Abstract: PURPOSE:To raise the extinction ratio and to eliminate a need of adjustment of angles of inclination of polarizing films by arranging two polarizing films at 45 deg. to the incident light in the same direction or opposite directions in a glass body. CONSTITUTION:Two polarizing films 2a and 2b inclined at 45 deg. to the incident light are arranged in parallel in a square prism-shaped glass body 1, thereby constituting a polarizing beam splitter. Two polarizing films 2a and 2b may be arranged at 45 deg. to the incident light in opposite directions. With respect to formation of polarizing films 2a and 2b in the glass body 1, a high-refractive index film and a low-refractive index film consisting of a non-absorption transparent material are alternately laminated on two slopes of parts, namely, two triangular prisms and one parallelogrammic prism of the glass body 1, which is divided along slopes inclined at 45 deg. where polarizing films should be formed, by vapor deposition, and thereafter, respective parts of the glass body are adhered into a square prism.

Title: Fail-safe device in auxiliary steering gear for vehicle
Inventor: EGUCHI TAKAAKI
IPC: B62D7/14
Filed: 1989-05-02
Abstract: PURPOSE:To control a vehicle so as not to produce a sudden change of its offensive behavior by installing a trouble detecting means and an auxiliary steering angle change speed control means controlling speed of an auxiliary steering angle change with abnormal occurrence at time of trouble, respectively. CONSTITUTION:At time of front-wheel steering, at least either side of both front and rear wheel is auxiliarily steered according to a car speed detected by a car speed detecting means, thereby improving the extent of vehicle's maneuverability. When the car speed detecting means suddenly changes the detected car speed by something wrong due to disconnection and chattering or the like, a trouble detecting means detects it and functions as an auxiliary steering angle change speed control means. This means controls the speed of auxiliary steering angle change accompanied to a sudden change in the detected car speed at time of trouble without following the sudden change of the detected car speed. Accordingly, even if the detected car speed is suddenly changed due to trouble in the car speed detecting means, the auxiliary steering angle is not changed at all with corresponding high speed, so that this sudden change of vehicle behavior can be prevented from making any feeling to a rider.

Title: Safety device for combustion
Inventor: TANAKA EIICHI
IPC: F23N5/10
Filed: 1978-09-12
Abstract: PURPOSE:To accomplish safe operation accurately even at the oxygen starvation by means of two thermocouples arranged in a specified manner. CONSTITUTION:The first thermocouple 16 is arranged above the primary flame port 11 of a pilot burner 7 and the second thermocouple 17 is at a fixed distance above the main gas burner 3. With such an arrangement if the pollution of the air causes a drop in the oxygen concentration after the formation of the primary flame A at the primary flame port 11, the secondary flame B at the secondary flame port 8 and a flame C at the main gas burner 3, sensitively reacting to the drop, the primary flame A goes out while the flame C is lengthened due to the shortage of the oxygen. Consequently, as the primary flame A grows unstable, the thermal electromotive force of the first thermocouple 16 begins to reduce while the second thermocouple 17 slightly increases the thermal electromotive force as the flame C grows long. Thus, the difference in the electromotive force between the two thermocouples 16, 17 diminishes so much that a gas electromagnetic safety valve 5 is closed. Thereafter, the supply of gas is halted to ensure safety.

Title: Image pickup type border detection device
Inventor: HAYASHI MASAHIKO
IPC: G05D1/02
Filed: 1987-05-09
Abstract: PURPOSE:To detect a border by using image information on a wide range in the lengthwise direction of the border by setting the number of picture elements to be processed which are arranged in the lengthwise direction of the border larger than the number of picture elements to be processed which are arranged in the direction crossing the border at right angles. CONSTITUTION:An unmoved place B is seen darker than a mowed place C, so when the border L1 is detected, the image range of an object of processing is limited to a laterally long area and the number of picture elements to be processed which are arranged in the lengthwise direction of the border L1 is set larger than the number of picture elements to be processed which are arranged in the direction crossing the border L1 at right angles. The integral value of nine picture elements, i.e. a picture element (e) to be processed and its eight peripheral picture elements (a-d and f-i) is operated as to brightness variation in the X-axial direction on an image. Then such picture elements that the absolute value of the integral value is larger than a set threshold value, namely, that the brightness variation is maximum are extracted to find the straight line corresponding to the border L1 between the unmowed place B and mowed place C.

Title: Ignition device for auxiliary chamber type large gas engine
Inventor: NAKAZONO TORU
IPC: F02P13/00
Filed: 1987-05-08
Abstract: PURPOSE:To enable normal execution of compensation for a failure in ignition even during a failure in ignition of an auxiliary chamber in any case as an increase in generation of NOx is prevented, by a method wherein an ignition plug for a main chamber normally performs an ignition motion. CONSTITUTION:An ignition plug 10 for an auxiliary chamber and an ignition plug 11 for a main chamber, which normally perform an ignition motion during running of an engine, are situated in an auxiliary chamber 2 and a main chamber 3, respectively. In which case, the ignition timing of the ignition plug 11 for the main chamber is set to a timing delayed than that of the ignition plug 10 for the auxiliary chamber, and the ignition plug 11 for the main chamber is ignited at a timing approximately at which a propagation flame ignited by the ignition plug 10 for the auxiliary chamber is extended to the ignition plug 11 for the main chamber. This constitution enables execution of reliable ignition by means of the ignition plug 11 for the main chamber even when a failure in ignition of the ignition plug 10 for the auxiliary chamber occurs during rapid cutoff of a load or the starting of an engine. Besides, since the ignition timing of the ignition plug 11 for the main chamber is delayed, an overincrease in temperature is prevented from occurring, and an increase in production of NOx is prevented from occurring.

Title: Production of polarizing element
Inventor: SHIMIZU SHIYOUTAROU
IPC: G02B5/30
Filed: 1979-09-04
Abstract: PURPOSE: To make possible the diversification of display contents by obtaining a polarizing element which consists in arraying micro-polarizing regions of different rates of polarization and polarization directions in a mosaic shape on one sheet of substrate.  
     CONSTITUTION: Polarized light is irradiated to a thin film comprising a material having light absorption anisotropy so that polarization power is produced by the selective decoloring reaction with selective light absorption. For example, when Argon laser polarized light of 514nm wavelength is condensed to about 10KW/cm 2  and irradiated to a thin film of, for example, dichromatic dye Congo Red (maximum absorption wavelength 520nm and light absorption is anisotropic), the irradiated parts are decolorized instantaneously and a polarizing element of 70% rate of polarization could be obtained as an example. If the laser is scanned in a pattern shape while its polarization direction is changed, a mosaic-shaped polarizing element of locally differing polarization directions could be obtained. In addition, if the laser is scanned while its output is changed, a polarizing element of locally differing rates of polarization could be obtained.
