Title: Optical recording medium
Inventor: OMICHI TAKAHIRO
IPC: G11B7/244
Filed: 1987-02-17
Abstract: PURPOSE:To obtain a high-sensitivity, nontoxic and stable optical recording medium capable of being produced through a simple coating process and capable of recording with a small-type semiconductor laser, by providing a recording layer in which a magnesium-phthalocyanine associate having a specified maximum absorption wavelength is dispersed in a polymer matrix. CONSTITUTION:An optical recording medium is produced by providing on a substrate 2 a thin film 1 in which a phthalocyanine associate having a maximum absorption wavelength of 800-850nm is dispersed in a polymer matrix. The thin film can be easily provided by applying a solution containing magnesium- phthalocyanine and a polymer to the substrate. The polymer may suitably be polymethyl (meth)acrylate, a styrene polymer, polyvinyl chloride or the like. A solvent to be used may be any one capable of dissolving both magnesium- phthalocyanine and the polymer, and may suitably be a halogen-containing solvent such as chloroform. The coat film thus obtained is treated with a halogen-containing solvent, for conversion into the phthalocyanine associate having a maximum absorption wavelength (lambdamax) of 800-850nm.

Title: Copper wiring in semiconductor devices
Inventor: TAGUCHI MITSURU
IPC: H01L21/28
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a structure for copper wiring in semiconductor devices, with which failures caused by peeling off of the wired copper, and reliability degradation of the wiring and the like, are prevented. SOLUTION: As an undercoat for copper wiring 23, a titanium nitride film 21 is formed, wherein the film is a nitrogen interstitial solid solution, which features excellent adhesion to copper, effective barrier against copper, and low reactivity with copper. As an embodiment, a titanium film 20 and a titanium nitride film 21 of a nitrogen interstitial solid solution are stacked in this order on inside wall of a groove 18 formed in a PE-SiO2 film 17, and copper wiring 23 is formed thereon. Because the titanium nitride film of a nitrogen interstitial solid solution is formed as an undercoat for the copper wiring 23, it is possible to minimize resistance increase of the copper wiring 23, and to obtain better adhesion to copper as compared with existing titanium nitride film that contains crystalline titanium nitride while preventing diffusion of copper into interlayer insulating film.

Title: Discharging device for disk object
Inventor: ABE HIROSHI
IPC: G07D1/00
Filed: 1997-01-10
Abstract: PROBLEM TO BE SOLVED: To prevent the medal or another shop from being used again by selecting only a proper medal and excluding the other medals while discharging disk objects such as coins or medals and judging whether each disk object is proper or not. SOLUTION: When a medal M gets closer to a detecting coil 69, the impedance of detecting coil 69 is changed and as a result, the oscillation frequency or oscillation level of oscillator is changed. This change is made different corresponding to the diameter, thickness and material of medal M as the disk object. Therefore, this change component is compared with the previously stored reference value data of proper medal so that it can be easily discriminated whether the medal M to be passed is proper or not. When many medals M are put into a head and a device is operated, the proper medal is discharged from a discharging port 55 opened at the side end of lid case 52 and the dummy medal is discharged from an excluding port 56 opened at the side center of lid case 52.

Abstract: PURPOSE:To enable control of the flow rate of an exhaust port with a large bore and to perform complete opening and complete closing, by a method wherein a sluice valve is operated in a direction extending at right angles with a vacuum exhaust direction and an exhaust direction. CONSTITUTION:A cam 34 between a valve 31 and a valve insert 33 is brought into a horizontal state, in order, from a longitudinal and an oblique state, and this separates the valve 31 from a valve support 30 and moves downward the valve 31 to open a valve. In which case, exhaust gas flows from 50 to 51 through a gap between a C washer 35 and an O-ring. Further, such flow is controlled by a gap between the C washer 35 and edges 36 and 36' of the valve support. The cam 34, the arm 38, and the plate 37 move the valve 31 in a direction, different from a flow, such as right-angled direction.

Title: Pulling up of single crystal
Inventor: OKUI MASAHIKO
IPC: C30B15/20
Filed: 1996-01-26
Abstract: PROBLEM TO BE SOLVED: To provide a method for pulling up a single crystal by which the single crystal pulled up from a melt can be cut off and quenched to thereby afford the single crystal in the absence of crystal defects [a dislocation cluster, an infrared scattering material or a flow pattern defect (FPD)] in a site at a higher temperature than that for forming the crystal defects. SOLUTION: A single crystal 9 is pulled up and grown from a melt 8 only by a prescribed length according to a Czochralski(CZ) process and the pulled up crystal 9 is then cut off from the melt 8. The cut off single crystal 9 is subsequently lifted at a high speed and quenched. The single crystal 9 is pulled up at a low speed so as to form only the outside crystal of a ring-oxidation induced stacking fault (R-OSF), cut off from the melt and quenched. Thereby, the single crystal without forming a dislocation cluster is obtained in a site quenched from a temperature region from the melting point to 950 deg.C.  The single crystal 9 is pulled up at a high speed so as to form only the inside crystal of the R-OSF, cut off from the melt and quenched to afford the single crystal without forming an infrared scattering material or a flow pattern defect in a site quenched from a temperature region from the melting point to 1,050 deg.C.

Title: Flow rate detecting device
Inventor: KITA TOORU
IPC: G01F1/28
Filed: 1981-03-09
Abstract: PURPOSE:To detect the flow rate in a broad range properly by giving drag which is balanced with fluid pressure to an elastic member which detects the iquid pressure, and detecting said drag. CONSTITUTION:When a dynamic pressure plate 1 receives the pressure by the fluid flowing in a duct, variable resistances R3 and R4 are varied in response to the amounts of deflection of strain gages 3 and 4 caused by the deflection of the elastic member 2. Unbalanced difference is generated between points P1 and P2 of a bridge circuit. Said potential difference makes a current to flow to an electromagnetic coil 9 through amplifiers 6 and 16 and a Tr 17. A magnetic core 8 attracts the elastic member 2 so as to give the balance with respect to the fluid pressure. By detecting the current flowing the electromagnetic coil 9, the flow rate in the broad range can be properly detected.

Abstract: PURPOSE:To attain viewing of a specific channel without a troublesome and complicated operation by releasing a viewing inhibit state due to a changeover switch when an inputted pass word and a predetermined number are coincident. CONSTITUTION:A changeover switch 16 inhibits viewing of a specific channel selectively and even when the operation of the changeover switch 16 is not enabled by an operation inhibit means 16b, when the pass word inputted by an input means 26 and a predetermined number are discriminated to be coincident with a comparison means 17a, an inhibit release means 17b releases the viewing inhibit state by a changeover switch. Thus, when the specific channel is viewed, it is not required to release the operation inhibit state by the operation inhibit means 16b for each occasion. Thus, the viewing of the specific channel is attained by having only to enter the pass word.
