Title: Image forming device
Inventor: SOUMA TAKATAMI
IPC: G03G21/00
Filed: 1988-10-12
Abstract: PURPOSE:To reduce the noise of a fan during idling by altering a gap between an impeller and casings according to the switching of the air capacity of a cooling fan. CONSTITUTION:Upon the completion of copying the number of sheets previously set, a control part causes the device to idle, switches a fan motor to high speed from low speed, and controls the casing gap A of an axial flow fan 16, that is, the gap between the impeller 61 and upper and lower casings 62 and 63, to greatly change the gap. The casings 62 and 63 are formed into one body in an overlapping part 160, and surround the impeller 61. When they rotate in the direction of an arrow, an air flow shown by chain lines with two dots arises and is discharged outside the device. When the gaps A and B are altered, the frequency characteristic of the noise from the fan 16 changes. If the gaps A and B increase, the noise becomes smaller. By making the gaps A and B larger in such a way, the noise of the idling fan can be minimized.

Title: Reagent for manganese measurement and measurement of osteoporosis using the same
Inventor: MAABIN EE GENSHIYAA
IPC: G01N33/84
Filed: 1990-09-28
Abstract: PURPOSE: To detect magnese in humor at a concentration of microgram/liter using porphyrins having a formula selected from a group of specified formulas. CONSTITUTION: In order to catalyze oxidation of oxidationreduction or similar type indicator (1-100mM), an Mn (III) porphyrins complex [5nM (nanomol)-0.1 mM (millimol)) is employed. Manganese forms a complex with porphyrins as shown by a formula and catalyzes oxidation of oxidation-reduction indicator. A manganese/porphyrins complex produced naturally in the humor is detected similarly without requiring complexation through synthetic porphyrins. Since manganese acts as a catalyst, coloring reaction takes place with extremely small quantity (at a concentration of microgram/liter) and thereby an assay system has extremely high sensitivity.
