Title: Ventilating device
Inventor: NAKAGAWA NAOHARU
IPC: F24F9/00
Filed: 1984-01-25
Abstract: PURPOSE:To eliminate possiblity of freezing even on a cold land or the like in winter and permit heat exchange ventilation at all times by a method wherein an element is supported about the rotary shaft thereof and a rotating means, rotating the element, is provided in the device. CONSTITUTION:The ventilating device 10 is provided with a circular rotary partitioning plate 12 in the tubular element 11 in order to partition the element into upper and a lower divisions. The partitioning plate 12 is fixed to the rotary shaft 14 rotated by a motor 16. The ventilatig device 10 is provided on the boarder of the inside R and the outside S of a room and when fans 25, 25' and the motor 16 are rotated, cold air of outside of the room is sucked from an air feeding port 22 and is discharged into the room from an air discharging port 23 through the small chamber U of the element 11 at the upper side thereof. When the heat pipe near the outside of the room is frozen, the partitioning plate 12 moves gradually to a position where the warm-air in the room is hitting since the partitioning plate 12 is being rotated, and whereby the freezing of the heat pipe may be dissolved.

Title: Pseudo halftone processor
Inventor: FUKUDA HARUO
IPC: G06T5/00
Filed: 1993-01-28
Abstract: PURPOSE:To improve the tracking performance of an original picture to a density change and the gradation by applying different weighting to a multi-value picture signal and a binary picture signal when weighted luminance is calculated and making a reference picture element range of a multi-value picture filter narrow. CONSTITUTION:Corrected picture data outputted from an adder 23 are inputted to a correction multi-value picture buffer 25 and a comparator 24. The comparator 24 compares the signal with a threshold level of a threshold level generating section 27 to binarize it and outputs the result to a binary picture buffer 20. A binary picture filter 31 calculates the luminance of the binary picture in the unit of picture elements based on an output of the buffer 30 and an output of a recording dot coefficient setting section 28 to execute weighted addition. Furthermore, a multi-value picture filter 26 implements the weight addition of the luminance of the corrected picture stored in the buffer 25. Then coefficients used for weight addition of the filters 31, 26 are made different and the picture element range referenced by the filter 26 is made narrower than the picture element range referenced by the filter 31. Thus, the tracking performance of the original picture to a density change is improved and the gradation is enhanced.

IPC: H04R29/00
Filed: 1992-01-28
Abstract: PURPOSE:To prevent the occurrence of a throb sound without detracting the freedom sense of a driver with simple structure by providing a control means for controlling a drive means so as to operate a slide roof panel of an assistant seat in a closed direction when the throb sound is detected. CONSTITUTION:A throb sound is detected with a throb sound detecting means when slide roof panels 12L and 12R on a driver's seat side and an assistant seat side are also, in an open condition and the throb sound occurs. This causes a control means to control a drive means so as to operate the slide roof panel 12R on the assistant seat side in the closed direction, and air is not flowed into from a roof opening part 10 on the assistant seat side where an opening length of a roof opening part is shortened. Therefore the resonance of Helmholtz is unoccurring not to cause the throb sound because the air, flowed into from the front side of the roof opening part 10 on the driver's seat side, is flowed out from the roof opening part 10 on the assistant seat side and is not flowed out from the rear side of a roof opening part.

Title: Rotary compressor
Inventor: YANASE SEIGO
IPC: F04C29/12
Filed: 1988-01-25
Abstract: PURPOSE:To improve assembly workability by providing two or more reed holding seats in a position opposed facing to a reed, spring holding part on the reed holding seat and a coil spring to be arranged. CONSTITUTION:A compressor, providing a reed holding seat 27 in a position opposed facing to a reed 25 and a spring holding part 31 on the reed holding seat 27, provides a coil spring 26 to be arranged between the reed 25 and the spring holding part 31. This coil spring 26 sets its free length to a range in which the coil spring 26, when it is inserted into the spring holding seat 27, prevents a tightening part of the spring from protruding from the end face of a cylinder 5. Thus placing the reed 25 in a position of or lower than the end face of the cylinder 5 in the time of assembly, assembly workability improves because the reed 25 can be prevented from its falling off and displacement.
