Title: Light quantity measuring device
Inventor: TOGAWA HIDEAKI
IPC: G01J1/44
Filed: 1988-12-28
Abstract: PURPOSE:To accurately measure a fine light quantity by mainly generating voltage which coincides with the afterglow characteristic of a photodetector by means of a correction voltage generation circuit. CONSTITUTION:When the photodetector 1 receives external light, a photoelectric current in response to the light quantity is generated and amplified by an operational amplifier 2, then converted into the voltage. At such a time, the output voltage from the amplifier 2 is charged in the capacitor C of the correction voltage generation circuit 6 because a switch 5 is turned on. The correction voltage which coincides with the afterglow characteristic of the element 1 is generated by the circuit 6 and subtracted from the output voltage from the amplifier 2 at the time of measuring the fine light quantity and corrected in terms of an electric circuit so that the output voltage by the true fine light quantity may be obtained. As a result, the element 1 is exposed to the external light and the true light quantity in response to the fine light quantity is accurately measured regardless of a state where the afterglow quantity is not removed, thereby easily and rapidly measuring the light quantity.

IPC: F04D27/00
Filed: 1996-12-13
Abstract: PROBLEM TO BE SOLVED: To monitor whether a fan motor is abnormally rotated or not by detecting an abnormal condition of rotation in the fan motor on the basis of a difference between voltage in proportion to a power supply frequency and voltage in proportion to speed of the fan motor. SOLUTION: In a speed detecting power generator arranged integrated with a fan motor 1 through a rotary shaft 2, ac voltage having volume in proportion to speed of the fan motor 1 is generated.

Voltage from a frequency-voltage converting circuit 7 connected to the ac power supply 6 in parallel with each other, is utilized as the abnormal condition detecting reference voltage V1. It is thus possible to detect an abnormal condition of rotation.

Filed: 1990-11-29
Abstract: PURPOSE:To prevent the separation of a resin from the underside of a support panel by contacting the resin on one of the main surfaces of the support panel to the main surface by filling channel sections with resin. CONSTITUTION:Sealant resin in the open areas of a mold coats the upper surface, lower surface, and sides of a supporting panel 5 and is also injected into the space between the inner walls of a first through hole 12 and a pin 19a and into second and third through holes 13 and 14 and the channel sections 15 and 16. When this resin is cured, a leadframe assembly unit 1 is taken from the molding die 18 and the connectors 8-10 and support lead 7 are removed. At that point, the support lead 7 is pulled off leaving the cut portion of the support lead 7 exposed in the inner section of the resin sealing unit 17. However, since a portion of the resin sealing unit 17 is also formed thinly on the underside of the supporting panel 5, the supporting panel 5 is almost entirely sealed by the resin sealant unit 17. By contacting the thin resin sealing unit 17 formed on the underside of the supporting panel 5 in this way to this panel 5, separation of the resin can be prevented.
