Title: Film unit with lens
Inventor: OGAWA JUN
IPC: G03C3/00
Filed: 1998-06-26
Abstract: PROBLEM TO BE SOLVED: To provide a film unit with a lens in which the restriction of a molding material of a front cover is eliminated and the degree of freedom of design is widened. SOLUTION: A projection 55 with which a catch 56 formed at a lens presser 54 is engaged is projectingly formed at the outside circumferential wall surface of a shutter cover 52 and an aperture for removing the projection is not formed at the cover 52. The front surface of a shutter blade 26 is covered with the cover 52 without leaving a space. The circumference of an exposure window 25 is provided with a light shielding wall 58 extended up to an identical plane surface to the bottom surface of a shutter base 51 to shield external light entering from a coupling part between the base 51 and the cover 52. The optical path of photographing light passing through a photographing lens 3 is perfectly shielded by the cover 52, a light shielding barrel 57 and a dark box 19.  Thus, it is unnecessary to provide light shielding property to the front cover covering the front surface of a main body base part 41 and a colored resin or a resin having transparency can be used as a molding material of the front cover.

Title: Reconditioned sand for production of casting mold
Inventor: KIUCHI KAZUHIKO
IPC: B22C1/00
Filed: 1993-06-24
Abstract: PURPOSE:To provide the reconditioned sand which has a good flow property, the high strength of the resulted casting mold and hardly generates harmful gases at the time of producing the casting mold. CONSTITUTION:A sulfur element and phosphorus element are incorporated at prescribed balance into this reconditioned sand. Namely, the sulfur element and the phosphorus element are so incorporated therein as to satisfy the formula 0.05<= [sulfur element content/(sulfur element content + phosphorus element content)] <=0.4 by weight. The sulfur element having a high moisture absorption preventive effect is incorporated at a prescribed ratio of the content of the phosphorus element having high hygroscopic power into the reconditioned sand and, therefore, the moisture absorption rate of the reconditioned sand decreases and the flow property thereof is good. The phosphorus element is incorporated at the prescribed ratio of the sulfur element which is the cause for generation of harmful gases into the reconditioned sand and, therefore, the harmful gases are hardly generated. Then, the casting mold having good packability to a pattern and the high strength is obtd. when the casting mold is obtd. by using such reconditioned sand. In addition, the generation of the harmful gases is suppressed at the time of production of the casting mold.

That is, it is that which is wound to the salient poles 321 - 326, therefore, it becomes that which averages the indudtance of the coils arranged extending over a range of a mechanical angle of 180 deg.. Within the range of the mechanical angle of 180 deg., a second harmonic of the inductance corresponding to a one-period portion, therefore, the second harmonic becomes zero since an average value of a one-period portion is taken. In such a way, the second harmonic contained in the inductance is eliminated. The coils of a second - a fourth phases are all the same.
