Title: Hot water supplying apparatus
Inventor: SUZUKI KIWAMU
IPC: F24H1/10
Filed: 1994-12-28
Abstract: PURPOSE: To enable detecting of a trouble quickly and accurately as caused by sticking of a solenoid valve in a hot water supplying apparatus by judging that the solenoid valve operates normally when there is a point of fluctuation in a hourly changing rate based on a first reference value and that the solenoid valve fails to work owing to the sticking when there is no point of fluctuation. CONSTITUTION: A current sensor 4 provided on a solenoid valve 12 measures a current value to be supplied to the solenoid valve 12 to transmit a current value signal to a CPU 20 and the CPU 20 receiving the current value signal stores the current value into a memory 20a in time series. A hourly changing rate is computed until the current value stored in time series shifts to a decrease from the rising of the current and a threshold is stored into an external memory 24 as first reference value to judge whether there is a point of fluctuation or not in the hourly changing rate. Then, the solenoid valve 12 is judged to operate normally when there is the point of fluctuation in the hourly changing rate based on the threshold or otherwise, not to do owing to sticking thereof. Thus, a trouble as caused by the sticking of the solenoid valve 12 is detected quickly.

Title: Multibeam scanning optical system and image-forming device using the same
Inventor: ISHIHARA KEIICHIRO
IPC: G02B26/12
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce a sensitive degree with respect to manufacture error/ assembly errors in respective optical parts and to restrain the change quantity of line pitch intervals to be small. SOLUTION: The difference in image-forming magnification is reduced by narrowing the interval of two luminous fluxes and suppressing an incident angle difference in a position, where light is made incident on an image-forming lens face to be small. More specifically, a sensitive degree with respect to line pitch interval change quantity when a manufacture error and an assembly error occur in respective optical parts is reduced, so that auxiliary scanning direction pixel density is set to be A and (dms.Lap)/(fco.k)<=(1.6/A) is satisfied. It is desirable that a diaphragm 3b deciding the luminous flux width of a main scanning direction be arranged nearest the side of a polygon mirror 5 among optical parts constituting an incident optical system, since it is effective to have it nearer to a deflection reflection face 5a.  Thus, the diaphragm 3 is arranged between a cylindrical lens 4 and the polygon mirror 5.
