Title: Manufacturing method of spring
Inventor: TAKANO MASAYOSHI
IPC: C21D8/00
Filed: 1979-05-16
Abstract: PURPOSE:To manufacture a spring superior in settling resistance and high in fatigue strength, by producing band steel through cold rolling and annealing at temperature below A1 transformation point of alloy steel containing C, Si, Mn, Cr and Fe at a specific rate. CONSTITUTION:Alloy steel used for this purpose contains C; 0.55-1.0%, Si; below 0.25%; Mn; 0.3-1.30%, Cr; 0.15-1.0% and Fe; the rest, with conditions K=C<2/1> (1+0.64Si)(1+4.1Mn)(1+2.3Cr)>=6. The steel undergoes, once at least, cold rolling with a rolling rate of 5-60% and annealing at temperature below the A1 transformation point to produce band steel which also undergoes heat treatment to get hardness of Hrc 40-53 before or after its machining. Since the alloy steel contains below 2.7% of Ni and/or 0.30% of Mo, stability against heat treatment and fatigue strength can be improved.

Title: Digital fluorography device
Inventor: ASAHINA HIROSHI
IPC: H05G1/64
Filed: 1988-03-12
Abstract: PURPOSE:To make it possible to set the optimum photography tube voltage speedily constantly by using an output of a multiplier phototube of an optical system directly instead of a video signal of a TV system and forming a relational expression by performing a test sequence to change a pulse width. CONSTITUTION:In the first constitution, a testing pulse X-ray having a predetermined pulse width is applied to a multiplier phototube 19 provided in an optical system 18 to determine a photography tube voltage with which this output becomes the optimum. The thickness of a subject matter is determined by a relational expression based on this voltage, and the optimum photography tube voltage is determined when a digital fluorography is used. In the second constitution, the test sequence is performed changing the pulse width of the testing pulse X-ray in the first constitution proportionately to the change of the pulse width when the digital fluorography is used, and a relational expression is formed between the thickness of a subject matter and a photography tube voltage. The optimum value can thus be determined if there is any change in the pulse width in the SPI mode.

Title: Louver setting structure for ventilator
Inventor: MIKI HIROYUKI
IPC: B60H1/34
Filed: 1984-03-29
Abstract: PURPOSE:To aim at a significant improvement in a working property for assembling parts and the promotion of unnecessariness for accuracy in a contact surface, by forming a notch, where a pivot for a louver is set up, with a slotted circular shaft holding part and an open end part being somewhat smaller in width than the shaft holding part and than a diameter of the pivot. CONSTITUTION:Notches 25a-28c, 25a', 25c', 26a-26c, and 26a'-26c' are all formed out of a slotted circular shaft holding part A and an open end part B installed in succession with the shaft holding part, while width l' of the open end part B is made up somewhat smaller than a diameter phi' of the shaft holding part A. Each diameter of pivots 21a-21c, 21a'-21c', 22a-22c and 22a'-22c' is larger than the width l' and formed into a value making it insertable into each shaft holding part A free of rotation. Therefore, only when each pivot of louvers 13a-13c and 15a-15c is set up inside the notched shaft holding part, each louver is preventable from coming off a housing member and, what is more, contact surfaces themselves of a pair of housing members is no longer required to make them coherent with accuracy in order to eliminate lost motion in a direction of these contact surfaces 6 and 7 of the pivot, thus dispensing with troublesomeness for highly accurate machining.

Title: Semiconductor device
Inventor: YOSHINO HIDEO
IPC: H01L21/316
Filed: 1985-03-26
Abstract: PURPOSE:To prevent the occurrence of cracks and to improve the resistance to humidity, by composing a passivation film of two layers, the lower layer of which is formed of a material containing an impurity in a high concentration and having an effect of relaxing stress and the upper layer of which is formed of a material containing an impurity in a low concentration or not containing it. CONSTITUTION:After the formation of a second wiring layer 13, a high- concentration PSG film 15 is first formed to be 2,000-5,000Angstrom thick as the lower layer. Subsequently, a low-concentration PSG film 16 is formed thereon as the upper layer. A thickness of this upper layer 16 is determined to be a value obtained by subtracting the thickness of the lower high-concentration PSG film 15 from a desired thickness for a passivation film. Preferably, a ratio of the thickness of the high-concentration PSG film 15 to the total thickness of the passivation film (the total of the upper and lower layers) is generally 30-50%. The PSG film 15 containing an impurity in a high concentration has a lower hardness and therefore has an effect of relaxing stress. The PSG film 16 containing an impurity in a low concentration has an excellent resistance to humidity.
