Title: Production of metallic titanium
Inventor: OKUDAIRA SHIGENORI
IPC: C22B34/12
Filed: 1992-05-14
Abstract: PURPOSE:To efficiently maintain the temp. in a reaction area and to decrease the quantity of heat extraction in the case of formation of the metallic titanium by maintaining the temp. in the reaction area at the temp. above the m.p. of the metallic titanium by a high-frequency induction heating means. CONSTITUTION:A reaction vessel 1 having the high-frequency induction heating means and vessel wall cooling means in correspondence to the reaction area is used. The metallic titanium is charged into this reaction vessel 1 and its peak part is arranged to correspond to the reaction area. The inside of the reaction vessel 1 is maintained in an inert gaseous atmosphere. In addition, the wall of the reaction vessel 1 is cooled and the reaction area is heated by the high-frequency induction heating means to maintain the temp. of the area at above the m.p. of the metal titanium. Titanium tetrachloride and a reducing agent metal are supplied to the reaction area and are brought into reaction in the state of melting the peak part of the metal titanium corresponding to the reaction area to form the metal titanium. The metal titanium is fused into a molten bath. The byproduced metal chloride of the reducing agent is made to flow down along the inside wall of the vessel wall and is discharged in a liquid state to the outside of the system. While the formed metal titanium is cooled to solidify, the metal titanium is continuously extracted as the metal titanium ingot to the outside of the system.

Title: Poppet valve drive system
Inventor: YONEKUBO YOSHIHARU
IPC: F16K47/00
Filed: 1984-07-17
Abstract: PURPOSE:To prevent seating of poppet valve onto the valve seat with shock by temporarily interrupting supply of working fluid to the pressure chamber. CONSTITUTION:When the groove section 18 is located lower than the fluid path 15 and the discharge path 19, the working liquid is fed only to the supply system for the pressure chamber 8 thus to energize the poppet valve 3 in the closing direction. Upon motion of the groove section 18 to the position communicatable with said paths 15, 19, the working liquid in said path 15 is fed through the groove section 18 to said path 19 thus to considerably reduce the pressure of fluid to be fed to the pressure chamber 8 and to lose the energizing force in the closing direction. Consequently, the poppet valve 3 can be seated gradually on the valve seat 9.

Filed: 1983-08-11
Abstract: PURPOSE:To attain color separation without complicated constitution by separating a picture signal outputted by changing the spectral distribution of a light spot on an information source to be picked up regularly attended with the scanning of the light spot into a color signal based on the regular change of the spectral distribution. CONSTITUTION:When a band of each color is scanned in a frequency f1 in order to obtain a picture signal from an object 5 such as a photo film, the color of the light transmitting through a color filter 3 is changed in the frequency of f1 and corresponds to the 1st color band transmission characteristic A1(lambda) and the 2nd color band transmission characteristic A2(lambda). The color characteristic of the light projected on the object 5 has the color difference component of A0(lambda).A1-2(lambda) modulated in the frequency f1 around the average color A0(lambda).A1+2(lambda). Two signal components are separated and two color signals are obtained by outputting a picture signal S0 to, e.g., a band pass filter 26 having a center frequency f1, a detection circuit 27, a delay circuit 24 and a low pass filter 25. In order to three color signals for the reproduction of natural color, another stripe color filter is overlapped.

Title: Laser machining apparatus
Inventor: NEI MASAHIRO
IPC: H01S3/00
Filed: 1985-07-05
Abstract: PURPOSE:To implement low power consumption and a long life without impairing stability in output, by estimating the possible machining start time of a machining laser, and starting oscillation of laser before specified time based on the estimated time. CONSTITUTION:When a machining apparatus is started, a control device 9 computes an alignment time T1 for aligning a wafer 5 to a position, where the wafer can be machined with a laser beam 1a, based on a signal from a measuring device 7. A sufficient time T2 for stabilizing the output after the start of oscillation of a machining laser 1 is subtracted from the time T1. Whether the time difference T3 is larger than zero or not is judged. When, the time T3>0, the oscillation of the laser 1 is started after the time T3 from the start of the alignment of a stage device 6. The device 6 is stopped after the time T1, and the machining is started. When the time T3<=0, the laser 1 is oscillated, the device 6 is stopped after the time T1 and the machining is started. This procedure is repeated for a plurality of the wafers.

The differential speed is generated between the rotation of outer holding member 9 press-fitted to the sub-gear 8 and that of a rotational shaft 1. The member 9 is relatively roteted on a right direction until the left-side surface of a cutout 11 of the member 9 abuts against a stopper 1a. A sprag 6 housed in a pocket 9a of the member 9 is fallen in the rotational direction of the member 9, the outer and inner diameter side arcuate surfaces are engaged with opposing cylindrical surfaces 17, 18.

Title: Color recording method
Inventor: MORITA HIDEKI
IPC: H04N1/40
Filed: 1983-08-12
Abstract: PURPOSE:To obtain a gradation color picture without uneven density by gradation expressing either one of a yellow picture and a magenta picture by means of a matrix pattern belonging to a mesh form and the other by means of a matrix pattern belonging to a vortex form. CONSTITUTION:The gradation of the yellow picture Y is expressed by the vortex form matrix pattern and the gradation of the magenta picture M is expressed by the mesh point form matrix pattern to overlap both patterns. As clearly indicated in Figs. (a) and (b), there is a tendency between both patterns that the half of dots are overlapped but the remaining half dots are not overlapped independently of the degree of a shift. Thus, even if some degree of carrying error is produced at the carrying of a recording paper sheet, the conventional uneven density is not caused and a gradation color picture with high guality is obtained.

Title: Control device for four-wheel-drive speed change gear
Inventor: HAYAKAWA YOICHI
IPC: B60K23/08
Filed: 1984-07-17
Abstract: PURPOSE:To make it possible to eliminate a manual change-over operation from a two- wheel-drive condition to a four-wheel-drive condition by a driver, by enabling the change-over operation from the two-wheel-drive condition to the four-wheel-drive condition to be automatically carried out when any racing condition occures on the drive side during two-wheel-drive running. CONSTITUTION:An electronic control device 500 which automatically changes over the running condition of a vehicle from a two-drive-wheel condition to a four-wheel-drive condition in accordance with the running condition of the vehicle, is composed of an output shaft rotational speed sensor 510 for detecting the rotational speed of a speed meter driven gear 402, an actual vehicle speed detecting sensor 520 such as, for example, a Doppler radar for detecting an actual vehicle speed, an input/output port for receiving the outputs of both sensors and for delivering an output signal to a switch circuit 540, a comparator circuit 530 consisting of a CPU, a RAM and a ROM and the above-mentioned switch circuit 540. If any wheel on the drive side slips when the two- wheel-drive condition is selected through a manual change-over switch 550, the difference between an vehicle speed detected by the output shaft rotational speed sensor 510 and an actual vehicle speed detected by the actual vehicle speed sensor 520 exceeds a predetermined value, and therefore, the switch circuit 540 is energized to engage a clutch, thereby the four-wheel-drive condition is turned to be effective.
