Title: Controller for pulse width modulation inverter
Inventor: MUTOO NOBUYOSHI
IPC: H02M7/48
Filed: 1978-12-11
Abstract: PURPOSE: To perform quick changeover even if a changeover instruction is applied at arbitrary time, by converting the output signals of an oscillator and a frequency divider into carriers synchronized with each other but different in frequency from each other and by synchronizing the changeover instruction with the output signal of the frequency divider.  
     CONSTITUTION: A frequency instruction Vf is applied to an oscillator 2 through a buffer circuit 1 to generate a rectangular wave (a). A pulse (b) is produced by a reset pulse generation circuit 3 and applied to an inverter 4 to generate a rectangular pulse train. A saw-toothed wave (e) is produced from the pulse train. Another rectangular pulse train (c) is produced by a frequency divider 5 which divides the output frequency of the oscillator 2. The latter rectangular pulse train is applied to a reset pulse generator 6 to produce a pulse (d). This pulse is applied to the inverter 4 to generate another rectangular pulse train. Another saw-toothed wave (f) is produced from the pulse train. The saw-toothed waves (e), (f), which are carriers generated by the oscillator and the frequency divider which divides the frequency of the output of the oscillator, are always synchronized with each other. This results in quickening changeover.

Abstract: PURPOSE:To equalize phase variation quantity so as to make its compensation unnecessary by making a first and a second light waves branched by a polarization beam splitter are made incident from both ends of a plane of polarization holding optical fiber so as to pass through to other end respectively. CONSTITUTION:When the light wave is emitted from a laser light source 16 at a linear polarization bearing 45 deg., the first light wave (full line) and the second light wave (dot line) reach a light receiving element 24. Namely, the light wave emitted from the laser light source 16 in a state to have polarization axes of a vertical direction and a horizontal direction is transmitted and reflected through/by the polarization beam splitter 14, and is branched into the first light wave with the polarization axis in the vertical direction and the second light wave with the polarization axis in the horizontal direction. Then, they are rotated in left by 45 deg. at their polarization axes by Faraday rotors 12, 18, and are made incident to the both end surfaces of the plane of polarization holding optical fiber 10. Thus, the optical paths of the first light wave and the second light wave become completely the same length, and a phase variation compensator is made unnecessary.

Abstract: PURPOSE:To unify distribution of the velocity of the wide while remarkably improving radiation efficiency of a cooling fin by uniformly arranging cooling fins ranging over nearly the whole region of the circulation path of the cooling air. CONSTITUTION:Serrated small pieces 5-1-5-3 shifted from the serration-starting positions 5a-1-5a-3 form groups to be bent sideways downwards from the serration-starting positions 5a-1-5a-3 and these are turned up sideways at the bent parts 5c-1-5c-3 while shifting their positions respectively. As a result, the neighboring serrated small pieces 5-1-5-3 turning to the same direction hold a positional relation having a gap C1 between the serrated small pieces 5-1-5-2 while a gap C2 between the serrated small pieces 5-2-5-3 seen from the direction of the cooling air flow. The other serrated small pieces are also similarly formed. In this way, the cooling fins are uniformly arranged ranging over nearly the whole region of the cooling air circulation path thus unifying distribution of the velocity of the wind and remarkably improving radiation efficiency.

Filed: 1988-06-20
Abstract: PURPOSE:To prevent staying of a developer by forming the outer peripheral margin of the no-bucket fitting section of the bucket supporting body of the roller thinner in thickness than the bucket fitting section of the supporting body. CONSTITUTION:At the outer peripheral margin of a flange 53, the plate thickness T1 of the no-bucket 54 fitting section is made thinner than that T2 of the bucket 54 fitting section and a slope section 53a is formed toward the inside. A scraped-off developer moves along the slope section 53a from the outer peripheral margin and is fetched into a bucket roller 55. Therefore, the scraping-off operation of a scraping-off section 55 or scraping-off member 60 is not interfered at the extent corresponding to the thickness of the outer peripheral margin of the no-bucket fitting section of the flange 53 even when the bucket fitting section is thick in thickness and the developer is efficiently scraped off.

Title: Device mounted to aircraft for airdropping body
Inventor: DEEGEN MATSUKUSU
IPC: B64D1/04
Filed: 1981-09-29
Abstract: To drop objects from a container or receptacle mounted at an aircraft there is beneficially employed a pressure head. For this purpose the object mounted internally of the container upon guide rails is impinged at its front end by the flight-pressure head of the aircraft, so that it is ejected from the tail end of the container. For rapidly realizing the necessary safety distance between the aircraft and the dropped object at the tail end of the container there is deflected a flow onto the departing object, so that a pressure pulse is applied to the object and it is accelerated. The invention is particularly suitable for accurately laying a multiplicity of objects at surface-like or areal targets i.e. upon a given terrain. Its use is contemplated for both civilian applications, such as dropping life saving and supporting equipment and so forth, and military applications, such as for dropping bombs, especially fragmentation bombs, mines and other ordinance. The apparatus is extremely simple and functionally reliable. The only movable auxiliary means needed is a controllable bolt or equivalent structure within a blocking device for the release of the object.
