Title: Radio receiver
Inventor: NIWAYAMA MASANORI
IPC: H04B1/26
Filed: 1981-06-22
Abstract: PURPOSE:To reduce the tracking errors of a radio receiver by differentiating the changing ratio of capacity of a varactor diode of a high-frequency (HF) amplification stage from that of a varactor diode of a local oscillator. CONSTITUTION:A signal from an antenna 1 is passed through an HF amplifier 2 of an HR amplification stage 100, selected by a tuning circuit 3 and inputted to a mixer together with a local generating signal generated from a local oscillator 10 to perform frequency conversion. Varactor diodes of the local oscillator 10 are connected in parallel to a varactor diode 6 of the tuning circuit 3. The varactor diodes 6, 11 have the similar characteristics, but the varactor diode 21 is set up so that the change of chapacity is reduced. Consequently the whole changing ratio of capacity on the local oscillator side is smaller than that of the HF amplification side, extremely reducing tracking errors.

Title: Optical waveguide and its manufacture
Inventor: WADA YOSHIKI
IPC: G02B6/13
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To easily constitute an optical waveguide reduced in propagation loss. SOLUTION: At a bend part 102a which is a part where the direction of the optical signals of a waveguide 102 is changed, an exposed side face 102b exposed without a clad layer to a core 112 on an outer side to which the optical signals are bent is provided. The side face becomes a reflection surface and the propagation direction of the optical signals propagated through the core is changed to the bending direction of the core. Thus, since the need of forming the reflection surface composed of the thin film of a metal or the like other than a clad around the core is eliminated, the propagation loss is reduced and the constitution of this optical waveguide is easily formed.

Title: Distance-measuring apparatus and safe running system
Inventor: TOUEI HIDEKI
IPC: B60W30/00
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To provide a distance-measuring apparatus which does not measure a distance erroneously even when a plurality of objects to be detected exist in a visual field range and to detect respective distances of the plurality of objects to be detected. SOLUTION: A right image which is outputted from a photodetector 23a on one side is shifted one pixel by one pixel by an image shift processing part 24. An agreement judgment part 25 compares the shifted right image with a left image which is outputted from a photodetector 23b on the other side, and it cuts out a region in which an agreement degree is high. A correlation computing part 26 finds the deviation amount between regions in which the agreement degree of the right and left images is found out to be high, and it finds the distance of an object to be detected on the basis of the deviation amount.

Title: Centrifugal thin film dryer
Inventor: SATOU MASAAKI
IPC: G21F9/08
Filed: 1984-05-17
Abstract: PURPOSE:To reduce the abrasion of a rotary blade and the inner surface of an external cylinder, by making it possible to adjust the rotary blade in a centrifugal thin film dryer so as to bring the same to the contact or non-contact state with the inner surface of the cylinder corresponding to the number of rotations. CONSTITUTION:A solution to be treated is introduced into a cylinder 2 from a supply port 6 and the powder in the solution is adhered to the inner surface of the cylinder 2 in a thin film form by centrifugal force due to the rapid rotation of a rotary shaft 4. The thin film is dried by the heat of an outside steam jacket 1 and further fallen in a lower hopper 7 while scraped off by the rotation of rotary blades 3 when said thin film is formed, the leading end of each rotary blade 3 is separated from the inner surface of the cylinder by the centrifugal force due to the rotation of the blades 3 and the resultant moment of the springs 10 provided to one ends of the blades 3 and abrasion caused by the contact of both of them is prevented. When the thin film is scraped off from the inner surface of the cylinder, the number of rotations are adjusted to bring the leading ends of the blades 3 into contact with the inner surface of the cylinder to perfectly scrape off the powder thin film. Because the leading ends of the blades are brought into contact with the inner surface of the cylinder only when the membrane is scraped off, abrasion by the friction between both of them is reduced.

Title: Manufacture of negative electrode for secondary battery
Inventor: NAKAMURA YASUO
IPC: H01M4/1395
Filed: 1987-04-22
Abstract: PURPOSE:To form an electrode having high strength and substantially large specific surface area to obtain a battery having high current density by bonding aluminium-low melting point metal alloy with thermoplastic polymer. CONSTITUTION:Aluminium-low melting point metal alloy, carbon powder, and carbon fiber are mixed with polymer powder. The mixture is bonded on an electrode substrate such as expanded metal by thermal press molding to form an electrode. In this process, the temperature lower than the softenining point of the polymer is preferable, and the pressure similar to the compression molding pressure of the polymer is preferable. Since the aluminium-low melting point alloy easily forms an oxide film, the treatment in an inert gas atmosphere or in a vacuum is required. A negative electrode which is lightweight and has large specific surface area and good molding and working capability can be obtained as the negative electrode for a secondary battery in which lithium ions are taken in and out.
