Title: Fuel cell equipped with protector
Inventor: SONE ISAMU
IPC: H01M8/04
Filed: 1987-01-09
Abstract: PURPOSE:To protect a cell from the abnormal pressure difference by systematizing the automatic stop of fuel and oxidant and the supply of inert gas in a predetermined direction from a pressure vessel with no necessity of using a backup electric source or a computer, when electric power or control signal breaks down. CONSTITUTION:In power failure, for example, solenoid valves 8, 9 are mechanically full closed to stop the feed of fuel and oxidant. Also, solenoid valves 12, 14 are mechanically full closed to let inert gas flow through check valves 13, 15 keeping the pressure balance between inert gas and an anode 1 and a cathode 2 at a predetermined pressure difference. These check valves do not function so far as the pressure at upstream side is not higher than the pressure at downstream side by the pressure loss. By appropriately choosing check valves 13, 15, the holding pressure difference of the anode and cathode against inert gas can be determined. By the arrangement, stable stop of the power generation and retention of the fuel cell becomes possible preventing from its abnormal pressure difference.

Title: Steering position detector for self-travelling vehicle and reference point detector for above device
Inventor: KAMIMURA KENJI
IPC: G05D1/02
Filed: 1989-01-07
Abstract: PURPOSE:To prevent a light beam except the beam coming from a scheduled light reflecting means from erroneously detecting as a reflecting light beam from the light reflecting means by shifting the position of a self-travelling vehicle calculated based on a detection signal from an estimation position when the light beam except the beam from the scheduled light reflecting means is detected. CONSTITUTION:Whether the light beam detected in a light receiver 3 is the reflecting light beam from a reflector 6 arranged in a reference point or not is judged. When they are judged to be the normal reflecting light beams from the scheduled reflector 6, the position and a travelling direction for steering and controlling the self-travelling vehicle is calculated based on a light-receiving signal. A decision whether the light beams are the normal reflecting light beams or not is executed by deciding whether the position of the self-travelling vehicle, calculated whenever the light beam is received is in the scheduled position or not. Thus, the miss of the reference point and noise from excepting the reference point can easily be recognized.

Title: Throttle valve control device
Inventor: KATO HIDEKI
IPC: F02D9/10
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To provide a throttle valve control device capable of manufacture easily and at low cost. SOLUTION: Each of magnetic poles 46 and 47 is formed with a group of magnets each of which comprises four flat plate-shaped permanent magnets 46a and 47a, and each of permanent magnets 46a and 47a is fixed adhesively to the outer periphery of a rotor core 42. Also the permanent magnets 46a and 47a are rare-earth magnets, and each of them is magnetized in one thickness direction, and arranged in arc shape around the periphery of the rotor core 42. Therefore the magnetic poles 46 and 47 are formed so that they are radially magnetized substantially from the center of a rotor 48. Because it is easy to magnetize the flat plate-shaped magnetic body in one direction, the magnetic poles 46 and 47 can be formed easily and at a low production cost.  Because a stator core 45 is formed in slotless structure which is endless all around the rotor 48, the eccentricity of the distribution of magnetic flux in the stator core 45 is reduced and al-so a detent torque acting on the rotor 48 is reduced.

Title: Chip-type electronic component
Inventor: TONEGAWA KEN
IPC: H05K3/46
Filed: 1994-01-14
Abstract: PURPOSE:To obtain a chip-type electronic component in which an inductance component on a transmission line is removed by a method wherein a gap is formed between a circuit element and an external electrode which have been built in a multilayer board and the circuit element and the external electrode are coupled electro-magnetically via the gap. CONSTITUTION:Gaps 13, 13 are formed between an input electrode 11a and an output electrode 12a for a band-pass filter 2 and external electrodes 7, 8. Since they are coupled electromagnetically by a capacitance component due to the gaps 13, 14, no connecting electrode is required. In addition, when the resonance frequency of a series resonance circuit by the capacitance component due to the gaps and by an inductance component due to an electrode and an external electrode for a circuit element is made to coincide with a transmission frequency, the inductance component due to the electrode and the external electrode for the circuit element can be cancelled. As a result, it is possible to prevent the degradation of an electric characteristic such as an increase in a transmission loss, an irregularity in the electric characteristic, the aggravation of an attenuation characteristic, an increase in a spurious component and the like.

Title: Measuring instrument for quantity of curvature of strip steel
Inventor: EBATA SADAO
IPC: G01B11/24
Filed: 1989-01-11
Abstract: PURPOSE:To accurately measure the quantity of breadthwise curvature of the steel sheet by photodetecting light which is projected and reflected by the surface of the steel sheet to return, converting the light into an electric video signal and finding at least the lateral size of the image. CONSTITUTION:The light emitted by a projection light source 3a is reflected by the surface of the steel sheet 1 as a plane mirror to reach a photodetector. A virtual image 8 of the projection light source 3a is projected on the image pickup surface 4b of the photodetector 4 by a lens 4a through the operation of the projection light source 3a. When the steel sheet 1 curves in the width direction convexly, the surface 1a provides convex mirror reflection, so the lateral size of the virtual image 8 is smaller than the lateral size of the projection light source 3a, so that an image of small lateral size is projected on the image pickup surface 4b. The longitudinal size of the image is equal in any case since the steel sheet 1 is tensed straight. It is therefore found that the steel sheet 1 is flat when the ratio of the longitudinal size of the image to the lateral size is 1 and curves convexly (concavely) when smaller (larger) than 1; and the extent of the curvature is know from the rate value.
