Title: Image recorder
Inventor: YAMANAKA HIROMICHI
IPC: G03G21/00
Filed: 1994-12-29
Abstract: PURPOSE: To provide an inexpensive image recorder such as a laser printer capable of surely feeding a paper from a manual feeding tray. CONSTITUTION: When a manual feeding tray selection switch 11 of a host computer 10 is turned on, the display is executed for operator to confirm the presence or absence of the sheet in the manual feeding tray 2 by a warning means 4, and simultaneously the operation of a feeding means 20 is stopped by a paper feeding inhibition means 21. When the operator confirms the presence of the sheet in the manual feeding tray 2 and the operator turns on a releasing means, the control signal is outputted from the host computer 10, the display of the warning means 4 is released, and the stopping state of the feeding means 20 is released by the paper feeding inhibition means 21.  Thus, even though the expensive sensor for detecting the presence or absence of the sheet in the tray 2 is not provided, the erroneous feeding of the sheet in a paper feeding tray 1 is prevented, and the sheet in the manual feeding tray can be surely fed by the feeding means 20.

Filed: 1990-11-30
Abstract: PURPOSE:To obviate the installation of a heater designed to protect a refrigerating chamber from excess cooling as a new excess cooling prevention measure by turning ON a ventilation fan and a defrosting heater when a compressor for refrigerant circulation is turned OFF during cold open air temperature and turning OFF said defrosting heater when the temperature in the refrigerating chamber reaches a specified temperature. CONSTITUTION:When it in determined that the open air is cold by an open air temperature sensor, a microcomputer outputs a signal to supply power to a defrosting heater 21 and a ventilation fan 16, thereby generating heat from the defrosting heater 21. The heat generated from the defrosting heater 21 is circulated through a refrigerating chamber 26 by means of the ventilation fan 16. When the temperature reaches a specified temperature in the refrigerating chamber 26, the ventilation fan 16 an the defrosting heater 21 are turned OFF by a signal transmitted from a thermistor mounted in the refrigerating chamber 26, which prevents the refrigerating chamber from excess cooling. This construction makes it possible to eliminate the need for installing a new heater designed to protect the refrigerating chamber from excess cooling as an excess cooling prevention practice and hence reduce production cost.

Filed: 1993-12-13
Abstract: PURPOSE:To obtain an acceleration converter being relatively small in size, having a high natural frequency and high strain output sensitivity, being easy to assemble and durable and having long-time stability. CONSTITUTION:An acceleration converter is constructed of a cantilever 3 made up of a follower part 3a, a flexible part 3d and a weight part 3e, a pair of strain generating plates 4 and 5, four strain gages SG1 to SG4 and a casing 1. Due to vibration, an impact or the like applied to the follower part 3a from an object of measurement, the weight part 3e is displaced relatively to the follower part 3a by a force of inertia. Then a tensile strain and a compressive strain are generated in the strain generating plates 4 and 5. Simultaneously, the shapes of the strain generating plates 4 and 5 are so changed as to swell in the same direction as the displacement of the weight part 3e by the force of inertia acting on the strain generating plates 4 and 5 and thereby a bending strain is generated. The strain generated by these tensile and compressive stains and the bending strain added thereto are detected by the the strain gages SG1 to SG4 attached to the strain generating plates 4 and 5.

Abstract: PROBLEM TO BE SOLVED: To control molten iron casting quantity into a mold by pre-obtaining the relation between the width of molten iron surface in a shifting direction of the mold and the capacity, detecting the width of the molten iron with hot block detector and adjusting the pouring quantity or the shifting speed of the mold so that the width of the molten iron surface in the mold becomes the constant. SOLUTION: The hot block detector 2 is arranged at the position pouring the molten iron into the mold. The molten iron is poured into the mold and the boundary surface between the mold and the molten iron surface, is detected with the hot block detector 2 to measure the width of the molten iron surface in the shifting direction of the mold. The shape of the mold is different with the individual molten iron casting machine, but the molten iron quantity can be calculated with the width of the molten iron in the mold. The relation between the width and the capacity is pre-stored into a table in a function generator 50. The width of the molten iron in the mold is converted into the molten iron quantity with the function generator 50 and compared with a target pouring quantity Qs and inputted into a PID controller 52 as a deviation 51.  The PID controller outputs such mold pouring speed 54 that the deviation 51 becomes zero.

Abstract: PROBLEM TO BE SOLVED: To previously prevent the deficiency and excess of etching and to make it possible to form uniform and excellent surface ruggedness free from variations in mechanical characteristics and corrosion characteristics by forming protective layers to two-layered structures varying in etching rates. SOLUTION: The surface of a nonmagnetic substrate 1 is provided with a nonmagnetic metallic ground surface layer 2 and the surface of the layer is provided with a ferromagnetic alloy magnetic layer 3 of a CoNiPt system as a magnetic layer. The first protective layer 4 of a carbon system contg. 30atm.% Si and having 50Å film thickness is formed thereon and further, the second protective layer 5 contg. hydrogen and having 150Å film thickness is formed thereon. After a mask is formed over the entire surface thereof, the layers are subjected to reactive ion etching.  At this time, the etching rates are 20Å per second for the second protective layer 5 and <=1Å per second for the first protective layer 4 and, therefore, the surface mask is completely washed away by executing the reactive ion etching for 10 seconds at which the complete removal of the second protective layer 5 is possible. As a result, the variations in the projection heights of the parts concealed thus far by the mask are suppressed.

Abstract: PROBLEM TO BE SOLVED: To rapidly adjust a size of a laser beam without revising the magnification, etc., of the laser beam by adjusting the beam size made incident on an objective lens between lenses of a beam expandor and adjusting the laser beam size exposing a surface to be exposed. SOLUTION: An adjustment part adjusts the laser beam size by moving a pin hole along the optical axis of the lenses of the beam expandor according to the laser beam size to be emitted to the surface to be exposed.

Title: Separator
Inventor: NIEKERK ERASMUS VAN
IPC: F24C15/20
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To effectively separate pollutant, etc., from gases or vapor and take the refined gases or vapor out of a bed by passing the gaseous flow or vapor flow polluted with the pollutant, etc., to the lower part of the bed of spiral separating media. SOLUTION: The air carrying fats and oils enters the apex of a separating zone 50 from the conduit 16 of the separator 22. The velocity of the air entering a basket 54 and passing the bed 62 falls as is evident when the enlarged cross section of the basket 54 is contrasted with that of the conduit 16. The air flowing downward meets the spiral separating media 70. The separating media 70 afford the contact surfaces against which the entrained fats and oil collide and by which the fats and oils can be captured. The sufficient or excess oils and fats are deposited on the separating media 70 and are dropped by gravity from the separating media 70 onto a tray 52. The air substantially free from the oils and fats enters the separating zone 50 under the basket 54 at the lower velocity.  The air, then, enters the space between the bottom end of a baffle plate 64 and the conduit 24 at the higher velocity and emerges outside through the conduit 24 at the higher velocity.
