Title: Photoelectric transducer
Inventor: TAKAHASHI KAZUHISA
IPC: H01L31/02
Filed: 1977-09-30
Abstract: PURPOSE: To increase the conversion efficiency with decreased crosstalk, by forming the photoelectric transducer on the electric insulator substrate with the substrate used as the cap for enclosure of the transducer and then reducing the distance between the fiber end surface and the surface of the photoelectric transducer down to the substrate thickness.  
     CONSTITUTION: P - -layer 71 of Si and p-active layer 2 are formed on sapphire substrate 70, and n - -diffusion layer 1 is provided to form Ti-gold electrode 3 selectively. The mesa-etching is given via mask 3, and electrode 4 is formed selectively after isolation of the Si layer. When the chip of the photo detector is mounted to package 30 through the above structure, substrate 1 can be used directly as the cover. And the distance between the fiber end surface and the light receiving surface of the transducer can be reduced down to the substrate thickness, thus increasing the photoelectric conversion efficiency as well as decreasing the crosstalk. At the same time, the Si lamination layer is sufficiently thin, and the mesa-etching is possible from the Si layer side. Thus, an easy mesa-etching can be given with the back electrode used directly as the mask even though the active layer may be thick

Title: Thermoplastic elastomer composition
Inventor: INOUE TOSHIO
IPC: C08K5/3437
Filed: 1988-05-17
Abstract: PURPOSE:To obtain a composition excellent in flexibility, heat resistance, weathering resistance, oil resistance, moldability and a freedom of coloration by dynamically heat-treating a mixture of a thermoplastic resin with a C=C bond- containing rubbery substance with a specified compound. CONSTITUTION:This thermoplastic elastomer composition comprises a resin composition obtained by dynamically heat-treating a mixture comprising 60-10wt.% C-C unsaturated bond-free thermoplastic resin and 40-90wt.% C-C unsaturated bond-containing rubbery substance in the presence of a dihydroaromatic compound or its derivative and/or a crosslinking agent. From the viewpoints of the compatibility with the rubbery substance and the properties of the obtained composition, it is desirable to use a polyolefin resin or its mixture as the thermoplastic resin. As the rubbery substance, 1,2-polybutadiene rubber, SBS, SIS or EPDM is desirable, because they are available in the form of pellets and can be easily weighed and handled in mixing, and because they have a high freedom in selecting the type of an apparatus for producing the composition.

Title: Infusion preparation
Inventor: KAWAKAMI KEIICHI
IPC: A61K31/70
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To obtain an infusion preparation having pH near the physiological level and needing no coloring preventing agent by accommodating a plastic infusion container containing a reducing sugar-contained medical fluid sterilized with carbon dioxide dissolved in a fluid with carbon dioxide absorbent in an oxygen impermeable facing container. SOLUTION: Carbon dioxide is dissolved in a medical fluid to lower the pH, and a plastic infusion container containing a reducing sugar-contained medical fluid is sterilized. The fluid container is accommodated with a carbon dioxide absorbent or with a free-oxygen absorber in the case of fatty emulsion reducing sugar mixed infusion in a wrapping container substantially impermeable to oxygen to surely prevent the generation of 5-hydroxymethyl-2-furfural(5-HMF) and the generation of free fatty acid. Thus, pH can be returned to pH before carbon dioxide dissolution in a short time, and the pH of a fluid can be set to the physiological pH range. Simultaneously, the generation of HMF can be prevented and the need of a coloring preventing agent can be eliminated.

Title: Charge/discharge power supply apparatus
Inventor: SHINOZUKA MASAHIKO
IPC: H02J7/10
Filed: 1993-05-20
Abstract: PURPOSE:To provide a charge/discharge power supply apparatus which is small in size but can cope with a wide variety of battery characteristics. CONSTITUTION:As a switching device TSW is provided on the primary side of a transformer T1 for PWM control, the secondary output voltage V1 of the transformer can be varied linearly. Therefore, a constant power type power supply can be realized by monitoring the output voltage V1, so that a dynamic range as a charge/discharge power supply can be expanded even if the size is small. Further, as a minimum necessary voltage can be superposed upon a battery voltage by reducing the ON-period of the switching device TSW at the time of discharge, an additional transformer which is necessary in a conventional constitution can be eliminated and, moreover, unnecessary power consumption in a constant current controller (TR, RX, AMP and VREF) can be eliminated.

The nut is so fixed not to rotate in the rotational direction of the threaded rod 5, and the rotation of the threaded rod 5 moves the nut to shift in the axial direction of the threaded rod 5. The other end of the sine bar 3 fitted to the rotary shaft 2 so contacts a side 8 not to release it. Movement of the knife-edge 4 pushes and moves the sine bar 3, resulting in rotation of the diffraction grating 1 for change in the angle.

The pulse position is detected with the circuit 6 and said position is used as a time reference for distance measurement. On the other hand, a pulse shaping circuit 8 generates a prescribed pulse waveform and transmits the same to a signal transmitter 7 in synchronization with the tigger from a generator 9. The transmission signal is supplied to the antenna 1, and is coupled to a signal receiving system, from which the transmission time reference is derived. The distance is obtained by measuring the time until the time of the return waves is detected. Here, the signal Stau of the delay time tau and the signal SA subjected to attenuation A are compared 13 in the circuit 6, and the signal T rising at the point of intersection thereof is obtained. Said T is used as a time reference.

Abstract: PURPOSE: To realize a low-NOX combustion device applicable on a small-size combustion engine. CONSTITUTION: In a two-stage combustion device, in which combustion air or fuel is supplied by dividing it into primary combustion and secondary combustion to effect combustion, cooling pipes 15, 16 are arranged in respective primary combustion chamber 8 and a secondary combustion chamber 12 while combustion gas is cooled in two steps of the primary combustion chamber 8 and the secondary combustion chamber 12.
