Title: Optical multiplexer and demultiplexer
Inventor: TOJO MASAAKI
IPC: G02B6/293
Filed: 1985-05-08
Abstract: PURPOSE:To eliminate the influence of the chromatic aberration of a rod lens and to produce easily an optical multiplexer and demultiplexer which decreases the crosstalks between wavelengths by slanting the top end of an optical fiber array, bringing an interference film filter into tight contact with part of the sloped top end face and bringing the same via a transparent body piece into contact with the rod lens. CONSTITUTION:The light of the wavelength lambda1 emitted from an optical fiber 9a is converted by the rod lens 13 to parallel rays which are reflected by the interference film filter 14 for reflecting the light of the wavelength lambda1. The reflected rays are again condensed by the lens 13 and are made incident on an optical fiber 9b. The filter 14 allows the transmission of the light of the wavelength lambda2 but about 10% thereof is reflected by the filter. The interference film filter 12 which allows the transmission of the light of the wavelength lambda1 and reflects the light of the wavelength lambda2 is adhered to the end face of the fiber 9b to prevent the incidence of the reflected light of the wavelength lambda2 on the fiber 9b. The light of the wavelength lambda2 emitted from the fiber 9b is again converted by the lens 13 to the parallel rays which transmit the fiber 14, are reflected by a reflecting mirror 15, are condensed again by the lens 13 and are made incident an optical fiber 9c.

Title: Cornering limits detector
Inventor: KATADA KUNIO
IPC: B62D15/00
Filed: 1983-06-01
Abstract: PURPOSE:To aim at a significant improvement in the safety of a car, by using a characteristic point existing between salfaligning torque and tire axial load, and thereby detecting a cornering limitation in advance under extensive conditions even if the running condition is varied. CONSTITUTION:In wheels 2a-d, sensors 3a-d detecting the turning force and torque produced in wheels are being built in these corresponding wheels 2a-d. As for speed sensors 3a-d, a six-component measuring device or the like is used. Each output of these sensors 3a-d is set down as an input signal for a data processing circuit 4 and calculates a cornering limitation, inputting it into a warning device 5 and informing a driver of the cornering limitation. Owing to characteristics in a time differential signal in tire load and selfaligning torque in time of running, the running tire axial load grows larger than the stop axial load and, what is more, a time differential value becomes positive.

Title: Projection type cathode-ray tube
Inventor: YOSHIDA TETSUYA
IPC: H01J29/00
Filed: 1983-05-31
Abstract: PURPOSE:To improve radiation effect and luminescent efficiency by a method in which a light-transmitting plate is airtightly connected in front of the bulb face part, inside of which a phosphor film is formed, for being filled with a cooling liquid while leaving an air gap together with reducing pressure inside the air gap. CONSTITUTION:An enclosed space surrounded by a bulb 1 and a plate 7 is filled with a cooling liquid while leaving an air gap 11 with together exhausting the inside of the air gap 11. For instance, in a cathode-ray tube having a picture screen of 5 in. in size, the enclosed space of 25cc is filled with 24cc of a water solution containing 30% of ethylene glycol while forming the air gap 11 of about 1cc. And the inside of said air gap 11 is reduced down to 0.5 of atmospheric value. Thereby, an increased volume of about 0.5cc of the cooling liquid 9 is absorbed by compressing the air gap 11, whereby pressure inside the air gap 11 is so much raised as the compressed portion while further raising internal pressure due to the added vapor pressure of the cooling liquid. However, a pressure rise is also checked due to prior reduction in pressure while causing no damages to sealing thus preventing a panel 7 and the bulb 1 from breaking.

Title: Ventilating device for kitchen facility
Inventor: PARMENTIER MICHEL
IPC: B04C9/00
Filed: 1989-04-19
Abstract: PURPOSE: To enhance an ability to decompose odor by providing a cyclone separator for cooling vapor and various aerosols which are generated at the time of cooking to reduce them into water and oil and the like. CONSTITUTION: A hood 3 is communicated with a cyclone separator 5 by way of an air supply pipe. This cyclone separator 5 functions as a condenser (vapor compression and cooling apparatus). A body 7 of the cooling apparatus is disposed outside of the cyclone separator 5 and a cooling plate 6 is disposed at the upper portion of the inside of the cyclone separator 5. Vapor generated upon use of a cooking facility 2 is transferred from the hood 3 to the cyclone separator 5 by an operation of a suction turbine 10 and here the vapor is rapidly cooled. As a result, the vapor is separated into gas, water and aerosols in a liquid form which is reduced by cooling.

Title: Solid-state image sensing element
Inventor: OKI HIROAKI
IPC: H04N5/372
Filed: 1996-03-27
Abstract: PROBLEM TO BE SOLVED: To avoid mixing stored charges between vertically adjacent pixels to improve the sensitivity by implanting a p-type impurity between photoelectric converters successive in vertical direction to form vertical pixel isolated regions. SOLUTION: A CCD solid-state image sensing element 20 has p-type regions 21 to form a barrier of stored charges in lower parts of vertical pixel isolated regions AV by implanting ions of a p-type impurity at a higher energy. The p-type regions 21 are formed by patterning within a range narrow enough to avoid extending to charge stored regions 22 of photo sensors 2 in vertical direction and avoid extending to adjacent transfer registers 3 in horizontal direction. In the depth direction, according to the depth of the overflow barrier 11, the forming position is selected so as to avoid locally depleting the regions AV. Thus, the mixing of stored charges between adjacent pixels can be avoided to improve the sensitivity.

Title: Manufacture of lead alloy sheet
Inventor: MORINARI RIYOUSUKE
IPC: C21D1/34
Filed: 1979-07-31
Abstract: PURPOSE: To manufacture a dependable Pb alloy sheet by applying laser beams to both sides of a sheet manufactured by a DM method (Direct Method at Casting Lead Sheet) to melt and solidify surface layers in a short time, thereby reducing the grain size.  
     CONSTITUTION: Pb or Pb alloy sheet 1 manufactured by the DM method is fed between shaping rolls 7 to carry out levelling for the unevenness due to casting, and transferred to the next surface treatment station 8, where laser beams 10 from beam sources 9 are suitably reduced in beam size and applied to the surfaces of sheet 1. While moving the sheet 1 in the longitudinal direction, the beams are scanned in the lateral direction of sheet 1 at a relatively high speed to melt sheet 1 up to an appropriate depth from the surfaces. Since the beams are applied only to restricted regions for a short time, sheet 1 is melted and solidified in a short time. The cooling rate is high, so that solidified structure has a remarkably raduced grain size.

Abstract: PURPOSE:To inform an appropriate cleaning time to a user by counting the quantity of dust which passes through between a light emitting element and a light receiving element provided opposingly on the outer shell of a vacuum cleaner, and informing it when it becomes a prescribed count. CONSTITUTION:On the outer shell surface 3 of a vacuum cleaner, a light emitting element 4 and a light receiving element 5 are placed opposingly so that dust drops down between them. When dust floating in a room drops down between the light emitting element 4 and the light receiving element 5, the quantity of light which reaches the light receiving element 5 decreases for an instant, and the light receiving element 5 detects this decrease of the light quantity and outputs a pulse. This pulse is counted by a counter 6, and when it is counted until a set value, the counter 6 outputs an inversion output to a driving circuit 7, turns on a notice lamp 8, and informs a cleaning time to a user. When the user notices the notice lamp 8 and inserts a cord plug to a commercial power source, the output of a photocoupler 11 is inverted and the count value of the counter 6 is released and initialized.
