To discriminate optically between the various phases in a three-phase fluid, a light beam (F) of non-zero divergence is injected into a detector block (10) made of amaterial whose refractive index is greater than the refractive indices of all three phases of the fluid. The block ( 10) has a sensitive zone (18) and a total reflection zone (20) such that incident rays (Ri) parallel to the axis (12) ...

A resin composition curable through a Michael reaction between (a) a component having a plurality of .alpha.,.beta.-unsaturate carbonyl groups and (b) a component having a plurality of activated methylene group in the presence of a catalyst is disclosed. The activated methylene component is a polymer of an asymmetric malonate ester in which one of carboxyl groups is esterified with an alkanol whil...

Object To provide control apparatuses for electric cars that can effectively limit the operation of a vehicle with a large movement such as an electric motor bicycle in a predetermined state. Configuration When a take-a-seat detecting means 2 verifies that the driver has taken a seat and an accelerator-opening detecting means 3 detects an accelerator opening equal to a minimum value, a motor-drivi...

A method of testing the memory cell contents of a program memory is proposed. A checksum, which corresponds to the sum of all memory cell contents of the program memory, is stored in a separate memory cell. At the start of computer operation, or during it, a test routine, which adds all the memory cell contents to the existing checksum, can be run. When the total value is reached, it is reduced by...

This invention provides a memory card device using an EEPROM (16) as a semiconductor memory. When a data write-in defective area is detected in the storage area of the EEPROM (16), a space area is retrieved from the storage area of the EEPROM (16) as a relieving area and data to be written into the data write-in defective area is written into the relieving area. Then, when the relieving area becom...

A screen suitable for use in temporarily screening an opening into an office cubicle, comprising an integral sheet of material having a series of parallel fold lines dividing the material into a series of normally vertical panels and allowing it to fold in accordion fashion. The material has sufficient stiffness to allow it to form a screen at least 5 feet in height and to be substantially self-su...

Electric elements such as a resistance chip, a capacitor chip, a semiconductor device package, and a connector are mounted on a printed circuit board by using at least two methods selected from the re-flow method using cream solder, the chip-on board method using bonding wires, the outer lead bonding method, and the thermal pressing method using heat-seal. The printed circuit board is provided wit...

The present invention is a bulk storage facility having a reclaim system for providing a continuous controlled feed of difficult to handle cohesive materials characterized by their tendency to pack together to form relatively self-sustaining walls which are substantially resistant to avalanching. The system comprises a reclaimer that passes over the top surface of a mound of material collecting an...

A tape carrier comprises an insulating film and a pattern formed of a metal foil on at least one side surface of said film, said tape carrier being characterized in that an adhesive resin overcoat is applied to the pattern surface portion around a portion to be coated with an IC sealing resin, and a polyimide resin-based overcoat is applied to the remaining pattern surface portion.

A peel seal zipper tape for reclosable plastic bags or packages includes a first and a second mutually interlocking zipper profile disposed on a top surface of a laminated film strip. The top surface is formed by a layer of a sealant material. The laminated film strip also has a bottom surface formed by a layer of a non-peel-seal material. In use, the laminated film strip is f...

An optical coupler/splitter having an optical waveguide on the side of light incidence, two optical waveguides on the branched side, branched from the former optical waveguide and each having straight and curved sections, and a dielectric multi-layer film filter provided in a manner crossing the latter waveguides and common to them. The filter is so formed as to intersect with a straight section o...

A high frequency heating apparatus such as microwave ovens includes an inverter circuit having a switching element and converting a commercial ac power supply to a high frequency power supply by controlling "on" and "off" periods of the switching element, a magnetron driven by the inverter circuit, a counter cumulatively counting an operating period of time and a deenergization period of time of t...

Disclosed is a method and apparatus for partial floor water driving to remove residual heat when the nuclear fuel in a nuclear reactor is exchanged. In the method, a bypass pipe is installed between the inlet and outlet of a residual heat removing pump. A flow regulation valve is installed in the bypass pipe. The bypass flow volume is increased when the residual heat of nuclear reactor is decre...

A heat storage, in particular for automotive vehicles, includes a storage housing which consists of an internal casing of a not round cross-section and an external casing enclosing the former in spaced relationship and a heat insulation, in particular a not supportive high vacuum insulation, enclosed between the internal and external casings. The cross-section of the casing shell of at least the i...

A method which makes usage of a personal secured device (PSD) comprising a smart token reader coupled to a smart token and a secure transaction server (STS) to provide full end to end transactional security over any network. The Smart Token is inserted inside the PSD. The user then has to enter his own personal activation code key (PACK) to unlock the Smart Token. He then chooses his method of pay...
