp. of a high temp. part is set by a heater 21, the heat of the heater 21 propagates through a support conductor 12 to enter a cooling medium container 8. The temp. of the lower part of the support conductor 12 at this time is the b.p. of a cooling medium 8 same to the temp. of the upper plate 9 of the cooling medium container 8 and the temp. of the upper part of the support conductor 12 same to that of the flange of a vacuum container 10. The temp. distribution of the support conductor 12 is one obtained by linearily connecting the temps. at the upper and lower parts of the support conductor 12. Because the temp. of helium gas in a specimen chamber becomes almost equal to the wall temp. of the support conductor 12, the temp. distribution in the specimen chamber 17 also linearily changes. Therefore, when the temp. of an article 1 to be measured is desired to be set to arbitrary temp., the height of the specimen chamber may be changed by driving a motor 4.

Abstract: PROBLEM TO BE SOLVED: To attain power saving, to prevent blackening, and to prolong lamp life by inserting a current-limiting element between an inverter circuit and a discharge lamp and by providing a dc voltage superimposing means on the filament side. SOLUTION: When a commercially available alternator Vs is inputted, a rectification smoothing circuit 2 generates and outputs dc voltage to an inverter circuit 3. The inverter circuit 3 converts the dc voltage to high frequency voltage and applies preheating voltage between filaments 5a and 5b of a discharge lamp 5. A dc voltage superimposing means 4 applies a negative polar dc voltage on the filament 5a. Dc voltage from the dc voltage superimposing means 4 is applied between the filaments 5a and 5b with superimposing the preheating voltage outputted from the inverter circuit 3. The filament 5a is sufficiently preheated by the superimposed applied voltage so that the filament 5a can easily emit electrons. When the inverter circuit 3 applies a starting voltage that dc is superimposed between the filaments 5a and 5b of the discharge lamp 5, discharge is formed.

CONSTITUTION:Up to the time tF when the open fault occurs in a capacitor 51, magnetic flux is changed in a current transformer 70 with polarities for offsetting ripple currents IR1 and IR2, and the secondary output of the current transformer 70 is zero. After the time tF, the current IR1 becomes approximately zero, and the secondary output IRDET corresponding to the current IR2 generates the abnormal voltage. The voltage becomes the abnormal signal VDET through a rectifying circuit 73. The signal is compared 22 with a voltage judging level VLEB through resistors 33 and 34. The signals becomes a wavefor-shaped signal V2 through an inverted logic gate circuit 154. After the abnormality has occurred, the sequence of 0 1   0   1 is repeated until the apparatus is stopped. The signal V2 sets a flip-flop 152 through an AND logic circuit 151 which does not accept interlocking. A fault signal FAULT is changed from 0 to 1, and the apparatus is stopped for protection.

Title: Field discrimination circuit

IPC: G09G5/18
Filed: 1988-10-28
Abstract: PURPOSE:To prevent field discrimination malfunction and unstable operation by using a stable vertical synchronizing signal after the selection independently of the timing of an input vertical synchronizing signal. CONSTITUTION:Even if vertical synchronizing signals Va-Vf are inputted in any timing, the vertical synchronizing signal inputted in the middle of signals HF0-HF2 at all times is selected among 6 vertical synchronizing signals shifted by a shift register 11. Thus, the stable interlacing is applied. On the other hand, in order to recognize accurately whether the received signal is interlaced or noninterlaced, it is required to split one horizontal scanning period into at least 6 or over. That is, in the case of considering the occurrence of malfunction by + or -1 in advance, in total 6 divisions or over are required as split =3 for noninterlace and split =3 for interlacing. Thus, malfunction or unstable operation is solved.
