Title: Temperature control device for liquid cooler
Inventor: FUKUNAGA OSAMU
IPC: F25B1/00
Filed: 1988-06-21
Abstract: PURPOSE:To improve temperature control accuracy during the starting of equipment by installing to a refrigerating device a compressor whose operation frequency is controlled variable by an inverter, and setting the operation frequency of said compressor during the starting of said equipment so that it may meet the environmental conditions. CONSTITUTION:During starting an output frequency setting means 31 is adapted to set the output frequency of an inverter 15 so that it may be increased in proportion to a drop in inlet oil temperature. When a compressor 8 is operated for a specified time based on the preset frequency, a temperature difference computing means 32 computed an outlet and inlet temperature difference of coolant. A frequency change means 34 is adapted to change the output frequency of the inverter 15 so that it may be increased and decreased from the value of starting frequency, according to the temperature difference. Even when the temperature of a main shaft is deviated from a control target value, the output frequency of the inverter 15 can be changed as well.

Title: Document printing apparatus
Inventor: MATSUHASHI KENICHI
IPC: B41J19/18
Filed: 1992-06-12
Abstract: PURPOSE:To prevent misregistration in printing in a printing apparatus capable of bidirectional printing by detecting displacement errors of a print head during printing in forward and reverse directions to variably set print starting positions in either of forward and reverse directions. CONSTITUTION:Offsets p and q in forward and reverse directions are initially set in a printing apparatus. A central processing unit sets as fixed values a distance 31 from a print starting point in the forward direction to a detector 13 and a distance 41 from a print starting point in the reverse direction to a detector 14. Then driving in the forward direction is started to find an actual distance for the distance 31 on the basis of a time point when the detector 12 passes the detector 13. Similarly, driving in the reverse direction provides an actual distance for the distance 31. Then displacement errors are found from the set distances 31 and 41 and the respective actual distances, so that if an error is positive, p is corrected so as to render the error zero, and if an error is negative, q is corrected.

Title: Wall hole closing device
Inventor: KATSUURA NOBUO
IPC: F16L5/00
Filed: 1997-05-29
Abstract: PROBLEM TO BE SOLVED: To improve workability even by one person and to prevent falling of chipped powder of a gypsum board even on a collapsible wall hole by providing a means to engage a plural number of elastic blade pieces to press the wall hole on a hole closing main body in a diametrically contracted state and a means to release them from the diametrically contracted state. SOLUTION: An elastic blade piece 4 in a diametrically contracted state and a projected piece 11 are inserted into a wall hole after passing a fixed band through a band installing part. After inserting them, when a clamp fin 17 is released from a storage part 12 by pushing a click 18 for fixing on the inside through a through hole from the outside by a screwdriver, etc., the elastic blade piece 4 is elastically restored, pressed on the wall hole and a wall hole closing main body 1 is temporarily fixed. At this time, as diametrical contraction is released after a cover part 2 is pushed in until it makes contact with a wall surface in a state where the elastic blade piece 4 is contracted in diameter, the elastic blade piece never interrupts insertion and the cover part 2 is neither returned by elasticity.  Additionally, it is possible to prevent chipping of a gypsum board and falling of its powder at the time of insertion.

Title: Picture producing device
Inventor: SAEKI SHINICHI
IPC: G06T15/80
Filed: 1986-07-01
Abstract: PURPOSE:To reduce arithmetic quantity needed for production of picture element and to produce pictures at a high speed, by dividing a picture according to the difference of luminance to produce the luminance of picture elements at the end points of those divided picture areas respectively and interpolating the luminance of all picture elements within the areas by the luminance of the picture elements at said end points. CONSTITUTION:A picture area dividing part 1 divides a produced picture into oblong picture areas having the same luminance of picture elements. A picture element luminance producing part 2 produces the luminance of the picture elements of the key point of each picture area. An intra-picture area interpolating part 3 obtains the luminance of all picture elements in each picture area through interpolation of the luminance of the key point to store it in a frame buffer 4 and reads data out of the buffer 4 to display them at a display part 5. Thus the picture is divided into the number of areas much smaller than all picture elements of the produced picture. Therefore the picture element producing calculation frequency can be reduced and pictures are produced at a high speed.
