Filed: 1937-01-11
Abstract: 490,461. Compound sheet materials. LAUTOUR, F. DE. Jan. 11, 1937, No. 807. [Class 140] A sheet or board of gas-expanded rubber or rubber-like materials is faced on one or both sides with a wood-veneer or plywood board. The sheet may have embedded in it reinforcements of wire gauze, perforated metal or plain metal sheet which may be corrugated. The composite sheets may be prepared by assembling in a mould sheets of gas-impregnated partially vulcanized rubber material and sheets of wood-veneer or plywood, and, if used, reinforcing sheets and heating under pressure to complete the vulcanization and expand the gas. The rubber sheets may be softened by applying a coating of solvent naphtha or other solvent or a coating of an adhesive may be applied. As rubber-like materials, soft or hard cured rubber substitutes prepared from diolefines, isoprene polymer, 2-chlor 1-3 butadiene, rubber chloride or hydrochloride and olefine polysulphide resins may be used.

Inventor: RAYMOND-SERAILLE ANDRE
IPC: C22B9/02
Filed: 1992-04-02
Abstract: The invention relates to a process for the purification of metals and in particular aluminium by fractional distillation. The process which comprises: (a) causing progressive solidification within a volume of liquid metal which is maintained in the vicinity of its melting point in an externally heated container by immersing therein an internally cooled body; (b) collecting at the bottom of the container all of the small crystals which are formed, (c) by compacting causing sintering of the small crystals to produce large crystals; and (d) separating the purified fraction consisting of large crystals from the liquid fraction which is enriched in respect of impurities, by tilting the container; is characterized in that, to increase the purification action, the container is maintained in its tilted position to drain off the purified fraction. The invention is used in particular in the purification of aluminium where it makes it possible for example directly to reduce the amount of iron from 800 to 1 ppm.

IPC: G06F3/048
Filed: 1987-01-06
Abstract: PURPOSE:To prevent mis-operation of a touch screen by providing a control means inactivating the touch screen when a supervisory mode is set. CONSTITUTION:A touch input deciding section 12 generates a touch input data Dt representing the item operated by the touch screen 13 and outputs the touch input data Dt to an operation data generating section 14 when the operation mode is set by a mode setting signal Sm based on a display data Dd of a CRT display device 2a and a touch coordinate data Dp of the touch screen 13 provided additionally to the CRT display device 2a. Further, when the supervisory mode is set by the mode set signal Sm, the touch input deciding section 12 does not generate the touch input data Dt as above, inhibits the operation input of the touch screen 13, resulting that the touch screen 13 is inactivated. Thus, mis-operation of the touch screen is not caused at the supervision not requiring to operate the plant and the state of the plant operation/supervision is identified clearly.

Abstract: PROBLEM TO BE SOLVED: To balance the rise time and fall time of a device and enable a number of contacts, by causing at least a group of first metal wiring tracks or a group of second metal wiring tracks to have various pitches among the group. SOLUTION: An m1 wiring track 35 and an m2 wiring track 33 are designed at a variable pitch, and different design rules are applied to regions of different gate array cells. A power-supply bus is provided along a lateral edge opposite to one vertically extending lateral edge of the gate array cell. The power-supply bus is formed in a first metal layer, and a powersupply connection line formed in a second metal layer is horizontally extended between the first metal layers. A P-type device and an N-type device are connected to the power-supply connection line. Thus, the effective resistance on the side of a diffusion region is lowered and reliability with respect to the power-supply line is improved. Also, concentration of gate cells may be reduced by providing a number of contacts with respect to source and drain.

Title: Torque sensor and its manufacture
Inventor: SUNAHATA MUTSUMI
IPC: G01L3/10
Filed: 1997-01-07
Abstract: PROBLEM TO BE SOLVED: To obtain a torque sensor in which a change in a zero point is suppressed to be small and which obtains a good sensor characteristic by a method wherein a high-frequency quenching and tempering treatment is executed to a worked part at a knurled groove. SOLUTION: When a high-frequency quenching and tempering treatment is executed to a sensor shaft 1 and, especially, to magnetically anisotropic parts 2A, 2B, a hardened layer is formed. The surface hardness of the hardened layer is at an Hv 400 to 600, and a hardening depth amounts to 2.5 to 3.5mm when the shaft diameter of a sensor shaft is, e.g. 13.7mm. Then, the hardened layer becomes a martensite texture whose surface texture is stable as different from a carbonization protective layer formed in a carburizing treatment. As a result, its uniform hardness is obtained in regions of groove parts at the magnetically anisotropic parts 2A, 2B, the hardened layer which is thick is obtained, and a good sensor characteristic can be obtained. Even when especially a torque which is larger than a rated torque is applied, a change in a zero point can be suppressed to be small.

Abstract: PURPOSE:To enable to perform heating or cooking both in the daytime and at night by a method wherein a heat medium is circulated between a solar heat collector and a heat-accumulating tank and heated, and the heated medium is circulated into a radiating part for heating. CONSTITUTION:When the first pump 16 is operated, oil 11 in the heat-accumulating tank 9 is passed through a connecting pipe 14 into a heat-collecting part 4 of the heat collector 1, where the oil 11 is heated to a high temperature and is then returned to the tank 9 through a pipe 15. When rice cooking or boiling is conducted by using a rice cooker 17, the second pump 24 is operated so that the oil being heated at the heat-collecting part 4 and returned is fed to a heat-exchanging pipe 20 of the cooker 17 through a connecting pipe 22, thereby heating the material to be cooked which is placed in a pot. The operation of the pump 16 is stopped at night. When the rice cooker 17 is used at night, a pump 24 is operated in a similar manner so that the oil 11 in the tank 9 is pumped up and circulated in the pipe 20, thereby heating the pot.

Title: Pulse-duration modulation type inverter device
Inventor: ISHIMARU KEIZO
IPC: H02M7/48
Filed: 1989-01-05
Abstract: PURPOSE:To prevent the unstable phenomenon of a load by judging that the operation of the load is in an unstable state when distortion of an output voltage waveform produces a difference in load current peak and regulating modulation frequency according to the difference. CONSTITUTION:When an induction motor 14 falls into an unstable state, the amplitude of the wave of a load current detected by a current detector 19 is uneven and differences between the current peaks in each period of said wave are comparatively great. Then the peak iI in period I is stored in the peak memory circuit 22 of a discriminator 20 and the peak iII in period II is stored into a peak memory circuit 23, therefore, a distortion detection signal is sent from a comparison circuit 24 when the ratio of the peaks iI/iII exceeds the fixed value. As a result of it, a modulation frequency regulator 25 decreases modulation frequency in a PWM signal generation circuit 15 by the fixed value repeatedly until no distortion detection signal is transmitted.

Title: Bus error detecting system
Inventor: YAMAUCHI MAKOTO
IPC: G06F11/00
Filed: 1987-01-06
Abstract: PURPOSE:To easily and accurately demarcate a faulty part at the time of occurrence of a bus error by detecting the bus error by an information processor using a bus and allowing at least another information processor not using the bus to detect the error. CONSTITUTION:In formation processor 1-4 and an information processor 5 with a means for always detecting bus error transmit and receive an address command and data via a common bussignal group 10 on the common bus. By using a bus using signal 11 on the common bus, when each information processing unit uses the bus, the unit using the bus informs the fact that the bus is in use at present and cannot by used to the other information processor. The information processor 5 with a means for always detecting bus errors which receive the bus using signal 11 detects the error of the bus even at the time of bus transfer independently of its own unit. Thus, the fault part is demarcated easily and accurately at the time of occurrence of bus error.
