Title: Developing device
Inventor: NOGUCHI TOMIO
IPC: G03G15/08
Filed: 1990-11-27
Abstract: PURPOSE:To reduce the initial torque and improve the assembling property and the quality of image by integrally molding the rotating shaft and carrying part of a means for carrying a developer while stirring it in a developer receiving vessel by use of an elastically deformable member. CONSTITUTION:A developer stirring and carrying means 6 is formed of a rotating shaft and a developer carrying part, and integrally molded by use of an elastically deformable member.

Title: Offset correction method for reluctance angle sensor
Inventor: WAFFENSCHMIDT EBERHARD
IPC: G01R33/09
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To calibrate offset using an inexpensive convenient circuit by determining an offset calibration signal using an angle signal being delivered from a Wheatstone bridge in the absence of DC field as a measure of offset of the Wheatstone bridge. SOLUTION: Total value of output voltages from Wheatstone bridges 1, 2 is maximized only when a DC field acts on the Wheatstone bridges in a direction perpendicular to a first pair of reluctance 3 or a second pair of reluctance 4. After the DC field is removed, a larger shift of a measured output voltage from an offset voltage is measured. Consequently, the output voltage being removed by the Wheatstone bridges 1, 2 is a measure of offset voltage of the Wheatstone bridge. A voltage being delivered from the Wheatstone bridge under absence of DC field is employed by an evaluation circuit for offset correction.

Title: Distributor with built-in crank angle sensor
Inventor: OKAMURA KOICHI
IPC: F02P7/073
Filed: 1990-11-27
Abstract: PURPOSE:To make improvements in noiseproof extent and reliability as well as to miniaturize a dustributor with a built-in crank angle sensor and realize its cost down by having a light emitting element buit-in a light receiving integral circuit as one body. CONSTITUTION:A light receiving element 12 is solidly built in a light receiving integrated circuit 13A, therefore a conventional shield cover and a noise controlling condenser become disused. In brief, since a lead electrode connecting an interval between the element 12 and the IC 13A is extremely subdivided on an IC chip, the extent of noiseproof value is sharply improved, not mention reliability, and moreover a distance between a distributing part and a crank angle sensor unit 7A is reducible. Accordingly, the whole distributor becomes miniaturized and, what is more, a decrease in cost is realized, thus a highly accurate output signal, free from any misoperation is generable from the receiving integrated circuit 13A.

Title: Soft seal gate valve
Inventor: KAJIWARA HIDEKI
IPC: F16K3/00
Filed: 1991-12-06
Abstract: PURPOSE:To generate a force for energizing a valve plate toward an opening direction at the time of closing for reducing a force necessary for opening the valve plate and ensuring the easy opening of the valve plate by forming separate space between a valve box and a valve bottom in close state for communication with space cellularized with a lid above the valve plate. CONSTITUTION:When a valve plate 20 is pushed down at the time of closing operation, fluid is drawn into the first space 28 through a gap generated between the valve plate 20 and a valve box secondary section 12b, thereby raising the internal pressure of the space 28. When the valve plate 20 is further pushed down, a seal member 26 comes in close contact with the internal projection 54 of the section 12b, thereby closing the first space 28 tightly. Concurrently, each of valve seats 22 and 24 comes in close contact with a valve box primary section 12a, thereby cellularizing the second space 56. This space 56 is communicated with the first space 28 via a hole 34 and a cavity 30 and, therefore, the internal pressure of both space 28 and 56 becomes equal. As a result, an upward force F acts on the valve plate 20. According to this construction, a force necessary for opening the valve plate 20 can be reduced and the valve plate 20 can be easily opened.
