Title: Signal recording stamper
Inventor: NANBA SHIYOUICHI
IPC: G11B9/06
Filed: 1983-12-20
Abstract: PURPOSE:To facilitate a transcription of signals by forming a record signal into a trapezoid having the ratio between upper and lower side set larger than the specific value. CONSTITUTION:The ratio between upper and lower sides of a trapezoidal signal 5 is set at >=1.5 for a stamper 2. Such a stamper 2 is used to transcribe signals. In this case, the flow of resin is facilitated with the satisfactory margin secured for molding conditions. Furthermore, no dislocation nor strain are produced to the signals at the disk side. Then a laser is irradiated to the signals through a disk produced by transcription, and the signals are reproduced by the reflected laser light. In such a case, the reflected light quantity given from the signals are increased as compared with a case where the signal has an oblong form. Thus the electric characteristics can also be improved.

Title: Mixed flow fan
Inventor: TOMINAGA TETSUO
IPC: F04D23/00
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To improve boosting performance and reduce assembling man-hour by elongating main plate and side plate of an impeller by a prescribed length from the discharge side of a vane and making a rotary diffuser. SOLUTION: A rotary diffuser 20 is constituted by elongating each of a main plate 1 and a side plate 2 of an impeller F to the downstream side from a discharge side 3a of a vane 3 and obliquely by a prescribed length in the outside diameter direction. In this case, when the impeller F is driven by a motor 5 via a drive shaft 6, the speed component is converted into pressure in a process that air flows in the rotary diffuser 20 after air is sucked into the impeller F from the suction port 15 through an air passage 14 and air is energized by the vane 3 and subsequently air is blown out within a chamber 4. Because the speed component is converted into pressure in a process that gas flows in the rotary diffuser 20, pressure loss of the exit of the impeller F is reduced.

Title: Spindle
Inventor: KONDO HIDEO
IPC: B23B31/117
Filed: 1991-08-28
Abstract: PURPOSE:To prevent the vibration and fretting of a spindle, in the spindle of a machining center or the like, by arranging cushioning members in the respective clearances caused between the apex parts of respective paired disk springs and the inner circumferential surface of the spindle. CONSTITUTION:For instance, rubber-made ring-shaped O-rings 3 as a cushioning member are fitted on the head-shaped apex parts 2A of respective disk springs 2. Thereby, the O-rings 3 abut on the inner circumferential surface 1a of a spindle 1, and the wave-form buckling of respective disk springs 2 caused by the operation of a drawbar 12 is absorbed by the deformation of the O-rings 3 themselves, so that the abutting condition can be maintained. Thus, the disk springs 2 can be prevented from directly being brought into contact with the inner circumferential surface 1a.

Title: Catalytic reaction method and apparatus
Inventor: ASO YOSHIYUKI
IPC: B01D53/86
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To always cary out a satisfactory catalytic reaction regardless of a reaction temp. range by passing unreacted gas through the space between catalysts into which an electric discharge electrode is inserted to excite or ionize the same by electric discharge and allowing excited or ionized molecules to impinge against the surfaces of the catalysts to activate the catalysts. SOLUTION: Unreacted gas 2 is passed through the space 4 between the catalysts 3 within a reaction container l and electric discharge is performed in the space 4 by an electric discharge electrode 5 to excite or ionize the unreacted gas. Excited or ionized molecules are allowed to impinge against the surfaces of the catalysts 3 to activate the catalysts 3 to advance chemical reaction and the reaction gas 8 is discharged. At this time, there is activation temp. in the catalysts 3 because activation energy becomes little by catalytic action but does not become zero. Therefore, by exciting or ionizing reduced activation energy by electric energy, energy corresponding to heat energy exceeding 1,000 deg.C can be simply applied.
