Title: Mold member for molding optical element
Inventor: YOKOTA MASAAKI
IPC: C03B11/00
Filed: 1987-08-25
Abstract: PURPOSE:To contrive improvement in quality of products and prolongation of mold life, by forming a tantalum nitride coating layer on the cavity surface and simultaneously changing tantalum content of the coating so as to gradually increase from a specific atom.% value to the side of the cavity base metal. CONSTITUTION:A cavity base metal 30 is previously machined from a material, such as super hard alloy or sintered SiC, and the forming surface thereof is finished to a desired surface accuracy. A tantalum nitride layer 32 is then formed on the surface on the cavity surface side of the base metal 30 by a physical vapor deposition (PVD) or chemical vapor deposition (CVD) method. In the process, production condition is suitably set to provide 20-80atom.% tantalum content on the surface of the tantalum nitride layer 32 and the content is gradually increased to the side of the cavity base metal 30 and changed to 45-100atom.% on the interface from the cavity base metal 30. Since the hardness on the molding surface is increased and the joining force between the cavity base metal 30 and the coating layer 32 is strengthened, mold life is prolonged with improved product quality.

Filed: 1988-08-23
Abstract: PURPOSE:To make clamp force film and sure and clamp arm operation speedy enough by letting a connecting arm have such a function as locking the clamp arm to a clamp position upon interlocking with the vertical motion of a table spindle. CONSTITUTION:A pallet P mounted on a pallet base 15 is clamped by constant clamping force when its coupling 97 is engaged with a coupling 18 and checked of its movement in the circumferential direction and simultaneously a clamp claw 86 of a clamp arm 85 is engaged with a clamping step part 98 and presses it. At this time, this clamp arm 85 is locked to a clamp position by a connecting arm 90 being energized in a push-up direction by each action of push-up springs 37 and 60, so that such a fear that it might be moved to the clamp position unexpectedly is brought to nothing. Accordingly, clamp force is firm and sure, so that there is no trouble that the pallet P is unexpectedly floated, etc.

Title: Method for setting pressure regulator of safety value
Inventor: SANO EIJI
IPC: G01L7/00
Filed: 1990-08-09
Abstract: PURPOSE:To make it possible to set popping pressure accurately by detecting the load which is applied on a valve rod when blowoff is started, and estimating the popping pressure based on the load. CONSTITUTION:Fluid pressure (base pressure) is applied on an inlet side 12 of a safety valve 11 which is attached to a pressure container. The safety valve 11 is in the closed state. Then, a pressure gage 28 is observed, and the pressure in a cylinder is increased by the compression with a hydraulic jack 23. The load is transferred to the valve rod 15 through a connecting nut 31, a load cell 21 and an auxiliary screw rod 33. The load applied on the hydraulic jack 23 is detected with the load cell 21 as the tensile load. When the pressure in the cylinder is further increased, the valve rod 15 is pushed up, and the safety valve 11 is opened. The popping pressure is computed by using the base pressure and the load.

Abstract: PURPOSE:To obtain vinyl chloride advantageously on an industrial scale, by adding a specific amount of hexachlorocyclopentadiene as a decomposition promoting agent to a vapor obtained by partially evaporating liquid 1,2- dichloroethane in an evaporation band area under pressure. CONSTITUTION:When 1,2-dichloroethane is thermally decomposed to vinyl chloride in the presence of a decomposition promoting agent, raising of boiling point of the above-mentioned decomposition promoting agent is suppressed and the thermal decomposition reaction of the above-mentioned ethane is remarkably promoted and contact time is shortened by partially evaporating the above- mentioned liquid ethane in an evaporation band area under pressure and simultaneously adding 0.001-1wt.% hexachloropentadiene as a decomposition promoting agent to vapor of the above-mentioned ethane and thermally decomposing the above-mentioned ethane at 300-600 deg.C. Restriction to the material of the apparatus is remarkably relaxed and net working rate of the apparatus is increased, because reaction temperature can be lowered when the decomposition ratio is maintained to same level.

Title: Reflection type image projection device
Inventor: IIZUKA TAKAYUKI
IPC: G02B13/16
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To provide an image projection device capable of translating a projection range to a screen without making a moving mechanism large-sized and lowering the luminance of an image which is projected even when a reflection type modulation element is used. SOLUTION: Illumination light emitted from a light source part 2 is made incident on a turning mirror 6 through a projection lens 5, reflected on the mirror 6 and made incident on a reflection type modulation element 3 through the lens 5. The reflected light modulated according to an image by the element 3 is transmitted through the lens 5 and passed through a side where the mirror 6 is not arranged to reach a screen 4. In order to shift the projection range, the element 3 is moved in parallel within a surface orthogonally crossed to an optical axis. By making it correspond to this movement, the turning action of the mirror 6 is adjusted so that the illumination light is efficiently made incident on the moved element 3.

Title: Emitter follower circuit
Inventor: KIOKA RIYUUICHI
IPC: H03F3/34
Filed: 1983-11-09
Abstract: PURPOSE:To obtain a large output current even when an input bias current is small, and to reduce chip area by constituting a circuit whose input bias current is small by using a current mirror circuit. CONSTITUTION:The current amplification factors of transistors TR 9 and 10 are both set to beta equally and the input and output currents of the mirror circuit consisting of TRs 11 and 12 are set to IB10 equally. Then, an input bias current IB and output current I0 at an input terminal 1 and an output terminal 2 are in relation I0=beta<2>.IB, so the input bias current is one over the integral of the current amplification factor of the TRs 9 and 10 and becomes less than the input current. Further, only one base emitter voltage of a TR is necessary between the input terminal 1 and output terminal 2, and even if the potential at the input terminal 1 drops, an output waveform is hard to distort. Furthermore, the TRs 9 and 10 of an output stage are NPN type TRs, so the chip area is reduced.
