Title: Production of nitrophenylphenylsulfones
Inventor: ONOE AKIRA
IPC: C07C313/00
Filed: 1987-08-05
Abstract: PURPOSE:To obtain the titled compound useful as a producing intermediate for benzene sulfinic acid alkali metal salt advantageously on an industrial scale in high yield and purity, by oxidizing nitrophenylphenyl sulfides with hydrogen peroxide in the presence of a specific catalyst. CONSTITUTION:Compounds expressed by formula I (n is 1 or 2) are oxidized with H2O2 in a heterogeneous two phase based solvent in the presence of a catalyst (e.g. ammonium tungstate or sodium tungstate) selected from tungstate and molybdate and phase-transfer catalyst (e.g. chlorotetramethyl ammonium) to provide the aimed nitrophenylphenyl sulfones expressed by formula II. The above-mentioned two phase based solvent includes e.g. hexane, heptane or benzene. The above-mentioned method is preferably used in oxidizing nitrophenyl- phenyl sulfides produced as by-product and circulating the oxidized product as a raw material.

Title: Apparatus for production of optical disk
Inventor: SUZUKI KOJI
IPC: B29D17/00
Filed: 1993-07-14
Abstract: PURPOSE:To suppress the generation of resin scrap and to produce the optical disk having stable quality as there is no flow-in of a photosetting resin by facilitating peeling of even the disk having a large diameter and having poor flexibility, such as glass in particular. CONSTITUTION:A center block 14 pushes up an inner peripheral part 20a of a disk substrate 20 and a center pin 15 pushes up a slope 290b at the inner peripheral edge of this disk substrate 20 and, therefore, the peeling of the optical disk from a stamper 12 is easy. This center block 14 is formed with a slope 14b on the surface existing in the upper part of the hole for guiding the center block 14 and is interposed with the inner peripheral part 12a of the stamper 12 between this slope 14b and an electromagnetic magnet base 11 and, therefore, the slope 14b and the stamper 12 are in tight contact with each other. The surface 15a of the center block 15 in contact with the slope 20b of the disk substrate 20 is so inclined as to face the slope 20b.

Title: Elevator having illumination effect
Inventor: NOMURA YOSHIHARU
IPC: B66B1/06
Filed: 1993-08-06
Abstract: PURPOSE:To improve the illumination effect by varying the brightness of the illumination, in proportion to the shift speed of an elevator for view. CONSTITUTION:When a motor 1 for raising and lowering a car 5 is driven, the electric power source for the illumination lighting is generated by a generator device 2 which is directly connected with the motor 1. Further, the signal supplied from an external light sensor 6 is inputted into a control panel 7 through a signal line 8, and the ON/OFF control for an illumination lamp is carried out. Since the power generation quantity at this time is proportional to the traveling speed of an elevator, i.e., the revolution speed of the elevator driving motor, the illumination lamp put ON by the electric power becomes proportional to the traveling speed of the elevator, and brightness can be changed.

Title: Sputtering device
Inventor: ARAI SUSUMU
IPC: C23C14/56
Filed: 1995-07-07
Abstract: PROBLEM TO BE SOLVED: To enable cleaning in a sputtering chamber and the exchange of a target without opening the sputtering chamber into the air by isolating a magnet from a backing cover and detaching the backing plate integrated to the target from the backing cover. SOLUTION: A magnet 71 is arranged on the air side of a backing cover 56. In the case a target T is made of a nonmagnetic body, an iron sheet 14 as a magnetic body is burried in a backing plate 11, and in the case the target T is made of a magnetic body, it is not burried. Then, the magnet 71 is drawn near the backing plate 56 by using a vertical mechanism 73 or is isolated therefrom, by which the backing plate 11 integrated to the target T is fixed to the backing cover 56 by magnetic force or is detached from the backing cover 56 in a sputtering chamber 51 in a vacuum. Thus, the working rate of the sputtering device can remarkably be improved.

Title: Minute force detector
Inventor: FUJII TORU
IPC: G01B11/30
Filed: 1990-07-26
Abstract: PURPOSE:To allow the positioning, regulating work by optically microscopic observation by detecting a light quantity change of light by deflection of a light guided wave accompanied by displacement of a force detecting cantilever, and converting it to an electric signal. CONSTITUTION:The optical beam emitted from a light source 12 is guided to a light waveguide path 7 by an optical fiber 10 to scan the surface of a material to be measured by a contact needle 6. When the contact needle 6 is ultimately approached to the surface of the material to be measured 4 to bring the electron cloud of the atom on the surface into contact with the electron cloud of the atom on the top of the contact needle 6, a repulsive interatomic force is generated between them, whereby a force detecting cantilever 5 on which the contact needle 6 is mounted is deflected. In accordance with this, the waveguide path 7 is also deflected, and its impedance is changed. The emitted light quantity of the light advancing in the waveguide path 7 is changed, and this is detected by a light detecting part 13, whereby the displacement quantity of the lever 5 can be known.
