Abstract: PURPOSE:To improve the abrasion resistance and thermal cracking resistance of the shaft and sleeve of the roll for the electromagnetic stirrer by limiting the specific components of austenite base heat-resisting steel. CONSTITUTION:The heat-resisting steel composed of at least one of Mo; 0.6-20%, Ti; 1.5-27%, Nb; 1.0 or under V; 0.8% or under, Al; 0.6%, or under B; 0.03% or under and the rest substantially of Fe for the basic components composed of C; 0.15% or under, Si; 1.5% or under, Mn; 3.0% or under, Ni 21-30% or under, Cr; 12-18% based on weight is used for the shaft and sleeve material of the non- magnetic roll of the electromagnetic stirrer for preventing segregation of the slab being continuously cast. The shaft and the sleeve member outside the shaft are removably provided. Here, the reason for limination of the components lies in the enhacement of high temperature strength through addition of at least one of Ti, Al, Nb. Besides, addition of at least one of Mo, V, B for the purpose of improving the high temperature strength characteristics is equally well.

Title: Device and method for recording optical disk
Inventor: OKUBO SHUICHI
IPC: G11B7/00
Filed: 1995-05-29
Abstract: PURPOSE: To provide device and method for recording an optical disk using an optical information recording medium that a reflectance of a recording film or an optical phase is changed according to light irradiation and capable of simultaneously processing recording operation and verification by a single light spot. CONSTITUTION: Laser beam of a prescribed intensity outgoing from a laser beam source 1 is converted into parallel beam by a lens 2 to be focused on a phase transition optical disk 5 through a beam splitter 3 and a condenser lens 4. The data are recorded by recording power PW at a recording time. Logical values of a various size relation between a return beam quantity output from the disk and reference voltages CLV, CTV are taken by comparators 10, 11 at a recording operation time. By ANDing between the logical values and a gate signal 53 corresponding to a rise part of a recording signal and the gate signal 52 corresponding to the fall part of the recording signal, the verification is performed. By performing the verification while performing recording by the single beam spot, the time required for recording is shortened.

Title: Burner
Inventor: KATO HIROHISA
IPC: F23M20/00
Filed: 1995-05-29
Abstract: PURPOSE: To prevent the pulsating combustion by forming an acoustic space having an acoustic natural frequency, so disposing a suction tube and an exhaust tube as not to be affected by the influence of the frequency, and providing a sound absorber for absorbing the sound having a natural frequency in the space. CONSTITUTION: An inlet buffer chamber 280 becomes a mere space, and a pulsating combustion occurs at the time of combustion. The pulsating combustion is the vibration of acoustically closing the inlet reflecting surface 330 and outlet reflecting surface 220 of the lower part of the chamber 280. When the pulsating combustion occurs, the pressure change of single frequency is detected in a burner, and the noise of the same frequency is detected out of a combustion chamber 180. Then, when a sound absorber 340 for absorbing the pulsating frequency is filled in the chamber 280, no pulsation occurs. Even if the lengths of an air supply tube 101 and an exhaust tube 105 are varied in a predetermined range, no pulsation occurs. That is, the lengths of the tubes 101 and 105 do not affect the pulsating combustion.  Since the higher the sound absorbing effect of the sound absorbing material is, the larger the sound absorbing effect is, the generating pulsation is better at higher frequency.

Title: Picture image processor
Inventor: OKI KOUJI
IPC: G06T5/00
Filed: 1984-06-25
Abstract: PURPOSE:To eliminate the effects of picture image noises and to recognize a defect with high accuracy by comparing the difference of density between two adjacent area in the direction crossing the edge direction of plural picture elements with a prescribed discrimination level. CONSTITUTION:A differenitiating circuit 8 obtains the edge value corresponding to the difference of density between edges of a picture image and the extending directions of edges and stores them to a memory 9. At the same time, the edge linen is thinned to a line of a single picture element through a line thinning circuit 10 and stored to a frame memory 12 after the threshold value processing. Then the edge direction of the picture element is read out of the memory 9, and the difference of density is calculated between areas E1 and E2 crossing said edge direction. This calculated difference of density is compared with a prescribed discrimination level. If a large difference is obtained from this comparison, the flags are set up at a buffer repetitively until no picture element is detected. Thus it is decided that a matter to be checked has a defect if the flag has the larger value than the prescribed value.

Title: Expansion pipe for ventilation
Inventor: NISHIMURA TETSUZO
IPC: F16L5/00
Filed: 1991-05-01
Abstract: PURPOSE:To enable freely adjusting the extent of an insertion into a main pipe and the extent to which the insertion can be pulled back by using a discontinuous wedge ring whose breadth in the radial direction first waxes, starting with a fastening claw, and then wanes and whose outer peripheral edge is brought in tight contact with the inner surface of the main pipe under pressure of elastic radially expansive force. CONSTITUTION:A discontinuous wedge ring 18 having radial elastic force is fitted in a circumferential groove 17 in an adjusting tube 11. One end of the wedge ring 18, that is, at the broken part 20 in the ring 18, is formed into a fastening claw 19 which is caught by a projection 15 formed in the circumferential groove 17. The breadth of the wedge ring 18 in the radial direction first waxes, starting with the fastening claw 19, and then wanes toward the other end 18b. To fit these together, the adjusting tube 11 is inserted into a main pipe 10 and turned in the direction shown by an arrow of broken line so as to lock the fastening claw 19 of the wedge ring 18 with the projection 15 in the groove 17; then the wedge ring 18 now having its fastening claw 19 locked with the projection 15 also turns jointly, overcoming the frictional resistance from the inner surface of the main pipe 10. This enables the adjusting tube 11 to be moved in the axial direction and makes it possible to freely adjust the extent of the insertion in the main pipe 10 and the extent to which the insertion is drawn back.

Title: Manufacture of semiconductor device
Inventor: SAKAMOTO HIROAKI
IPC: H01L21/22
Filed: 1986-06-07
Abstract: PURPOSE:To shorten the period of time taken for a high-temperature thermal treatment process and to lower the manufacturing cost of a semiconductor device, by performing various thermal treatment steps at the same time. CONSTITUTION:Impurities for providing opposite types of conductivity (PB, PE) are deposited shallowly from the opposite principal faces of an N-type silicon substrate 1. An impurity for providing the same conductivity type as the N-type silicon substrate is selectively deposited on one of the principal faces of the N-type silicon substrate 1 such that its conductivity-type is inversed to the same conductivity type (N<+>) as the Ntype silicon substrate in the conductive layer having the shallowly deposited impurity. Subsequently, a thermal diffusion treatment is conducted such that a diffused region has a predetermined depth. Though a thermal treatment process generally takes a very long period of time, only one such process is required according to the method of the invention and, therefore, the time required for the thermal treatment process can be shortened substantially.
