Title: Iron
Inventor: NAKAMURA SHUNEI
IPC: D06F75/38
Filed: 1996-06-25
Abstract: PROBLEM TO BE SOLVED: To prevent an adverse influence upon a heater, to prevent an ironing face member from being damaged and to improve sliding property by providing a base member to be heated by the heater and the ironing face member to be coupled on the lower face side of the base member by forming a compound plating film distributedly containing fluorine compound particles. SOLUTION: A main body 1 of an iron has a base member 3 to be heated by a heater 2 embedded at the time of molding due to clicast and on the surface of the base member 3, an ironing face member 4 forming the compound plating film distributedly containing fluorine compound particles is coupled by screws 7 etc. Thus, the plating film is not stuck at the terminal section of the heater 2, and danger to generate the insulation degradation of the heater 2 in the process of compound plating filming can be eliminated. Besides, since the compound plating film is constituted into matrix uniformly distributing the fluorine compound particles in a transition metal, hardness can be extremely improved and wear resistance can be improved.

When drilling, first pointed sharp edges OR, OR1 cut in, and, then, cutting is started at the parts RP, RP1 of the secondary cutting edges 8, and continued by the cutting edges 2 and thus, a cutting process proceeds. Chips are discharged at the QP part of the secondary cutting edge 8, spirally bent being hit on the side wall 5 of a chip pocket 4 and continuously discharged, preventing wear due to frictional heat. Also, since a pointed sharp edge part, whose top is the center of rotation, is formed by providing second faces 6 and third faces 7 from a pair of cutting edges toward their heels, the cutting-in into a workpiece and centripetalism, as well as drilling accuracy can be improved.

Filed: 1991-07-04
Abstract: PURPOSE:To provide an air-conditioner which reduces the generation of noise and has the excellent quality of sound, in an air-conditioner having a heat- exchanger and a cross fan. CONSTITUTION:An air-conditioner comprises a suction port 12, a discharge port 13, a cross fan 15 located in a ventilation flue 14, 7 and a heat-exchanger 21 on the upper stream side of the cross fan 15 in the ventilation flue 14.

The flow of suction air flowing in the heat-exchanger 21 and collided with the heat transfer pipe 20 is sucked by means of a negative pressure generated by a negative pressure generating part 19 of the heat transfer pipe 20. Since the air flows along the heat transfer pipe 20 without the occurrence of peel at the rear part of the heat transfer pipe 20 and no turbulence is produced at a wake flow, the generation of noise owing to turbulence of a flow can be reduced.

Title: Etching method for thin gold film
Inventor: HIRAISHI MASANORI
IPC: C23F1/30
Filed: 1981-10-14
Abstract: PURPOSE:To etch a thin gold film easily, by immersing the thin gold film vapor- deposited on a substrate into an aq. hydrochloric soln. of a concn. higher than specified. CONSTITUTION:The thin gold film of about <=1,000Angstrom  vapor deposited on a substrate such as a biaxially oriented polyester film that withstands hydrochloric acid by avacuum deposition method or the like is immersed in an aq. hydrochloric soln. of >=0.5wt%, more preferably about 1-10% concn., whereby the thin gold film is etched easily. According to this method, there is no need for using any special vessel, the generation of toxic gases is little, the treatment of waste liquid is easy, and the finishing of etching is good. It is possible to accelerate the etching by stirring the etching soln. at a high speed during immersion or heating or spraying the same. Even if the thin gold film remains after the immersion, the film is vulnerable to peeling and is therefore removed easily with gauge or the like.

Title: Rotary type magnetic recording and reproducing device
Inventor: MINO TETSUYA
IPC: G11B5/596
Filed: 1983-09-07
Abstract: PURPOSE:To enlarge the permissible extent of a sensor for detecting reference track so that an imperfection in reference track detection at the time of multiple rotation can be offset, by providing a track which is exclusively used for reproduction at the outer periphery of a reference track for detecting the reference track. CONSTITUTION:A reproduction only track 11 is installed to a track which is one-track outside of the outermost reference track 10. No recording is performed on the reproduction only track 11 and no reproducing signal 21 is outputted to the track 11. At tracks other than the reproduction only track 11, pulse outputs 20 are generated from a comparator circuit 17 at a cycle determined by magnetization reflecting intervals. Since no pulse output is generated from the comparator circuit 17 at the reproduction only track 11, the output 22 of a retrigger-one shot circuit 18 becomes false one at the track 11. When the signal of a reference track detecting sensor is detected at the time of power supply making, a head is moved to one-track outside track and whether or not the track is the reproduction only track is judged by discriminating the realness and falseness of the output of the circuit 18. When it is discriminated that the track is not the reference one, the reference track is detected by moving the track to further outside.

IPC: H01L27/14
Filed: 1988-06-30
Abstract: PURPOSE:To not only prevent a foreign matter from merely adhering but to improve the function of a protective mask by fusion-bonding jumping adhering matter by coating a foreign matter protective region of a CCD lid with protective mask substance having high softening point in reaction with sealing glass at sealing glass seizing temperature, then coating it out of the protective region with the glass, baking it to seize it, and then removing the mask substance. CONSTITUTION:Protective mask substance contains, for example, crystal powder as solid content, nitrocellulose as resin, paste made of ester and terpene as solvent, and the protective region of a CCD lid is coated with the paste. Thereafter, it is coated by printing on a region out of the protective region with sealing glass paste, and baked to match the seizing temperature (340-450 deg.C) of the glass. The resin, solvent of the substance are vanished by the baking, jumping adhering matter is fusion-bonded to the surface of the mask to become only solid content. Thus, it is roughly cleaned from the CCD face with nylon brush and further washed with water to be easily removed.

Filed: 1986-07-14
Abstract: PURPOSE:To prohibit unnecessary high speed revolution of a simple planetary gear set by placing the third clutch between an output shaft and a carrier of the second simple planetary gear set, in a gear transmission device for automobiles. CONSTITUTION:The selective operation of 1st-3rd clutches 42, 44, 46 and 1st-3rd brakes 48, 50, 52 can provide four advance- and one reverse gearshifts, through the intermediary of 1st-2nd simple planetary gear sets 38, 40. Further, the second simple planetary gear set 40, when subjected to the unloaded condition without being involved in determining output revolution, releases the engagement of the carrier 64 of the second simple planetary gear set 40 with an output shaft 36 by the third clutch 46. Thus, each gear and so on of the second simple planetary gear set 40 can be prevented from developing its high revolution for determing the output revolution.
