Title: Steel wire for spring
Inventor: OISHI YUKIHIRO
IPC: C22C38/00
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To suppress dispersion of free length in machining of a spring by satisfying two indexes correlated with spring free length and its shift average by means of residual stress in a plurality of positions on a steel wire surface. SOLUTION: Residual stress is measured in plural positions as to at least one in the circumference direction, the longitudinal direction, and the diameter direction of a steel wire, for example, in four positions in the circumference direction of the steel wire, and this measurement is carried out in three positions in the axial direction respectively, and then, it is determined whether the data of residual stress σ in 12 points in total satisfy at least one relationship for the following indexes (a), (b) or not. The index (a) satisfies the following expression: σmax-σmin <=25kg/mm<2> (σmax represents a maximum value of residual stress while σmin represents a minimum value of residual stress.) The index (b) satisfies the following expression: √[(Σσn<2> - (Σσn)<2> /n})/n] <=10kg/mm<2> . When these relationships are satisfied, dispersion of free length in machining of a spring can be suppressed effectively.

Title: Tape printer
Inventor: TAKEUCHI YOSHIYUKI
IPC: B41J11/66
Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To prevent positional shift at the time of tape feed or tape cut by an arrangement wherein a control means sustains a stepping motor, stopped during the cutting operation of a tape cutting means, in excited state. SOLUTION: A printing mechanism 40 comprises mechanical components, i.e., a thermal head 11 and a stepping motor 41, and electric components, i.e., a print control gate array 42 and a motor driver 43. The printing mechanism 40 is connected with a CPU 21 which controls the feeding of a tape T by driving the stepping motor 41 by a predetermined number of steps at a time in synchronism with the single dot line printing by the thermal head 11. When the tape T is cut off by means of a cutter, the stepping motor 41 is sustained in excited state while stopping the rotation. According to the arrangement, positional shift can be prevented at the time of tape feed or tape cut.

Title: Manufacture of semiconductor device
Inventor: IZAWA KOTARO
IPC: G03C1/74
Filed: 1987-01-27
Abstract: PURPOSE:To form a flat light-sensitive resin film without shades at a step part in the coated state on the surface of a semiconductor substrate, by dissolving the light-sensitive resin once applied on the semiconductor substrate again with a soluble solvent, and thereafter evaporating and drying the solvent so that the flatness is kept with the surface tension of the dissolved liquid. CONSTITUTION:A resist-applied semiconductor substrate is exposed in supersaturated vapor 8 of a solvent. The supersaturated vapor 8 is obtained by dropping the solvent on an ultrasonic wave vibrating plate or by a subcooling method of vapor yielded by heating. The dew of the solvent is condensed on the surface of the resist film, which is exposed to the supersaturated vapor 8 of the solvent, and the resist film is dissolved 9 again. At this time, irregularities in thickness of the resist film disappeares. The semiconductor substrate, whose resist film on the surface is dissolved, is put into a constant temperature oven, and the solvent is slowly evaporated and dried 10. At this time, the resist film 9, which is dissolved again, is dried with the surface tension being kept. Therefore, a flat resist film 11 is formed on the surface of the semiconductor substrate. The shade of the resist in a recess part in the coated state disappears.

Title: X-ray source apparatus

IPC: H01J35/18
Filed: 1983-02-08
Abstract: PURPOSE:To realize the exposure by X-ray with a good resolution by a high through-put by providing two or more X-ray extracting windows for two or more X-ray sources from the line or plane. CONSTITUTION:The surface of water cooled target 1 is irradiated in the vacuum condition by the electron beam 2 scanned in the X-Y directions and thereby two or more X-ray sources are generated. Corresponding to these X-ray sources, two or more Be windows 3 are formed in such a manner as being given to a supporting plate 4 made of a material which rejects X-ray such as a copper or silver, etc. With the structure where the X-ray from the X-ray source is extracted from two or more windows, the X-ray exposure having a high resolution can be realized by limiting spread of X-ray even if amount of X-ray from the X-ray source is limited and even if a distance of an object to be irradiated from the X-ray source is curtailed. Moreover, since the throughput of exposing process can be determined by adverse proportion of square of distance from the X-ray source, high throughput can be obtained.

Title: Magnetic driving type electrode for vacuum interrupter
Inventor: NODA TAIJI
IPC: H01H33/66
Filed: 1989-01-31
Abstract: PURPOSE:To improve the breaking performance by setting the outer diameter of a content surface less than the diameter of a lead rod, setting the radius of the contact surface smaller than the radius of a contact member itself by more than 1mm, and setting a component of the crossing direction of current ways formed between the contact surface and the lead rod at the time of energization to be larger than a compo nent of the parallel direction to the contact surface. CONSTITUTION:A contact part 28 having a ring-like contact surface 28a is engaged in a throughhole 22 on the surface side of an arc part 21. At the contact part 38, an outer diameter D2 of a contact surface 28a is smaller than an outer diameter D1, and a difference between their diameters l(=(D1-D2)/2) is more than 1mm. This means that the contact surface 28a is formed to protrude in the surface of the contact part 28 through a taper. The outer diameter D2 of the contact surface 28a is of a size less than an outer diameter d1 of a lead rod 25. Most of current ways between the lead rod 25 and the contact surface 28 are of the crossing direction to the contact surface 28a at the time of energization and just after opening, so arc spreads radially by force of self-diffusion of metal steam produced at the time of breaking and moves from the contact part 28 to the arc part 21 to be extinguished after rotation and moving by action of spiral grooves 23.
