Title: Inlet port metering system fuel injection pump
Inventor: TAKAHASHI IKUO
IPC: F02M59/36
Filed: 1983-04-04
Abstract: PURPOSE:To reduce a pressure loss between a solenoid valve and an operating chamber and permit to supply fuel proportional to the opening time of a valve by making the opening of the inlet port larger than the opening area of a choked part. CONSTITUTION:When the solenoid valve 22a is opened under a fuel sucking condition in which the inflow part 12 of a rotary distributor 1 is communicated with an inflow path 10, pressurized fuel from a supply pump inflows into the operating chamber 14. Accordingly, a shaft 9 is pushed down and the fuel in an intermediate chamber 20 inflows into a low pressure chamber 17. At this time, a timing inflow path 11 is formed so as to coincide with a timing inflow port 13, therefore, the pressurized fuel inflows into a timing operating chamber 15 when the solenoid valve 22b is opened. When the amount of fuel, inflows into the timing operating chamber 15, increases, plungers 7a, 7b move toward outsides thereof mutually. The timing inflow path 11 is choked in the same condition as the inflow path 10.

Title: Radiographic device
Inventor: ONUKI MITSUO
IPC: A61B6/06
Filed: 1989-03-13
Abstract: PURPOSE:To evade the useless irradiation with radiant rays to the object to be irradiated even when the photographing distance becomes longer by variably controlling the aperture area of a collimator corresponding to the change in the distances between a radiation source and the collimator, and a projected image recording means. CONSTITUTION:The radiation source 2 for irradiating the object to be irradiated 7 with radiant rays and the collimator 3 are integrally constituted so as to contact with and separate from the projected image recording means 16. Corresponding to the distance which is changed by their contact and separation, the aperture area of the collimator 3 is variably controlled. That, means, by variably controlling the aperture area of the collimator 3 corresponding to the change in the distance, the solid angle of radiant rays which is restricted by the aperture area of the collimator 3 is automatically set to the value suitable to the distance. Thus, even when the photographing distance becomes longer, the useless irradiation with radiant rays to the object to be irradiated 7 can be avoided.

Title: Charging device of electrophotograhic copiers
Inventor: TSUTSUMI TAKASHI
IPC: G03G15/02
Filed: 1978-05-18
Abstract: PURPOSE: To prevent the occurrence of ozone and jam by opposedly disposing a charging roller and a grond roller to a dielectric-covered roller.  
     CONSTITUTION: A charging roller 2 and a ground roller 3 are opposedly disposed to a dielectric covered roller 1 and negative voltage is applied to th charging roller 2 by a power source E. The core of the dielectric-covered roller 1 and the ground roller 3 are grounded. Photosensitive paper P is fed between the dielectric-covered roller 1 and the ground roller 3, with its zinc oxide layer coated face being faced toward the dielectric-covered roller 1. This produces potential differences between the charging roller 2 and the core of the dielectric-covered roller 2, causing the dielectric at the contact part of both rollers 2, 1 to polarize. Then the roller suface is charged negative and the charging potnetials of the dielectric are divided in accorddance with Paschen's law and the electrostatic capacity ratios of the dielectric and photosensitive layer, whereby the photosensitive paper P is charged. Hence, charging is accomplished without making use of the corona dischage and the occurrence of ozone is prevented. In addition, the occurrence of jam is obviated because the photosensitive paper P is charged while being fed by the roller pair.

Title: Exchange cassette for transferring film for carrier tape to base plate
Inventor: KURISUTOFU MANUUSHIYU
IPC: B41J32/00
Filed: 1990-03-12
Abstract: PURPOSE: To prevent the generation of slackening by reducing the braking moment acting on a supply reel until a tape stock is perfectly delivered from the supply reel at least in the initial rotation of the extremely slight number of rotations of the supply reel. CONSTITUTION: The braking moment is exerted on a supply reel 8 so as to be reduced to a desired degree corresponding to the delivery distance of a coated carrier tape 11. In this case, the braking moment generated when a tongue piece 20 having spring action is axially pressed to the flat end surface of the reel core of the supply reel 8 is increased only by the friction of the tongue piece. As tape consumption increases, the braking moment is reduced to a desired degree. The rising of the initial braking moment is caused by the running-in of the mechanism of the whole cassette and has no meaning in the delivery stage of the supply reel and is of little importance as compared with the reduction of the important braking moment Mp succeedingly generated up to the delivery completion of a winding stock 12 on and after.

Abstract: PURPOSE: After the condensation reaction between a cyanoacetic ester and formaldehyde is conducted in an aqueous emulsion or suspension, the resultant polymer is depolymerized to produce the titled compound used as an instantaneous adhesive through safe processes in high yield.  
     CONSTITUTION: The reaction of a cyanoacetic ester with formaldehyde is conducted in the presence of a base catalyst such as piperidine in an aqueous emulsion or suspension system. An example of the emulsifier or suspension stabilizer is a surfactance of various kinds or a water-soluble high-molecular substance such as gelatin. The reaction is effected at 50W100°C for several hours. Then, the resultant polymer is depolymerized under a reduced pressure of 1W10mmHg at 150W200°C to give an α- cyanoacrylic ester. Since no solvent is used, there is no danger of inflammation and no problem of environmetal pollution.

Abstract: PURPOSE:To eliminate the need for changing an original disk, a stamper, etc., and to easily cope with a change even when the using conditions of the disk is changed by changing the material quality of a refractive index adjusting film. CONSTITUTION:A refractive index adjusting film 4 having fixed thickness is formed on a surface where a bit 1a of a disk 1 is formed. A metallic reflecting film 5 and a protective film 6 such as aluminum are formed on the rear surface of the film 4. By such a constitution, when the depth (d) of the bit 1a is equal to a light wavelength lambda, and the refractive index of the film 4 are respectively set at (n) and (n'), since the conditions to obtain a maximum level difference for the light receiving quantity of a light receiving device is d=lambda/4(n-n'), by making (d) constant, and by suitably selecting the material of the film 4, the conditions can be satisfied. Consequently, the change of the using conditions such as the change of the light wavelength can be easily coped with by using the material at the desired refractive index without producing the original disk and the stamper again.

Title: Optical element for laser
Inventor: WAKATA HITOSHI
IPC: G02B27/00
Filed: 1988-03-11
Abstract: PURPOSE:To prevent the arrival of laser light at elastic bodies, the deterioration of the elastic bodies and the contamination of the optical system by applying coating films which shield the incident laser light on the elastic bodies to the parts of the optical element body surfaces which come into contact with the elastic bodies. CONSTITUTION:The greater part of scattered light 13 is reflected by the coating films 15 formed by coating metals such as Al and Ti to the parts, except the parts where the laser beam passes, of the surfaces of the optical element 50 which come into contact with the elastic bodies 14 so that the scattered light does not arrive at the elastic bodies 14. 'Viton(R)' and silicone rubber which are inexpensive and soft are utilizable as the elastic bodies. The coating films 15 may not be made of metals and may be multilayered dielectric films. Formation of the nonreflection coating films 16 as used with general optical equipment in place of the coating films 15 is also effective to decrease the quantity of the scattered light. The effect is much higher if both are used in combination. The laser light such as scattered light is thereby prevented from arriving at the elastic bodies such as O-rings. The contamination of the optical element is thereby decreased and the excimer laser which obviates the degradation of laser output is obtd.
