Title: Manufacture of mass of germanium dioxide-diantimony trioxide glass
Inventor: TAKAHASHI HIROSHI
IPC: G02B6/00
Filed: 1981-08-06
Abstract: PURPOSE:To obtain transparent glass not causing crystallization in spite of the low Sb2O3 content by sintering a porous deposit of GeO2 and Sb2O3 formed by flame hydrolysis. CONSTITUTION:GeCl4 and SbCl5 are heated and bubbled with an inert gas to generate satd. vapor of GeCl4 and SbCl5 in the gas. This gaseous mixture is introduced into an oxyhydrogen flame to cause flame hydrolysis. By depositing the resulting fine powder of a GeO2-Sb2O3 mixture, a porous mass is formed. The mass is converted into transparent glass by sintering. Thus, transparent glas not causing crystallization in spite of the very low Sb2O3 content is obtd.

Title: Pneumatic tire with v-directional, low and inclined groove
Inventor: NAKAGAWA MASAO
IPC: B60C11/04
Filed: 1995-05-22
Abstract: PURPOSE: To lower the noise by chamfering at least a prescribed area (given in terms of percentage of a pitch in the circumferential direction of a directional, low, inclined groove) of the surface of a letter-V-shaped center block in such a manner that the depth of chamfering becomes shallower from the convergent tip part of the letter-V toward wide width part before the tire is inflated by internal pressure, thereby making the level of the chambered surface become equal to that of the surrounding surface when the tire is inflated. CONSTITUTION: Before a tire is inflated by internal pressure, the surface of a letter-V-shaped center block is chamfered, ranging over an area 4 of more than 40% (preferably 70%) of a large pitch (P), or a circumferential space of a directional, low, inclined groove 1. The depth of chamfering becomes gradually shallower from the convergent tip end of the letter-V toward wide width part. When the tire is inflated by internal pressure after the tire is assembled with a rim, the level of the chamfered surface of the letter-V-shaped center block 3 becomes almost equal to that of the surface of the surrounding block, as shown by a double-dot-and-dash line of an A-A section. With this, the uniformity level is drastically improved, and moreover the tire noise can be lowered.

Title: Continuous production of substrate for optical recording medium
Inventor: SANTO TAKESHI
IPC: G11B7/26
Filed: 1989-05-18
Abstract: PURPOSE:To reduce times of changing roll stampers in a continuous production process of substrate having guide grooves comprising UV-curing resin by transferring surface patterns of a stamper to UV-curing resin provided on the substrate and then releasing the hardened UV-curing resin from a roll stamper. CONSTITUTION:Immediately after the roll stamper 3 and the substrate 1 come into contact to each other, the both side edges of the substrate are irradiated with UV ray focused along each edge to harden the UV-curing resin 5 which is spread to the irradiation area. Then the whole UV-curing resin is irradiated with UV-ray to be hardened. Thereby, times of changing roll stampers 3 can be reduced in the continuous production process of the substrate 1 having a fine pattern for guide grooves and/or information comprising UV-curing resin. Moreover, dust due to bur of resin can be prevented from sticking on the sub strate surface.

Title: Aligning mark for electron beam exposure
Inventor: KOBAYASHI KOUICHI
IPC: G03F9/00
Filed: 1984-04-09
Abstract: PURPOSE:To prevent the deterioration of the mark detecting precision by a method wherein the aligning mark with a step difference part is made of a material of a density smaller than that of the material being used for the substrate. CONSTITUTION:A reflected electron signal reflected from a high-density material, such as gallium arsenide, gold, silver, molybdenum and so forth, undergoes a large fluctuation in the amount of reflected electrons due to the roughnesses of the materials. Therefore, the fluctuation of the reflected electron amount changes largely not only in the edge part of an aligning mark but also in the other parts of the mark. As a result, the S/N is lowered. Thereupon, the surface of an aligning mark part 11 consisting of a high-density material is contrived so as to coat with a coated film 12 made of a low-density material, such as silicon, silicon dioxide, aluminum and so forth. When such an aligning mark is formed, the S/N is sufficiently improved.

Title: Water level detector for dish washer

IPC: A47L15/42
Filed: 1989-05-17
Abstract: PURPOSE:To supply the optimum quantity of water as the load of an washing pump by detecting gradient for the output voltage of a noise removing means at suitable time intervals and opening or closing an water supply valve by the output of an water level judging means when a ratio between the value of set initial gradient and the value of the detected gradient reaches to specified magnification. CONSTITUTION:When the output voltage of a noise removing means 12 exceeds a voltage V2, a changed part dv for the output voltage of the noise removing means 12 is measured at fixed time intervals dt and a value, for which the dv is divided by the dt, is defined as sampling gradient kt and outputted to an water level judging means 16. The water level judging means 16 recognizes a value, for which the sampling gradient kt is divided by initial gradient ko, as magnification (p) and monitors whether the magnification reaches less than a certain value p1 set by a user in advance or not. At a moment when the magnification reaches the p1, it is recognized that an water level arrives at a suitable value. Then a signal is outputted to an water supply valve driving means 17. The water supply valve driving means 17 receives the signal and opens the water supply valve. When the output waveform of the noise removing means 12 is periodically fluctuated, a filter for the leavings is clogged. Accordingly, the periodical waveform is detected by a periodical waveform detecting means 19 and it can be notified by a filter notifying means that the filter is clogged with the leavings.
