Title: White bismuth oxide composition
Inventor: ABE ISAO
IPC: C01G29/00
Filed: 1990-04-19
Abstract: PURPOSE:To improve thermal stability by producing fine particles having a composition shown by a specified empirical formula and having respectively prescribed average particle size, whiteness and yellowness. CONSTITUTION:Sulfuric acid is added to a Bi(NO3)3 solution prepared by dissolving BiCl3 in nitric acid in an amount of 0.16-0.47 equivalent based on Bi in the solution. The solution is then neutralized to pH7-9 using ammonia to generate a precipitate and the generated precipitate is separated and dried. The dried precipitate is subsequently calcined at about 500 deg.C, thus obtaining the objective white bismuth oxide composition having 0.5-10mum average particle size, a composition represented by the formula (1.08<=x<=1.369), >=93 whiteness and <=11 yellowness.

Title: Method for recovering iron powder from converter dust
Inventor: MISAKI NORIO
IPC: B22F9/02
Filed: 1986-05-06
Abstract: PURPOSE:To easily recover iron powder of a high grade by drying coase-grained dust separated from the dust collection water of the dust generated by a converter then classifying, separating and magnetically separating extremely small sizes, and treating the same with strong hydrochloric acid, then drying the powder in a nonoxidative atmosphere. CONSTITUTION:The dust generated from the converter is subjected to wet dust collection and the coase-grained dust 2 sized about >=40mum grain size is settled by a settling and separating pit from slurry dust 1 in the water. Said dust is preferentially removed and taken out of a removing port 3. After the separated coarse-grained dust 2 is dried, the sizes of <=500mum grain size are classified and separated. The dust sized <=500m is magnetically separated so that nonmagnetic materials are separated therefrom to some extent; thereafter, the dust is treated with 1-10N aq. hydrochloric acid by which the surface sticking layer of the iron powder is thoroughly removed. After the iron powder is separated by filtration, the iron powder is dried at about 25-100 deg.C in a nonoxidative atmosphere such as N2, Ar, or CO2 and is finally magnetically separated. The high-grade iron powder which is free from work strain and does not contain impurities is thus obtd.

Title: Air-conditioner for motor vehicle
Inventor: KOJIMA YASUSHI
IPC: B60H1/00
Filed: 1982-06-17
Abstract: PURPOSE:To prevent the temperature of blow-off from being rapidly changed upon mode-change from the bilevel mode to the other mode, in a reheat type air- conditioning system provided with a bilevel blow-off mode, by forming a by-pass passage above a heater core, which by-pass passage is provided with a damper opening upon blow-off in the manual bilevel mode. CONSTITUTION:When a CPU judges that the manual blow-off mode is set and further more, the manual bilevel blow-off mode is set, the CPU delivers a signal to driving circuits 22 through 24 so that a by-pass damper 7, a vent damper 9 and a heat damper 11 are opened by means of drive parts 27 through 29. Thereby, the condition of keeping the heat cold and the feed warm, may be obtained. Further, upon the automatic bilevel blow-off mode, the CPU controls to close the by-pass damper 7. With this arrangement, the condition of keeping the head cold and the feet warm may be obtained upon the manual bilevel blow-off mode, and the abrupt change of the temperature of blow-off upon the switching of the mode from the manual bilevel blow-off mode to the other mode in the automatic blow-off switching mode, may be prevented.

Title: Light source
Inventor: SASAKI MASARU
IPC: H01S5/00
Filed: 1978-08-28
Abstract: PURPOSE:To provide a light source from which effective irradiation of an object achieved by making interference light narrow in width and using an optical system which is simple. CONSTITUTION:A heat sink 2 is made to have a mirror-like surface 2m whereby to reflect laser light 3. Over mirror surface 2m is placed a semiconductor tip 1 so that the latter's active layer 1j is about 2 microns apart from the former's upper surface. Light 4 which is obtained by interference of self-radiation with reflected radiaton is always present only above heat sink 2, with intensity patterns resulting from the interference having the Gaussian distribution, the stretching angle of a single beam being abut 1 degree up-and-down, and with the beam intervals being about 4 degrees. Thus, because of the small stretcing angles and the spaceous intervals of beams, interference light 4 can be focused by means of a simple optical system consisting, for example, of unilens 5-1, and 5-3 and applied exactly to the cores of optical fibers 6-1, 6-2 and 6-3.

Title: Tightening device for cassette of microfilm reader
Inventor: WATANABE IZUMI
IPC: G03B21/11
Filed: 1990-04-20
Abstract: PURPOSE:To prevent a film from loosening during the stop of a reel by stopping a motor by the faster signal of 1st and 2nd stop signals. CONSTITUTION:The increase in the revolution of the reel 18 delays if the number of film winding on the reel 18 is large and thick. The 1st stop signal s1 by a timer 104 is outputted earlier than the 2nd stop signal s2 by the number of revolutions. The motor 62 stops tightening by this 1st stop signal s1. The increase of the revolution of the reel 18 speeds up if the number of winding of the reel 18 is small and thin. The reel 18, therefore, revolves by the set number n0 of revolutions or above before the 1st stop signal s1 by the timer 104 is outputted. The 2nd stop signal s2 is thus outputted early. The motor 62, therefore, stops the tightening by the 2nd stop signal s2. The always correct tightening is executed in this way.

Abstract: PURPOSE:To prevent the gas dispersing part from blocking trouble caused by the adhesion of ashes by a method wherein the dispersing part of an exhaust gas to the inside of a fluidized medium is formed as a dispersing cylinder having many gas gushing ports directed to the down or the slant down direction. CONSTITUTION:Heat is recovered from an exhaust gas G containing a dust via a heat transfer pipe 2 provided in a sand 1 utilized as a fluidized medium. A dispersing cylinder 5 is inserted into a gas dispersing part 3, many gas gushing ports 6 are arranged on the lower part of the dispersing cylinder 5 toward down or slant down direction. At this time, those gas gushing ports 6 are formed of pipes having a diameter larger than approximate 20mm., the lower end parts of the gas gushing ports are cut-off for preventing the adhesion of ashes A. Since the trouble such as the adhesion of ashes on the gas dispersing ports can be prevented, the heat recovery from the exhaust gas having high dust content, heretofore the heat recovery is difficult, is made possible, accordingly, the heat recovery is made extremely effective in saving of energy.

Title: Multi-channel erasing head unit
Inventor: TANAKA TAKASHI
IPC: G11B5/024
Filed: 1978-08-28
Abstract: PURPOSE:To enable to erase only the signal on specific track, by using the magnetic plate small in the saturated magnetic flux density for the spacer of each head element and flowing the erase current simultaneously or selectively to each element. CONSTITUTION:At the gap of tip of the magnetic cores 1,1' of the first and second channels, the spacers 4,4' made of magnetic naterial plate are provided respectively. The saturated magnetic flux density of the spacers 4,4' is made remarkably smaller than that of the magnetic cores 1,1'. If a sufficient greater current to erase the signal on the recording media flows to the winding 3', greater magnetic flux is produced and it is concentrated on the spacer 4'. The magnetic flux density near the spacer 4' is great, the spacer 4' low in the saturated magnetic flux density is saturated, most of the magnetic flux is leaked out to the magnetic recording media in contact with the gap to erase the signal. On the other hand, a part of the magnetic flux is leaked on its way and flows also to the first channel. Since the amount of flux is small, it can not saturate the spacer 4, the flux flows through the spacer 4, and it does not leak externally, and the signal on the first track can never be erased.
