Title: Heat sink for electronic module
Inventor: SHINODA YUKITOSHI
IPC: H05K7/20
Filed: 1993-12-24
Abstract: PURPOSE:To reduce difference in temperatures between an enclosure air outlet duct side and an enclosure air inlet duct side of a heat sink base face by providing on a heat sink a second flow path where cooled air flows in a reverse direction to a first cooled air path. CONSTITUTION:A partition 6 for vertically dividing a heat sink 3 is provided to make a first flow path so that cooled air 5 flows from an enclosure air inlet duct 1 to an enclosure air outlet duct 2. On the other hand, a second flow path is provided so that the enclosure air 5 flows from an enclosure air inlet duct 1a to an enclosure air outlet duct 2a in a reverse direction to that of the first flow path. Thus the cooled air 5 flowing in vertically adjacent flow paths exchange heat with each other, so as to reduce difference in temperatures on the base face of the heat sink 3.

Title: Image forming device
Inventor: SATO HIROSHI
IPC: G03G15/02
Filed: 1991-11-20
Abstract: PURPOSE:To provide an image forming device capable of suppressing the vibration of a body to be charged without occurring image deterioration such as image flowing and lowering charging sound even in the case of setting the frequency of A.C. voltage impressed to a conductive member at high. CONSTITUTION:A column 20 constisting of an urethane rubber having <=10W/mk heat conductivity is packed into a photosensitive drum 3 (a body to be charged) in contact with the inner surface of the photosensitive drum 3. Resonance of the photosensitive drum 3 is suppressed, since the weight and rigidity of the photosensitive drum 3 is heightened by the column 20 to heighten characteristic frequency, thereby the charging sound is lowered even if frequency of A.C. voltage impressed to an electrifying roller 4 (a conductive member) is setted at high. And, since the column is constituted of the urethane rubber having small heat conductivity, the increase of heat content of the photosensitive drum 3 is suppressed, the generation of dew-condensation on the surface of the photosensitive drum 3 is prevented, and the lowering of surface resistance of a photosensitive layer 3b due to moisture is suppressed to prevent the occurrence of image deterioration such as image flowing, and the image excellent in quality is stably obtained.

IPC: B41J29/08
Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To support an acoustic material without relying upon adhesion and to enhance sound absorption effect of the acoustic material. SOLUTION: The support for acoustic material comprises a wall face 9 made of an elastically expanding/shrinking material and applied with an acoustic material 8 having cuts in the thickness direction thereof, and supporting protrusions 11 projecting from the wall face 9 by a length shorter than the thickness of the acoustic material 8 and fitted in the cuts 10 of the acoustic material 8. The cuts 10 are enlarged when they are fitted with the supporting protrusions 11, and the supporting protrusions 11 are compressed by the acoustic material 8 through reaction and attached to the wall face 9 without relying upon adhesion. Consequently, sorting work is facilitated at the time of recycling.  Furthermore, sound absorbing effect can be enhanced because the forward end of the supporting protrusion 11 does not project from one side of the acoustic material 8 and the wall face 9 is covered with the acoustic material 8 together with the supporting protrusions 11.

A channel selection part 106 selects the main channel or the sub-channel in accordance with the control signal outputted from the control part 102 and outputs a signal inputted through a sound input part 104. On the other hand when the dubbing flag is detected at the time of reproducing, the sub-channel is automatically selected and a recorded sound signal is outputted. When a dubbing flag can not be detected, the sound signal of the main channel is outputted again.

Title: Sif signal processing circuit
Inventor: HATANO HIROYUKI
IPC: H03L7/193
Filed: 1995-12-20
Abstract: PROBLEM TO BE SOLVED: To allow the processing circuit to use only one oscillator or to receive an external referece signal. SOLUTION: The SIF(single intermediate frequency) processing circuit applies FM demodulation to an SIF signal having a carrier with a frequency difference between a video IF carrier and an audio IF carrier in a stage of the same carrier frequency brought further into a low frequency, regardless of a broadcast system. A PLL circuit 23 to convert the frequency of the SIF signal into lower is provided to the processing circuit, an output of the PLL circuit 23 and the SIF signal are mixed, and the output of the PLL circuit 23 is varied with the broadcast system. Since the plural frequency signals are outputted simply by controlling a frequency division ratio of a frequency divider 25 of the PLL circuit 23, one oscillator is enough for, e.g. a reference oscillation signal.

Abstract: PURPOSE: To improve the superposing matching means of the color image of a recirculation type color printer. CONSTITUTION: This device is provided with two pairs of spacing pulleys where a conveyer belt 16 carrying a sheet to a transfer area is arranged around of them and a pair of outside idler pulleys 30A.

Title: Electrode material of low-frequency treatment device or the like
Inventor: SHIKINAMI YASUO
IPC: A61N1/04
Filed: 1988-12-29
Abstract: PURPOSE:To obtain the electrode material having an excellent electrical conductivity while maintaining the pliability by tightly adhering an ion-conductive tacky adhesive agent to the front surface of a non-woven carbon fabric and sticking a soft foam to the rear by means of an adhesive agent. CONSTITUTION:The electrode material 1 is formed by tightly adhering the ion-conductive tacky adhesive agent 2 to the front surface of the non-woven carbon fabric 3 and sticking the soft foam 4 to the rear by the adhesive agent 3. The non-woven carbon fabric having 10 to 200g/m<2> METSUKE is usable as the non-woven carbon fabric 3 to be used. The fabric which is too coarse in mesh is poor in the electrical conductivity. Conversely, the fabric which is excessively dense in mesh and has high rigidity is inadequate. A soft polyvinyl chloride foam, 1,2-polybutadiene foam, ethylene/vinyl acetate copolymer foam, etc., are adequately usable for the soft foam 4. Any foams of rubber and plastic systems are usable as the foams as far as the foams are soft. The ion-conductive tacky adhesive agent 2 which has the good tackiness and electrical conductivity stable for a long period of time is used. Electrical energy passes the non-woven carbon fabric 3 having the excellent electrical conductivity and transfers to the ion-conductive tacky adhesive agent 2 stuck tightly to the body surface. The uneven in the conduction performance is obviated and the degradation in the tacky adhesive performance is entirely obviated.
